Nursing Elites

1. 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?

• A. Contraction durations of 95 to 100 seconds
• B. Contraction frequency of 2 to 3 minutes apart
• C. Absent early deceleration of fetal heart rate
• D. Fetal heart rate is 140/min

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.

2. When assessing a woman in the first stage of labor, which clinical finding will alert the nurse that uterine contractions are effective?

• A. Dilation of the cervix.
• B. Descent of the fetus to –2 station.
• C. Rupture of the amniotic membranes.
• D. Increase in bloody show.

Correct answer: A

Rationale: During the first stage of labor, effective uterine contractions lead to cervical dilation. Dilation of the cervix is a key indicator that uterine contractions are progressing labor. Descent of the fetus to -2 station (Choice B) is related to the fetal position in the pelvis and not a direct indicator of uterine contraction effectiveness. Rupture of the amniotic membranes (Choice C) signifies the rupture of the fluid-filled sac surrounding the fetus and does not directly reflect uterine contraction effectiveness. An increase in bloody show (Choice D) can be a sign of impending labor, but it is not a direct indicator of uterine contraction effectiveness.

3. How many chromosomes are typically found in human cells, organized into pairs?

• A. 50
• B. 46
• C. 48
• D. 44

Correct answer: B

Rationale: Human cells typically contain 46 chromosomes organized into 23 pairs. This is the correct number for a normal human cell. Choices A, C, and D are incorrect because they do not represent the typical chromosome count in human cells.

4. Which of the following is a fatal genetic neurologic disorder whose onset is in middle age?

• A. Tay-Sachs disease
• B. Duchenne muscular dystrophy
• C. Hemophilia
• D. Huntington’s disease

Correct answer: D

Rationale: Huntington's disease is a fatal genetic neurologic disorder characterized by progressive nerve cell degeneration in the brain. It typically manifests in middle age with symptoms such as involuntary movements, cognitive decline, and psychiatric disturbances. Tay-Sachs disease (Choice A) is a genetic disorder that primarily affects the nervous system in early childhood, not middle age. Duchenne muscular dystrophy (Choice B) is a genetic disorder that primarily affects muscle function and usually presents in early childhood. Hemophilia (Choice C) is a genetic disorder related to blood clotting, and its onset is not typically in middle age.

5. In the context of an average ejaculation, which of the following statements is true about sperm?

• A. The average count of sperm in the ejaculate is 2.5 billion.
• B. Sperm in the ejaculate find the ovum by following the current of the fluid coming from the cervix.
• C. Only 1 in 1,000 sperm in the ejaculate will ever approach an ovum.
• D. Most of the sperm in the ejaculate move about in a random pattern in the vagina.

Correct answer: C

Rationale: Out of millions of sperm released during ejaculation, only a small fraction, about 1 in 1,000, will approach the ovum. This statement is true as sperm face many obstacles and challenges on their journey to reach and fertilize an ovum. Choice A is incorrect because the average count of sperm in an ejaculate is typically in the millions, not billions. Choice B is incorrect as sperm do not find the ovum by following the current of fluid; they navigate using other mechanisms. Choice D is incorrect because while some sperm may move randomly in the vagina, the ones that approach the ovum do so through a more purposeful and directed movement.
