Correct Answer: B

Rationale: In this situation, the healthcare provider should first check for kinks in the tubing and raise the IV pole. These are common causes of a slowed IV rate and should be addressed before considering other interventions.

Correct Answer: C

Rationale: Pursed-lip breathing is used to increase the amount of carbon dioxide exhaled (C) in clients with chronic obstructive pulmonary disease (COPD). By doing so, it helps prevent air trapping and enhances gas exchange, ultimately improving respiratory efficiency. While removing secretions (A), reducing air trapping (B), and slowing the respiratory rate (D) can be associated benefits, the primary goal of pursed-lip breathing is to optimize carbon dioxide elimination and enhance breathing mechanics.

Correct Answer: B

Rationale: Limiting sodium intake to 2 grams per day (B) is a crucial dietary instruction for clients with heart failure. It helps manage fluid retention and reduces the workload on the heart. Increasing fluid intake (A), avoiding potassium (C), and increasing protein intake (D) are not appropriate dietary instructions for heart failure management.

Correct Answer: A

Rationale: Epigastric pain that radiates to the back (A) is the hallmark assessment finding of acute pancreatitis. The pancreas lies retroperitoneally in the upper abdomen, so inflammation often causes severe epigastric pain that radiates through to the back. Abdominal pain with guarding (B), nausea and vomiting (C), and increased bowel sounds (D) can also be present in acute pancreatitis but are less specific and may be seen in various other gastrointestinal conditions.

Correct Answer: B

Rationale: In this situation, the nurse's initial action should be to reassess the client to evaluate if restraints are still required before considering reapplication. This step ensures that the restraints are only used when absolutely necessary, promoting the client's safety and autonomy. Documentation and monitoring are essential, but reassessment of the client's condition takes precedence to provide individualized care.
