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

Answer and Explanation

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 B

Explanation

A. Obtaining an ECG is important but not the first priority. The immediate goal is to reduce the heart's oxygen demand.
B. Having the client sit down immediately is correct. Stopping activity reduces cardiac workload and oxygen demand, preventing further ischemia or infarction.
C. Assessing vital signs is important but should be done after stopping activity. While vital signs provide critical information, immediate intervention is needed first.
D. Administering sublingual nitroglycerin is appropriate but should be done after ensuring the client is seated. This prevents hypotension and syncope from occurring while standing.

A. The client holds his breath for 10 seconds after inhaling the medication. B. The client waits 10 min between inhalations. C. The client takes a quick inhalation while releasing the medication from the inhaler. D. The client exhales as the medication is released from the inhaler.

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.
