A nurse is teaching a group of nurses about the administration of nitroglycerin. Which of the following routes of administration provides the most rapid onset for the client?
Topical ointment
Sustained-release
Sublingual
Transdermal patch
The Correct Answer is C
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.

Correct Answer is A
Explanation
Aspiration is a common complication in patients with dysphagia post-stroke due to impaired swallowing reflexes, leading to food or liquid entering the lungs.
Choice B reason: Gastroesophageal reflux disease could be a concern but is not directly related to dysphagia post-stroke.
Choice C reason: Peptic ulcer disease is not typically a complication of dysphagia post-stroke.
Choice D reason: Dumping syndrome is related to rapid gastric emptying post-meal, not dysphagia post-stroke.
Correct Answer is C
Explanation
Choice A reason: Bradycardia, which is a slower than normal heart rate, is not a common finding associated with renal calculi. Renal calculi, or kidney stones, typically cause symptoms related to the urinary system rather than directly affecting the heart rate.
Choice B reason: Bradypnea, or abnormally slow breathing, is also not a typical symptom of renal calculi. Patients with kidney stones may experience changes in urination patterns, such as frequency or urgency, but not typically changes in respiratory rate.
Choice C reason: Severe pain is indeed the most common symptom associated with renal calculi. This pain, known as renal colic, is often sudden in onset, very severe, and may radiate from the back down to the lower abdomen or groin. The pain is caused by the stone moving into the ureter and causing a blockage, which leads to increased pressure and stretching of the kidney or ureter. Renal calculi can cause a range of symptoms, with severe pain being the most prominent and often the first symptom that leads individuals to seek medical care. The pain is typically very intense and can be accompanied by other symptoms such as nausea, vomiting, and hematuria (blood in the urine).
Choice D reason: Nocturia, or frequent urination at night, can be a symptom of renal calculi, especially if the stones affect the bladder or cause urinary tract infections. However, the most characteristic symptom of renal calculi is severe pain, not necessarily nocturia.
