Correct Answer: B

Rationale: When a client is prescribed Atenolol, a beta-blocker, they should monitor their heart rate before taking the medication. It is crucial because if the heart rate is below 60 bpm, the client needs to contact their healthcare provider for further guidance and evaluation. Choices A, C, and D are incorrect. Atenolol does not need to be taken with a high-fat meal, does not typically cause a persistent cough, and there is no need to avoid foods high in fiber when taking this medication.

Correct Answer: B

Rationale: The correct action for the nurse to take when a client on methotrexate reports bleeding gums is to check the client's current platelet count. Bleeding gums may indicate thrombocytopenia, a decreased platelet count which can be a severe side effect of methotrexate therapy. Monitoring the platelet count is crucial for early detection and management of this potentially life-threatening complication. Choice A is incorrect as bleeding gums in this context may not be an expected adverse effect of methotrexate. Choice C is irrelevant and does not address the potential underlying issue of thrombocytopenia. Choice D is not the primary action needed at this point; checking the platelet count is more urgent to assess the severity of the situation.

Correct Answer: B

Rationale: The correct instruction for dry mouth associated with diphenhydramine is to chew on sugarless gum or suck on hard, sour candies. These actions stimulate saliva production, providing relief from dry mouth. Administering the medication with food (Choice A) may help reduce stomach upset but won't address dry mouth. Placing a humidifier at the bedside (Choice C) can help with dry air-related issues but won't specifically target dry mouth. Discontinuing the medication (Choice D) without consulting the provider is not recommended and may lead to inadequate treatment of poison ivy.

Correct Answer: C

Rationale: The correct answer is C. Reporting restlessness or involuntary movements is crucial as they can be signs of extrapyramidal symptoms, a potential side effect of Metoclopramide. These symptoms should be reported promptly to the healthcare provider for appropriate management. Choices A, B, and D are incorrect because taking the medication before bedtime, discontinuing it due to drowsiness, or expecting urine color changes are not relevant teaching points for Metoclopramide use.

Correct Answer: B

Rationale: Montelukast should be taken daily in the evening to effectively manage asthma symptoms. Taking it at the same time each day helps maintain a consistent level of the medication in the body, providing optimal control over asthma symptoms and inflammation. Choice A is incorrect because Montelukast should not be taken specifically before exercise, but rather daily. Choice C is incorrect because although taking Montelukast two hours before exercise is not necessary, taking it daily in the evening is essential for its effectiveness. Choice D is incorrect as Montelukast should be taken daily to manage asthma.
