What is an appropriate screening test for hearing that the nurse can administer to a 5-year-old child?
- A. Rinne test
- B. Weber test
- C. Pure tone audiometry
- D. Eliciting the startle reflex
Correct Answer: C
Rationale: Pure tone audiometry uses an audiometer that produces sounds at different volumes and pitches in the childs ears. The child is asked to respond in some way when the tone is heard in the earphone. The Rinne and Weber tests measure bone conduction of sound. Eliciting the startle reflex may be useful in infants.
Which is the single most important factor to consider when communicating with children?
- A. Presence of the childs parent
- B. Childs physical condition
- C. Childs developmental level
- D. Childs nonverbal behaviors
Correct Answer: C
Rationale: The nurse must be aware of the childs developmental stage to engage in effective communication. The use of both verbal and nonverbal communication should be appropriate to the developmental level. Nonverbal behaviors vary in importance based on the childs developmental level and physical condition. Although the childs physical condition is a consideration, developmental level is much more important. The presence of parents is important when communicating with young children but may be detrimental when speaking with adolescents.
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.
Correct Answer: C
Rationale: Significant head lag after age 6 months strongly indicates cerebral injury and is referred for further evaluation. Head control is part of normal development. Exercises will not be effective. The lack of achievement of this developmental milestone must be evaluated.
During an otoscopic examination on an infant, in which direction is the pinna pulled?
- A. Up and back
- B. Up and forward
- C. Down and back
- D. Down and forward
Correct Answer: C
Rationale: In infants and toddlers, the ear canal is curved upward. To visualize the ear canal, it is necessary to pull the pinna down and back to the 6 to 9 oclock range to straighten the canal. In children older than age 3 years and adults, the canal curves downward and forward. The pinna is pulled up and back to the 10 oclock position. Up and forward and down and forward are positions that do not facilitate visualization of the ear canal.
The nurse is preparing to assess a 10-month-old infant. He is sitting on his fathers lap and appears to be afraid of the nurse and of what might happen next. Which initial actions by the nurse should be most appropriate?
- A. Initiate a game of peek-a-boo.
- B. Ask the infants father to place the infant on the examination table.
- C. Talk softly to the infant while taking him from his father.
- D. Undress the infant while he is still sitting on his fathers lap.
Correct Answer: A
Rationale: Peek-a-boo is an excellent means of initiating communication with infants while maintaining a safe, nonthreatening distance. The child will most likely become upset if separated from his father. As much of the assessment as possible should be done with the child on the fathers lap. The nurse should have the father undress the child as needed during the examination.
