Q

Why hypocalcemic when in end stage renal failure?

A
  • Kidneys manufacture Vit D, low Vit D levels lead to hypocalcemia
  • Phosphorus and Ca work together in the presence of Vit D. No Vit D: the Ca goes down and the Phos goes up

Q

Polyphagia

A
  • aka hyperphagia
  • Excessive or extreme hunger
  • Diabetic polyphagia: In uncontrolled diabetes where blood glucose levels remain abnormally high (hyperglycemia), glucose from the blood cannot enter the cells - due to either a lack of insulin or insulin resistance - so the body can’t convert the food you eat into energy. This lack of energy causes an increase in hunger.

39

What is a glomerulus?

A

A tiny ball-shaped structure composed of capillary blood vessels actively involved in the filtration of the blood to form urine. The glomerulus is one of the key structures that make up the nephron, the functional unit of the kidney.

Why weigh someone in end-stage renal failure?

A

Kidneys do not filter so no urine production = no output

A

condition that happens before the kidney (ie. shock, infection) no blood going to the kidneys

51
Q

Intra renal failure

A

Problem at the level of the Kidney (ie stones, cysts, infection of kidney)

52
Q

Post renal failure

A

Problem post kidney effecting the kidney. (ie Bladder isn’t putting out and you have a clogged up catheter forcing fluid back into the kidneys. Prostate problems in guys force the urine back up into the kidneys. Kidney stone in the ureter. )

53
Q

End stage renal failure:

A
  • the kidneys can’t function

- transplant or dialysis needed

54
Q

How does urine move down the ureters?

-Nursing interventions
:Filter urine for passed stones
:Encourage fluids
:Monitor output
:Pain meds

61
Q

Glomerular filtration rate (GFR)

A

Test used to check how well the kidneys are working. Specifically, it estimates how much blood passes through the glomeruli each minute. Glomeruli are the tiny filters in the kidneys that filter waste from the blood

62
Q

Cause of glomerular nephritis

A

Strep

Insulin produced by the body

65
Q

Glycogenolysis

A

Breakdown of liver glycogen

66
Q

Ketoacidosis

A

An insulin deficit that causes fat stores of the body to break down, resulting in continued hyperglycemia and mobilization of fatty acids

67
Q

Neuropathy

A

Neurological damage resulting in an alteration or loss in sensation

68
Q

Ketosis

A

An accumulation of ketone bodies produced during oxidation of fatty acids

A

Formation of glucose from fats and proteins

A

A metabolic hormone that aids the cells in taking in glucose from the blood

71
Q

Hyperglycemia

A

An elevated blood glucose level

72
Q

Exogenous Insulin

A

Insulin produced outside the body

73
Q

Diabetes Mellitus

A

A metabolic condition in which the body had inadequate insulin to utilize blood glucose levels

74
Q

Hyperosmolar Hyperglycemic Status (HHS)

A

A metabolic disorder characterized by plasma osmolarity of 340 mOsm/L or greater (normal range is 280-300 mOsm/L), greatly elevated blood glucose levels (over 600 mg/dL), and altered levels of consciousness

79
Q

Pyuria

A

Pus in the urine

80
Q

Oliguria

A

Urine output of less than 400 mL/day. This will result in renal failure if it isn’t reversed

Q

Cytoscopy

A
  • lighted scope inserted into the bladder
  • Typically done under anesthesia
  • You could expect to see some bleeding after this has been done
82
Q

Hydronephrosis

A

The swelling of a kidney due to a build-up of urine. It happens when urine cannot drain out from the kidney to the bladder from a blockage or obstruction. Hydronephrosis can occur in one or both kidneys.

83
Q

Polycystic Kidney Disease (PKD)

A

An inherited disorder in which clusters of cysts develop primarily within your kidneys, causing your kidneys to enlarge and lose function over time. Cysts are noncancerous round sacs containing fluid. The cysts vary in size, and they can grow very large

84
Q

A

Medical condition characterized by abnormally high levels of nitrogen-containing compounds (such as urea, creatinine, various body waste compounds, and other nitrogen-rich compounds) in the blood.

85
Q

Stress Incontinence

A

Occurs when physical movement or activity — such as coughing, sneezing, running or heavy lifting — puts pressure (stress) on your bladder. Stress incontinence is not related to psychological stress.

86
Q

Urge Incontinence

A

Occurs when you have a sudden urge to urinate. In urge incontinence, the bladder contracts when it shouldn’t, causing some urine to leak through the sphincter muscles holding the bladder closed. Other names for this condition are: overactive bladder. bladder spasms.

87
Q

Functional Incontinence

A

Form of urinary incontinence in which a person is usually aware of the need to urinate, but for one or more physical or mental reasons they are unable to get to a bathroom. The loss of urine can vary, from small leakages to full emptying of the bladder.

88
Q

Overflow Incontinence

A

The involuntary release of urine—due to a weak bladder muscle or to blockage—when the bladder becomes overly full, even though the person feels no urge to urinate.
