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

CCHTs cannot alter or recommend stopping medications. The safe response is referral to RN/provider. Options B–D are unsafe and unprofessional.

Falling conductivity suggests inadequate delivery of concentrates (acid or bicarb), often due to empty containers or disconnected lines. High sodium dialysate (B) would cause high conductivity. Dialyzer clotting (C) affects pressures, not conductivity. Blood pump malfunction (D) affects flow, not dialysate.

Without bicarbonate, dialysate is unsafe and acidic. Machine must be bypassed, jug replaced, and safety rechecked. Options (B–D) are unsafe and noncompliant.

Skipping conductivity checks endangers patients. Addressing immediately and escalating ensures compliance. Ignoring (B, C) or falsifying (D) is unsafe and unethical. CCHTs are accountable for ensuring safety procedures are followed.

Explanation (150–250 words):

Severe hyponatremia produces neurologic symptoms such as confusion, restlessness, seizures, and blurred vision. This can occur from excess fluid intake, dilutional states, or improper dialysate sodium. The CCHT must notify the RN immediately. Hyperkalemia (B) presents with arrhythmias and weakness. Hypoglycemia (C) causes sweating and tremors. Hypocalcemia (D) causes tingling and tetany. Recognizing and escalating care promptly helps prevent seizures or coma.
