Sepsis during dialysis can present with fever, altered mental status, and seizures. RN/provider must be notified immediately. Hypoglycemia (B) and hypernatremia (C) present differently. Hypotension (D) does not cause high fever.

Excessive negative arterial pressure suggests resistance between the vascular access and the blood pump—most often from a kinked arterial line, poor needle position, or clot. This must be corrected immediately. Venous infiltration (C) would affect venous pressures. Dialysate flow (D) does not influence arterial pressure. Ignoring (B) risks collapse of access or air aspiration.

EPA and OSHA require disinfectants to remain wet for full contact time to ensure pathogen kill. Usually 1–10 minutes depending on product. Short contact (B, C) is ineffective. Using only if visibly soiled (D) misses microscopic pathogens.

Unlabeled chemicals violate OSHA Hazard Communication Standard. They must not be used until properly identified. Using based on appearance (B), smell (C), or mixing (D) is unsafe.

Overheated dialysate can cause hemolysis, while low temperatures can cause hypothermia. Always verify with independent thermometer and correct issue before resuming. Options B–D are unsafe.
