A 74-year-old woman complains of heaviness in her chest, nausea, and sweating that suddenly began about an hour ago. She is conscious and alert, but anxious. Her blood pressure is 144/84 mm Hg and her heart rate is 110 beats/min. She took two of her prescribed nitroglycerin (0.4-mg tablets) before your arrival but still feels heaviness in her chest. You should:
A. Recall that geriatric patients often have slower absorption and elimination times, which may necessitate modification of the dosing of certain drugs
B. Give her high-flow oxygen, avoid giving her any more nitroglycerin because it may cause a drop in her blood pressure, and transport
C. Transport her at once and wait at least 20 minutes before you consider assisting her with a third dose of her prescribed nitroglycerin
D. Assist her in taking one more of her nitroglycerin tablets, reassess her blood pressure, and contact medical control for further instructions
A. Recall that geriatric patients often have slower absorption and elimination times, which may necessitate modification of the dosing of certain drugs
