Nursing Elites

1. The healthcare provider is assessing an infant with pyloric stenosis. Which pathophysiological mechanism is the most likely consequence of this infant's clinical picture?

• A. Metabolic alkalosis.
• B. Respiratory acidosis.
• C. Metabolic acidosis.
• D. Respiratory alkalosis.

Correct answer: A

Rationale: Pyloric stenosis leads to obstruction at the outlet of the stomach, causing frequent vomiting and loss of stomach acids. This results in a loss of hydrochloric acid and hydrogen ions, leading to metabolic alkalosis due to an increase in serum bicarbonate levels. Therefore, the correct answer is metabolic alkalosis. Choice B, respiratory acidosis, is incorrect as it is not typically associated with pyloric stenosis. Choice C, metabolic acidosis, is incorrect because the loss of stomach acids in pyloric stenosis leads to metabolic alkalosis, not acidosis. Choice D, respiratory alkalosis, is also incorrect as it is not the usual consequence of pyloric stenosis.

2. A 7-year-old is admitted to the hospital with persistent vomiting, and a nasogastric tube attached to low intermittent suction is applied. Which finding is most important for the nurse to report to the healthcare provider?

• A. Gastric output of 100 mL in the last 8 hours.
• B. Shift intake of 640 mL IV fluids plus 30 mL PO ice chips.
• C. Serum potassium of 3.0 mEq/L.
• D. Serum pH of 7.45.

Correct answer: C

Rationale: A serum potassium level of 3.0 mEq/L is significantly low and indicates hypokalemia, which can lead to serious complications such as cardiac arrhythmias. Therefore, it is crucial for the nurse to report this finding promptly to the healthcare provider for immediate intervention. The other findings are not as critical in this situation. Gastric output of 100 mL in the last 8 hours may be expected in a patient with persistent vomiting. The shift intake of IV fluids and ice chips indicates fluid replacement, which is important but not as urgent as correcting electrolyte imbalances. A serum pH of 7.45 is within the normal range and does not indicate an immediate concern.

3. The practical nurse is caring for a child who was admitted for treatment of seizures. Which intervention should the nurse implement to help prevent injury from a seizure?

• A. Have a padded tongue depressor at the bedside.
• B. Keep the side rails padded and in an upright position.
• C. Place a padded helmet on the child’s head.
• D. Restrain the child during the seizure activity.

Correct answer: B

Rationale: The correct intervention to help prevent injury during a seizure is to keep the side rails padded and in an upright position. This measure helps to ensure the child's safety by preventing falls or accidental injuries. Using a padded tongue depressor or restraining the child can potentially cause harm and are not recommended. Placing a padded helmet is not a standard intervention for seizure safety in this scenario.

4. What is the priority action for a 2-year-old child with croup presenting with a barking cough and stridor?

• A. Administer a corticosteroid
• B. Obtain a throat culture
• C. Administer nebulized epinephrine
• D. Place the child in an upright position

Correct answer: C

Rationale: The priority action for a 2-year-old child with croup and stridor is to administer nebulized epinephrine. Nebulized epinephrine helps reduce airway swelling, alleviate symptoms, and improve breathing by causing vasoconstriction and reducing upper airway edema. Administering a corticosteroid may be done but is not the priority in this scenario. Obtaining a throat culture is not necessary for the immediate management of croup. Placing the child in an upright position can aid in breathing but is not the priority action when the child is presenting with stridor.

5. A 2-week-old female infant is hospitalized for the surgical repair of an umbilical hernia. After returning to the postoperative neonatal unit, her RR and HR have increased during the last hour. Which intervention should the nurse implement?

• A. Notify the healthcare provider of these findings
• B. Administer a PRN analgesic as prescribed
• C. Document the findings in the infant's medical record
• D. Comfort the infant by swaddling and gently rocking

Correct answer: A

Rationale: In a postoperative neonatal setting, an increase in respiratory rate (RR) and heart rate (HR) in an infant could indicate pain or distress. It is crucial for the nurse to notify the healthcare provider promptly to assess the infant's condition and provide appropriate interventions. Prompt communication with the healthcare provider ensures timely evaluation and management of the infant's discomfort or distress, promoting optimal postoperative recovery and comfort. Administering analgesics without healthcare provider assessment could mask underlying issues, documenting findings alone does not address the immediate need for intervention, and comforting may not resolve the underlying cause of increased RR and HR.
