The client is brought to the emergency department due to drug poisoning. Which of the following nursing interventions is most effective in the management of the client’s condition?

Correct Answer: B

Rationale: Activated charcoal (B) is most effective for poisoning as it adsorbs toxins in the GI tract, reducing absorption. Gastric lavage (A) is less common now, cathartics (C) hasten elimination but don’t bind toxins, and milk (D) is ineffective.

Correct Answer: A

Rationale: Troponin-T (A) rises within 3-4 hours post-MI, making it an early and specific marker. Myoglobin (D) rises earlier but is less specific, CK-MB (B) peaks later, and LDH (C) is even later.

Correct Answer: C

Rationale: O negative blood (C) is the universal donor, safe when B negative isn’t available, as it lacks antigens to cause reactions. Other options (A, B, D) risk incompatibility.

Correct Answer: B

Rationale: The BCG vaccine is administered intradermally (ID, B) to stimulate immunity against tuberculosis effectively.

Correct Answer: C

Rationale: Limiting visitors (C) reduces stress on adrenal glands in adrenal insufficiency, preventing an addisonian crisis. Activity (A) increases stress, isolation (B) is unnecessary, and constipation (D) is secondary.
