Free CCHT Exam Questions That Helps Candidates Pass

CCHTs practice under defined scope and supervision. Medication administration and dosage titration (including systemic anticoagulation) are nursing responsibilities that require assessment, orders, and documentation. When clotting is suspected, the technician’s role is to recognize signs (darkening venous blood, rising pressures, fibrin in chambers), ensure correct heparin line setup, verify lines are not kinked, and promptly notify the RN. The RN evaluates the patient and circuit, confirms the need for anticoagulation changes, and implements per standing orders or provider directives. Independently adjusting heparin (option B) exceeds scope and jeopardizes patient safety and compliance. Delegating to another tech (C) does not correct the scope issue. Directly obtaining and acting on a medication order (D) without RN involvement is inappropriate. The CCHT supports by stabilizing the circuit (e.g., gentle saline flushes if within policy), documenting findings, and communicating changes. Clear role boundaries protect patients and staff by ensuring assessments and medication decisions are performed by licensed professionals.

The UF control regulates how much fluid is removed from the patient, based on prescribed goals. It does not directly alter sodium (B), blood pressure (C), or clotting (D). Correct UF ensures balance between fluid removal and hemodynamic stability.

Excess fluid overload requires higher ultrafiltration rates, which can trigger hypotension, cramps, nausea, and headaches. Hypertension (B) is also common but less acute than hypotension during aggressive UF. Hypoglycemia (C) and hypothermia (D) are unrelated. Patient education on fluid restriction is key.

Arterial alarms protect against access collapse, air aspiration, or clotting. The technician must identify root cause (needle placement, kinks, clotting) and correct. Disabling alarms (B) is unsafe. Adjusting UF (C) is unrelated. Ignoring alarms (D) risks harm. Continuous safe monitoring is essential.

Explanation (150–250 words):

Dialysis disequilibrium syndrome (DDS) results from rapid solute removal in new or severely uremic patients. Symptoms include headache, nausea, confusion, restlessness, and sometimes seizures. The technician should notify the RN immediately, slow dialysis if ordered, and provide supportive care. Hypoglycemia (B) presents with sweating and tremors. Air embolism (C) causes acute chest pain and dyspnea. Hemolysis (D) presents with chest/back pain and red blood. Preventing DDS involves gradual dialysis initiation.
