The nurse will give Amoxicillin 25 mg/kg as ordered. How many tablet(s) of Amoxicillin is needed if the medication is supplied as 500 mg tablets and the patient weighs 10 kg?
0.5 tablet
0.75 tablet
1.25 tablets
0.25 tablet
The Correct Answer is A
Choice A reason: The dose is 25 mg/kg × 10 kg = 250 mg. With 500 mg tablets, 250 mg requires 250 ÷ 500 = 0.5 tablet. This precise calculation ensures the correct dose, minimizing the risk of under- or overdosing, making this the correct choice.
Choice B reason: A 0.75 tablet dose equals 375 mg (0.75 × 500 mg), exceeding the ordered 250 mg. This could lead to toxicity, as Amoxicillin overdosing may cause gastrointestinal or renal issues, making this an incorrect and potentially harmful choice.
Choice C reason: A 1.25 tablet dose equals 625 mg (1.25 × 500 mg), significantly more than the ordered 250 mg. This excessive dose risks severe side effects, including allergic reactions or organ stress, making this an unsafe and incorrect choice.
Choice D reason: A 0.25 tablet dose equals 125 mg (0.25 × 500 mg), less than the ordered 250 mg. This underdose could lead to ineffective treatment, increasing the risk of bacterial resistance, making this an incorrect choice for the prescribed dose.

Correct Answer is D
Explanation
Choice A reason: Diet and weight provide partial insight into health but are incomplete. Diet is subjective and hard to quantify, and weight alone does not account for growth patterns or proportionality, making it less comprehensive than height and weight.
Choice B reason: Temperature and pulse reflect acute physiological status, not overall health. These vital signs can be normal despite chronic conditions or growth issues, making them inadequate as a primary index for a child’s general health status.
Choice C reason: Height and strength are not typically paired as a standard health index. Strength is subjective and difficult to measure consistently in children, while height alone misses weight-related nutritional status, making this less effective.
Choice D reason: Height and weight are key indicators of a child’s general health, reflecting growth, nutritional status, and development. These measurements, plotted on growth charts, allow comparison to age-specific norms, making them the best index for assessing overall health.
Correct Answer is A
Explanation
Choice A reason: Tenderness in the right lower quadrant on light palpation is a classic sign of appendicitis, as the appendix is located in this region. Inflammation causes localized peritoneal irritation, leading to pain, which may be accompanied by rebound tenderness or guarding, making this the correct structure.
Choice B reason: The spleen is located in the left upper quadrant, not the right lower quadrant. Tenderness in the right lower quadrant does not correspond to splenic pathology, such as splenomegaly or rupture, making this an incorrect structure for the described finding.
Choice C reason: The gallbladder is in the right upper quadrant, where tenderness might suggest cholecystitis. Right lower quadrant tenderness does not align with gallbladder pathology, as its anatomical location is distinct, making this an incorrect structure for the observed symptom.
Choice D reason: The spine is a midline structure, and tenderness in the right lower quadrant is unrelated to spinal pathology. Spinal issues typically cause back or radicular pain, not localized abdominal tenderness, making this an incorrect choice for the finding.
