Rationale: In a client with dysphagia and gastrointestinal symptoms such as hypoactive bowel sounds and a firm, distended abdomen, continuous tube feeding might exacerbate the symptoms. This can lead to complications and should be questioned by the nurse.

Correct Answer: C

Rationale: Insulin glargine is classified as a long-acting insulin. It is designed to provide a consistent level of insulin over approximately 24 hours, helping to keep blood glucose levels stable throughout the day. This long duration of action makes it suitable for basal insulin replacement in patients with type 1 diabetes, providing a background level of insulin to mimic the body's natural release of insulin between meals and overnight.

Correct Answer: C

Rationale: In children, ringing in the ears (tinnitus) can be a sign of aspirin toxicity. Aspirin toxicity can be particularly concerning in children and can lead to serious complications. Therefore, it is crucial for the nurse to prioritize monitoring for signs of aspirin toxicity, such as tinnitus, and promptly notify the healthcare provider if such symptoms occur.

Rationale: Gingival hyperplasia, or overgrowth of the gums, is a common side effect of phenytoin. Patients should maintain good oral hygiene to minimize this effect.

Correct Answer: C

Rationale: Digoxin, when prescribed to a patient with heart failure, primarily acts by strengthening cardiac contractions. This leads to an improvement in cardiac output, making it an essential medication in managing heart failure. By enhancing the force of contractions, digoxin helps the heart pump more effectively and efficiently, leading to better circulation and symptom control in patients with compromised cardiac function.
