A nurse is preparing to administer ceftriaxone using the z-track technique to a client who has gonorrhea. After the nurse performs hand hygiene and reconstitutes the medication, identify the sequence the nurse should use to administer the medication. (Move the steps, placing them in the order of performance. Use all the steps.)

Elevate the head of the client's bed for 1 hr after the feeding. This is because elevating the head of the client's bed to at least 30 degrees can help prevent aspiration and gastric reflux.

Choice B is incorrect because administering the feeding solution at a cold temperature can cause discomfort and diarrhea.

Choice C is incorrect because rotating the jejunostomy tube once per day can cause irritation and trauma to the stoma site.

Choice D is incorrect because flushing the tube with 90 mL of sterile water before and after the feeding is not necessary as long as the tube is adequately flushed before and after each feeding.

The explanation for why the other choices are not answered: B – Administering the feeding solution at a cold temperature can cause discomfort and diarrhea, so it should not be done. C – Rotating the jejunostomy tube once per day can cause irritation and trauma to the stoma site, so this is not the correct action. D – Flushing the tube with 90 mL of sterile water before and after the feeding is unnecessary to do as long as the tube is adequately flushed before and after each feeding. Thus, this is not the correct answer.

Palpable area of induration, greater than 10 mm (0.4 in) in diameter. This indicates a positive tuberculin skin test (TST) reaction for a person with no known risk factors for TB infection. A positive TST reaction means that the person has been infected with Mycobacterium tuberculosis, the bacterium that causes TB disease, and needs further testing to confirm the diagnosis and rule out active TB disease.

The other choices are not correct because:

- Choice A. Nonpalpable area of redness, less than 5 mm (0.2 in) in diameter. This indicates a negative TST reaction for any person, regardless of their risk factors for TB infection. A negative TST reaction means that the person has not been infected with Mycobacterium tuberculosis or has a very low level of immune response to the bacterium.

- Choice B. Area of ecchymosis, greater than 12 mm (0.5 in) in diameter. This indicates a bruise or bleeding under the skin, not a TST reaction. Ecchymosis is not caused by the injection of tuberculin purified protein derivative (PPD) into the skin, but by trauma or injury to the blood vessels.

- Choice C. Tenderness at the injection site. This indicates a mild local reaction to the injection of tuberculin PPD into the skin, not a TST reaction. Tenderness is not measured in millimeters of induration (firm swelling), which is the standard way of reading TST results.
