A nurse is administering medications to a client who weighs 132 lb. The prescription reads chloramphenicol, 50mg/kg/day in 4 divided doses. Available is chloramphenicol 100 mg/mL. How many mL should the nurse give with each dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["7.5"]

Convert the client's weight from pounds to kilograms. We can use the formula 1 kg = 2.2 lb. So, 132 lb / 2.2 = 60 kg.

Calculate the total daily dose of chloramphenicol for the client. We can use the formula Dose (mg) = Weight (kg) x Dosage (mg/kg). So, 60 kg x 50 mg/kg = 3000 mg.

Divide the total daily dose by 4 to get the dose for each administration. So, 3000 mg / 4 = 750 mg.

Calculate the volume of chloramphenicol solution needed for each dose. We can use the formula Volume (mL) = Dose (mg) / Concentration (mg/mL). So, 750 mg / 100 mg/mL =

7.5 mL.

Round the answer to the nearest tenth. So, the nurse should give 7.5 mL of chloramphenicol solution with each dose.

A. “Use a nasal decongestant 15 minutes before the medication if you have a stuffy nose." B. "Plan to self-administer this medication for the next 6 months." C. "Lie down for 1 hour after administering the medication." D. "Administer the medication into one nostril once per week."

Correct Answer is D

Explanation

A. “Use a nasal decongestant 15 minutes before the medication if you have a stuffy nose": This statement is not necessary for the administration of nasal cyanocobalamin. Nasal decongestants are not routinely recommended before administering nasal medications.
B. "Plan to self-administer this medication for the next 6 months": While the duration of treatment for pernicious anemia may vary, specifying a timeframe of 6 months for self- administration is not appropriate without considering individualized treatment plans.

C. "Lie down for 1 hour after administering the medication": There is no need for the client to lie down after administering nasal cyanocobalamin. This instruction is not necessary and may not be practical.
D. "Administer the medication into one nostril once per week": This is the correct instruction for administering nasal cyanocobalamin. It is typically given once weekly into one nostril. This
method provides a convenient and effective route for vitamin B12 supplementation in clients with pernicious anemia.
