The nurse is seeing an adolescent and the parents in the clinic for the first time. Which should the nurse do first?
- A. Introduce him- or herself.
- B. Make the family comfortable.
- C. Give assurance of privacy.
- D. Explain the purpose of the interview.
Correct Answer: A
Rationale: The first thing that nurses must do is to introduce themselves to the patient and family. Parents and other adults should be addressed with appropriate titles unless they specify a preferred name. Clarification of the purpose of the interview and the nurses role is the second thing that should be done. During the initial part of the interview, the nurse should include general conversation to help make the family feel at ease. The interview also should take place in an environment as free of distraction as possible. In addition, the nurse should clarify which information will be shared with other members of the health care team and any limits to the confidentiality.
The nurse is preparing to perform a physical assessment on a 10-year-old girl. The nurse gives her the option of her mother staying in the room or leaving. This action should be considered which?
- A. Appropriate because of childs age
- B. Appropriate, but the mother may be uncomfortable
- C. Inappropriate because of childs age
- D. Inappropriate because child is same sex as mother
Correct Answer: A
Rationale: It is appropriate to give older school-age children the option of having the parent present or not. During the examination, the nurse should respect the childs need for privacy. Children who are 10 years old are minors, and parents are responsible for health care decisions. The mother of a 10-year-old child would not be uncomfortable. The child should help determine who is present during the examination.

With the National Center for Health Statistics criteria, which body mass index (BMI)-for-age percentiles should indicate the patient is at risk for being overweight?
- A. 10th percentile
- B. 75th percentile
- C. 85th percentile
- D. 95th percentile
Correct Answer: C
Rationale: Children who have BMI-for-age greater than or equal to the 85th percentile and less than the 95th percentile are at risk for being overweight. Children who are greater than or equal to the 95th percentile are considered overweight. Children whose BMI is between the 10th and 75th percentiles are within normal limits.
During a routine health assessment, the nurse notes that an 8-month-old infant has a significant head lag. Which is the most appropriate action?
- A. Recheck head control at next visit.
- B. Teach the parents appropriate exercises.
- C. Schedule the child for further evaluation.
- D. Refer the child for further evaluation if the anterior fontanel is still open.
