The primary goal of thrombolytic therapy for ACS is
A. troponin release
B. chest pain relief
C. myocardial reperfusion
D. ectopy prevention - Correct Answer - C. Thrombolytic therapy is
administered to establish and maintain the patency of coronary arteries,
thus improving myocardial perfusion.
A patient with dilated cardiomyopathy is admitted with dyspnea, cough,
palpitations and decreased level of consciousness. The patient is in sinus
tach with no ectopy. The nurse should anticipate management to include
A. administration of captopril (Capoten)
B. insertion of a temporary left ventricular assist device
C. loading the pt with digoxin
D. preparation for dynamic cardiomyopathy procedure - Correct Answer -
A. This pt is showing symptoms of heart failure related to dilated
cardiomyopathy. ACE inhibitors have been effective in improving both
symptoms and survival in these pt. Most pt will tolerate ACE inhibitor
therapy as well.
,Apatient is admitted with acute respiratory failure, left lobar pneumonia and
COPD. Physical examination reveals severe fatigue, coarse inspiratory
crackles and expiratory wheezing. Data also include
HR 132, RR 35, T 102.6 (38.9), pH 7.28, pCO2 72, pO2 48, HCO3 36
Based on this information, the nurse should anticipate which of the
following additional clinical findings
A. purulent sputum
B. mediastinal shift to the right
C. bradypnea
D. intermittent apneic periods - Correct Answer - A. Pneumonia is
common in pt with COPD. Sputum becomes purulent over time in pt with
pneumonia.
A pt with end-stage renal disease asks the nurse why is anemic. The nurse
explains the anemia is caused by
A. blood loss in the urine
B. renal insensitivity to vitamin A
C. inadequate production of erythropoietin
D. inability of the kidney to retain iron. - Correct Answer - C. As chronic
kidney disease progresses to stage 2 and 3, erythropoietin production
decreases and anemia may become clinically evident
A pt is receiving milrinone therapy should be assessed for which of the
following side effects
A. hyperkalemia
B. chest pain
C. thrombocytopenia
,D. decreased urination - Correct Answer - B. Chest pain, ventricular
dysrhthmias and hypotension are potential side effects of milrinone
administration. Thrombocytopenia is a side effect of inamnirone, another
PDI but not milrinone.
Which of the ff ABG results should the PCU nurse anticipate in caring for a
pt. with chronic alcohol abuse
pH pCO2HCO3
A. 7.35 36 18
B. 7.30 50 23
C. 7.50 30 25
D. 7.48 47 32 - Correct Answer - A. Pt with chronic alcohol abuse are at
risk for developing metabolic acidosis, which is reflected with these ABG.
This condition has been termed alcoholic ketoacidosis (AKA) as a distinct
syndrome. AKA is characterized by metabolic acidosis with an elevated
anion gap, elevated serum ketone levels and a normal or low glucose
concentration
A patient reports severe nonradiating substernal chest pain. ECG reveals a
2 mm ST segment elevation in the precordial leads. After pain relief is
achieved with nitroglycerin, the ECG returns to normal. Which of the
following data is most useful in the acute management of this patient.
A. troponin I
B. serum electrolytes
C. coagulation studies
D. lipid profile - Correct Answer - A. This pt is demonstrating symptoms of
ACS. In order to determine if cardiac damage has occurred, troponin levels
, are obtain. When myocardial cells become damaged, troponin levels will
begin to rise in the bloodstream. Determination of the presence of
myocardial damage will help guide pt care management.
Which electrolyte imbalance most commonly accompanies acute tubular
necrosis
A. hyponatremia
B. hypokalemia
C. hypophosphatemia
D. hypouricemia - Correct Answer - A. ATN is characterized by the
kidneys' inability to conserve sodium, so pt will be hyponatremic
A pt is admitted for evaluation of exercise intolerance, increasing short of
breath and a new-onset mitral murmur. Assessment reveals a QT segment
of 0.46 second. The nurse should recognize that the pt is at most risk for
development of
A. atrial fib
B. 2nd degree HB II
C. ventricular dysrhythmia
D. paroxysmal atrial tachycardia - Correct Answer - C. Pt with QT
prolongation are at risk for development of torsades de pointes or
polymorphic vtach. This pt QT interval is prolonged.
A patient develops chest pain, shortness of breath and coughing 3 days
after STEMI. The nurse should suspect
A. Pneumothorax
B. aortic dissection
