Final answer:
C. Systolic blood pressure of 84 A systolic blood pressure of 84 mmHg is a contraindication to the administration of nitroglycerin, as it can exacerbate hypotension.
Step-by-step explanation:
The clinical finding that represents a contraindication to the administration of nitroglycerin is a systolic blood pressure of 84. Nitroglycerin is a vasodilator used to treat angina and certain types of myocardial infarctions (heart attacks), by improving blood flow and oxygen delivery to the heart muscle. However, it can lead to dangerous drops in blood pressure. Patients with a systolic blood pressure less than 90 mmHg, or who have experienced a significant drop in blood pressure, may be at risk of hypotension if given nitroglycerin. Therefore, a systolic blood pressure of 84 mmHg is considered a contraindication for nitroglycerin administration.
A contraindication to the administration of nitroglycerin is a systolic blood pressure of 84. Nitroglycerin is a vasodilator that relaxes the smooth muscle in the coronary vessels, improving blood flow. However, if the systolic blood pressure is too low, such as 84, the administration of nitroglycerin can cause a further decrease in blood pressure, leading to hypotension and potentially causing harm to the patient.
