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. What explanation should the nurse give a parent about the purpose of a tetanus toxoid injection for their child?

• A. Passive immunity is conferred temporarily.
• B. Long-lasting active immunity is conferred.
• C. Lifelong active natural immunity is conferred.
• D. Passive natural immunity is conferred temporarily.

Correct answer: B

Rationale: The correct answer is B: Long-lasting active immunity is conferred. Tetanus toxoid injection works by stimulating the child's body to produce its antibodies, providing long-lasting active immunity. Choice A is incorrect because passive immunity is not conferred for life; it is temporary and involves receiving antibodies rather than producing them internally. Choice C is incorrect as the immunity conferred by the tetanus toxoid injection is not lifelong natural immunity but rather active immunity stimulated by the body's immune response. Choice D is also incorrect since passive natural immunity is not conferred by the tetanus toxoid injection, and it is not temporary.

3. What are the most common signs and symptoms of leukemia related to bone marrow involvement?

• A. petechiae, infection, fatigue
• B. headache, papilledema, irritability
• C. muscle wasting, weight loss, fatigue
• D. decreased intracranial pressure, psychosis, confusion

Correct answer: A

Rationale: Petechiae, infection, and fatigue are common signs and symptoms of leukemia related to bone marrow involvement. Petechiae are small red or purple spots on the skin caused by bleeding under the skin due to low platelet counts. Infection susceptibility increases due to decreased white blood cells from compromised bone marrow function. Fatigue is a common symptom of anemia resulting from decreased red blood cell production. Choices B, C, and D are incorrect as they do not align with the typical signs and symptoms of leukemia associated with bone marrow dysfunction.

4. .A child with type 1 diabetes mellitus is being discharged from the hospital. What is important for the nurse to include in the discharge teaching?

• A. Monitor blood glucose levels once a day
• B. Follow a strict meal plan
• C. Administer insulin only when blood glucose is high
• D. Recognize signs of hypoglycemia

Correct answer: D

Rationale: Recognizing signs of hypoglycemia is crucial for managing type 1 diabetes mellitus and preventing complications.

5. During a routine monthly examination, a 5-month-old infant is brought to the pediatric clinic. What assessment finding should alert the nurse to notify the health care provider?

• A. Temperature of 99.5°F
• B. Blood pressure of 75/48 mm Hg
• C. Heart rate of 100 beats per minute
• D. Respiratory rate of 50 breaths per minute

Correct answer: D

Rationale: A respiratory rate of 50 breaths per minute in a 5-month-old infant is considered high and may indicate respiratory distress. Infants normally have a higher respiratory rate than older children and adults, but a rate of 50 breaths per minute is above the expected range. This finding warrants immediate attention as it may be indicative of an underlying respiratory issue or distress. Choice A (Temperature of 99.5°F) is within the normal range for body temperature and does not necessarily indicate a critical issue. Choice B (Blood pressure of 75/48 mm Hg) is not typically assessed in isolation for a 5-month-old infant during a routine examination, and the values provided are not indicative of a critical condition. Choice C (Heart rate of 100 beats per minute) is within the normal range for heart rate in infants and may not be a cause for immediate concern during a routine examination.
