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?

A.

"I'll dial 911 if I still have pain after taking 4 nitroglycerin tablets over a 20-minute period."

B.

"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."

C.

“I’ll dial 911 when I have pain and then take the nitroglycerin tablets."

D.

"I'll dial 911 if I still have pain after taking 3 nitroglycerin tablets 5 minutes apart."

Answer and Explanation

The Correct Answer is D

A. Taking 4 nitroglycerin tablets is incorrect. The maximum dose is 3 tablets, taken 5 minutes apart. If chest pain persists after the third dose, the client should seek emergency help.  
B. Calling 911 after only one dose is incorrect. The correct protocol is to take up to three doses before seeking emergency assistance unless symptoms worsen rapidly.  
C. Calling 911 immediately before taking nitroglycerin is incorrect. The client should attempt to relieve the chest pain with nitroglycerin before calling for emergency help.  
D. Calling 911 if pain persists after taking 3 nitroglycerin tablets 5 minutes apart is correct. Persistent chest pain despite nitroglycerin use suggests a possible myocardial infarction (MI), requiring immediate medical intervention.

Explanation

  • Obtain intravenous (IV) access: IV access is necessary for administering medications, fluids, and emergency interventions.
  • Obtain the client's family history: While family history is important for long-term cardiac risk assessment, it is not a priority in the acute phase of chest pain management.
  • Apply continuous ECG monitoring: Continuous ECG monitoring is critical for detecting arrhythmias, ischemic changes, and potential myocardial infarction (MI).
  • Administer O₂ to maintain oxygen saturation greater than 90%: Oxygen therapy is indicated in clients with suspected MI if their oxygen saturation is below 90% to prevent further myocardial ischemia.
