question
Elevated blood pressure with a specific cause that often can be identified and corrected. It is usually acute in onset and treated by treating/eliminating the underlying cause.
answer
Secondary hypertension
question
What is the hemodynamic hallmark of hypertension?
answer
Persistently increased systemic vascular resistance
question
Describe the genetic etiology to hypertension.
answer
Having a family history of hypertension is a risk factor for hypertension. This must be a close relative (i.e., sibling, parent, child, etc.).
question
Describe how sodium and water retention can lead to hypertension.
answer
Excessive sodium intake is linked to the start of hypertension. A high sodium intake may activate a number of pressor mechanisms and cause water retention.
question
What 2 populations is the effect of sodium on BP greatest?
answer
1. African Americans 2. Middle-aged and older adults
question
Described how alteration of the RAAS may lead to hypertension?
answer
Too much renin is produced with malfunction of the negative feedback loop. Any rise in the BP should inhibit the release of renin from the kidneys. However, this does not occur in some individuals with hypertension.
question
Describe how increased SNS stimulation results in hypertension.
answer
Causes increased vasoconstriction, increased heart rate, and increased release of renin. Normally, increased SNS stimulation is protective in stressful situations. However, if prolonged, it may result in pathology. People exposed to high levels of repeated psychologic stress develop HTN to a greater extent than those who experience less stress.

answer
1. Stimulates SNS activity 2. Impairs nitric oxide-mediated vasodilation 3. Stimulates vascular hypertrophy 4. Increases renal sodium reabsorption
question
Describe how some individuals with endothelial dysfunction may develop hypertension.
answer
Some people with hypertension have reduced vasodilator production or response to nitric oxide. Some people with hypertension have high levels of endothelin, producing pronounced and prolonged vasoconstriction.
question
True or False: Systolic blood pressure increases with age.
answer
True
question
Describe how gender can be a risk factor for hypertension.
answer
Men in younger adulthood and early middle age (64 y.o. (post-menopausal).
question

answer
1 oz daily
question
Explain how smoking tobacco greatly increases one's risk for developing cardiovascular disease whether they do or do not have hypertension.
answer
Tobacco contains nicotine which is a vasoconstrictor. Increased vasoconstriction causes an elevation in blood pressure, and elevated blood pressure can cause more stress and damage to vessel walls leading to atherosclerosis.
question
What type of obesity is most especially associated with increased frequency of hypertension?
answer
central abdominal obesity
question
When ____________ and _____________ coexist, end organ damage is more severe.
answer
hypertension and diabetes mellitus
question
Why is hypertension termed, the "silent killer?"
answer
Many people who have hypertension don't even know it because they are completely asymptomatic. Essential (primary) HTN can affect anyone at any age, and those with HTN can have it for years before they are diagnosed and begin treatment. Usually patients develop clinical manifestations of end organ damage which prompts them to see their doctor who then discovers their hypertension as the underlying cause.
question
What is the ultimate consequence of hypertension?
answer
End-organ damage
question
What are 3 conditions associated with end-organ damage to the heart (i.e., hypertensive heart disease)?
answer
1. Coronary artery disease (HTN is a major risk factor for CAD) 2. Left ventricular hypertrophy** 3. Heart failure **Progressive LVH, especially in the presence of CAD, can lead to HF.
question
Form of end-organ damage that may occur when BP exceeds the body's ability to autoregulate, the cerebral vessels suddenly dilate, capillary permeability increases, and cerebral edema develops. The subsequent rise in intracranial pressure can cause brain damage and death if left untreated.

answer
**Self-monitoring of BP is an easy, cost-effective approach that may be chosen before ABPM. Patients should take their BP twice a day - first thing in the morning before taking their BP medications and at nighttime just prior to going to bed. This is the best way to assess how well their BP medications are working.
question
What are 2 reasons patients are encouraged to bring their BP cuff and monitor at their office visit?
answer
1. Allows the nurse to ensure the patient is using the proper technique when measuring BP by asking for a return demonstration 2. Allows for verification on the accuracy of the machine
question
Why are patients encouraged to keep a home blood pressure log for one week once every 3 months even after their blood pressure is controlled?
answer
It helps patients see improvement and maintenance of a goal BP which improves compliance.
question

