A nurse is providing teaching to a client who has angina pectoris and a new prescription for nitroglycerin sublingual tablets. Which of the following statements by the client indicates an understanding of the teaching?
"I'll dial 911 if I still have pain after taking 4 nitroglycerin tablets over a 20-minute period."
"I'll dial 911 if 1 nitroglycerin tablet does not relieve my pain, and then take up to 2 more tablets 5 minutes apart while waiting."
“I’ll dial 911 when I have pain and then take the nitroglycerin tablets."
"I'll dial 911 if I still have pain after taking 3 nitroglycerin tablets 5 minutes apart."
None
None
The Correct Answer is B
A. Taking 4 tablets over 20 minutes exceeds the recommended limit of 3 doses in 15 minutes and can dangerously delay emergency care if the pain is due to a heart attack.
B. The correct teaching is to take 1 sublingual nitroglycerin tablet at the onset of angina and, if pain persists after 5 minutes, activate emergency services while taking up to 2 additional tablets at 5-minute intervals. This ensures rapid symptom relief while promptly initiating emergency care if the angina does not resolve.
C. Calling 911 before taking any nitroglycerin delays immediate treatment of angina. Sublingual nitroglycerin is meant to relieve pain quickly, so contacting emergency services comes after assessing response to the first dose.
D. Waiting until all 3 tablets are taken before calling 911 can dangerously delay care if the angina is progressing to myocardial infarction. Early activation after the first dose ensures patient safety and timely intervention.

Correct Answer is A
Explanation
A. "Try taking a mild analgesic to relieve the headache." is correct. Nitroglycerin-induced headaches are a common side effect due to vasodilation. Mild analgesics such as acetaminophen can help alleviate the discomfort.
B. Taking only one dose to reduce the risk of a headache is inappropriate. The client should follow the prescribed dosing regimen to manage angina effectively. Skipping doses may increase the risk of angina attacks.
C. Requesting a different medication is not necessary. Nitroglycerin is an effective treatment for stable angina, and headaches typically diminish over time as the body adjusts to the medication.
D. Stating that nothing can be done to relieve the headaches is incorrect. Headaches from nitroglycerin can be managed with mild analgesics or by adjusting the timing of medication administration.
Correct Answer is C
Explanation
A. Deep vein thrombosis is not a known risk factor for obstructive sleep apnea. Sleep apnea is primarily related to airway obstruction rather than circulatory issues.
B. Being female is incorrect. Obstructive sleep apnea is more common in males than females, although postmenopausal women have an increased risk.
C. Obesity is correct. Excess weight, particularly around the neck, increases the risk of airway obstruction during sleep, making obesity a major risk factor for obstructive sleep apnea.
D. Atherosclerosis is not a direct risk factor. However, untreated obstructive sleep apnea can contribute to cardiovascular issues, including hypertension and atherosclerosis.
