Exam 2026/2027 Actual Questions | Verified
Answers | NGN | Detailed Rationales | Grade A
1. A patient presents to the clinic with suspected carbon monoxide
poisoning, O2 saturation is 99%. The NP understands that:
A. The patient does not have carbon monoxide poisoning
B. Carbon monoxide has already flushed out of the body
C. The patient needs supplemental oxygen
D. The patient should be prepared for hyperbaric oxygen therapy
Correct Answer: C. The patient needs supplemental oxygen
Rationale:
1. Pulse oximetry cannot distinguish between oxyhemoglobin and
carboxyhemoglobin, so SpO2 can be normal even with severe CO poisoning.
2. Supplemental oxygen accelerates the elimination of carbon monoxide.
3. This is a standard emergency medicine question.
2. H2O molecules move from intracellular fluid compartment to
extracellular fluid compartment by way of:
A. Diffusion
B. Osmosis
,2|Page
C. Hydrostatic force
D. Plasma oncotic pressure
Correct Answer: B. Osmosis
Rationale:
1. Osmosis is the movement of water across a semipermeable membrane from an
area of low solute concentration to high solute concentration.
2. This is a basic physiology question.
3. The body retains bicarbonate to maintain the anion balance during
vomiting and can cause:
A. Respiratory acidosis
B. Respiratory alkalosis
C. Metabolic acidosis
D. Metabolic alkalosis
Correct Answer: D. Metabolic alkalosis
Rationale:
1. Loss of gastric acid (HCl) through vomiting causes retention of bicarbonate,
leading to metabolic alkalosis.
2. This is a standard acid-base disorder question.
4. A geriatric pregnancy patient asks what the amniocentesis will show
that confirms that the baby has a neural tube defect:
A. Embryonic proteins
B. Alpha fetoprotein
C. Trisomy 21 deletions
D. DNA polymerase
, 3|Page
Correct Answer: B. Alpha fetoprotein
Rationale:
1. Elevated alpha-fetoprotein (AFP) in amniotic fluid indicates neural tube
defects (spina bifida, anencephaly).
2. This is a standard obstetrics question.
5. Which findings are consistent with trisomy 21 syndrome?
A. IQ higher than 70
B. High set nasal bridge
C. Protruding tongue
D. Flat, high-set ears
Correct Answer: C. Protruding tongue
Rationale:
1. Down syndrome (Trisomy 21) is associated with protruding tongue, low-
set ears, low nasal bridge, and intellectual disability (IQ typically below 70).
2. This is a standard genetics question.
6. Housekeeping cells are responsible for:
A. Eliminating cancer cells
B. Ridding the body of toxins
C. Deactivating oncogenes
D. Maintenance of all cells
Correct Answer: D. Maintenance of all cells
Rationale:
1. Housekeeping genes and cells maintain basic cellular functions.
2. This is a basic cell biology question.
