A nurse in the emergency department is caring for a client who had a seizure and became unresponsive after stating they had a sudden, severe headache. The client's vital signs are as follows: blood pressure of 198/110 mm Hg, pulse of 82/min, respirations of 24/min, and a temperature of 38.2° C (100.8° F). Which of the following neurological disorders should the nurse suspect?

Choice A: Topical ointment Topical ointment forms of nitroglycerin are used for their long-acting effects. The medication is absorbed slowly through the skin, providing a steady level of drug in the bloodstream. This form is not designed for rapid relief of acute angina attacks but rather for prevention.

Choice B: Sustained-release Sustained-release forms of nitroglycerin are designed to release the medication slowly over an extended period. This route is also not suitable for treating acute symptoms because it does not provide immediate relief but is used for long-term management of angina pectoris. Nitroglycerin is a medication used primarily to treat angina pectoris (chest pain) and heart failure. It works by relaxing the smooth muscles and dilating the blood vessels, which increases blood flow to the heart and decreases its workload. The route of administration can significantly affect the onset and duration of the medication’s action.

Choice C: Sublingual The sublingual route, where the medication is placed under the tongue, allows for rapid absorption into the bloodstream through the rich supply of blood vessels found in the area. This form of nitroglycerin acts quickly, usually within 1 to 3 minutes, and is the preferred choice for immediate relief of angina pain. When rapid onset is required for relief from acute angina symptoms, the sublingual route is the most appropriate choice for administering nitroglycerin. It provides quick absorption and fast action, making it an essential treatment option for patients experiencing chest pain due to angina.

Choice D: Transdermal patch Transdermal patches release nitroglycerin slowly through the skin and into the bloodstream. Like topical ointments and sustained-release forms, they are used for long-term prophylaxis of angina and not for rapid relief.

Choice A reason: Instructing the client to perform range-of-motion exercises to his lower extremities immediately after cardiac catheterization is not recommended. The client should maintain bed rest with the affected leg straight to prevent bleeding from the catheter insertion site.

Choice B reason: Ambulating the client 1 hour following the procedure is not advised. After femoral artery access, the client is typically required to remain on bed rest with the affected leg straight for several hours to ensure hemostasis and prevent bleeding².

Choice C reason: Restricting the client's fluid intake is not a standard post-procedure action. Adequate hydration is important after cardiac catheterization to help flush the contrast dye used during the procedure from the body, unless contraindicated.

Choice D reason: Assessing the color, temperature, and pulse in the affected extremity is crucial for detecting signs of bleeding, hematoma formation, or arterial occlusion. These assessments should be performed regularly as part of post-cardiac catheterization care².
