Correct Answer: A

Rationale: In a client with chronic kidney disease experiencing fluid volume overload, the nurse should expect a decreased blood pressure. Fluid volume overload can lead to poor cardiac output, which in turn can cause a decrease in blood pressure. Choices B, C, and D are incorrect. Increased urine output is not expected in fluid volume overload; decreased heart rate is not typically associated with fluid volume overload; and an increased heart rate is more commonly seen in response to fluid overload to compensate for the decreased cardiac output.

Correct Answer: C

Rationale: The correct answer is C: Tachypnea. When caring for a client with pneumonia, the nurse should expect tachypnea, which is rapid breathing. This occurs due to decreased oxygenation and lung function. Bradycardia (A) is not typically associated with pneumonia; instead, tachycardia may be present. Hypertension (B) is not a common manifestation of pneumonia; instead, hypotension may occur due to sepsis. Hypothermia (D) is not a typical finding in pneumonia; fever or an elevated temperature is more common.

Correct Answer: A

Rationale: In this scenario, the nurse should arrange for an ethics committee meeting to address the family's concerns while ensuring the client's wishes are respected. Choosing option A allows for a formal discussion involving healthcare professionals, family members, and possibly a legal expert to navigate the situation ethically and legally. Supporting the family's decision to initiate life-sustaining measures (option B) would disregard the client's advance directives and autonomy. Completing an incident report (option C) is not appropriate in this situation as it does not address the conflict of interest between the family's desires and the client's wishes. Encouraging the family to contact an attorney (option D) may escalate the situation unnecessarily before exploring more ethical and collaborative approaches.

Correct Answer: D

Rationale: The correct answer is D. A low potassium level (3.1 mEq/L) can increase the risk of digoxin toxicity. Hypokalemia can potentiate the effects of digoxin on the heart, leading to serious dysrhythmias. Choices A, B, and C are within normal ranges and do not indicate a need to withhold digoxin.
