A nurse is caring for a client whose serum potassium level is 5.3 mEq/L. Which of the following scheduled medications should the nurse plan to administer?
Digoxin
Lisinopril
Potassium iodide
Furosemide
The Correct Answer is D
A. Digoxin: Digoxin requires caution with elevated potassium levels, as hyperkalemia can increase the risk of digoxin toxicity. A potassium level of 5.3 mEq/L is borderline high, so it should be used cautiously.
B. Lisinopril: Lisinopril, an ACE inhibitor, can also increase potassium levels. It may not be the best choice for this client due to the elevated potassium.
C. Potassium iodide: Potassium iodide would further increase the client's potassium level and is contraindicated.
D. Furosemide: Furosemide is a loop diuretic that can help to lower serum potassium levels by promoting potassium excretion. Therefore, it is appropriate for this client with an elevated potassium level.

Correct Answer is ["A","C","D"]
Explanation
A. Perform passive range of motion exercises. Passive range of motion exercises help maintain circulation and reduce venous stasis, which is crucial for preventing pulmonary embolism in clients who are immobile.
B. Place pillows under the client's knees when in bed. Placing pillows under the knees can actually promote venous stasis and increase the risk of a pulmonary embolism. It is better to keep the legs flat to encourage circulation.
C. Assess legs for redness. Regular assessment of the legs for redness, swelling, or warmth helps in the early detection of deep vein thrombosis (DVT), which can lead to pulmonary embolism if not addressed.
D. Apply elastic compression stockings. Elastic compression stockings promote venous return from the legs to the heart and help prevent DVT, thereby reducing the risk of pulmonary embolism.
E. Massage the calves every shift. Massaging the calves can dislodge a thrombus and potentially lead to a pulmonary embolism. Instead, interventions should focus on preventing thrombus formation.
Correct Answer is A
Explanation
A. BUN 45 mg/dL and creatinine 8 mg/dL: These levels indicate significant kidney impairment; elevated BUN and creatinine levels are typical in chronic kidney disease.
B. BUN 8 mg/dL and creatinine 0.7 mg/dL: These values are within normal limits and suggest good kidney function, not indicative of chronic kidney disease.
C. BUN 10 mg/dL and creatinine 0.3 mg/dL: These values are much lower than expected in chronic kidney disease, indicating normal renal function.
D. BUN 23 mg/dL and creatinine 1.0 mg/dL: While these levels show mild elevation, they do not reflect the more severe impairment typically seen in chronic kidney disease.
