NURS300 Exam 2 Sherpath Questions AndAccurate Answers
Which of the following arterial blood gas values 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 of the following conditions may lead to too many metabolic acids in the patient's
body?
-Excess vomiting
-severe infection
-bacterial pneumonia
-psychological distress - Answer Severe infection
Which of the following symptoms can be a result of respiratory acidosis?
-Headache
-Muscle cramps
-abdominal pain
-numbness and tingling of fingers - Response headache
Which statement identifies a need for further teaching about acid-base balance?
Choose all that apply.
-The normal pH range is 7.35 to 7.45 for arterial blood in adults.
-the acid-base balance can be measured by arterial blood gases.
,-The higher the H+ ion concentration of the body, the more alkaline the body is.
-the elimination of acids from the body shows an abnormality in the body.
- The body maintains a balance between acids and bases for proper functioning of the
cells. - Answer - The more the number of H+ ions in the body, the more alkaline the body.
- It is considered abnormal when acids are being excreted from the body.
Which of the following is associated with severe hyperthyroidism, confusion, tachypnea,
and arterial blood gas pH less than 7.35?
-metabolic acidosis
-metabolic alkalosis
-respiratory acidosis
-respiratory alkalosis - Answer - metabolic acidosis
Which of the following is 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 classified as a transcellular fluid. Fluid outside of the cells is called
extracellular fluid. Fluid outside of the blood vessels is called interstitial fluid.
A healthcare provider orders 2L of IV fluid to be delivered over 6 hours using gravity
flow tubing and a macrodrip with a drop factor of 10 on a patient experiencing 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. In this case,
intravenous fluid flow rate is 2L or 2000 mL for 6 hours and 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
- The respiratory compensation for metabolic alkalosis includes all of the following
except
Increased pH of brain cells
Decreased blood bicarbonate
Decreased cerebrospinal fluid pH
Answer
Decreased cerebrospinal fluid pH
For the patient with chronic diarrhea who demonstrates a positive Chvostek's sign,
which electrolyte imbalance will the nurse suspect?
Hypokalemia
Hypocalcemia
Hyponatremia
Hypomagnesemia
Hypophosphatemia
Answer
hypocalcemia
hypomagnesemia
The patient with which condition would the nurse expect to see associated with
respiratory acidosis?
muscle cramps
abdominal pain
light-headedness
numbness of the fingers
, Answer
light headedness
Which of the following level increases can account for the patient's high anion gap
metabolic acidosis who presents with complaints of extreme exercise the previous day?
-ketoacids
-lactic acids
-unusual organic acids
-normal metabolic acids - Answer lactic acids
Which of the following conditions of a patient is related to respiratory alkalosis?
-anxiety
-acute pain
-chronic bronchitis
-long periods of sobbing
-bacterial pneumonia - Answer -anxiety
-acute pain
-long periods of crying
---------------------------------
Chronic bronchitis, and bacterial pneumonia are related to respiratory acidosis.
Which of the following conditions does the nurse suspect based on a patient's complaint
of light-headedness and tingling of the fingers, along with arterial blood gas laboratory
findings indicating the pH is above 7.45?
-hypercalcemia
-metabolic acidosis
-hypermagnesemia
-respiratory alkalosis - Answer respiratory alkalosis
