NurseDive Free Nursing Practice Question
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.).
A. 200 mg.
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.
B. 180 mg.
Choice B is wrong because 180 mg is not the correct dose.
C. 400 mg.
Choice C is wrong because 400 mg is not the correct dose.
D. 440 mg.
Choice D is wrong because 440 mg is not the correct dose.

Therefore, the nurse should administer 200 mg of gentamicin.
Choice B is wrong because 180 mg is not the correct dose.

A nurse is caring for a client following a bilateral mastectomy. The client is often tearful and avoids looking at her dressings. Which of the following actions should the nurse take first?
A. Refer the client to a breast cancer support group.
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.
B. Identify the impact of the mastectomy on the client's body image.
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.
C. Encourage the client to assist with her dressing changes.
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.
D. Provide the client with a mirror to look at her mastectomy incisions.
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.

Choice C is wrong because injecting air into the vial with the eye of the needle immersed in the fluid can contaminate the medication.
D. Hold the syringe at a 45° angle to verify dosage.

When caring for a client who has wrist restraints after an episode of violent behavior, which of the following actions should the nurse take?
A. Tie the restraints to the side rail.
Choice A is wrong because tying the restraints to the side rail can be dangerous as it can cause injury to the client if they move suddenly.
B. Remove the restraints every 3 hr.
Choice B is wrong because removing the restraints every 3 hours is not a specific guideline and may vary depending on the facility’s policy and the client’s condition.
C. Remove one restraint at a time.
When caring for a client who has wrist restraints after an episode of violent behavior, the nurse should remove one restraint at a time. This allows the nurse to assess the client’s behavior and response to having one arm free while still maintaining some level of control and safety.
D. Secure restraints with a square knot.
Choice D is wrong because securing restraints with a square knot can make it difficult to quickly release the restraints in an emergency.