Decreased adrenergic receptor sensitivity 5. Blunting of baroreceptor reflexes 6. Decreased renal function 7. Decreased renin response to sodium and water depletion
question
Name 2 drug pharmacokinetic changes that should be considered in older adults being treated for hypertension.
answer
1. Absorption of some drugs may be altered as a result of decreased blood flow to the gut 2. Metabolism and excretion may also be prolonged due to the natural decline in liver and kidney function. This can lead to possible toxicity and dosing issues as well as electrolyte imbalances.
question
Why should vasoactive medications not be given with or before meals in older adults?
answer
Older adults experience postprandial drops in blood pressure. The greatest decrease occurs approximately 1 hour after eating. These medications, therefore, should be given between/after meals.
question
Type of drug often taken by older adults for their arthritis (the second most prevalent disease in older adults) that can cause loss of blood pressure control and heart failure. There is the potential for adverse renal effects and/or hyperkalemia when these drugs are used with ACE-Is, ARBs, or aldosterone antagonists.
answer
NSAIDs
question
What type of antihypertensive should always be the first or second drug ordered for blood pressure control in older adults?
answer
diuretic
question
The nurse teaches a patient with hypertension that uncontrolled hypertension may damage organs in the body primarily by which mechanism? a. Hypertension promotes atherosclerosis and damage to the walls of the arteries. b. Hypertension causes direct pressure on organs, resulting in necrosis and replacement of cells with scar tissue. c. Hypertension causes thickening of the capillary membranes, leading to hypoxia of organ systems. d. Hypertension increases blood viscosity, which contributes to intravascular coagulation and tissue necrosis distal to occlusions
answer
Answer: A Hypertension is a major risk factor for the development of atherosclerosis by mechanisms not yet fully known. However, once atherosclerosis develops, it damages the walls of arteries and reduces circulation to target organs and tissues.
question
When teaching a patient about dietary management of stage 1 hypertension, which instruction is most appropriate? a. Restrict all caffeine. b. Restrict sodium intake. c. Increase protein intake. d. Use calcium supplements.
answer
Answer: B --> The patient should decrease intake of sodium. This will help to control hypertension, which can be aggravated by excessive salt intake, which in turn leads to fluid retention. Wrong Answers: Caffeine and protein intake do not affect hypertension. Calcium supplements are not recommended to lower BP.
question
In caring for a patient admitted with poorly controlled hypertension, which laboratory test result should the nurse understand as indicating the presence of target organ damage? a. BUN of 15 mg/dL b. Serum uric acid of 3.8 mg/dL c. Serum creatinine of 2.6 mg/dL d. Serum potassium of 3.5 mEq/L
answer
Answer: C --> The normal serum creatinine level is 0.6-1.2 mg/dL. This elevated level indicates target organ damage to the kidneys. Normal BUN levels = 7-18 mg/dL Normal potassium levels = 3.5-5.0 mEq/L
question
When providing dietary instruction to a patient with hypertension, the nurse would advise the patient to restrict intake of which meat? a. Broiled fish b. Roasted duck c. Roasted turkey d. Baked chicken breast
answer
Answer: B Roasted duck is high in fat, which should be avoided by the patient with hypertension. Weight loss may slow the progress of atherosclerosis and overall CVD risk. The other meats are lower in fat and are therefore acceptable in the diet.
question
The nurse is caring for a patient admitted with a history of hypertension. The patient's medication history includes hydrochlorothiazide (Hydrodiuril) daily for the past 10 years. Which parameter would indicate the optimal intended effect of this drug therapy? a. Weight loss of 2 lb b. Blood pressure 128/86 c. Absence of ankle edema d. Output of 600 mL per 8 hours
answer
Answer: b Hydrochlorothiazide may be used alone as monotherapy to manage hypertension or in combination with other medications if not effective alone. After the first few weeks of therapy, the diuretic effect diminishes, but the antihypertensive effect remains. Since the patient has been taking this medication for 10 years, the most direct measurement of its intended effect would be the blood pressure.
question
In reviewing medication instructions with a patient being discharged on antihypertensive medications, which statement would be most appropriate for the nurse to make when discussing guanethidine (Ismelin)? a. "A fast heart rate is a side effect to watch for while taking guanethidine." b. "Stop the drug and notify your doctor if you experience any nausea or vomiting." c. "Because this drug may affect the lungs in large doses, it may also help your breathing." d. "Make position changes slowly, especially when rising from lying down to a standing position."
answer
Answer: D Guanethidine is a peripheral-acting α-adrenergic antagonist and can cause marked orthostatic hypotension. For this reason, the patient should be instructed to rise slowly, especially when moving from a recumbent to a standing position. Support stockings may also be helpful. Tachycardia or lung effects are not evident with guanethidine.
question
The nurse is caring for a patient admitted with chronic obstructive pulmonary disease (COPD), angina, and hypertension. Before administering the prescribed daily dose of atenolol 100 mg PO, the nurse assesses the patient carefully. Which adverse effect is this patient at risk for, given the patient's health history? a. Hypocapnia b. Tachycardia c. Bronchospasm d. Nausea and vomiting
answer
Answer: C Atenolol is a cardioselective β1-adrenergic blocker that reduces blood pressure and could affect the β2-receptors in the lungs with larger doses or with drug accumulation. Although the risk of bronchospasm is less with cardioselective β-blockers than nonselective β-blockers, atenolol should be used cautiously in patients with COPD.
question
The nurse is caring for a patient with hypertension who is scheduled to receive a dose of esmolol (Brevibloc). The nurse should withhold the dose and consult the prescribing physician for which vital sign taken just before administration? a. Pulse 48 b. Respirations 24 c. Blood pressure 118/74 d. Oxygen saturation 93%
answer
Answer: A Because esmolol is a β1-adrenergic blocking agent, it can cause hypotension and bradycardia as adverse effects. The nurse should withhold the dose and consult with the health care provider for parameters regarding pulse rate limits.
question
Despite a high dosage, a male patient who is taking nifedipine (Procardia XL) for antihypertensive therapy continues to have blood pressures over 140/90 mmHg. What should the nurse do next? a. Assess his adherence to therapy. b. Ask him to make an exercise plan. c. Instruct him to use the DASH diet. d. Request a prescription for a thiazide diuretic.
answer
Answer: A A long-acting calcium-channel blocker such as nifedipine causes vascular smooth muscle relaxation resulting in decreased SVR and arterial BP and related side effects. The patient data the nurse has about this patient is very limited, so the nurse needs to assess his adherence to therapy.
question
The nurse is teaching a women's group about prevention of hypertension. What information should be included in the teaching for all the women (select all that apply)? a. Lose weight. b. Limit nuts and seeds. c. Limit sodium and fat intake. d. Increase fruits and vegetables. e. Exercise 30 minutes most days.
