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
,5. Widened QRS complexes - 🧠 ANSWER ✔✔Answer: 3. Tall peaked T
waves
5. Widened QRS complexes
Rationale: The client with chronic kidney disease is at risk for
hyperkalemia. The normal potassium level is 3.5 to 5.0 mEq/L (3.5 to 5.0
mmol/L). A serum potassium level greater than 5.0 mEq/L (5.0 mmol/L)
indicates hyperkalemia. Electrocardiographic changes associated with
hyperkalemia include flat P waves, prolonged PR intervals, widened QRS
complexes, and tall peaked T waves. ST depression and a prominent U
wave occurs in hypokalemia. A prolonged ST segment occurs in
hypocalcemia.
Test-Taking Strategy(ies): Focus on the subject, a client with chronic
kidney disease and the electrocardiographic changes that occur in a
potassium imbalance. From the data in the question you need to determine
that this condition is a hyperkalemic one. From this point, you must know
the electrocardiographic changes that are expected when hyperkalemia
exists. Remember that tall peaked T waves, flat P waves, widened QRS
complexes, and prolonged PR interval are associated with hyperkalemia.
,The nurse instructs a client with chronic kidney disease who is receiving
hemodialysis about dietary modifications. The nurse determines that the
client understands these dietary modifications if the client selects which
items from the dietary menu?
1. Cream of wheat, blueberries, coffee
2. Sausage and eggs, banana, orange juice
3. Bacon, cantaloupe melon, tomato juice
4. Cured pork, grits, strawberries, orange juice - 🧠 ANSWER ✔✔Answer: 1.
Cream of wheat, blueberries, coffee
Rationale: The diet for a client with chronic kidney disease who is receiving
hemodialysis should include controlled amounts of sodium, phosphorus,
calcium, potassium, and fluids, which is indicated in the correct option. The
food items in the remaining options are high in sodium, phosphorus, or
potassium.
Test-Taking Strategy(ies): Focus on the subject, dietary modification for a
client with chronic kidney disease. Think about the pathophysiology of this
disorder to recall that sodium needs to be limited. Noting the items
sausage, bacon, and cured pork will assist in eliminating these options.

apply.
1. Place the client on a cardiac monitor.
2. Notify the primary health care provider (PHCP).
3. Put the client on NPO (nothing by mouth) status except for ice chips.
4. Review the client's medications to determine whether any contain or
retain potassium.
5. Allow an extra 500 mL of intravenous fluid intake to dilute the electrolyte
concentration. - 🧠 ANSWER ✔✔Answer: 1. Place the client on a cardiac

Rationale: The normal potassium level is 3.5 to 5.0 mEq/L (3.5 to 5.0
mmol/L). A potassium level of 7.0 is elevated. The client with hyperkalemia
is at risk of developing cardiac dysrhythmias and cardiac arrest. Because of
