A nurse is caring fro a critically ill patient with a urinary retention
catheter, Which hourly urine output should the nurse first alert the
nurse that the primary health-care provider should be notified?
1. 20ml
2.30ml
3.60ml
4.120ml
,2 | Page
Ans: (2). The circulating blood volume purfuses the kidneys producing a
glomerular filtrate to which varying amounts are either reabsorbed or
excreted to maintain fluid balance. When a person's urinary output is only
30ml, it indicates a deficienet circulating fluid volume, inadequate renal
perfusion, and or kidney disease. The HCP should be notified.
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
,3 | Page
Ans: (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.

Ans: (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
