Question 1 of 5
See the syringe diagram, what part is #7? (Assuming #7 refers to a common syringe part; no diagram provided, so standard parts assumed.)
Correct Answer: B
Rationale: 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. The plunger, often numbered high in diagrams, moves to draw or inject; its dynamic function in volume control makes it a likely #7 candidate. 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. The tip connects the needle; a minor component, it's rarely highlighted as #7, overshadowed by the plunger or barrel in functional importance.
Question 2 of 5
When categorizing medications, drug classifications may be defined by the effects of the drug and:
Correct Answer: A
Rationale: Classifications like 'analgesics' pair effects (pain relief) with symptoms (pain); this pharmacological basis groups drugs by therapeutic purpose and mechanism. Dosage varies within classes; it's not a defining trait, as classifications focus on action (e.g., beta-blockers), not specific amounts administered.
Tolerance is patient-specific, not a classification criterion; drugs are grouped by effect and symptom relief, not individual response variations. Nursing implications guide administration, not classification; categories stem from pharmacology (e.g., antihypertensives), not care protocols or implications.
Question 3 of 5
Which of these is the correct way for a nurse to document medication administration?
Correct Answer: C
Rationale: Recording at shift's end risks memory errors or omissions; delayed documentation compromises accuracy and legal accountability for controlled substances and patient care. Pharmacy technicians don't administer drugs; nurses document their own actions, ensuring responsibility and precision in the medication administration record. Immediate recording post-administration ensures accuracy, timeliness, and compliance with standards; it reflects real-time events, reducing errors in patient care documentation. Recording others' actions is inaccurate and unethical; nurses must document only their administrations, maintaining individual accountability and patient safety.
Question 4 of 5
When preparing to administer an intradermal injection to an adult, the nurse ensures that the dose amount does not exceed 0.1 mL. A 1 mL tuberculin syringe is used with a 25-gauge needle and is administered at which angle?
Correct Answer: B
Rationale: A 12-degree angle is too shallow, increasing the risk of incorrect placement and ineffective administration of the intradermal injection. The 15-degree angle ensures precise intradermal placement, forming a wheal that indicates proper administration into the dermis for optimal absorption. A 30-degree angle places the medication too deep into subcutaneous tissue, compromising intended drug absorption. A 45-degree angle results in subcutaneous rather than intradermal injection, altering the drug's effectiveness and purpose.
