Correct Answer: A

Rationale: Step 1: Respect and compassion are essential in end-of-life care to support patients emotionally. Step 2: Nurses need to show empathy and understanding towards patients and their families. Step 3: Providing comfort and dignity in the final stages of life is crucial. Step 4: Assessing and intervening (Choice B) is important but not the primary competency in end-of-life care. Step 5: Setting goals and dynamic changes to care (Choice C) may be relevant but not as fundamental as respect and compassion. Step 6: Keeping sad news away (Choice D) goes against transparency and trust-building in end-of-life care.

Correct Answer: C

Rationale: The correct intervention for hyperkalemia is to administer insulin (Choice C). Insulin drives potassium into cells, lowering serum potassium levels. This is effective in acutely reducing high potassium levels. Administering calcium gluconate (Choice A) is used for stabilizing cardiac membranes in hyperkalemia but does not lower potassium levels. Sodium bicarbonate (Choice B) is used for metabolic acidosis, not hyperkalemia. Furosemide (Choice D) is a loop diuretic that can lead to potassium loss but is not the primary intervention for hyperkalemia.

Correct Answer: B

Rationale: The correct assessment is B because providing consistent information indicates reliability. Drug abuse history (A) does not necessarily mean the patient is unreliable. Smiling (C) is not a reliable indicator. Refusal to answer specific questions (D) does not negate overall reliability.

Correct Answer: D

Rationale: The correct answer is D: Both B and C. After knee replacement surgery, patients are at risk for developing DVT and pulmonary embolism due to immobility and surgery-related factors. DVT occurs when a blood clot forms in a deep vein, usually in the legs, which can lead to a pulmonary embolism if the clot travels to the lungs. Monitoring for both complications is crucial to prevent serious consequences. Option A, hyperglycemia, is not a common complication following knee replacement surgery and is not directly related to immobility or surgery. Option B, DVT, is correct but does not encompass the risk of pulmonary embolism. Option C, pulmonary embolism, is correct but does not cover the initial risk of DVT formation. Therefore, monitoring for both DVT and pulmonary embolism is essential in post-operative knee replacement patients.

Correct Answer: A

Rationale: The correct answer is A: Body systems. This type of assessment promotes critical thinking by organizing data systematically based on different body systems, allowing for clustering of similar data and identification of patterns. Comprehensive assessments (B) may include body systems but lack the focused approach of promoting critical thinking. Head to toe assessments (C) are systematic but may not encourage clustering of data. Emergency assessments (D) prioritize immediate interventions rather than promoting critical thinking or clustering of data.
