Correct Answer: A

Rationale: Administering glucagon is the recommended intervention for severe hypoglycemia, especially when the patient is unconscious or unable to consume oral glucose. Glucagon helps increase blood glucose levels rapidly by stimulating the release of stored glucose from the liver. Providing a source of glucose (Choice B) can be challenging if the patient is unable to swallow or unconscious, making glucagon a more effective option. Monitoring blood sugar levels (Choice C) and assessing vital signs (Choice D) are important aspects of managing hypoglycemia but are not the immediate intervention for severe cases where prompt elevation of blood glucose levels is necessary.

Correct Answer: C

Rationale: The correct answer is C: Gastric ulcer formation. Prednisone, a corticosteroid, increases the risk of gastric ulcer formation, especially with long-term use. While prednisone can also lead to hyperglycemia (choice A) and hypertension (choice B) as adverse effects, monitoring for gastric ulcer formation is a priority due to its association with corticosteroid therapy. Diarrhea (choice D) is not a common adverse effect of prednisone and is less likely compared to gastric ulcers.

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.

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: C

Rationale: Irritability in infants can indicate worsening dehydration, which needs to be reported. Weight gain (Choice A) would be a positive finding, indicating adequate fluid intake. Poor appetite (Choice B) is common with diarrhea but not as concerning as irritability. Decreased urination (Choice D) can also be a sign of dehydration, but irritability is more specific to worsening dehydration in this case.
