A nurse is assessing a client's comprehension of a pulmonary function test prior to the procedure. Which of the following client statements indicates to the nurse an understanding of the procedure?

Choice A Reason:
Reinforcing dietary teaching with a client who has heart disease is incorrect. Dietary teaching typically requires a higher level of assessment and critical thinking, often involving interpretation of lab values, medication interactions, and individualized dietary plans. This task is best suited for a Registered Nurse (RN).
Choice B Reason:
Providing postmortem care for a client who has just died is incorrect. Providing postmortem care involves emotional support, respect for the deceased, and proper handling of the body. This task is within the scope of practice for an RN and may also involve collaboration with other healthcare team members.
Choice C Reason:
Accompanying a client who just had a wound debridement to physical therapy is incorrect. Accompanying a client to physical therapy may involve monitoring the client's condition, providing assistance during the transfer, and communicating with the physical therapist about the client's status. This task typically requires an RN or may be appropriate for an assistive personnel under RN supervision.
Choice D Reason:
Obtaining a urine specimen from an older adult client is correct. Obtaining a urine specimen is a task that falls within the scope of practice for an LPN. It involves performing a routine procedure that requires technical skills but does not involve complex assessment or critical thinking beyond following established protocols.

Choice A Reason:
Herpes simplex virus (HSV) requires contact precautions when there are active lesions. Wearing a cover gown helps prevent the transmission of the virus through direct contact with the client or contaminated surfaces, indicating proper understanding of isolation guidelines.

Choice B Reason:
Protective isolation (also known as reverse isolation) is used for clients who are immunocompromised, and they require a positive airflow room, not a negative airflow room. Positive airflow rooms help keep contaminants out, while negative airflow rooms are used for clients with airborne infectious diseases to prevent the spread of pathogens to other areas.

Choice C Reason:
An N95 respirator mask is required for airborne precautions (e.g., for tuberculosis, measles, or varicella) rather than contact precautions. Contact precautions generally involve wearing gloves and a gown, but an N95 mask is not necessary.

Choice D Reason:
For clients with Clostridium difficile (C. difficile) infection, soap and water must be used for hand hygiene, not alcohol-based hand cleansers. Alcohol-based hand sanitizers are not effective against C. difficile spores, so proper handwashing with soap and water is essential to prevent the spread of this infection.
