A pregnant patient at 34 weeks gestation is concerned about the possibility of preterm labor. Which of the following is the most appropriate action for the nurse to take?
- A. Monitor the fetal heart rate and check for signs of labor.
- B. Administer magnesium sulfate to prevent contractions.
- C. Encourage the patient to rest and monitor for changes in symptoms.
- D. Recommend that the patient lie flat on her back for 24 hours.
Correct Answer: A
Rationale: The correct answer is A. Monitoring the fetal heart rate and checking for signs of labor is the most appropriate action as it allows the nurse to assess the status of the pregnancy and the potential onset of preterm labor. This proactive approach helps in early identification and management of any concerning signs or symptoms. Administering magnesium sulfate (choice B) is not appropriate without proper assessment and indication. Encouraging rest and symptom monitoring (choice C) is beneficial but may not be sufficient for evaluating preterm labor. Recommending the patient lie flat on her back for 24 hours (choice D) is not evidence-based and could potentially cause harm.

A nurse is assessing a laboring person who is receiving oxytocin for labor induction. What is the most important intervention to prevent uterine hyperstimulation?
- A. monitor fetal heart rate
- B. increase fetal monitoring
- C. administer an epidural
- D. monitor contractions
Correct Answer: B
Rationale: The correct answer is B: increase fetal monitoring. Monitoring the fetus closely is crucial to detect signs of uterine hyperstimulation, such as non-reassuring fetal heart rate patterns. This allows for timely interventions to prevent fetal distress or hypoxia. Monitoring contractions (choice D) is important but does not directly address fetal well-being. Administering an epidural (choice C) may help manage pain but does not prevent uterine hyperstimulation. While monitoring fetal heart rate (choice A) is important, increasing the frequency of monitoring (choice B) is more specific to detecting complications related to oxytocin-induced uterine hyperstimulation.
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.
Correct Answer: D
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 client enters the prenatal clinic. She states that she believes she is pregnant. Which of the following hormone elevations will indicate a high probability that the client is pregnant?
- A. Chorionic gonadotropin.
- B. Oxytocin.
- C. Prolactin.
- D. Luteinizing hormone.
Correct Answer: A
Rationale: Chorionic gonadotropin (hCG) is the hormone detected by pregnancy tests and is a definitive indicator of pregnancy. Oxytocin, prolactin, and luteinizing hormone are not specific to pregnancy.
A nurse is educating a postpartum person about newborn care. What is the best way to prevent diaper rash?
- A. frequent diaper changes
- B. use of a barrier cream
- C. apply petroleum jelly to the skin
- D. change diapers frequently
Correct Answer: C
Rationale: The correct answer is C: apply petroleum jelly to the skin. Petroleum jelly acts as a barrier, protecting the baby's skin from moisture and irritants in the diaper. It helps maintain the skin's natural moisture and prevents diaper rash.
Rationale:
1. Petroleum jelly creates a protective barrier on the skin, preventing direct contact with moisture and irritants.
2. It helps to keep the skin moisturized, reducing the risk of irritation.
3. Petroleum jelly is safe and gentle on the baby's skin.
4. It is particularly effective for preventing diaper rash compared to other options.
Summary:
A: Frequent diaper changes are important but may not provide enough protection against moisture and irritants.
B: Barrier creams can be effective, but petroleum jelly is a more commonly recommended option.
D: Changing diapers frequently is essential, but applying petroleum jelly as an additional protective measure is more effective in preventing diaper rash.
The nurse explains that prior to fertilization each cell is reduced from 46 chromosomes to 23 chromosomes. This is referred to as the __________ number.
- A. haploid
- B. DNA
- C. Chromoses
- D. Plastoderm
Correct Answer: A
Rationale: Prior to fertilization, each cell undergoes meiosis, reducing its chromosome count from 46 to 23. This reduction ensures genetic diversity and proper development of the embryo. The term 'haploid' refers to cells containing only one set of chromosomes.
