A nurse is assessing a client who is receiving dopamine IV to treat left ventricular failure. Which of the following findings should indicate to the nurse that the medication is having a therapeutic eﬀect?

Systolic blood pressure is increased

Radial heart rate is increased

Cardiac output is reduced

Urine output is reduced

Answer and Explanation

The Correct Answer is A

Choice A Reason: This is correct because dopamine is a vasopressor that increases the contractility and stroke volume of the heart, which results in an increased systolic blood pressure.

Choice B Reason: This is incorrect because dopamine can cause tachycardia as a side eﬀect, but this does not indicate a therapeutic eﬀect. An increased radial heart rate can also indicate other conditions, such as anxiety, fever, or dehydration.

Choice C Reason: This is incorrect because dopamine does not reduce cardiac output, but rather increases it by improving the pumping function of the heart.

Choice D Reason: This is incorrect because dopamine does not reduce urine output, but rather increases it by stimulating the renal blood vessels and enhancing renal perfusion.

Explanation

To find the concentration of heparin in the solution, divide the amount of heparin by the volume of D5W: 25,000 units / 500 mL = 50 units/mL
To find the infusion rate, divide the prescribed dose by the concentration: 1,200 units/hr / 50 units/mL = 24 mL/hr
Round the answer to the nearest tenth/whole number: 24 mL/hr

A. Packed RBCs B. Cryoprecipitates C. Albumin D. Platelets

Correct Answer is A

Explanation

Choice A Reason: Packed RBCs are indicated for clients who have hypovolemic shock due to blood loss, as they increase the oxygen-carrying capacity of the blood and restore the blood volume.

Choice B Reason: Cryoprecipitates are indicated for clients who have hemophilia or von Willebrand disease, as they contain clotting factors that help stop bleeding.

Choice C Reason: Albumin is indicated for clients who have hypovolemic shock due to ﬂuid loss, such as from burns or ascites, as it increases the plasma oncotic pressure and draws ﬂuid into the vascular space.

Choice D Reason: Platelets are indicated for clients who have thrombocytopenia or platelet dysfunction, as they help prevent or control bleeding.
