A patient consumes 120 mL of orange juice and 120 mL of milk for breakfast, 260 mL of coffee for lunch, and 90 mL of an ice pop and 120 mL of ice cream for dinner. Calculate the intake for the 6 AM to 6 PM shift.
610 mL
710 mL
810 mL
910 mL
The Correct Answer is B
Choice A reason: 610 mL omits ice cream (120 mL); total is 120 + 120 + 260 + 90 + 120 = 710 mL; this undercalculation misses a key liquid intake component.
Choice B reason: 710 mL sums all: 120 (juice) + 120 (milk) + 260 (coffee) + 90 (ice pop) + 120 (ice cream); melted solids count as fluid, matching clinical standards.
Choice C reason: 810 mL overestimates; no additional fluids are listed beyond 710 mL; this error likely adds non-existent intake, skewing the total inaccurately.
Choice D reason: 910 mL vastly exceeds reality; it may double-count or invent fluids; only 710 mL is supported by the listed consumption data provided.

Correct Answer is B
Explanation
Choice A reason: The barrel holds the medication; it’s the main body, not typically #7, and its static role doesn’t involve direct manipulation like other parts.
Choice B reason: The plunger, often numbered high in diagrams, moves to draw or inject; its dynamic function in volume control makes it a likely #7 candidate.
Choice C reason: The needle pierces tissue; usually a lower number, it’s distinct from the syringe’s operational core, less likely to be #7 in standard layouts.
Choice D reason: The tip connects the needle; a minor component, it’s rarely highlighted as #7, overshadowed by the plunger or barrel in functional importance.
Correct Answer is C
Explanation
Choice A reason: Topical applies to skin or mucous surfaces broadly; gum/jaw placement is specific to buccal, not the general external or mucosal topical category.
Choice B reason: Oral means swallowed; buccal drugs stay in the mouth for absorption, avoiding the digestive tract, making this an incorrect route classification.
Choice C reason: Buccal involves placement between gum and cheek; it allows direct mucosal absorption into the bloodstream, bypassing first-pass metabolism effectively.
Choice D reason: Sublingual is under the tongue; gum/jaw specifies buccal, as sublingual targets a different oral site with distinct absorption dynamics.
