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 intravenous (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 or phlebitis.
5. Ensure that the medication is diluted in the appropriate volume
of fluid.
6. Ensure that the bag is labeled so that it reads the volume of
potassium in the solution. -

Potassium chloride administered intravenously must always be
diluted in IV fluid and infused via an infusion pump. Potassium
chloride is never given by bolus (IV push). Giving potassium chloride
by IV push can result in cardiac arrest. The nurse should ensure that
the potassium is diluted in the appropriate amount of diluent or
fluid. The IV bag containing the potassium chloride should always
be labeled with the volume of potassium it contains. The IV site is
monitored closely, because potassium chloride is irritating to the
veins and there is risk of phlebitis. In addition, the nurse should
monitor for infiltration. The nurse monitors urinary output during
administration and contacts the primary health care provider if the
urinary output is less than 30 mL/hr.
The nurse is assessing a client with a lactose intolerance disorder
for a suspected diagnosis of hypocalcemia. Which clinical
manifestation would the nurse expect to note in the client?
1. Twitching
2. Hypoactive bowel sounds

3. Negative Trousseau's sign
4. Hypoactive deep tendon reflexes -
correct answer ✅1. Twitching
: A client with lactose intolerance is at risk for developing
hypocalcemia, because food products that contain calcium also
contain lactose. The normal serum calcium level is 9 to 10.5 mg/dL
(2.25 to 2.75 mmol/L). A serum calcium level lower than 9 mg/dL
(2.25 mmol/L) indicates hypocalcemia. Signs of hypocalcemia
include paresthesias followed by numbness, hyperactive deep
tendon reflexes, and a 267 positive Trousseau's or Chvostek's sign.
Additional signs of hypocalcemia include increased neuromuscular
excitability, muscle cramps, twitching, tetany, seizures, irritability,
and anxiety. Gastrointestinal symptoms include increased gastric
motility, hyperactive bowel sounds, abdominal cramping, and
diarrhea.
. The nurse is caring for a client with Crohn's disease who has a
calcium level of 8 mg/dL (2 mmol/L). Which patterns would the
nurse watch for on the electrocardiogram? Select all that apply.
1. U waves
2. Widened T wave
3. Prominent U wave

4. Prolonged QT interval
5. Prolonged ST segment -
correct answer ✅4. Prolonged QT interval
5. Prolonged ST segment
A client with Crohn's disease is at risk for hypocalcemia. The normal
serum calcium level is 9 to 10.5 mg/dL (2.25 to 2.75 mmol/L). A
serum calcium level lower than 9 mg/dL (2.25 mmol/L) indicates
hypocalcemia. Electrocardiographic changes that occur in a client
with hypocalcemia include a prolonged QT interval and prolonged
ST segment. A shortened ST segment and a widened T wave occur
with hypercalcemia. ST depression and prominent U waves occur
with hypokalemia.
The nurse reviews the electrolyte results of a client with chronic
kidney disease and notes that the potassium level is 5.7 mEq/L (5.7
mmol/L). Which patterns would the nurse watch for on the cardiac
monitor as a result of the laboratory value? Select all that apply.
1. ST depression
2. Prominent U wave
3. Tall peaked T waves
4. Prolonged ST segment
