A client is prescribed nitroglycerin sublingual tablets. The practical nurse should reinforce which instruction?

Correct Answer: A

Rationale: Nitroglycerin sublingual tablets are sensitive to heat and moisture, so they should be stored in a cool, dry place to maintain their efficacy. Choice B is incorrect because nitroglycerin tablets should be taken as directed by the healthcare provider. Choice C is incorrect because sublingual tablets should be placed under the tongue to dissolve, not swallowed. Choice D is incorrect because sublingual tablets should not be chewed; they are meant to be absorbed through the tissues under the tongue.

Correct Answer: A

Rationale: Bradycardia is a common sign of digoxin toxicity. Digoxin, a medication used to treat atrial fibrillation, can lead to toxicity manifesting as various cardiac dysrhythmias, with bradycardia being a notable indicator. Monitoring for bradycardia is crucial as it can indicate the need for dosage adjustment or discontinuation of digoxin to prevent adverse effects.

Correct Answer: A

Rationale: The correct instruction for a client with GERD prescribed omeprazole is to take the medication in the morning before breakfast. Omeprazole works best when taken on an empty stomach, approximately 30 minutes before the first meal of the day. This timing maximizes its effectiveness in reducing stomach acid production and helps manage symptoms of GERD more efficiently.

Correct Answer: C

Rationale: In the context of diabetes mellitus type 1, insulin glargine is a long-acting basal insulin that provides a steady level of insulin over a 24-hour period. This makes it most effective when administered at bedtime. By instructing the client to administer insulin glargine at bedtime, the nurse ensures that the medication's peak action aligns with the body's natural overnight fasting state, helping to control blood glucose levels during this crucial period. Option A (Before meals) is incorrect because insulin glargine is not a rapid-acting insulin intended to cover mealtime blood sugar elevations. Option B (After meals) is also incorrect as insulin glargine is not meant to be taken in response to mealtime glucose spikes. Option D (In the morning) is not ideal as it may not provide adequate coverage during the night when blood glucose levels can fluctuate due to the lack of food intake. Educationally, understanding the timing and action of different types of insulin is crucial for managing diabetes effectively. By grasping the pharmacokinetics of insulin glargine, nurses can help clients achieve better glycemic control and reduce the risk of complications associated with diabetes. This knowledge empowers nurses to educate clients on the optimal use of their medications, leading to improved self-management and overall health outcomes.

Correct Answer: A

Rationale: The correct answer is A: Dry mouth. Tiotropium, a commonly prescribed medication for COPD, can cause dry mouth as a side effect. While it may not be severe, clients should report it if it becomes bothersome. Blurred vision, nausea, and tachycardia are not typically associated with tiotropium use in the context of COPD.
