A seasoned nurse is caring for a patient receiving intravenous fluid therapy for dehydration. The nurse knows that the osmolarity or tonicity of a fluid causes water to move to a different compartment.

The nurse is caring for a patient who weighs 40 kg. The osmolality of the body fluids for this patient is between 11,000 and _____ milliosmoles.
What will be an ideal response?

Question 2

Buffers are chemicals that help maintain normal body Ph. The two primary buffers in the body are

1. sodium and calcium ions.
2. sodium and bicarbonate ions.
3. bicarbonate and phosphate ions.

Answer to Question 1

Correct Answer: 11,800
Rationale : The normal osmolality of body fluids ranges from 275 to 295 milliosmoles per kilogram (mOsm/kg).

Answer to Question 2

Correct Answer: 3
Rationale 1: Sodium and calcium are not buffers.
Rationale 2: Sodium is not a buffer in maintaining normal body Ph.
Rationale 3: Bicarbonate and phosphate are the two primary buffers of Ph balances.
Rationale 4: Potassium and phosphate are not the two primary buffers.
