Correct Answer is B
Explanation
Choice A rationale
Glucagon (GlucaGen) is not used for hyperglycemia. Hyperglycemia requires insulin or oral hypoglycemic agents to lower blood glucose levels.
Choice B rationale
Glucagon (GlucaGen) is used to treat hypoglycemia, especially in emergency situations when a person is unconscious or unable to consume oral glucose. It raises blood glucose levels by stimulating the liver to release stored glucose into the bloodstream.
Choice C rationale
Glucagon (GlucaGen) is not used for the treatment of type 2 diabetes mellitus. Management of type 2 diabetes typically includes lifestyle changes, oral hypoglycemic agents, and sometimes insulin therapy.
Choice D rationale
Glucagon (GlucaGen) is not used for diabetes insipidus. Diabetes insipidus is treated with medications such as desmopressin, which helps reduce urine output. .
Correct Answer is A
Explanation
Choice A rationale
Losartan is an angiotensin II receptor blocker (ARB) that helps lower blood pressure by relaxing blood vessels. It is often prescribed for clients who cannot tolerate angiotensin-converting enzyme (ACE) inhibitors like Captopril or Lisinopril due to side effects such as a persistent cough.
Choice B rationale
Digoxin is a medication primarily used to treat heart failure and atrial fibrillation. It is not typically prescribed for the management of hypertension as it does not directly lower blood pressure.
Choice C rationale
Captopril is an ACE inhibitor that can cause a persistent cough in some patients. Since the client has experienced this side effect, it is unlikely that Captopril would be prescribed again.
Choice D rationale
Lisinopril is another ACE inhibitor, similar to Captopril. Given the client's history of a cough caused by ACE inhibitors, Lisinopril is also not a suitable option.
