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 B
Explanation
This is because mitt restraints can reduce the patient’s mobility and circulation in the hands, and range of motion exercises can help prevent contractures, stiffness, and edema.
Choice A is wrong because removing the mitts when the client is asleep can increase the risk of self-injury or removal of therapeutic equipment.
Choice C is wrong because tying the restraints securely around the wrists and to the bed can impair the patient’s circulation and cause nerve damage.
Choice D is wrong because placing the restraints loosely to allow increased freedom of movement can cause entanglement or strangulation.

.“I need to receive 3 doses of hepatitis B vaccination to assure protection.” This statement indicates that the person understands that hepatitis B is a serious infection that can be prevented by vaccination.
Hepatitis B vaccine is given as a series of 3 shots over a period of 6 months.
Choice A is wrong because hepatitis A is not usually transmitted through unprotected sex, but through ingestion of contaminated food or water or direct contact with an infected person.
Hepatitis A can also be prevented by vaccination.
Choice C is wrong because hepatitis C can be transmitted through IV drug use, as well as blood transfusions, organ transplants, needlestick injuries, and sharing personal items such as razors or toothbrushes with an infected person.
Hepatitis C can cause chronic liver disease and there is no vaccine for it.
Choice D is wrong because there is a vaccine for hepatitis A, which can provide lifelong protection against the infection.
