The Correct Answer is ["1600"]
Step 1: Use the formula
Heparin dose = Dose per kg × Weight
Heparin dose = 20 units/kg × 80 kg = 1600 units

Correct Answer is C
Explanation
A. Liver involvement (hepatomegaly) can occur in infectious mononucleosis, but bed rest does not prevent liver complications; monitoring liver function is more relevant.
B. Joint involvement is not a typical complication of infectious mononucleosis, so this is not a rationale for bed rest.
C. Splenomegaly is common in infectious mononucleosis, and the enlarged spleen is at risk for rupture, especially with physical activity or trauma. Bed rest is recommended to minimize risk of splenic injury, which can be life-threatening.
D. Neck stiffness (cervical lymphadenopathy) may cause discomfort, but bed rest is not primarily to prevent neck irritation; this is a secondary consideration.
Correct Answer is D
Explanation
A. Witnessing consent is important but does not address the immediate risk of maternal hypovolemia from active bleeding.
B. Inserting a urinary catheter is useful for monitoring output but is not the first priority in a client with ongoing hemorrhage.
C. Preparing the abdominal and perineal areas may be necessary for potential cesarean birth but does not immediately stabilize the client.
D. Initiating IV access is the priority because the client is showing signs of early hypovolemic shock (tachycardia, low-normal blood pressure). Rapid IV access allows for fluid resuscitation and administration of blood products if needed, stabilizing both maternal and fetal status before other interventions.
