When preparing a patient for a cardiac catheterization and coronary angiogram, which piece of information about the patient is crucial for the nurse to relay to the healthcare provider prior to the procedure?
The patient has been fasting for the day.
The patient has a shellfish allergy.
The patient experienced a heart attack one year ago.
The patient’s pedal pulses are rated at +1.
The Correct Answer is B
Choice A rationale
While fasting may be required before certain procedures, it is not the most crucial piece of information that the nurse needs to relay to the healthcare provider prior to a cardiac catheterization and coronary angiogram.
Choice B rationale
A shellfish allergy is crucial information because the dye used in an angiogram can cause an allergic reaction in people who are allergic to shellfish.
Choice C rationale
Although a previous heart attack is significant medical history, it is not the most crucial piece of information to relay prior to this procedure.
Choice D rationale
The rating of the patient’s pedal pulses is not the most crucial piece of information to relay prior to this procedure.

Correct Answer is C
Explanation
Choice A rationale
This sequence is incorrect because it suggests that blood goes from the lungs to the pulmonary artery, which is not accurate. The pulmonary artery carries deoxygenated blood from the heart to the lungs.
Choice B rationale
This sequence is incorrect because it suggests that blood goes from the pulmonary vein to the lungs, which is not accurate. The pulmonary vein carries oxygenated blood from the lungs to the heart.
Choice C rationale
This sequence correctly describes the direction of blood flow through the heart and lungs. Deoxygenated blood enters the right atrium, goes to the right ventricle, then is sent to the lungs via the pulmonary artery. After picking up oxygen in the lungs, the blood returns to the heart via the pulmonary vein, entering the left atrium, then the left ventricle, from where it is pumped out to the rest of the body.
Choice D rationale
This sequence is incorrect because it suggests that blood goes from the pulmonary vein to the pulmonary artery, which is not accurate. The pulmonary vein carries oxygenated blood from the lungs to the heart, and the pulmonary artery carries deoxygenated blood from the heart to the lungs.
Correct Answer is B
Explanation
Choice A rationale
While reducing anxiety and relieving pain are important aspects of care, they are not the primary goal for a client with an elevated ST segment on the ECG and an elevated cardiac troponin level. These findings indicate myocardial injury, which requires interventions to improve myocardial oxygenation and reduce cardiac workload.
Choice B rationale
The primary goal for a client with an elevated ST segment on the ECG and an elevated cardiac troponin level is to improve myocardial oxygenation and reduce cardiac workload. This can be achieved through medications, oxygen therapy, and bed rest.
Choice C rationale
Eliminating family stressors and providing a calm environment can contribute to reducing anxiety and promoting relaxation, but it is not the primary goal in this situation.
Choice D rationale
Starting the client on a low-sodium diet and decreasing fluid intake are interventions for managing heart failure, not for an acute myocardial injury.
