|FULL REVISED CCTC NATCO REAL EXAM
1. A 45-year-old male is pronounced brain dead following a traumatic brain injury.
During the apnea test, the patient's PaCO2 rises to 65 mmHg with no respiratory
effort. What is the most appropriate next step?
A. Repeat the apnea test in 30 minutes
B. Administer sodium bicarbonate
C. Declare brain death — CORRECT ANSWER
D. Obtain a confirmatory cerebral angiogram
RATIONALE: A positive apnea test is defined as a PaCO2 ≥ 60 mmHg (or a 20
mmHg increase from a normal baseline) without any respiratory effort. This
confirms the absence of a respiratory drive, completing the clinical brain death
examination. Ancillary testing is unnecessary for a complete and valid clinical
exam.
2. Which of the following is an absolute contraindication to the apnea test?
A. Core temperature of 35.5°C (95.9°F)
B. Systolic blood pressure of 100 mmHg
C. Baseline PaCO2 of 38 mmHg
D. All of the above — CORRECT ANSWER
,RATIONALE: The apnea test requires specific conditions to be valid. These
include a core temperature ≥ 36°C, a systolic BP ≥ 90 mmHg, euvolemia, and a
baseline PaCO2 between 35-45 mmHg. If any of these conditions are not met, the
test is contraindicated and considered unsafe.
3. Which ancillary test is considered the gold standard for confirming brain death
when the clinical exam or apnea test cannot be completed?
A. Electroencephalogram (EEG)
B. Transcranial Doppler (TCD)
C. Four-vessel cerebral angiography
D. Nuclear medicine cerebral blood flow scan — CORRECT ANSWER
RATIONALE: The radionuclide cerebral blood flow scan is the most widely
accepted ancillary test. It demonstrates the absence of intracranial blood flow,
often showing a "hollow skull" sign. While four-vessel angiography is the
historical gold standard, it is more invasive and less commonly used in practice
than the nuclear scan.
4. A brain-dead donor develops a urine output of 400 mL/hr with a urine
osmolality of 150 mOsm/kg and a serum sodium of 155 mEq/L. Which treatment
is most appropriate?
A. Administer a fluid bolus of normal saline
B. Administer Desmopressin (DDAVP) — CORRECT ANSWER
C. Start an insulin drip
D. Administer methylprednisolone
RATIONALE: The presentation is classic for diabetes insipidus (DI) secondary to
posterior pituitary failure following brain death. The donor is excreting large
volumes of dilute urine, leading to hypernatremia. Desmopressin (a vasopressin
,analog) is the treatment of choice to concentrate the urine and correct the
electrolyte imbalance.
5. What is the target urine output for a brain-dead organ donor?
A. 0.5 - 1 mL/kg/hr
B. 1 - 3 mL/kg/hr — CORRECT ANSWER
C. 3 - 5 mL/kg/hr
D. > 5 mL/kg/hr
RATIONALE: The goal of donor management is to maintain adequate organ
perfusion without causing fluid overload. A urine output of 1-3 mL/kg/hr is the
target. Output below this indicates poor perfusion (pre-renal), while output above
this is often pathological (e.g., DI).
6. Which vasopressor is considered first-line for managing hypotension in a brain-
dead donor due to its ability to address a deficient hormone?
A. Norepinephrine
B. Epinephrine
C. Vasopressin — CORRECT ANSWER
D. Dobutamine
RATIONALE: In brain death, the posterior pituitary fails, leading to a deficiency
in vasopressin (ADH). Vasopressin acts as a potent vasopressor, increasing
systemic vascular resistance (SVR) and blood pressure, while simultaneously
replacing the missing hormone.
7. Which of the following would be an absolute contraindication to organ
donation?
, A. Hepatitis C infection
B. Diabetes insipidus
C. Active rabies infection — CORRECT ANSWER
D. Asymptomatic bacteriuria
RATIONALE: Rabies is an absolute contraindication to organ donation due to the
near 100% mortality rate in immunocompromised recipients. Hepatitis C can be
transmitted to recipients, but donation from HCV-positive donors to HCV-positive
recipients or under specific research protocols is now a common practice.
8. A donor is found to have a positive Nucleic Acid Test (NAT) for HIV. What is
the most appropriate course of action?
A. Proceed with organ recovery, but inform the recipient
B. Discard only the liver and heart
C. Proceed with recovery if the recipient is HIV-positive and meets specific criteria
— CORRECT ANSWER
D. Automatically decline the donor for all organs
RATIONALE: The HOPE Act allows for the transplantation of organs from HIV-
positive donors to HIV-positive recipients with confirmed HIV infection. This is
legal in the US under specific protocols and guidelines.
9. The "hormonal resuscitation" cocktail for a brain-dead donor typically includes
all of the following EXCEPT:
A. Vasopressin
B. Methylprednisolone
C. Levothyroxine (T4)
D. Glucagon — CORRECT ANSWER
