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

A. Avoid drinking grapefruit juice.
B. Take this medication with a full glass of water.
C. Take this medication on an empty stomach.
D. Monitor for signs of dehydration.

Correct answer: D

Rationale: The correct instruction for a client prescribed Losartan is to monitor for signs of dehydration. Losartan can lead to dehydration, so it is essential for the client to be vigilant for symptoms such as dry mouth, increased thirst, and decreased urine output. Providing the instruction to monitor for signs of dehydration ensures the client's safety and helps in early identification of any potential issues related to dehydration. Choices A, B, and C are incorrect as Losartan does not interact with grapefruit juice, does not require specific instructions regarding water intake, and does not need to be taken on an empty stomach.

2. What is the pharmacological class of Lithium?

A. Antidiabetics, biguanides
B. Mood stabilizers
C. Antiarrhythmics, anticonvulsants
D. Vascular headache suppressants

Correct answer: B

Rationale: Lithium is classified as a mood stabilizer due to its primary use in managing bipolar disorder, where it helps stabilize mood swings and prevent episodes of mania and depression. While it can have other effects on the body, its main therapeutic role lies in its mood-stabilizing properties. Choices A, C, and D are incorrect as lithium is not classified as antidiabetics, biguanides, antiarrhythmics, anticonvulsants, or vascular headache suppressants. Its main pharmacological class is mood stabilizers.

3. A client is prescribed an IM dose of penicillin. The client reports developing a rash after taking penicillin 3 years ago. What should the nurse do?

A. Administer the prescribed dose.
B. Withhold the medication.
C. Ask the provider to change the prescription to an oral form.
D. Administer an oral antihistamine at the same time.

Correct answer: B

Rationale: The nurse should withhold the medication and inform the provider of the client's previous rash after taking penicillin. This history suggests a potential allergic reaction to penicillin, which can range from mild to severe anaphylaxis. Notifying the provider allows for an alternative antibiotic to be prescribed, considering the client's allergy to penicillin. It is crucial to avoid administering a medication that could potentially lead to a severe allergic reaction in the client. Administering the prescribed dose (Choice A) could be harmful due to the potential for an allergic reaction. Changing the prescription to an oral form (Choice C) does not address the underlying issue of a potential penicillin allergy. Administering an oral antihistamine (Choice D) without consulting the provider may not be sufficient to prevent a severe allergic reaction.

4. How do ACE inhibitors work?

A. Block the vasoconstrictor and aldosterone effects of angiotensin II at the receptor site
B. Block stimulation of beta 1 and beta 2 at the receptor sites
C. Block the conversion of angiotensin I to the vasoconstrictor angiotensin II
D. None of the above

Correct answer: C

Rationale: ACE inhibitors work by inhibiting the conversion of angiotensin I to angiotensin II. Angiotensin II is a potent vasoconstrictor, and by blocking its production, ACE inhibitors help dilate blood vessels, reduce blood pressure, and decrease the workload of the heart. Choice A is incorrect because it describes the mechanism of action of angiotensin receptor blockers (ARBs), not ACE inhibitors. Choice B is incorrect as it describes beta-blockers, not ACE inhibitors. Choice D is incorrect as ACE inhibitors do have a specific mechanism of action.

5. A healthcare provider is providing teaching to a client who has a new prescription for metronidazole. The healthcare provider should instruct the client to avoid which of the following?

A. Dairy products
B. Alcohol
C. Leafy green vegetables
D. Grapefruit juice

Correct answer: B

Rationale: The correct answer is B: Alcohol. Clients should avoid alcohol while taking metronidazole due to the risk of a disulfiram-like reaction. This reaction can cause symptoms like flushing, headache, nausea, and vomiting when alcohol is consumed while on metronidazole. Dairy products, leafy green vegetables, and grapefruit juice do not have significant interactions with metronidazole. Dairy products do not interfere with metronidazole absorption; leafy green vegetables are safe to consume as they do not affect metronidazole metabolism, and grapefruit juice is not contraindicated with metronidazole.
