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 B

Explanation

Choice A reason: Juice may alter absorption; liquid can dilute or degrade some drugs, and taste may deter intake, reducing effectiveness compared to soft food.

Choice B reason: Applesauce masks taste and aids swallowing; it ensures crushed medication is consumed fully, maintaining dose integrity without altering pharmacokinetics significantly.

Choice C reason: Water may not mask bitterness; some drugs dissolve poorly or lose potency, and patients may not finish it, risking incomplete dosing.

Choice D reason: Meat or vegetables may bind drugs; uneven distribution or strong flavors could reduce intake, compromising the full therapeutic dose delivery.

A. Blood pressure B. Temperature C. Pulse D. Respiratory

Correct Answer is D

Explanation

Choice A reason: Blood pressure matters but isn’t primary; opioids rarely cause acute hypotension initially, and respiratory depression is a more immediate life-threatening risk.

Choice B reason: Temperature is unrelated; opioids don’t primarily affect fever, and this assessment doesn’t address the critical safety concern of opioid administration.

Choice C reason: Pulse is secondary; opioids may slow heart rate mildly, but respiratory suppression is the urgent risk, requiring priority monitoring before dosing.

Choice D reason: Respiratory rate is critical; opioids depress the brainstem, risking apnea, and assessing breathing ensures safety before administering this high-risk medication.
