Hypokalemia appearance on EKG - correct answer - U waves
- inverted T waves
- depressed ST segment
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. - correct answer 1. Obtain an intravenous (IV)
infusion pump.
2. Monitor urine output during 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
, BSN 246
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
