900 units/hr

1,000 units/hr

2.000 units/hr

1,100 units/hr

Answer and Explanation

The Correct Answer is D

Given:

Total Heparin in solution: 25,000 units

Volume of solution: 250 mL

Infusion rate: 11 mL/hr

Step 1: Calculate the concentration of Heparin in the solution:

Concentration (units/mL) = Total Heparin (units) / Volume of solution (mL)

Concentration (units/mL) = 25,000 units / 250 mL

Concentration (units/mL) = 100 units/mL

Step 2: Calculate the infusion rate in units/hr:

Infusion rate (units/hr) = Infusion rate (mL/hr) x Concentration (units/mL)

Infusion rate (units/hr) = 11 mL/hr x 100 units/mL

Infusion rate (units/hr) = 1100 units/hr

Correct Answer is A

Explanation

Given:

Volume of fluid: 3,000 mL

Infusion time: 24 hours

Formula:

Flow rate (mL/hr) = Volume (mL) / Time (hr)

Step 1: Calculate the infusion rate in mL/hr:

Flow rate (mL/hr) = 3,000 mL / 24 hr

Flow rate (mL/hr) = 125 mL/hr

A. Potassium level of 3.0 mEg/L B. BP L 132/82 mm Hg C. Digoxin level of 1.2 ng/mL D. Heart rate of 66/min

Correct Answer is A

Explanation

A) Potassium level of 3.0 mEq/L:
A potassium level of 3.0 mEq/L is below the normal range (3.5-5.0 mEq/L) and indicates hypokalemia. This is a critical finding for a patient taking digoxin. Hypokalemia increases the risk of digoxin toxicity because low potassium levels enhance the action of digoxin on the heart, potentially leading to arrhythmias. Therefore, the nurse should immediately report this finding to the provider for correction of the potassium imbalance.

B) BP of 132/82 mm Hg:
A blood pressure of 132/82 mm Hg is within the normal to slightly elevated range for adults. There is no immediate cause for concern related to the administration of digoxin, as this value is not indicative of hypotension or any immediate contraindication.

C) Digoxin level of 1.2 ng/mL:
A digoxin level of 1.2 ng/mL is within the therapeutic range (0.5-2.0 ng/mL). There is no indication that this level would need to be reported, as it is appropriate for digoxin therapy and not indicative of toxicity.

D) Heart rate of 66/min:
A heart rate of 66/min is within the normal range for an adult at rest (60-100 bpm). A heart rate below 60 bpm may warrant further assessment when taking digoxin, as it can cause bradycardia. However, a heart rate of 66 is not alarming and does not necessitate reporting to the provider, as it is still within an acceptable range for most individuals.
