While changing a postoperative patient’s dressing, the nurse notices purulent drainage at the site.
Before reporting this to the healthcare provider, which of the patient’s lab values should the nurse check?

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.

Choice A rationale

Walking at least once an hour at work can be beneficial for overall health and can contribute to maintaining energy balance. However, it may not be the most effective action for maintaining energy balance for a person who already exercises 2 to 3 times per week.

Choice B rationale

Increasing exercise intensity can help burn more calories and can contribute to maintaining energy balance. However, it’s important to note that exercise alone may not be sufficient for maintaining energy balance if not combined with a balanced diet.

Choice C rationale

Avoiding foods with high carbohydrate levels is not necessarily an effective action for maintaining energy balance. Carbohydrates are a primary source of energy for the body. While it’s important to choose complex carbohydrates over simple ones, avoiding carbohydrates altogether is not recommended.

Choice D rationale

Selecting foods that are lower in caloric density is an effective action for maintaining energy balance. Foods that are lower in caloric density, such as fruits and vegetables, can provide essential nutrients without contributing excessive calories. This can help maintain energy balance and prevent weight gain.
