Correct Answer: D

Rationale: In cardiogenic shock, the priority nursing diagnosis is Ineffective Tissue Perfusion. This diagnosis indicates that the client is not receiving adequate oxygenated blood to tissues, putting vital organs at risk. Addressing ineffective tissue perfusion is crucial to prevent organ damage and ensure the client's survival. The other options, such as 'Risk for imbalanced body temperature,' 'Excess fluid volume,' and 'Fatigue,' are important but secondary to the immediate threat of inadequate tissue perfusion in cardiogenic shock.

Correct Answer: B

Rationale: The best action for the nurse-manager to implement is to propose a method for self-staffing labor and delivery. This approach allows nurses to manage their schedules, ensuring a fair balance of workloads. Requiring cross-training for obstetrics for other nurses (Choice A) may not be feasible or necessary for all units. Reminding nurses that floating is an administrative policy (Choice C) does not address the underlying issue of workload balance. Encouraging nurses to share their feelings with administration (Choice D) may not lead to a concrete solution for the unequal floating concerns.

Correct Answer: C

Rationale: Understanding what losses the client recently experienced is crucial for the nurse in developing a therapeutic relationship. This information helps the nurse comprehend the client's emotional state, the potential triggers for the self-harm behavior, and provides insights into the client's current psychological and social challenges. Choice A, the family's reaction, may be important but is secondary to understanding the client's own experiences. Choice B, the nurse's feelings, is not relevant as the focus should be on the client. Choice D, why the client attempted suicide, is important but delving into recent losses can provide a broader context for the client's emotional distress and suicidal behavior.

Correct Answer: D

Rationale: Bilirubin is a key serum laboratory value that is likely to be elevated in clients with jaundice. Jaundice is characterized by a yellowish discoloration of the skin and eyes due to an excess of bilirubin, a breakdown product of hemoglobin. Elevated amylase levels are associated with pancreatic conditions, not specifically jaundice. Creatinine and blood urea nitrogen are markers of kidney function and are not directly related to jaundice.

Correct Answer: A

Rationale: The correct answer is A. Rifampin (Rifadin) commonly causes a reddish-orange discoloration of body fluids, including urine, sweat, saliva, and tears. This is a harmless side effect but should be reported to the healthcare provider for monitoring. Choices B, C, and D are not typically associated with rifampin therapy. Bloody or blood-tinged urine may indicate other issues such as urinary tract infection or kidney problems, blurring of vision may suggest eye problems, and significant weight gain could be related to various health conditions unrelated to rifampin.
