Nursing Elites

1. A nurse is reviewing laboratory results for a term newborn who is 24 hours old. Which of the following results require intervention by the nurse?

• A. WBC count 10,000/mm3
• B. Platelets 180,000/mm3
• C. Hemoglobin 20g/dL
• D. Glucose 20 mg/dL

Correct answer: D

Rationale: A glucose level of 20 mg/dL is critically low for a newborn and requires immediate intervention. Hypoglycemia in a newborn can lead to serious complications such as neurologic deficits. The normal range for glucose levels in a newborn is typically 40-60 mg/dL. Choices A, B, and C represent normal or acceptable values for a term newborn and do not require immediate intervention. A WBC count of 10,000/mm3, platelets of 180,000/mm3, and hemoglobin of 20g/dL are all within normal ranges for a term newborn and do not raise immediate concerns.

2. The _____ is the inner layer of the embryo from which the lungs and digestive system develop.

• A. neural tube
• B. mesoderm
• C. endoderm
• D. umbilical cord

Correct answer: C

Rationale: The endoderm is the correct answer. It is the innermost layer of the embryo that gives rise to organs such as the lungs, digestive system, liver, and pancreas. The neural tube (Choice A) forms the brain and spinal cord, not the lungs or digestive system. Mesoderm (Choice B) develops into structures like muscles, bones, and circulatory system, not the lungs or digestive system. The umbilical cord (Choice D) serves as a connection between the embryo and the placenta, providing nutrients and oxygen, but it is not the layer from which lungs and digestive system develop.

3. A newborn is 24 hours old, and a healthcare provider is caring for them. Which of the following laboratory findings should the healthcare provider report to the provider?

• A. Hgb 20 g/dL
• B. Bilirubin 2 mg/dL
• C. Platelets 200,000/mm3
• D. WBC count 32,000/mm3

Correct answer: D

Rationale: The correct answer is D: WBC count 32,000/mm3. A WBC count of 32,000/mm3 is significantly elevated in a newborn and could indicate an infection, which needs immediate attention and intervention. High white blood cell counts in newborns can be concerning as they may suggest an ongoing infection or other underlying issues that require prompt medical evaluation and treatment. Choices A, B, and C are within normal ranges for a newborn and would not typically warrant immediate reporting to the provider. Hgb levels of 20 g/dL (Choice A) are high for newborns, but this is not as concerning as a significantly elevated WBC count. Bilirubin levels of 2 mg/dL (Choice B) are within normal limits for a newborn and do not indicate immediate issues. Platelet count of 200,000/mm3 (Choice C) is also within the normal range for a newborn and would not require immediate reporting.

4. A newborn nursery protocol includes a prescription for ophthalmic erythromycin 5% ointment to both eyes upon a newborn's admission. What action should the nurse take to ensure adequate installation of the ointment?

• A. Instill a thin ribbon into each lower conjunctival sac
• B. Occlude the inner canthus after retracting the eyelids
• C. Mummy wrap the infant before instilling the ointment
• D. Stabilize the instilling hand on the neonate's head

Correct answer: A

Rationale: To ensure adequate installation of the ophthalmic erythromycin 5% ointment in a newborn, the nurse should instill a thin ribbon into each lower conjunctival sac. This method helps to ensure proper distribution and effectiveness of the medication to prevent neonatal conjunctivitis. Choices B, C, and D are incorrect. Occluding the inner canthus after retracting the eyelids, mummy wrapping the infant, or stabilizing the instilling hand on the neonate's head are not appropriate actions for ensuring the proper installation of the ointment.

5. A nurse on the labor and delivery unit is assessing four clients. Which of the following clients is a candidate for an induction of labor with misoprostol?

• A. A client who has active genital herpes
• B. A client who has gestational diabetes mellitus
• C. A client who has a previous uterine incision
• D. A client who has placenta previa

Correct answer: B

Rationale: Misoprostol can be used for induction in clients with gestational diabetes mellitus. Choice A, a client with active genital herpes, is not a candidate for misoprostol induction due to the risk of viral shedding and transmission. Choice C, a client with a previous uterine incision, may be at risk for uterine rupture with misoprostol use. Choice D, a client with placenta previa, is not an appropriate candidate for misoprostol induction due to the risk of increased bleeding associated with the condition.
