  Which fluids are considered to be isotonic and appropriate in the treatment of fluid loss due to a surgical procedure?
  1. 5 dextrose in lactated ringers
  2. 0.9 sodium chloride (NS)
  3. 0.45 sodium chloride
  4. Lactated Ringers
  5. 5 dextrose in water

Question 2

The nurse is caring for a group of patients on a medical-surgical unit. For which patients would the nurse anticipate the need for intravenous fluid therapy to correct fluid depletion?
 
  1. A patient suffering from constipation

Answer to Question 1

Correct Answer: 2,4,5
Rationale: This is a hypertonic solution and is not appropriate for the treatment of fluid loss due to a surgical procedure.

Answer to Question 2

Correct Answer: 2,3,5
Rationale 1: A patient who is suffering from constipation will not need intravenous fluid due to fluid depletion. A patient with diarrhea may require intravenous fluid due to fluid depletion.
Rationale 2: A patient exhibiting nausea and vomiting may require intravenous fluid to avoid dehydration.
Rationale 3: A patient with a severe burn will often require intravenous fluid due to fluid depletion that occurs from fluid shifts.
Rationale 4: A patient with congestive heart failure retains fluid and will be on fluid restrictions.
Rationale 5: A patient with uncontrolled diabetic ketoacidosis often requires intravenous fluid administration for fluid depletion.
