Elecrtolyte and ABG's Flashcards
What is the normal magnesium range? (According to our current book!)
1.3-2.1 mEq/L
What is the normal serum sodium range?
135-145 mEq/L
What is the normal serum Potassium range?
3.5-5 mEq/L
Which electrolyte imbalance is considered life-threatening, even if only minor? Why?
Hypokalemia. Because potassium is within every cell. If serum levels drop, all tissues, especially muscle and nerve tissues, become less excitable/slow to respond.
When administering potassium, what warning would you give your patient?
Take during or after a meal. Potassium may cause nausea or vomiting if taken on an empty stomach.
What is a good way to remember how High or low potassium levels affect the body?
DO you remember “low and slow” from the first unit? It was in regards to dosing seniors, but it works for this also. If potassium is low you will be slow. If its high, your tissues will be overly excited.
What is the normal serum calcium range?
9-10.5 mg/dL
What is considered a normal serum phosphate level?
3-4.5 mg/dL
What important electrolyte imbalances are caused by alkalosis?
Hypocalcemia and hypokalemia.
What important electrolyte imbalances occur with acidosis?
Hyperkalemia.

7.35-7.45
What is the normal range for PaO2?
80-100
What is the normal range for HCO3?
22-26
What is the normal range for PaCO2?
35-45
What is the normal range for serum creatinine?
.5-1.4 mg/dL
