Pediatric Nursing Practice Questions Questions
Question 1 of 5
Contact lenses are associated with
Correct Answer: D
Rationale: Giant papillary conjunctivitis is common in contact lens wearers due to chronic mechanical irritation and immune response.
Question 2 of 5
High pH, low carbon dioxide & normal bicarbonate best fit which of the following disorders?
Correct Answer: D
Rationale: Uncompensated respiratory alkalosis results from excessive ventilation, leading to low COâ‚‚ and a high pH. Normal bicarbonate indicates that metabolic compensation has not yet occurred.
Question 3 of 5
A child has just been unexpectedly admitted to the intensive care unit after abdominal surgery. The nursing staff has completed the admission process, and the child's condition is beginning to stabilize. When speaking with the parents, the nurses should expect which stressors to be evident? (Select all that apply.)
Correct Answer: A
Rationale: Unfamiliar environment: The child being in the intensive care unit is likely in an unfamiliar environment, which can be a significant stressor for both the child and the parents. The sights, sounds, and equipment in an ICU can be overwhelming and anxiety-provoking for families.
Question 4 of 5
Drug reactions to penicillins and cephalosporins are common in pediatrics. Risk factors for drug reactions include all the following EXCEPT
Correct Answer: B
Rationale: Increasing age (>20 years) is not a risk factor; in fact, drug reactions are more common in younger patients.
Question 5 of 5
When the nurse is reviewing a patient's daily laboratory test results, which of the ff. electrolyte imbalances should the nurse recognize as predisposing the patient to digoxin toxicity?
Correct Answer: A
Rationale: Hypokalemia, or low potassium levels, predisposes the patient to digoxin toxicity because potassium is essential for proper digoxin metabolism. Potassium competes with digoxin for binding sites on sodium-potassium ATPase pumps in the myocardial cells. When potassium levels are low, digoxin binding is increased, leading to an increased risk of digoxin toxicity. Monitoring and correcting hypokalemia are important in patients taking digoxin to reduce the risk of toxicity. Hyperkalemia, on the other hand, can increase the risk of digoxin toxicity by affecting electrophysiological properties of the heart, but hypokalemia is the most significant imbalance predisposing to digoxin toxicity.