answer
Answer: C, D, and E Primary prevention of hypertension is to make lifestyle modifications that prevent or delay the increase in BP. E) Along with exercise for 30 minutes on most days, the (C) and (D) DASH eating plan is a healthy way to lower BP by limiting sodium and fat intake, increasing fruits and vegetables, and increasing nutrients that are associated with lowering BP. (B) Nuts and seeds and dried beans are used for protein intake. (A) Weight loss may or may not be necessary for the individual.
question
When assessing the patient for orthostatic hypotension, after taking the blood pressure (BP) and pulse (P) in the supine position, what should the nurse do next? a. Repeat BP and P in this position. b. Take BP and P with patient sitting. c. Record the BP and P measurements. d. Take BP and P with patient standing.
answer
Answer: B When assessing for orthostatic changes in BP after measuring BP in the supine position, the patient is placed in a sitting position and BP is measured and then repositioned to the standing position with BP measured again. The results are then recorded with a decrease of 20 mm Hg or more in SBP, a decrease of 10 mm Hg or more in DBP, and/or an increase in pulse of greater than or equal to 20 beats/minute from supine to standing indicating orthostatic hypotension.
question
The patient has chronic hypertension. Today she has gone to the ED, and her blood pressure has risen to 200/140. What is the priority assessment for the nurse to make? a. Is the patient pregnant? b. Does the patient need to urinate? c. Does the patient have a headache or confusion? d. Is the patient taking antiseizure medications as prescribed?
answer
Answer: C The nurse's priority assessments include neurologic deficits, retinal damage, heart failure, pulmonary edema, and renal failure. The headache or confusion could be seen with hypertensive encephalopathy from increased cerebral capillary permeability leading to cerebral edema. Wrong Answers: A) Pregnancy can lead to secondary hypertension. B) and D) Needing to urinate and taking antiseizure medication do not support a hypertensive emergency.
question
When collecting subjective data related to the cardiovascular system, which information should be obtained from the patient (select all that apply)? a. Annual income b. Smoking history c. Religious preference d. Number of pillows used to sleep e. Blood for basic laboratory studies
answer
Answer: B, C, D
question
When assessing the cardiovascular system of a 79-year-old patient, you might expect to find a. a narrowed pulse pressure. b. diminished carotid artery pulses. c. difficulty in isolating the apical pulse. d. an increased heart rate in response to stress.
answer
Answer: C Myocardial hypertrophy and the downward displacement of the heart in an older adult may cause difficulty in isolating the apical pulse.
question
Which BP-regulating mechanism(s) can result in the development of hypertension if defective (select all that apply)? a. Release of norepinephrine b. Secretion of prostaglandins c. Stimulation of the sympathetic nervous system d. Stimulation of the parasympathetic nervous system e. Activation of the renin-angiotensin-aldosterone system
answer
Answer: A, C, E Norepinephrine (NE) is released from the sympathetic nervous system nerve endings and activates receptors located in the vascular smooth muscle. When the α-adrenergic receptors in smooth muscle of the blood vessels are stimulated by NE, vasoconstriction results. Increased sympathetic nervous system stimulation produces increased vasoconstriction and increased renin release. Increased renin levels activate the renin-angiotensin-aldosterone system, leading to elevation in blood pressure (BP).
question
While obtaining subjective assessment data from a patient with hypertension, the nurse recognizes that a modifiable risk factor for the development of hypertension is a. a low-calcium diet. b. excessive alcohol consumption. c. a family history of hypertension. d. consumption of a high-protein diet.
answer
Answer: B Alcohol intake is a modifiable risk factor for hypertension. Excessive alcohol intake is strongly associated with hypertension. Patients with hypertension should limit their daily intake to 1 oz of alcohol.
question
In teaching a patient with hypertension about controlling the condition, the nurse recognizes that a. all patients with elevated BP require medication. b. obese persons must achieve a normal weight to lower BP. c. it is not necessary to limit salt in the diet if taking a diuretic. d. lifestyle modifications are indicated for all persons with elevated BP.
answer
Answer: D
question
A major consideration in the management of the older adult with hypertension is to a. prevent primary hypertension from converting to secondary hypertension. b. recognize that the older adult is less likely to adhere to the drug therapy regimen than a younger adult. c. ensure that the patient receives larger initial doses of antihypertensive drugs because of impaired absorption. d. use careful technique in assessing the BP of the patient because of the possible presence of an auscultatory gap.
answer
Answer: D Careful technique is important in assessing BP in older adults. In some older people, there is a wide gap between the first Korotkoff sound and subsequent beats; such a wide interval is called an auscultatory gap. Failure to inflate the cuff high enough may result in a serious underestimate of systolic BP.
question
A patient with newly discovered high BP has an average reading of 158/98 mm Hg after 3 months of exercise and diet modifications. Which management strategy will be a priority for this patient? a. Medication will be required because the BP is still not at goal. b. BP monitoring should continue for another 3 months to confirm a diagnosis of hypertension. c. Lifestyle changes are less important, since they were not effective, and medications will be started. d. More vigorous changes in the patient's lifestyle are needed for a longer time before starting medications.
answer
Answer: A The patient has hypertension, stage 1. Lifestyle modifications will continue, but drug initiation of therapy is a priority. Reduction of BP can help to prevent serious complications related to hypertension.
question
A patient is admitted to the hospital in hypertensive emergency (BP 244/142 mm Hg). Sodium nitroprusside is started to treat the elevated BP. Which management strategy(ies) would be appropriate for this patient (select all that apply)? a. Measuring hourly urine output b. Decreasing the MAP by 50% within the first hour c. Continuous BP monitoring with an intraarterial line d. Maintaining bed rest and providing tranquilizers to lower the BP e. Assessing the patient for signs and symptoms of heart failure and changes in mental status
answer
Answer: A, C, E Measure urine output hourly to assess renal perfusion. Patients being treated with IV sodium nitroprusside should have continuous intraarterial BP monitoring. Hypertensive crisis can cause encephalopathy, intracranial or subarachnoid hemorrhage, acute left ventricular failure, myocardial infarction, renal failure, dissecting aortic aneurysm, and retinopathy. The initial treatment goal is to decrease the mean atrial pressure (MAP) by no more than 25% within minutes to 1 hour. Patients receiving IV antihypertensive drugs may be restricted to bed rest. Getting up (e.g., to use the toilet) may cause severe cerebral ischemia and fainting.

