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
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.

Explanation
Here's how we can find the desired flow rate:
- Total volume to infuse (in minutes):
- We need to convert the infusion time from hours to minutes.
- Time (minutes) = Time (hours) x 60 minutes/hour
- Time (minutes) = 2 hours x 60 minutes/hour
- Time (minutes) = 120 minutes
- Total volume to infuse (in mL):
- Given volume = 250 mL
- Drop factor (gtts/mL):
- Given drop factor = 15 gtts/mL
- Flow rate (gtts/minute):
- Flow rate = Total volume (mL) / Time (minutes) x Drop factor (gtts/mL)
- Flow rate = 250 mL / 120 minutes x 15 gtts/mL
To simplify the calculation, we can divide all values by 5 (as long as we perform the division on both sides of the equation, the answer won't change):
- Flow rate = (250 mL / 5) / (120 minutes / 5) x (15 gtts/mL / 5)
- Flow rate = 50 mL / 24 minutes x 3 gtts/mL
- Flow rate = 2.0833... gtts/minute (round to nearest whole number)
- Rounded flow rate (gtts/minute):
- Flow rate = 2 gtts/minute
Therefore, the nurse should adjust the flow rate to deliver approximately 2 gtts/minute.
Correct Answer is ["0.5"]
Explanation
Let's convert the digoxin dosage from mcg (micrograms) to mg (milligrams) and then divide it by the amount of digoxin per tablet to find out how many tablets are needed.
Steps to solve:
- Convert digoxin dose from mcg to mg:
- We know 1 mg is equal to 1000 mcg.
- Digoxin dose (mg) = Digoxin dose (mcg) / 1000 mcg/mg
- Digoxin dose (mg) = 125 mcg / 1000 mcg/mg
- Digoxin dose (mg) = 0.125 mg
- Calculate the number of tablets required:
- Number of tablets = Digoxin dose (mg) / Digoxin per tablet (mg)
- Number of tablets = 0.125 mg / 0.25 mg/tablet
Since the result is 0.5, we need to round to the nearest tenth.
Answer: The nurse should administer 0.5 tablets per dose.
