Which of the following attributes is associated with a relatively low risk for treatment-related toxicity?

Correct Answer: D

Rationale: Younger age is associated with better tolerance to treatment due to greater physiological reserve, unlike prior therapy or poor performance status, which increase toxicity risk. 'Discontinue treatment' is not an attribute.

Correct Answer: A

Rationale: Acetaminophen toxicity can lead to pyroglutamic acidosis, especially at high doses, causing severe anion gap metabolic acidosis.

Correct Answer: B

Rationale: The updated Jones Criteria for diagnosing Rheumatic Fever include major manifestations like arthritis, carditis, erythema marginatum, subcutaneous nodules, and Sydenham chorea. Option B correctly lists four of these.

Correct Answer: D

Rationale: Reentry is thought to be the culprit in most tachydysrhythmias. Reentry is a complex process in which a cardiac impulse continues to depolarize in a part of the heart after the main impulse has finished its path. Triggered activity occurs when an impulse is generated during or just after repolarization. Alterations in automaticity create electrolyte imbalances. Defective gap junctions are not related to tachydysrhythmias.

Correct Answer: C

Rationale: All listed options (A-D) are correct, but since this must be a single-answer question, C is a key dietary recommendation. Patients should monitor weight (A), get vaccinated (B), and manage exacerbations (D).
