Nursing Elites

1. The student nurse has performed a gestational age assessment of an infant and finds the infant to be at 32 weeks. On which set of characteristics is the nurse basing this assessment?

• A. Lanugo mostly gone, little vernix remaining on the body
• B. Prominent clitoris, enlarging labia minora, patent anus
• C. Full areola, 5 to 10 mm nipple bud, pinkish-brown areola
• D. Skin opaque, cracking at wrists and ankles, no visible vessels

Correct answer: B

Rationale: The correct answer is B. At 30 to 32 weeks' gestation, the clitoris is prominent, and the labia minora are enlarging. The labia majora are small and widely separated. As gestational age increases, the labia majora increase in size. At 36 to 40 weeks, they almost cover the clitoris. At 40 weeks and beyond, the labia majora cover the labia minora and clitoris. Choices A, C, and D do not align with the characteristic features seen at 32 weeks of gestation, making them incorrect.

2. Which of the following clinical signs would MOST suggest acute respiratory distress in a 2-month-old infant?

• A. Heart rate of 130 beats/min
• B. Respiratory rate of 30 breaths/min
• C. Abdominal breathing
• D. Grunting respirations

Correct answer: D

Rationale: Grunting respirations are a key clinical sign of acute respiratory distress in infants. Grunting is a protective mechanism where the infant exhales against a partially closed glottis to increase functional residual capacity and oxygenation. This is often seen in conditions such as respiratory distress syndrome, pneumonia, or other causes of respiratory compromise in infants. Monitoring respiratory patterns like grunting is crucial for early recognition and intervention in infants with respiratory distress. Choices A, B, and C are less specific to acute respiratory distress in infants. While an elevated heart rate and respiratory rate can be present in respiratory distress, grunting respirations are a more direct indicator of significant respiratory compromise in infants.

3. Which of the following is NOT a function of hormones?

• A. Producing new offspring
• B. Promoting growth and beauty
• C. Maintaining body temperature
• D. Fighting infections

Correct answer: A

Rationale: Hormones play various roles in the body, such as promoting growth and beauty, maintaining body temperature, and fighting infections. However, producing new offspring is not a direct function of hormones. Reproduction is primarily regulated by other factors like the reproductive system. Choice B is incorrect because hormones can indeed influence growth but not specifically 'beauty.' Choice C is incorrect as hormones can help regulate body temperature indirectly. Choice D is incorrect as hormones like cytokines can be involved in the body's immune response to fight infections.

4. Your assessment of a 5-year-old child reveals that he is unresponsive with a respiratory rate of 8 breaths/min and a heart rate of 50 beats/min. Treatment for this child should include:

• A. high-flow oxygen via non-rebreathing mask and rapid transport.
• B. assisted ventilation with a bag-mask device and rapid transport.
• C. positive-pressure ventilation, chest compressions, and rapid transport.
• D. back slaps and chest thrusts while attempting artificial ventilations.

Correct answer: C

Rationale: In a 5-year-old child who is unresponsive with severe bradycardia and bradypnea, the priority is to provide positive-pressure ventilation to support breathing and perform chest compressions to support circulation. This child is in cardiac arrest, and the recommended treatment according to pediatric basic life support guidelines involves a combination of positive-pressure ventilation and chest compressions to maintain oxygenation and circulation. Rapid transport to a medical facility for further advanced care is crucial in this critical situation. Choices A, B, and D are incorrect because high-flow oxygen via non-rebreathing mask, assisted ventilation with a bag-mask device, and back slaps with chest thrusts are not sufficient in a cardiac arrest situation where the child requires immediate positive-pressure ventilation and chest compressions to maintain oxygenation and circulation.

5. How will a ventricular septal defect affect blood flow?

• A. Blood will shunt left to right, causing increased pulmonary flow and no cyanosis.
• B. Blood will shunt right to left, causing decreased pulmonary flow and cyanosis.
• C. No shunting occurs due to high pressure in the left ventricle.
• D. Increased pressure in the left atrium hinders the circulation of oxygenated blood in the circulating volume.

Correct answer: A

Rationale: A ventricular septal defect allows blood to shunt left to right, leading to increased pulmonary flow. This results in oxygenated blood mixing with deoxygenated blood, causing no cyanosis as the mixed blood is still oxygenated. The shunting from left to right overloads the pulmonary circulation, leading to increased pulmonary flow. Choice B is incorrect because blood does not shunt right to left in a ventricular septal defect. Choice C is incorrect as shunting does occur due to the pressure differences between the ventricles. Choice D is incorrect because the defect affects the ventricles, not the atrium, and does not hinder the circulation of oxygenated blood in the circulating volume.
