Correct Answer: C

Rationale: The correct answer is C: Your doctor might need to reduce your theophylline dose while taking this medication. Cimetidine can interact with theophylline, leading to increased theophylline levels in the blood, which can be harmful.
Therefore, the nurse should include this instruction to ensure the client's safety.

Explanation for other choices:
A: Take the medication on an empty stomach for better absorption - This is not necessary for cimetidine; it can be taken with or without food.
B: You should plan to take this medication for at least 6 months - Duration of therapy varies and should be determined by the healthcare provider.
D: Take the medication with an antacid to minimize stomach upset - Cimetidine itself is an antacid, so taking it with another antacid is not recommended.

Correct Answer: B

Rationale: The correct answer is B: Administer the medication over 1 min. This is important to prevent adverse effects such as hypotension and cardiac arrhythmias, which can occur if phenytoin is administered too rapidly. Diluting the medication with sterile water (
Choice
A) is not necessary as the medication is already in a concentration suitable for IV administration. Following the IV injection with sterile water (
Choice
C) is not a standard practice and may not provide any additional benefit. Slowing the injection if the medication crystallizes (
Choice
D) is incorrect because if the medication crystallizes, it should not be used and the nurse should obtain a new vial.

Correct Answer: C

Rationale: The correct answer is C: Tinnitus. Cisplatin, a chemotherapy drug, is known to cause ototoxicity, including tinnitus, which is a ringing in the ears. Tinnitus is an adverse effect that the nurse should include in the teaching because it can impact the client's quality of life. Constipation (
A) is not a common adverse effect of cisplatin. Weight gain (
B) is also not a typical adverse effect associated with cisplatin; in fact, weight loss is more common. Hyperkalemia (
D) is not a known adverse effect of cisplatin.
Therefore, the nurse should focus on educating the client about tinnitus when discussing the adverse effects of cisplatin.

Correct Answer: D

Rationale: The correct answer is D: Take the missed dose now, then continue the medication as ordered. The rationale for this is to ensure contraceptive efficacy. In the first week of the pack, missing a single dose can decrease the effectiveness of the contraceptive. By taking the missed dose as soon as possible and continuing with the regular schedule, the client minimizes the risk of ovulation and unintended pregnancy.
Choice A is incorrect as abruptly stopping the pills can lead to contraceptive failure.
Choice B is unnecessary at this point as the focus should be on contraceptive management.
Choice C is not a practical solution as missing one pill does not warrant avoiding intercourse for an entire cycle.

Correct Answer: B

Rationale: The correct answer is B: Decreased auditory hallucinations. Olanzapine is an antipsychotic medication used to treat symptoms of schizophrenia and bipolar disorder. It works by blocking dopamine and serotonin receptors in the brain, which helps reduce hallucinations. Monitoring for a decrease in auditory hallucinations is important as it indicates that the medication is working effectively.

Choices A, C, and D are incorrect because olanzapine is not typically associated with a decrease in resting blood pressure, control of seizure activity, or increased energy level. It is important for the nurse to focus on monitoring the client's response to the medication and address any side effects or adverse reactions that may occur.
