CCRN Practice Exam 1
ST elevation in leads II, III, aVF is a?
Reciprocal changes will be seen in leads? - Answer-inferior wall MI
I, aVL
Initial priority of care for a pt experiencing sustained tonic clonic seizures? - Answer-Call for help and
safely guide pt to the floor
A pt presents with pneumonia and sepsis, received 4 days of abx and fluids, increasingly SOB, increase in
FiO2 requirements, CXR shows b/l infiltrates. ABG is 7.20/ 68/102/28. The pt is developing? - Answer-
ARDS = PaO2 </ 300
PaO2/FiO2 = 102/100%(1) = 102
What is a major complication of htn crisis? - Answer-Encephalopathy
What labs should closely be monitored if pt is given lisinopril? - Answer-Potassium
bc ACE inhibitor - blocks angiotensin II - decreases aldosterone
Pt with acute MI, in cardiogenic shock.
BP 86/42
HR 110
,Cardiac Index 1.7
SVR 1929
What med should be given? - Answer-Dobutamine
bc the goal here is to improve contractility and reduce afterload
What should you monitor closely post gastric bypass? - Answer-HR, RR, temp, WBC and MAP
Best intervention to promote safety of a pt recieving hemodialysis? - Answer-Direct visualization of the
connection be the machine and the access device
What mode of ventilation is this:
The ventilator is set to deliver 12 breaths/ min at a set volume. The volume of the remaining 8 breaths
varies. - Answer-SIMV - synchronized intermittent mandatory ventilation
What mode of ventilation is this:
Any additional breathes taken by the pt are assisted by the ventilator to achieve the prescribed volume -
Answer-CMV - controlled mandatory volume
A 45 yr old presents w sepsis. You administer 500 bolus of LR. What indicates that the intervention is
having its intended effect? - Answer-ScvO2 - 72%
A pt has been receiving VTE prophylaxis with SQ heprin since admission, 6 days ago. Today, plt count
decreased significantly to 43,000 and he was found to have a new DVT. What was the cause of this? -
Answer-HIT - Heprin induced thrombocytopenia
- drop in plt count
, - new DVT
Hemodynamics of R sided heart failure - Answer-Decreased CO/CI
Increased CVP
Decreased/Normal POAP
Increased SVR
Labs to expect w DI - Answer-Increased serum osmo
Decreased urine osmo
Increase serum NA
There is a lack of ADH
Hemodynamics of hypovolemic shock - Answer-Decreased CO
Decreased Preload
Increased Afterload
Increased SVR - to increase BP
Increase in HR- to compensate for
A pt w asthma exacerbation has an ABG of: 7.35/42/82/22
And a RR of 38 as he uses accessory muscles. What do you suspect? - Answer-Severe airflow obstruction
This ABG is not normal given their RR
Lab findings of a post-renal kidney injury d/t obstruction? - Answer-Decreased urine output
ST elevation in leads II, III, aVF is a?
Reciprocal changes will be seen in leads? - Answer-inferior wall MI
I, aVL
