A healthcare provider is assessing a newborn 1 hr after birth. Which of the following respiratory rates is within the expected reference range for a newborn?
- A. 22/min
- B. 48/min
- C. 100/min
- D. 110/min
Correct Answer: B
Rationale: The correct answer is B: 48/min. The normal respiratory rate for a newborn is typically between 30-60 breaths per minute. It is important to assess a newborn's respiratory rate to ensure proper oxygenation. Option A (22/min) is too low, while options C (100/min) and D (110/min) are too high and could indicate respiratory distress or other issues that need immediate attention. Therefore, option B falls within the expected reference range and is the correct answer for a healthy newborn assessment.

A client who is breastfeeding and has mastitis is receiving teaching from the nurse. Which of the following responses should the nurse make?
- A. Limit the amount of time the infant nurses on each breast.
- B. Nurse the infant only on the unaffected breast until resolved.
- C. Completely empty each breast at each feeding or use a pump.
- D. Wear a tight-fitting bra until lactation has ceased.
Correct Answer: C
Rationale: The correct answer is C: Completely empty each breast at each feeding or use a pump. This is the correct response because it helps to ensure effective milk removal, which is crucial for treating mastitis. By fully emptying the breast, the nurse can prevent milk stasis and promote healing.
A: Limiting the time the infant nurses on each breast may lead to incomplete milk removal, worsening the condition.
B: Nursing only on the unaffected breast does not address the issue of milk stasis in the affected breast and may lead to further complications.
D: Wearing a tight-fitting bra can exacerbate mastitis by restricting milk flow and increasing discomfort.
When should a provider order a maternal serum alpha-fetoprotein (MSAFP) screening for pregnant clients?
- A. A client who has mitral valve prolapse
- B. A client who has been exposed to AIDS
- C. All pregnant clients
- D. A client who has a history of preterm labor
Correct Answer: C
Rationale: Rationale:
- MSAFP screening is recommended for all pregnant clients to assess risk of neural tube defects or chromosomal abnormalities.
- It is a standard prenatal test regardless of specific medical conditions.
- Options A, B, and D are not directly related to the indication for MSAFP screening in pregnancy.
When assisting a client with breastfeeding, which of the following reflexes will promote the newborn to latch?
- A. Babinski
- B. Rooting
- C. Moro
- D. Stepping
Correct Answer: B
Rationale: The correct answer is B: Rooting. This reflex helps the newborn turn their head towards a stimulus, such as the mother's nipple, facilitating latching during breastfeeding. Babinski (A) is a reflex related to the sole of the foot, Moro (C) is a startle reflex, and Stepping (D) involves movements resembling walking. These reflexes do not directly support the latch during breastfeeding. Rooting reflex is the most relevant and essential reflex for successful breastfeeding initiation.
A newborn who was born at 38 weeks of gestation, weighs 3,200 g, and is in the 60th percentile for weight should be classified as which of the following?
- A. Low birth weight
- B. Appropriate for gestational age
- C. Small for gestational age
- D. Large for gestational age
Correct Answer: B
Rationale: The correct answer is B: Appropriate for gestational age. A newborn is considered appropriate for gestational age when their weight falls within the 10th to 90th percentiles for their gestational age. In this case, the newborn is in the 60th percentile for weight, indicating that the weight is appropriate for the gestational age of 38 weeks.
Choice A: Low birth weight is incorrect because a newborn is classified as low birth weight when their weight is below 2,500 g regardless of gestational age.
Choice C: Small for gestational age is incorrect because a newborn is classified as small for gestational age when their weight is below the 10th percentile for their gestational age.
Choice D: Large for gestational age is incorrect because a newborn is classified as large for gestational age when their weight is above the 90th percentile for their gestational age.
During an assessment, a healthcare provider observes small pearly white nodules on the roof of a newborn's mouth. This finding is a characteristic of which of the following conditions?
- A. Mongolian spots
- B. Milia spots
- C. Erythema toxicum
- D. Epstein's pearls
Correct Answer: D
Rationale: The correct answer is D: Epstein's pearls. These small pearly white nodules are commonly found on the roof of newborns' mouths and are considered a normal finding. They are formed from trapped epithelial cells during the development of the baby's mouth. They are harmless and typically resolve on their own without treatment.
A: Mongolian spots are bluish-black or bruise-like markings found on the skin, not in the mouth.
B: Milia spots are small, white, raised bumps on the skin, not found in the mouth.
C: Erythema toxicum is a common benign rash in newborns, not related to the mouth.
In summary, Epstein's pearls are the correct answer due to their specific location in the newborn's mouth, their appearance, and the fact that they are a normal finding in newborns. The other choices are incorrect as they describe different conditions not related to the oral cavity.
