1. A client has a new prescription for spironolactone. The client should avoid which of the following foods?

A. Salt substitutes
B. Apples
C. Chicken
D. Bananas

Correct answer: A

Rationale: Spironolactone is a potassium-sparing diuretic. Clients prescribed spironolactone should avoid salt substitutes because they often contain potassium. Increased potassium intake can lead to hyperkalemia, which is a potential side effect of spironolactone.

2. A client has a new prescription for Nitrofurantoin. Which of the following instructions should the nurse include?

A. Take this medication with food.
B. Avoid dairy products while taking this medication.
C. Take this medication at bedtime.
D. Increase your intake of vitamins.

Correct answer: A

Rationale: The correct instruction for a client prescribed Nitrofurantoin is to take the medication with food. Taking Nitrofurantoin with food helps enhance absorption and reduces the risk of gastrointestinal side effects. It is important for the nurse to emphasize this instruction to ensure the client benefits optimally from the medication. Choices B, C, and D are incorrect. Avoiding dairy products is not specifically required with Nitrofurantoin. Taking the medication at bedtime is not a standard instruction. Increasing vitamin intake is not necessary in relation to Nitrofurantoin therapy.

3. Potassium-sparing diuretics primarily affect which part of the kidney?

A. Proximal convoluted tubule
B. Loop of Henle
C. Collecting duct
D. Distal convoluted tubule

Correct answer: D

Rationale: Potassium-sparing diuretics exert their primary effects on the distal convoluted tubule in the kidney. By acting on this specific part of the nephron, these diuretics promote sodium excretion while sparing potassium, thus helping to maintain potassium levels in the body. This mechanism differs from other diuretics that may cause potassium loss as a side effect. Understanding the site of action of potassium-sparing diuretics is crucial in clinical practice for managing conditions like hypertension and edema where diuresis is necessary without the risk of hypokalemia.

4. What is the antidote for copper toxicity?

A. Glucagon
B. Aminocaproic acid
C. Atropine
D. Penicillamine

Correct answer: D

Rationale: Penicillamine is the specific chelating agent used for copper toxicity. It forms stable complexes with copper, which are then excreted in the urine. Glucagon is used for treating hypoglycemia, aminocaproic acid is used to treat bleeding disorders, and atropine is used as an antidote for certain types of poisoning, such as organophosphate toxicity.

5. A client has a prescription for Bethanechol to treat urinary retention. Which of the following findings is a manifestation of muscarinic stimulation?

A. Dry mouth
B. Hypertension
C. Excessive perspiration
D. Fecal impaction

Correct answer: C

Rationale: The correct answer is C: Excessive perspiration. Bethanechol is a muscarinic agonist that stimulates muscarinic receptors. Activation of muscarinic receptors can lead to excessive perspiration (diaphoresis) due to increased cholinergic activity, affecting sweat glands. Dry mouth, hypertension, and fecal impaction are not typically associated with muscarinic stimulation. Dry mouth is more commonly associated with anticholinergic medications, hypertension can be a result of alpha-adrenergic stimulation, and fecal impaction is not a direct effect of muscarinic receptor activation.
