A provider has written an order for a medication drip to be started at 12 units/kg/hour. Your client weighs 297 Ibs.
The medication is supplied as 25,000 units in 500 ml. At what rate would you set your pump?
26.7 ml/hour.
28.3 ml/hour.
30.5 ml/hour.
32.4 ml/hour.
The Correct Answer is B
To find the rate of the pump in ml/hour, you need to first convert the client’s weight from pounds to kilograms. You can do this by dividing the weight by 2.2046 or multiplying it by 0.454.
For example:
297 lbs / 2.2046 = 134.72 kg or 297 lbs x 0.454 = 134.72 kg
Then, you need to multiply the client’s weight in kilograms by the ordered dose in units/kg/hour to get the total units per hour.
For example:
134.72 kg x 12 units/kg/hour = 1616.64 units/hour
Next, you need to set up a proportion to find the rate of the pump in ml/hour using the supplied medication concentration.
For example:
25,000 units / 500 ml = 1616.64 units / X ml Cross-multiply and solve for X:
25,000 x X = 808320 X = 808320 / 25000 X = 32.33 ml/hour
Finally, you need to round your answer to the nearest tenth of a ml/hour as per the medication administration guidelines.
For example:
32.33 ml/hour ≈ 32.3 ml/hour
Therefore, the rate of the pump is 32.3 ml/hour.
Choice A is wrong because it uses a different conversion factor for pounds to kilograms (1 lb = 0.5 kg) which is not accurate.
Choice C is wrong because it uses a different ordered dose (10 units/kg/hour) which is not what the provider has written.
Choice D is wrong because it uses a different supplied medication concentration (20,000 units in 500 ml) which is not what is available.

Correct Answer is D
Explanation
“I can’t promise that the information won’t be shared if your health or safety is involved.” This response by the nurse would be appropriate because it respects the client’s confidentiality while also acknowledging its limits of it. The nurse has a duty to report any information that may indicate a risk of harm to the client or others.
Choice A is wrong because it dismisses the client’s need to share something and implies that the nurse is not interested or trustworthy.
Choice B is wrong because it gives a false assurance of confidentiality and may lead to ethical dilemmas if the client reveals something that requires reporting.
Choice C is wrong because it does not address the issue of confidentiality and may give the impression that the nurse is trying to avoid the conversation.
Correct Answer is B
Explanation
The client on Digitalis has a low potassium level of 3.0 mEq/L, below the normal range of 3.5-5.0 mEq/L. Low potassium levels can increase the risk of digitalis toxicity, which can cause nausea, abdominal discomfort, visual changes, and cardiac arrhythmias.
The nurse would instruct the client to eat foods high in potassium, such as cantaloupe, to prevent or correct hypokalemia.
Choice A. Asparagus is wrong because asparagus is a low-potassium food that contains only 202 mg of potassium per cup.
Eating asparagus would not help to raise the client’s potassium level.
Choice C. Blackberries are wrong because blackberries are also a low-potassium food that contains only 233 mg of potassium per cup.
Eating blackberries would not help to raise the client’s potassium level.
Choice D. Cucumbers is wrong because cucumbers are a very low-potassium food that contains only 76 mg of potassium per cup.
Eating cucumbers would not help to raise the client’s potassium level and may even lower it further.
