Question 1 of 5
What is the recommended method of administering vitamin K to a newborn?
Correct Answer: A
Rationale: The correct answer is A: Intramuscular injection. Administering vitamin K via intramuscular injection ensures rapid absorption and immediate availability in newborns who are at risk for vitamin K deficiency bleeding. Oral administration may be less effective due to variability in absorption.
Topical application is not recommended for newborns. Subcutaneous injection may not provide as consistent absorption as intramuscular route. Overall, intramuscular injection is the most reliable and recommended method for vitamin K administration to newborns.
Question 2 of 5
Which stage of labor is characterized by the birth of the baby?
Correct Answer: B
Rationale: The correct answer is B: Second stage. This stage of labor is characterized by the birth of the baby. During the second stage, the cervix is fully dilated and the baby is pushed out through the birth canal. The first stage involves the onset of labor until full cervical dilation. The third stage is the delivery of the placenta. The fourth stage is the immediate postpartum period.
Choices E, F, and G are not relevant to the stages of labor. In summary, the second stage is specifically focused on the birth of the baby, making it the correct choice.
Question 3 of 5
A nurse is preparing to administer oxytocin to a client who is postpartum. Which of the following findings is an indication for the administration of the medication? (Select all that apply.)
Correct Answer: A,C
Rationale: Oxytocin is administered postpartum to manage uterine atony (flaccid uterus) and control excessive bleeding, which are common indications for its use.
Question 4 of 5
A nurse is assessing a newborn who was born at 26 weeks of gestation using the New Ballard Score. Which of the following findings should the nurse expect?
Correct Answer: A
Rationale: The correct answer is A: Minimal arm recoil. In premature newborns, particularly those born at 26 weeks of gestation, their muscle tone is typically low, leading to minimal arm recoil. This is a key characteristic assessed in the New Ballard Score to determine gestational age accurately. The other choices are incorrect because: B: A popliteal angle of 90° is more indicative of term infants; C: Creases over the entire foot sole are also seen in term infants; D: Raised areolas with 3 to 4 mm buds are features of newborns closer to term. Thus, A is the most appropriate finding for a newborn born at 26 weeks of gestation based on the New Ballard Score.
Question 5 of 5
What is the function of the cervix during pregnancy?
Correct Answer: A
Rationale: The correct answer is A:
To secrete mucus that prevents infection. The cervix acts as a barrier to protect the fetus from potential infections entering the uterus. The mucus produced by the cervix forms a plug that blocks the entry of harmful bacteria, reducing the risk of infection reaching the developing fetus.
Choices B, C, and D are incorrect because the cervix primarily functions to provide a protective barrier against infections during pregnancy, rather than solely protecting the fetus from trauma, regulating fetal temperature, or encompassing all functions mentioned in the other options.
