A client with chronic kidney disease (CKD) is receiving calcium acetate 667 mg PO. A decrease in which blood value indicates to the nurse that the medication is having the desired effect?
Potassium.
Calcium.
Phosphate.
pH.
The Correct Answer is C
Choice A reason:
Calcium acetate is not used to lower potassium levels. Potassium levels in the blood are typically managed through dietary restrictions, medications like potassium binders, and dialysis in patients with CKD. The normal range for blood potassium levels is 3.5 to 5.2 mEq/L for adults.
Choice B reason:
Calcium acetate can increase calcium levels in the blood, not decrease them. It is important to monitor calcium levels to avoid hypercalcemia, which can lead to complications such as vascular calcification and cardiac issues. The normal range for blood calcium levels is 8.6 to 10.2 mg/dL.
Choice C reason:
Calcium acetate is used to lower phosphate levels in patients with CKD. It works by binding to dietary phosphate in the intestines, forming insoluble calcium phosphate that is excreted in the stool. This helps prevent hyperphosphatemia, a common issue in CKD patients. The normal range for blood phosphate levels is 2.5 to 4.5 mg/dL.
Choice D reason:
Calcium acetate does not directly affect blood pH levels. Blood pH is regulated by the kidneys and lungs, and the normal range is 7.35 to 7.45. While CKD can affect acid-base balance, calcium acetate’s primary role is to manage phosphate levels.

Correct Answer is D
Explanation
Choice A reason:
Resuming a diet that consists of milk, cream, and bland foods is not the most critical instruction for a client taking esomeprazole. While bland foods can help reduce gastric irritation, they do not address the primary concern of monitoring for serious side effects. Esomeprazole is a proton pump inhibitor (PPI) that reduces stomach acid, and dietary changes alone are not sufficient to manage potential complications.
Choice B reason:
Calling the clinic if diarrhea or headache occurs when taking esomeprazole is important, but it is not the most critical instruction. Diarrhea and headache are common side effects of esomeprazole, but they are usually not severe. The client should be aware of these potential side effects, but the primary concern is monitoring for signs of gastrointestinal bleeding.
Choice C reason:
Once pain subsides, NSAID therapy should not be resumed without consulting the healthcare provider. NSAIDs can cause significant gastrointestinal issues, including ulcers and bleeding. The client should be advised to avoid NSAIDs unless specifically directed by their healthcare provider.
Choice D reason:
Notifying the healthcare provider of the passage of black stools is the most critical instruction. Black stools can indicate gastrointestinal bleeding, which is a serious side effect of both NSAIDs and esomeprazole. Immediate medical attention is necessary if this occurs to prevent further complications.
Correct Answer is A
Explanation
Choice A Reason:
Use a straw to ingest: Ferrous sulfate elixir can cause staining of the teeth. Using a straw helps to minimize contact with the teeth, thereby reducing the risk of staining. This method ensures that the medication is ingested directly into the throat, bypassing the teeth.
Choice B Reason:
Swallow undiluted: Swallowing ferrous sulfate elixir undiluted is not recommended because it can cause gastrointestinal irritation. Diluting the elixir in water or juice can help to minimize this irritation and improve absorption.
Choice C Reason:
Mix with an antacid: Mixing ferrous sulfate with an antacid is not advisable because antacids can interfere with the absorption of iron. Iron is best absorbed in an acidic environment, and antacids neutralize stomach acid, thereby reducing iron absorption.
Choice D Reason:
Take with a glass of milk: Taking ferrous sulfate with milk is not recommended because calcium in milk can inhibit the absorption of iron. It is best to take iron supplements on an empty stomach or with a source of vitamin C, such as orange juice, to enhance absorption
