1. A client has a new prescription for Digoxin. Which of the following findings should the nurse identify as a potential sign of Digoxin toxicity?

A. Nausea
B. Dry mouth
C. Hypoglycemia
D. Tinnitus

Correct answer: A

Rationale: Nausea is a potential sign of Digoxin toxicity. Other signs of Digoxin toxicity include vomiting, visual disturbances, and confusion. Nausea can be an early indicator of toxicity and should be closely monitored by the nurse. Dry mouth and hypoglycemia are not typically associated with Digoxin toxicity. Tinnitus is more commonly associated with medications like aspirin or loop diuretics, not Digoxin.

2. A nurse is teaching a client who has a new prescription for Hydralazine. Which of the following adverse effects should the nurse instruct the client to monitor?

A. Tachycardia
B. Hyperglycemia
C. Hyponatremia
D. Constipation

Correct answer: A

Rationale: Corrected Rationale: Hydralazine is a vasodilator that can cause reflex tachycardia as an adverse effect. The client should monitor their pulse and report any significant increases. Choice B, Hyperglycemia, is not a common adverse effect of Hydralazine. Choice C, Hyponatremia, and Choice D, Constipation, are also not typically associated with Hydralazine use.

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

A. Brush and floss your teeth regularly.
B. Avoid drinking grapefruit juice.
C. Take this medication with food.
D. Increase your intake of calcium-rich foods.

Correct answer: A

Rationale: The correct answer is to instruct the client to brush and floss their teeth regularly. Phenytoin can lead to gingival hyperplasia, making oral hygiene crucial to prevent complications. Encouraging good oral care practices helps reduce the risk of adverse effects on the gums and teeth. Avoiding grapefruit juice is not specifically related to Phenytoin. While some medications require intake with food, Phenytoin is usually taken on an empty stomach for better absorption. Increasing calcium-rich foods is not directly associated with Phenytoin therapy.

4. Which of the following is not an effect of the drug isoflurane?

A. Elevated lipid levels
B. Nausea
C. Increased blood flow to the brain
D. Decreased respiratory function

Correct answer: A

Rationale: Isoflurane is not known to cause elevated lipid levels. Common effects of isoflurane include nausea, increased blood flow to the brain, and decreased respiratory function. Elevated lipid levels are not typically associated with the administration of isoflurane, making choice A the correct answer.

5. What should a patient avoid while taking Angiotensin-converting enzymes?

A. Salt substitutes
B. Foods high in potassium
C. Foods high in sodium
D. All of the above

Correct answer: A

Rationale: Patients taking Angiotensin-converting enzyme (ACE) inhibitors should avoid salt substitutes because they can contain potassium chloride, which may lead to hyperkalemia. It is important to restrict potassium-rich foods while on ACE inhibitors, but the primary concern with salt substitutes is their potassium content.
