A client with hepatitis C has been experiencing symptoms of gastroesophageal reflux.
What H antagonist would be most appropriate for this client’s needs?
Nizatidine.
Ranitidine.
Cimetidine.
Famotidine.
The Correct Answer is D
Famotidine is a histamine type 2 receptor antagonist (H blocker) which is commonly used for treatment of acid-peptic disease and heartburn. Famotidine has been linked to rare instances of clinically apparent acute liver injury, but it is less likely to cause hepatotoxicity than cimetidine, another H blocker. Famotidine also has fewer drug interactions than cimetidine.
Choice A is wrong because nizatidine is another H blocker that can cause mild and transient serum aminotransferase elevations.
Nizatidine has not been linked to cases of clinically apparent liver injury, but it has not been widely used.
Choice B is wrong because ranitidine is another H blocker that can cause mild and transient serum aminotransferase elevations.
Ranitidine has also been associated with rare instances of clinically apparent liver injury, some of which were fatal or required liver transplantation.
Choice C is wrong because cimetidine is another H blocker that can cause mild and transient serum aminotransferase elevations.
Cimetidine has also been implicated in several cases of clinically apparent acute liver injury, some of which were severe and led to acute liver failure and death.
Cimetidine also has many drug interactions due to its inhibition of cytochrome P enzymes.

Correct Answer is C
Explanation
This strategy can help the client read the numbers on the syringe and prepare the correct dose of insulin. A magnifying glass is also an affordable and accessible tool for the client.
Choice A is wrong because preparing a week’s supply of syringes and refrigerating them can affect the potency and sterility of insulin.
It can also increase the risk of errors or confusion.
Choice B is wrong because asking a neighbor to come over every day to prepare the medication can compromise the client’s privacy and independence.
It can also be unreliable and inconvenient for both parties.
Choice D is wrong because changing the client to oral antidiabetics is not possible for type 1 diabetes.
People with type 1 diabetes need to take insulin for life because their pancreas cannot make insulin.
Oral antidiabetics are only effective for people with type 2 diabetes who have functioning pancreatic beta cells
