A nurse is teaching a newly licensed nurse about collecting a specimen for the universal newborn screening. Which of the following statements should the nurse include in the teaching?
- A. Obtain an informed consent prior to obtaining the specimen
- B. Collect at least milliliter of the urine for the test
- C. Ensure that the newborn has been receiving feedings for 24 hours prior to obtaining the specimen.
- D. Premature newborns may have false negative tests due to immature development of liver enzymes.
Correct Answer: C
Rationale: The correct answer is C: Ensure that the newborn has been receiving feedings for 24 hours prior to obtaining the specimen. This is important because certain metabolic disorders can only be detected if the baby has been feeding normally. Without proper feeding, the test results may not be accurate.
Choice A is incorrect because informed consent is not required for universal newborn screening; it is a routine procedure. Choice B is incorrect as urine is not typically used for the universal newborn screening. Choice D is incorrect because premature newborns may have false positive tests, not false negative tests, due to immature liver enzyme development.

Shortly after delivery, the nursery nurse gives the newborn an injection of phytonadione (Vitamin K). The infant's grandmother wants to know why the baby got 'a shot in his leg.' Which response by the nurse is most appropriate?
- A. Vitamin K promotes bone and muscle growth.
- B. Vitamin K helps the baby digest milk.
- C. Vitamin K helps stabilize the baby's blood sugar.
- D. Vitamin K is used to prevent bleeding.
Correct Answer: D
Rationale: The correct answer is D: Vitamin K is used to prevent bleeding. Shortly after birth, newborns have low levels of Vitamin K, which is essential for blood clotting. Administering phytonadione helps prevent a rare but serious condition called Vitamin K deficiency bleeding. Option A is incorrect as Vitamin K primarily supports blood clotting, not bone and muscle growth. Option B is incorrect as Vitamin K does not aid in digestion. Option C is incorrect as Vitamin K does not directly affect blood sugar stabilization.
A nurse is caring for a child with measles.
- A. "Provide diversional activities such as video games."'
- B. "Maintain isolation for 48 hr after the rash resolves."'
- C. "Keep the child warm with adequate undergarments and bedding."'
- D. "Administer vitamin A supplements as prescribed."'
Correct Answer: D
Rationale: The correct answer is D because administering vitamin A supplements is a standard treatment for measles to reduce complications and improve recovery. Vitamin A deficiency is common in children with measles, and supplementation can help boost the immune system and reduce the severity of the illness. Providing diversional activities (choice A) may be suitable but does not directly address the medical needs of the child. Maintaining isolation (choice B) is important but typically lasts until 4 days after rash onset, not just 48 hours after rash resolution. Keeping the child warm (choice C) is a general comfort measure and may not directly impact measles treatment.
Which physiological change takes place during the puerperium?
- A. The endometrium begins to undergo alterations necessary for menstruation.
- B. The placenta begins to separate from the uterine wall.
- C. The uterus returns to a pre-pregnant size and location.
- D. The uterus contracts at regular intervals with dilation of the cervix occurring.
Correct Answer: C
Rationale: During the puerperium, the correct physiological change is that the uterus returns to a pre-pregnant size and location (Choice C). This is because after childbirth, the uterus undergoes involution, gradually decreasing in size back to its pre-pregnant state. This process involves the shedding of excess tissue and contraction of uterine muscles. The endometrium (Choice A) does not undergo alterations for menstruation until after the puerperium, as menstruation typically resumes around 6-8 weeks postpartum. The placenta (Choice B) should have been expelled completely during the third stage of labor, so it does not separate during the puerperium. The uterus does contract, but it is not at regular intervals with cervical dilation (Choice D) during the puerperium.
A nurse is caring for a 4-year-old child diagnosed with leukemia who is admitted with myelosuppression.
- A. "Provide a diet high in carbohydrates."'
- B. "Monitor rectal temperature every 4 hr."'
- C. "Use lemon or glycerin swabs for oral care."'
- D. "Inspect the skin daily for lesions."'
Correct Answer: D
Rationale: The correct answer is D: "Inspect the skin daily for lesions." This is important because myelosuppression can lead to decreased platelets, increasing the risk of skin lesions and bleeding. Monitoring the skin daily can help detect any lesions early and prevent complications.
A: Providing a high-carbohydrate diet is not directly related to managing myelosuppression.
B: Monitoring rectal temperature is important but not directly related to skin lesion detection.
C: Using lemon or glycerin swabs for oral care is important for mucositis, not skin lesions.
A nurse is caring for an infant with a history of vomiting due to gastroenteritis. Which of the following nursing interventions is considered the priority?
- A. Place the infant in a side or semi-reclined position.
- B. Administer oral rehydration and electrolyte therapy.
- C. Administer antiemetic medications as prescribed.
- D. Maintain a high-carbohydrate intake to prevent ketosis.
Correct Answer: A
Rationale: Positioning the infant prevents aspiration, which is the highest priority.
