FCCN LEVEL 1 PRACTICE TEST 2026
TESTED QUESTIONS AND CORRECT
ANSWERS

◉ hypophosphatemia
Answer: - cause by hyperparathyroidism, chronic diarrhea, long
term diuretic use, malnutrition and severe burns


- muscle weakness
- impaired cardiac function
- poor tissue oxygenation
- failure to wean from mechanical ventilation
- depressed CNS - confusion


◉ treating low phosphorus
Answer: - increase intake of phos rich food
- IV
- assess for hypercalcemia
- consider Mg replacement simultaneously


◉ hyperphosphatemia

,Answer: - this is rare except for people with severe kidney
dysfunction


- stroke
- heart attack
- poor circulation
- calcium combines with phosphate to form crystals that calcify on
walls of vessels and heart
- crystals can form on skin too causing severe itching


◉ order for electrolyte replacement therapy
Answer: 1. Mg
2. K
3. phosphorus
4. Ca


◉ physical assessment of perfusion
Answer: - pulses
- blood pressure
- skin
- kidneys
- sensorium

, ◉ oxygenation
Answer: - SPO2
- nasal cannula and oxygen mask help oxygenate


◉ ventilation
Answer: - how fast and deep pt is breathing
- look at CO2 on ABG to assess ventilation
- BiPAP, Ambu bagsm and ventilators help ventilate


*patient can have good oxygenation but not be ventilating
adequately


◉ systolic Blood Pressure
Answer: - pressure on arterial walls during ventricular contraction
- increase in CO/force of contraction with exercise will increase SBP
but not necessarily affect DBP


◉ diastolic BP
Answer: - pressure during ventricular relaxation
- vasomotor tone of arterioles and venules
