A patient arrives at the emergency department experiencing chest pain after taking sildenafil.
Based on the patient’s history, which medication should the nurse withhold?

Nitroglycerin.

Aspirin.

Morphine.

Heparin.

Answer and Explanation

The Correct Answer is A

Choice A rationale

Nitroglycerin is a medication that is commonly used to treat chest pain or angina. However, it is contraindicated in patients who have taken sildenafil (Viagra) within the last 24 hours due to the risk of severe hypotension, or low blood pressure. Sildenafil is a type of medication known as a phosphodiesterase-5 (PDE5) inhibitor, which works by relaxing the muscles in the walls of blood vessels. Nitroglycerin also works by relaxing blood vessels, so the combination of these two medications can cause a dangerous drop in blood pressure.

Choice B rationale

Aspirin is not typically withheld in patients experiencing chest pain. It is often given to patients who are suspected of having a heart attack because it works by preventing blood clots from forming and blocking the blood vessels of the heart.

Choice C rationale

Morphine is often administered to patients experiencing severe chest pain to help relieve the pain and reduce the workload of the heart. It is not typically withheld unless the patient has a known allergy or other contraindication.

Choice D rationale

Heparin is a blood thinner that is often administered to patients who are suspected of having a heart attack to prevent further blood clots from forming. It is not typically withheld unless the patient has a known allergy, other contraindication, or is at high risk of bleeding.

Correct Answer is B

Explanation

Choice A rationale

Roast pork is a protein source and does not contribute to fiber content. However, fresh strawberries are high in fiber and may not be suitable for a low-fiber diet.

Choice B rationale

Roasted turkey is a good source of protein and does not contribute to fiber content. Canned vegetables are typically lower in fiber than their fresh or frozen counterparts because the canning process tends to degrade some of the fiber. Therefore, this food selection indicates that the patient understands the prescribed low-fiber diet.

Choice C rationale

Both baked potatoes with skin and raw carrots are high in fiber. The skin of the potato and raw carrots contain insoluble fiber, which may not be suitable for a patient with ulcerative colitis on a low-fiber diet.

Choice D rationale

Pancakes made from refined flour can be part of a low-fiber diet. However, whole-grain cereals are high in fiber and may not be suitable for a patient with ulcerative colitis on a low-fiber diet.

A. “I never use the inhaler unless I am really short of breath.”. B. “I have a hard time inhaling and holding my breath after I squeeze the inhaler, but I do my best.”. C. “After I squeeze the inhaler and swallow, I always feel a slight wave of nausea, but it goes away.”. D. “I always shake the inhaler several times before I start.”.

Correct Answer is C

Explanation

Choice A rationale

Using the inhaler only when the patient is really short of breath is not an incorrect use of the inhaler. However, it might indicate that the patient is not managing their COPD effectively, as rescue inhalers like albuterol are meant to be used for quick relief of acute symptoms.

Choice B rationale

Having a hard time inhaling and holding the breath after squeezing the inhaler might suggest that the patient is not using the inhaler correctly. However, the patient’s statement that they “do their best” suggests that they are aware of the correct technique and are trying to follow it.

Choice C rationale

Swallowing after squeezing the inhaler is a clear indication of incorrect use. The medication from the inhaler is meant to be inhaled into the lungs, not swallowed. Swallowing the medication would lead to less of it reaching the lungs, reducing its effectiveness. The wave of nausea the patient experiences could be a side effect of swallowing the medication.

Choice D rationale

Shaking the inhaler several times before starting is actually part of the correct technique for using many types of inhalers.
