A nurse is teaching a newly licensed nurse about the difference between a plaster cast and a synthetic cast. Which of the following information should the nurse include in the teaching?
Drying time is prolonged with a synthetic cast.
A synthetic cast is weighs less.
A plaster cast requires expensive equipment for application.
A synthetic case immobilizes bone fractures more effectively.
The Correct Answer is B
A. This statement is incorrect. Drying time is actually shorter with a synthetic cast compared to a plaster cast. Synthetic casts use a chemical reaction for hardening, which typically sets faster than the drying process of plaster.
B. Correct. A synthetic cast is generally lighter in weight compared to a plaster cast. This can be more comfortable for the patient and may provide better mobility.
C. This statement is incorrect. Plaster casts do not necessarily require expensive equipment for application. Both types of casts require appropriate materials and training for application, but cost can vary based on factors like the type of material and the specific clinical setting.
D. This statement is incorrect. Both plaster and synthetic casts are effective for immobilizing bone fractures when applied correctly. The choice between the two often depends on factors such as the type of fracture, patient comfort, and clinician preference.

Correct Answer is ["B","C","D"]
Explanation
A. Position weights against the foot of the bed: Incorrect. Weights in Buck's traction are typically hung freely over the end of the bed to provide the necessary countertraction. Placing them against the foot of the bed would not serve this purpose.
B. Examine the skin under the traction splint: Correct. It's important to regularly assess the skin underneath the traction splint to ensure there are no signs of pressure ulcers or skin breakdown.
C. Monitor peripheral pulses in the affected extremity: Correct. This is essential to ensure that blood flow to the extremity is not compromised by the traction.
D. Assess the temperature of the affected extremity: Correct. Monitoring the temperature helps in identifying any signs of impaired circulation.
E. Adjust the prescribed weights every shift: This is not something that should be done without specific orders from the healthcare provider. Adjusting the weights should be done based on the specific plan of care and provider's instructions.
Correct Answer is D
Explanation
A. Cool extremities are not typically associated with carpal tunnel syndrome. They may be a sign of poor circulation, but this is not a specific finding for carpal tunnel syndrome.
B. Decreased radial pulse is not a characteristic finding of carpal tunnel syndrome. It may indicate issues with blood flow to the hand but is not specific to this condition.
C. Positive Chvostek's sign is associated with hypocalcemia and involves facial muscle twitching when the facial nerve is tapped. It is not related to carpal tunnel syndrome.
D. Positive Phalen's sign is a characteristic finding in carpal tunnel syndrome. It involves tingling or numbness in the median nerve distribution (usually thumb, index, middle, and part of the ring finger) when the wrist is flexed for 60 seconds.
