Nursing Elites

1. The nurse is using the New Ballard Score to assess the gestational age of a newborn delivered 4 hours ago. The infant's gestational age is 33 weeks based on early ultrasound and last menstrual period. The nurse expects the infant to exhibit which of the following?

• A. Full sole creases, nails extending beyond the fingertips, scarf sign showing the elbow beyond the midline
• B. Testes located in the upper scrotum, rugae covering the scrotum, vernix covering the entire body
• C. Ear cartilage folded over, lanugo present over much of the body, slow recoil time
• D. 1 cm breast bud, peeling skin and veins not visible, rapid recoil of legs and arms to extension

Correct answer: C

Rationale: The correct answer is C. Ear cartilage folded over, lanugo present over much of the body, and slow recoil time are all characteristics of a preterm infant. A is incorrect because full sole creases, nails extending beyond the fingertips, and scarf sign showing the elbow beyond the midline are features of a term infant. B is incorrect as testes located in the upper scrotum, rugae covering the scrotum, and vernix covering the entire body are also indicative of a term infant. D is incorrect because a 1 cm breast bud, peeling skin and veins not visible, and rapid recoil of legs and arms to extension are characteristics seen in a more mature infant, not a preterm newborn.

2. What is the main function of the uterus?

• A. Dilate and expel the baby from the cervix.
• B. House the fetus as it grows for 40 weeks.
• C. Provide a cushion and protect the fetus from infection.
• D. Provide oxygen and other nutrients to the fetus.

Correct answer: B

Rationale: The main function of the uterus is to house and nurture the growing fetus for approximately 40 weeks during pregnancy. It provides the necessary environment for the fetus to develop and grow until it is ready for birth. Choice A is incorrect as the cervix, not the uterus, dilates during labor to allow the baby to pass through. Choice C is incorrect as while the uterus does provide a protective environment, its primary function is not to act as a cushion. Choice D is incorrect as the placenta, not the uterus, is responsible for providing oxygen and nutrients to the fetus.

3. Which of the following is not an infectious cause of diarrhea?

• A. Allergy
• B. Bacteria
• C. Parasite
• D. Virus

Correct answer: A

Rationale: The correct answer is A: Allergy. Allergy is not an infectious cause of diarrhea. Diarrhea caused by bacteria, parasites, and viruses is due to infection, while an allergy triggers an immune response that can lead to diarrhea but is not caused by an infectious agent. Choices B, C, and D are incorrect because bacteria, parasites, and viruses are known infectious causes of diarrhea, resulting from infections by these microorganisms.

4. A 3-year-old child has been admitted to your pediatric ward. The doctor gave a provisional diagnosis of respiratory tract infection. After careful assessment and history, a final diagnosis of lower respiratory infection was made. Which of the following signs will confirm the diagnosis?

• A. Cough
• B. Fever
• C. Inability to lie supine
• D. Inability to eat

Correct answer: C

Rationale: Inability to lie supine is a characteristic sign of lower respiratory infection. This positioning preference is often seen in patients with lower respiratory infections due to discomfort or difficulty breathing when lying flat on their back. While cough and fever are common symptoms associated with respiratory infections, they are not specific to lower respiratory infections. Inability to eat may indicate general illness or discomfort but is not a specific indicator of lower respiratory infection.

5. A 4-year-old boy ingested an unknown quantity of drain cleaner. He is alert, has a patent airway, and has adequate breathing. You should:

• A. administer 1 g/kg of activated charcoal.
• B. give 15 mL of ipecac and contact medical control.
• C. contact poison control and give him oxygen.
• D. give oxygen and perform a head-to-toe exam.

Correct answer: C

Rationale: When a child ingests a harmful substance like drain cleaner and remains alert with a patent airway and adequate breathing, the initial steps involve contacting poison control to guide further management. In this scenario, providing oxygen to support respiratory function is essential until definitive care is established. Activated charcoal and ipecac are not recommended in the management of ingested caustic substances like drain cleaner. Performing a head-to-toe exam can wait until the child's immediate respiratory needs are addressed and the poison control center has provided guidance on further management.
