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?

pH.

Calcium.

Potassium.

Phosphate.

Answer and Explanation

The Correct Answer is D

pH: Calcium acetate is not directly related to changes in blood pH. Therefore, monitoring pH levels would not indicate the effectiveness of the medication for CKD.

B) Calcium: Calcium levels may be affected by calcium acetate, but the primary goal of using calcium acetate in CKD is to reduce phosphate levels, not calcium levels. Therefore, monitoring calcium levels would not directly indicate the effectiveness of the medication.

C) Potassium: Calcium acetate is not typically used to affect potassium levels. Monitoring potassium levels would not indicate the effectiveness of calcium acetate for CKD.

D) Phosphate: This is the correct answer. Calcium acetate is a phosphate binder commonly used in CKD to help lower elevated phosphate levels. A decrease in phosphate levels in the blood would indicate that the medication is having the desired effect in controlling phosphate levels, which is important in managing CKD and preventing complications associated with hyperphosphatemia. Therefore, monitoring phosphate levels is essential to assess the effectiveness of calcium acetate therapy in CKD.

Correct Answer is D

Explanation

Begin cardioversion to stabilize heart rhythm: Cardioversion is not the appropriate intervention for digoxin toxicity. Digoxin toxicity can cause arrhythmias, but the initial action should be to assess and manage the underlying cause, rather than immediately proceeding to cardioversion.

B) Give digoxin by another route to slow absorption: Slowing the absorption of digoxin is not the appropriate action for treating digoxin toxicity. Instead, the focus should be on managing the existing toxicity and preventing further absorption by withholding additional doses.

C) Administer potassium to stabilize the heart rate: While potassium may be indicated as part of the treatment for digoxin toxicity, particularly if hypokalemia is contributing to the toxicity, it is not the initial action. The priority is to assess the client’s acid-base and electrolyte values to identify any abnormalities contributing to the toxicity.

D) Check acid-base and electrolyte values: This is the correct action. Digoxin toxicity can be exacerbated by electrolyte imbalances, particularly hypokalemia, hypercalcemia, and hypomagnesemia. Therefore, assessing the client’s acid-base and electrolyte values is essential to identify and correct any abnormalities contributing to the toxicity. Once identified, appropriate interventions can be implemented to manage the toxicity and stabilize the client’s condition.

A. Intolerance to cold. B. Constipation. C. Restlessness. D. Decreased appetite.

Correct Answer is C

Explanation

A) Intolerance to cold: Intolerance to cold is a common symptom of hypothyroidism, not a sign of taking too much levothyroxine sodium. Therefore, this symptom would not indicate an overdose of the medication.

B) Constipation: Constipation can be a symptom of hypothyroidism, and it may improve with appropriate thyroid hormone replacement therapy. It is not typically associated with taking too much levothyroxine sodium.

C) Restlessness: This is the correct answer. Restlessness, anxiety, nervousness, or feeling jittery are symptoms of hyperthyroidism, which can occur if the client is taking too much levothyroxine sodium. If the dose of levothyroxine is too high, it can lead to hyperthyroid symptoms, even though the medication is intended to treat hypothyroidism.

D) Decreased appetite: Decreased appetite is not a typical symptom of taking too much levothyroxine sodium. In fact, weight loss is more commonly associated with hyperthyroidism, which can occur if the dose of levothyroxine is too high. However, decreased appetite alone may not specifically indicate an overdose of levothyroxine.
