A nurse is observing an assistive personnel (AP) take a client's tympanic temperature. Which of the following actions should the nurse identify as an indication that the AP understands how to perform the procedure?
The AP inserts the probe with a straightforward motion.
The AP positions the client facing her.
The AP pulls the pinna up and back
The AP points the probe posteriorly.
The Correct Answer is C
The correct answer is choice C. The AP pulls the pinna up and back.
Choice A rationale:
Inserting the probe with a straightforward motion is not sufficient to ensure an accurate reading. Proper positioning of the ear canal is necessary to get an accurate tympanic temperature.
Choice B rationale:
Positioning the client facing the AP is not relevant to the accuracy of the tympanic temperature measurement. The focus should be on the correct technique for inserting the probe.
Choice C rationale:
Pulling the pinna up and back is the correct technique for adults and children over 3 years old. This action straightens the ear canal, allowing for an accurate temperature reading.
Choice D rationale:
Pointing the probe posteriorly is not a standard guideline for taking a tympanic temperature. The probe should be aimed towards the eardrum for an accurate measurement.

Correct Answer is A
Explanation
The correct answer is A. Clean the wound from the center to the outer edges.
Rationale: The nurse should clean the wound from the center to the outer edges to prevent contamination of the wound bed by bacteria or debris from the surrounding skin. The nurse should wear clean gloves, not sterile gloves, to remove the dressing, as wet-to-dry dressings are not sterile and do not require a sterile technique.
The nurse should remove the tape by pulling parallel to and away from the skin, not from the center of the dressing, to minimize skin damage and pain. The nurse should not moisten the dressing before removal, as this would defeat the purpose of wet-to-dry dressings, which are intended to debride necrotic tissue by adhering to it and pulling it off when dry.
Correct Answer is B
Explanation
The correct answer is B. Productive cough with thick mucus. Pertussis, also known as whooping cough, is a highly contagious respiratory infection caused by Bordetella pertussis bacteria. It causes severe coughing spells that can interfere with breathing and produce a characteristic whooping sound when inhaling. The cough may also be accompanied by thick mucus that can be difficult to clear. Therefore, a nurse should expect to see a productive cough with thick mucus as a manifestation of pertussis in a child. The other options are not typical manifestations of pertussis, but rather of other conditions. A beefy, red tongue may indicate vitamin B12 deficiency or pernicious anemia. Facial erythema may indicate fever, allergy, or inflammation. Peeling of the hands and feet may indicate Kawasaki disease, a rare inflammatory disorder that affects the blood vessels.
