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: Convergence and pupil constriction are accommodation reflexes, not corneal light reflex, which tests alignment. Light reflection symmetry indicates eye alignment, so this incorrect for the reflex’s purpose.
Choice B reason: Pupil constriction is a pupillary reflex, not corneal light reflex. The corneal reflex involves light reflection on corneas, assessing alignment, not pupil response, so this is incorrect.
Choice C reason: Macular focus is related to visual acuity, not corneal reflex, light reflex, which checks eye alignment via light reflection. Symmetric reflection is key, so this incorrect for the reflex’s indication.
Choice D reason: A normal corneal reflex shows light reflecting in the same spot on both corneas, indicating proper eye alignment. This is the definition of the reflex, making it the correct choice for eye assessment.
Correct Answer is A
Explanation
Choice A reason: Costovertebral angle tenderness is a classic sign of pyelonephritis, indicating kidney infection or inflammation. Percussing this area elicits pain in renal conditions, making it the correct condition to assess for tenderness.
Choice B reason: Cholecystitis causes pain in the right upper quadrant, not the costovertebral angle. Kidney-related pyelonephritis is linked to this tenderness, so this is incorrect for the assessment focus.
Choice C reason: Gastric ulcers cause epigastric pain, not costovertebral tenderness, which is renal-specific. Pyelonephritis is the condition associated with this sign, so this is incorrect for the suspected condition.
Choice D reason: Pancreatitis presents with abdominal pain, not costovertebral angle tenderness, which indicates kidney issues. Pyelonephritis is the relevant condition, so this is incorrect for the assessment.
