Normal Lab Values

Question 0

Creatinine- male

Answer 0

0.6-1.2 mg/dl

> 4mg/dl indicates serious impairment in renal function

Question 1

Creatinine-female

Answer 1

0.5-1.1 mg/dl

Question 2

BUN normal findings

Answer 2

Adult 10-20 mg/dl ( not specific to kidney)

GFR is best, then creatinine, then BUN

Question 3

Estimated GFR (creatinine clearance)????.?.

Answer 3

Male- 107-139 ml/ min

Female 87-107 ml/dl

Question 4

Magnesium normal

Answer 4

1.3-2.1 mEq/ L
Hypo- clinical manifestations- confusion, hyperactive deep tendon reflexes, tremors and seizures. Magnesium deficiency also predisposes to cardiac dysrhythmias. Resembles hypocalcemia, and may contribute to the development of hypocalcemia as a result of the decreased action of PTH.

Hyper-lethargy, drowsiness, nausea and vomiting., as increase- deep tendon reflexes are lost, followed by somnolence, and the resp and, ultimately cardiac arrest can occur.

Question 5

Magnesium

Answer 5

Hypo- produces neuromuscular and CNS hyper irritability.

Hyper-‘depresses neuromuscular and CNS functions.

Question 6

Phosphate imbalances

Answer 6

Hyper- neuromuscular irritability

Hypo- usually asymptomatic

Question 7

Sodium imbalances

Answer 7

Hyper- postural hypotension, weakness decreased skin turgor

Hypo- cellular swelling- first manifested in CNS

Question 8

Potassium

Answer 8

Hyper- leg cramping, weakness or paralysis of leg muscles. Should be monitored ECG for fatal dysrhythmias. Should receive IV calcium gluconate is they are having dysrhythmias.

Hypo- incidence of potential lethal dysrhythmias is increased. Skel muscle weakness and paralysis, including the resp muscles. Leading to shallow resp. And resp arrest.

Question 9

Calcium 9-10.5

Answer 9

Hyper- decreased memory, confusion, disorientation, fatigue, muscle weakness, constipation, cardia dysrhythmias, and renal calculi.

Hypo- muscle excitability resulting in tetany (muscular spasms)