answer
Chronic kidney disease (CKD)
question
Why are patients with chronic kidney disease often underdiagnosed and undertreated?
answer
Even though our kidneys cannot repair, they are extremely adaptive. This can be an issue because many people don't know they have CKD because their kidneys are compensating so well. Approximately 80% of GFR can be lost before CKD is diagnosed.

answer
Uremia
question
True or False: Patients stop producing urine (anuria) once they are placed on dialysis.
answer
False - It takes a while for the body to stop producing urine even if CKD is present. Typically, patients become anuric after they have been on dialysis for awhile.
question
What is the leading cause and 2nd leading cause of CKD?
answer
Leading cause = diabetes mellitus 2nd leading cause = hypertension
question
Why do some individuals in the early stages of CKD NOT experience a decrease in urine output?
answer
Diabetes mellitus is the leading cause of CKD, and a common symptom of DM is polyuria. Therefore, the lack of decrease in the urine output during the initial stages of CKD is more so a result of DM rather than CKD.
question
A possible clinical manifestation of CKD is altered carbohydrate metabolism. Cells can become insensitive to the normal action of ____________, leading to mild to moderate hyperinsulinemia and hyperglycemia.
answer
insulin
question
True or False: Patients with diabetes who develop uremia may require less insulin than before the onset of CKD.
answer
True Because patients with CKD have a decrease in GFR, they also have a decrease in the excretion of insulin allowing it to remain in circulation longer. As a result, a number of patients who required insulin before starting dialysis will be able to discontinue it when they start dialysis and their kidney disease progresses.

