Q

PREPARING FOR THE DIAGNOSTIC TESTING Assessment

A
  1. Verify patient identification.
  2. Check medical history (current medications, herbal supplements, allergies
    and hypersensitivities, recorded findings of previous diagnostic tests relative
    to the procedure.
  3. Assess for presence, location, and characteristics of physical and
    communicative limitations or preexisting conditions.
  4. Monitor the client’s knowledge of why the test is being performed.
  5. Obtain vital to establish baseline data.
  6. Monitor level of hydration and weakness for clients who are NPO
    (nothing by mouth), especially geriatric and pediatric populations.
  7. Check general patient condition, preparedness for the test, anxiety level.

PREPARING FOR THE DIAGNOSTIC TESTING
Client Teaching : (IMPORTANT- INFORMED CONSENT)

A
  1. Explain reason for test and what to expect, how long it will take.
  2. RESTRICTIONS (activities, food, etc.)
  3. What is the specimen to be collected? Give proper instruction on collection.
    a. Sputum: cough deeply, do not clear throat.
    b. Urine: voided, clean-catch specimen, time to collect.
    c. Blood: What food were taken, fasting?
  4. No objects (jewelry or hair clips) to obscure x-ray film.
  5. If dyes are to be ingested or injected, explain.
    E.g. Barium: taste, consistency, aftereffects (stools lightly colored for 24–
    72 hours, can cause obstruction or impaction).
    Glucose drink for PPBS
  6. Post test instructions.

Q

BLOOD CHEMISTRY

A

COMMON GUIDELINES:
BLOOD CHEMISTRY
1. Perform tests in the morning preferably between 7:00 and 10:00.
2. Perform tests on an empty stomach (fasting means the state after about 12 hours not
eating meals and fluids12-hr)
FASTING required for: CHOLESTEROL, LIPID profile, GLUCOSE, GLUCOSE TOLERANCE
TEST, CORTISOL, FOLIC ACID, FERRITIN, IRON, PHOSPHORUS.
3. OVER FASTING: body starts to use its own protein, especially with a small supply of fat.
(glucose levels too low, increased ketone compounds, reduction in iron and hemoglobin
levels.)
4. Some medicines should be discontinued.
5. Avoid any intense physical exercise or sexual activity the day before a test.
6. Alcohol and cigarettes at least a day before, and smoking for about an hour before the
test.
7. Relax and avoid stress. Sit. Prolonged standing causes fluids to move from the inside of
the vessels to the intra-tract space and blood thickens.
8. Take hormones on the right days of the cycle.
9. Do not OVER EAT before a test.
10. For some blood tests, you may be asked to drink extra water to help keep more fluid in
your veins or to drink water 15 to 20 minutes before certain urine tests.

75
Q

BLOOD

Main extracellular ion.
Monitor the effectiveness of diuretics.

Nurse’s Role
Don’t draw blood from an arm with an IV drip.

A

SODIUM {Na}

76
Q

BLOOD

Major intracellular cation that regulate
acid-base equilibrium, control cellular
water balance, and transmit electrical
impulses in skeletal and cardiac muscles.

Nurse’s Role
Patients with elevated WBC counts and platelet counts may have falsely elevated potassium levels.

A

Potassium K

77
Q

BLOOD

most abundant extracellular body anion that
counterbalances cations Na and acts as buffer
during oxygen and carbon dioxide exchange in
red blood cells (RBCs). Aids in digestion and
maintaining osmotic pressure and water balance.

Nurse’s Role
Any condition accompanied by
prolonged vomiting, diarrhea, or both will alter chloride levels

A

CHLORIDE (Cl)

78
Q

BLOOD

needed in the blood-clotting mechanisms,
regulates neuromuscular activity, acts as a
cofactor that modifies the activity of many
enzymes, and has an effect on the metabolism of
calcium

Nurse’s Role
Prolonged use of magnesium products
causes increased serum levels.
Long-term parenteral nutrition therapy
or excessive loss of body fluids may
decrease serum levels

A

MAGNESIUM (Mg)

79
Q

BLOOD

Important in bone formation, energy storage and
release, urinary acid-base buffering, and
carbohydrate metabolism. It is absorbed from
food and is excreted by the kidneys. High
concentrations of phosphorus are stored in bone
and skeletal muscle.

Nurse’s Role
Instruct the client to fast before the test

A

PHOSPHORUS (P)

80
Q

cation absorbed into the bloodstream from
dietary sources and functions in bone
formation, nerve impulse transmission, and
contraction of myocardial and skeletal muscles.
Calcium aids in blood clotting by converting
prothrombin to thrombin.

