Answer and Explanation

The Correct Answer is B

A. Aortic regurgitation: Balloon valvuloplasty is not effective for regurgitation disorders as it does not address the backflow problem.

B. Mitral valve stenosis: Balloon valvuloplasty is commonly used to relieve mitral valve stenosis by improving the opening of the valve, often due to rheumatic heart disease.

Correct Answer is B

Explanation

A. Oral hypoglycemic medications: These are not used in DKA; IV insulin is required after fluid resuscitation.

B. 0.9% sodium chloride IV bolus: Clients with DKA are often severely dehydrated. Administering isotonic fluids (0.9% sodium chloride) is the first priority to restore intravascular volume.

C. Glucocorticoid medications: Glucocorticoids can worsen hyperglycemia and are not indicated.

D. Dextrose 5% in 0.45% sodium chloride: This is used later, after glucose levels drop to 250 mg/dL, to prevent hypoglycemia.

A. Place the client in a side-lying position. B. Place a tongue depressor in the client's mouth. C. Remove objects from the client's bed. D. Assess the client's airway patency. E. Restrain the client.

Correct Answer is ["A","C","D"]

Explanation

A. Place the client in a side-lying position. This prevents aspiration and maintains an open airway during a seizure.

B. Place a tongue depressor in the client's mouth: This is contraindicated as it can cause injury or airway obstruction.

C. Remove objects from the client's bed. This reduces the risk of injury during seizure activity.

D. Assess the client's airway patency. Airway patency is a priority to prevent hypoxia.

E. Restrain the client: Restraining can cause injury to the client or caregiver.
