A nurse is caring for an adolescent who has hemophilia A and is scheduled for wisdom teeth extractions. Prior to the procedure, the nurse should anticipate that the client will receive which of the following products?

Fresh frozen plasma

Recombinant

Packed RBCS

Prophylactic antibiotics

Answer and Explanation

The Correct Answer is B

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.

Correct Answer is ["175"]

Explanation

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.

A. "The IV heparin increases the effects of the warfarin and decreases the length of your hospital stay. " B. "Warfarin takes several days to work, so the IV heparin will be used until the warfarin reaches a therapeutic level." C. "Both heparin and warfarin work together to dissolve the dots. " D. "I will call the provider to get a prescription for discontinuing the IV heparin today."

Correct Answer is B

Explanation

A. While heparin and warfarin both work as anticoagulants, IV heparin is not typically used to increase the effects of warfarin or decrease the length of hospital stay. Heparin is often administered initially to rapidly achieve therapeutic anticoagulation while waiting for warfarin to reach its full therapeutic effect, but it is not intended to directly enhance the action of warfarin.
B. This statement is accurate and provides a clear explanation to the client. Warfarin, an oral anticoagulant, takes several days to achieve a therapeutic level in the bloodstream and to exert its anticoagulant effect. During this time, IV heparin is continued to prevent clot formation until the therapeutic level of warfarin is reached.
C. While both heparin and warfarin work to prevent blood clots, they do not directly dissolve existing clots. Rather, they prevent the formation of new clots and the growth of existing ones. This explanation does not fully address the client's question regarding why both medications are necessary.
D. Discontinuing IV heparin prematurely without reaching a therapeutic level of warfarin could increase the risk of thrombus formation or embolization. Therefore, discontinuing IV heparin should be done under the guidance of the provider based on the client's INR levels and the target therapeutic range for warfarin.
