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 A
Explanation
Choice A reason: Taking the bronchodilator inhaler first will help to open up the airways and make it easier for the corticosteroid inhaler to reach the lungs and reduce inflammation. This will improve the effectiveness and safety of the inhalers.
Choice B reason: Taking the corticosteroid inhaler first may not be as effective as taking the bronchodilator inhaler first, because the airways may be constricted and prevent the corticosteroid from reaching the lungs. This may reduce the anti-inflammatory effect of the corticosteroid and increase the risk of side effects.
Choice C reason: Taking these two drugs at least 2 hours apart is not necessary and may not be practical for the patient. The bronchodilator and the corticosteroid can be taken together, as long as the bronchodilator is taken first.
Choice D reason: It does matter which inhaler the patient uses first, because the order of the inhalers can affect their efficacy and safety. The patient should always use the bronchodilator inhaler first, followed by the corticosteroid inhaler.
Correct Answer is C
Explanation
Choice A reason: Rotating the injection sites within the same location for a week is not correct. The client should rotate the injection sites within the same location each day to prevent lipodystrophy and ensure consistent absorption.
Choice B reason: Storing the unopened vials of insulin in the freezer is not correct. The client should store the unopened vials of insulin in the refrigerator, not the freezer, to prevent damage to the insulin.
Choice C reason: Drawing up the regular insulin before the NPH insulin is correct. The client should draw up the clear (regular) insulin before the cloudy (NPH) insulin to prevent contamination of the regular insulin with the NPH insulin.
Choice D reason: Injecting the insulin into the muscle for faster absorption is not correct. The client should inject the insulin into the subcutaneous tissue, not the muscle, to ensure appropriate absorption and prevent hypoglycemia.
