A client with severe nausea has a one time order for ondansetron (Zofran) 8 mg IVPB to be administered over 15 minutes. The medication is diluted in 50 mL of D5W. The tubing drop factor is 15 gtt/mL. How many drops per minute should be given?
Answer and Explanation

The Correct Answer is ["50"]

To calculate the drops per minute for the ondansetron infusion, we need to use the formula:

drops per minute = (volume in mL x drop factor) / time in minutes

In this case, the volume is 50 mL, the drop factor is 15 gtt/mL, and the time is 15 minutes. Plugging these values into the formula, we get:

drops per minute = (50 x 15) / 15

drops per minute = 750 / 15

drops per minute = 50

Therefore, the nurse should set the infusion pump to deliver 50 drops per minute of ondansetron to the client with severe nausea.

Related Questions

Correct Answer is ["A","B","C","E"]

Explanation

A. Retinal Hemorrhage

Uncontrolled hypertension can damage the blood vessels in the eyes, leading to retinal hemorrhages. This can result in vision problems and, in severe cases, vision loss.

B. Ventricular Hypertrophy

Uncontrolled hypertension causes the heart to pump against increased resistance, leading to the thickening and enlargement of the left ventricle. Ventricular hypertrophy is a response to the increased workload on the heart and is associated with an increased risk of heart failure.

C. Cerebrovascular Disease

Hypertension is a major risk factor for cerebrovascular diseases, including strokes. Elevated blood pressure can damage the blood vessels in the brain, increasing the risk of stroke. Strokes can have serious consequences, affecting various neurological functions.

D. Venous Insufficiency

Venous insufficiency is not typically directly associated with uncontrolled hypertension. It is more commonly related to problems with the venous system, such as damaged valves in the veins, leading to poor blood flow back to the heart. While hypertension can affect arteries, venous insufficiency is a distinct condition.

E. Transient Ischemic Attacks (TIAs)

Uncontrolled hypertension increases the risk of transient ischemic attacks (TIAs), which are brief episodes of neurological dysfunction caused by temporary disruption of blood flow to the brain. TIAs are often considered warning signs of an increased risk of stroke.

Correct Answer is ["125"]

Explanation

To calculate the amount of mL that the client should receive, we need to use the formula:

mL = (g * 5 mL) / mg

where g is the ordered dose of the medication, mg is the concentration of the medication, and mL is the volume of the solution.

Plugging in the given values, we get:

mL = (4 g * 5 mL) / 160 mg

Simplifying, we get:

mL = 0.125 g/mL

Multiplying by 1000 to convert grams to milligrams, we get:

mL = 125 mg/mL

Therefore, the client should receive 125 mL of the solution.
