Question 4

A nurse, preparing a sterile field on which to perform a dressing change, places the sterile drape on the overbed table. Which of these actions on the part of the nurse indicate correct understanding of the principles of aseptic technique? Select all that apply.

Answer

B Positioning the sterile field so that it remains in full view E Picking up a pair of sterile scissors from the sterile field with a sterile gloved hand F Pouring sterile wound cleansing solution into a sterile cup before donning sterile gloves Rationale: The principles of surgical asepsis must be followed in the preparation of a sterile field. Among these principles: A sterile object remains sterile only when touched by other sterile objects; only sterile objects may be placed on a sterile field; a sterile object or field out of the range of vision or an object held below the nurse’s waist is to be considered contaminated; a sterile object or field becomes contaminated with prolonged exposure to air; when a sterile surface comes in contact with a wet, contaminated surface, the sterile object or field becomes contaminated by way of capillary action; fluid flows in the direction of gravity; a 1-inch edge of a sterile field or container is to be considered contaminated.

Question 6

How would the nurse prepare insulin to ensure its efficacy? Do not allow refrigerated insulin to warm up before administering it. Follow aseptic technique during the entire process. Roll the vial of insulin suspension between the palms prior to drawing up the medication. Monitor the patient’s blood glucose level before administering the injection.

Answer

Roll the vial of insulin suspension between the palms prior to drawing up the medication. CORRECT. Rolling the vial of insulin suspension before drawing up the medication ensures that particles of suspension are adequately distributed into the solution, ensuring efficacy.

Question 7

Which action would the nurse take to minimize a patient’s risk for injury during urinary catheter irrigation? Change the tubing every 8 hours. Use slow, even pressure when injecting the irrigating fluid. Adhere to aseptic technique during the irrigation process. Monitor the patient’s temperature every 4 hours.

Answer

Use slow, even pressure when injecting the irrigating fluid. Adhere to aseptic technique during the irrigation process. Monitor the patient’s temperature every 4 hours. CORRECT. This is the correct answer. Using slow, even pressure during the instillation of fluid into the bladder helps avert bladder trauma.

Question 8

• 1. Which of the following scenarios best reflects the concept of nonmaleficence, rather than beneficence? A. Administering painkillers to a post-op patient B. Helping a patient brush her teeth C. Intervening when a colleague is not following proper aseptic technique D. Educating a patient with a broken hip about physical therapy

Answer

Answer: C Rationale: Administering medications, aiding with personal hygiene, and referring patients for further healthcare all fall under beneficence, which menas “doing good”. Nonmaleficence, on the other hand, means to “do no harm”. Preventing the improper use of aseptic technique is an example of doing no harm.

Question 9

What event in the surgical suite represents a violation of aseptic technique? A glove contacts the leg of the table that supports the sterile field. Correct The cuff of the scrub nurse’s sterile gown contacts the sterile field. The sterile field was established at 0650, and the current time is 0900. Bacteria are present in the nares and upper respiratory passages of the nurse.

Answer

A glove contacts the leg of the table that supports the sterile field. Correct Tables are sterile only at tabletop level. Areas below this are considered contaminated. The sterile gown below the point 2 inches above the elbow is considered sterile. The passage of time in and of itself does not necessarily render a field contaminated. Bacteria are inevitable in the respiratory passages of team members, but they present a threat to sterility only if they are not confined by attire. Awarded 1.0 points out of 1.0 possible points
