What are the normal ranges for RBC?
What can increase levels
What happens to levels during pregnancy?
Males: 4.7-6.1 million
Female: 4.2-5.4 million
What are the normal ranges for H&H? What are the nursing implications
Hemoglobin - Male 14-18 Female 12-16 Newborn 14-24
High altitude living increases value, slight decrease during pregnancy. Drug
therapy can alter values.
Hematocrit - Male 42-52 Female 37-47 Newborn 44-64
Prolonged stasis from vasoconstriction secondary to the tourniquet can alter
values. Abnormalities in RBC size may alter Hct values
What are the normal ranges for WBC?
What can increase values?
What can decrease values?
How long does the postpartum period of pregnancy affect normal ranges? What
range is normal during the postpartum period?
Both genders 5000-10000 Newborn 9000-30000
Anesthetics, stress, exercise, and convulsions can increased values.
, 2
Drug therapy can decrease values.
24-28 hr postpartum: a count as high as 25000 is normal
Exercise and high altitudes can cause an increase levels
pregnancy usually lower values
drug therapy can alter values
Never draw a specimen from an arm with an infusing IV.
What are the normal ranges for PLATELETS?
What may increase values?
What may decrease values?
What drugs decrease values?
Both Genders: 150000-400000
Living at high altitudes, exercising strenuously or taking oral contraceptives may
increase values
decreased values may be caused by hemorrhage, DIC, reduced production of
platelets, infections, use of prosthetic heart valves, and drugs.
Drugs that decrease platelets: acetaminophen, aspirin, chemotherapy, H2
blockers, INH, Levaquin, streptomycin, sulfonamides, thiazide diuretics.
What are the normal ranges for K+? What should you keep in mind when getting a
specimen?
3.5-5 is normal range for potassium
Exercise of the forearm with tourniquet in place may cause an increased level.
Hemolysis of specimen can result in a falsely elevated value
, 3
What are the normal ranges for Na+? What should you consider when collecting a
specimen?
136-145 is a normal sodium range
Do Not collect from an arm with an infusing IV solution
What are the normal ranges for Ca+?
What type of drug can increase calcium levels?
What are two tests with positive results that are associated with hypocalcemia?
How do you preform the two tests?
9-10.5 for adults. slightly lower in the elder
Use of thiazide diuretics can cause increased levels of calcium
Positive Chvostek and Trousseau tests are associated with hypocalcemia.
• Chvostek sign: contraction of ipsilateral facial muscles when the facial nerve is
tapped just in front of the ear.
• Trousseau sign: carpopedal spasm elicited by inflating a sphygmomanometer
above systolic BP for 3 minutes.
What are the normal ranges for Mg+?
What may high magnesium levels indicate?
What may low magnesium levels indicate?
1.7-2.2
A high magnesium level may indicate: Addison disease
Chronic renal failure, Dehydration, Diabetic acidosis
Oliguria
