NMNC 1210 Exam 1 Fluid and
Electrolytes8
The nurse reviews a clients record and determines that the client is at risk for developing a
potassium deficit if which situation is documented?
1. Sustained tissue damage
2. Requires nasogastric suction
3. Has a history of Addison's disease
4. Uric acid level of 9.4 mg/dL - ANSWERS2. Requires nasogastric suction
The nurse is caring for a client with heart failure. On assessment, the nurse notes that the client
is dyspneic, and crackles are audible on auscultation. What additional manifestations would the
nurse expect to note in this client if excel fluid volume is present?
1. Weight loss and dry skin
2. Flat neck and hand veins and decreased urinary output
3. An increase in blood pressure and increased respirations
4. Weakness and decreased central venous pressure (CVP) - ANSWERS3. An increase in bp and
increase respirations
The nurse reviews a client's electrolyte laboratory report and notes that the potassium level is
2.5 mEq/L. Which patterns should the nurse watch for on the ECG as a result of the laboratory
value? Select all that apply
1. U waves
, 2. Absent P waves
3. Inverted T waves
4. Depressed ST segment
5. Widened QRS complex - ANSWERS1, 3, 4
1. U waves
3. Inverted T waves
4. Depressed ST segment
Rationale: absent P waves are not a characteristic of hypokalemia but may be noted in a client
with a fib. A widened QRS complex may be noted in hyperkalemia and hypermagnesemia
A serum potassium level lower than 3.5 mEq/L indicates? - ANSWERShypokalemia
Absent P waves are a characteristic of? - ANSWERSAtrial fibrillation (A fib)
Potassium chloride intravenously is prescribed for a client with heart failure experiencing
hypokalemia. Which actions should the nurse take to plan for preparation and administration of
the potassium?
Select all that apply
1. Obtain an IV infusion pump
2. Monitor urine output during administration
3. Prepare the medication for bolus administration
4. Monitor the IV site for signs of infiltration of phlebitis
5. Ensure that the medication is diluted in the appropriate volume of fluid
