nurse is caring for a client who is newly-admitted and has angina. The client asks the nurse, "Why am I taking nitroglycerin?" Which of the lowing responses should the nurse make?
"Nitroglycerin dilates cardiac blood vessels to deliver more oxygen to the heart."
"Nitroglycerin relieves nausea and prevents vomiting, which could lead to aspiration."
"Nitroglycerin acts as a bronchodilator to open small airways and decrease shortness of breath."
"Nitroglycerin decreases chest pain by dissolving blood clots that are occluding the arteries."
The Correct Answer is A
A. "Nitroglycerin dilates cardiac blood vessels to deliver more oxygen to the heart." Nitroglycerin works by dilating the coronary arteries, increasing blood flow and oxygen delivery to the heart muscle, thereby reducing angina.
B. "Nitroglycerin relieves nausea and prevents vomiting, which could lead to aspiration." Nitroglycerin does not have an antiemetic function or impact nausea and vomiting.
C. "Nitroglycerin acts as a bronchodilator to open small airways and decrease shortness of breath." Nitroglycerin is not a bronchodilator. It does not act on the airways but instead works on blood vessels.
D. "Nitroglycerin decreases chest pain by dissolving blood clots that are occluding the arteries." Nitroglycerin does not dissolve blood clots. Thrombolytic agents are used for clot dissolution, not nitroglycerin.

Correct Answer is A
Explanation
A. Troponin T: Troponin T remains elevated for 10 to 14 days after a myocardial infarction. This protein is highly specific for cardiac muscle injury and is used to confirm myocardial infarction.
B. Creatinine phosphokinase: Creatinine phosphokinase (CPK) typically returns to normal levels within 3 days after a myocardial infarction, so it would no longer be elevated at this point.
C. Myoglobin: Myoglobin rises early after a myocardial infarction but is not specific to heart muscle and returns to normal within 24 hours, so it would not be elevated at this time.
D. Creatinine kinase-MB: Creatinine kinase-MB (CK-MB) usually returns to normal levels within 2 to 3 days after a myocardial infarction, so it is unlikely to still be elevated 6 days later.
Correct Answer is B
Explanation
A. Use the diaphragm of the stethoscope to listen to the carotid pulsations. The apical pulse is located at the apex of the heart, not at the carotid artery. This option does not describe the correct location or use of the stethoscope.
B. Count the apical pulsations for a full minute. Counting for a full minute is the correct method for assessing an apical pulse, particularly in clients on cardiovascular medications, to ensure accurate detection of any irregularities.
C. Check the apical pulse with a Doppler device. A Doppler device is typically used to assess peripheral pulses, not the apical pulse. A stethoscope is the appropriate tool for apical pulse assessment.
D. Press the stethoscope firmly against the client's skin. While the stethoscope should be placed firmly enough to hear heart sounds, excessive pressure can distort the sounds and is not necessary.
