Correct Answer: B

Rationale: The correct statement the nurse should include is that the client may experience weight gain while taking fluoxetine. Weight gain is a common side effect of fluoxetine, and patients should be informed about this potential issue. Stating that the client should expect improvement in symptoms within 1 week (Choice A) is incorrect as fluoxetine may take a few weeks to have a noticeable effect. Taking the medication in the morning to prevent insomnia (Choice C) is not necessary since fluoxetine can be taken at any time of the day. Instructing the client to stop taking the medication if experiencing dry mouth (Choice D) is misleading, as dry mouth is a common but usually not serious side effect of fluoxetine.

Correct Answer: D

Rationale: Verifying the pH of the gastric aspirate is the correct action to take before administering an intermittent enteral feeding through an NG tube. This step ensures proper tube placement in the stomach, as the gastric aspirate should have an acidic pH (usually below 5). Heating the feeding solution, elevating the head of the bed, or flushing the tube with saline are not directly related to verifying tube placement and are not the immediate actions needed before administering the feeding.

Correct Answer: C

Rationale: The correct answer is to check the oxygen level regularly using a pulse oximeter. This instruction is crucial as it ensures safe and adequate oxygenation for the client. Option A is incorrect as oxygen should not be stored in a storage room but in a well-ventilated area. Option B is not ideal as oxygen should be left on unless otherwise specified by a healthcare provider. Option D is also important but not directly related to the primary instruction of monitoring oxygen levels.

Correct Answer: B

Rationale: Shoulder presentation is a contraindication for oxytocin because it can increase the risk of complications during labor, such as shoulder dystocia. Diabetes mellitus (Choice A) is not a contraindication for the use of oxytocin. Postterm with oligohydramnios (Choice C) and chorioamnionitis (Choice D) may actually necessitate the use of oxytocin to induce or augment labor for the well-being of the mother and baby.

Correct Answer: D

Rationale: The correct answer is D: 'Monitor for signs of infection.' Clopidogrel affects platelet levels, increasing the risk of bleeding. Therefore, it is essential for clients taking clopidogrel to monitor for signs of infection, which could indicate a lowered immune response. Choices A, B, and C are incorrect because they do not directly relate to the specific monitoring needs associated with clopidogrel therapy.
