- Front
- Back
wide complex non-perfusing tachycardia |
V tach |
|
Narrow QRS Tachy |
SVT |
|
No p-waves, fibrillatory f-waves, variable R-R intervals |
A fib |
|
Wide QRS typically less than 40bpm |
Idioventricular rate |
|
L vent HF produces what s/s |
Pulm. edema. Blood in L vent has difficulty with forward flow-- engorges L Atria and engorged pulmonary return causing the pulm edema |
|
Administer to pt's with R Ventricular MI (RVMI) to maintain CO |
IV crystalloids. W/ RVMI the R vent pump function is damaged and blood doesn't pump efficiently leading to decreased L vent filling and decreased CO. Increasing prefload (volume of blood entering R vent will result in increased blood volume ejected, leading to incresed SV and CO.) If still hypotensive p 2L, consider inotrope swuch ad dobutamine. Nitro/MS contraindicated decreases CO and causes hypotension. IV colloids ok w/ low H&H |
|
MI pt >85 yo most common abnormal presentation |
SOB. |
|
QRS represents what mechanical event |
Vent. contraction |
|
P wave mechanical event |
atrial contraction |
|
T wave mechanical event |
Vent. relaxation |
|
Atrial relaxation |
not displayed on ECG as a specific waveform because it cooccurs with vent. depolarization and is electrically insignificant |
|
Successfully defib pt. HR regular, rate 86, no pulses palpable |
PEA-- electrical disturbance in the electrical/mechanical activity of heart |
|
Cardiac tamponade |
Occurs w/ rapid accumulation of blood in pericardial sac-- decreased ventricular filling.
hypotension, muffled heart tones, distended neck veins |
|
What indicates fibrinolytic therapy has been effective Txment of a STEMI? |
Typically a relief from pain, resoluation of the ST-segments, and reperfusion dysrhthymias such as accelerated idioventricular rhythms. Fibrinolytic therapy isn't coronary-specific... so you can expect bleeding to occur at the puncture and ejection sites. |
|
Can't get peripheral access ... cardiac arrest, what next? |
IO intraosseous provides access to non-collapsible marrow venous plexus. Rapid, reliable & safe for crystalloids/colloids, blood, meds |
|
What is the rationale for heprin or LMWH for a pt with ACS? |
It inhibits further thrombin (clot) time. Heparin/LMWH does NOT lyse current present clots.
Heparin/LMWH can cause thrombocytopenia or fewer platelets therefore a lower PLT count. |
|
New onset A fib w/ RVR in asthmatic patient.. Pt A&O, bp 119/62, HR 158, RR 22. First line med? |
diltiazem (Cardizem) |
|
Pt with implated cardioverter/debrillator (ICD) report syncope. Monitor shows NSR suddently yells that the device went off & shocked him. What is next? |
Place a magnet on the device to temporarilty deactivate it and prevent inappropriate firing of the defib. until the device can be interrogated and corrected as necessary
The device should fire when the pt has a shockable rhythym --not NSR. If combined with pacemaker, it may also perform demand-pacing functions. |
|
Pt dx w/ IWMI (inferior wall MI) What is the most common dysrhtymmia to occur? |
bradycardias are often seen in the presence of IWMIs due to ischemia to the R coronary artery. |
|
What is angina? |
Ischemic CP occurring when myocardial O2 demand exceeds O2 supply. |
|
Elderly pt w 2-hr Hx of dizziness/fatigue. ECG is irreg, no p-waves. Suspects the pt's s/s are due to? |
A fib w/ RVR. |
|
Most common dysrhythmmia in older adults? What occurs pysiologically? Why can't older adults tolerate it? |
A fib Loss of atrial kick or coordinated filling/pumping of blood into the vents which typically makes up 30% of CO. When the vent rate increaswes, they don't fill completely which decreases CO even more. Older adults have a decreased ability to compensate (and don't tolerate) the drop in CO as well as young pt's. More likely to report fatigue, weakness, dizziness |
|
ST elevation in V4, V5, and Leads I and AVL |
lateral wall MI |
|
ST changes leads II, III, and AVF |
Inferior wall MI |
|
ST Elevation in leads V1-V4 |
anterior septal MI |
|
Cardioversion synchs w/ |
ventricular depolarization (QRS complex) |
|
Purpose of B-blockers with STEMI |
AHA reccomends within 24h... it reduces morbidity and mortality w/ no contraindications. |
|
adenosine (Adenocard) What happens? |
interrupts conduction at the AV node causing apparent aystole that can last 10secs... allows the SA node to take over and regular impulses to conduct.
Complex gets more narrow and rate decreases. Narrows the QRS complex. |
|
Assessing a pt in high speed, head on MVC... bp 100/50 HR 110, RR 22, LUQ abraisons. Focused organ assessment? |
Pancreas is in the LUQ behind the stomach in the retroperitoneal area. Direct blunt force to the epigastric area may result in pancreatic injury with a mortality rate as high as 50%. Also, the spleen, duodenum, jejunum, ileum, transverse/descending colons, and stomach. |
|
Newly Dx pt with liver failure... s/s: cognitive changes, irratibility, some muscle rigidity and hyperreflexia, what is another expected sx? |
Asterixis-- a flapping tremor usually of the hand... an early indication of hepatic encephalopathy. Have pt "stop traffic" with hand-- involuntary flapping is a positive sign. Bruising/bleeding tendancies may develop as a result of impaired clotting factors and squestration of PLTs in the spleen. |
|
late sx of bowel obstruction |
Absent bowel sounds: indicative of paralytic ileus or diminshed perfusion indicating a closed bowel lumen (complete bowel obstruction) |
|
Mid epigastric and RUQ discomfort ... what increases suspicion that the pt is having s/s of cholecystitis? What are the s/s? What is it? |

