Saunders- NCLEX Flashcards
(45 cards)
Triage Levels
Emergent (red):
Immediate threat to life, requires immediate tx and continuous evaluation
ex) trauma, chest pain, severe respiratory distress or cardiac arrest, pt w/ limb amputation, pt w/ acute neurological deficits, chemical splashes to eyes
Urgent (yellow):
not life-threatening if treated w/in 1-2 hours, require continous evaluation every 30-60 min thereafter
ex) simple fracture, asthma w/o respiratory distress, fever, HTN, abdominal pain or renal stone
Nonurgent (green):
local injuries w/o complications and can wait several hours for medical tx, require evaluation every 1-2 hrs after.
ex) minor laceration, sprain, or cold symptoms
Dead or dying (black):
injuries to severe to benefit from care
Type of Leader
Autocratic:
- focused, maintains strong control, makes decisions, and addresses all problems.
- dominates the group and commands, rather than seeks suggestions or input
Situational:
- use a combo of styles based on needs of group and the tasks to be achieved
- work w/ the group to validate that the info gained is accurate and problem exists
- Take time to get to know the group
Democratic:
- participative, and would likely meet w/ each staff person individually to determine the staff member’s perception of the problem
- speak w/ staff about any issues and ask for input with developing a plan
Laissez-faire:
- passive and nondirective
- state what problem is and inform the staff that they needed to come up with a plan to “fix it”
Guidelines that the nurse should use when delegating and planning assignments
- ensure client safety
- be aware of individual variations in work abilities
- determine which tasks can be delegated and to whom
- match the task to the delegatee on teh basis of nurse practice act and appropriate position descriptions
- provide directions that are clear, concise, accurate, and complete
- validate the delegatee’s understanding of the directions
- communicate a feeling of confidence to the delegatee
- provide feedback promptly after the task is performed
- maintain continuity of care as much as possible when assigning pt care
Normal osmolality of plasma
270 - 300 mOsm/gk water
Osmolality refers to the number of osmotically active particles per kg of water; concentration of a solution
Hypotonic solution
when a solution contains a lower concentration of salt or solute than another, more concentrated solution
1/2 NS, 1/3 NS, 1/4 NS
- has less salt, and more water than isotonic sol’n
- lower osmolality than blody fluids
- WATER LEAVES SOL’N (vascular space) and ENTERS CELLS VIA OSMOSIS
Hypertonic solution
has higher concentration of solutes than another, less concentrated solution
3% NS, 5% NS, D10W, D5W with NS
- fluid pulled out of the cells
Electrolyte imbalance affect on ECG: wave changes
Hypocalcemia:
- prolonged ST segment
- prolonged QT interval
Hypercalcemia:
- shortened ST segment
- widened T wave
Hypokalemia:
- ST depression
- Shallow, flat, or inverted T wave
- Prominent U wave
Hyperkalemia:
- tall peaked T waves
- Flat P waves
- widened QRS complex
- prolonged PR interval
Hypomagnesemia:
- tall T waves
- depressed ST segment
Hypermagnesemia:
- prolonged PR interval
- widened QRS complexes
Absent P waves
atrial fibrillation
junctional rhythms
ventricular rhythms

PT and INR
for warfarin therapy
PT: 9.6 to 11.8 seconds (male adult); 9.5 to 11.3 seconds (female adult)
**PT should be 1.5 to 2x the labortory control value
INR: 2 to 3 for standard warfarin therapy
INR: 3 to 4.5 for high-dose warfarin therapy
BLEEDING PRECAUTIONS IF PT > 30 sec
aPTT
for heparin therapy
aPTT: 20 to 36 seconds, depending on the type of activator used
- **should be between 1.5 and 2.5 times normal when the client is receiving heparin therapy (so not less than 30 or greater than 90sec)*
- **BLEEDING PRECAUTIONS IF > 90sec*
serum GI lab studies
Albumin: 3.4 - 5
Ammonia: 10-80
ALT: 10-40
AST: 10-30
Amylase: 25-151 (chronic pancreatisis, level not to exceed 3x normal/ acute can be 5x normal)
Lipase: 10-140
Cholesterol: 140-199
LDLs: lower than 130
HDLs: 30-70
Triglycerides: lower than 200
Protein: 6-8
Total bilirubin: lower than 1.5 (pt with liver dz have prolonged clotting times and need prolonged pressure on punctures site)
Renal Function lab studies
serum Creat: 0.6-1.3 (increased levels indicate slowing glomerular filtration rate)
BUN: 8 -25 (increased level can indicate dehydration, below normal may be caused by FV overload)
WBC
WBC: 4500 - 11000
Differential: info on specific white blood cell types
“shift to the left” means that an increased number of immature neutrophils is present in the blood
