A patient is being assessed for range-of-joint movement. The nurse asks him to move his arm in toward the center of his body. What is this movement called?
Extension
Adduction
Flexion
Abduction
The Correct Answer is B
Choice A reason: Extension is straightening a joint, not moving toward the body’s midline. Adduction describes the arm moving inward, so this is incorrect for the described joint movement.
Choice B reason: Adduction is the movement of a limb toward the body’s midline, such as bringing the arm inward. This matches the nurse’s description, making it the correct term for the movement.
Choice C reason: Flexion is bending a joint, like elbow curling, not moving toward the midline. Adduction is specific to inward motion, so this is incorrect for the arm’s movement.
Choice D reason: Abduction is moving away from the midline, opposite to the described action. Adduction is the term for inward movement, so this is incorrect for the joint motion described.

Correct Answer is A
Explanation
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 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.
