Nursing interventions such as taking daily weights, I&O, and monitoring specific gravity relate to which kidney function?

Regulation of water balance

Regulation of acid-base balance

Regulation of blood pressure

Regulation of metabolic wastes

Answer and Explanation

The Correct Answer is A

Choice A reason: The regulation of water balance by the kidneys involves maintaining the appropriate volume and concentration of body fluids. By taking daily weights, nurses can assess fluid retention or loss, while monitoring intake and output (I&O) helps track fluid balance. Specific gravity measures the concentration of urine, which provides information about the kidneys' ability to concentrate or dilute urine. These interventions directly relate to the kidneys' role in regulating water balance.

Choice B reason: Regulation of acid-base balance by the kidneys involves maintaining the proper pH levels in the blood through excretion or retention of hydrogen ions and bicarbonate. While important, this function is not the primary focus of interventions like daily weights, I&O, and specific gravity monitoring, which are more related to water balance.

Choice C reason: The regulation of blood pressure by the kidneys is achieved through the renin-angiotensin-aldosterone system, which controls blood volume and systemic vascular resistance. Although fluid balance can indirectly affect blood pressure, the specific interventions mentioned are more directly related to water balance than blood pressure regulation.

Choice D reason: Regulation of metabolic wastes involves the kidneys filtering and excreting waste products from the blood. This function is vital for overall health, but interventions like daily weights, I&O, and specific gravity monitoring are more focused on assessing fluid balance rather than directly measuring waste elimination.

Correct Answer is ["A","C","E","F","G"]

Explanation

Choice A reason: Decreased calcium is expected in end-stage chronic kidney disease (CKD) due to impaired kidney function. The kidneys are responsible for converting vitamin D into its active form, which helps in calcium absorption. Reduced kidney function leads to decreased active vitamin D, resulting in lower calcium levels.

Choice B reason: Decreased blood urea nitrogen (BUN) is not typical in CKD. Instead, BUN levels usually increase because the kidneys are less able to remove urea from the blood. Urea is a waste product of protein metabolism, and elevated BUN is indicative of impaired kidney function.

Choice C reason: Decreased hemoglobin is expected in CKD due to reduced production of erythropoietin by the kidneys. Erythropoietin stimulates the production of red blood cells, and a lack of it leads to anemia, reflected by lower hemoglobin levels.

Choice D reason: Decreased potassium is not typically seen in CKD. In fact, potassium levels often increase because the kidneys are less able to excrete it. Hyperkalemia (high potassium) is a common complication in CKD and requires careful monitoring.

Choice E reason: Elevated creatinine is expected in CKD. Creatinine is a waste product of muscle metabolism, and elevated levels indicate impaired kidney function as the kidneys are less able to clear it from the blood.

Choice F reason: Increased phosphorus is a common finding in CKD due to the kidneys' reduced ability to excrete phosphorus. This can lead to hyperphosphatemia, which can cause secondary hyperparathyroidism and further complications.

Choice G reason: Decreased glomerular filtration rate (GFR) is a hallmark of CKD. GFR measures how well the kidneys are filtering blood, and a lower GFR indicates reduced kidney function. It is used to stage the severity of CKD.

A. Age B. Hypertension C. Obesity D. Smoking E. Stress

Correct Answer is ["B","C","D","E"]

Explanation

Choice A reason: Age is a non-modifiable risk factor for coronary artery disease. While it is a significant risk factor, individuals cannot change their age. Modifiable risk factors are those that individuals can alter through lifestyle changes or medical interventions to reduce their risk of developing coronary artery disease.

Choice B reason: Hypertension, or high blood pressure, is a modifiable risk factor for coronary artery disease. By managing blood pressure through lifestyle changes, medications, and regular monitoring, individuals can reduce their risk of developing coronary artery disease. Effective management of hypertension includes reducing sodium intake, maintaining a healthy weight, exercising regularly, and taking prescribed medications.

Choice C reason: Obesity is a modifiable risk factor for coronary artery disease. Individuals can work towards achieving and maintaining a healthy weight through dietary changes, increased physical activity, and behavioral modifications. Losing weight can significantly lower the risk of coronary artery disease by improving blood pressure, cholesterol levels, and overall cardiovascular health.

Choice D reason: Smoking is a major modifiable risk factor for coronary artery disease. Quitting smoking can dramatically reduce the risk of developing coronary artery disease and other cardiovascular conditions. Smoking cessation programs, medications, and support groups can help individuals successfully quit smoking and improve their cardiovascular health.

Choice E reason: Stress is a modifiable risk factor for coronary artery disease. Chronic stress can contribute to the development of coronary artery disease by affecting blood pressure, cholesterol levels, and overall heart health. Managing stress through relaxation techniques, exercise, counseling, and mindfulness practices can help reduce the risk of coronary artery disease.
