NUR 211 EXAM 1 WITH 100%
CORRECT ANSWERS 2025
What ECG changes might you see in a patient with hypokalemia?
correct answers >> - Inverted T wave
- ST depression
- Prominent U wave
What part of the ECG represents early ventricular repolarization?
correct answers >> ST segment
What does the P-wave represent? correct answers >> atrial
depolarization/ contraction in response to the SA node
What ECG changes would you expect to see in a patient with
hyperkalemia? correct answers >> peaked T-waves
What is the treatment for a patient with PEA? correct answers
>> CPR, defib, epi
What are the indications for inserting a central venous access
device? correct answers >> long term IV therapy:
- fluids
- chemo
- nutrition
- blood products
- vesicants (meds with pH <5 or >9, osmo >600)
,How is CVAD placement verified? correct answers >> X-ray --
they are radiopaque
What are the 4 types of CVADs? correct answers >> 1.
peripherally inserted central catheter (PICC)
2. nontunneled central line
3. tunneled central line
4. implanted ports
How long can a PICC line be used? correct answers >> 7 days
to several months
Where is a PICC line inserted? correct answers >>
peripherally (basilic or cephalic vein at AC)
How are incompatible drugs given to a patient with a PICC line?
correct answers >> in separate ports
What are the nursing responsibilities when caring for a patient
with a PICC line? correct answers >> - keep dressing secured
and sterile
- keep line patent by flushing at intervals as ordered and assess
patency Q shift
When teaching a patient with HF about s/sx that indicate a need
to contact the primary health care provider, which clinical
manifestations would the nurse include? correct answers >>
- extreme/ unusual fatigue
, - coughing at night
- difficulty breathing
Which compensatory changes occur in the C/V system during
pregnancy? correct answers >> - Increased blood volume
- Increased cardiac output
- enlargement of the heart
Which adverse hemodynamic effects typically occur when a client
develops tachycardia? correct answers >> - decreased
ventricular filling time
- lower cardiac output
- weaker pulse quality
what is the expected therapeutic effect of digoxin? correct
answers >> - increased contractile force of the myocardium
- slows the HR
- increases CO
- increase the stroke volume of the heart
- decreases the refractory period of the AV node and decreases
conduction through the SA and AV nodes
What clinical manifestations are expected of a patient with
chronic PAD? correct answers >> intermittent claudication
( pain when exercising) and thickened toenails
