Correct Answer: D

Rationale: The course of polycythemia vera can be best ascertained by monitoring the patient's hematocrit, which should remain below 45%. Hematocrit levels are a key indicator in assessing the progression of the disease. Choices A, B, and C are not the most appropriate methods for gauging the course of polycythemia vera. Monitoring the color of the patient's palms and face, or their response to erythropoietin injections, may not provide an accurate reflection of the disease's progression. Similarly, while erythrocyte sedimentation rate can be affected in polycythemia vera, it is not the primary marker for monitoring the disease's course.

Correct Answer: D

Rationale: The correct answer is to elevate the affected arm. Elevating the affected arm helps prevent lymphedema after a mastectomy. Choices A, B, and C are incorrect. 'Dangling arms at the bedside' does not provide any benefit after a mastectomy. 'Lying down on the affected chest' can cause discomfort and possible complications. 'Drinking plenty of fluids immediately after surgery' is not related to preventing lymphedema post-mastectomy.

Correct Answer: A

Rationale: The correct answer is A because enemas can cause injury to a thrombocytopenic client due to the risk of bleeding. Choices B, C, and D are correct precautions for a client with thrombocytopenia. Using an electric shaver reduces the risk of cuts that could lead to bleeding. Eating soft, cool, or warm food helps prevent injuries to the oral mucosa. Avoiding activities like sports that carry a risk of injury is also advisable.

Correct Answer: A

Rationale: The correct action for the nurse to take when observing swelling and pain at the IV site during the administration of doxorubicin hydrochloride is to stop the administration of the drug immediately. Doxorubicin hydrochloride can cause severe tissue damage, so discontinuing the infusion is crucial to prevent further harm to the patient. Notifying the physician is important, but it should not take precedence over stopping the drug. Continuing the infusion, even at a decreased rate, can exacerbate tissue damage. Applying a warm compress is not appropriate in this situation and may worsen the tissue injury caused by the drug.

Correct Answer: A

Rationale: Clients are often overwhelmed by a sudden cancer diagnosis; therefore, it is best for the nurse to call the client at home the next day to review teaching. This approach allows the client time to process the information before the surgery. Choice B may be beneficial but is not the priority at this time. Providing written instructions (Choice C) is helpful but does not offer the personalized interaction needed. Reassuring the client (Choice D) is important but does not address the educational aspect of preoperative preparation.
