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 C
Explanation
A. Increased mucus production blocking the alveoli is incorrect. While mucus production can be an issue in COPD, it is more characteristic of chronic bronchitis rather than emphysema.
B. Infections decreasing ventilation is incorrect. Although infections can worsen emphysema symptoms, they are not the primary cause of chronic hypoxia in these clients.
C. Lack of adequate surface area for aeration is correct. Emphysema leads to alveolar destruction and loss of elasticity, reducing the surface area available for gas exchange, which causes chronic hypoxia.
D. Inflammation of the bronchioles decreasing breathing capacity is incorrect. While airway inflammation is seen in conditions like asthma and chronic bronchitis, emphysema is primarily characterized by alveolar damage rather than airway inflammation.
Correct Answer is A
Explanation
A. Holding the breath for 10 seconds after inhaling allows the medication to be absorbed into the lungs effectively.
B. The client should wait at least 1 minute between inhalations if a second dose is needed, not 10 minutes.
C. The client should take a slow, deep breath while releasing the medication to ensure better lung deposition.
D. The client should inhale while pressing the inhaler, not exhale, to properly receive the medication.
