The healthcare provider prescribes cefazolin 800 mg intramuscularly every 6 hours. The available vial is labeled, "Cefazolin 1 gram," and the instructions for reconstitution state, "For IM use, add 2.5 mL sterile water for injection to provide a total volume of 3.0 mL." How many mL should the nurse administer? (Enter numerical value only. If rounding is required, round to the nearest tenth.)

Answer and Explanation

The Correct Answer is ["2.4"]

Step 1: Determine concentration
1,000 mg in 3.0 mL
Concentration = 1,000 ÷ 3 = 333.3 mg/mL

Step 2: Use the formula
Volume (mL) = Desired dose ÷ Concentration

Step 3: Insert values
Volume = 800 ÷ 333.3

Step 4: Calculate
Volume ≈ 2.4 mL

Step 5: Round to nearest tenth
2.4 → 2.4 mL

Correct Answer is ["120"]

Explanation

Step 1: Convert weight to kilograms
Weight (kg) = 176 ÷ 2.2 ≈ 80 kg

Step 2: Use the formula
Infusion rate (mL/hr) = 1.5 mL/kg/hr × weight (kg)

Step 3: Insert values
Infusion rate = 1.5 × 80

Step 4: Calculate
Infusion rate = 120 mL/hr

A. Suggest that the UAP roll both of the gloves off and inside out at the same time. B. Instruct the UAP to use two pairs of gloves when fecal contamination is likely. C. Advise the UAP that the technique being used will result in hand contamination. D. Remind the UAP to discard the gloves in the biohazard container after removal.

Correct Answer is C

Explanation

A. Rolling both gloves off at the same time is not recommended, as it increases the risk of contamination. Proper glove removal involves peeling off one glove at a time, turning it inside out to avoid contact with contaminated surfaces.

B. Using two pairs of gloves (double-gloving) may be necessary for certain high-risk procedures, but it is not required for routine bedpan handling. The focus should be on proper technique rather than adding extra gloves unnecessarily.

C. Advising the UAP that the technique being used will result in hand contamination is correct. Sliding fingers inside the contaminated glove and rolling it off inappropriately can transfer pathogens to the skin. The nurse should correct the technique by teaching the proper method: grasp the outside of one glove at the wrist, peel it off inside out, then tuck it into the remaining glove and peel off the second glove inside out. This minimizes the risk of self-contamination and infection transmission.

D. Discarding gloves in the appropriate container is important, but the primary concern here is the incorrect removal technique, which poses an immediate contamination risk. Teaching correct removal takes priority over simply reminding where to discard gloves.
