The nurse must check vital signs on a 2-year-old boy who is brought to the clinic for his 24-month checkup. Which criteria should the nurse use in determining the appropriate-size blood pressure cuff?
The cuff bladder covers 50% to 66% of the length of the upper arm.
The cuff is labeled "toddler.".
The cuff bladder width is approximately 40% of the circumference of the upper arm.
The cuff bladder length covers 80% to 100% of the circumference of the upper arm.
The Correct Answer is A
The correct answer is choice A. The cuff bladder covers 50% to 66% of the length of the upper arm.
Choice A rationale:
Selecting a blood pressure cuff with a bladder that covers 50% to 66% of the length of the upper arm is the appropriate criterion for determining the cuff size for a 2-year-old boy. This range ensures accurate blood pressure measurement by ensuring a proper fit on the arm. If the cuff bladder is too small or too large, it can result in inaccurate readings.
Choice B rationale:
The label "toddler" on the cuff might be helpful in identifying the intended age group, but it doesn't provide precise measurements for cuff sizing. Relying solely on a label might not account for variations in arm sizes within the toddler age group.
Choice C rationale:
The cuff bladder width being 40% of the circumference of the upper arm might not be as accurate as the length-based criterion. A cuff that fits the arm's length is more critical in ensuring proper inflation and accurate blood pressure measurement.
Choice D rationale:
The cuff bladder length covering 80% to 100% of the circumference of the upper arm might result in an excessively large cuff for a 2-year-old, which can lead to inaccurate readings. Length-based sizing is more appropriate for accuracy in this scenario.

Correct Answer is C
Explanation
The correct answer is choice C. Asthma.
Choice A rationale:
A foreign body in the trachea can cause acute respiratory distress and a sudden cough, but it is unlikely to cause chronic nonproductive cough and diffuse wheezing during the expiratory phase of respiration. The symptoms in the scenario are more suggestive of a chronic condition.
Choice B rationale:
Bronchiolitis primarily affects infants and young children, causing symptoms such as fever, rhinorrhea, and wheezing. While wheezing can be present, the diffuse wheezing during the expiratory phase described in the scenario is more characteristic of asthma.
Choice C rationale:
Asthma is characterized by chronic inflammation of the airways, leading to episodes of bronchoconstriction and increased airway reactivity. The chronic, nonproductive cough and diffuse wheezing during the expiratory phase are classic signs of asthma. Expiratory phase wheezing occurs due to the narrowing of the smaller airways during expiration.
Choice D rationale:
Pneumonia is an infection of the lung tissue and can cause productive cough, fever, and crackles on auscultation. While wheezing might occur in pneumonia due to inflammation and narrowing of the airways, it's not the most likely cause of the symptoms described in the scenario.
Correct Answer is C
Explanation
The correct answer is choice C: Administering penicillin.
Choice A rationale:
Imposing strict bed rest for 4 to 6 weeks. This choice is not the most appropriate therapeutic management for rheumatic fever. While rest is important during the acute phase, strict bed rest for 4 to 6 weeks is excessive and could lead to physical deconditioning and psychological distress for the child.
Choice B rationale:
Administering corticosteroids if chorea develops. This choice is relevant to the management of rheumatic fever but is not the primary treatment. Chorea is a movement disorder that can occur as a complication of rheumatic fever. Corticosteroids may be used to manage chorea symptoms, but they are not the mainstay of treatment for rheumatic fever itself.
Choice C rationale:
Administering penicillin. This is the correct choice. Penicillin is the mainstay of treatment for rheumatic fever. It helps eradicate the group A streptococcal infection that triggers the inflammatory response leading to rheumatic fever. Penicillin is essential to prevent further complications such as rheumatic heart disease.
Choice D rationale:
Avoiding salicylates (aspirin). This choice is also relevant to the management of rheumatic fever. Salicylates, including aspirin, are used to relieve symptoms and reduce inflammation. However, in children with acute rheumatic fever, salicylates are contraindicated due to the risk of developing Reye's syndrome, a serious condition that affects the brain and liver.
