A nurse is caring for a client who has a prescription for a potassium supplement. The client tells the nurse that the pill is too large to swallow and refuses to take it. The nurse offers to break the pill into two smaller pieces. The nurse is demonstrating which of the following ethical principles?

A. A urine specific gravity of 1.015 is within the normal range (1.005–1.030). While fluid volume excess may lead to a lower specific gravity due to urine dilution, this value does not indicate fluid overload and is considered normal.
B. A hematocrit level of 42% is within the normal range for adults (men: 38–50%, women: 35–45%). Hematocrit levels tend to decrease in fluid volume excess due to hemodilution, but this value does not suggest fluid overload.
C. A urine pH of 6.5 is within the normal range (4.5–8.0). Urine pH reflects the acid-base balance rather than fluid status and is not a reliable indicator of fluid volume excess.
D. A BUN level of 5 mg/dL is below the normal range (10–20 mg/dL). In fluid volume excess, the dilution of blood plasma can lead to decreased BUN levels. This low BUN value, in conjunction with clinical symptoms, supports the diagnosis of fluid volume excess.

A. Restrict the client's visitors to the immediate family: While tuberculosis is a communicable disease, restricting visitors to the immediate family is not a standard precautionary measure. Visitors should be educated about infection control measures and individuals with active tuberculosis
may need to wear masks in certain situations.
B. Assign the client to a negative pressure airflow room: Correct. Clients with active tuberculosis should be placed in a negative pressure airflow room to prevent the spread of infectious airborne particles to other areas of the facility. Negative pressure ensures that air from the room does not flow to other parts of the facility.
C. Discard personal protective equipment outside the client's room: Personal protective equipment (PPE) should be removed and discarded according to facility policy, which often includes removing PPE inside the client's room and properly disposing of it afterward. The nurse should follow standard precautions for infection control.
D. Have the client wear a HEPA mask during transportation throughout the facility: While wearing a HEPA mask may be necessary for clients with tuberculosis, it is not related to the initial admission process. Clients with active tuberculosis may be asked to wear a HEPA mask during transportation when they need to leave their negative pressure room.
