Why is acute pain particularly dangerous for a patient having a heart attack?
Release of prostaglandins lowers the patient’s heart rate and blood pressure.
Release of substance P narrows the airways and leads to hypoxemia.
Release of endorphins causes dangerous elevation of blood pressure.
Stimulation of the sympathetic nervous system will increase cardiac workload.
The Correct Answer is D
Choice A reason: This is an incorrect choice because release of prostaglandins lowers the patient’s heart rate and blood pressure is not a reason why acute pain is particularly dangerous for a patient having a heart attack. Prostaglandins are inflammatory mediators that are involved in pain perception and modulation, but they do not have a direct effect on the heart rate and blood pressure. In fact, some prostaglandins may have a protective role in the cardiovascular system by preventing platelet aggregation and vasodilation.
Choice B reason: This is an incorrect choice because release of substance P narrows the airways and leads to hypoxemia is not a reason why acute pain is particularly dangerous for a patient having a heart attack. Substance P is a neuropeptide that is involved in pain transmission and modulation, but it does not have a significant effect on the airways or the oxygen level. Substance P may cause bronchoconstriction in some patients with asthma or chronic obstructive pulmonary disease, but this is not a common or serious complication of acute pain.
Choice C reason: This is an incorrect choice because release of endorphins causes dangerous elevation of blood pressure is not a reason why acute pain is particularly dangerous for a patient having a heart attack. Endorphins are endogenous opioids that are involved in pain inhibition and modulation, but they do not have a major effect on the blood pressure. Endorphins may cause a slight increase in blood pressure by activating the opioid receptors in the brainstem, but this is not a significant or harmful response to acute pain.
Choice D reason: This is the correct choice because stimulation of the sympathetic nervous system will increase cardiac workload is a reason why acute pain is particularly dangerous for a patient having a heart attack. The sympathetic nervous system is part of the autonomic nervous system that is responsible for the fight-or-flight response, which is triggered by acute pain. The sympathetic nervous system will increase the heart rate, blood pressure, and cardiac contractility, which will increase the oxygen demand and consumption of the heart. This will worsen the ischemia and injury of the myocardium, and may lead to arrhythmias, heart failure, or cardiac arrest.

Correct Answer is B
Explanation
Choice A reason: This is an incorrect choice because the nurse braids the patient’s long hair to prevent tangles is not an action that demonstrates the concept of nurse autonomy. Nurse autonomy refers to the ability and right of nurses to make independent decisions about patient care without interference from others. Braiding the patient’s hair is a personal care task that does not require the nurse to use their own judgment or expertise.
Choice B reason: This is the correct choice because the nurse checks the policy manual before changing the central line dressing is an action that demonstrates the concept of nurse autonomy. Nurse autonomy refers to the ability and right of nurses to make independent decisions about patient care without interference from others. Checking the policy manual before changing the central line dressing shows that the nurse is responsible for following the evidence-based guidelines and standards of practice for this procedure.
Choice C reason: This is an incorrect choice because the nurse counts the patient’s pulse before administering digoxin is not an action that demonstrates the concept of nurse autonomy. Nurse autonomy refers to the ability and right of nurses to make independent decisions about patient care without interference from others. Counting the patient’s pulse before administering digoxin is a routine task that is prescribed by the physician and does not involve the nurse’s own decision making.
Choice D reason: This is an incorrect choice because the nurse directs the nursing assistant to obtain the patient's weight is not an action that demonstrates the concept of nurse autonomy. Nurse autonomy refers to the ability and right of nurses to make independent decisions about patient care without interference from others. Directing the nursing assistant to obtain the patient's weight is a task that is delegated by the nurse and does not reflect the nurse’s own authority or initiative.
