Clinical Flashcards

The PDCA cycle used for continuous quality improvement refers to __________.

Answer: plan-do-check-act

The PDCA cycle, or Plan-Do-Check-Act cycle, is a widely used iterative four-step management method for the control and continuous improvement of processes and products. It is a fundamental tool in quality assessment and performance improvement (QAPI) programs in healthcare, including dialysis centers. This systematic approach helps organizations identify problems, test solutions, evaluate results, and implement effective changes.

Which of the following hormones directs the bone marrow to produce more red blood cells?

Answer: Erythropoietin

Erythropoietin (EPO) is a hormone primarily produced by the kidneys that stimulates the bone marrow to produce red blood cells. In patients with kidney failure, the damaged kidneys cannot produce enough EPO, leading to anemia. This is why synthetic erythropoietin-stimulating agents are often prescribed as part of anemia management in dialysis patients.

Which of the following is a genetic (inherited) disease that can lead to kidney failure?

Answer: Polycystic kidney disease

Polycystic kidney disease (PKD) is a genetic disorder characterized by the growth of numerous fluid-filled cysts in the kidneys. These cysts gradually enlarge and impair kidney function, eventually leading to kidney failure in many individuals. It is one of the most common inherited causes of end-stage renal disease.

Normal saline has a sodium chloride concentration of ___________.

Answer: 0.90%

Normal saline, also known as 0.9% sodium chloride solution, is an isotonic solution commonly used in medical settings, including dialysis. Its concentration of 0.90% sodium chloride is approximately equivalent to the concentration of solutes in human blood plasma. This makes it suitable for intravenous administration without causing significant fluid shifts in cells.

As part of anemia management for patients receiving hemodialysis, the technician should ___________.

Answer: rinse back as much blood as possible

Anemia is a common and serious complication for hemodialysis patients due to various factors, including blood loss during treatment. By thoroughly rinsing back all blood from the dialyzer and blood lines at the end of a session, technicians minimize the amount of blood lost. This practice is crucial for conserving the patient's red blood cell count and supporting anemia management.

Patients receiving hemodialysis are at risk for amyloidosis. Which of the following symptoms may indicate amyloidosis?

Answer: Joint pain

Dialysis-related amyloidosis (DRA) is a condition where beta-2 microglobulin, a protein not adequately cleared by dialysis, accumulates in tissues. This accumulation often manifests as joint pain, particularly in the shoulders, wrists, and hands, and can also lead to carpal tunnel syndrome. Recognizing these musculoskeletal symptoms is important for identifying DRA in hemodialysis patients.

A patient who experiences numbness, tremors, muscle spasms, and muscle pain may have low levels of __________.

Answer: calcium

Low levels of calcium (hypocalcemia) can cause a range of neuromuscular symptoms, including numbness and tingling (paresthesias), muscle spasms (tetany), tremors, and muscle pain. Calcium plays a critical role in nerve and muscle function, and imbalances can significantly impact these systems. In dialysis patients, hypocalcemia can be a concern due to altered vitamin D metabolism and phosphate retention.

Which of the following laboratory tests is often done before and after hemodialysis to measure the effectiveness of dialysis in removing waste products from the body?

Answer: Blood urea nitrogen

Blood Urea Nitrogen (BUN) is a key waste product measured to assess kidney function and the effectiveness of dialysis. By comparing BUN levels before and after a dialysis treatment, healthcare providers can determine how much urea has been removed, which is a direct indicator of dialysis adequacy. This measurement helps ensure patients are receiving sufficient clearance of toxins.

A patient beginning hemodialysis usually has a hemoglobin test every _____________.

Answer: one to two weeks

Hemoglobin levels are crucial for monitoring anemia, a common complication in hemodialysis patients. For patients newly starting hemodialysis, or those with unstable hemoglobin levels, testing is typically done every one to two weeks. This frequent monitoring allows the healthcare team to promptly adjust anemia management strategies, such as erythropoietin-stimulating agents or iron supplements, to maintain target hemoglobin levels.

The most common treatment for patients with end-stage kidney disease in the United States is _____________.

Answer: daytime in-center hemodialysis

Despite the availability of various modalities, daytime in-center hemodialysis remains the most prevalent treatment option for patients with end-stage kidney disease in the United States. This is often due to factors like patient preference, medical suitability, social support, and insurance coverage. It provides structured care in a supervised clinical environment.

Which of the following is an indication that a patient may be losing fat and/or muscle mass even though he or she reaches the target dry weight after treatment?

Answer: Patient becomes short of breath if lying flat after treatment.

If a patient becomes short of breath when lying flat (orthopnea) even after reaching their target dry weight, it can indicate that their 'dry weight' is actually too low. This symptom suggests that the patient may be losing lean body mass (muscle and fat) instead of just excess fluid, leading to inadequate fluid volume in the vascular space and potential cardiac strain. It's a critical sign that the dry weight assessment needs re-evaluation.
