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: C

Rationale: The correct statement is that Brachytherapy is an internal radiation therapy. Brachytherapy involves placing radioactive sources inside or near the tumor, delivering a high radiation dose to the targeted area while minimizing exposure to surrounding healthy tissues. Choices A and B are incorrect because pregnant nurses should not administer radiation therapy and brachytherapy does not make the patient radioactive. Choice D is incorrect as feces is not a source of radiation in teletherapy, and it does not require special disposal.

Correct Answer: C

Rationale: The correct choice is 'Baked apricot chicken and steamed broccoli' because fruits and vegetables have been shown to reduce the risk of cancer. Option A, smoked salmon and green beans, although a healthy choice, does not incorporate as many cancer-fighting foods as the correct answer. Option B, pork chops and fried green tomatoes, contains fried food which is associated with increased cancer risk. Option D, liver, onions, and steamed peas, includes organ meats which are not considered beneficial for reducing cancer risk.

Correct Answer: B

Rationale: The most appropriate response for a patient presenting with a firm, painless cervical lymph node and denying recent infectious diseases is to promptly refer the patient for medical assessment. This is crucial to rule out serious underlying conditions such as malignancy or other concerning causes. Calling 911 is not necessary in this situation as it is not an emergency. Ordering a radiograph may not be the most immediate or appropriate action, as further evaluation by a healthcare provider is needed first. Encouraging the patient to wait and track the lymph node for a week is not advisable when a potential serious condition needs to be ruled out promptly.

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.
