Nursing Elites

1. A 12-year-old child is injured in a bicycle accident. When considering the possibility of renal trauma, the nurse should consider what factor?

• A. Flank pain rarely occurs in children with renal injuries.
• B. Few nonpenetrating injuries cause renal trauma in children.
• C. Kidneys are immobile, well protected, and rarely injured in children.
• D. The amount of hematuria is not a reliable indicator of the seriousness of renal injury.

Correct answer: D

Rationale: The amount of hematuria is not a reliable indicator of the severity of renal trauma, as even minor injuries can cause significant bleeding, while severe injuries may result in little or no visible blood. Renal trauma should be evaluated through imaging and clinical assessment.

2. What pathologic process is believed to be responsible for the development of postinfectious glomerulonephritis?

• A. Infarction of renal vessels
• B. Immune complex formation and glomerular deposition
• C. Bacterial endotoxin deposition on and destruction of glomeruli
• D. Embolization of glomeruli by bacteria and fibrin from endocardial vegetation

Correct answer: B

Rationale: Postinfectious glomerulonephritis is typically caused by immune complex deposition in the glomeruli following a streptococcal infection. This immune response leads to inflammation and impaired kidney function.

3. Melena, the passage of black, tarry stools, suggests bleeding from which source?

• A. The perianal or rectal area
• B. The upper gastrointestinal (GI) tract
• C. The lower GI tract
• D. Hemorrhoids or anal fissures

Correct answer: B

Rationale: Melena indicates bleeding from the upper GI tract. The black, tarry appearance of the stool results from the partial digestion of blood as it passes through the intestines, typically originating from sources like the stomach or duodenum. Lower GI bleeding usually presents as bright red blood in the stool, originating from sources like the colon or rectum. Choices A, C, and D are incorrect because melena specifically points to upper GI bleeding rather than issues in the perianal/rectal area, lower GI tract, or hemorrhoids/anal fissures.

4. A mother delivers an infant at 30 weeks gestation. The mother asks the nurse for information on nutrition and if formula would be better since the baby is premature. What is the foundation for the response to the mother by the nurse?

• A. Human milk is preferred over other types of nutrition.
• B. Human milk lacks essential nutrients when the infant is preterm.
• C. Commercial infant formulas are preferred over other types of nutrition.
• D. Commercial infant formulas have not been designed to meet the nutritional needs of preterm infants.

Correct answer: A

Rationale: The correct answer is A. Human milk is the preferred food for infants, including preterm infants. It contains essential ingredients necessary for the infant's growth and development. The mother should pump her breasts to provide milk for the infant if the child is receiving enteral feedings. Once the infant can coordinate breathing, sucking, and swallowing, breastfeeding directly is encouraged. Studies have shown that preterm infants fed fortified human milk have better outcomes compared to those fed commercial infant formulas. Commercial infant formulas may not fully meet the unique nutritional needs of preterm infants, leading to potential longer hospital stays. Therefore, human milk is the best choice for feeding premature infants.

5. The nurse is caring for an infant who had surgical repair of a tracheoesophageal fistula 24 hours ago. Gastrostomy feedings have not been started. What do nursing actions related to the gastrostomy tube include?

• A. Keep the tube clamped.
• B. Suction the tube as needed.
• C. Leave the tube open to gravity drainage.
• D. Secure the tube with tape.

Correct answer: C

Rationale: Leaving the gastrostomy tube open to gravity drainage prevents the accumulation of air and fluids, reducing the risk of complications such as vomiting or aspiration in the immediate postoperative period. Keeping the tube clamped or suctioning it can lead to pressure buildup, increasing the risk of complications. Securing the tube with tape is important but not the primary action related to the gastrostomy tube in this case.
