Among toddlers and children up to age five, femur fractures usually result from a low energy fall. In most cases, the orthopedic surgeon realigns the fractureusing fluoroscopy or x-ray imaging as a guide and immobilizes the leg in a type of cast called a spica cast. Approximately how many weeks does it take for a fractured femur to heal in a 3-year-old?
- A. 2 weeks
- B. 4 weeks
- C. 8 weeks
- D. 10 weeks
Correct Answer: C
Rationale: In general, it takes approximately 6 to 8 weeks for a fractured femur in a 3-year-old child to heal. Children tend to heal faster than adults due to their higher metabolism and more robust bone growth. The spica cast helps stabilize the fracture and provides the necessary support for proper healing. Regular monitoring through x-ray imaging ensures the healing progress and guides the decision for cast removal.

A patient develops a postoperative deep vein thrombosis and is started on IV heparin. Which of the ff. laboratory tests is monitored during the heparin therapy?
- A. Plasma fibrinogen c.Partial thromboplastin time (PTT)
- B. Prothrombin time (PT)
- C. International normalized ratio (INR)
Correct Answer: C
Rationale: During heparin therapy, the laboratory test that is monitored is the partial thromboplastin time (PTT). Heparin acts by potentiating the activity of antithrombin III, leading to the inhibition of both thrombin and factor Xa. The PTT measures the intrinsic pathway of coagulation and is prolonged with heparin due to its anticoagulant effect. Monitoring the PTT helps to ensure that the patient is within the therapeutic range of anticoagulation to prevent clot formation without increasing the risk of bleeding complications. Plasma fibrinogen, prothrombin time (PT), and international normalized ratio (INR) are not routinely monitored during heparin therapy.
