Patient Data

The client was given oxygen, sublingual nitroglycerin, and aspirin. After one dose of nitroglycerin, the client's pain decreased to a reported 2 on a 0 to 10 scale with squeezing pain. The client was admitted for observation and percutaneous coronary intervention (PCI) to be completed later within the evening. The client asks the nurse to explain why a PCI is being completed.

If healthcare providers (HCPs) see a narrowed heart vessel while performing a percutaneous coronary intervention (PCI), they may perform a balloon angioplasty to compress the plaque against the vessel wall and hold it there with a stent, which will lessen    and  

A. Taking tetracycline with a dairy product is not recommended because calcium binds to the medication, forming an insoluble complex that significantly reduces absorption and effectiveness. This can make the antibiotic less effective in treating acne.

B. Taking tetracycline on an empty stomach (usually 1 hour before or 2 hours after meals) is the best practice because it maximizes absorption. An empty stomach ensures that food, calcium, magnesium, or other minerals do not interfere with the drug’s bioavailability.

C. Taking tetracycline with a meal is sometimes done to reduce gastrointestinal upset, but it can decrease absorption and therapeutic effectiveness. If gastrointestinal discomfort occurs, spacing the dose around lighter foods is preferable, but the priority is maintaining absorption.

D. Taking tetracycline before an iron product is partially correct, as iron also binds tetracycline and reduces absorption. However, the broader and safest instruction is to take the medication on an empty stomach, ensuring it is not taken with iron, calcium, or other minerals. Timing around meals and supplements should be carefully managed.

A. Including an outcome that the client’s hemoglobin A1C will be less than 7% in 6 months is correct because hemoglobin A1C reflects long-term glycemic control over 2 to 3 months and is strongly correlated with the prevention of diabetes complications, including blurred vision from diabetic retinopathy. This is a measurable, realistic, and clinically meaningful outcome that directly addresses the client’s current concern.

B. Ensuring that the client self-administers medications as directed is important for overall diabetes management, but it is a process-oriented intervention rather than a clinical outcome. While adherence supports glycemic control, it does not directly measure improvement in blood glucose or risk reduction for complications like blurred vision.

C. Keeping a detailed food diary is a helpful self-management strategy, but it is a behavioral activity, not a specific measurable clinical outcome. It supports education and awareness of dietary patterns but does not directly demonstrate improved glycemic control or resolution of blurred vision.

D. Aiming for a random fasting glucose less than 140 mg/dL is partially correct, but fasting or random glucose measurements fluctuate daily and reflect short-term control. Unlike hemoglobin A1C, this measurement does not provide a comprehensive view of long-term glycemic management and is less useful as a primary outcome for preventing chronic complications.
