Correct Answer: B

Rationale: The correct answer is B: 'Check for air leaks and ensure proper chest tube function.' This is the most important assessment for a client with a chest tube post-surgery because it ensures that the chest tube is functioning properly. Checking for air leaks helps prevent complications such as pneumothorax or hemothorax. Choice A is incorrect because clamping the chest tube periodically can lead to serious complications and should not be done unless specifically ordered by a healthcare provider. Choice C is important for promoting lung expansion but is not the most critical assessment related to the chest tube. Choice D is also important for respiratory function but is not the priority when assessing a chest tube post-surgery.

Correct Answer: B

Rationale: The correct action to verify a client's identity when administering medications is to scan the client's facility identification band. This method ensures accuracy and helps prevent medication errors. Asking the client's full name (Choice A) may not be reliable as names can be similar, leading to confusion. Calling the client's name (Choice C) may not be effective if there are multiple clients with the same name in the facility. Verifying with a second nurse (Choice D) is an important safety measure for certain tasks but is not specifically for verifying a client's identity.

Correct Answer: B

Rationale: The correct task to delegate to the LPN is administering initial NG tube feeding. LPNs are trained to carry out this task as it falls within their scope of practice. Inserting an IV catheter (Choice A) is typically performed by registered nurses. Administering insulin (Choice C) and giving medications for diabetes (Choice D) involve assessing the patient's condition and adjusting medication dosage, which are responsibilities of registered nurses or higher-level healthcare providers.

Correct Answer: D

Rationale: Dehydration management involves a comprehensive approach that includes monitoring fluid intake to assess the severity of dehydration, encouraging oral rehydration to replenish fluids orally if the patient can tolerate it, and administering IV fluids in severe cases where oral intake is insufficient. Choosing just one of these options may not address the diverse needs of patients with dehydration. Therefore, selecting 'All of the above' is the most appropriate response as it encompasses the various strategies required for effective dehydration management.

Correct Answer: C

Rationale: The correct answer is C: Potassium. Furosemide is a diuretic that can cause potassium depletion due to increased urinary excretion. Monitoring potassium levels is crucial to prevent hypokalemia, which can lead to serious complications such as cardiac arrhythmias. Sodium (choice A) levels are not typically affected by furosemide. Glucose (choice B) monitoring is important with other medications like corticosteroids but is not directly related to furosemide use. Calcium (choice D) levels are not significantly impacted by furosemide.
