A client who has atrial fibrillation is prescribed warfarin therapy.
Which of the following statements by the client indicates an understanding of the medication?

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.

c) Call the healthcare provider and clarify the prescription. Correct

This is the action that the PN should take if they believe that a prescription for a child is incorrect because the dosage prescribed is the usual adult dosage.

Calling the healthcare provider and clarifying the prescription is the safest and most effective way to prevent medication errors and ensure the child's safety. The PN should not administer the medication until they are sure that it is correct and appropriate for the child.

a) Tell the pharmacy to send an accurate child's dosage.

This is not the action that the PN should take if they believe that a prescription for a child is incorrect because the dosage prescribed is the usual adult dosage.

Telling the pharmacy to send an accurate child's dosage is not appropriate, as it may cause confusion, delay, or conflict with the healthcare provider's orders. The PN should not assume that they know the correct dosage for the child without consulting with the healthcare provider.

b) Ask another nurse if adult dosages are ever given to children.

This is not the action that the PN should take if they believe that a prescription for a child is incorrect because the dosage prescribed is the usual adult dosage. Asking another nurse if adult dosages are ever given to children is not helpful, as it may not provide accurate or reliable information.

The PN should not rely on another nurse's opinion or experience without verifying it with the healthcare provider.

d) Request verification of the prescription by the charge nurse.

This is not the action that the PN should take if they believe that a prescription for a child is incorrect because the dosage prescribed is the usual adult dosage. Requesting verification of the prescription by the charge nurse is not necessary, as it may waste time and resources.

The PN should be able to communicate directly with the healthcare provider and clarify any doubts or concerns about the prescription.
