See the syringe diagram, what part is #7? (Assuming #7 refers to a common syringe part; no diagram provided, so standard parts assumed.)

Barrel

Plunger

Needle

Tip

Answer and Explanation

The Correct Answer is B

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: Promising instant relief is misleading; most drugs take time, and false expectations may erode trust, reducing cooperation in a toddler’s care.

Choice B reason: Calling it candy is unethical; it risks future candy confusion with drugs, potentially leading to accidental ingestion, unsafe for a 3-year-old.

Choice C reason: Confident explanation suits a toddler’s understanding; it builds trust, reduces fear, and ensures cooperation by clearly stating purpose and process age-appropriately.

Choice D reason: Firm insistence may scare a toddler; without explanation, it lacks reassurance, potentially increasing resistance and distress during medication administration.

A. 62.5 mL/hr B. 125 mL/hr C. 250 mL/hr D. 500 mL/hr

Correct Answer is A

Explanation

Choice A reason: Flow rate is volume divided by time; 250 mL over 4 hours equals 62.5 mL/hr, ensuring safe transfusion pacing to avoid fluid overload or hemolysis.

Choice B reason: 125 mL/hr assumes 250 mL over 2 hours; this doubles the ordered rate, risking circulatory overload and transfusion reactions in a standard protocol.

Choice C reason: 250 mL/hr infuses the unit in 1 hour; this rapid rate exceeds safe limits, potentially causing hypertension or pulmonary edema in vulnerable patients.

Choice D reason: 500 mL/hr is far too fast, implying 250 mL in 30 minutes; this dangerous speed could trigger severe hemolytic reactions or cardiovascular collapse.
