A client is on mechanical ventilation and the client's spouse wonders why famotidine is needed since the client "only has lung problems." What response by the nurse is best?

It will prepare the gastrointestinal tract for enteral feedings.

It will increase the motility of the gastrointestinal tract.

It will keep the gastrointestinal tract functioning normally.

It will prevent ulcers from the stress of mechanical ventilation.

Answer and Explanation

The Correct Answer is D

Choice A reason:

While preparing the gastrointestinal tract for enteral feedings is important, it is not the primary reason for administering famotidine. Famotidine is typically used to reduce gastric acid production, not to prepare the GI tract for feedings.

Choice B reason:

Increasing the motility of the gastrointestinal tract is not the primary function of famotidine. Famotidine is an H2 receptor antagonist that works by decreasing the production of stomach acid.

Choice C reason:

Keeping the gastrointestinal tract functioning normally is a broad statement and does not specifically address the reason for administering famotidine. The drug's role in preventing stress ulcers is more relevant to the patient's current condition.

Choice D reason:

Famotidine is used to prevent stress ulcers, which can occur in critically ill patients, including those on mechanical ventilation. The stress of illness and mechanical ventilation increases the risk of developing gastric ulcers, and famotidine helps reduce this risk by decreasing gastric acid secretion.

Correct Answer is D

Explanation

Choice A reason:

Mechanical ventilation is not typically required for patients with rib fractures unless there is severe respiratory compromise or other underlying issues that necessitate ventilatory support.

Choice B reason:

Preparing for a chest tube is not generally required for isolated rib fractures unless there is an associated pneumothorax or hemothorax. Chest tubes are used to manage complications that involve air or blood in the pleural space.

Choice C reason:

Needle decompression is performed in emergencies to relieve tension pneumothorax. This procedure is not indicated for simple rib fractures without evidence of a tension pneumothorax.

Choice D reason:

An intercostal nerve block for pain management is an appropriate intervention for a patient with rib fractures. It helps control pain, allowing the patient to breathe deeply and cough effectively, which is important for preventing complications such as pneumonia.

A. Level of consciousness. B. Focal neurological exam. C. Body posturing. D. Vital signs.

Correct Answer is A

Explanation

Choice A reason:

Assessing the level of consciousness is the most important nursing assessment for detecting early signs of a declining condition in a patient with a severe concussion. Changes in consciousness can indicate worsening brain injury or increased intracranial pressure, and prompt recognition is crucial for timely intervention.

Choice B reason:

A focal neurological exam is important but is more specific to identifying localized neurological deficits rather than detecting general deterioration. It is essential but secondary to monitoring the overall level of consciousness.

Choice C reason:

Body posturing can indicate severe brain injury or increased intracranial pressure, but it typically occurs later in the course of deterioration. Early changes in the level of consciousness are more sensitive indicators of a declining condition.

Choice D reason:

Vital signs are important to monitor, but changes in vital signs can occur later in the progression of a declining neurological status. Early detection of changes in the level of consciousness allows for more timely intervention.
