A nurse is reviewing the medication list for a client who has a new diagnosis of type 2 diabetes mellitus. The nurse should recognize which of the following medications can cause glucose intolerance?
Dextromethorphan
Prednisone
Atorvastatin
Cimetidine
The Correct Answer is B
Choice A reason: Dextromethorphan is a cough suppressant that does not affect blood glucose levels. It is safe to use for clients with diabetes.
Choice B reason: Prednisone is a corticosteroid that can cause glucose intolerance by increasing glucose production and decreasing insulin sensitivity. It can worsen hyperglycemia and increase the risk of diabetic complications.
Choice C reason: Atorvastatin is a statin that lowers cholesterol levels and reduces the risk of cardiovascular disease. It does not cause glucose intolerance and may have a beneficial effect on glycemic control.
Choice D reason: Cimetidine is a histamine-2 receptor antagonist that reduces stomach acid production and treats ulcers and gastroesophageal reflux disease. It does not cause glucose intolerance and has no significant interaction with diabetes medications.

Correct Answer is B
Explanation
Choice A reason: Benzonatate is not the correct answer. Benzonatate is a cough suppressant that works by numbing the throat and lungs. It does not help in the removal of mucus.
Choice B reason: Guaifenesin is the correct answer. Guaifenesin is an expectorant that works by thinning and loosening the mucus in the airways. It helps in the removal of mucus by making it easier to cough up.
Choice C reason: Diphenhydramine is not the correct answer. Diphenhydramine is an antihistamine that works by blocking the effects of histamine, a chemical that causes allergy symptoms. It does not help in the removal of mucus.
Choice D reason: Dextromethorphan is not the correct answer. Dextromethorphan is a cough suppressant that works by affecting the signals in the brain that trigger the cough reflex. It does not help in the removal of mucus.
Correct Answer is C
Explanation
Choice A reason: Increased intestinal peristalsis is not an effect of adrenergic agonist drugs, but rather of cholinergic drugs, which stimulate the parasympathetic nervous system. Adrenergic agonist drugs activate the sympathetic nervous system, which decreases intestinal motility.
Choice B reason: Bronchial constriction is also not an effect of adrenergic agonist drugs, but rather of cholinergic drugs, which cause bronchoconstriction and increased secretions. Adrenergic agonist drugs cause bronchodilation and decreased secretions.
Choice C reason: Increased heart rate is an effect of adrenergic agonist drugs, which stimulate the beta-1 receptors in the heart, causing increased cardiac output and blood pressure. This is why adrenergic agonist drugs are used to treat conditions such as shock, cardiac arrest, and heart failure.
Choice D reason: Constricted pupils is not an effect of adrenergic agonist drugs, but rather of cholinergic drugs, which cause miosis or pupil constriction. Adrenergic agonist drugs cause mydriasis or pupil dilation.
