HCC II Exam 1 Questions With Complete Solutions
0.9 NaCl (normal saline) Correct Answer expands the ECF
volume, used in hypovolemic states, diabetic ketoacidosis,
metabolic alkalosis, hypercalcemia, hyponatremia, hemorrhage,
D/V, GI suction, fistulas, wounds, shock
3% NaCl (hypertonic saline) Correct Answer to increased ECF
volume, decrease cellular swelling, used to treat hyponatremia,
can cause intravascular volume overload, pulmonary edema,
assists in removing Intracellular fluid excess
5% NaCl Correct Answer treat symptomatic hyponatremia, can
cause intravascular volume overload and pulmonary edema
Anions Correct Answer Chloride, bicarb, phosphate, and
sulfate
CA++ 9.0-10.5 Correct Answer Evaluate endocrine function,
calcium metabolism, acid base balance, guide therapy in renal
failure, renal transplant, endocrine disorders, malignancies,
cardiac disease, skeletal disorders
Calcium Correct Answer 8.5-10.5 mg/dL
Calcium high Correct Answer Low phosphorus
Cations Correct Answer Na, k, hydrogen, Ma, Ca
CBC
,Hct Correct Answer measures % of packed RBCs in a whole
blood sample
CBC
HGB Correct Answer for maintaining shape of cell
CBC
Plt Correct Answer functionality of platelets, pts ability to clot
CBC
WBC Correct Answer Microliter of whole blood (can vary as
much as 2000 on a day of strenuous stress, exercise, or
digestion, also called a leukocyte count
Chronic Renal Failure Correct Answer kidney damage or a
decrease in the glomerular filtration rate (GFR) lasting for 3 or
more months
Chvostek's sign Correct Answer nerves in face are over
reactive to touch
Coagulation
International Normalized Ratio (INR): Correct Answer
Measures prothrombin time to monitor oral anticoagulant
therapy. Not used to screen for coagulopathies
Coagulation
Partial Thromboplastic Time (PTT) Correct Answer evaluate
all the clotting factors of the intrinsic pathway—except platelets.
Purpose is to screen for deficiencies of the clotting factors in the
, intrinsic pathways and to monitor the response to heparin
therapy
Coagulation
Prothrombin Time (PT) Correct Answer Measures the time
required for a fibrin clot to form. Purpose is to evaluate the
extrinsic coagulation system (factors V, VII, and X,
prothrombin, and fibrinogen) and to monitor response to oral
anticoagulant therapy
D5W Correct Answer sugar water free water, used for
hypernatremia, fluid loss and dehydration, contradicted for pts
needing resuscitation, early post op, increased ICP
Extracellular Fluid Correct Answer 20% of body weight
Fluid and Electrolyte Balance Correct Answer the process of
regulating the extracellular fluid volume, body fluid osmolality,
and plasma concentrations of electrolytes.
Hypercalcemia Correct Answer cancer, immobility; decreased
reflexes, fatigue, lethargy, cardiac dysrhythmias.
Hypercalcemia - >10.5 mg/dL
Causes Correct Answer Ca++ shift from bone to ECF
malignancy, hyperparathyroidism,
Excessive intake Ca/ Vit D,/ Vit A ; excessive C+ antacids
Lithium and Thiazide diuretic use
Hypercalcemia - >10.5 mg/dL
Signs Correct Answer GI: N/V, Constipation
