1. What should be taught to the child and parents about using a peak flow meter for a child diagnosed with asthma?

• A. Use the device before taking medication
• B. Use the device during asthma attacks
• C. Record the best of three attempts
• D. Use the device after eating

Correct answer: C

Rationale: The correct answer is to 'Record the best of three attempts.' This method provides an accurate measure of peak expiratory flow using a peak flow meter. By taking the best of three attempts, the child and parents can obtain a more reliable assessment of the child's lung function. Choices A, B, and D are incorrect because using the device before taking medication, during asthma attacks, or after eating does not ensure an accurate measurement of peak flow, which is essential for managing asthma effectively. Monitoring peak flow regularly and accurately can help in adjusting asthma treatment plans and assessing response to medications.

2. You are managing a 10-month-old infant who has had severe diarrhea and vomiting for 3 days and is now showing signs of shock. You have initiated supplemental oxygen therapy and elevated the lower extremities. En route to the hospital, you note that the child's work of breathing has increased. What must you do first?

• A. Lower the extremities and reassess the child
• B. Begin positive pressure ventilations and reassess the child
• C. Place a nasopharyngeal airway and increase the oxygen flow
• D. Listen to the lungs with a stethoscope for abnormal breath sounds

Correct answer: A

Rationale: In this scenario, the infant is presenting with signs of respiratory distress, as evidenced by the increased work of breathing. Lowering the extremities can help reduce the workload on the diaphragm and improve respiratory mechanics. This action can be beneficial in optimizing the infant's breathing before considering more invasive interventions. Option B, initiating positive pressure ventilations, should be considered if the infant's condition deteriorates further and not as the first step. Option C, placing a nasopharyngeal airway and increasing oxygen flow, is not indicated as the primary intervention for increased work of breathing. Option D, listening to the lungs with a stethoscope, may provide additional information but is not the most urgent action needed in this situation.

3. The nurse is caring for a 15-year-old boy who has sustained burn injuries. The nurse observes the burn developing a purplish color with discharge and a foul odor. The nurse suspects which infection?

• A. Burn wound cellulitis.
• B. Invasive burn cellulitis.
• C. Burn impetigo.
• D. Staphylococcal scalded skin syndrome.

Correct answer: B

Rationale: The correct answer is B: Invasive burn cellulitis. Invasive burn cellulitis presents with the burn developing a dark brown, black, or purplish color with discharge and a foul odor. Burn wound cellulitis (choice A) typically involves redness, warmth, and swelling around the burn site. Burn impetigo (choice C) is a superficial infection characterized by honey-colored crusting. Staphylococcal scalded skin syndrome (choice D) is a condition caused by exotoxins from Staphylococcus aureus, leading to widespread skin peeling.

4. What is the priority intervention for a child with acute laryngotracheobronchitis upon admission?

• A. Pad the side rails of the crib.
• B. Arrange for a quiet, cool room.
• C. Place a tracheotomy set at the bedside.
• D. Obtain a recliner for a parent to stay.

Correct answer: C

Rationale: The correct priority intervention for a child with acute laryngotracheobronchitis is to place a tracheotomy set at the bedside. Acute laryngotracheobronchitis can lead to airway obstruction, making it essential to have the equipment readily available in case of emergency. Padding the side rails, arranging for a quiet room, or obtaining a recliner for a parent are not the immediate priorities in managing a child with this condition.

5. When teaching a class about trisomy 21, the instructor would identify the cause of this disorder as:

• A. nondisjunction.
• B. X-linked recessive inheritance.
• C. genomic imprinting.
• D. autosomal dominant inheritance.

Correct answer: A

Rationale: The correct answer is A: nondisjunction. Trisomy 21, also known as Down syndrome, is caused by nondisjunction, which is an error in cell division leading to an extra copy of chromosome 21. This additional genetic material alters the course of development and causes the characteristics associated with Down syndrome. Choices B, C, and D are incorrect. X-linked recessive inheritance refers to genetic disorders carried on the X chromosome, genomic imprinting involves gene expression based on parental origin, and autosomal dominant inheritance relates to disorders caused by a dominant gene on one of the non-sex chromosomes. In the case of trisomy 21, the cause is specifically related to the error in chromosome division, making nondisjunction the most appropriate answer.
