A nurse is caring for a 1-month-old infant who weighs 3500 g and is prescribed a dose of cephazolin 50 mg/kg by intermittent IV bolus three times daily. How many mg should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero)
The Correct Answer is ["175"]
We are asked to calculate the dosage of cephazolin for a 1-month-old infant based on their weight.
Steps to solve: 1. Identify the given values:
- Dose per kg = 50 mg/kg
- Weight of the infant = 3500 g
2. Set up the formula: Dosage (mg) = Dose per kg (mg/kg) × Weight (kg)
3. Since the weight is given in grams, convert it to kilograms: 3500 g / 1000 g/kg = 3.5 kg
4. Substitute the known values into the formula and calculate: Dosage (mg) = 50 mg/kg × 3.5 kg Dosage (mg) = 175 mg
5. Round the answer to the nearest tenth: Dosage (mg) = 175.0 mg
The nurse should administer 175.0 mg of cephazolin per dose.

Correct Answer is C
Explanation
A. Stop the enema and document that the client did not tolerate the procedure:
This option may be appropriate if the client's discomfort is severe or if there are signs of distress. However, abdominal cramps are a common sensation during the administration of an enema, especially if the bowel is distended or constipated. Therefore, stopping the procedure may not be necessary at this point.
B. Encourage the client to bear down:
Bearing down might help the client expel the enema solution and relieve some discomfort. However, if the client is already experiencing abdominal cramps, bearing down could exacerbate the discomfort and is not likely to provide immediate relief.
C. Lower the height of the solution container:
This is the correct action to take. Lowering the height of the solution container reduces the flow rate of the enema solution, which can help alleviate abdominal cramps by slowing the rate of distension of the bowel. Slowing the infusion rate allows the client's colon to accommodate to the enema more comfortably.
D. Allow the client to expel some fluid before continuing:
Allowing the client to expel some fluid before continuing may provide some relief, but it does not directly address the cause of the discomfort. Lowering the height of the solution container is a more appropriate action to address the discomfort caused by abdominal cramps during the administration of the enema.
Correct Answer is B
Explanation
A. Fresh frozen plasma: Fresh frozen plasma contains clotting factors, including factor VIII, but it is not the primary treatment for hemophilia A. While it can be used in emergency situations to temporarily increase clotting factor levels, it is not typically administered prophylactically before dental procedures.
B. Recombinant factor VIII: This is the correct answer. Recombinant factor VIII is the treatment of choice for individuals with hemophilia A. It is administered to replace the deficient factor VIII in the blood, thereby promoting clot formation and preventing excessive bleeding during surgical procedures such as wisdom teeth extractions.
C. Packed red blood cells (RBCs): Packed red blood cells are not typically indicated for the treatment of hemophilia A. While they may be necessary if significant blood loss occurs during the procedure, the primary treatment is replacement of the deficient clotting factor.
D. Prophylactic antibiotics: Prophylactic antibiotics may be prescribed to prevent infection following dental procedures, especially in individuals with bleeding disorders who are at increased risk of infection due to compromised immune function. However, the primary treatment for hemophilia A prior to dental procedures is replacement therapy with clotting factor concentrates like recombinant factor VIII.
