Correct Answer: B

Rationale: The correct intervention when managing a client with delirium is to identify any reversible causes. Delirium can be caused by various factors such as infections, medications, dehydration, or metabolic imbalances. Administering antipsychotic medications (Choice A) may worsen delirium and should be avoided unless necessary for specific indications. Providing a low-stimulation environment (Choice C) is beneficial as it can help reduce agitation and confusion in individuals with delirium. Increasing environmental stimulation (Choice D) is contraindicated as it can exacerbate symptoms in delirious patients. Therefore, the priority should be on identifying and addressing reversible causes to effectively manage delirium.

Correct Answer: A

Rationale: Correct answer: Monitoring airway patency and providing humidified oxygen is crucial in managing a patient with a tracheostomy to ensure proper breathing and oxygenation. Ensuring the airway is clear and providing oxygen support are immediate priorities. Providing education on tracheostomy care (Choice B) is important for long-term management but not the immediate priority. Suctioning airway secretions and changing tracheostomy ties (Choice C) are tasks that may be necessary but do not address the primary concern of maintaining airway patency. Providing a high-protein diet and ensuring fluid restriction (Choice D) are unrelated to the immediate management of a tracheostomy.

Correct Answer: C

Rationale: Administering 4 oz of orange juice is the appropriate action for a client experiencing hypoglycemia due to diabetes mellitus. Orange juice contains simple sugars that can quickly raise blood glucose levels. Insulin (Choice A) would further lower blood sugar, worsening the condition. Glucagon (Choice B) is used in severe hypoglycemia when the client cannot take anything by mouth. Administering 1 L of water (Choice D) is not indicated in hypoglycemia treatment; the priority is to raise blood sugar levels. Therefore, the correct choice is to administer orange juice to address the low blood sugar in this situation.

Correct Answer: A

Rationale: The priority for the nurse when caring for a patient with a chest tube is to ensure tube patency and observe for air leaks. This is essential to prevent complications such as pneumothorax and ensure the patient's lung function. While maintaining sterile technique during dressing changes, monitoring drainage, recording output, and observing for signs of infection and subcutaneous emphysema are also important, ensuring tube patency takes precedence as it directly impacts the patient's respiratory status and overall safety.

Correct Answer: A

Rationale: Corrected Rationale: Regular monitoring for infection and dressing changes are essential aspects of caring for a patient with a central venous catheter. Infections are a significant risk with these catheters, so vigilant monitoring and timely dressing changes help prevent complications. Choice B is important too, but ensuring catheter patency and flushing are more focused on maintaining the functionality of the catheter rather than infection prevention. Choice C is also important for patient education, but the immediate concern for a healthcare professional is monitoring and preventing infections related to the catheter. Choice D is not directly related to the care of a central venous catheter.
