The nurse caring for a patient with a productive cough would anticipate an order for the following medication:

dextromethorphan (Robitussin)

fluticasone (Flonase)

pseudoephedrine (Sudafed)

guaifenesin (Mucinex)

Answer and Explanation

The Correct Answer is D

Choice A reason: Dextromethorphan (Robitussin) is not the correct medication for a patient with a productive cough. Dextromethorphan is a cough suppressant that works by acting on the brain to reduce the cough reflex. Dextromethorphan is used for a dry, nonproductive cough that is caused by irritation or inflammation. Dextromethorphan is not effective for a productive cough that produces mucus, and it may even be harmful by preventing the clearance of secretions from the lungs.

Choice B reason: Fluticasone (Flonase) is not the correct medication for a patient with a productive cough. Fluticasone is a corticosteroid that works by reducing inflammation and swelling in the nasal passages. Fluticasone is used for allergic rhinitis, which is a condition that causes sneezing, itching, and runny nose due to an allergic reaction. Fluticasone is not effective for a productive cough that produces mucus, and it may even worsen it by suppressing the immune system and increasing the risk of infection.

Choice C reason: Pseudoephedrine (Sudafed) is not the correct medication for a patient with a productive cough. Pseudoephedrine is a decongestant that works by constricting the blood vessels in the nasal passages and sinuses. Pseudoephedrine is used for nasal congestion, which is a condition that causes stuffy nose and difficulty breathing due to swelling of the mucous membranes. Pseudoephedrine is not effective for a productive cough that produces mucus, and it may even cause side effects such as increased blood pressure, insomnia, and anxiety.

Choice D reason: Guaifenesin (Mucinex) is the correct medication for a patient with a productive cough. Guaifenesin is an expectorant that works by thinning and loosening the mucus in the chest and throat. Guaifenesin is used for a productive cough that produces mucus, as it helps the cough to be more effective and clear the airways. Guaifenesin is generally safe and well tolerated, but it may cause some minor side effects such as nausea, vomiting, and headache.

Correct Answer is D

Explanation

Choice A reason: This is incorrect. Taking antacids does not protect the stomach from the irritation caused by spicy foods. Antacids only reduce the acidity of the stomach contents, but they do not heal the ulcer or prevent further damage.

Choice B reason: This is incorrect. Taking antacids does not affect the digestion of carbohydrates or any other nutrients. Antacids only act on stomach acid, not on the enzymes that break down food.

Choice C reason: This is incorrect. Taking antacids does not stop the stomach from producing acid. Antacids only react with the acid that is already present in the stomach, but they do not inhibit the secretion of acid by the stomach cells.

Choice D reason: This is correct. Taking antacids will help neutralize the acid that is already in the stomach, which can relieve the pain and discomfort caused by the ulcer. Antacids can also form a protective coating over the ulcer, which can help it heal faster.

A. Review the patient’s previous blood glucose levels B. No review is necessary before administering insulin C. Review the Regular insulin sliding scale for administration in the patient’s electronic medical record D. Review the patient’s previous insulin administration doses

Correct Answer is C

Explanation

Choice A reason: This is incorrect. Reviewing the patient’s previous blood glucose levels may not be helpful in determining the correct dose of insulin, as the blood glucose level can fluctuate depending on various factors, such as food intake, activity, stress, and illness. The previous blood glucose levels may not reflect the current insulin needs of the patient¹.

Choice B reason: This is incorrect. No review is not an option before administering insulin, as insulin is a highalert medication that can cause serious harm if given incorrectly. The nurse should always check the patient’s blood glucose level, the insulin order, the insulin type, the insulin dose, the insulin expiration date, and the insulin injection site before giving insulin.

Choice C reason: This is correct. Reviewing the Regular insulin sliding scale for administration in the patient’s electronic medical record is the best action to determine the correct dose of insulin. A sliding scale is a chart of insulin dosages based on blood glucose level and mealtime. It is used to adjust the insulin dose according to the patient’s blood glucose level and insulin sensitivity. The nurse should follow the sliding scale protocol and verify the insulin dose with another nurse before administering it.

Choice D reason: This is incorrect. Reviewing the patient’s previous insulin administration doses may not be helpful in determining the correct dose of insulin, as the insulin dose may vary depending on the patient’s blood glucose level and insulin sensitivity. The previous insulin doses may not reflect the current insulin needs of the patient¹.
