Free CCHT Exam Questions That Helps Candidates Pass

Blood pump alarms often result from open doors or tubing issues. The pump should not be restarted until problem is corrected. Ignoring (B) or adding saline (C) is unsafe. Disconnecting (D) may not be needed if issue is mechanical.

Chemical exposures must be flushed immediately for a minimum of 15 minutes. After irrigation, seek medical evaluation and complete incident reporting. Rubbing (C) worsens injury. Delaying reporting (B, D) risks long-term harm. OSHA mandates access to eyewash stations in dialysis areas.

Dialyzer choice is part of prescription. CCHTs must not independently alter it. Proper action is education, documentation, and RN notification. Options B–D are inappropriate and unsafe.

Explanation (150–250 words):

Hypocalcemia manifests as neuromuscular irritability: tingling (perioral/numbness), muscle cramps, and sometimes tetany. Causes in dialysis patients include low-calcium dialysate, removal of calcium, or secondary hyperparathyroidism. The CCHT must recognize signs quickly and notify the RN/provider. Hyperkalemia (B) causes arrhythmias and muscle weakness, not tingling. Hyponatremia (C) produces confusion and seizures. Hyperphosphatemia (D) is usually asymptomatic until chronic complications develop. Prompt recognition ensures safety and prevents worsening complications.

Machine settings are part of the dialysis prescription, which only providers can change. Patients must be educated that self-adjustments are unsafe. Ignoring (B), passive recording (C), or silencing alarms (D) compromises safety and legal standards. Documentation and RN notification are required.
