A nurse is preparing to administer acyclovir 10 mg/kg IV to a client who weighs 132 lbs. Available is acyclovir IV injectable solution 30 ing/ind Hone many mL 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.)
The Correct Answer is ["20"]
Step 1: Convert Weight to Kilograms
- 1 lb = 0.4536 kg
- 132 lb × 0.4536 kg/lb = 59.87 kg
Step 2: Calculate Total Dose of Acyclovir
- Prescribed dose = 10 mg/kg
- Total dose = 59.87 kg × 10 mg/kg = 598.75 mg
Step 3: Determine the Volume of Injectable Solution
- Acyclovir IV concentration = 30 mg/mL
- Volume = 598.75 mg ÷ 30 mg/mL = 19.96 mL
The nurse should administer 20 mL (rounded to the nearest whole number) of acyclovir IV injectable solution.

Correct Answer is D
Explanation
A. Dominant antecubital basilic vein:
While the basilic vein in the antecubital area is a suitable site, the nondominant arm is generally preferred when possible to minimize interference with the client's activities.
B. Nondominant dorsal venous arch:
The dorsal venous arch, located on the back of the hand or wrist, is a common site for peripheral IV catheter placement. It is preferred over other sites like the antecubital area due to lower risks of complications such as phlebitis and infiltration. Additionally, using the nondominant hand reduces interference with daily activities.
C. Dominant distal dorsal vein:
The dorsal veins are generally not the first choice for peripheral IV catheter placement due to the potential for complications such as infiltration.
D. Nondominant forearm basilic vein:
Nondominant forearm basilic vein: The basilic vein in the nondominant forearm is often a suitable site for peripheral IV catheter placement. The nondominant arm is preferred when feasible to minimize disruption of activities for the client. However, its preferred to start the IV infusion distally to provide the option of proceeding up the extremity if the vein is ruptured or infiltration occurs; if infiltration occurs from the antecubital vein, the lower veins in the same arm usually should not be used for further puncture sites.
Correct Answer is ["60"]
Explanation
1.Convert the available lidocaine concentration to mg/mL:
2 g of lidocaine = 2000 mg
2000 mg ÷ 500 mL = 4 mg/mL
2. Determine the mL/min required to deliver 4 mg/min:
4 mg/min ÷ 4 mg/mL = 1 mL/min
3. Convert mL/min to mL/hr:
1 mL/min × 60 minutes = 60 mL/hr
