Nursing Elites

1. 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.

2. A new mother asks the nurse when she should begin to breastfeed her newborn. The nurse's best response is:

• A. Within the first half-hour after birth
• B. After the newborn's first bath
• C. When the newborn begins to cry
• D. After administering vitamin K

Correct answer: A

Rationale: Initiating breastfeeding within the first half-hour after birth is crucial for successful breastfeeding and bonding, as recommended by the World Health Organization. This early initiation helps establish breastfeeding and supports the newborn's health by providing colostrum, the nutrient-rich first milk. Choice B, 'After the newborn's first bath,' is incorrect because initiating breastfeeding should not be delayed after birth. Choice C, 'When the newborn begins to cry,' is incorrect as it does not promote timely initiation of breastfeeding. Choice D, 'After administering vitamin K,' is incorrect because breastfeeding initiation should not be delayed for this procedure.

3. What characteristic indicates that a mass on a newborn's head is a cephalohematoma?

• A. The mass appears on the second day after birth.
• B. The mass grows larger when the newborn cries.
• C. The head appears asymmetrical.
• D. The mass is located on only one side of the head.

Correct answer: A

Rationale: A cephalohematoma typically appears between the first and second days after birth, making choice A the correct answer. It results from blood vessel rupture between a cranial bone and the periosteal membrane. Choices B, C, and D are incorrect because the growth of the mass when the newborn cries, asymmetrical head appearance, or the mass being located on only one side of the head are not specific indicators of a cephalohematoma.

4. Your assessment of a newborn reveals cyanosis to the chest and face and a heart rate of 90 beats/min. What should you do first?

• A. Dry the infant briskly.
• B. Suction the mouth.
• C. Begin artificial ventilations.
• D. Begin chest compressions.

Correct answer: C

Rationale: In a newborn with cyanosis to the chest and face and a heart rate of 90 beats/min, the priority action is to begin artificial ventilations. A heart rate below 100 beats/min with cyanosis indicates a need for immediate respiratory support to improve oxygenation. Drying the infant briskly or suctioning the mouth may be necessary later but are not the initial priority. Chest compressions are not indicated as the heart rate is above 60 beats/min.

5. Which of the following statements regarding SIDS is correct?

• A. SIDS can occur in premature infants.
• B. It is most commonly a result of child abuse.
• C. Death usually occurs during sleep.
• D. SIDS can be prevented by placing the baby on its back to sleep.

Correct answer: C

Rationale: The correct statement regarding SIDS is that death usually occurs during sleep. Sudden Infant Death Syndrome (SIDS) is the unexpected death of a seemingly healthy infant, typically occurring during sleep. The exact cause of SIDS is not fully understood. While placing the baby on its back to sleep is a recommended preventive measure to reduce the risk of SIDS, it cannot guarantee prevention. Choice A is incorrect as SIDS is not limited to premature infants. Choice B is incorrect as SIDS is not primarily caused by child abuse.
