Nursing Elites

1. A child is hospitalized in acute renal failure and has a serum potassium greater than 7 mEq/L. What temporary measures that will produce a rapid but transient effect to reduce the potassium should the nurse expect to be prescribed? (Select all that apply.)

• A. Dialysis
• B. All below
• C. Sodium bicarbonate
• D. Glucose 50% and insulin

Correct answer: A

Rationale: Calcium gluconate, sodium bicarbonate, and glucose with insulin are used as temporary measures to rapidly reduce serum potassium levels. They help shift potassium into cells and stabilize the heart but do not remove potassium from the body like dialysis does.

2. The nurse is caring for a 1-month-old infant diagnosed with Hirschsprung’s disease. Which treatment measure should be included in the plan of care?

• A. Barium Enema
• B. Surgical removal of the affected section of bowel
• C. High-fiber diet
• D. Permanent colostomy

Correct answer: B

Rationale: The correct answer is B: Surgical removal of the affected section of bowel. Hirschsprung's disease is a congenital condition where a portion of the large intestine lacks nerve cells, leading to difficulties in passing stool. The definitive treatment for this condition is the surgical removal of the affected section of the bowel. Barium enema (Choice A) may be used for diagnosis but is not a treatment. A high-fiber diet (Choice C) is not effective in managing Hirschsprung's disease. A permanent colostomy (Choice D) is not the initial treatment for this condition in infants.

3. After surgery yesterday for gastroesophageal reflux, the nurse finds that the infant has somehow removed the nasogastric (NG) tube. What nursing action is most appropriate to perform at this time?

• A. Notify the healthcare provider.
• B. Insert a new NG tube for feedings.
• C. Replace the NG tube to maintain gastric decompression.
• D. Leave the NG tube out as it may have been in long enough.

Correct answer: A

Rationale: The most appropriate action for the nurse to take in this situation is to notify the healthcare provider immediately. This is important as the removal of the NG tube can disrupt postoperative care, especially in terms of maintaining gastric decompression. Inserting a new NG tube without practitioner direction can be unsafe and is not within the nurse's scope of practice. Similarly, replacing the NG tube or leaving it out should be decided by the healthcare provider to ensure the infant's safety and appropriate postoperative care.

4. According to Piaget, which principle supports a nine-year-old child's understanding that an arm will look the same when the IV is removed?

• A. The principle of conservation
• B. The principle of transductive reasoning
• C. The principle of identity
• D. The principle of reflex abilities

Correct answer: A

Rationale: The correct answer is A, the principle of conservation. Piaget's principle of conservation relates to a child's ability to understand that certain properties of objects remain unchanged despite modifications in their appearance. In this case, the child's understanding that an arm will look the same after the IV is removed demonstrates conservation of appearance. Choice B, transductive reasoning, involves making faulty generalizations based on specific instances and does not apply in this context. Choice C, the principle of identity, pertains to recognizing objects as the same even if they undergo transformations, which is not directly relevant to the scenario. Choice D, reflex abilities, refers to automatic responses to stimuli and is unrelated to the child's understanding of the arm's appearance post-IV removal.

5. Which pediatric disorder is associated with a 'boot-shaped' heart on a chest x-ray?

• A. Tetralogy of Fallot
• B. Transposition of the great arteries
• C. Coarctation of the aorta
• D. Ventricular septal defect

Correct answer: A

Rationale: The correct answer is A: Tetralogy of Fallot. Tetralogy of Fallot is often associated with a 'boot-shaped' heart appearance on a chest x-ray due to the characteristic heart anatomy in this condition. This appearance is caused by the combination of pulmonary stenosis, overriding aorta, ventricular septal defect, and right ventricular hypertrophy. Choice B, Transposition of the great arteries, is incorrect because it presents with a 'egg-on-a-string' appearance on x-ray due to the abnormal position of the aorta and pulmonary artery. Choice C, Coarctation of the aorta, typically presents with rib notching on x-ray. Choice D, Ventricular septal defect, does not produce the 'boot-shaped' heart appearance seen in Tetralogy of Fallot.
