A nurse is caring for a client with CKD stage 4. The nurse notes that the ordered medications include potassium chloride elixir 40 mEq by mouth 2 times a day. Prior to administering the medication, the nurse monitors the client's serum potassium level, which is 5.1 mEq/L (5.1 mmol/L). Which intervention is most important for the nurse to implement? 

A. Ask the pharmacist to supply a tablet rather than an elixir since the client is on fluid restriction. 

B. Hold the dose of potassium chloride and contact the HCP to report the serum potassium level. 

C. Administer the dose of potassium chloride and document the serum potassium level in the medical record. 

D. Calculate the milliliters of medication needed and record the amount on the fluid intake record. 

Hold the dose of potassium chloride and contact the HCP to report the serum potassium level.

The serum potassium level is elevated, and administering additional potassium in any form is potentially dangerous to the client.

Ask the pharmacist to supply a tablet rather than an elixir since the client is on fluid restriction.

The healthcare provider (HCP) must be contacted regarding this change. Since the administration of this prescription would be unsafe for the client in any form, there is another intervention that should be implemented.

Administer the dose of potassium chloride and document the serum potassium level in the medical record.

This is not an appropriate intervention considering the client's elevated serum potassium level.

Skidmore-Roth, L. (2021). Mosby’s 2021 Nursing Drug Reference. (34thedition). St. Louis, Missouri. Elsevier. Pg. 1021, 1023.


Calculate the milliliters of medication needed and record the amount on the fluid intake record.

If the potassium level was within normal limits and the medication was to be given, this would be an appropriate intervention. However, since the potassium level is high, this is not the correct intervention.

A patient with CKD stage 4 has a hemoglobin level of 7.8 g/dL (78 g/L). What action should the nurse take? 

A. Obtain a urine specimen to assess for hematuria.

B. Obtain an order to start an erythropoietin stimulating agent (ESA).

C. Continue to observe the client. 

D. Send the client to the hospital for a blood transfusion.  


Hemoglobin is decreased as the kidneys become less able to produce erythropoietin necessary for the formation of red blood cells. ESA's will replace the erythropoietin levels.

Linton, A., Matteson, M. (2020). Medical-Surgical Nursing. (7th edition). St. Louis, Missouri. Elsevier. Pg. 540, 832.


Obtain a urine specimen to assess for hematuria.

CKD does not result in hematuria. Clients with CKD will have proteinuria.

Obtain an order to start an erythropoietin stimulating agent (ESA).

Hemoglobin is decreased as the kidneys become less able to produce erythropoietin necessary for the formation of red blood cells. ESA's will replace the erythropoietin levels.

Linton, A., Matteson, M. (2020). Medical-Surgical Nursing. (7th edition). St. Louis, Missouri. Elsevier. Pg. 540, 832.


Continue to observe the client.

A hemoglobin level less than 8 g/dL (80 g/L) should be considered critical and should be addressed by the healthcare provider (HCP).


Send the client to the hospital for a blood transfusion.

In kidney clients who may be eligible for transplant, a blood transfusion should be avoided if possible.

Which assessment finding indicates to the nurse that the desired outcome of the calcium acetate has been achieved in the client with CKD?

A. Serum glucose of 90 mg/dL (5.0 mmol/L). 

B. Serum phosphorous of 4.0 mg/dL (1.29 mmol/L). 

C. Serum calcium level of 10.2 mg/dL (2.55 mmol/L).  

D. Serum hemoglobin of 12 g/dL (120 g/L). 

Serum phosphorous of 4.0 mg/dL (1.29 mmol/L).

Calcium acetate acts as a phosphate binder, reducing the high serum phosphorous levels commonly found in the client with CKD.



Serum glucose of 90 mg/dL (5.0 mmol/L).

This normal glucose level is managed with the client's glipizide.

Skidmore-Roth, L. (2021). Mosby's 2021 Nursing Drug Reference. (34thedition). St. Louis, Missouri. Elsevier. Pg. 613.


Serum phosphorous of 4.0 mg/dL (1.29 mmol/L).

Calcium acetate acts as a phosphate binder, reducing the high serum phosphorous levels commonly found in the client with CKD.

Skidmore-Roth, L. (2021). Mosby's 2021 Nursing Drug Reference. (34thedition). St. Louis, Missouri. Elsevier. Pg. 215.


Serum calcium level of 10.2 mg/dL (2.55 mmol/L).

Calcium acetate is a calcium supplement used to lower phosphorus levels. A side effect of this medication is that it can elevate serum calcium levels.

Skidmore-Roth, L. (2021). Mosby's 2021 Nursing Drug Reference. (34thedition). St. Louis, Missouri. Elsevier. Pg. 215.


Serum hemoglobin of 12 g/dL (120 g/L).

Hemoglobin is not affected by the use of calcium acetate.

The nurses is caring for a patient with CKD stage. Which expected outcome should be included in the nurse's teaching plan? 

A. Client will adhere to a low-protein diet. 

B. Client will avoid canned and processed foods. 

C. Client will identify the need to avoid fresh fruits and vegetables. 

D. Client will identify the need to increase their fluid intake. 

Clients on ESRD should restrict sodium to 2-4 grams per day. Canned and processed foods are high in sodium.

Which expected outcome should be included in the nurse's teaching plan?


Client will adhere to a low-protein diet.

Generally, clients on dialysis should not restrict protein in their diets. They should consume as much high biological quality value (HQV) protein such as dairy, eggs, meat, and fish as they can manage.

Client will identify the need to avoid fresh fruits and vegetables.

Because fresh fruits and vegetables provide much needed vitamins, they do not need to be avoided. However, those fruits that are high in potassium should not be eaten in excessive amounts.

Client will identify the need to increase their fluid intake.

The client receiving hemodialysis will more typically need to restrict sodium and fluid intake, rather than increase the amounts consumed.
