Why would a client benefit from a thiazide diuretic over a loop diuretic?

1. They can be taken on an as-needed basis.
2. They do not cause electrolyte imbalance.
3. Possible dehydration is not a factor.
4. The frequency of adverse effects is much lower.

Question 2

A client has been diagnosed with hyperkalemia. Which medication would the nurse expect to give?

1. Potassium chloride
2. Furosemide (Lasix)
3. Calcium carbonate (TUMS)
4. Sodium polystyrene sulfate (Kayexalate)

Answer to Question 1

4

Rationale 1:They can be taken on an as-needed basis is incorrect because all diuretics can cause dehydration and electrolyte imbalance, and should be taken on a regular schedule to monitor effectiveness.
Rationale 2:They do not cause electrolyte imbalance is incorrect because all diuretics can cause dehydration and electrolyte imbalance, and should be taken on a regular schedule to monitor effectiveness.
Rationale 3:Possible dehydration is not a factor is incorrect because all diuretics can cause dehydration and electrolyte imbalance, and should be taken on a regular schedule to monitor effectiveness.
Rationale 4: Side effects from thiazides are generally minor, and rarely cause discontinuation of therapy.

Global Rationale: Side effects from thiazides are generally minor, and rarely cause discontinuation of therapy.

Answer to Question 2

4

Rationale 1: Potassium chloride would raise potassium levels more.
Rationale 2: Furosemide (Lasix) is not given to treat hyperkalemia.
Rationale 3: Calcium carbonate (TUMS) is not given to treat hyperkalemia.
Rationale 4: In severe cases, serum potassium levels may be lowered by administering sodium polystyrene sulfate (Kayexalate), a resin that removes potassium ions by exchanging them for sodium ions in the large intestine. This agent is given concurrently with a laxative to promote rapid evacuation of the potassium. Sodium polystyrene sulfate is available in oral and enema formulations.
