Explanation
A. "The blood supply to the bone is disrupted." – Incorrect. While fractures can affect blood flow, the main concern with epiphyseal plate fractures is growth impairment.
B. "The younger the child, the longer the healing process will take." – Incorrect. Younger children heal faster than older children or adults due to active bone remodeling.
C. "Bone marrow can be lost through the fracture." – Incorrect. Epiphyseal fractures do not cause bone marrow loss.
D. "Normal bone growth can be affected." – Correct. The epiphyseal plate is responsible for bone growth, and injury to this area can lead to growth disturbances or limb length discrepancies.
Correct Answer is ["70"]
Explanation
The nurse should withhold digoxin if the child's apical heart rate is less than 70 beats per minute because digoxin slows the conduction of electrical signals in the heart and increases the force of cardiac contraction. While this helps to treat conditions like heart failure and arrhythmias, it can also lead to bradycardia. Administering digoxin when the heart rate is already too low increases the risk of adverse effects like severe bradycardia or even cardiac arrest.
