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
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.

Correct Answer is D
Explanation
Choice A: Eliciting the gag reflex is a way to assess cranial nerve IX (glossopharyngeal) and X (vagus), which are responsible for the sensation and motor function of the pharynx and larynx.
Choice B: Testing visual acuity is a way to assess cranial nerve II (optic), which is responsible for the sense of vision.
Choice C: Observing for facial symmetry is a way to assess cranial nerve VII (facial), which is responsible for the motor function of the facial muscles and the sensation of taste.
Choice D: Checking the pupillary response to light is a way to assess cranial nerve III (oculomotor), which is responsible for the motor function of most of the eye muscles, including those that control pupil size and lens shape.
Correct Answer is C
Explanation
Choice A Reason: This is incorrect because hypervolemia is a condition of excess fluid volume in the body. A client who has an extensive burn injury is more likely to have hypovolemia, which is a condition of low fluid volume, due to fluid loss from the damaged skin and capillaries.
Choice B Reason: This is incorrect because metabolic alkalosis is a condition of high blood pH and high bicarbonate level. A client who has an extensive burn injury is more likely to have metabolic acidosis, which is a condition of low blood pH and low bicarbonate level, due to increased production of lactic acid and ketones from tissue hypoxia and breakdown.
Choice C Reason: This is correct because low hemoglobin is a common laboratory finding in a client who has an extensive burn injury. Hemoglobin is the protein in red blood cells that carries oxygen. A client who has an extensive burn injury may have low hemoglobin due to hemolysis, which is the destruction of red blood cells, or hemorrhage, which is the loss of blood.
Choice D Reason: This is incorrect because hyperkalemia is a condition of high blood potassium level. A client who has an extensive burn injury may have hyperkalemia in the early phase of injury, due to cell damage and potassium release, but it is usually transient and followed by hypokalemia, which is a condition of low blood potassium level, due to fluid loss and potassium depletion.
