A patient is experiencing nausea and decreased appetite during drug therapy with a tetracycline antibiotic.
What is the nurse’s best advice to the patient?

Choice A rationale:

Administering the medications using a 3-mL medication syringe is not the best practice. While it is possible to use a 3-mL syringe for medication administration, it is not the most efficient or safest method. A larger syringe allows for easier administration and reduces the risk of creating too much pressure which could potentially damage the PEG tube.

Choice B rationale:

Applying firm pressure on the syringe’s piston to infuse the medication is not recommended. This can create too much pressure in the PEG tube and could potentially cause damage. It is generally advised to allow the medication to flow into the tube via gravity. Choice C rationale:

Flushing the tubing with 30 mL of saline after the medication has been given is the correct technique. This helps to ensure that all of the medication has been administered and also helps to keep the tube clear of any potential blockages.

Choice D rationale:

Using the barrel of the syringe, allowing the medication to flow via gravity into the tube is a common practice. However, it is not the only step in the process. It is also important to flush the tube before and after medication administration to ensure all medication is delivered and to maintain the patency of the tube.

Choice A rationale:

Administering the antibiotic dose before obtaining the cultures could potentially affect the results of the cultures. Antibiotics are designed to kill or inhibit the growth of bacteria, so administering them before obtaining the cultures could lead to false negatives. This could lead to incorrect or delayed diagnosis and treatment.

Choice B rationale:

While obtaining the urine culture before administering the antibiotic dose is a good step, it should not be done before obtaining the blood culture. Blood cultures are usually obtained before urine cultures because they can help identify bacteria or fungi in the blood. This can be crucial in diagnosing conditions like sepsis. Furthermore, administering the antibiotic dose before obtaining the blood culture could affect the results of the culture.

Choice C rationale:

Obtaining the blood culture before administering the antibiotic dose is a good step, but the urine culture should also be obtained before the antibiotic dose is administered. Administering the antibiotic dose before obtaining all necessary cultures could affect the results of the cultures and lead to incorrect or delayed diagnosis and treatment.

Choice D rationale:

This is the correct sequence of actions. The nurse should first obtain both blood and urine cultures before administering the antibiotic dose. This is because the antibiotic could potentially kill or inhibit the growth of bacteria, which could affect the results of the cultures. By obtaining the cultures first, the healthcare team can ensure they are getting accurate results that have not been influenced by the antibiotics. This can lead to a more accurate diagnosis and more effective treatment plan.
