1.
A client is admitted to the medical intensive care unit with a diagnosis of myocardial infarction. The client's
history indicates the infarction occurred ten hours ago. Which laboratory test result should the nurse expect
this client to exhibit?
A) Elevated LDH.
Feedback: INCORRECT
B) Elevated serum amylase.
Feedback: INCORRECT
C) Elevated CK-MB.
Feedback: CORRECT
D) Elevated hematocrit.
Feedback: INCORRECT
Feedback: INCORRECT
The cardiac isoenzyme CK-MB (C) is the most sensitive and most reliable indicator of myocardial damage
of all the cardiac enzymes. It peaks within 12 to 20 hours after myocardial infarction (MI). (A) is a cardiac
enzyme that peaks around 48 hours after an MI. (B) is expected with acute pancreatitis. (D) would be
expected in a client with a fluid volume deficit, which is not a typical finding in MI.
Points Earned: 0.0/1.0
Correct Answer(s): C

2.
A client reports unprotected sexual intercourse one week ago and is worried about HIV exposure. An initial
HIV antibody screen (ELISA) is obtained. The nurse teaches the client that seroconversion to HIV positive
relies on antibody production by B lymphocytes after exposure to the virus. When should the nurse
recommend the client return for repeat blood testing?
A) 6 to 18 months.
Feedback: INCORRECT
B) 1 to 12 months.
Feedback: INCORRECT C)
D)
, NURSING EXAM TEST
Feedback: INCORRECT
Although the HIV antigen is detectable approximately 2 weeks after exposure, seroconversion to HIV
positive may take up to 6 to 12 weeks (D) after exposure, so the client should return to repeat the serum
screen for the presence of HIV antibodies during that time frame. (A) will delay treatment if the client tests
positive. (B and C) may provide inaccurate results because the time frame maybe too early to reevaluate the
client.
Points Earned: 0.0/1.0
Correct Answer(s): D
3.
The nurse should be correct in withholding a dose of digoxin in a client with congestive heart failure
without specific instruction from the healthcare provider if the client's
A) serum digoxin level is 1.5.
Feedback: INCORRECT B)
C) serum potassium level is 3.
Feedback: CORRECT
D) apical pulse is 68/min.
Feedback: INCORRECT
Feedback: INCORRECT
Hypokalemia (C) can precipitate digitalis toxicity in persons receiving digoxin which will increase the
chance of dangerous dysrhythmias (normal potassium level is 3.5 to 5.5 mEq/L). The therapeutic range for
digoxin is 0.8 to 2 ng/ml (toxic levels= >2 ng/ml); (A) is within this range. (B) would not warrant the nurse
withholding the digoxin. The nurse should withhold the digoxin if the apical pulse is less than 60/min (D).
