1. A client has a new prescription for Metronidazole. Which of the following instructions should be included?

A. Avoid drinking alcohol while taking this medication.
B. Take the medication on an empty stomach.
C. Increase your intake of green, leafy vegetables.
D. Discontinue the medication if you experience a metallic taste.

Correct answer: A

Rationale: The correct instruction for a client prescribed Metronidazole is to avoid drinking alcohol while taking this medication. Metronidazole can cause a disulfiram-like reaction when combined with alcohol, resulting in severe nausea, vomiting, and other adverse effects. Therefore, it is crucial for clients to refrain from consuming alcohol during treatment to prevent these potential complications. Choice B is incorrect because Metronidazole can be taken with or without food. Choice C is irrelevant as there is no specific requirement to increase green, leafy vegetable intake with Metronidazole. Choice D is incorrect as a metallic taste is a known side effect of Metronidazole but does not necessarily indicate the need to discontinue the medication.

2. What are the Therapeutic Effects of Lithium?

A. Prevents or decreases the incidence of acute manic episodes
B. Maintenance of blood glucose
C. Control of hyperglycemia in diabetic patients
D. Diminished seizure activity

Correct answer: A

Rationale: The therapeutic effect of lithium is that it prevents or decreases the incidence of acute manic episodes in patients with bipolar disorder. Lithium is commonly used as a mood stabilizer in the treatment of bipolar disorder due to its ability to reduce the frequency and severity of manic episodes. Choices B, C, and D are incorrect as lithium is not used for the maintenance of blood glucose, control of hyperglycemia in diabetic patients, or to diminish seizure activity. These effects are not associated with the use of lithium as a medication.

3. 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.

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

A. Increase your intake of bran fiber.
B. Monitor your heart rate before taking the medication.
C. Take the medication with antacids.
D. Avoid drinking orange juice.

Correct answer: B

Rationale: When a client is prescribed Digoxin, it is essential to monitor their heart rate before each dose. Changes such as a heart rate below 60 bpm should be reported to the healthcare provider promptly. This is crucial because Digoxin can affect heart rhythm, and monitoring the heart rate helps in identifying any potential issues early on.

5. What is the therapeutic action of Phenytoin?

A. Antidiabetic
B. Anticonvulsant
C. Mood stabilizer
D. Antianxiety agent

Correct answer: B

Rationale: Phenytoin is primarily used as an anticonvulsant to prevent and control seizures. It works by stabilizing electrical activity in the brain, making it effective in managing conditions like epilepsy. Antidiabetic medications are used to regulate blood sugar levels, mood stabilizers help manage mood disorders, and antianxiety agents are used to reduce anxiety symptoms, none of which are the primary therapeutic action of Phenytoin.
