Q

Possible HF nursing diagnoses?

A
  • fluid volume excess (heart not pumping effectively and fluid builds up in tissues and lungs)
  • impaired gas exchange (lung tissues become congested with fluid, less O2 available for exchange, resulting in decreased tissue oxygenation)
  • decreased cardiac output
  • activity intolerance

Q

Which enzyme test is best post MI or unstable angina?

A

Triponin - it is specific to the heart. Creatinine kinase MB and myoglobin are good to test for if it has been a longer amount of time. they are also not specific to cardio.

Q

Within the scope of an LPN?

A
  • administering meds PO
  • attaching cardiac monitor leads
  • obtaining an ECG
  • data/assessment collection (listening to lung sounds and assessing peripheral edema for stable pt’s)
  • observing a previously taught action for accuracy
  • wound care
  • reinforcing previously taught material
  • foley insertion
  • IV insertions ONLY IF TRAINED AND ONLY IN SOME STATES!
  • SQ administrations/infusions

Q

Not in the cope of an LPN?

A
  • administering high alert meds (anticoagulants, narcotics)
  • administering meds to unstable pt
  • obtaining pt history
  • reviewing meds with pt
  • planning activity levels
  • planning for client care or teaching
  • IV insertion (unless properly trained or in some states)
  • Pt education
20
Q

What is the cough that is sometimes seen in pt’s taking ACE inhibitors caused by?

A

caused by a build-up of bradykinin

21
Q

goal of hypertension meds

A

reduced pt BP to < 140/90

22
Q

What is altaplase?

What is the time limit for administering it?

A

Thrombolytic

6 hours

23
Q

MONA order

A

Oxygen
Aspirin
Nitroglycerin
Morphine

24
Q

coronary arteriography?

Biggest risk?

A

diagnostic cathlab procedure

Risk: bleeding (you would see an elevated HR)

25
Q

PVC’s in an acute MI pt…

A

…Can quickly lead to v tach or v fib. Immediate attention is warranted.

26
Q

PRIORITIZATION: what is the first treatment for Vfib?

A

SHOCK!

27
Q

type of pulse expected with afib?

A

irregularly irregular

28
Q

Crackles in the lungs…?

A

indicate L sided heart failure. May not be life threatening in chronic HF pt, but in other pts it is.

29
Q

how should morphine sulfate be written in a doctor’s order?

A

“morphine” or “morphine sulfate” NOT ms

30
Q

What is morphine used for in pulmonary edema?

A

effect as a venodilator which decreases venous return to the heart and reduces ventricular preload.

31
Q

What should a HF pt who was started on a beta blocker be taught?

A

At first symptoms will get worse, but then they will get better…

32
Q

What duties can a nursing assistant perform (without extra training)?

A
  • monitor and record intake and output
  • measuring vital signs
  • remind pt of something previously taught by the RN
33
Q

What duties can a nursing assistant not perform (non-obvious ones…)

A
  • initiate telemetry
  • perform venipuncture
  • obtaining ECG
34
Q

Triponin level that indicates myocardial injury or infarction?

A

A level of more than 0.20 ng/mL

35
Q

Pt discharge instructions after a cardiac cath?

A
  • leave dressing in place for at least one day
  • heavy lifting and exercise should be avoided for several days
  • a small hematoma or bruise is normal
  • it is not necessary to keep the extremity straight after leaving the hospital
36
Q

Raynauds:
What is it?
Pt teaching?

A
  • vasospasms of the arterioles and arteries of the upper and lower extremities, compromising blood flow to the hands and feet (usually unilaterally).
  • avoid exposure to cold by wearing warm clothes
  • nifedipine (procardia) helps relieve symptoms
  • keep your home at comfortably warm tempurature
  • stress reduction techniques can help prevent s/s
37
Q

desirable HDL cholesterol level?

A

> 40 for women, >50 for men

38
Q

desirable LDL cholesterol level?

A

<100 (for people with a risk for heart disease)

39
Q

desirable total cholesterol level?

A

240 is considered HIGH RISK for heart disease

40
Q

normal sinus rhythm ECG measurements…

  1. Atrial and ventricular rate:
  2. PR interval:
  3. QRS complex:
A

Atrial and ventricular rate: 60-100 beat per minute
PR interval: 0.12 - 2.0 seconds
QRS complex: 0.06 - 0.12 seconds

41
Q
  1. each of the little boxes on the ECG strip represent how much time?
  2. each of the TINY boxes inside the little boxes, represent how much time?
A

1) 0.2 seconds

2) 0.04 seconds

42
Q

What does a VVI pacemaker do?

A
  • it is a ventricular rhythm pace maker that senses when the ventricle is not going to fire and provides pacing at that time. Only picks up slack from the ventricle. Does not fire before every QRS complex
43
Q

BP and HR in a hypothermic pt?

A

decreased HR and decreased BP

44
Q

pt teaching for cath procedure?

A
  • taught to report chest pain or any unusual sensations immediately.
  • may be asked to cough or breathe deeply from time to time during the procedure.
  • informed that a warm, flushed feeling may accompany dye injection and is normal.
  • Because a local anesthetic is used, the client is expected to feel pressure at the insertion site.
45
Q

Sinus dysrhythmia?

Is cardiac output affected?

A
  • normal sinus rhythm except the PP interval is irregular

- CO is not affected

46
Q

long term pt care for a pt with peripheral artery disease

A
  • warmth is contraindicated (d/t possibility of burns)

- focuses on pain management, maintain tissue integrity (nutrition and foot care), peripheral circulation (exercise)
