DOMAIN 1: PATIENT CARE AND ASSESSMENT (15 Questions)
Q1: A patient with end-stage renal disease (ESRD) arrives for dialysis with a blood
pressure of 188/110 mmHg, 2+ pitting edema in lower extremities, and reports
shortness of breath. Which assessment finding requires immediate intervention before
initiating dialysis?
A. Elevated blood pressure only
B. 2+ pitting edema
C. Shortness of breath with potential fluid overload/pulmonary edema [CORRECT]
D. All findings are expected in ESRD and require no immediate action
Correct Answer: C
Rationale: While all findings indicate fluid overload, shortness of breath (dyspnea)
suggests potential pulmonary edema, a life-threatening condition requiring immediate
evaluation. The technician must notify the nurse immediately and be prepared for
emergency interventions (oxygen, possible urgent dialysis with caution, or transfer to ED
if severe). Option A (elevated BP) is common but not immediately life-threatening in this
context. Option B (edema) is chronic finding. Option D is dangerous—technicians must
recognize red flags requiring immediate escalation. CMS Conditions for Coverage
require assessment of patients before each treatment.
,Q2: Which laboratory value best indicates adequate dialysis delivery and is the primary
measure for dialysis adequacy?
A. Serum creatinine alone
B. Blood urea nitrogen (BUN) pre-dialysis only
C. Kt/V (K × t / V) or Urea Reduction Ratio (URR) [CORRECT]
D. Hemoglobin level
Correct Answer: C
Rationale: Kt/V and URR are the standardized measures of dialysis adequacy. Kt/V ≥ 1.2
(single pool) or URR ≥ 65% indicates adequate urea clearance. Kt/V incorporates
dialyzer clearance (K), treatment time (t), and urea distribution volume (V). Option A
(creatinine) reflects muscle mass and filtration but doesn't measure dialysis dose.
Option B (BUN alone) doesn't account for treatment efficiency. Option D (hemoglobin)
reflects anemia management, not dialysis adequacy. CMS requires monthly adequacy
monitoring.
Q3: A patient's pre-dialysis assessment reveals the following: temperature 37.2°C, pulse
88 bpm regular, respirations 18, blood pressure 164/98 mmHg, weight 3.2 kg above dry
weight. Which parameter indicates the patient's "dry weight" has been exceeded?
A. Temperature 37.2°C
B. Pulse 88 bpm
C. Blood pressure 164/98 mmHg
D. Weight 3.2 kg above dry weight [CORRECT]
Correct Answer: D
Rationale: Dry weight (target weight or euvolemic weight) is the post-dialysis weight at
which the patient has minimal edema, normal blood pressure without antihypertensives,
and no orthostatic symptoms. The 3.2 kg (3.2 L) excess represents interdialytic fluid
gain. While elevated BP (C) often accompanies fluid overload, it can have other causes.
Temperature (A) and pulse (B) are not direct indicators of volume status. Technicians
must accurately measure and document weights to guide ultrafiltration goals.
,Q4: Which medication is most commonly administered intravenously during
hemodialysis to prevent clotting in the extracorporeal circuit?
A. Warfarin (Coumadin)
B. Aspirin
C. Heparin [CORRECT]
D. Clopidogrel (Plavix)
Correct Answer: C
Rationale: Heparin is the standard anticoagulant for hemodialysis, administered as a
bolus (typically 1000-5000 units) followed by continuous infusion or intermittent dosing
to maintain circuit patency. It acts immediately and is partially removed by dialysis.
Warfarin (A) is oral, has delayed onset, and long half-life—inappropriate for acute
dialysis anticoagulation. Aspirin (B) and clopidogrel (D) are antiplatelet agents for
long-term cardiovascular protection, not circuit anticoagulation. Heparin-free dialysis is
used for patients with heparin-induced thrombocytopenia (HIT) or active bleeding.
Q5: A patient complains of severe muscle cramping in the legs during the last hour of
dialysis. The blood pressure is 94/60 mmHg, down from pre-dialysis 156/88 mmHg.
What is the most likely cause?
A. Excessive ultrafiltration rate causing hypovolemia [CORRECT]
B. Heparin overdose
C. Dialysate sodium too high
D. Air embolism
Correct Answer: A
Rationale: Intradialytic hypotension with muscle cramping is classic for excessive
ultrafiltration (fluid removal) exceeding vascular refilling capacity. The 62 mmHg
systolic drop indicates significant hypovolemia. Interventions: reduce or stop
ultrafiltration, place patient in Trendelenburg position, administer normal saline
(100-250 mL). Heparin overdose (B) causes bleeding, not cramping. High dialysate
, sodium (C) would cause thirst and hypertension. Air embolism (D) presents with chest
pain, dyspnea, neurological symptoms—medical emergency.
Q6: Which laboratory finding would indicate a need to increase the patient's EPO
(erythropoietin) dose?
A. Hemoglobin 11.5 g/dL, TSAT 25%
B. Hemoglobin 9.2 g/dL, ferritin 150 ng/mL [CORRECT]
C. Hemoglobin 13.8 g/dL, ferritin 800 ng/mL
D. Hemoglobin 10.8 g/dL with blood pressure 140/90 mmHg
Correct Answer: B
Rationale: KDOQI and CMS guidelines target hemoglobin 10-12 g/dL in ESRD patients.
Hemoglobin 9.2 g/dL is below target, indicating inadequate EPO response if iron stores
are adequate (ferritin 150 ng/mL is sufficient, TSAT not provided but likely adequate).
Option A is at target. Option C exceeds upper limit (13.5 g/dL) and has iron
overload—reduce EPO. Option D is near target; hypertension is not indication to adjust
EPO. Always assess iron status (ferritin ≥100 ng/mL, TSAT ≥20%) before adjusting
EPO—functional iron deficiency prevents EPO response.
Q7: A patient with CKD Stage 5 has the following labs: potassium 5.8 mEq/L,
phosphorus 6.2 mg/dL, calcium 8.4 mg/dL, PTH 450 pg/mL. Which medication should
the technician ensure the patient receives with meals?
A. Calcitriol (active vitamin D)
B. Sevelamer (phosphate binder) [CORRECT]
C. Epoetin alfa
D. Cinacalcet
Correct Answer: B
Rationale: Elevated phosphorus (6.2 mg/dL, normal 2.5-4.5) and elevated PTH indicate
secondary hyperparathyroidism from CKD-mineral and bone disorder (CKD-MBD).
Phosphate binders (calcium acetate, sevelamer, lanthanum) must be taken with meals
