A nurse is preparing to administer gentamicin 2 mg/kg IV to a client who weighs 220 Ib.
How many mg should the nurse administer? (Round the answer to the nearest whole number.
Use a leading zero if it applies. Do not use a trailing zero.).
200 mg.
180 mg.
400 mg.
440 mg.
The Correct Answer is A
To calculate the dose of gentamicin to administer to a client who weighs 220 Ib, first convert the client’s weight from pounds to kilograms.
220 Ib is equivalent to 100 kg (220 Ib /.2 Ib/kg = 100 kg).
Then, multiply the client’s weight in kilograms by the dose of gentamicin per kilogram: 100 kg * 2 mg/kg = 200 mg.
Therefore, the nurse should administer 200 mg of gentamicin.
Choice B is wrong because 180 mg is not the correct dose.
Choice C is wrong because 400 mg is not the correct dose.
Choice D is wrong because 440 mg is not the correct dose.

Choice A is wrong because older adults may actually have a decreased sense of pain.
Choice B is wrong because older adults may experience changes in their sleep patterns, including difficulty falling asleep or staying asleep.
Choice D is wrong because while urinary incontinence can be a common issue among older adults, it is not limited to nighttime.
Correct Answer is B
Explanation
A nurse can delegate the task of performing a simple dressing change to an assistive personnel.
Delegation is an essential nursing skill that allows a qualified healthcare worker, like an RN, to transfer routine and low-risk duties to nursing assistive personnel.
This frees up the RN’s time to address more pressing matters, including critical patients and tasks.

Choice A is wrong because changing IV tubing is not a task that can be delegated to assistive personnel.
Choice C is wrong because inserting an NG tube is not a task that can be delegated to assistive personnel.
Choice D is wrong because evaluating the healing of an incision is not a task that can be delegated to assistive personnel.
These tasks require the expertise and training of a licensed nurse.
