A nurse is reinforcing teaching with the guardian of a 1-month-old infant who has colic.
Which of the following instructions should the nurse include in the teaching?

Rationale:

A. Monitoring capillary refill of the casted extremity is crucial for assessing circulation and ensuring there are no complications such as compartment syndrome.

B. While supporting the cast correctly is important, it is not the priority immediately following the application.

C. Examining the skin at the cast edges is important, but it is not the priority immediately following the application.

D. Instructing the child not to put anything inside the cast is important, but it is not the priority immediately following the application.

Rationale:

A) Using the index finger is a common site for blood glucose monitoring, but it does not specifically address minimizing pain.

B) Holding the finger under warm water can increase blood flow and make blood glucose monitoring less painful.

C) Puncturing the center of the finger pad is a common technique for obtaining a blood sample, but it does not specifically address minimizing pain.

D) Holding the finger against a table is not a recommended method for minimizing pain during blood glucose monitoring and may increase discomfort.
