An S3 heart sound is auscultated in a client in her third trimester of pregnancy. What intervention should the nurse take?

A) Incorrect- The left lateral position might not provide enough lung expansion for a client in respiratory distress.
B) Incorrect- Reverse Trendelenburg (head of bed elevated, foot of bed lowered) might not provide enough lung expansion and could exacerbate respiratory distress.
C) Correct- The High-Fowler's position, where the client is sitting upright at a 90-degree angle or as upright as tolerated, helps to improve lung expansion, reduce pressure on the diaphragm, and promote optimal oxygenation. This position is commonly used for clients with respiratory distress.
D) Incorrect- The supine position may worsen pulmonary congestion and compromise lung expansion in clients with pulmonary edema.

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.
