After having a pulmonary angiogram, a client is diagnosed with a pulmonary embolism (PE). Which intervention is most important for the nurse to include in the client's plan of care?

The correct answer is: C. Experiences facial swelling after eating crab.

Choice A Reason: Drinking a glass of water in the past 2 hours is not typically a concern unless the patient has been instructed to fast. For most cardiac catheterization procedures, patients are asked to fast for a certain period before the procedure to reduce the risk of aspiration. However, small sips of water may be allowed with medications.

Choice B Reason: While reports of left chest wall pain are clinically significant and warrant investigation, they are not as immediately concerning for the angioplasty procedure itself. Chest pain is a symptom that may have led to the decision to perform angioplasty but does not pose an immediate risk of complication during the procedure as an allergy might.

Choice C Reason: As previously mentioned, experiencing facial swelling after eating crab is indicative of a shellfish allergy. This is important because the contrast dye used in angioplasty may contain iodine, and patients with shellfish allergies could have an increased risk of an allergic reaction to the iodine in the dye. It is essential to explore this further to take necessary precautions, such as premedication with antihistamines or using a different contrast agent.

Choice D Reason: Verbalizing a fear of being in a confined space, or claustrophobia, is a psychological concern that should be addressed to ensure the patient’s comfort during the procedure. However, it does not pose a direct risk to the safety of the angioplasty procedure like an allergic reaction does. Managing patient anxiety is important, but it is not the most critical factor to explore prior to the procedure.

A) Incorrect- Furosemide is a loop diuretic used to treat conditions such as edema and hypertension. It does not directly relate to the client's history of gout or the risk of calcium kidney stones.
B) Incorrect- Low-dose aspirin is often used for its antiplatelet effects to prevent cardiovascular events. It does not directly relate to the client's history of gout or the risk of calcium kidney stones.
C) Correct- Allopurinol is a medication used to treat gout by reducing the production of uric acid in the body. However, allopurinol can also increase the risk of forming calcium oxalate kidney stones, which is the type of kidney stone mentioned in the client's history. Calcium oxalate stones are the most common type of kidney stone, and they are composed primarily of calcium and oxalate. In this case, the client has a history of gout and is prescribed allopurinol. The nurse should bring the client's prescription for allopurinol to the healthcare provider's attention because

it has the potential to contribute to the formation of kidney stones, which could exacerbate the client's existing condition.
D) Incorrect- Enalapril is an angiotensin-converting enzyme (ACE) inhibitor used to treat hypertension and heart failure. It does not directly relate to the client's history of gout or the risk of calcium kidney stones.
