Which client is at risk for the development of a potassium level of 5.5 mEq/L (5.5
mmol/L)?
1. The client with colitis
2. The client with Cushing's syndrome
3. The client who has been overusing laxatives
4. The client who has sustained a traumatic burn - ✔️✔️4. The client who has
sustained a traumatic burn
The normal potassium level is 3.5 to 5.0 mEq/L (3.5 to 5.0 mmol/L). A serum potassium
level higher than 5.0 mEq/L (5.0 mmol/L) indicates hyperkalemia. Clients who
experience cellular shifting of potassium in the early stages of massive cell destruction,
such as with trauma, burns, sepsis, or metabolic or respiratory acidosis, are at risk for
hyperkalemia. The client with Cushing's syndrome or colitis and the client who has been
overusing laxatives are at risk for hypokalemia.
. 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 - ✔️✔️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.
Hypokalemia appearance on EKG - ✔️✔️- 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. - ✔️✔️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
3. Negative Trousseau's sign
4. Hypoactive deep tendon reflexes - ✔️✔️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 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
