A nurse is to preparing to administer cefazolin 1 g by intermittent IV bolus over 30 min. Available is cefazolin 1 g in 100 ml dextrose 5% in water (DSW). The drop factor of the manual IV tubing is 10 gtt/mL. The nurse should set the manual IV infusion to deliver how many gtt/min? (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 ["33"]
- To calculate the gtt/min, use the formula: gtt/min = (volume in mL x drop factor) / time in min
- Plug in the values from the question: gtt/min = (100 mL x 10 gtt/mL) / 30 min - Simplify and solve: gtt/min = 1000 gtt / 30 min
- Divide both sides by 30: gtt/min = 33.33 gtt/min
- Round to the nearest whole number: gtt/min = 33 gtt/min
- The nurse should set the manual IV infusion to deliver 33 gtt/min

Correct Answer is ["43.2"]
Explanation
- To calculate the dose of enoxaparin, first convert the client's weight from pounds to kilograms by dividing by 2.2.
- 95 lbs / 2.2 = 43.18 kg
- Then, multiply the weight in kilograms by the prescribed dose of 1 mg/kg. - 43.18 kg x 1 mg/kg = 43.18 mg
- Finally, round the answer to the nearest tenth of a milligram.
- 43.18 mg ≈ 43.2 mg
- Therefore, the nurse should administer 43.2 mg of enoxaparin per dose subcutaneously every 12 hours.
Correct Answer is B
Explanation
A. Was hit by another soccer player on the field - This suggests a possible collision injury, which may result in various types of leg or foot injuries, but it doesn't specifically point to an ankle sprain.
B. Twisted his foot while running bases during a baseball game - This mechanism of injury is consistent with an ankle sprain. Twisting the foot during a sudden movement can cause stretching or tearing of ligaments around the ankle.
C. Has ankle pain after running a 16 km (10 mile) race - This suggests an overuse or strain injury, which could include various types of leg injuries, but it doesn't specifically point to an ankle sprain.
D. Dropped a 4.5 kg (10 lb) weight on his lower leg at a health club - This suggests a potential crush or impact injury to the lower leg, which may result in various types of leg injuries, but it doesn't specifically point to an ankle sprain.
