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
This is because assault is the threat of harm or unwanted contact, and battery is the actual physical contact without consent.
If the nurse administers the injection despite the client’s refusal, the nurse is violating the client’s autonomy and right to refuse treatment, and is committing both assault and battery.
Choice A is wrong because malice means having a deliberate intention to harm someone. The nurse may not have malice but may be acting out of ignorance or negligence.
Choice B is wrong because malpractice means a failure to meet a standard of care or conduct that causes injury or damage to a patient.
The nurse may be guilty of malpractice, but this is not the best term to describe the nurse’s action.
Choice C is wrong because negligence means a lack of care or skill that results in harm or injury.
The nurse may be negligent, but this is not the best term to describe the nurse’s action.
Correct Answer is C
Explanation
The client received a dose of clopidogrel at 2200. Clopidogrel is an antiplatelet drug that increases the risk of bleeding during and after a liver biopsy. The healthcare provider should be informed of this medication and decide whether to postpone the biopsy or administer reversal agents.
Choice A is wrong because being NPO since 2300 is a standard preparation for a liver biopsy.
Choice B is wrong because pain in the left lower quadrant and constipation are not related to the liver biopsy and do not pose an immediate risk.
Choice D is wrong because having an allergy is not relevant to the liver biopsy unless it is an allergy to the local anesthetic or contrast agent used.
