A nurse is caring for a client experiencing kidney failure. The nurse recognizes that kidney failure causes the loss of which of the following processes integral to maintaining homeostasis?
Distribution of protein
Filtration of the blood
Metabolism of medications
Ability to hold urine
The Correct Answer is B
A. Distribution of protein: While protein distribution may be affected in kidney disease, it is not a primary function of the kidneys.
B. Filtration of the blood: The kidneys are responsible for filtering waste products and excess substances from the blood. In kidney failure, this filtration process is impaired, leading to the accumulation of toxins in the body.
C. Metabolism of medications: Although the kidneys do play a role in drug excretion, drug metabolism primarily occurs in the liver. Kidney failure may affect the excretion phase.
D. Ability to hold urine: While kidney failure can affect urinary function, the ability to hold urine is primarily a bladder function, not directly a function of the kidneys.

Correct Answer is B
Explanation
A. “If my breathing begins to feel tight, I will use the fluticasone immediately." Fluticasone is a corticosteroid, and it is not a rescue medication. It is used for long-term control and does not provide immediate relief for acute symptoms.
B. "I will be sure to use the albuterol nebulizer before the fluticasone." Albuterol is a bronchodilator and should be used first to open the airways, allowing better absorption of fluticasone when used afterward.
C. "I do not need to rinse my mouth after completing the albuterol and fluticasone." Rinsing the mouth after using fluticasone (a corticosteroid) is important to prevent oral thrush. Albuterol alone does not require rinsing, but fluticasone does.
D. "I will use both medications immediately after exercising." Albuterol is often used as a pre-exercise medication for asthma, but fluticasone should be used as directed for maintenance, not as an immediate post-exercise medication.
Correct Answer is B
Explanation
A. The patient is hypertensive. Hypertension is not a prerequisite for starting BPH medication; in fact, some BPH medications can lower blood pressure.
B. The patient has had a prostate examination, including measurement of the PSA level. A prostate examination and PSA measurement are important for diagnosing BPH and ruling out prostate cancer before starting treatment.
C. The patient is still sexually active. Sexual activity status is not a determining factor for administering BPH medication.
D. The patient has not had a vasectomy. Vasectomy status does not influence the treatment of BPH.
