Nursing Elites

1. Before administering a tube feeding to a child, what should the practical nurse (PN) assess?

• A. Tube placement.
• B. Bowel sounds.
• C. Abdominal circumference.
• D. Tube patency.

Correct answer: A

Rationale: Assessing tube placement is critical before initiating a tube feeding to verify its correct positioning in the stomach. This assessment helps prevent potential complications such as aspiration if the tube is incorrectly placed in the respiratory tract. Checking bowel sounds, abdominal circumference, and tube patency are important assessments in the care of a child receiving tube feedings, but ensuring proper tube placement takes precedence to ensure safe and effective delivery of nutrition.

2. 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.

3. The healthcare provider is preparing to administer a scheduled dose of digoxin to a 4-year-old child with heart failure. The healthcare provider notes that the child’s heart rate is 70 beats per minute. What should the healthcare provider do next?

• A. Administer the medication as prescribed
• B. Hold the medication and notify the healthcare provider
• C. Recheck the heart rate in 30 minutes
• D. Administer half of the prescribed dose

Correct answer: B

Rationale: In pediatric patients, digoxin administration is guided by the heart rate. If the child's heart rate is below the established threshold, which is typically 90-100 beats per minute in a 4-year-old, the medication should be withheld, and the healthcare provider should be notified for further evaluation and instructions. Choice A is incorrect because administering the medication when the heart rate is low can lead to adverse effects. Rechecking the heart rate in 30 minutes (Choice C) may delay necessary intervention if the heart rate remains low. Administering half of the prescribed dose (Choice D) is not recommended without healthcare provider guidance.

4. What intervention should the nurse implement first for a male toddler brought to the emergency center approximately three hours after swallowing tablets from his grandmother’s bottle of digoxin (Lanoxin)?

• A. Administer activated charcoal orally
• B. Prepare gastric lavage
• C. Obtain a 12-lead electrocardiogram
• D. Give IV digoxin immune fab (Digibind)

Correct answer: D

Rationale: In cases of digoxin toxicity, IV digoxin immune fab (Digibind) is the antidote and should be administered first to counteract the effects of digoxin poisoning. This intervention is crucial in managing digoxin overdose and should be initiated promptly to improve patient outcomes. Activated charcoal and gastric lavage are not effective in treating digoxin poisoning and may not be beneficial at this stage. While obtaining an electrocardiogram is important to assess cardiac function, administering the antidote should take precedence to address the immediate life-threatening effects of digoxin toxicity.

5. What action should the nurse implement when the infusion of chemotherapy via an implanted medication port is complete for a 16-year-old with acute myelocytic leukemia at the outpatient oncology clinic?

• A. Administer Zofran
• B. Obtain blood samples for RBCs, WBCs, and platelets
• C. Flush mediport with saline and heparin solution
• D. Initiate an infusion of normal saline

Correct answer: C

Rationale: The correct action for the nurse to implement when the chemotherapy infusion is complete is to flush the mediport with saline and heparin solution. This process helps prevent clotting and ensures the patency of the port, which is essential for future medication administrations and blood draws. Administering Zofran (Choice A) is not necessary after completing the chemotherapy infusion. Obtaining blood samples (Choice B) for RBCs, WBCs, and platelets is important but not the immediate action after completing the infusion. Initiating an infusion of normal saline (Choice D) is not required unless there is a specific indication for it.
