A pregnant client tells the clinic nurse she wants to know the sex of her baby as soon as it can be determined. What factor allows this at 12 weeks' gestation?

Correct Answer: A

Rationale: By 12 weeks, the external genitalia are sufficiently developed for visual determination of the baby's sex.

Correct Answer: B

Rationale: Prolonged stress and systemic racism contribute to higher rates of preeclampsia in Black pregnant individuals.

Correct Answer: D

Rationale: A severe headache postpartum can indicate preeclampsia or other serious conditions requiring immediate action.

Correct Answer: A

Rationale: Nasal flaring in a newborn can be a sign of respiratory distress, which is a critical condition that requires immediate attention. It indicates that the newborn is having difficulty breathing and may not be getting enough oxygen. This can be due to various reasons such as lung problems, infections, or other respiratory issues. Therefore, the nurse should assess and address the newborn with nasal flaring first to ensure their breathing is stable and adequate.

Correct Answer: C

Rationale: A client with hyperemesis gravidarum and a sodium level of 110 mEq/L is at risk for severe dehydration and electrolyte imbalance, particularly hyponatremia (low sodium level). Hyponatremia can lead to serious complications such as seizures, coma, and even death if not promptly addressed. Therefore, this client should be assessed first to prevent any potential life-threatening conditions. The nurse should prioritize interventions to address the electrolyte imbalance and dehydration in this client to ensure their safety and well-being.

Correct Answer: B

Rationale: Lightheadedness and nausea can be signs of hypotension, a common side effect of epidural anesthesia.

Correct Answer: A

Rationale: Hyperemesis gravidarum is a severe form of nausea and vomiting during pregnancy that can lead to dehydration and electrolyte imbalances. One important laboratory test that the nurse should anticipate for a client with hyperemesis gravidarum is the urine ketones test. Ketones in the urine can indicate that the body is breaking down fat for energy instead of using glucose, which can occur during prolonged fasting or in conditions like hyperemesis gravidarum where there is severe vomiting leading to inadequate intake of nutrients. Monitoring urine ketones levels helps healthcare providers assess the severity of dehydration and metabolic derangement in these patients. It guides the management of fluid and electrolyte replacement to prevent complications like ketosis and metabolic acidosis.

Correct Answer: D

Rationale: As women age, their ovarian reserve decreases and the quality of their eggs declines, making it more difficult to conceive. This is due to the normal aging process of the ovaries, which can lead to decreased fertility and an increased risk of chromosomal abnormalities in the embryos. Therefore, a patient who is older than 35 years may have difficulty achieving pregnancy because the ovaries may be affected by the normal aging process.

Correct Answer: B

Rationale: GBS testing is typically performed between 35–37 weeks to identify and manage infection risks during delivery.
