Correct Answer: B

Rationale: The correct answer is B: Hemoglobin levels. Ferrous sulfate is used to treat iron deficiency anemia by increasing the body's iron stores. Monitoring hemoglobin levels is crucial as it reflects the effectiveness of the treatment in improving the client's anemia. Serum potassium levels (Choice A) are typically not directly affected by ferrous sulfate. Liver function tests (Choice C) and blood glucose levels (Choice D) are not routinely monitored when a client is receiving ferrous sulfate unless there are specific indications or pre-existing conditions that warrant such monitoring.

Correct Answer: A

Rationale: The correct answer is A: 'It can cause drowsiness.' Gabapentin is known to cause drowsiness, and clients should be warned about this side effect. Choice B is incorrect because gabapentin, like any medication, can have side effects. Choice C is incorrect because although gabapentin is used for pain management, it is not classified as a pain reliever. Choice D is incorrect because gabapentin should be taken as prescribed by the healthcare provider, and specific instructions regarding food intake should be provided based on individual needs.

Correct Answer: A

Rationale: When administering sertraline, assessing blood pressure is crucial as this medication can potentially affect blood pressure levels. Monitoring blood pressure before giving sertraline helps ensure patient safety and allows for appropriate interventions if any significant changes are noted. Heart rate, respiratory rate, and mood changes are important assessments but are not typically the first priority when administering sertraline. While heart rate and respiratory rate can also be affected by sertraline, blood pressure assessment is a higher priority due to the medication's known effects on blood pressure regulation.

Correct Answer: B

Rationale: Encouraging the patient to express their thoughts is the best response in this situation. It allows the patient to voice their concerns or reasons for canceling the surgery, which can help the healthcare team address any misunderstandings or fears the patient may have. Choices A and D are too directive and do not consider the patient's autonomy and right to make informed decisions about their care. Choice C is inappropriate as it disregards the patient's expressed decision and fails to address the underlying issue.

Correct Answer: B

Rationale: The correct answer is B: Client's vaccination history. Before administering the hepatitis B vaccine, it is essential to verify the client's vaccination history to ensure they are due for the vaccine. This helps in preventing unnecessary vaccinations and ensures the appropriate timing and dosage. Option A, the client's allergy to eggs, is not directly related to administering the hepatitis B vaccine. Option C, the client's weight, and option D, the client's blood pressure, are not factors that need to be specifically verified before administering the hepatitis B vaccine.
