The healthcare provider prescribes the antibiotic tetracycline HCl for an adult client that arrived at an outpatient clinic. Which instruction should the nurse include in the teaching plan for this client?

Choice A reason: Telling the client to notify the nurse if the pain is not relieved is an important nursing action, but it is not the highest priority. The nurse should assess the client's pain level before and after administering the medication, and evaluate its effectiveness. If the pain is not relieved, the nurse should report it to the prescriber and consider other interventions.

Choice B reason: Advising the client that the medication should start to work in about 30 minutes is an informative nursing action, but it is not the highest priority. The nurse should educate the client about the expected onset, peak, and duration of action of the medication, and how to take it safely and effectively. However, this does not address any immediate risks or needs of the client.

Choice C reason: Administering a stool softener/laxative at the same time as the analgesic is a preventive nursing action, but it is not the highest priority. The nurse should anticipate and prevent potential side effects of the medication, such as constipation, which can be caused by codeine. However, this does not address any urgent or emergent issues of the client.

Choice D reason: Instructing the client to request assistance when ambulating to the bathroom is the highest priority nursing action, as it addresses a serious safety concern of the client. The nurse should protect the client from falls and injuries, which can be caused by codeine's sedative and drowsy effects. The nurse should also monitor the client's respiratory rate and level of consciousness, as codeine can cause respiratory depression and altered mental status.

Choice A reason: Monitoring for signs of sodium and fluid retention is not relevant to this situation, as broad spectrum antibiotics do not affect sodium or fluid balance. Sodium and fluid retention may be caused by other conditions such as heart failure, kidney disease, or liver disease.

Choice B reason: Obtaining wound and blood specimens for culture and sensitivity is most important before administering the first dose of a broad spectrum antibiotic, as this can help identify the specific type and strain of bacteria causing the infection and determine which antibiotic is most effective against it. Broad spectrum antibiotics are effective against a wide range of bacteria, but they may also kill beneficial bacteria and increase the risk of resistance or superinfection.

Choice C reason: Obtaining a complete blood count and serum electrolytes is not necessary before administering the first dose of a broad spectrum antibiotic, as these tests do not provide information about the type or severity of infection. A complete blood count may show an elevated white blood cell count or other changes in response to infection, but it does not identify the causative organism. Serum electrolytes may show abnormalities due to dehydration, vomiting, diarrhea, or other factors, but they do not indicate infection.

Choice D reason: Performing irrigation and topical antibiotic application to wound area is not sufficient before administering the first dose of a broad spectrum antibiotic, as this may not reach all sites of infection or eradicate all bacteria. Irrigation and topical antibiotic application may help clean and prevent further contamination of wound area, but they do not replace systemic antibiotic therapy.
