What is the expected language skill level for a 2-3 year old toddler?
The toddler would not speak but be able to follow commands.
The toddler would speak in two-word sentences using both a noun and a verb.
The toddler would speak clearly with all words understandable.
The toddler would know 800-900 words by age 2. . .
The Correct Answer is B
Choice A rationale
This is a significant underestimation of a 2-3 year old's language skills. While a toddler can follow commands, their expressive language is also developing rapidly. They typically transition from single words to multi-word sentences and have a vocabulary of several hundred words. The lack of speech would be a cause for concern and would require further developmental evaluation.
Choice B rationale
This is the expected language skill level for a 2-3 year old toddler. At this stage, a toddler's vocabulary expands significantly, and they begin to combine words into simple sentences. This two-word stage, often called "telegraphic speech," is a key milestone and indicates the child is beginning to understand and apply grammatical rules.
Choice C rationale
This is an overestimation of a 2-3 year old's language skills. While their vocabulary is growing, their speech is not typically fully clear or understandable to all listeners. They may still mispronounce words or omit certain sounds. Full clarity of speech is usually not achieved until 4 or 5 years of age.
Choice D rationale
This is an overestimation of a 2-3 year old's vocabulary. The typical vocabulary for a 2-year-old is around 50 words, and by age 3, it may increase to around 200-300 words. A vocabulary of 800-900 words is more characteristic of a 4 to 5 year old and is not the expected norm for this age group.

Correct Answer is ["A","D"]
Explanation
Choice A rationale
Coronary thrombosis is a life-threatening complication where a blood clot forms in a coronary artery, leading to a myocardial infarction. Kawasaki disease causes inflammation of the blood vessels (vasculitis), which can damage the endothelium of the coronary arteries. This damage creates a site for clot formation, which can occlude blood flow and cause severe myocardial ischemia or death.
Choice B rationale
Coronary stenosis is a narrowing of the coronary arteries. While it can be a long-term complication of Kawasaki disease, leading to restricted blood flow, it is generally considered a less immediate and life-threatening complication than an acute thrombosis or aneurysm. The stenosis itself is not the most serious acute event, although it does increase the risk of later cardiac events.
Choice C rationale
A decreased sedimentation rate, or ESR, would not be a complication. In fact, an elevated ESR is a hallmark of the acute inflammatory process in Kawasaki disease. The ESR measures the rate at which red blood cells settle, which is increased during inflammation due to the presence of acute-phase proteins. A decreased ESR would indicate a reduction in inflammation, not a complication.
Choice D rationale
Coronary artery aneurysm is a primary serious complication of Kawasaki disease. The vasculitis can weaken the arterial walls, leading to the formation of aneurysms. These aneurysms can rupture, causing a hemorrhage, or they can be the site of a thrombosis. Aneurysms are a significant source of long-term morbidity and mortality in children with the disease.
Choice E rationale
Hypocoagulability, or a reduced ability to form blood clots, is not a complication of Kawasaki disease. In the acute phase, patients are more likely to be in a hypercoagulable state due to the systemic inflammatory response. This increased risk of clotting is what makes coronary thrombosis a significant concern, not hypocoagulability
Correct Answer is C
Explanation
Choice A rationale
Throwing away all stuffed animals is an unnecessary and extreme measure. The lice and nits are unlikely to survive for an extended period off the host. Sealing the items in an airtight bag for a specific duration is a more cost-effective and practical method to ensure any lice or nits are suffocated and die, preventing re-infestation.
Choice B rationale
Changing bed linen every 12 hours is not scientifically necessary. Lice and nits can survive for a limited time off the scalp, but not long enough to warrant such frequent changes. Changing and washing bedding and clothing in hot water and drying them on high heat once a day for a few days is sufficient to kill any lice or nits that may have fallen off.
Choice C rationale
Sealing all non-washable items in airtight bags for two weeks is a highly effective method. Lice and nits require a human host for survival, feeding on blood. Without a host, they will die from starvation within one to two weeks. Sealing items suffocates any remaining lice and ensures that any nits that may hatch will also die without a food source.
Choice D rationale
Soaking all hair items in alcohol is not a standard or recommended practice. While alcohol can be a disinfectant, it is not the primary method for treating lice and may damage the items. Combing with a fine-toothed nit comb, washing in hot water, or sealing items are more proven and safer methods for eradicating lice from personal belongings and preventing re-infestation.
