ECG shows right ventricular hypertrophy. Explanation for absence of murmur on initial exam?
High pulmonary vascular resistance

VSD murmurs can arise from lower muscular part or upper membranous part. Lower muscular ones heal on their own and dont give much problem. Upper portion defects stay on for long and do give the particular holosystolic murmur described in the question stem. The murmur is not heard just after birth at the initial exam, reason being the pulmonary vascular resistance is too high and lungs are not totally functional. So No blood is flowing through the pulmonary system until high oxygen later on after birth shuts down the PDA and loosens up the pulm vasc resistance.

35) An 18 yo woman has had fever 12 hrs and obtundation 4 hrs. She had been attending a summer camp with 120 other students and was well until yesterday, when she developed a sore throat and nonproductive cough; this morning she couldn’t be aroused.

36) Five days after undergoing an open splenectomy for immune thrombocytopenic purpura, a 57 year old woman has the onset of shortness of breath. During the operation, dissection of the splenic hilum was difficult. Her only medication is morphine. Her temperature is 37.3°C (99.2°F), pulse is 80/min, respirations are 20/min, and blood pressure is 120/80 mm Hg. The surgical wound appears normal. Breath sounds are decreased at the left lung base. Her leukocyte count is 15,600/mm , platelet count is 112,000/mm , and serum amylase activity is 90 U/L. Which of the following is the most appropriate next step in management?
CXR (unsure)
37) Newborn with B/L clubfoot deformity. Born at term following uncomplicated preg and delivery. Did not more his lower extremities immediately after birth, did not cry when he receied a needlestick in his feet. On exam, he is vigorous and moves his upper extremirites but not his lower extremities. Bladder is palpable and full, Dx?
Spinal dysraphism

NOT cerebral palsy

In spinal dysraphism:
Look for h/o tufts of hair , (which is not present in this case) but if u see the child can move upper extremities and not lower ext, also no sensation in lower ext ( note: this does not happen in CP—In CP there will be weakness involving both upper/lower ext in the form of spacticity or wherever the hypoxic injury has injured the part of the brain,but not such discrepancy (only lower ext affected with upper ext being normal in above vignette )since the brain is involved in CP —brain injury due to hypoxia/vascular insufficiency mostly inutero)

vs spinal dysraphism— is an umbrella term and neural tube defects come under it ;the tufts of hair with tethered cord is one of the occult spinal dysraphism ,
Here spinal cord /peripheral nerves is affected and the above vignette has clearly mentioned lower ext weakness and no sensation in lower ext but the child is moving upper ext (spared); also bladder is full so lesion is below the spinal cord involved ,most likely tethered cord in this case!!
also, club foot (another hint) associated with spinal dysraphism!!

38) 77 year old man brought to the emergency deparment after 15 minutes since the onset of cough productive of large amounts of blood tinged sputum, life long history of chronic productive cough and recurrent episodes of pneumonia in the right lower lobe of the lunge, 15 minutes after arriving the bleeding stops spontaneously his temp is ok, pulse is 110, resp 24, bp OK exam shows bronchophony in the right lateral lungm CXR shows thin walled cystic spaces in the right lower loe with some air fluid levels., which is the most likely explanation of these findings?

.Bronchiectasis…Lung CXR might be showing Lung abscess…

Lung abscesses can be classified based on the duration and the likely etiology. Acute abscesses are less than 4-6 weeks old, whereas chronic abscesses are of longer duration. Primary abscesses are infectious in origin, caused by aspiration or pneumonia in the healthy host. Secondary abscesses are caused by a preexisting condition (eg, obstruction), spread from an extrapulmonary site, bronchiectasis, and/or an immunocompromised state.

****
4. classic galactosemia.. as they have decreeased ATP and accumulation of Gal-1-P… less glu-1 phosphate for gluconeogenesis… and also a lot of aldose reductase activity .. which leads to reducing stuff in urine.. also note in the question …. after feeds sumtime the symptoms develop… as lactose broken down to gluc and galact.. galact is not metabolised .. so leads to hypoglycemia… very important condition … treat by avoiding strictly breast feed or milk .. but soy milk bsed diet is good…. so Decreased gluconeogenesis is the answer.
