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?

A.

Digoxin

B.

Lisinopril

C.

Potassium iodide

D.

Furosemide

Answer and Explanation

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 C

Explanation

A. "Use the peak expiratory flow meter once per week." The peak expiratory flow meter is usually recommended for daily use in asthma management to monitor lung function and detect any changes early.

B. "Take cromolyn sodium at the first sign of breathing difficulty." Cromolyn sodium is a mast cell stabilizer and is used as a preventative medication rather than for quick relief of symptoms, so it should be taken regularly as prescribed, not only when symptoms arise.

C. "Avoid triggers that cause an attack." Avoiding known asthma triggers is an important part of asthma management to prevent attacks and exacerbations.

D. "You should stop playing basketball, but you can swim instead." Exercise should not necessarily be avoided; instead, it should be managed appropriately with pre-treatment if needed. Avoiding all sports activities is not generally recommended.

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.