question
How many needles are inserted into the fistula or graft when a patient receives hemodialysis? What is occurring there?
answer
1. 2 large needles are inserted into the fistula or graft to obtain vascular access 2. One needle is placed to pull blood from circulation to the dialysis machine, and the second needle is used to return the dialyzed blood back to the patient.
question
What is added to the blood of a hemodialysis patient as it flows into the dialyzer to prevent clotting?

question
What is a good piece of information to recommend to patients on hemodialysis prior to coming to their hemodialysis appointment?
answer
Do not take BP medications as hypotension is a common side effect of dialysis **If this is an admitted patient, phone the physician and ask if you can hold their blood pressure medication until after dialysis is performed
question
Why is anemia a special concern for patients on hemodialysis?
answer
They are at increased risk for bleeding because blood may not be completely rinsed from the dialyzer, and bleeding after the removal of the needle at the end of dialysis may be excessive if too much heparin was administered. Other complications that can occur while receiving HD are rupture of the dialysis membrane and accidental separation of the blood tubing.
question
What is a complication of hemodialysis for both the patient and caregiver due to the increased exposure to blood during exchanges?
answer
Hepatitis ** All patients and care providers are vaccinated for hepatitis B and C as a preventative measure
question
Under normal cellular biology, describe the relationship between cell proliferation/reproduction and cellular degeneration/death.
answer

answer
actively dividing/proliferating/reproducing
question
What 2 major dysfunctions are present in the process of cancer?
answer
Dysfunction in 1. Cellular proliferation 2. Cellular differentiation
question
What about cancer cell proliferation is abnormal?
answer
Cancer cells lack contact inhibition. They have no regard for cell boundaries and grow on top of one another and also on top of or between normal cells.
question
True or false: Cancer cells proliferate at a faster rate than that of the normal body cells from their tissue of origin.
answer
False - This is a common misconception. Cancer cells usually proliferate at the same rate as the normal cells of the tissue from which they arise. They differ from normal cells because they proliferate indiscriminately and continuously.
question

answer
epithelial lining of the GI tract, hair follicles, bone marrow
question
Cells that _______ reproduce are most affected by chemotherapy and radiation.
answer
rapidly

