Experience the Quality With Free CCHT Exam Questions That Helps Candidates Pass

Contaminated gowns are OSHA-regulated items. They must be disposed of or laundered by facility-approved services. Reuse (B), storage (C), or washing at home (D) violates infection control standards.

OSHA requires PPE when handling contaminated equipment. Immediate correction protects both patients and staff. Ignoring (B) or covering (C) violates safety rules. Delayed reporting (D) allows continued unsafe practice.

Explanation (150–250 words):

Hemolysis occurs when red blood cells rupture, releasing free hemoglobin, which can be seen as cherry-red plasma. Causes include overheated dialysate, chlorine/chloramine contamination, or kinks causing negative pressure. The CCHT must stop the pump immediately, clamp lines, do not return blood, and notify RN/provider. Hypotension (B) causes pallor and dizziness, not cherry-red blood. Hyperkalemia (C) is usually pre-dialysis with arrhythmias. Dialyzer clotting (D) leads to dark streaking, not hemolysis. Rapid recognition prevents cardiac arrest.

High TMP means blood side resistance is increasing—clotting, fouling, or high UF goals. It does not indicate normal clearance (B). Dialysate flow (C) or disinfectant residue (D) do not directly raise TMP. RN should be notified to assess whether dialyzer needs changing.

Air embolism presents suddenly with chest pain, dyspnea, confusion, or collapse. CCHT must clamp venous line, stop pump, position patient left side Trendelenburg, and notify RN immediately. Hypoglycemia (B) and hypocalcemia (C) do not present this way. Hyperphosphatemia (D) is chronic, not acute.
