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.)
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.

Correct Answer is B
Explanation
A. Increase in serum sodium: Desmopressin, a synthetic form of vasopressin, works to decrease urine output and increase water reabsorption in the kidneys. Therefore, a therapeutic response to desmopressin would not result in an increase in serum sodium; rather, it would aim to normalize serum sodium levels by reducing excessive urine output.
B. Decrease in urine output: The primary therapeutic goal of desmopressin in the treatment of diabetes insipidus is to decrease urine output by increasing water reabsorption in the kidneys. Therefore, a decrease in urine output would indicate a positive response to the medication.
C. Increase in heart rate: Desmopressin primarily affects kidney function by increasing water reabsorption and does not typically have a direct effect on heart rate. Therefore, an increase in heart rate would not be a manifestation of a therapeutic response to desmopressin.
D. Decrease in blood pressure: Desmopressin works to increase water reabsorption in the kidneys and does not typically cause significant changes in blood pressure. Therefore, a decrease in blood pressure would not be a manifestation of a therapeutic response to desmopressin.
Correct Answer is C
Explanation
A. Monitoring heart rate is important, but it is not the priority after midazolam administration.
B. Oxygen saturation is essential, but respiratory depression typically follows changes in consciousness.
C. Level of consciousness is the priority assessment because midazolam is a benzodiazepine that causes sedation, and monitoring for excessive sedation or delayed awakening is crucial.
D. Temperature monitoring is not an immediate priority following moderate sedation.
