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.

Correct Answer is B
Explanation
The nurse should first identify the impact of the mastectomy on the client’s body image.
This is because the client’s behavior of avoiding looking at her dressings and being tearful suggests that she may be struggling with changes to her body image after the surgery.
By identifying and addressing this issue, the nurse can provide appropriate emotional support and interventions to help the client cope with these changes.

Choice A is not the first action the nurse should take because referring the client to a breast cancer support group may be helpful, but it is not addressing the immediate concern of the client’s emotional state.
Choice C is not the first action because encouraging the client to assist with her dressing changes may be premature if she is still struggling emotionally with her body image.
Choice D is not the first action because providing the client with a mirror to look at her mastectomy incisions may be overwhelming for her if she is not yet ready to confront her changed appearance.
Correct Answer is C
Explanation
The Weber test is a screening test for hearing performed with a tuning fork that can detect unilateral conductive hearing loss and unilateral sensorineural hearing loss.
To perform Weber’s test, strike the fork against your knee or elbow, then place the base of the fork in the midline, high on the patient’s forehead.

Choice A is wrong because delivering a series of high-pitched sounds at random intervals is not part of Weber’s test.
Choice B is wrong because holding an activated tuning fork against the client’s mastoid process is part of Rinne’s test, not Weber’s test.
Choice D is wrong because whispering a series of words softly into one ear is not part of Weber’s test.
