A client reports pain in the right heel and is requesting medication. The nurse assesses the client and administers an analgesic. The client experiences no pain relief and states that the heel pain is worse. What is an appropriate intervention by the nurse?

Call the physician to report the finding. Explanation: The best response would be to notify the physician. The nurse cannot repeat the dose of analgesic without an order. Massaging the ankle and applying moist heat would be inappropriate for a number of reasons. The client could be developing a deep vein thrombosis, which may dislodge an embolus. Unrelieved pain indicates that an adverse event is developing, and the physician should be made aware of the situation.

The provider has prescribed adenosine 6 mg IV once for the client with supraventricular tachycardia (SVT). How should the nurse administer this medication?

IV push as fast as possible Explanation: Adenosine is a high-risk medication used to treat supraventricular tachycardia. It has an extremely short half-life of only a few seconds, so this medication must be given as quickly as possible followed by a rapid flush to be effective. If it is given more slowly (over 1 to 2 minutes, 5 minutes, or more when added to a 50-ml bag of saline), the medication will not work, as it has already lost its effectiveness.

A nurse knows that the major clinical use of dobutamine is to

increase cardiac output. Explanation: Dobutamine increases cardiac output for clients with acute heart failure and those undergoing cardiopulmonary bypass surgery. Physicians may use epinephrine hydrochloride, another catecholamine agent, to treat sinus bradycardia. Physicians use many of the catecholamine agents, including epinephrine, isoproterenol, and norepinephrine, to treat acute hypotension. They don't use catecholamine agents to treat hypertension because catecholamine agents may raise blood pressure.
