CNF EXAM 2: FLUID, ELECTROLYTE,
ACID-BASE BALANCE (39)
QUESTIONS WITH CORRECT
ANSWERS [GRADED A+]
A nurse needs to get an accurate fluid output assessment of a client with
severe diarrhea. Which action should the nurse perform?
- Weigh the volume of IV fluid before instilling.
- Weigh the client's wet linen or dressing.
- Weigh the client without soiled incontinence pads.
- Weigh the client before and after meals - ✔✔Weigh the client's wet linen
or dressing.
In cases in which accurate assessment is critical to a client's treatment, the
nurse weighs wet linens, pads, or dressings and subtracts the weight of a
similar dry item. The nurse does not weigh the client without soiled

,incontinence pads. The nurse does not weigh the client before and after
meals to obtain an accurate assessment of the fluid output.
A home care nurse is teaching a client and family about the importance of a
balanced diet. The nurse determines that the education was successful
when the client identifies which of the following as a rich source of
potassium?
- Dairy products
- Apricots
- Processed meat
- Bread products - ✔✔Apricots
Apricots are a rich source of potassium. Dairy products are rich sources of
calcium. Processed meat and bread products provide sodium.
An intravenous hypertonic solution containing dextrose, proteins, vitamins,
and minerals is known as:
- cellular hydration.

,- volume expander.
- total parenteral nutrition.
- blood transfusion therapy. - ✔✔total parenteral nutrition.
Total parenteral nutrition is a hypertonic solution containing 20% to 50%
dextrose, proteins, vitamins, and minerals that is administered into the
venous system.
A decrease in arterial blood pressure will result in the release of:
- protein.
- thrombus.
- renin.
- insulin. - ✔✔renin.
Decreased arterial blood pressure, decreased renal blood flow, increased
sympathetic nerve activity, and/or low-salt diet can stimulate renin release.

, A 50-year-old client with hypertension is being treated with a diuretic. The
client reports muscle weakness and falls easily. The nurse should assess
which electrolyte?
- Sodium
- Chloride
- Phosphorous
- Potassium - ✔✔Potassium
Diuretics, commonly given to treat high blood pressure and heart failure,
can cause an extracellular deficit or loss of electrolytes including
potassium, calcium, and magnesium.
A physician orders an infusion of 250 mL of NS in 100 minutes. The set is
20 gtt/mL. What is the flow rate?
- 20 gtt/min
- 30 gtt/min
- 40 gtt/min
- 50 gtt/min - ✔✔50 gtt/min
