Nursing Elites

1. A teen with asthma asks the nurse why it is hard to breathe during an asthma attack. The nurse explains that exposure to a “trigger” results in which of these manifestations?

• A. Bronchodilation, muscle relaxation, and decreased mucus production
• B. Air trapping and hypo-inflation of the alveoli
• C. Air trapping and decreased blood flow to the upper airway
• D. Bronchoconstriction, airway inflammation, and excess mucus production

Correct answer: D

Rationale: The correct answer is D. Asthma triggers cause bronchoconstriction, airway inflammation, and increased mucus production, leading to difficulty breathing. This combination of manifestations results in narrowing of the airways, making it hard for the individual to breathe effectively. Choices A, B, and C are incorrect because during an asthma attack, bronchodilation, muscle relaxation, and decreased mucus production do not occur. Instead, the airways constrict, become inflamed, and produce excess mucus, contributing to the breathing difficulties experienced by individuals with asthma.

2. A breastfed infant is being seen in the clinic for a 6-month checkup. The mother tells the nurse that the infant recently began to suck her thumb. Which is the best nursing intervention?

• A. Reassure the mother that this is normal at this age
• B. Recommend the mother substitute a pacifier for her thumb
• C. Assess the infant for other signs of sensory deprivation
• D. Suggest the mother breastfeed the infant more often to satisfy her sucking needs

Correct answer: A

Rationale: Thumb sucking is a normal self-soothing behavior in infants and usually does not indicate a problem. Reassuring the mother that this is normal is the appropriate response.

3. Examination of the abdomen is performed correctly by the nurse in which order?

• A. Inspection, palpation, percussion, and auscultation
• B. Inspection, percussion, auscultation, and palpation
• C. Palpation, percussion, auscultation, and inspection
• D. Inspection, auscultation, percussion, and palpation

Correct answer: D

Rationale: The correct order for abdominal examination is inspection, auscult

4. What condition is the most common cause of acute renal failure in children?

• A. Pyelonephritis
• B. Tubular destruction
• C. Severe dehydration
• D. Upper tract obstruction

Correct answer: C

Rationale: Severe dehydration is the most common cause of acute renal failure in children, as it leads to prerenal azotemia, which can progress to renal failure if not corrected. Other causes like pyelonephritis and tubular destruction are less common and usually secondary to other conditions.

5. 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.
