36 hours after an anterior STEMI with stent placement in the LAD, a pt develops st
elevation in leads ii, iii, avf. the most likely reason is:
a. these are reciprocal changes
b. newly placed stent is occluded
c. there is a new ischemia in a diff location
d. this is an expected evolution of the MI
- answer-c.
it would be reciprocal changes if there is ST depression not elevation
ii, iii, and avf is located in inferior wall if new stent is occluded, st elevation would
be on the anterior leads which is v2-v4
76-year-old patient is receiving gentamicin and linezolid for an infection. Which of
the following potential complications is the most important for the nurse to
monitor this patient for?
A. Acute delirium
B. Acute kidney injury
C. Acute hepatic failure
D. Sepsis
- answer-B.
Gentamicin is a nephrotoxic agent that places patients at risk for acute kidney
injury, and this risk is increased in older patients. Acute delirium (A), liver failure
(C), and sepsis (D) are all complications that could occur in an older adult with an
infection but would not be caused by the administration of an antibiotic.
A patient shows a new slight facial droop and the patient's right arm is weaker than
the left. A priority intervention would be to
A. Obtain a serum glucose level
B. Obtain a full set of vital signs
C. Initiate the stroke protocol
D. Initiate the code response team
- answer-C.
, The stroke protocol should be activated as soon as signs of stroke are identified in
a patient. Initial signs of stroke include facial droop, arm down drift, and garbled
speech. For best outcomes, the time elapsed between initials signs of stroke and
treatment must be as short as possible.
a patient w history of iv drug abuse develops sudden hypotension, dyspnea, and a
systolic murmur heard at the 5th ics left midclavicular line. the nurse suspects
acute:
a. aortic dissection
b. mitral regurgitation
c. cardiac tamponade
d. ventricular septal defect
- answer-b.
based on pt's history of iv drug abuse and also the location of the murmur
A patient with chronic obstructive pulmonary disease (COPD) is admitted for
worsening dyspnea and possible pneumonia. The current ABG results are pH,
7.19; PaO2, 52 mm Hg; PaCO2, 68 mm Hg; HCO3 - , 32 mmol/L. The nurse
would interpret these results as
A. Metabolic acidosis with hypoxemia
B. Respiratory acidosis with hypoxemia
C. Respiratory alkalosis with typical oxygenation for a COPD patient
D. Metabolic alkalosis with typical oxygenation for a COPD patient
- answer-B.
Based on the ABG analysis, the patient is experiencing a respiratory acidosis with
hypoxemia most likely due to the pneumonia. A pH of 7.19 indicates acidosis; a
PaCO2 of 68 mm Hg is elevated and a cause of acidosis; an HCO3 - of 32 mmol/L
indicates renal compensation; a PaO2 of 52 mm Hg indicates hypoxemia
a patient with hypertrophic cardiomyopathy was just admitted to PCU. you are
reviewing the admission order. which one concern you?
a. oxygen 2L nc, continuous tele
b. beta-blocker and amiodarone
c. chest xray and 2-d echo
d. dig and lasix daily
- answer-d. dig and lasix daily
be careful for + inotropes and diuretics for pt with cardiomyopathy
