CERTIFICATION EVALUATION EXAMS 2026
COMPLETE QUESTIONS ANSWERS
◉ A nurse is caring for a patient that has depended edema. Which
pressure has caused the excess fluid in the interstitial compartment?
1. Oncotic pressure
2. Diffusion pressure
3. Hydrostatic pressure
4. Intraventricular pressure Answer: (3) Hydrostatic pressure is the
pressure exerted by a fluid within a compartment, such as blood within
the vessels. Hydrostatic pressure moves fluid from an area of greater
pressure to an area of lower pressure. Hydrostatic pressure within the
vessels of the body moves fluid from the intravascular compartment into
the interstitial compartment. Interstitial fluid is extracelluar fluid that
surrounds the cells.
◉ A nurse evaluates the pts. fluid balance by monitoring the patient's
intake and output. Which must the nurse understand about the ratio of
the patient's fluid intake to output?
1. Intake should be slightly more than the output.
2. Intake should be higher than the fluid output.
3. Intake should be lower than the urine output.
,4. Intake should be equal to the urine output. Answer: (1) The volume
and the composition of body fluids are kept in a delicate balance by a
harmonious interaction of the kidneys and the endocrine, respiratory,
cardiovascular, integumentary, and gastrointestinal systems.
◉ Hydrochlorothiazise (HCTZ) a diruretic, is prescribed for a patient
who is retaining fluid. The nurse should encourage the pt. to ingest
nutrients that contain which electrolyte?
1. Magnesium
2. Potassium
3. Calcium
4. Sodium Answer: (2) Most diuretics affect the renal mechanisms for
tubular secretion and reabsorption of electrolytes, particularly potassium.
Because of potassium's narrow therapeutic window of 3.5-5.0 mEq/L
and its role in the sodium potassium pump and muscle contraction,
depleted potassium MUST be supplemented by increasing the dietary
intake of foods high in potassium and or potassium drug therapy.
◉ The most common cause of respiratory alkalosis is
1. hyperventilation
2. hypoventilation Answer: hyperventalation
◉ Which should a nurse do to encourage a confused patient to drink
more fluid?
, 1. Serve the fluid that a tepid temperature.
2. Explain the reason for the desired intake.
3. Offer the patient something to drink every hour.
4. Leave a pitcher of water at the patient's bedside. Answer: (3) frequent
smaller volumes of fluid 50 to 100 mL per hour are better tolerated
physiologically and psychologically than in frequent larger volumes of
fluid.
◉ A nurse suspects that an older adult may have a fluid and electrolyte
imbalance. Which assessment best reflects fluid and electrolyte balance
in an older adult?
I. intake and output results
2. Serum laboratory values
3. Condition of the skin
4. Presence of tenting Answer: (2) Laboratory studies provide objective
measurements of indicators of fluid, electrolytes, and acid-base balance.
Common diagnostic test include serum blood studies of electrolytes
osmolarity, hemoglobin, hematocrit, and arterial blood gases
◉ A patient has continuous bladder irrigation. Which of the nurse do
with the irrigant when calculating the fluid balance for this patient?
