A nurse is preparing to administer moxifloxacin 400 mg by intermittent IV bolus over 60 min. Available is moxifloxacin 400 mg in 250 mL dextrose 5% (DSW). The drop factor of the manual IV tubing is 15 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 ["63"]
- To calculate the gtt/min, use the formula: gtt/min = (volume in mL x drop factor in gtt/mL) / time in min
- Substitute the given values: gtt/min = (250 mL x 15 gtt/mL) / 60 min - Simplify and round: gtt/min = 62.5 gtt/min ≈ 63 gtt/min
- The nurse should set the manual IV infusion to deliver 63 gtt/min

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.
Correct Answer is B
Explanation
A. Drying time is typically shorter with a synthetic cast compared to a plaster cast. Synthetic casts are designed to set faster, reducing the time the patient needs to remain immobilized during casting.
B. A synthetic cast is generally lighter in weight than a plaster cast. This can be more comfortable for the patient and may reduce the risk of muscle atrophy or discomfort associated with the cast's weight.
C. A plaster cast does not necessarily require expensive equipment for application, and both plaster and synthetic casts can be applied using relatively simple and cost-effective methods.
D. The effectiveness of immobilization is not significantly different between plaster and synthetic casts. Both types of casts can provide adequate immobilization for bone fractures, and the choice between them may depend on factors like patient preference, the type of fracture, and other clinical considerations.
