When administering a nasal spray medication, what should the client do before the medication is administered?

Correct Answer: A

Rationale: The correct answer is that the client should blow their nose gently before the medication is administered. This step helps clear the nasal passages, ensuring that the medication can reach its intended target. Choice B is incorrect as the nasal spray should be directed into the nostril, not just in front of the nose. Administering the medication as the client inhales (Choice C) is crucial to ensure proper delivery, as it helps the medication reach the desired areas. Choice D is incorrect because the client should be sitting upright, not lying flat, when administering nasal spray medication to allow for better absorption and prevent the medication from flowing out.

Correct Answer: B

Rationale: The therapeutic range for carbamazepine (Tegretol) is 4-10 mcg/mL. This range is established based on the optimal balance between effectiveness and safety. Choices A, C, and D are outside the therapeutic range for carbamazepine, which could lead to suboptimal treatment outcomes or increased risk of toxicity. Choice B (4-10 mcg/mL) is the correct range recommended for therapeutic efficacy while minimizing adverse effects.

Correct Answer: B

Rationale: The correct answer is grapefruit. Clients taking MAO Inhibitors like phenelzine (Nardil) should avoid foods rich in tyramine to prevent hypertensive crisis. Grapefruit is a suitable choice as it is not high in tyramine. Bananas, avocados, and salami are foods that should be avoided due to their tyramine content, which can interact adversely with MAO Inhibitors. Therefore, choosing grapefruit is the safest option for the client.

Correct Answer: B

Rationale: The correct answer is 'headache.' While vancomycin can cause ototoxicity leading to symptoms like tinnitus, vertigo, and nausea, headaches are not typically associated with vancomycin use. Therefore, headache is the least concerning symptom in this scenario. Nausea, vertigo, and tinnitus are more likely to be related to vancomycin ototoxicity and should be closely monitored and reported. Headache is a common symptom that may not be directly linked to vancomycin use.

Correct Answer: B

Rationale: Acetaminophen is extensively metabolized in the liver. An overdose of acetaminophen can lead to severe liver damage and even liver failure, which can be life-threatening. Choices A, C, and D are incorrect because although prolonged use of acetaminophen may lead to an increased risk of renal dysfunction, a single overdose does not typically cause life-threatening abnormalities in the lungs, kidneys, or adrenal glands.
