Nursing Process Questions

Correct Answer: A

Rationale: The correct answer is A: Use aseptic technique for the insertion site. Aseptic technique is necessary to prevent infection when accessing the intracranial pressure monitoring system. Aseptic technique involves maintaining a sterile field during the insertion process, reducing the risk of introducing pathogens. Using clean technique for cleansing connections (choice B) may introduce contaminants to the insertion site. Sterile technique for cleansing the insertion site (choice C) is not necessary and may be overly stringent. Closing leaks in the tubing with tape (choice D) does not address the prevention of infection at the insertion site.

Correct Answer: A

Rationale: Correct Answer: A Rationale: 1. Dressing changes twice a day help maintain a clean wound environment, reducing the risk of infection. 2. Regular dressing changes promote proper wound healing by facilitating moisture balance and removal of dead tissue. 3. It is a direct intervention that addresses the patient's poor wound healing. 4. Teaching the patient about signs of infection (B) is important but does not directly address the wound healing process. 5. Instructing the family on dressing changes (C) is helpful but should not substitute direct patient care. 6. Refocusing the patient from body image changes (D) is not directly related to improving wound healing.

Correct Answer: B

Rationale: The correct answer is B (Lifetime dependency on hormone replacement) because after hypophysectomy (removal of the pituitary gland), patients will no longer produce essential hormones like growth hormone, thyroid-stimulating hormone, etc. Therefore, they will require lifelong hormone replacement therapy to maintain normal bodily functions. A: Abnormal distribution of body hair is not directly related to hypophysectomy. C: While fluid intake may be important post-surgery, it is not the primary focus of teaching. D: There is typically no need for repeat surgical procedures after a hypophysectomy, as it is a one-time surgery to address specific issues. In summary, choice B is correct as it directly addresses the long-term implications of the surgery on hormone production and the need for replacement therapy, while the other choices are not directly relevant to the post-operative care of hypophysectomy patients.

Correct Answer: C

Rationale: The correct answer is C: 125 mL/h. To calculate the infusion rate per hour, we divide the total volume (1000 mL) by the total time in hours (8 hours). 1000 mL / 8 hours = 125 mL/h. This ensures a consistent and accurate infusion rate throughout the 8-hour period. Choice A (80 mL/h) is incorrect because it underestimates the infusion rate. Choice B (100 mL/h) is incorrect because it does not divide the total volume by the total time correctly. Choice D (150 mL/h) is incorrect because it overestimates the infusion rate.

Correct Answer: C

Rationale: The correct answer is C because in myasthenia gravis, which is characterized by muscle weakness and fatigue, the administration of edrophonium will temporarily improve muscle strength due to increased availability of acetylcholine at the neuromuscular junction. This improvement should be noted within 30 to 60 seconds after the administration of the medication. Choice A is incorrect because joint pain is not a typical response to edrophonium in the context of myasthenia gravis. Choice B is incorrect because feelings of faintness, dizziness, hypotension, and flushing are more indicative of a cholinergic crisis, which occurs when too much edrophonium is administered. Choice D is incorrect because an increase in muscle strength post-edrophonium administration would not be expected in a client with myasthenia gravis.
