ATI Maternal Newborn 2023 Questions
Extract:
A nurse is preparing an in-service program about preventing medication errors when transcribing a prescription. The nurse is using a dosage example of two tenths of a milligram.
Question 1 of 5
Which of the following examples should the nurse use to show appropriate transcription of this dosage?
Correct Answer: A
Rationale: The correct answer is A: 0.2 mg. This format is the most appropriate for dosage transcription as it clearly indicates the decimal point. B: 0.20 mg is redundant since the zero after the decimal does not add any value. C: 20 mg is incorrect as it represents a different dosage amount. D: 2 mg is also incorrect as it is not the same dosage as the one provided. The key is to accurately represent the dosage with the appropriate decimal place, making A the correct choice.
Extract:
A nurse has received an order to administer Morphine 5mg IV once immediately. The available concentration is 2.5 mg/mL.
Question 2 of 5
How many mL of morphine should the nurse prepare for administration?
Correct Answer: C
Rationale: The correct answer is C: 2 mL. Morphine is usually available in concentrations of 10 mg/mL. If the prescribed dose is 20 mg, the nurse should prepare 2 mL (20 mg ÷ 10 mg/mL = 2 mL).
Choices A, B, and D are incorrect because they do not match the calculated dose based on the concentration of morphine.
Extract:
A patient is in preterm labor at 30 weeks gestation. Her OB orders antenatal steroids. The order is for the nurse to administer betamethasone IM and to repeat the dose after 2 hours. Betamethasone is available as 4mg/mL in 10 mL vials.
Question 3 of 5
How many mL will the nurse draw up in the syringe for each dose?
Correct Answer: D
Rationale: Standard betamethasone dose for preterm labor is 12 mg. 12 mg ÷ 4 mg/mL = 3 mL per dose.
Extract:
A nurse is preparing to measure the fundal height of a client who is at 22 weeks of gestation.
Question 4 of 5
At which location should the nurse expect to palpate the fundus?
Correct Answer: D
Rationale: The correct answer is D, slightly above the umbilicus. This is the expected location to palpate the fundus immediately after childbirth. Fundal height corresponds with the number of weeks postpartum, so it should be around the level of the umbilicus within 12 hours postpartum and gradually decrease over the following days. Option A is too high for immediate postpartum, and option B is too low. Option C is incorrect as it suggests the fundus is below the umbilicus, which is not expected.
Extract:
The nurse caring for the pregnant patient understands that which hormone is essential for maintaining pregnancy?
Question 5 of 5
Which hormone is essential for maintaining pregnancy?
Correct Answer: D
Rationale: The correct answer is D: Progesterone. Progesterone is essential for maintaining pregnancy as it helps prepare the uterus for implantation and supports the growth of the placenta. It also inhibits contractions of the uterine muscles, preventing premature labor. Estrogen (
A) plays a role in preparing the uterus for pregnancy, but progesterone is crucial for maintaining it. Oxytocin (
B) stimulates uterine contractions during labor, not for maintaining pregnancy. Human chorionic gonadotropin (hCG) (
C) is produced during pregnancy but its main function is to support the corpus luteum in the early stages, not to maintain pregnancy.
