Correct Answer: B

Rationale: The correct answer is B: Use a soft toothbrush and electric razor. Patients with bone marrow depression are at increased risk of bleeding due to low platelet count. Using a soft toothbrush and electric razor helps prevent injury to the gums and skin, reducing the risk of bleeding. Choices A, C, and D are incorrect because: A: Sleeping with the head of the bed slightly elevated is not directly related to preventing bleeding in bone marrow depression. C: Drinking citrus juices may irritate the stomach lining and are not specifically indicated for preventing bleeding. D: Increasing activity level and frequent ambulation may increase the risk of injury and bleeding in a patient with bone marrow depression.

Correct Answer: C

Rationale: The correct answer is C: Close the roller clamp on the new tubing after priming it. This step ensures that the tubing is primed with the solution and ready for use while preventing air from entering the central line. Option A is incorrect because using the present solution may introduce contamination. Option B is incorrect as connecting tubing before running fluid can introduce air into the line. Option D is incorrect as positioning the client on the right side does not prevent air embolism during tubing change.

Correct Answer: B

Rationale: The correct answer is B: Do not give the antibiotic. This is because the patient has a history of being "very sick" after taking erythromycin in the past, indicating a potential allergic reaction or severe adverse effects. The nurse should not administer the antibiotic to prevent harm to the patient. Choice A is incorrect as it can lead to a repeat adverse reaction. Choice C, giving half the dose, still exposes the patient to potential harm. Choice D, discontinuing the antibiotic, is also incorrect as it implies the patient has already started the medication, which should not be the case given the history of adverse effects.

Correct Answer: B

Rationale: The correct answer is B: Ask the patient to return to the room, so the nurse can inspect the abdomen. Rationale: 1. Patient safety: By examining the patient's abdomen, the nurse can assess for any signs of distress or potential medical issues. 2. Patient-centered care: It is essential to prioritize the patient's well-being by addressing their concerns promptly and appropriately. 3. Professional responsibility: Nurses are trained to assess and evaluate patient symptoms to provide necessary care and support. Summary: A: Requesting the family to leave does not address the patient's symptoms and may disrupt the patient's support system. C: Asking about bowel movements and offering food may not be appropriate if the patient is experiencing stomach discomfort. D: Offering food without proper assessment may worsen the patient's condition and is not recommended before a proper evaluation.

Correct Answer: A

Rationale: The correct answer is A. When someone is extremely confused, providing new information slowly and in small amounts can help prevent overwhelming stress and further confusion. This approach allows the individual to process information more effectively and reduces the risk of escalating confusion or delirium as a defense mechanism. Choices B, C, and D are incorrect because destruction of brain cells, teaching progression, and giving minimal information are not directly related to managing confusion in this scenario.
