The nurse is providing education to a client who receives a prescription for zolpidem.
Which information about the medication should the nurse include?

Choice A rationale:

Verapamil is a calcium channel blocker and is expected to decrease heart rate by inhibiting calcium influx into cardiac cells, particularly in the SA (sinoatrial) node, where it can slow down the heart's electrical impulses.

Choice B rationale:

Increased contractility is not an expected outcome of verapamil use. In fact, verapamil's main action is to decrease myocardial contractility, making it useful for treating conditions like angina and atrial fibrillation.

Choice C rationale:

Verapamil is known to dilate coronary arteries, which can improve blood flow to the heart muscle and relieve symptoms of angina.

Choice D rationale:

Reduced blood pressure is an expected outcome of verapamil use due to its vasodilatory effects on peripheral blood vessels. This can be beneficial in treating hypertension and angina.

Choice E rationale:

Relieved chest pain is an expected outcome of verapamil use, particularly in the case of variant angina (Prinzmetal's angina), as it helps to relax coronary arteries and reduce coronary artery spasm, which is a common cause of chest pain in this condition.

The correct answer is choicea. Carry on with surgical preparation of the client without a signed informed consent.

Choice A rationale:

In emergency situations where immediate surgery is required to save a patient’s life and no family members are available, the doctrine of presumed consent applies.This means that healthcare providers can proceed with necessary treatment without a signed informed consent to prevent serious harm or death.

Choice B rationale:

Asking the man’s friend to sign the informed consent is not appropriate because friends are not legally authorized to provide consent for medical procedures unless they have legal documentation proving their authority.

Choice C rationale:

Notifying the unit manager for an emergency court order would delay the necessary surgery, which could be detrimental to the patient’s health. In emergencies, immediate action is required, and waiting for a court order is not feasible.

Choice D rationale:

Continuing to provide life support while searching for a guardian would also delay the necessary surgery. In life-threatening situations, immediate surgical intervention is prioritized over finding a legal guardian.
