A nurse is caring for a client who has a prescription for diltiazem. The nurse measures the client's vital signs and notes that the client's apical heart rate is 49/min. The nurse should prepare to administer which of the following medications?

A. The ST segment is elevated above the isoelectric line: This is correct. ST-segment elevation is a key ECG finding in acute myocardial infarction. It indicates that a portion of the heart muscle is not receiving enough blood (ischemia), which can lead to tissue damage or death (infarction).

B. The PR intervals are 0.15 second: While the PR interval is an important part of the ECG, a PR interval of 0.15 second is within the normal range and does not indicate an acute myocardial infarction.

C. The QT interval is equal to the R to R interval: The QT interval represents the time from the start of the Q wave to the end of the T wave, encompassing ventricular depolarization and repolarization. While prolonged or shortened QT intervals can be associated with certain cardiac conditions, they are not specific indicators of an acute myocardial infarction.

D. The QRS intervals are 0.08 second: The QRS interval represents ventricular depolarization1. A QRS interval of 0.08 second is within the normal range and does not indicate an acute myocardial infarction.

A. "Opioid narcotics are restricted for the client because of the risk for addiction":
This statement is not accurate and may contribute to unnecessary fear or misunderstanding about opioid use. While there is a risk of opioid addiction, it is generally low when opioids are used appropriately for pain management, especially in end-of-life care settings where the focus is on comfort and symptom management.

B. "Using opioid narcotics will limit options available for future management of pain":
This statement is misleading and may cause unnecessary concern. In end-of-life care, the priority is to provide effective pain relief and maximize comfort for the client. Opioid narcotics are an essential component of pain management in palliative and hospice care and do not necessarily limit future pain management options.

C. "The use of opioid narcotics is restricted to when death is imminent":
This statement is not accurate. Opioid narcotics can be used for pain management at various stages of illness, including but not limited to end-of-life care. While opioids are commonly used in palliative and hospice care settings, they may also be indicated for pain management in other clinical contexts.

D. "The dosage of the opioid narcotic is unlimited":
This statement is the most appropriate response. In end-of-life care, the goal of pain management is to relieve suffering and maximize comfort. Opioid dosages are titrated based on the client's pain intensity and response, and there is no strict limit to the dosage if needed to achieve adequate pain control. The priority is to ensure that the client is comfortable and free from pain as much as possible, even if higher doses of opioids are required.