It is an inflammation of the gallbladder. |

|
Painless dark red urine caused by these foods |
Beets, rhubarb, blackberries, several medications (not blackberries though) |
|
38 week gestation triaging with onset of spontaneous bright red painless vag bleed. Most likely cause is? |
Placenta previa. Placenta is abnormally implanted in the lower uterine segment. May partially or completely cover the cervical os... as trhe cervis dilates, the placenta may be torn and bleeding will be bright red vs dark blood assoc. w/ abruption. Early dilation may not be felt by pt, which is why it is painless. |
|
Placental abruption |
premature separation of the normally implanted placenta from the uterine wall. Painful. Classic s/s: vag bleeed dark red, uterine tenderness, abd. pain, back pain, uterine hyperactivity w/ poor relaxtion between contractions. May be vague or severe presentation. |
|
uterine rupture |
can also be severe and acute. injury involving sudden deceleration, severe abd. compression, or direct force to the abd can result in uterine rupture. |
|
When should the RN prepare for a d&c? |
oNGOING BRIGHT RED BLEEDING WITH TISSUE PRESENT & CRAMPING The pt needs D&C if bleeding does not decreased.. She is at high risk for hypovolemia and coagulopathy is bleeding continues. Darkening of blood indicates that it isn't fresh bleeding FYI...even w/ occasional clots. |
|
interventions for renal calculi |
analgesics for pain antiemetics may be necessary fluids to flush it out |
|
Pt w hx of PID pelvic inflamm. disease... RLQ pain, scant vag bleeding, dizziness, pain radiating to L shoulder. 88/50, 127bpm, 22RR, 36.4C, +Hcg. What is most likely? |
Ectopic pregnancy. PID may lead to scarring of the fallopian tubes, which can make it difficult for a fertilized ovum to move into the uterus. Tube can rupture and cause severe bleeding in the peritoneum. Blood irritating the diaphragm causes pain radiating to L shoulder (Kehr's sign) |
|

s/p blunt force chest trauma from rollover, pt has sudden onset of anxiety, diminished breath sounds on one side, tracheal deviation and hypoTN .... this is s/s associated with a rapid |
increase in intrathoracic pressure. most likely a tension penumo. shifts lung/cardiac tissue to uninjured side & decreaseed vent filling and CO. Impedes venous return, shifts mediastinum and depresses diaphragm causing distortion of the great vessels and ressults in decreased CO |
|
Sellick maneuver indication (cricoid pressure) |

use padding, keep it visible, tighten high enough to compleetely occlude arteries and arterioles, a wide TQ and padding, remove ASAP p bleeding controlled. |
|
early s/s hypovolemic shock in adults |
gradual increase in rate/depth of resp. Tachpynea to decrease Co2 and compensate for cellular acidosis since inadequate circulating volume causes cellular hypoxia and anaerobic cellular metabolism. |
