1. The client is admitted in active labor with a cervix that is 3 cm dilated, 50% effaced, and the presenting part at 0 station. An hour later, the client expresses the need to go to the bathroom. Which action should the nurse implement first?
- A. Palpate the client’s bladder.
- B. Check the pH of the vaginal fluid.
- C. Review the fetal heart rate pattern.
- D. Determine cervical dilation.
Correct answer: D
Rationale: The nurse should prioritize determining cervical dilation as it helps in assessing the progress of labor and ensures it is safe for the client to move. Changes in cervical dilation may indicate the advancement of labor, warranting appropriate interventions or restrictions on movement to prevent complications. While checking the client's bladder may be important to ensure it's not distended, determining cervical dilation takes precedence in this scenario. Checking the pH of the vaginal fluid is not relevant in this situation, and reviewing the fetal heart rate pattern, although important, is not the first action to take when the client expresses the need to go to the bathroom.
2. What action should the nurse take if an infant, who was born yesterday weighing 7.5 lbs (3,402 grams), weighs 7 lbs (3,175 grams) today?
- A. Inform and assure the mother that this is normal weight loss.
- B. Encourage the mother to increase the frequency of breastfeeding.
- C. After verifying the accuracy of weight, notify the healthcare provider.
- D. Monitor the stool and urine output of the neonate for the last 24 hours.
Correct answer: A
Rationale: The correct action for the nurse to take in this situation is to inform and assure the mother that this weight loss is normal. Newborns can lose up to 10% of their birth weight in the first few days after birth, which is attributed to fluid loss and adjustment to life outside the womb. This weight loss is typically regained within the first two weeks of life. It is crucial for the nurse to educate and provide reassurance to the mother about this common occurrence in newborns.
3. After a full-term vaginal delivery, a postpartum client's white blood cell count is 15,000/mm3. What action should the nurse take first?
- A. Check the differential, as the WBC count can be normal for this client.
- B. Assess the client's temperature, pulse, and respirations every 4 hours.
- C. Notify the healthcare provider, as this finding may indicate infection.
- D. Assess the client's perineal area for signs of a perineal hematoma.
Correct answer: A
Rationale: In postpartum clients, a white blood cell count of 15,000/mm3 can be within normal limits due to physiological changes that occur after childbirth. Checking the differential count would provide a more detailed analysis of the specific types of white blood cells present, helping to differentiate between normal postpartum changes and potential infection. This action allows the nurse to gather more information before escalating the situation to the healthcare provider or initiating other assessments. Assessing vital signs and the perineal area are important aspects of postpartum care but may not be the priority in this scenario where the white blood cell count can be influenced by normal physiological changes.
4. A client at 32 weeks gestation is hospitalized with severe pregnancy-induced hypertension (PIH), and magnesium sulfate is prescribed to control the symptoms. Which assessment finding indicates the therapeutic drug level has been achieved?
- A. 4+ reflexes
- B. Urinary output of 50 ml per hour
- C. A decrease in respiratory rate from 24 to 16
- D. A decreased body temperature
Correct answer: C
Rationale: A decrease in respiratory rate from 24 to 16 indicates that magnesium sulfate is effectively reducing central nervous system irritability, a desired therapeutic effect. This decrease in respiratory rate signifies that the drug has reached a therapeutic level to control symptoms of severe pregnancy-induced hypertension. Choices A, B, and D are incorrect because 4+ reflexes, urinary output, and body temperature are not direct indicators of achieving a therapeutic level of magnesium sulfate for controlling PIH symptoms.
5. A mother who is breastfeeding her baby receives instructions from the nurse. Which instruction is most effective to prevent nipple soreness?
- A. Wear a cotton bra.
- B. Increase nursing time gradually.
- C. Correctly place the infant on the breast.
- D. Manually express a small amount of milk before nursing.
Correct answer: C
Rationale: The most effective instruction to prevent nipple soreness when breastfeeding is to correctly place the infant on the breast. Proper latch-on techniques ensure that the baby is properly positioned, reducing the risk of nipple soreness. When the baby is positioned correctly, they can nurse effectively without causing discomfort to the mother.
