A client has just experienced a 90-second tonic-clonic seizure and has the following arterial blood gas results: pH 7.12, HCO3 22 mEq/L, PaCO2 55 mmHg, PaO2 60 mmHg. Which intervention is the most appropriate?

Apply a paper bag over the clients nose and mouth.

Administer 50 mL of 20% glucose and 20 units of regular insulin.

Administer 50 mL of sodium bicarbonate intravenously.

Apply oxygen by mask or nasal cannula.

Answer and Explanation

The Correct Answer is D

A. Appling a paper bag over the client's nose and mouth is used for hyperventilation or respiratory alkalosis, not for respiratory acidosis. In this case, it would worsen the client’s condition by increasing CO2 retention.

B. Administering 50 mL of 20% glucose and 20 units of regular insulin is appropriate for hyperkalemia or diabetic ketoacidosis, not respiratory acidosis following a seizure.

C. Administering 50 mL of sodium bicarbonate intravenously is used for severe metabolic acidosis. This client’s acidosis is primarily respiratory in origin, making this choice inappropriate.

D. Applying oxygen by mask or nasal cannula helps correct the low oxygen levels and supports respiration post-seizure.

Correct Answer is B

Explanation

A. Digoxin is used to control the heart rate in atrial fibrillation but does not directly prevent the common complication of thromboembolism.

B. Warfarin is an anticoagulant used to prevent thromboembolic complications, such as stroke, which are common in atrial fibrillation due to the formation of clots in the atria.

C. Furosemide is a diuretic used to manage fluid retention, often in heart failure, but it does not prevent thromboembolism.

D. Lisinopril is an ACE inhibitor used to manage hypertension and heart failure, but it does not prevent thromboembolic complications.

B. Total cholesterol of 280 mg/dL is above the recommended level, increasing the risk of atherosclerosis.

C. Serum albumin is within the normal range and does not indicate atherosclerosis risk.

D. HDL cholesterol at 50 mg/dL is considered within a normal protective range and is not indicative of atherosclerosis risk.

E. Triglycerides of 200 mg/dL are also elevated, contributing to the risk for atherosclerosis.
