Correct Answer: A

Rationale: The correct instruction for a client prescribed glipizide, a sulfonylurea used to lower blood sugar levels, is to take the medication with meals. Taking it with meals helps to minimize the risk of hypoglycemia by ensuring a more balanced effect on blood glucose levels throughout the day. It is important for the client to follow this instruction to maintain stable blood sugar levels and reduce the likelihood of experiencing low blood sugar (hypoglycemia) episodes.

Correct Answer: C

Rationale: The correct insulin type for the nurse to mix into the intravenous fluids is regular insulin. In the scenario of diabetic ketoacidosis (DKA), rapid reduction of blood glucose levels is crucial. Regular insulin has a fast onset of action, making it suitable for intravenous administration to address the high blood sugar levels seen in DKA. Isophane, Glargine, and Detemir are not appropriate choices for intravenous administration in this emergency situation as they are intermediate-acting or long-acting insulins.

Correct Answer: A

Rationale: The correct answer is A: Drowsiness. Fluvoxamine is known to cause drowsiness as a potential side effect. Patients should be advised to avoid activities like driving that require alertness until they understand how the medication affects them. Dry mouth, insomnia, and headache are potential side effects of other medications used for anxiety disorders but are not typically associated with fluvoxamine.

Correct Answer: C

Rationale: It is essential for the nurse to educate the client that healing from erosive esophagitis typically takes several weeks to manage expectations. This information helps the client understand the timeline for improvement and reduces anxiety about the effectiveness of the treatment. It is not necessary to confirm the timing of medication intake, assess bowel sounds, or measure the apical pulse in this scenario. Since symptoms have persisted after one week of lansoprazole, it may not be appropriate to immediately escalate to a higher dose without further assessment or guidance from the healthcare provider.

Correct Answer: B

Rationale: The correct instruction for a client prescribed metformin is to take the medication with a full glass of water. This helps ensure proper ingestion and absorption of the medication. While taking metformin with meals can help reduce gastrointestinal side effects, the primary focus should be on adequate hydration and absorption by taking it with water.
