Nursing Elites

1. How is the diagnosis of Hirschsprung disease confirmed in a 1-month-old infant admitted to the pediatric unit?

• A. Colonoscopy
• B. Rectal biopsy
• C. Multiple saline enemas
• D. Fiberoptic nasoenteric tube

Correct answer: B

Rationale: Rectal biopsy is the definitive diagnostic procedure for Hirschsprung disease in infants. It confirms the absence of ganglion cells in the affected bowel segment, which is characteristic of Hirschsprung disease. Colonoscopy (Choice A) is not typically used for confirmation as it may not provide a definitive result. Multiple saline enemas (Choice C) are utilized in the treatment of meconium ileus, a complication of cystic fibrosis, and not in the diagnosis of Hirschsprung disease. Fiberoptic nasoenteric tube (Choice D) is not a diagnostic tool for Hirschsprung disease; it is commonly used for gastrointestinal decompression or feeding purposes but does not confirm the diagnosis.

2. A healthcare professional is assessing a child with suspected pertussis. What clinical manifestation is the healthcare professional likely to observe?

• A. Dry, hacking cough
• B. Inspiratory stridor
• C. Nasal congestion
• D. Severe coughing spells

Correct answer: D

Rationale: Severe coughing spells are a hallmark clinical manifestation of pertussis. Pertussis, also known as whooping cough, is characterized by paroxysms of rapid, consecutive coughs followed by a distinctive 'whoop' sound as the patient gasps for air. This intense coughing can lead to vomiting, exhaustion, and sometimes a characteristic 'whoop' sound. Inspiratory stridor (Choice B) is more commonly associated with croup, not pertussis. Nasal congestion (Choice C) is not a typical feature of pertussis. While a cough is present in pertussis, the specific type of cough described in Choice A (dry, hacking cough) is not the predominant feature observed in pertussis.

3. A group of students is reviewing information about the various types of insulin used to treat type 1 diabetes. The students demonstrate understanding of the information when they identify which of these insulins as having the longest duration.

• A. Lispro
• B. Regular
• C. NPH
• D. Glargine

Correct answer: D

Rationale: The correct answer is Glargine (Lantus) as it has the longest duration of action among the insulins listed, lasting 12 to 24 hours. Lispro (Humalog) and Regular (short-acting) insulins have shorter durations of action, typically lasting 3 to 6 hours. NPH (Neutral Protamine Hagedorn) insulin has an intermediate duration of action, lasting around 12 to 18 hours. Therefore, choices A, B, and C are incorrect in the context of insulin duration.

4. A child is being assessed by a nurse for suspected nephrotic syndrome. What clinical manifestation is the nurse likely to observe?

• A. Jaundice
• B. Edema
• C. Hypertension
• D. Polyuria

Correct answer: B

Rationale: Edema is a hallmark clinical manifestation of nephrotic syndrome. In nephrotic syndrome, there is increased permeability of the glomerular filtration barrier, leading to protein loss in the urine (proteinuria). The decrease in serum protein levels results in a reduced oncotic pressure, leading to fluid shifting from the intravascular space into the interstitial spaces, causing edema. Jaundice (choice A) is not typically associated with nephrotic syndrome. Hypertension (choice C) is more commonly seen in conditions like nephritic syndrome. Polyuria (choice D) is excessive urination and is not a prominent feature of nephrotic syndrome.

5. The school nurse is caring for a boy with hemophilia who fell on his arm during recess. What supportive measures should the nurse use until factor replacement therapy can be instituted?

• A. Apply warm, moist compresses
• B. Apply pressure for at least 1 minute
• C. Elevate the area above the level of the heart
• D. Begin passive range-of-motion unless the pain is severe

Correct answer: C

Rationale: Elevating the affected area above the level of the heart is the correct supportive measure for a child with hemophilia who has experienced trauma. This action helps reduce bleeding and swelling by promoting venous return and preventing further pooling of blood in the affected area. Applying warm, moist compresses (Choice A) may not be recommended as it can potentially increase bleeding by dilating blood vessels. Applying pressure for at least 1 minute (Choice B) can be helpful for minor cuts or wounds but may not be as effective in managing bleeding in a child with hemophilia. Beginning passive range-of-motion (Choice D) should be avoided as it can exacerbate bleeding and cause further damage in a child with hemophilia.
