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 D
Explanation
Choice A reason: This is incorrect because hypotension is not a common effect of long-term corticosteroid therapy. Corticosteroids can cause fluid retention and sodium retention, which can lead to hypertension, not hypotension.
Choice B reason: This is incorrect because muscle weakness is not the most impactful effect of long-term corticosteroid therapy on the patient's recovery. Corticosteroids can cause muscle wasting and loss of muscle mass, which can affect the patient's mobility and strength, but not as much as delayed wound healing.
Choice C reason: This is incorrect because osteoporosis is not the most impactful effect of long-term corticosteroid therapy on the patient's recovery. Corticosteroids can cause bone loss and increased risk of fractures, which can affect the patient's bone health and stability, but not as much as delayed wound healing.
Choice D reason: This is correct because delayed wound healing is the most impactful effect of long-term corticosteroid therapy on the patient's recovery. Corticosteroids can impair the inflammatory response and the immune system, which can slow down the healing process and increase the risk of infection. This can affect the patient's recovery time and quality.
Correct Answer is D
Explanation
Choice A reason:This is incorrect. When mixing regular (clear) and NPH (cloudy) insulin, air should be injected into the NPH vial first, then into the regular insulin vial. This prevents contamination of the regular insulin with NPH insulin.
Choice B reason: This is incorrect because the nurse should not shake the NPH insulin vial, but rather roll it gently between the palms to mix it. Shaking can cause bubbles and affect the accuracy of the dose.
Choice C reason: This is incorrect because the nurse should draw up the regular insulin into the syringe first, then the NPH insulin. This prevents mixing of the NPH insulin with the regular insulin in the vial.
Choice D reason: This is correct. Regular insulin should always be clear. If it appears cloudy, it may be contaminated or expired and should be discarded.
