Nursing Elites

1. What is the most appropriate nursing action when intermittently gavage feeding a preterm infant?

• A. Allow formula to flow by gravity
• B. Avoid allowing the infant to suck on the tube
• C. Insert the tube through the nares instead of the mouth
• D. Apply gentle pressure to the syringe to deliver the formula

Correct answer: A

Rationale: The correct action when intermittently gavage feeding a preterm infant is to allow the formula to flow by gravity. This method helps prevent overfeeding and aspiration, which can occur if the formula is delivered too quickly under pressure. Choice B is incorrect as sucking on the tube can cause complications. Choice C is incorrect as the tube is typically inserted through the mouth. Choice D is incorrect as steady pressure can lead to rapid delivery of the formula, increasing the risk of complications.

2. 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.

3. When taking a child’s blood pressure, what percentage of the upper arm should the nurse ensure the cuff bladder width covers?

• A. 20%
• B. 40%
• C. 60%
• D. 80%

Correct answer: B

Rationale: When taking a child's blood pressure, the nurse should select a cuff with a bladder width that covers 40% of the arm circumference at the midpoint of the upper arm. This ensures accurate readings. Choosing a cuff that covers less or more than 40% can lead to incorrect blood pressure measurements. Therefore, options A, C, and D are incorrect.

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. The parent of a 2-week-old infant asks the nurse if fluoride supplements are necessary because the infant is exclusively breastfed. What is the nurse's best response?

• A. The infant needs to begin taking them now.
• B. Supplements are not needed if you drink fluoridated water.
• C. The infant may need to begin taking them at age 6 months.
• D. The infant can have infant cereal mixed with fluoridated water instead of supplements.

Correct answer: C

Rationale: Breastfed infants may need fluoride supplements starting at 6 months if they are not receiving fluoride from other sources, such as drinking water.
