Nursing Elites

1. At what age is binocularity, the ability to fixate on one visual field with both eyes simultaneously, typically achieved?

• A. 1 month
• B. 3 to 4 months
• C. 6 to 8 months
• D. 12 months

Correct answer: B

Rationale: Binocularity, the ability to fixate on one visual field with both eyes simultaneously, is typically achieved by the age of 3 to 4 months. Achieving binocularity at 1 month is too early for most infants as their visual system is still developing. Similarly, 6 to 8 months and 12 months are beyond the normal age range for achieving binocularity, and delayed achievement could indicate potential issues like strabismus, which may lead to visual impairment if not addressed.

2. Which congenital heart defect causes a "boot-shaped" heart on a chest x-ray?

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

Correct answer: A

Rationale: The correct answer is A: Tetralogy of Fallot. Tetralogy of Fallot, a congenital heart defect with four distinct abnormalities, often presents with a "boot-shaped" heart on chest x-ray due to right ventricular hypertrophy. This characteristic finding is due to the specific combination of defects in this condition. Coarctation of the aorta (choice B), Transposition of the great arteries (choice C), and Ventricular septal defect (choice D) do not typically result in a "boot-shaped" heart on a chest x-ray like Tetralogy of Fallot does.

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. An infant has been diagnosed with bladder obstruction. What do symptoms of this disorder include?

• A. Renal colic
• B. Strong urinary stream
• C. Urinary tract infections
• D. Post urination dribbling

Correct answer: D

Rationale: Post-urination dribbling is a symptom of bladder obstruction due to the incomplete emptying of the bladder. A strong urinary stream is typically absent in such cases. UTIs are common, but dribbling is more directly related to the obstruction.

5. Which statement regarding bottle mouth caries requires further teaching?

• A. Caries can be decreased by putting an infant to bed with a bottle of milk or sweetened juice
• B. Eliminating the bedtime bottle or substituting water is recommended
• C. Sugar pools within the oral cavity cause severe decay
• D. It is often seen in children between 18 months and 3 years

Correct answer: A

Rationale: The correct answer is A. Putting an infant to bed with a bottle of milk or sweetened juice increases the risk of bottle mouth caries rather than decreasing it. This statement requires further teaching as it provides incorrect information. Choice B is correct as eliminating the bedtime bottle or substituting water is recommended to prevent bottle mouth caries. Choice C is also correct as sugar pooling within the oral cavity can indeed cause severe decay. Choice D is correct as bottle mouth caries is often observed in children between 18 months and 3 years.
