A nurse is preparing to administer enoxaparin 0.75 mg/kg subcutaneously to a client who weighs 154 lb. The amount available is enoxaparin 60 mg/0.6 mL. How many mL should the nurse administer?(Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.).

Choice A rationale:
10 mL/hr would be the correct infusion rate if the client was receiving the entire 10 mEq of potassium chloride in a 100 mL solution over 1 hour. However, the question asks for the rate at which to administer 10 mEq over 1 hour, which means the total volume should be 100 mL/hr.
Choice B rationale:
50 mL/hr would be the correct infusion rate if the client was receiving the entire 10 mEq of potassium chloride in a 100 mL solution over 2 hours. However, the question specifies 1 hour, so the rate should be higher.
Choice C rationale:
This is the correct answer. To administer 10 mEq of potassium chloride in 100 mL over 1 hour, the infusion pump should be set to deliver 100 mL/hr.
Choice D rationale:
500 mL/hr would be the correct infusion rate if the client was receiving the entire 10 mEq of potassium chloride in a 100 mL solution over 10 minutes (1/6th of an hour). However, the question specifies 1 hour, so the rate should be much lower.

Answer: A

Rationale:

A) Place the client in a room with negative airflow: Disseminated herpes zoster (shingles) requires airborne precautions because the virus can become aerosolized. A room with negative airflow helps prevent the spread of the virus to other areas, protecting healthcare workers and other patients from infection.

B) Remove isolation gown after leaving the client's room: Isolation gowns should be removed before leaving the client's room to prevent the spread of contaminants to other areas. This intervention is important for infection control but is not specific to the requirement for negative airflow in cases of disseminated herpes zoster.

C) Apply ketoconazole to the lesions three times per day: Ketoconazole is an antifungal medication and is not used for treating herpes zoster, which is caused by a viral infection. Antiviral medications, such as acyclovir, are appropriate for treating herpes zoster lesions.

D) Provide the client with eye protection for ultraviolet B light therapy: Eye protection is necessary during UVB light therapy to protect the eyes, but UVB light therapy is not a standard treatment for disseminated herpes zoster. The priority intervention is to prevent the spread of the infection by using a negative airflow room.
