The nurse is planning to inspect a client's apical heart impulses. What should the nurse do to ensure an accurate assessment of this organ?

A. Use tangential lighting: Tangential lighting is not typically used for assessing heart impulses; it is more useful for examining surface characteristics of the skin. B. Assist the client to a standing position: The client should be in a supine or semi-recumbent position for accurate inspection of apical heart impulses, not standing. C. Use perpendicular lighting: Perpendicular lighting is crucial for accurately visualizing apical heart impulses, as it helps to clearly observe the movement of the heart against the chest wall. D. Focus a penlight on the client's chest: While a penlight can be used in physical assessments, perpendicular lighting is more effective for clearly seeing the apical heart impulses.
