A patient with a tracheostomy has difficulty removing excessive, thick mucus from the respiratory tract. The nurse expects that which drug will be ordered to aid in the removal of mucus?
Benzonatate
Guaifenesin
Diphenhydramine
Dextromethorphan
The Correct Answer is B
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.
Correct Answer is B
Explanation
Choice A reason: This is incorrect because the client should avoid live vaccines while taking prednisone, as it can suppress the immune system and increase the risk of infection.
Choice B reason: This is correct because prednisone can cause hypokalemia (low potassium levels) and bananas are a good source of potassium. The client should monitor their potassium levels and eat foods rich in potassium while taking prednisone.
Choice C reason: This is incorrect because the client should avoid nonsteroidal anti-inflammatory drugs (NSAIDs) such as aspirin while taking prednisone, as they can increase the risk of gastrointestinal bleeding and ulceration.
Choice D reason: This is incorrect because a sore throat is not a common side effect of prednisone. However, the client should report any signs of infection, such as fever, sore throat, or cough, to the provider, as prednisone can mask the symptoms of infection.
