A clinic nurse reviews the record of a child just seen by a doctor and diagnosed with suspected aortic stenosis. The nurse expects to note documentation of which clinical manifestation specifically found in this disorder?

Correct Answer: C

Rationale: Aortic stenosis is a condition characterized by the narrowing of the aortic valve, leading to reduced blood flow from the heart to the body. This narrowing restricts the amount of oxygenated blood that can reach various tissues, including muscles. As a result, individuals with aortic stenosis may experience exercise intolerance, as their muscles may not receive an adequate oxygen supply during physical activity. This can manifest as fatigue, shortness of breath, and overall decreased exercise capacity. Pallor (choice A) is a pale appearance that may be seen in anemia or other conditions affecting blood flow but is not specific to aortic stenosis. Hyperactivity (choice B) and gastrointestinal disturbances (choice D) are not typically associated with aortic stenosis.

Correct Answer: C

Rationale: Typhoid fever is primarily spread through contaminated food and water, usually due to poor sanitation practices. The bacteria responsible for typhoid fever, Salmonella Typhi, is typically found in food or water contaminated by the feces of an infected person. Contaminated air is not a significant mode of transmission for typhoid fever, making choice A incorrect. While waterborne transmission can occur, it is through contaminated water rather than specifically mineral water, making choice B incorrect. Therefore, the correct answer is C, as contaminated food and water are the main sources of transmission for typhoid fever.

Correct Answer: B

Rationale: In typhoid fever, the rash typically appears on the third day after symptoms first appear. This rash can help in diagnosing the disease along with other symptoms such as fever, malaise, and abdominal pain. Choices A, C, and D are incorrect because the rash in typhoid fever usually appears on the third day, not the second, fourth, or seventh day after the symptoms begin.

Correct Answer: D

Rationale: Enteric fever, caused by Salmonella typhi or paratyphi, is characterized by a continuous fever pattern. The fever typically persists without significant fluctuations, distinguishing it from diseases with intermittent or relapsing fever patterns. Pel-Ebstein fever, a cyclic pattern of fever seen in Hodgkin's lymphoma, is not associated with enteric fever. Relapsing fever is a characteristic of diseases like Borrelia recurrentis infection. Intermittent fever is seen in conditions like malaria.

Correct Answer: A

Rationale: The correct answer is A: 'The child vomits everything.' Vomiting everything is considered a danger sign in a child as it can lead to dehydration and other serious complications. Recognizing this sign early can help in timely intervention and management of the child's condition. Choices B and C are incorrect as diarrhea and headache, while concerning, are not specific danger signs highlighted in the Integrated Management of Neonatal and Childhood Illnesses.
