1. Humans begin life as a single cell that divides repeatedly. This cell is known as a(n):

Correct answer: A

Rationale: A zygote is the correct answer. It is the initial cell formed when a sperm cell fertilizes an egg cell, marking the beginning of human development. Choice B, gonadotrope, is incorrect as it refers to a type of hormone-secreting cell in the pituitary gland. Choice C, embryo, is incorrect as it is the stage of development after the zygote has implanted into the uterine wall and undergone initial cell divisions. Choice D, chromaffin, is incorrect as it refers to cells found in the adrenal medulla that produce and store catecholamines.

2. A charge nurse is teaching a group of staff nurses about fetal monitoring during labor. Which of the following findings should the charge nurse instruct the staff members to report to the provider?

Correct answer: A

Rationale: The correct answer is A. Contraction durations of 95 to 100 seconds are prolonged, indicating uterine hyperstimulation, which can lead to fetal distress and requires immediate intervention. Reporting this finding to the provider is crucial to ensure timely management and prevent adverse outcomes. Choice B, contraction frequency of 2 to 3 minutes apart, is within the normal range and does not raise immediate concerns. Choice C, absent early deceleration of fetal heart rate, is a reassuring finding suggesting fetal well-being. Choice D, a fetal heart rate of 140/min, is also normal for a fetus and does not typically require immediate reporting unless it deviates significantly from the baseline or is accompanied by other concerning signs.

3. In the Ballard Gestational Age Assessment Tool, the nurse determines that a 15-month-old infant has a gestational age of 42 weeks. Based on this finding, which intervention is most important for the nurse to implement?

Correct answer: B

Rationale: Late preterm infants, such as those with a gestational age of 42 weeks, are at higher risk for hypoglycemia due to immature metabolic regulation. Monitoring capillary blood glucose is crucial to detect and manage hypoglycemia promptly. Providing blow-by oxygen (Choice A) is not indicated for an infant at risk for hypoglycemia. Drawing arterial blood gases (Choice C) is not the primary intervention for assessing hypoglycemia. Applying a pulse oximeter to the foot (Choice D) is not directly related to monitoring blood glucose levels in this context.

4. During a prenatal visit, for which of the following clients should the nurse auscultate the fetal heart rate?

Correct answer: D

Rationale: The correct answer is D because feeling quickening typically occurs around 18-20 weeks of gestation, indicating fetal movement. This is an appropriate time to auscultate the fetal heart rate. Choice A is incorrect because a molar pregnancy is not a viable pregnancy, and auscultating the fetal heart rate in this case is not applicable. Choice B is incorrect because a crown-rump length of 7 weeks gestation is too early for fetal heart rate auscultation. Choice C is incorrect because a positive urine pregnancy test alone does not indicate the appropriate timing for fetal heart rate auscultation.

5. A healthcare provider is assessing a newborn immediately following a vaginal birth. For which of the following findings should the provider intervene?

Correct answer: D

Rationale: Sternal retractions in a newborn indicate respiratory distress and require immediate intervention. This finding suggests the newborn is having difficulty breathing and needs prompt attention to ensure adequate oxygenation. Molding, the overlapping of fetal skull bones during birth, is a normal and expected process that does not require intervention. Vernix Caseosa, the protective white substance on the skin, and Acrocyanosis, the bluish discoloration of extremities, are both common and benign findings in newborns that do not necessitate immediate action. Therefore, the healthcare provider should focus on addressing sternal retractions to manage the respiratory distress effectively.
