The nurse is caring for a 32-year-old pregnant patient who is 20 weeks gestation and has a BMI of 40. Which of the following conditions should the nurse monitor for more closely?
- A. Gestational diabetes and preeclampsia
- B. Hyperemesis gravidarum
- C. Iron-deficiency anemia
- D. Intrauterine growth restriction (IUGR)
Correct Answer: A
Rationale: The correct answer is A: Gestational diabetes and preeclampsia. A BMI of 40 indicates obesity, which increases the risk of developing gestational diabetes and preeclampsia. Obesity is a significant risk factor for these conditions due to the increased strain on the body during pregnancy. Gestational diabetes can lead to complications for both the mother and the baby, while preeclampsia can be life-threatening if not managed properly. Monitoring for these conditions closely is crucial in this high-risk patient.
Incorrect Choices:
B: Hyperemesis gravidarum - This condition is characterized by severe nausea and vomiting during pregnancy and is not directly related to the patient's BMI.
C: Iron-deficiency anemia - While obesity can impact iron levels, it is not the primary concern in this scenario.
D: Intrauterine growth restriction (IUGR) - While obesity can increase the risk of certain pregnancy complications, IUGR is not directly linked to the patient's
A nurse is assisting a postpartum person with breastfeeding. What is the most important factor for successful breastfeeding?
- A. frequent breastfeeding
- B. proper latch
- C. positioning
- D. administer oxytocin
Correct Answer: B
Rationale: The correct answer is B: proper latch. A proper latch is crucial for successful breastfeeding as it ensures the baby is effectively extracting milk from the breast, preventing nipple soreness and ensuring an adequate milk supply. Without a proper latch, the baby may not receive enough milk, leading to issues such as poor weight gain and frustration for both the baby and the person breastfeeding. Frequent breastfeeding (choice A) is important, but without a proper latch, it may not be effective. Positioning (choice C) is also important, but proper latch takes precedence. Administering oxytocin (choice D) is not necessary for successful breastfeeding and may have side effects.
Organize the developmental stages in the correct order. Put a comma and space between each answer choice (a, b, c, d, etc.)
- A. Zygote
- B. Morula
- C. Blastocyst
- D. Embryo
Correct Answer: B
Rationale: Fetal development progresses through several stages: zygote, morula, blastocyst, embryo, and fetus. Each stage represents a critical phase in the formation and growth of the embryo.
A 22-year-old woman presents to the labor and delivery unit in labor at 39 weeks gestation. Her cervix is 6 cm dilated and 100% effaced. What should the nurse do next?
- A. Prepare for delivery
- B. Administer pain relief medications
- C. Continue to monitor contractions and fetal heart rate
- D. Perform a vaginal examination to check for fetal descent
Correct Answer: C
Rationale: The correct answer is C: Continue to monitor contractions and fetal heart rate. At 6 cm dilated and 100% effaced, the woman is in active labor, but delivery is not imminent. Monitoring contractions and fetal heart rate is crucial to ensure the progress of labor and fetal well-being. This step allows the nurse to assess for any signs of fetal distress or labor progression. Administering pain relief medications (B) can be considered based on the woman's pain level, but it is not the immediate priority. Preparing for delivery (A) is premature at this stage. Performing a vaginal examination (D) may not be necessary unless there are concerns about fetal descent or progress of labor.
The nurse is caring for a pregnant patient who is 38 weeks gestation and reports feeling pelvic pressure and mild cramping. What should the nurse do first?
- A. Monitor the fetal heart rate and check for signs of labor.
- B. Instruct the patient to rest and monitor the symptoms.
- C. Assess the patient's blood pressure and urine for protein.
- D. Perform a pelvic exam to assess for cervical dilation.
Correct Answer: A
Rationale: The correct answer is A because monitoring the fetal heart rate and checking for signs of labor are essential in assessing the well-being of the fetus and determining if the patient is in active labor. This step helps the nurse identify any potential complications and take appropriate actions promptly.
Choice B is incorrect because simply instructing the patient to rest may not address the underlying cause of pelvic pressure and cramping.
Choice C is incorrect as assessing blood pressure and urine for protein is not the priority in this situation.
Choice D is incorrect because performing a pelvic exam should be done after monitoring fetal well-being and ruling out active labor.