They have a high incidence of (3) ________ (abnormally high or low DNA content) and (4) ________ proliferative indices. These tumors (5) ________ recur and are usually (6) ___________ to hormone therapy.
answer
1) negative 2) poorly 3) aneuploidy 4) higher 5) frequently 6) unresponsive
question
Triple negative breast cancer tests negative for what 3 receptor types?
answer
estrogen, progesterone, HER-2/neu
question
In what 4 populations is the incidence of triple negative breast cancer higher?
answer
1. Hispanic women 2. African American women 3. Younger women 4. Women with a BRCA 1 gene mutation
question
Women with triple negative breast cancer tend to have more (1) _________ tumors with a (2) _______ prognosis. This is because most of the treatments available work at 1 or more of the 3 receptor types that are absent in these patients.
answer
1) aggressive 2) poorer
question
What is considered the primary treatment for breast cancer?
answer
Surgery
question
Procedure in which the axillary nodes and nodes near the tumor (~12-20 nodes) are removed. This can result in multiple negative side effects including immunosuppression and impaired circulation/lymphedema.
answer
Axillary lymph node dissection (ALND)
question
A partial mastectomy which usually involves the removal of the entire tumor along with a margin of normal surrounding tissue. These patients usually receive RT and/or SLND and possible ALND. It preserves the breast, including the nipple. The goal of combined surgery and radiation is to maximize the benefits of both cancer treatment and cosmetic outcome while minimizing risks.
answer
Lumpectomy
question
Removal of the breast and axillary lymph nodes but preserves the pectoralis major muscle. When performed, the patient has the option of breast reconstruction which can be performed immediately after the procedure, or it can be delayed until postoperative recovery is complete.
answer
Modified radical mastectomy
question
What are 2 points of emphasis with post-operative care in patients who have received surgical treatment for their breast cancer (i.e., SLND, ALND, lumpectomy, modified radical mastectomy)?
answer
1. Preserve ROM 2. Prevent/reduce lymphedema
question
When assessing a patient who has recently underwent breast cancer surgery (i.e., SLND, ALND, lumpectomy, or modified radical mastectomy), what should you be focusing on?
answer
1. Ability to maintain normal ADLs 2. Comparing the effected arm to the non-effected arm 3. Comparing the function of the effected arm prior to surgery and after surgery
question
Chronic swelling related to interrupted lymphatic circulation. Functioning lymph channels cannot adequately return flow of lymph fluid to the general circulation, resulting in fluid accumulation in the interstitial spaces. It is a common side effect for post-mastectomy patients, especially if they also received an ALND.
answer
Lymphedema
question
What are 4 methods of treating lymphedema in a patient who has just underwent breast cancer surgery?
answer
1. Elevating the effected arm above the level of the heart 2. Gentle muscle pumping 3. Compression sleeve 4. Exercises to preserve rOM
question
True or False: After a patient is treated for lymphedema, they most likely will not develop it again.
answer
False - Once a patient develops lymphedema, they are more likely to get it again later in life.
question
What is an important nursing implication for a patient suffering from lymphedema after breast cancer surgery in a specific arm?
answer
The patient should not have a BP taken, venipuncture performed, or injections given here.
question
What are 2 types of breast reconstructive surgeries for patients who have underwent a modified radical mastectomy of one or both breasts?
answer
1. Tissue expander 2. TRAM FLAP = Transverse Rectus Abdominus Myocutaneous flap
question
Describe how a tissue expander is a form of breast reconstruction.
answer
The tissue expander is placed in a pocket under the pectoralis major, which protects the implant and provides soft tissue coverage. It is then minimally inflated and then gradually filled by weekly injections of sterile water or saline solution, stretching the skin and muscle. The expander is eventually surgically removed, and a permanent implant is inserted. This procedure can be very painful but is the most common breast reconstruction technique used.
question
Procedure in which a large block of tissue from the lower abdominal area, attached to the rectus abdominus muscle, is used to fashion a breast. The abdominal incision is closed, giving the patient a result that is similar to having an abdominoplasty ("tummy tuck").
answer
TRAM Flap = Transverse Rectus Abdominus Myocutaneous Flap
question
CMF is a form of breast cancer therapy. What does CMF stand for?
answer
C = Cyclophosphamide (Ctyoxan) **Can be nephrotoxic and cause hemorrhagic cystitis M = Methotrexate F = Fluorouracil
question
Taxol and adriamycin are 2 types of chemotherapeutic agents used to treat what type of cancer?
answer
breast cancer **Adriamycin can be cardiotoxic causing decreased contractility of the myocardium, reduced EF, and possible heart failure.
question
What are 2 types of hormone therapies that can be used in treating breast cancer that is estrogen positive?
answer
1. tamoxifen (Nolvadex) 2. anastrozole (Arimidex)
