Correct Answer: B

Rationale: The correct answer is B: Drowsiness. Muscle relaxants can cause drowsiness as a common side effect due to their sedative properties. This can impair alertness and coordination, so it's crucial for the patient to be aware of this potential effect. Choice A, hypoglycemia, is not typically associated with muscle relaxants. Choice C, hypotension, is more commonly linked to medications like antihypertensives. Choice D, dyspnea, which is difficulty breathing, is not a common side effect of muscle relaxants. Therefore, the nurse should primarily focus on educating the patient about the potential side effect of drowsiness.

Correct Answer: C

Rationale: The correct answer is C because TPN (Total Parenteral Nutrition) is indeed given to patients with fluid restrictions, as it provides complete nutrition including fluids, electrolytes, and nutrients. On the other hand, PPN (Peripheral Parenteral Nutrition) is used for patients without fluid restrictions as it provides partial nutrition. A is incorrect because TPN is typically for long-term use and PPN for short-term use. B is incorrect as the caloric requirement does not determine the type of parenteral nutrition. D is incorrect because both TPN and PPN can be used for patients who are unable to eat orally.

Correct Answer: C

Rationale: The correct answer is C: Observing for leakage of urine or stool from the anastomosis. This is crucial in nursing management post-urinary diversion procedure to prevent complications such as infection, dehydration, and skin breakdown. Leakage can indicate issues with the surgical site integrity and requires prompt intervention. A: Placement of IV and central venous pressure lines is important but not as critical as monitoring for leakage from the anastomosis. B: Administering cleansing enemas may be necessary for certain procedures but is not the most important factor in this case. D: Assessing the client's ability to manage self-catheterization is important for long-term care but does not take precedence over monitoring for potential complications like leakage. In summary, option C is the most important factor as it directly impacts the client's immediate post-operative care and helps prevent serious complications.

Correct Answer: D

Rationale: The correct answer is D because using two pillows to raise the head can increase the risk of venous stasis and thrombosis in a client with polycythemia vera. This condition involves an increased production of red blood cells, leading to thicker blood and potential clot formation. Elevating the head too much can impede blood flow, exacerbating the risk of clotting. Choices A, B, and C are all appropriate statements indicating good self-care practices and physical activity, which are beneficial for clients with polycythemia vera to improve circulation and overall health.

Correct Answer: D

Rationale: Step 1: Multiple sclerosis (MS) is a progressive disease affecting the central nervous system. Step 2: Axon degeneration occurs in MS, leading to impaired nerve signal transmission. Step 3: MS is characterized by sclerosed patches, or plaques, in the nervous system. Step 4: Demyelination of the brain and spinal cord is a hallmark feature of MS. Step 5: Therefore, all of the above choices are correct as they accurately describe key features of MS.
