A nurse is caring for a laboring person who is in the first stage of labor. What is the priority assessment to perform during this stage?
- A. monitor vital signs
- B. perform a vaginal exam
- C. perform a cervical check
- D. monitor the fetal heart rate
Correct Answer: A
Rationale: The correct answer is A: monitor vital signs. During the first stage of labor, it is crucial to monitor the laboring person's vital signs to assess for any signs of distress or complications. This includes monitoring blood pressure, pulse rate, respiratory rate, and temperature. By closely monitoring vital signs, the nurse can identify any potential issues early on and take appropriate actions to ensure the safety and well-being of both the laboring person and the baby. Performing a vaginal exam (B) or cervical check (C) may be necessary later in labor but is not the priority assessment during the first stage. Monitoring the fetal heart rate (D) is also important but not the priority over monitoring the laboring person's vital signs.
What is the first step the nurse should take when assessing a newborn's respiratory status immediately after birth?
- A. observe for respiratory effort
- B. take the newborn's temperature
- C. assist with suctioning the airways
- D. suction the newborn's mouth
Correct Answer: A
Rationale: The correct answer is A: observe for respiratory effort. This is the first step because it helps the nurse quickly assess if the newborn is breathing effectively. Observing for respiratory effort allows for prompt identification of any potential respiratory distress or abnormalities. Taking the newborn's temperature (B) is important but not the first step in assessing respiratory status. Assisting with suctioning the airways (C) should only be done if there are signs of airway obstruction, not as the initial step. Suctioning the newborn's mouth (D) is not recommended immediately after birth unless there is clear obstruction, as this can stimulate unnecessary reflexes and cause harm.
A multigravid client is 22 weeks pregnant. Which of the following symptoms would the nurse expect the client to exhibit?
- A. Nausea.
- B. Dyspnea.
- C. Urinary frequency.
- D. Leg cramping.

Rationale: Leg cramping is a common complaint during the second trimester. Nausea is more common in the first trimester, and dyspnea and urinary frequency are more common in the third trimester.
A pregnant patient at 32 weeks gestation reports a sudden headache and blurred vision. What is the nurse's priority action?
- A. Assess the patient's blood pressure and check for signs of preeclampsia.
- B. Administer pain medication and advise the patient to rest.
- C. Encourage the patient to drink fluids and take deep breaths.
- D. Perform a visual acuity test and schedule a follow-up appointment.
Correct Answer: A
Rationale: The correct answer is A: Assess the patient's blood pressure and check for signs of preeclampsia. This is the priority action because sudden headache and blurred vision are symptoms of preeclampsia, a serious condition in pregnancy. Step 1: Assessing blood pressure is crucial to identify hypertension, a hallmark of preeclampsia. Step 2: Checking for other signs of preeclampsia, such as proteinuria and edema, helps confirm the diagnosis. Step 3: Prompt intervention is necessary to prevent complications for both the mother and the baby. Choices B, C, and D are incorrect because they do not address the potential life-threatening condition of preeclampsia and may delay appropriate treatment.
