The mother of a newborn who was circumcised before discharge from the hospital calls the nurse at the pediatrician's office and tells the nurse that she is concerned because she has noticed a yellow crust over the circumcision site. The nurse provides which information to the mother?

Correct Answer: B

Rationale: After circumcision, a yellow crust may form over the circumcision site, which is a normal part of healing and should not be removed. The mother should be reassured that this crust is to be expected. Yellow crusting or discharge is not indicative of an infection, and there is no need to notify the pediatrician. Checking the infant's temperature every 2 hours is unnecessary and may cause unnecessary alarm to the mother.

Correct Answer: C

Rationale: Breastfed infants pass very soft, seedy, mustard-yellow stools, which is considered normal. Formula-fed infants excrete stools that are more solid and pale yellow to light brown. It is essential for the mother to understand that seedy, mustard-yellow stools are expected in breastfed infants, indicating that there is no need for concern. Monitoring for infection as the first response without other symptoms can cause unnecessary anxiety. Decreasing the number of feedings without valid reasons can lead to inadequate nutrition for the newborn. Therefore, the correct advice for the nurse to provide in this scenario is that seedy, mustard-yellow stools are normal for breastfed infants, reassuring the mother and promoting proper understanding of newborn stool characteristics.

Correct Answer: D

Rationale: When preparing to listen to a client's breath sounds, a nurse should ask the client to sit and lean forward slightly, with the arms resting comfortably across the lap. The client should be instructed to breathe through the mouth a little more deeply than usual but to stop if feeling dizzy. The nurse should use the flat diaphragm end-piece of the stethoscope, holding it firmly on the chest wall. By using the diaphragm, the nurse can listen for at least one full respiration in each location, moving from side to side to compare sounds. This technique ensures a systematic and thorough assessment of lung sounds. Choice A is correct as it includes the proper positioning of the client and specifies the use of the diaphragm of the stethoscope. Choice B is incorrect as both lungs should be auscultated systematically, starting from the top and moving down. Choice C is incorrect as deep breaths, not shallow ones, are recommended for an accurate assessment of breath sounds.

Correct Answer: D

Rationale: To assess vesicular breath sounds, the nurse should place the stethoscope over the peripheral lung fields. Vesicular breath sounds are heard in these areas where air flows through the smaller bronchioles and alveoli. Bronchovesicular breath sounds, not vesicular, are heard over the major bronchi. Bronchial (tracheal) breath sounds are heard over the trachea and larynx, not vesicular sounds. Breath sounds are not heard over the xiphoid process, making it an incorrect choice.

Correct Answer: D

Rationale: Before administering the hepatitis B vaccine to a newborn infant, the nurse must obtain parental consent. Hepatitis B vaccine is typically given at birth, 1 month, and 6 months of age. Checking the infant for jaundice, checking the temperature, and requesting a hepatitis blood screen are unnecessary in this context. Parental consent is crucial for any medical intervention involving minors.