A

TOTAL CALCIUM
(Ca), IONIZED

81
Q

Calcium affected by:

A

*Decreased protein levels
*Use of anticonvulsant medications.

82
Q

-measure of solute concentration of blood. (sodium ions, glucose, urea);
usually estimated by doubling the serum sodium because sodium is a
major determinant of serum osmolality.

A

Serum Osmolality

83
Q

Part of the bicarbonate-carbonic acid buffering system and mainly
responsible for regulating the pH of body fluids.
Ingestion of acidic or alkaline solutions may affect results.

A

SERUM BICARBONATE (HCO3-)

84
Q

GLUCOSE STUDIES include the ff. tests:

A
  1. HbA1c (glycosylated hemoglobin),
  2. Fasting blood sugar, RBS
  3. Glucose tolerance test
  4. Diabetes mellitus antibody panel
85
Q

-help diagnose diabetes mellitus and hypoglycemia.

A

FASTING BLOOD SUGAR (FBS)

86
Q

glucose level is taken 2 hours after eating.
Nursing Consideration
-Instruct the client to fast for 8 to 12 hours before the test.
-Instruct a client with diabetes mellitus to withhold morning insulin or oral hypoglycemic until after the blood is drawn.

A

PPBS (POST PRANDIAL
BLOOD SUGAR)

87
Q

Aids in the diagnosis of DM. If the glucose
levels peak at higher than normal at 1 and 2 hours after
injection or ingestion of glucose and are slower than normal to
return to fasting levels, then diabetes mellitus is confirmed.

Nursing Considerations
1. Instruct the client to eat a high-carbohydrate (200 to
300 g) diet for 3 days before the test; avoid alcohol, coffee,
and smoking for 36 hours before the test; avoid strenuous
exercise for 8 hours before and after the test; fast for 10 to
16 hours before the test.
2. Instruct the client with diabetes mellitus to withhold
morning insulin or oral hypoglycemic medication.
3.Test may take 3 to 5 hours, requires IV or oral
administration of glucose, and the taking of multiple blood
samples.
4. INFORM PATIENT TO STRICTLY FOLLOW
INSTRUCTIONS.

A

GLUCOSE TOLERANCE TEST
(GTT)

88
Q
  • blood glucose bound to hemoglobin and a reflection of
    how well blood glucose levels have been controlled for
    the past 3 to 4 months. Hyperglycemia in clients with
    diabetes is usually a cause of an increase in the HbA1c.

Nursing Consideration:
Fasting is not required before
the test.

A

(HbA1c) GLYCOSYLATED
HEMOGLOBIN

89
Q

Used to evaluate insulin resistance
and to identify type 1 diabetes and
clients with a suspected allergy to
insulin.

A

DIABETES MELLITUS
AUTOANTIBODY PANEL)

90
Q

determines the kidney function of an individual

A

RENAL FUNCTION TESTS

91
Q

-measures the amount of creatinine in the blood.
Increased in kidney disease. Usually a creatinine level more than 1.2 for women
and more than 1.4 for men may be a sign that the kidneys are not working like
they should.

A

SERUM CREATININE

92
Q

measure of excretory function of
kidneys.
a. GFR of 60 or more together with a normal urine albumin test is normal.
b. GFR less than 60, indicates kidney disease.

aids in the digestion of complex carbohydrates;
excreted by kidneys. In ACUTE PANCREATITISamylase level may exceed five times the normal
value; the level starts rising 6 hours after the onset
of pain, peaks at about 24 hours, and returns to
normal in 2 to 3 days after the onset of pain.
In CHRONIC PANCREATITIS, the rise in serum
amylase usually does not normally exceed three
times the normal value.

CARDIAC MARKERS &
SERUM ENZYMES

108
Q

-enzyme found in muscle and brain tissue that
reflects tissue catabolism resulting from cell
trauma.

A

CREATINE KINASE (CK)

109
Q

, an oxygen-binding protein that is found in
striated (cardiac and skeletal) muscle, releases oxygen at
very low tensions. Any injury to skeletal muscle will cause a
release of myoglobin into the blood. Myoglobin rise in 2-4
hours after an MI making it an early marker for determining
cardiac damage

113
Q
  1. ELISA - A single reactive ELISA test by itself is not
    conclusive; should be repeated in duplicate with the same
    blood sample; if the result is repeatedly reactive, follow-up
    tests using Western blot or IFA.
  2. WESTERN BLOT- A positive Western blot or IFA results is
    considered confirmatory for HIV.
  3. IMMUNOFLUORESCENCE ASSAY (IFA).
    Note: A positive ELISA but not confirmed by Western blot or
    IFA should be repeated after 3 to 6 months.
