A nurse is reviewing the laboratory values for a client who takes spironolactone and notes that the client's serum potassium level is 6.8 mEq/L. The nurse notifies the provider and anticipates that the provider will provide which of the following instructions?

Have the laboratory draw a blood sample for an erythrocyte sedimentation rate

Obtain a 12-lead ECG

Administer potassium gluconate 40 mEq orally

Restrict fluid intake

Answer and Explanation

The Correct Answer is B

Choice A reason : An erythrocyte sedimentation rate (ESR) test is not directly related to high serum potassium levels and would not be the immediate action in response to hyperkalemia.

Choice B reason : Obtaining a 12-lead ECG is a critical step when hyperkalemia is suspected because high potassium levels can cause life-threatening cardiac arrhythmias. An ECG can quickly reveal characteristic changes associated with hyperkalemia, allowing for prompt treatment.

Choice C reason : Administering potassium gluconate would be contraindicated in a patient with hyperkalemia, as it would further increase the serum potassium levels, potentially leading to severe complications.

Choice D reason : Restricting fluid intake is not a standard treatment for hyperkalemia. The management of hyperkalemia may include medications or procedures that promote the excretion of potassium or move potassium from the blood into the cells.

Correct Answer is D

Explanation

Choice A reason : The triglyceride level of 130 mg/dL is within the normal range, which is less than 150 mg/dL for adults. Therefore, this result does not place the client at risk for peripheral arterial disease.

Choice B reason : An HDL level of 84 mg/dL is considered good as it is higher than the minimum recommended level of 40 mg/dL for males and 50 mg/dL for females. Higher levels of HDL are protective against heart disease.

Choice C reason : A blood glucose level of 92 mg/dL is within the normal fasting range of 70 to 99 mg/dL. This indicates that the client does not have diabetes, which is a risk factor for peripheral arterial disease.

Choice D reason : An LDL level of 172 mg/dL is considered high since the optimal level for LDL is less than 100 mg/dL. High levels of LDL cholesterol can lead to atherosclerosis, increasing the risk for peripheral arterial disease.

Correct Answer is ["2"]

Explanation

Step 1 is to identify the prescribed dose of digoxin, which is 0.25 mg.

Step 2 is to identify the amount of digoxin available per tablet, which is 0.125 mg/tablet.

Step 3 is to calculate the number of tablets the nurse should administer per dose. This is done by dividing the prescribed dose by the amount available per tablet. So, 0.25 mg ÷ 0.125 mg/tablet = 2 tablets.

The nurse should administer 2 tablets per dose.
