Which patient statement indicates that the nurse’s teaching about sublingual nitroglycerin (Nitrostat) has been effective?

Choice A rationale
Serum hemoglobin of 14.7 g/dL is within the normal range for adults, which is typically 12.0 to
16.0 g/dL for women and 13.5 to 17.5 g/dL for men. Hemoglobin is a protein in red blood cells that carries oxygen throughout the body. While it’s important to monitor hemoglobin levels, a value of 14.7 g/dL does not raise immediate concerns related to hypertension.
Choice B rationale
A blood glucose level of 96 mg/dL is considered normal. The normal range for fasting blood glucose is between 70 and 100 mg/dL1. Blood glucose levels are important to monitor, especially in patients with diabetes, but a value of 96 mg/dL is not immediately concerning in the context of hypertension.
Choice C rationale
A serum potassium level of 4.5 mEq/L is within the normal range, which is typically 3.6 to 5.2 mEq/L1. Potassium is an essential electrolyte that helps regulate heart and muscle contractions and maintain fluid balance in the body. While it’s important to monitor potassium levels, a value of 4.5 mEq/L does not raise immediate concerns related to hypertension.
Choice D rationale
A serum creatinine level of 2.8 mg/dL is high. Creatinine is a waste product that’s produced by your muscles and filtered out of your blood by your kidneys. High levels of creatinine can indicate that the kidneys aren’t working properly, which can be a complication of hypertension. Therefore, this result is the most important to communicate to the healthcare provider.

Choice A rationale
Sinus tachycardia at a rate of 110 beats/min is a normal response to exercise. During a stress test, the heart rate will naturally increase as the body’s demand for oxygen increases. A heart rate of 110 beats/min is within the expected range during moderate exercise.
Choice B rationale
An increase in blood pressure from 134/68 to 150/80 mm Hg is a normal response to exercise. During a stress test, blood pressure will naturally rise as the heart works harder to pump blood to the muscles. This increase is within the expected range during moderate exercise.
Choice C rationale
Feeling tired during a stress test on a treadmill is a normal response to exercise. Fatigue can occur as the body’s energy stores are used up during physical activity. However, if the patient reports extreme fatigue or other symptoms such as chest pain or shortness of breath, it may indicate a problem.
Choice D rationale
Inversion of T waves on the electrocardiogram during a stress test is a sign of myocardial ischemia, a condition in which the heart muscle is not getting enough oxygen. This could indicate the presence of significant coronary artery disease and is a finding that would necessitate immediate action.
