Nursing Elites

1. A young child has coarctation of the aorta. What does the nurse expect to identify when taking the child’s vital signs?

• A. A weak radial pulse
• B. An irregular heartbeat
• C. A bounding femoral pulse
• D. An elevated radial blood pressure

Correct answer: A

Rationale: In coarctation of the aorta, there is narrowing of the aorta leading to decreased blood flow distal to the constriction. This results in a weak or delayed femoral pulse and a relatively weaker radial pulse compared to the femoral pulse. An irregular heartbeat (choice B) is not a typical finding in coarctation of the aorta. A bounding femoral pulse (choice C) would not be expected due to the decreased blood flow beyond the constriction. An elevated radial blood pressure (choice D) is not a common characteristic of coarctation of the aorta; instead, blood pressure may be higher in the upper extremities compared to the lower extremities due to the constriction.

2. A child has been admitted to the pediatric unit with a severe asthma attack. What type of acid-base imbalance should the nurse expect the child to develop?

• A. metabolic alkalosis caused by decreased acid metabolites production
• B. respiratory alkalosis caused by decreased respiratory rate and carbon dioxide retention
• C. respiratory acidosis caused by impaired respirations and increased carbonic acid formation
• D. metabolic acidosis caused by the kidneys' inability to compensate for increased carbonic acid production

Correct answer: C

Rationale: In a severe asthma attack, the child is likely to develop respiratory acidosis due to impaired respirations leading to the retention of carbon dioxide, which combines with water to form carbonic acid. This results in the pH imbalance characterized by an excess of carbonic acid. Choices A, B, and D are incorrect. Metabolic alkalosis (Choice A) is not typically associated with severe asthma attacks; respiratory alkalosis (Choice B) would involve a decrease, not an increase, in carbon dioxide levels; and metabolic acidosis (Choice D) is not the primary acid-base imbalance seen in severe asthma attacks.

3. After a discussion with the health care provider, the parents of an infant with patent ductus arteriosus (PDA) ask the nurse to explain once again what PDA is. How should the nurse respond?

• A. The diameter of the aorta is enlarged.
• B. The wall between the right and left ventricles is open.
• C. It is a narrowing of the entrance to the pulmonary artery.
• D. It is a connection between the pulmonary artery and the aorta.

Correct answer: D

Rationale: The correct answer is D: 'It is a connection between the pulmonary artery and the aorta.' Patent ductus arteriosus (PDA) is an abnormal connection between the pulmonary artery and the aorta, which normally closes after birth. Choices A, B, and C describe different cardiac conditions and do not accurately define PDA. Choice A is incorrect because PDA does not involve the diameter of the aorta being enlarged. Choice B is incorrect because PDA does not involve the wall between the right and left ventricles being open. Choice C is incorrect because PDA is not a narrowing of the entrance to the pulmonary artery.

4. The nurse is implementing care for a school-age child admitted to the pediatric intensive care unit with diabetic ketoacidosis (DKA). Which prescribed intervention should the nurse implement first?

• A. Begin 0.9% saline solution intravenously as prescribed
• B. Administer regular insulin intravenously as prescribed
• C. Place the child on a cardiac monitor
• D. Place the child on a pulse oximetry monitor

Correct answer: A

Rationale: The correct first intervention when managing a child with diabetic ketoacidosis is to begin intravenous saline solution to address dehydration and restore electrolyte balance. Rehydration is essential to improve perfusion and correct electrolyte imbalances. Administering insulin without addressing dehydration can potentially lead to further complications. Placing the child on a cardiac monitor or pulse oximetry monitor is important but not the initial priority in managing DKA.

5. Parents of a sick infant talk with a nurse about their baby. One parent says, “I am so upset; I didn’t realize our baby was ill.” What major indication of illness in an infant should the nurse explain to the parent?

• A. Grunting respirations
• B. Excessive perspiration
• C. Longer periods of sleep
• D. Crying immediately after feedings

Correct answer: C

Rationale: Longer periods of sleep than usual can be a sign of illness in infants. When an infant sleeps more than usual, it may indicate that the baby is conserving energy due to an underlying condition. Grunting respirations (choice A) can be a sign of respiratory distress, excessive perspiration (choice B) may indicate overheating or fever, and crying immediately after feedings (choice D) can be a sign of gastrointestinal discomfort, such as colic or reflux. However, in this scenario, the emphasis is on changes in sleep patterns as a potential indicator of illness.
