A nurse in the newborn nursery, assisting with data collection for a newborn, prepares to measure the chest circumference. The nurse places the tape measure around the infant at which location?
- A. In the axillary area
- B. At the level of the nipples
- C. Two inches below the nipples
- D. At the level of the umbilicus
Correct Answer: B
Rationale: The chest circumference of the infant is measured at the level of the nipples. It is usually 2 to 3 cm smaller than the head circumference. The average chest circumference is 30.5 to 33 cm (12-13 inches). When there is molding of the head, the head and chest measurements may be equal at birth. Placing the tape measure at the level of the nipples ensures accuracy and consistency in newborn assessment. Options A, C, and D are incorrect as the chest circumference is specifically measured at the level of the nipples to obtain precise measurements.
When a 16-year-old girl visits the women's health clinic to obtain information about birth control because she is sexually active and wants to avoid pregnancy, what should the nurse do first when interviewing the client?
- A. Assess the client's knowledge of available birth control methods.
- B. Inform the client that birth control methods can be discussed without the client's boyfriend present.
- C. Tell the client that for her age and lifestyle, birth control pills would be one of the methods of contraception.
- D. Give the client written material about various birth control methods and ask her to read them and to call if she has any questions.
Correct Answer: A
Rationale: When a client seeks information about birth control, it is essential for the nurse to first assess the client's existing knowledge on the subject. This enables the nurse to provide tailored information that complements what the client already knows, facilitating better understanding and decision-making. Providing written material is a helpful educational tool but should not be the first intervention. Offering specific advice on birth control methods based on age and lifestyle limits the client's autonomy and decision-making process. Mentioning the client's boyfriend as a requirement for discussing birth control is inappropriate and nontherapeutic, as the client should be able to seek information independently.
When teaching parents how their children learn sex role identification, the nurse should include which of the following statements?
- A. Sex role identification begins in infancy.
- B. Sex role identification begins in the preschool years.
- C. Sex role identification begins during the school-age years.
- D. Sex role identification begins during early adolescence.
Correct Answer: A
Rationale: Sex role identification begins during infancy as infants can identify body parts by the end of the first year. Preschoolers often engage in masturbation and sex play. School-age children continue to develop awareness of their sexual identity, including behaviors like hugging and kissing. Early adolescence sees further development influenced by sexual maturation and experimentation with sex roles. Therefore, the correct statement is that sex role identification begins in infancy. Choices B, C, and D are incorrect as they misrepresent the timeline of the development of sex role identification in children.
A nurse assisting with data collection plans to assess tactile (vocal) fremitus. The nurse performs this by using which technique?
- A. Palpating for symmetric chest expansion
- B. Auscultating the breath sounds over the trachea and larynx
- C. Auscultating the breath sounds over the peripheral lung fields
- D. Palpating the thorax, comparing vibrations from side to side as the client repeats the word 'ninety-nine'
Correct Answer: D
Rationale: To assess tactile (vocal) fremitus, the nurse palpates the thorax and compares vibrations from side to side as the client repeats the word 'ninety-nine.' This technique helps in evaluating the intensity and symmetry of vibrations felt. Palpating for symmetric chest expansion involves assessing the expansion of the chest during breathing by placing hands on the anterolateral wall. Auscultating the breath sounds over the trachea and larynx is done to assess bronchial breath sounds, while auscultating over the peripheral lung fields is used to assess vesicular breath sounds.
At what age are yearly mammograms recommended to start?
- A. Yearly mammograms are recommended starting at age 25.
- B. Yearly mammograms are recommended starting at age 40.
- C. Yearly mammograms are not necessary unless there is a family history of breast cancer.
- D. Yearly mammograms are recommended starting at age 20 and continuing until menopause begins.
Correct Answer: B
Rationale: The correct answer is B. The American Cancer Society recommends yearly mammograms starting at age 40 and continuing for as long as a woman is in good health. Clinical breast examination should be done about every 3 years for women in their 20s and 30s and every year for women age 40 and older. Women should know how their breasts normally look and feel and report any breast change promptly to the healthcare provider. Breast self-examination should be done monthly starting when a woman is in her 20s. Choice A is incorrect as mammograms are not recommended to start at age 25. Choice C is incorrect as yearly mammograms are still recommended even without a family history of breast cancer. Choice D is incorrect as the recommended age for starting yearly mammograms is 40, not 20.
