Prior to administering the evening dose of carbamazepine, the nurse noted that the client’s morning carbamazepine level was 8.4 mg/L. Which action should the nurse take?

Before administering the first dose of any antibiotic, it is essential to obtain a culture and sensitivity test to identify the causative organism and determine the most effective antibiotic to use. Administering a broad- spectrum antibiotic before obtaining a culture and sensitivity test may lead to the development of antibiotic-resistant strains of bacteria, making it more difficult to treat the infection in the future.

Options a, c, and d are not as important as obtaining a culture and sensitivity test. Monitoring for signs of sodium and fluid retention, irrigation and topical antibiotic application to the wound area, and completing blood count and serum electrolytes are important, but obtaining a culture and sensitivity test is the priority.

The correct answer is C. Instruct the client to request assistance when ambulating to the bathroom.

Choice A reason:

Advise the client that the medication should start to work in about 30 minutes.

While it is important to inform the client about the onset of action of the medication, this is not the highest priority. Codeine, an opioid, can cause dizziness and sedation, which increases the risk of falls. Therefore, safety measures take precedence over informing the client about the medication’s onset time.

Choice B reason:

Administer a stool softener/laxative at the same time as the analgesic.

Opioids like codeine can cause constipation, so administering a stool softener or laxative is a good practice. However, this action is not the highest priority when considering the immediate safety of the client. Ensuring the client’s safety from potential falls due to dizziness or sedation is more urgent.

Choice C reason:

Instruct the client to request assistance when ambulating to the bathroom.

This is the correct answer because codeine can cause dizziness, sedation, and orthostatic hypotension, increasing the risk of falls. Ensuring the client requests assistance when moving can prevent potential injuries, making it the highest priority nursing action.

Choice D reason:

Tell the client to notify the nurse if the pain is not relieved.

While it is important for the client to communicate about the effectiveness of pain relief, this is not the highest priority. The immediate concern is the client’s safety due to the sedative effects of codeine. Therefore, preventing falls and injuries takes precedence.
