What nursing action should the nurse perform when fatigue is undergoing a comprehensive assessment caring for a patient undergoing diagnostic testing of the which includes test of renal function relating to renal-urologic system?
- A. Withhold medications until 12 hours post-testing.
- B. Ensure that the patient knows the importance of of what blood value? temporary fluid restriction after testing.
- C. Hematocrit
- D. Inform the patient of his or her medical diagnosis after
Correct Answer: B
Rationale: Rationale: Option B is correct because it addresses the importance of temporary fluid restriction after renal function testing, which is crucial in maintaining accurate test results. Ensuring patient understanding and compliance with fluid restriction helps prevent dilution of blood samples, leading to more accurate diagnostic outcomes.
Summary:
A: Withholding medications post-testing is not necessary for fatigue assessment related to renal function testing.
C: Hematocrit is not directly related to the temporary fluid restriction after renal function testing.
D: Informing the patient of their medical diagnosis is not relevant when assessing fatigue during diagnostic testing of renal function.

The drug of choice for monilial diarrhea is:
- A. Amphothericin B
- B. Nystatin
- C. Ketoconazole
- D. Itraconazole
Correct Answer: B
Rationale: Step-by-step rationale for why Nystatin is the correct choice for monilial diarrhea:
1. Nystatin is an antifungal medication specifically effective against Candida species causing monilial infections.
2. It works by binding to ergosterol in fungal cell membranes, disrupting membrane integrity and causing cell death.
3. Nystatin is not absorbed systemically, making it suitable for gastrointestinal infections.
4. Amphothericin B is reserved for severe systemic fungal infections due to its significant toxicity. Ketoconazole and Itraconazole are not typically used for gastrointestinal Candida infections, as they are more commonly used for systemic fungal infections.
Which antibiotics should be avoided in patients of liver disease?:
- A. Tetracycline
- B. Cotrimoxazole
- C. Cephalexin
- D. Ethanbutol
Correct Answer: A
Rationale: The correct answer is A: Tetracycline. Tetracycline should be avoided in patients with liver disease due to its potential hepatotoxicity. Tetracycline is primarily metabolized in the liver and can exacerbate liver damage in patients with pre-existing liver conditions. Cotrimoxazole, Cephalexin, and Ethambutol are generally considered safe for use in patients with liver disease as they are not known to cause significant liver toxicity.
Patients with nephrolithiasis or kidney stones need to increase fluid intake. This is to:
- A. Concentrate the urine.
- B. Help flush the stones through the urinary tract.
- C. Crystallize the struvite from the renal tubules.
- D. Break down the stones into smaller pieces that will more easily pass through the urinary tract.
Correct Answer: B
Rationale: The correct answer is B: Help flush the stones through the urinary tract. Increasing fluid intake can help dilute the urine, preventing stone formation and aiding in the passage of existing stones. Adequate hydration promotes frequent urination, which can help flush out the stones and reduce the risk of complications. Choices A, C, and D are incorrect. A: Concentrating the urine can actually exacerbate stone formation. C: Struvite crystals are not typically formed in nephrolithiasis. D: Breaking down stones requires medical intervention, not just increased fluid intake.
Due to its potential for severe hepatoxicity, Nevirapine should NOT be * initiated in:
- A. Women with CD4 cell counts >150 cells/mm3 or in men with CD4 cell count >400 cells/mm3
- B. Women with CD4 cell counts >250 cells/mm3 or in men with CD4 cell count >400 cells/mm3
- C. Women with CD4 cell counts >250 cells/mm3 or in men with CD4 cell count >500 cells/mm3
- D. Women with CD4 cell counts >250 cells/mm3 or in men with CD4 cell count >450 cells/mm3
Correct Answer: D
Rationale: The correct answer is D because Nevirapine is associated with an increased risk of severe hepatoxicity, especially within the first few weeks of treatment initiation. The recommended CD4 cell count thresholds for starting Nevirapine are lower in women compared to men to minimize this risk. In this case, women with CD4 cell counts >250 cells/mm3 and men with CD4 cell counts >450 cells/mm3 should not initiate Nevirapine due to the higher likelihood of developing hepatoxicity.
A is incorrect because the CD4 cell count thresholds are too high for both women and men. B is incorrect as it sets the threshold for women too high. C is incorrect because the threshold for men is too high. Thus, D is the most appropriate choice based on the recommended guidelines to minimize the risk of severe hepatoxicity.
In which type of dialysis does the patient dialyze during sleep and leave the fluid in the abdomen during the day?
- A. Long nocturnal hemodialysis
- B. Automated peritoneal dialysis (APD)
- C. Continuous venovenous hemofiltration (CVVH)
- D. Continuous ambulatory peritoneal dialysis (CAPD)
Correct Answer: B
Rationale: The correct answer is B: Automated peritoneal dialysis (APD). In APD, the patient connects to a machine at night for dialysis while sleeping, and during the day, the dialysis fluid remains in the abdomen. This allows for continuous treatment without the need for daytime exchanges.
A: Long nocturnal hemodialysis involves nighttime hemodialysis sessions but does not involve leaving fluid in the abdomen during the day.
C: Continuous venovenous hemofiltration is a continuous renal replacement therapy used in critically ill patients, not for ambulatory dialysis.
D: Continuous ambulatory peritoneal dialysis (CAPD) requires manual exchanges throughout the day, unlike APD where the fluid remains in the abdomen during the day.
