Correct Answer: B

Rationale: Assessing the client's respiratory status is the priority as it helps determine if the weight gain is due to fluid retention affecting breathing. This assessment is crucial in addressing the immediate concern of potential respiratory distress before implementing interventions like fluid restriction, diuretics, or notifying the healthcare provider.

Correct Answer: B

Rationale: For clients on heparin therapy, a PTT value of 1.5 to 2.5 times the normal range is required to ensure therapeutic anticoagulation. The normal PTT range is 25 to 35 seconds. In this case, the client's PTT of 25 seconds falls below the therapeutic range, indicating that the heparin dose is insufficient. Therefore, the nurse should anticipate increasing the heparin rate to achieve the desired therapeutic effect.

Correct Answer: C

Rationale: Assessing for chest pain is crucial in post-MI clients as it can indicate complications such as reinfarction or ischemia.

Correct Answer: C

Rationale: The most likely action by the nurse that would have prevented the negative outcome is providing more appropriate supervision of the UAP. Supervision is essential in delegation as it involves directing, evaluating, and following up on delegated tasks. By providing adequate supervision, the nurse can ensure that tasks are performed correctly and promptly identify any issues or abnormalities, such as a significant change in vital signs or the client's mental status. This proactive approach can help prevent adverse outcomes and enhance patient safety.

Correct Answer: C

Rationale: For a client with cirrhosis experiencing ascites, the nurse should instruct them to consume a low-sodium diet. This dietary modification helps reduce fluid retention and manage ascites by decreasing the amount of sodium in the body, which helps prevent fluid accumulation in the abdomen. Limiting sodium intake is crucial in managing ascites and preventing further complications in clients with cirrhosis.
