DOMAIN 1: PATIENT CARE AND ASSESSMENT (Questions 1-75)
Q1: During the pre-treatment assessment, a patient's pre-dialysis weight is 82.5 kg and
their established dry weight is 79.2 kg. What is the approximate fluid volume to be
removed if the patient will have no oral intake during the 4-hour treatment?
A. 2.3 L
B. 3.3 L
C. 4.3 L
D. 5.3 L
Correct Answer: B. [CORRECT]
,Rationale: The fluid volume to be removed is calculated as pre-dialysis weight minus dry
weight: 82.5 kg - 79.2 kg = 3.3 kg. In hemodialysis, 1 kg of weight gain equals
approximately 1 liter of fluid. Therefore, 3.3 L needs to be removed. Option A (2.3 L)
represents an incorrect calculation (subtraction error). Option C (4.3 L) and D (5.3 L) are
miscalculations that would result in over-ultrafiltration and potential hypotension. This
calculation is essential for setting the ultrafiltration goal and assessing fluid
management.
Q2: A patient complains of muscle cramps during the last hour of dialysis. Which of the
following is the MOST appropriate initial nursing intervention?
A. Decrease the ultrafiltration rate
B. Administer hypertonic saline as ordered
C. Slow the blood flow rate
D. Apply warm compresses to the affected area
Correct Answer: A. [CORRECT]
Rationale: Muscle cramps during dialysis are often caused by rapid fluid removal and
hypovolemia. Decreasing the ultrafiltration rate addresses the underlying cause by
reducing the rate of fluid removal. While administering hypertonic saline (B) may help, it
is not the initial intervention and requires a physician order. Slowing blood flow rate (C)
does not directly address cramping and may compromise dialysis adequacy. Warm
,compresses (D) provide symptomatic relief but do not correct the cause. The priority is
to modify the factor causing the cramps—excessive ultrafiltration. According to KDOQI
guidelines, cramps affect 20-50% of dialysis patients and are best managed by
adjusting UF rates.
Q3: Which of the following laboratory values is MOST indicative of adequate dialysis
adequacy when using the Kt/V measurement?
A. Kt/V greater than 0.8
B. Kt/V greater than 1.2
C. Kt/V greater than 1.4
D. Kt/V greater than 2.0
Correct Answer: B. [CORRECT]
Rationale: The minimum adequate Kt/V according to CMS and NKF-KDOQI guidelines is
1.2 for adult hemodialysis patients (single pool Kt/V). A Kt/V of 1.2 indicates that the
delivered dose of dialysis is sufficient. Option A (0.8) is below the minimum standard
and indicates inadequate dialysis. Option C (1.4) and D (2.0) are above the minimum
and may be acceptable or even desirable in some patients, but 1.2 is the established
minimum threshold for adequacy. Kt/V measures urea clearance as a surrogate for
small solute removal. CMS requires Kt/V ≥ 1.2 for reimbursement compliance.
, Q4: A patient's pre-dialysis blood pressure is 186/112 mmHg. Which action should the
technician take FIRST?
A. Proceed with dialysis and monitor closely
B. Notify the nurse immediately
C. Administer prescribed antihypertensive medication
D. Reschedule the dialysis treatment
Correct Answer: B. [CORRECT]
Rationale: A blood pressure of 186/112 mmHg represents a hypertensive emergency
(Stage 2 hypertension with systolic >180 or diastolic >120). The technician must notify
the nurse immediately for evaluation and potential intervention. While the patient may
still receive dialysis, the nurse needs to assess for symptoms of hypertensive
emergency (headache, chest pain, shortness of breath, neurological changes) and
determine if treatment is needed before or during dialysis. Technicians cannot
administer medications (C) without nurse supervision. Rescheduling (D) is a medical
decision made by the nurse or physician, not the technician.
Q5: The primary purpose of administering heparin during hemodialysis is to:
