A nurse is preparing to percuss an adolescent's chest and abdomen. Which of the following areas should the nurse expect to hear a dull sound? (You will find hot spots to select in the artwork below. Select only the hot spot that corresponds to your answer.)

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.

A: By the age of 7, most children have a grasp of days and dates as part of their routine. However, not being able to verbalize the date does not necessarily indicate a developmental delay, as it could be related to the child's learning environment or educational opportunities.

B: Counting backwards is a skill that develops with age and practice. A 7-year-old may struggle with this task due to various reasons such as lack of practice, but it is not a definitive sign of a developmental delay.

C: Making change involves complex cognitive skills including math, understanding of money value, and transactions, which may still be developing in a 7-year-old. This skill varies widely among children and is influenced by their experiences with money.

D: The ability to distinguish right from left is a developmental milestone typically achieved by the age of 5 to 6 years. Persistent difficulty in telling the difference between right and left at the age of 7 could suggest a developmental delay in spatial awareness.
