100% Verified Answers.
Which arterial blood gas value is abnormal?
-pH 7.35
-partial pressure of oxygen (PaO2) 75mm HG
-Partial pressure of carbon dioxide (PaCO2) 42 mm hg
-Oxygen saturation 95.2% - answer✔Partial pressure of oxygen (PaO2) 75 mm Hg
Which condition may result in excessive metabolic acids in the body of the patient?
-Excess vomiting
-severe infection
-bacterial pneumonia
-psychological distress - answer✔Severe infection
Which symptom is caused by respiratory acidosis?
-Headache
-Muscle cramps
-abdominal pain
-numbness and tingling of fingers - answer✔headache
Which statement indicates a need for further teaching regarding acid-base balance?Select all.
-The normal range of pH is 7.35 to 7.45 for arterial blood in adults.
-the acid-base balance can be monitored via arterial blood gases.
-The higher the H+ ion count in the body, the more alkaline the body is.
-The excretion of acids from the body indicates an abnormality in the body.
-The body maintains a balance between acids and bases for proper cell functioning. - answer✔-
The higher the H+ ion count in the body, the more alkaline the body is.
-The excretion of acids from the body indicates an abnormality in the body.
Which condition is characterized by severe hyperthyroidism, confusion, increased respiratory
rate, and a pH of arterial blood gas below 7.35?
-metabolic acidosis
-metabolic alkalosis
-respiratory acidosis
-respiratory alkalosis - answer✔-metabolic acidosis
Which fluid is considered an intravascular fluid?
-synovial fluid
-plasma of the blood
-fluid outside the cells
-fluid outside the blood vessels - answer✔-plasma of the blood
________________________________________
synovial fluid is considered a transcellular fluid. Extracellular fluid is located outside the cells.
Interstitial fluid is located outside the blood vessels.
A health care provider prescribes 2 L of intravenous fluid over 6 hours using gravity-flow tubing
and a macrodrip with a drop factor of 10 for a patient who has been vomiting. Calculate the
minute flow rate of the infusion in gtt/min.Round to nearest whole number. - answer✔56
-------------------------------
the minute flow rate is calculated as (mL/hr)(drop factor/60 mins)=gtt/min. The flow rate of the
intravenous fluid is 2L or 2000 mL for 6 hours, and the srop factor is 10. Therefore the minute
flow rate is : (2000/6)(10/60)=55.56. Rounds up to 56
Which clinical condition will the nurse assess for in the patient complaining of frequent
headaches and dysrhythmia whose laboratory reports reveal respiratory acidosis?
-increased blood pH
-increased pH of brain cells
-decreased blood bicarbonate
-decreased cerebrospinal fluid pH - answer✔-decreased cerebrospinal fluid pH
Which electrolyte imbalance will the nurse suspect in the patient with chronic diarrhea who
demonstrates a positive Chvostek's sign? Select all.
- Hypokalemia
-Hypocalcemia
-Hyponatremia
-Hypomagnesemia
-Hypophosphatemia - answer✔-hypocalcemia
-hypomagnesemia
Which patient condition would the nurse anticipate seeing with respiratory acidosis?
-muscle cramps
-abdominal pain
-light-headedness
-numbness of the fingers - answer✔-light headedness
Which level increase may be responsible for the presence of metabolic acidosis with a high anion
gap in a patient reporting extreme exercise the day before?
-ketoacids
-lactic acids
-unusual organic acids
-normal metabolic acids - answer✔lactic acids
Which patient condition is associated with respiratory alkalosis?
-anxiety
-acute pain
-chronic bronchitis
-long periods of sobbing
-long periods of crying
---------------------------------
Chronic bronchitis, and bacterial pneumonia are associated with respiratory acidosis.
Which condition will the nurse suspect when the patient reports light-headedness and tingling of
the fingers and arterial blood gas laboratory findings show the pH to be above 7.45?
-hypercalcemia
-metabolic acidosis
-hypermagnesemia
-respiratory alkalosis - answer✔respiratory alkalosis
Which condition will the nurse suspect the health care provider to diagnose in a patient with a
head injury whose sodium level is 109mEq/L?
-diabetes insipidus
-fatal cardiac dysrhythmias
-type B chronic obstructive pulmonary disease
-syndrome of inappropriate antidiuretic hormone - answer✔syndrome of inappropriate
antidiuretic hormone
Which process that moves water and electrolytes between body compartments is impacted as a
result of a mastectomy with the removal of lymph nodes?
-osmosis
-diffusion
-filtration
-active transport - answer✔-filtration
which statement indicates a need for additional instruction regarding the process that move water
and electrolytes between body compartments?
-"filtration is the process that moves fluid into and out of the capillaries."
-"osmosis allows the free movement of potassium across cell membranes."
-"active transport uses adenosine triphosphate (ATP) to move electrolytes against the
concentration gradient."
