Which is a normal characteristic of lymph nodes in a healthy adult patient?
Large and fixed to the tissue
Large and non-mobile
Granular texture
Not palpable
The Correct Answer is D
Choice A reason: Large, fixed lymph nodes suggest pathology, such as malignancy or chronic infection, as they indicate adherence to surrounding tissues. In healthy adults, lymph nodes are typically small and not fixed, making this an abnormal and incorrect characteristic.
Choice B reason: Large, non-mobile lymph nodes may indicate infection or malignancy, as healthy nodes are usually small and mobile. Non-mobility suggests tissue infiltration, which is pathological, making this an incorrect description of normal lymph node characteristics.
Choice C reason: Granular texture is not a standard term for describing lymph nodes. Healthy nodes, when palpable, feel smooth and soft. Granular suggests abnormality, possibly infection or malignancy, making this an inaccurate characteristic for healthy lymph nodes.
Choice D reason: In healthy adults, lymph nodes are typically not palpable, as they are small, soft, and non-tender, blending into surrounding tissues. Palpable nodes often indicate inflammation or pathology, making this the correct description of a normal finding.

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: The systolic pressure (top number) measures arterial pressure during heart contraction, accurately explaining 118/82 mm Hg. This clear, correct definition educates the patient, making it the best reply.
Choice B reason: Diastolic pressure (bottom number) reflects arterial pressure at rest, not stroke volume. Systolic pressure is correctly defined as contraction pressure, so this is incorrect for explaining the numbers.
Choice C reason: Dismissing blood pressure as complex is unhelpful; both numbers matter. Systolic pressure is accurately defined as heart contraction pressure, so this is incorrect for patient education.
Choice D reason: Stating the numbers are normal (118/82 is prehypertension) avoids explaining their meaning. Defining systolic pressure clarifies the reading, so this is incorrect for answering the question.
