Which of the following statement is NOT true about standards of care?

Correct Answer: C

Rationale: Standards guide practice (A), are evidence-based (B), ensure quality (D) 'vary by nurse' (C) isn't true, uniform, per regulation. C's variation contradicts consistency for Mr. Gary's care, making it untrue.

Correct Answer: C

Rationale: Safety protocols reduce harm (A), guide care (B), are nursing (D) 'only for emergencies' (C) isn't true, used always, per standards. C's limit contradicts broad use, like Mr. Gary's routine care, making it untrue.

Correct Answer: A

Rationale: Treating pain first is priority setting (A) need-based order, per definition. Decision-making (B) chooses, literacy (C) understanding, coordination (D) organization not priority-specific. A fits the nurse's focus on Mr. Gary's urgency, making it correct.

Correct Answer: B

Rationale: Deductibles are paid before insurance kicks in (B), per definition e.g., Mr. Gary's upfront cost. Not after (A), are insurance (C), not all (D) threshold-based. B truly defines deductibles' role, triggering coverage, making it correct.

Correct Answer: A

Rationale: Prolonged vomiting and gastric lavage lose stomach acid (HCl), causing metabolic alkalosis elevated pH, not decreased (acidosis). Bicarbonate rises as the body compensates, not oxygen or osmolarity, which are unrelated. Nurses monitor for alkalosis symptoms (e.g., tetany), correcting with fluids like saline, restoring acid-base balance disrupted by gastric content loss.
