A nurses colleague has applied an incontinence pad Select all that apply.
- A. Dietary history
- B. What principle
- C. Family history of renal stones
- D. Medication history
Correct Answer: A
Rationale: The correct answer is A: Dietary history. Understanding the patient's dietary habits can help identify potential triggers for incontinence, such as caffeine or alcohol intake. It also provides insight into fluid intake, which can impact incontinence.
Incorrect choices:
B: What principle - This is vague and does not provide relevant information for managing incontinence.
C: Family history of renal stones - While family history can be important for certain conditions, it is not directly related to managing incontinence.
D: Medication history - While medications can sometimes contribute to incontinence, dietary factors are typically more significant in this context.

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.
A function of the kidney is to
- A. produce angiotensin
- B. remove microorganisms from the blood
- C. remove aged blood from the blood
- D. regulate blood ionic composition
Correct Answer: D
Rationale: The correct answer is D: regulate blood ionic composition. The kidneys help maintain the body's electrolyte balance by regulating the levels of ions such as sodium, potassium, and calcium in the blood. This is crucial for proper nerve and muscle function, pH balance, and overall homeostasis.
Explanation for why the other choices are incorrect:
A: The production of angiotensin is primarily done by the liver and lungs, not the kidneys.
B: While the kidneys help filter out waste and toxins, they do not specifically target microorganisms in the blood.
C: Removing aged blood from the blood is not a function of the kidneys; this task is mainly carried out by the spleen and liver.
In summary, the kidney's main function is to regulate blood ionic composition to maintain overall bodily functions, making choice D the correct answer.
Which of the following statements about part of a nephron? antidiuretic hormone (ADH) is incorrect?
- A. renal pelvis
- B. ADH regulates the amount of water
- C. distal tubule reabsorbed by the kidneys
- D. collecting duct
Correct Answer:
Rationale: The correct answer is A: renal pelvis. The renal pelvis is not directly related to the action of antidiuretic hormone (ADH) in the nephron. ADH regulates water reabsorption in the collecting duct of the nephron to maintain water balance in the body. Choices B, C, and D are incorrect because they are all associated with the function of ADH in the nephron. ADH regulates the amount of water reabsorbed in the distal tubule and collecting duct, not the renal pelvis.
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.
Antiviral agents that is/ are active against cytomegalovirus (CMV) include which of the following?
- A. Ganciclovir
- B. Foscarnet
- C. Acyclovir
- D. (a) and (b) are correct
Correct Answer: D
Rationale: The correct answer is D because both Ganciclovir and Foscarnet are active against cytomegalovirus (CMV). Ganciclovir works by inhibiting viral DNA polymerase, while Foscarnet inhibits viral DNA polymerase and reverse transcriptase. Acyclovir, on the other hand, is not effective against CMV as it primarily targets herpes simplex virus and varicella-zoster virus. Therefore, choices A and B are correct for CMV treatment, making option D the correct answer.
