Correct Answer: A

Rationale: The correct answer is A: Bleeding precautions. With low platelets (50,000/ul), the client is at risk for bleeding. Platelets help with blood clotting, so precautions to prevent bleeding are essential. This includes avoiding activities that can cause injury, using a soft toothbrush, and reporting any signs of bleeding. Summary: B: Isolation to prevent infection - This is not related to the client's lab values. C: Seizure precautions - Not relevant to the client's lab values. D: Control of pain with analgesics - Pain management is not the priority given the client's lab values indicating a risk of bleeding.

Correct Answer: B

Rationale: The correct answer is B: soften the fecal mass and lubricate the walls of the rectum and colon. First, the oil retention enema helps soften the fecal mass, making it easier to pass. Second, the oil lubricates the walls of the rectum and colon, reducing friction and making the passage of stool smoother. This helps prepare the fecal impaction for removal during the subsequent cleansing enema. Choices A, C, and D are incorrect because they do not directly address the primary goal of softening the fecal mass and lubricating the walls of the intestines to facilitate the removal of the impaction.

Correct Answer: B

Rationale: The correct answer is B: Increased urine osmolarity. In hyperglycemia, the body tries to eliminate excess glucose through increased urine output, causing a concentrated urine with high osmolarity. This indicates fluid deficit. Cool, clammy skin (A) may suggest poor perfusion but not fluid volume deficit. Distended neck veins (C) are more indicative of fluid overload. Serum sodium level (D) may be elevated in fluid deficit but does not directly assess volume status like urine osmolarity does.

Correct Answer: C

Rationale: The correct answer is C because older clients with AIDS have a faster progression of the disease due to age-related changes in the immune system, making them more vulnerable to complications. This results in a greater need for care compared to younger counterparts. Choice A is incorrect as lack of balanced diet and activity does not directly relate to the progression of AIDS. Choice B is incorrect as knowledge about disorders is not the main factor affecting the level of care needed. Choice D is incorrect as adherence to therapy is important but not the main reason older clients need more care.

Correct Answer: D

Rationale: The correct answer is D: Reassess the patient. During the initial phase of implementation, the nurse should first reassess the patient to gather current data and evaluate the effectiveness of previous interventions. This step ensures that the nurse has updated information to make informed decisions about the patient's care. A: Determining patient outcomes and goals should come after reassessment. B: Prioritizing nursing diagnoses is important but should be based on current assessment data. C: Evaluating interventions should be done after implementing them and giving them time to take effect.
