The parent of a toddler calls the nurse, asking about croup. What is a distinguishing manifestation of croup?
Stridor
Wheezes
Crackles
Rhonchi
The Correct Answer is A
Choice A reason: Stridor is a high-pitched, harsh sound that occurs during inspiration. It is caused by the narrowing of the upper airway due to inflammation and edema. Stridor is a characteristic sign of croup, also known as laryngotracheobronchitis.
Choice B reason: Wheezes are high-pitched, musical sounds that occur during expiration. They are caused by the narrowing of the lower airway due to bronchoconstriction or mucus. Wheezes are more common in asthma than in croup.
Choice C reason: Crackles are fine, crackling sounds that occur during inspiration. They are caused by the opening of collapsed or fluid-filled alveoli. Crackles are more common in pneumonia or heart failure than in croup.
Choice D reason: Rhonchi are low-pitched, snoring sounds that occur during expiration. They are caused by the vibration of mucus in the large airways. Rhonchi are more common in bronchitis or cystic fibrosis than in croup.

Correct Answer is ["A","B"]
Explanation
Choice A reason: This response is correct because antibiotics are indicated for bacterial pneumonia caused by staphylococcus. Antibiotics help to fight the infection and prevent complications.
Choice B reason: This response is correct because cluster care means grouping nursing interventions together to minimize the disruption of the child's rest and sleep. Cluster care helps to conserve the child's energy and promote healing.
Choice C reason: This response is not correct because fluids are essential for hydration and thinning of secretions in pneumonia. Fluids help to prevent dehydration and facilitate expectoration of mucus.
Choice D reason: This response is not correct because antitussive agents are not recommended for pneumonia. Antitussive agents suppress the cough reflex, which is a natural mechanism to clear the airways of secretions. Antitussive agents may increase the risk of respiratory infection and atelectasis.
Correct Answer is A
Explanation
Choice A reason: This is correct because the ordered dose of Amoxicillin is within the safe range for a 3-year-old weighing 14 kg. The daily dose of Amoxicillin is 175 mg x 3 = 525 mg. The safe dose range for a 14 kg child is 20-40 mg/kg/day, which is 280-560 mg/day. Therefore, the ordered dose is safe.
Choice B reason: This is incorrect because the ordered dose of Amoxicillin is not above the safe range for a 3-year-old weighing 14 kg. It is not necessary to reduce the dose or report it to the prescriber.
