The nurse teaches parents about drowning risks.
Which group is at greatest risk?
Preschoolers.
Toddlers.
Infants.
Teenagers.
The Correct Answer is B
Choice A rationale
Preschoolers (ages 3-5 years) are at risk for drowning, often due to their increasing independence and exploration without fully understanding water hazards. However, they are generally more coordinated than toddlers and may have some understanding of safety rules.
Choice B rationale
Toddlers (ages 1-3 years) are at the greatest risk for drowning due to their natural curiosity, developing mobility, and lack of awareness of danger. They can wander off and fall into pools, bathtubs, or even buckets of water. Their head-to-body ratio makes it difficult for them to lift their heads if they fall face-first into water.
Choice C rationale
Infants (under 1 year) are dependent on caregivers and are typically supervised closely around water. While they can drown in shallow water, their lack of mobility reduces their risk compared to toddlers who are actively exploring their environment.
Choice D rationale
Teenagers, while still at risk for drowning, often due to risk-taking behaviors around water or substance use, generally have a better understanding of water safety than younger children and are more physically capable in the water.

Correct Answer is C
Explanation
Choice A rationale
A high elevation in the white blood cell count, or leukocytosis, is an expected inflammatory response in appendicitis. While an elevated WBC count (normal range typically 4,500 to 11,000 cells/mcL) indicates infection or inflammation, it does not necessarily signal immediate, life-threatening complications requiring immediate intervention.
Choice B rationale
Guarding, which is the tensing of abdominal muscles upon palpation, and rebound tenderness, pain that worsens when pressure is released, are classic signs of peritoneal irritation associated with appendicitis. These findings suggest inflammation of the peritoneum but do not indicate an immediate, critical emergency in the same way as sudden pain relief.
Choice C rationale
Sudden relief of pain in a child with appendicitis, followed by a rigid abdomen and fever, is a critical sign of a ruptured appendix and subsequent peritonitis. The rupture releases the pressure causing the initial pain, but the spillage of bowel contents leads to widespread inflammation of the peritoneum, a serious and potentially life-threatening condition requiring immediate surgical intervention to prevent sepsis and other complications.
Choice D rationale
Abdominal tenderness in the right lower quadrant (RLQ), often referred to as McBurney's point, is a characteristic finding in appendicitis due to the inflammation of the appendix in this anatomical location. While it warrants investigation and treatment, localized tenderness alone does not indicate an immediate, life-threatening complication.
Correct Answer is B
Explanation
Choice A rationale
At 12 months, a child typically says their first single words with meaning, such as "mama" or "dada," and may understand simple commands. Reaching a vocabulary of 50 words is not expected at this early stage of language development.
Choice B rationale
By 24 months, most toddlers have experienced a significant language explosion and are typically able to say at least 50 words and are beginning to combine two words into simple phrases. This is a key milestone in language development.
Choice C rationale
At 36 months, a child's vocabulary has typically expanded significantly, often exceeding several hundred words. They are also using longer and more complex sentences. Saying only 50 words at this age would be considered a developmental delay.
Choice D rationale
At 15 months, children are typically in the stage of building their vocabulary beyond the initial single words. While some may be approaching a larger vocabulary, consistently saying 50 words is more characteristic of older toddlers closer to 24 months.
