Correct Answer: C

Rationale: Before transporting the client for whirlpool therapy to debride the burned area, the nurse should give a prescribed narcotic analgesic agent. This intervention is essential to manage pain effectively during the debridement process. Obtaining supplies to re-dress the burn area (Choice A) is important but not as immediate as providing pain relief. Verifying the client's signed consent form (Choice B) is necessary for procedures but does not address the client's immediate pain needs. Performing active range-of-motion exercises (Choice D) is not indicated before whirlpool therapy for debridement of burns and may cause further discomfort to the client.

Correct Answer: B

Rationale: The correct answer is to ask the client to describe the pain. This approach allows the nurse to gather subjective information directly from the client, such as the quality, intensity, location, and factors that aggravate or alleviate the pain. Observing body language and movement (Choice A) can provide additional cues but may not fully capture the client's pain experience. Identifying effective pain relief measures (Choice C) and providing a numeric pain scale (Choice D) are important aspects of pain management but do not directly assess the quality of the client's pain.

Correct Answer: C

Rationale: In chronic pancreatitis, managing abdominal pain is crucial, and assessing the client's eating patterns and dietary intake is essential. Dietary modifications can help alleviate symptoms and reduce the workload on the pancreas. Choices A, B, and D are not directly related to pain management in chronic pancreatitis. Bowel sounds, fecal characteristics, and physical activity may provide important information in other conditions but are not the priority in this scenario.

Correct Answer: D

Rationale: The expected increase in hematocrit after transfusion is approximately 3% per unit of PRBCs. Since the client received 4 units, the expected increase would be 4 x 3% = 12%. Therefore, adding this to the pretransfusion hematocrit of 17% would result in an expected post-transfusion hematocrit of 29%. Choice A (0.19) is incorrect as it doesn't consider the incremental increase per unit of PRBCs. Choices B (0.09) and C (0.39) are also incorrect as they do not align with the expected increase in hematocrit following the transfusion of 4 units of PRBCs.

Correct Answer: B

Rationale: In chronic kidney disease, hyperkalemia is the most common electrolyte imbalance due to the kidneys' reduced ability to excrete potassium. This impaired kidney function leads to potassium retention in the body, resulting in elevated serum potassium levels. Hypernatremia (increased sodium levels) is less likely in chronic kidney disease as the kidneys typically still function to regulate sodium levels. Hypocalcemia (low calcium levels) is not a prominent electrolyte imbalance in chronic kidney disease unless there are additional factors involved. Hypokalemia (low potassium levels) is less common in chronic kidney disease, as the primary issue is usually potassium retention rather than deficiency.
