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. At which age can most infants sit steadily unsupported?

• A. 4 months
• B. 6 months
• C. 8 months
• D. 12 months

Correct answer: C

Rationale: Most infants can sit steadily without support by 8 months, indicating advanced gross motor skill development.

3. Which distraction technique should be used for an adolescent child during a painful procedure?

• A. Blowing bubbles
• B. Guided imagery
• C. EMLA cream
• D. Sucrose solution

Correct answer: B

Rationale: The correct answer is B: Guided imagery. Guided imagery is an effective distraction technique for adolescents as it helps them focus on positive mental images instead of the pain. This technique can be a powerful tool in managing pain and anxiety during procedures. Blowing bubbles (choice A) may be more suitable for younger children as it can engage them visually and help distract them. EMLA cream (choice C) is a topical anesthetic and not a distraction technique. Sucrose solution (choice D) is used for pain relief in infants, not typically for adolescents undergoing painful procedures.

4. The nurse is preparing to administer a measles, mumps, rubella, and varicella (MMRV) vaccine. Which is a contraindication associated with administering this vaccine?

• A. The child has recently been exposed to an infectious disease
• B. The child has symptoms of a cold but no fever
• C. The child is having intermittent episodes of diarrhea
• D. The child has a disorder that causes a deficient immune system

Correct answer: D

Rationale: A compromised immune system is a contraindication for the MMRV vaccine because it is a live attenuated vaccine and could potentially cause an infection in an immunocompromised child.

5. What disease should be suspected in a 3-day-old infant presenting with abdominal distention, vomiting, and failure to pass meconium?

• A. Pyloric stenosis
• B. Intussusception
• C. Hirschsprung disease
• D. Celiac disease

Correct answer: C

Rationale: Hirschsprung disease should be suspected in a newborn with abdominal distention, vomiting, and failure to pass meconium. This condition arises from a congenital absence of nerve cells in a portion of the colon, leading to severe constipation and intestinal obstruction. Pyloric stenosis typically presents with non-bilious projectile vomiting in the first few weeks of life. Intussusception classically manifests with sudden onset of colicky abdominal pain and currant jelly stools. Celiac disease may present with chronic diarrhea, failure to thrive, and abdominal distention but is less likely in this scenario.
