Nursing Elites

1. 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.

2. The nurse is preparing to give acetaminophen (Tylenol) to a child who has a fever. What nursing action is appropriate?

• A. Retake the temperature in 15 minutes after giving the Tylenol.
• B. Place a warm blanket on the child so chilling does not occur.
• C. Check to be sure the Tylenol dose does not exceed 15 mg/kg.
• D. Use cold compresses instead of Tylenol to control the fever.

Correct answer: C

Rationale: Ensuring the dose does not exceed 15 mg/kg is critical to avoid overdose and potential liver damage. Retaking the temperature immediately or using cold compresses is not necessary, and placing a warm blanket could exacerbate the fever.

3. The nurse is preparing to admit a 10-year-old child with appendicitis. What clinical manifestations should the nurse expect to observe?

• A. Fever
• B. Vomiting
• C. Tachycardia
• D. All of the above

Correct answer: D

Rationale: Correct! Typical signs of appendicitis include fever, vomiting, and tachycardia due to infection and inflammation. These clinical manifestations are commonly observed in patients with appendicitis. Hyperactive bowel sounds are not typically associated with appendicitis, so they are not expected findings in this situation. Therefore, the correct answer is 'All of the above.'

4. What is the first step in managing a child with anaphylaxis?

• A. Administer antihistamines
• B. Establish IV access
• C. Administer epinephrine
• D. Monitor vital signs

Correct answer: C

Rationale: The correct answer is to administer epinephrine. Administering epinephrine is the crucial first step in managing anaphylaxis as it helps reverse the severe allergic reaction by constricting blood vessels and relaxing airway muscles, preventing a life-threatening situation. Antihistamines (Choice A) are not the first-line treatment for anaphylaxis and should not delay the administration of epinephrine. Establishing IV access (Choice B) may be necessary but is not the initial step in managing anaphylaxis. Monitoring vital signs (Choice D) is important but should not take precedence over administering epinephrine in the acute management of anaphylaxis.

5. The charge nurse in the pediatric unit is teaching nursing students about pyloric stenosis. A student asks what causes pyloric stenosis. How should the nurse respond?

• A. One portion of the intestines invaginates or telescopes into another
• B. Hypertrophy of the circular pylorus muscle
• C. Relaxed cardiac sphincter
• D. Absent ganglion cells in the colon

Correct answer: B

Rationale: Pyloric stenosis is caused by the hypertrophy (thickening) of the circular muscle of the pylorus, leading to obstruction. Choice A is incorrect as it describes intussusception, not pyloric stenosis. Choice C is incorrect as a relaxed cardiac sphincter is related to gastroesophageal reflux. Choice D is incorrect as it describes Hirschsprung's disease, not pyloric stenosis.
