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 A
Explanation
A. Palpating the femoral pulse is an essential part of assessing the neurovascular status of a client with a femur fracture. The presence and strength of the femoral pulse can indicate adequate blood flow to the lower extremity.
B. While measuring the circumference of the thigh can provide some information about swelling or changes in the size of the limb, it does not directly assess neurovascular status.
C. Monitoring the client's calf for edema is important for assessing for signs of deep vein thrombosis (DVT) or venous insufficiency, but it is not the primary technique for assessing neurovascular status.
D. Instructing the client to wiggle his toes is a way to assess motor function and nerve function, which is part of the neurovascular assessment. However, it is not the initial step in assessing neurovascular status in a client with an unrepaired femur fracture. The femoral pulse should be assessed first to ensure adequate blood flow.
Correct Answer is A
Explanation
A. Holding the wrist at a 90-degree flexion is known as Phalen's maneuver, which is a test for carpal tunnel syndrome. This position puts pressure on the median nerve, potentially reproducing the client's symptoms.
B. Flexing the right arm at the elbow is not a specific test for carpal tunnel syndrome.
C. Holding the right arm straight is not a specific test for carpal tunnel syndrome.
D. Extending the right arm upward is not a specific test for carpal tunnel syndrome.
