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 C
Explanation
Choice A reason: Checking with the physician delays addressing the patient’s misunderstanding. The HPV vaccine does not treat existing infections or warts, as it is preventive, making this response less direct and informative than needed.
Choice B reason: The HPV vaccine is not limited to those not yet sexually active; it is recommended up to age 26, even for those with sexual history. This statement is outdated and incorrect, as vaccination can still benefit some with prior exposure.
Choice C reason: The HPV vaccine prevents new HPV infections but does not treat existing infections or genital warts, which are caused by specific HPV strains. Since the patient already has warts, the vaccine won’t help, making this the correct response.
Choice D reason: While the HPV vaccine is approved for ages 9–26, it does not treat existing infections or warts. Starting it without clarifying its preventive role misleads the patient, making this an incorrect and misleading response.
Correct Answer is B
Explanation
Choice A reason: A normal tympanic membrane is not white with prominent capillaries. Such an appearance may indicate inflammation or infection (e.g., otitis media), where increased vascularity or opacity occurs, making this an abnormal and incorrect characteristic.
Choice B reason: A normal tympanic membrane is pearly gray, slightly translucent, with a visible cone of light reflecting off its taut surface. This reflects healthy middle ear anatomy, with no fluid or inflammation, making this the correct description.
Choice C reason: A pulled-in tympanic membrane suggests negative middle ear pressure, often due to eustachian tube dysfunction, not a normal finding. The normal membrane is flat or slightly concave, making this an incorrect characteristic.
Choice D reason: Light pink with a slight bulge suggests inflammation or fluid (e.g., otitis media), not a normal tympanic membrane. Normal membranes are pearly gray and flat, not pink or bulging, making this an incorrect description.
