A nurse is caring for a client who has schizophrenia and is taking an antipsychotic medication. Which of the following screening tools should the nurse use to identify tardive dyskinesia?

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.

The correct answer is B. Notify the charge nurse about the situation. Informed consent is when a healthcare provider explains a medical treatment to a patient before the patient agrees to it. The patient has the right to know their state of health, the diagnosis, and the treatments available, and to choose any alternative. The nurse is responsible for obtaining consent when initiating care, and reviewing consent before providing the care ordered by another health care professional. If the patient does not understand why the procedure is necessary, the nurse should notify the charge nurse or the physician who ordered the procedure, so that they can provide more information and answer any questions.

The nurse should not ask the client to sign the consent form anyway (A), as this would violate the patient's right to autonomy and self-determination.

The nurse should not remind the client about the specifics of the procedure (C) or explain to the client that the procedure will help treat his diagnosis (D), as these are not within the nurse's scope of practice and may be considered as giving medical advice.
