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 A
Explanation
Cataracts are a condition where the lens of the eye becomes opaque, causing impaired vision. Blurred or cloudy vision is a common symptom of cataracts.
Some possible explanations for the other choices are:
Choice B. Burning sensation in the eye. This is not a typical symptom of cataracts, but it could indicate an infection, allergy, or dry eye syndrome.
Choice C. Inability to produce tears. This is also not a typical symptom of cataracts, but it could indicate a problem with the lacrimal glands or ducts that produce and drain tears.
Choice D. A swollen lacrimal gland. This is not a symptom of cataracts, but it could indicate an inflammation or infection of the lacrimal gland, which is located near the upper eyelid.
Normal ranges for visual acuity are 20/20 for normal vision and 20/40 for mild impairment. Visual acuity can be measured using a Snellen chart or other methods.
Correct Answer is B
Explanation
The nurse should prioritize the physical safety and stability of the patient who has been raped and stabbed.
Assessing vital signs is the first step in determining the patient’s condition and identifying any life-threatening injuries that need immediate intervention.
Choice A is wrong because calling the Sexual Nurse Examiner is not the first action to take.
The Sexual Nurse Examiner is a specially trained nurse who can perform a forensic examination and collect evidence from the patient, but this should be done after ensuring the patient’s physical safety and obtaining consent.
Choice C is wrong because calling her parents to ask for permission to treat her is not necessary or appropriate.
The patient is an adult who can consent to her own treatment unless she is incapacitated or mentally incompetent.
Calling her parents without her permission may violate her privacy and autonomy.
Choice D is wrong because contacting Security in case the perpetrator arrives is not the most urgent action to take.
The nurse should focus on the patient’s needs and not assume that the perpetrator will follow her to the hospital.
Security measures can be taken later if needed.
