A nurse is preparing to administer metronidazole 2 g PO to a client who has trichomoniasis. Available is metronidazole 250 mg tablets. How many tablets should the nurse administer?
- A. 8 tablets
- B. 4 Tablets
- C. 2 tablets
- D. 1 tablet
Correct Answer: A
Rationale: The correct answer is A: 8 tablets. To calculate the dose, divide the total dose by the dose per tablet. In this case, 2 g equals 2000 mg. Therefore, divide 2000 mg by 250 mg (dose per tablet), which equals 8 tablets. Each tablet contains 250 mg, so to reach the total dose of 2000 mg, the nurse needs to administer 8 tablets. Choice B (4 tablets) is incorrect because it would only provide 1000 mg, not the required 2000 mg. Choice C (2 tablets) would provide only 500 mg, not the required dose. Choice D (1 tablet) would provide only 250 mg, which is insufficient.

- C. Gestational age
- D. Vaginal examination
- E. Maternal blood pressure

B: Fetal heart rate - Abnormal fetal heart rate can indicate fetal distress.
D: Vaginal examination - Risk of infection or cervical changes need provider evaluation.

A nurse is assessing a client who gave birth vaginally 12 hr ago and palpates their uterus to the right above the umbilicus. Which of the following interventions should the nurse perform?
- A. Reassess the client in 2 hr.
- B. Administer simethicone.
- C. Assist the client to empty their bladder.
- D. Instruct the client to lie on their right side.
Correct Answer: C
Rationale: The correct answer is C: Assist the client to empty their bladder. Palpating the uterus above the umbilicus indicates uterine atony, a common cause of postpartum hemorrhage. A full bladder can displace the uterus further, exacerbating the risk of hemorrhage. Emptying the bladder will allow the uterus to contract properly and reduce the risk. Reassessing the client in 2 hours (A) delays immediate intervention. Administering simethicone (B) is for gas relief and not relevant in this situation. Instructing the client to lie on their right side (D) does not address the underlying issue of uterine atony.
A nurse is assessing four newborns. Which of the following findings should the nurse report to the provider?
- A. A newborn who is 26 hr old and has erythema toxicum on their face
- B. A newborn who is 32 hr old and has not passed a meconium stool
- C. A newborn who is 12 hr old and has pink-tinged urine
- D. A newborn who is 18 hr old and has an axillary temperature of 37.7°C (99.9°F)
Correct Answer: B
Rationale: The correct answer is B because failure to pass meconium within 24-48 hours can indicate a bowel obstruction or other serious issue that needs immediate attention. A: Erythema toxicum is a common benign rash in newborns. C: Pink-tinged urine can be due to uric acid crystals and is normal in newborns. D: An axillary temperature of 37.7°C (99.9°F) is within normal range for a newborn.
A nurse is teaching a client who is at 37 weeks of gestation and has a prescription for a nonstress test. Which of the following instructions should the nurse include?
- A. The test should take 10 to 15 minutes to complete.
- B. You will lay in a supine position throughout the test.
- C. You should not eat or drink for 2 hours before the test.
- D. You should press the handheld button when you feel your baby move.
Correct Answer: D
Rationale: Rationale: The correct answer is D because pressing the handheld button when feeling the baby move helps monitor fetal heart rate and movements during the test. This action allows healthcare providers to assess the baby's well-being. Choice A is incorrect as the test duration varies. Choice B is wrong as the client should lay on their left side, not supine, to prevent compression of the vena cava. Choice C is incorrect as eating and drinking are not restricted before the test.
A nurse is caring for a client who is 12 hr postpartum and has a fourth-degree laceration of the perineum. Which of the following actions should the nurse take?
- A. Apply a moist, warm compress to the perineum.
- B. Provide the client with a cool sitz bath.
- C. Administer methylergonovine 0.2 mg IM.
- D. Apply povidone-iodine to the client’s perineum after she voids.
Correct Answer: A
Rationale: Correct Answer: A. Apply a moist, warm compress to the perineum.
Rationale: Applying a moist, warm compress helps reduce pain, swelling, and discomfort in the perineal area postpartum. It promotes healing and provides comfort to the client with a fourth-degree laceration. This action also helps improve circulation to the area, aiding in the healing process.
Incorrect Choices:
B: Providing a cool sitz bath may provide relief for hemorrhoids or perineal discomfort but is not the best option for a fourth-degree laceration. Warm compresses are more suitable in this situation.
C: Administering methylergonovine is used to prevent or treat postpartum hemorrhage, not for perineal lacerations.
D: Applying povidone-iodine after voiding is not recommended as it can be irritating to the wound and delay healing.
