A client with heart failure receives intravenous nitroglycerin that is being titrated, and the nurse frequently monitors the client's blood pressure. At 1200, the nurse decided to decrease the rate of nitroglycerin Based on the blood pressure history in the electronic health record, click to identify the time the nurse should have decreased the rate.

Nitroglycerin is a potent vasodilator used to reduce preload and afterload, but it can cause hypotension if the blood pressure drops too low. The nurse must continuously monitor blood pressure and adjust the infusion rate to maintain adequate organ perfusion while achieving therapeutic effects. The decision to decrease the infusion is based on recognizing the point at which blood pressure falls below safe parameters. Rationale: • 1100: At 1100, the blood pressure is 116/60 mm Hg, which shows a significant drop from previous readings while still maintaining borderline perfusion pressure. This is the earliest point where the downward trend becomes clinically relevant before further decline to 102/54 at 1130. Since nitroglycerin is titrated to avoid hypotension, the nurse should proactively reduce the rate at the first sign of meaningful blood pressure decline. Early intervention prevents progression to symptomatic hypotension and end-organ hypoperfusion. • 1130 (102/54): This blood pressure is hypotensive and would indicate that the nurse should already have decreased the nitroglycerin infusion earlier. At this point, the client is at risk for inadequate organ perfusion. This confirms that intervention should have occurred at 1100, before further decline.
