Correct Answer: B

Rationale: The expected respiratory rate for a newborn is between 30 to 60 breaths per minute. A rate of 48 breaths per minute falls within this range, indicating normal respiratory function for a newborn. Choice A (22/min) is below the expected range, Choices C (100/min) and D (110/min) are above the expected range for a newborn's respiratory rate.

Correct Answer: C

Rationale: Maternal serum alpha-fetoprotein (MSAFP) screening is recommended for all pregnant clients to assess the risk of neural tube defects. It is a routine screening test used to detect increased levels of alpha-fetoprotein in maternal blood, which may indicate a higher risk for conditions such as neural tube defects in the developing fetus. Therefore, all pregnant clients, regardless of their medical history or risk factors, should undergo MSAFP screening as part of routine prenatal care. Choices A, B, and D are incorrect because the MSAFP screening is not specific to certain medical conditions or histories; it is a standard screening procedure for all pregnant individuals to evaluate neural tube defect risk in the fetus.

Correct Answer: A

Rationale: The correct treatment for chlamydia is a one-time dose of azithromycin. It is crucial for the client to understand the correct medication regimen for effective treatment. Choice B is incorrect because treatment is necessary for the partner even if asymptomatic. Choice C is incorrect because sexual relations should be avoided until treatment is completed. Choice D is incorrect as retesting should generally occur 3 months after treatment.

Correct Answer: A

Rationale: A bluish-brown marking across the lower back is more commonly seen in newborns with dark skin. These markings are known as Mongolian spots and are benign. They are not related to hyperbilirubinemia, forceps marks, or trauma during delivery. Choice B is incorrect because hyperbilirubinemia presents as jaundice, not as a bluish-brown marking. Choice C is incorrect because forceps marks would have a different appearance and location. Choice D is incorrect as Mongolian spots are not related to prolonged birth or trauma during delivery.

Correct Answer: B

Rationale: The priority action for the nurse in this situation is to position the client with one hip elevated. This position can help improve blood flow to the placenta and stabilize blood pressure, which is crucial for both the client and the fetus during labor. It can also help optimize fetal oxygenation by improving circulation. Notifying the provider of the findings may be necessary, but ensuring proper positioning of the client takes precedence to address the immediate physiological needs. Asking the client about pain medication or having the client void are important interventions but are not the priority in this scenario where the client is experiencing painful contractions and has low blood pressure.
