1. When assessing a patient with hypotonic fluid volume excess (FVE) the nurse can
expect to find:
a. Hyponatremia
b. Confusion
c. Headache
d. All of the above - ANSWER-D all of the above
Rationale_Na+ decreases with FVE, confusion may result from cerebral swelling as well
as headache for the same reason.
2. The nurse evaluates that discharge teaching has been effective when the patient with
hypocalcemia states:
a. "I shouldn't take antacids such as TUMS."
b. "I should notify my healthcare provider if I start to feel tingling or numbness around
my mouth."
c. "I'll need to cut down on my protein in my diet."
d. "I will watch my urine for signs of kidney stones." - ANSWER-B I should notify my
healthcare provider if I start to feel tingling or numbness around my mouth
Rationale_Circumoral paresthesia is a sign of impending tetany (intermittent and
involuntary muscle spasms caused by low Ca+) and should alert the patient to contact
the physician.
3. A 28 year old patient is admitted with severe bleeding from a fractured femur. Which
intravenous fluid does the nurse anticipate would be ordered as the most appropriate to
replace that fluid loss?
a. Normal Saline
b. 3% saline
c. 5% dextrose in water
d. 5% dextrose in 0.225 saline - ANSWER-A Normal Saline
Rationale NS is an isotonic fluid and is appropriate for fluid (blood) loss
4. When caring for a patient at risk for fluid overload the nurse notices that overnight the
patient gained 6 pounds. The nurse interprets this as:
a. A 3L fluid gain
b. Impending renal failure
c. Excessive diuresis

5. You are working in the ER of a local hospital. A patient comes in "feeling ill". The
doctor orders electrolytes on the patient and finds that the Na+ is 135, the K+ is 2.7,
chloride is 95 and C02 is 26. You would expect the doctor to order:
a. Na+ supplements IV
b. K+ supplements PO
c. Na+ supplements PO
d. Chloride PO - ANSWER-B K+ supplements PO

and safest method of replacement.
6. The skin turgor assessment of a patient with hypernatremia as a result of
extracellular fluid loss would show:
a. No skin "tenting"
b. Prolonged skin "tenting"
c. Prolonged pitting edema
d. Widespread non-pitting edema - ANSWER-B Prolonged skin "tenting"
Rationale_Poor skin turgor is a measure of tissue hydration, fluid loss has less elasticity
of the skin. Edema is not present in fluid loss but in fluid overload.
7. Marathon runners are at risk for fluid volume deficit. Which of the following is a
related factor?
a. Decreased diuresis
b. Disease related processes
c. Decreased breathing and perspiration
d. Increased breathing and perspiration - ANSWER-D Increased breathing and
perspiration
Rationale_Fluid losses increase through increased respirations and increased
perspiration from heavy physical activity.
8. During shift report, you are told that your patient has a positive Chvostek's sign. You
would expect his lab values to reveal:
a. Total serum calcium level below 8.5 mEq/L
b. Total serum calcium level above 10.1 mEq/L
c. Normal serum calcium level - ANSWER-A Total serum calcium level below 8.5 mEq/L
Rationale_Chevostek's sign is associated with hypocalcemia and is a hyperexcitability
of the facial nerve when stimulated in front of the earlobe.

9. In addition to its responsibility for fluid balance sodium is also responsible for:
a. Good eyesight and vitamin balance

diuretic therapy. The nurse suggests that she increase her dietary intake of potassium.
Which foods should she consume?
a. Chocolate, mushrooms, and bananas
b. Canned soups, peas and mild
c. Apples, whole wheat bread, and oatmeal
d. Dairy products and whole grains - ANSWER-A Chocolate, mushrooms, and bananas
Rationale These items have higher K+ than the other food choices.

Compared to an infant, the patient's body contains how much water by weight?
a. More
b. Less
c. The same
d. Impossible to say - ANSWER-B less
Rationale_60% total body weight in adult, 70-80% total body weight in an infant.
12. Isotonic fluid volume deficit can result from:
a. Insensible water loss during prolonged fever
b. Inadequate ingestion of fluids and electrolytes
c. Impaired thirst regulation
d. All of the above - ANSWER-D all of the above
Rationale_All will impair the intake or loss of fluid, potentially electrolytes also
13. Dietary recommendations for a patient with hypotonic fluid excess should include:
a. Decreased sodium intake
b. Increased sodium intake
c. Increased fluid intake
d. Intake of potassium rich foods - ANSWER-B increased sodium intake
Rationale_Because this may indicate a Na+ loss or a water gain.
