Nursing Elites

1. An infant with a congenital heart defect is being given gavage feedings. The parents ask the nurse why this is necessary. How should the nurse respond?

• A. It limits the chance of vomiting.
• B. It allows the feeding to be administered rapidly.
• C. The energy that would have been expended on sucking is conserved.
• D. The quantity of nutritional liquid can be regulated better than with a bottle.

Correct answer: C

Rationale: The correct answer is C: 'The energy that would have been expended on sucking is conserved.' Gavage feedings are necessary for infants with congenital heart defects as they help conserve the infant’s energy by eliminating the need for sucking, which can be taxing for infants with cardiac issues. Choice A is incorrect because gavage feedings are not primarily used to limit vomiting. Choice B is incorrect as the speed of administration is not the main reason for gavage feedings in this case. Choice D is incorrect because the regulation of the quantity of nutritional liquid is not the primary rationale for gavage feedings in infants with congenital heart defects.

2. A 3-year-old child with a history of frequent respiratory infections is being evaluated for cystic fibrosis. What diagnostic test should the nurse anticipate will be ordered?

• A. Chest X-ray
• B. Sweat chloride test
• C. Pulmonary function test
• D. Sputum culture

Correct answer: B

Rationale: The sweat chloride test is the gold standard diagnostic test for cystic fibrosis as it measures the concentration of chloride in sweat. In cystic fibrosis, there is an abnormal transport of chloride across epithelial membranes, leading to elevated sweat chloride levels. A chest X-ray may show characteristic changes in the lungs associated with cystic fibrosis, but it is not a definitive diagnostic test. Pulmonary function tests assess lung function but do not specifically diagnose cystic fibrosis. Sputum culture may identify respiratory infections but does not confirm the diagnosis of cystic fibrosis.

3. A 1-year-old child has a congenital cardiac malformation that causes right-to-left shunting of blood through the heart. What clinical finding should the nurse expect?

• A. Proteinuria
• B. Peripheral edema
• C. Elevated hematocrit
• D. Absence of pedal pulses

Correct answer: C

Rationale: In a child with a congenital cardiac malformation causing right-to-left shunting of blood, the nurse should expect an elevated hematocrit. This occurs because the body compensates for decreased oxygenation by producing more red blood cells. Proteinuria (Choice A) is not a typical clinical finding related to right-to-left shunting. Peripheral edema (Choice B) is more commonly associated with conditions causing volume overload, such as left-sided heart failure. Absence of pedal pulses (Choice D) is not directly related to right-to-left shunting but may be seen in conditions affecting peripheral circulation.

4. A nurse is planning an initial home care visit to a mother who gave birth to a high-risk infant. For what time of day should the nurse schedule the visit to be most productive?

• A. When the husband is out of the home.
• B. At a time when the mother is feeding the infant.
• C. At a time that is convenient for the family.
• D. When the nurse can spend time with the family.

Correct answer: C

Rationale: Scheduling the visit at a time that is convenient for the family is crucial for ensuring the family's receptiveness and availability, making the visit more productive. Choosing a time when the mother is feeding the infant (choice B) may not necessarily align with the family's overall convenience and may disrupt the feeding routine. Similarly, scheduling the visit when the husband is out of the home (choice A) might not be optimal as it may exclude an important family member and potentially impact the support system. While spending time with the family (choice D) is important, the primary focus should be on accommodating the family's schedule to maximize the effectiveness of the visit.

5. The nurse is admitting a newborn with hypospadias to the nursery. The nurse expects which finding in this newborn?

• A. Absence of a urethral opening is noted
• B. Penis appears shorter than usual for age
• C. The urethral opening is along the dorsal surface of the penis
• D. The urethral opening is along the ventral surface of the penis

Correct answer: D

Rationale: In hypospadias, the urethral opening is located along the ventral surface of the penis. This congenital condition results in the urethral meatus opening on the underside of the penis, rather than at the tip. Choice A is incorrect as there is typically a urethral opening present, though in an abnormal location. Choice B is not a characteristic feature of hypospadias. Choice C is incorrect as the urethral opening in hypospadias is not along the dorsal surface but rather along the ventral surface of the penis.
