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.
Normal ranges for serum aminotransferases are 7 to 56 U/L for alanine aminotransferase (ALT) and 10 to 40 U/L for as

Correct Answer is A
Explanation
Diaphoresis means excessive sweating, which is one of the symptoms of hypoglycemia. Hypoglycemia occurs when the blood sugar level is lower than the normal range, which can cause dizziness, confusion, weakness, hunger, and other signs.
Choice B is wrong because flushing of the face is not a symptom of hypoglycemia.
Flushing can be caused by other conditions, such as fever, allergic reactions, or rosacea.
Choice C is wrong because fruity breath is a symptom of hyperglycemia, not hypoglycemia.
Hyperglycemia means high blood sugar level, which can cause the body to produce ketones that give the breath a fruity odor.
Choice D is wrong because unpredictable behaviors are not a specific symptom of hypoglycemia.
However, hypoglycemia can cause confusion, irritability, or anxiety, which may affect the behavior of some people.
The normal range of blood sugar level for most people is between 70 and 130 mg/dL (3.9 and 7.2 mmol/L) before meals and less than 180 mg/dL (10 mmol/L) after meals.
However, this may vary depending on the individual and the type of diabetes.
It is important to monitor the blood sugar level regularly and treat hypoglycemia promptly by eating or drinking a simple sugar source.
Correct Answer is A
Explanation
Glycerin suppositories are safe and effective for infants with constipation. They work by lubricating and softening the stool, and stimulating the rectal muscles to contract.
Choice B is wrong because magnesium hydroxide is not recommended for infants under 6 months of age, and may cause diarrhea, electrolyte imbalance, or magnesium toxicity.
Choice Cis wrong because watchful waiting for 24 hours may not be enough to relieve the infant’s discomfort and may lead to further complications such as fecal impaction or dehydration.
Choice Dis wrong because feeding supplementation with free water may not be sufficient to treat constipation, and may dilute the infant’s intake of nutrients and electrolytes.
