1. Right Answer: D
Explanation: (A) Diabetes mellitus is not a common complication of myocardial infarction. (B) Anaphylactic shock is an allergic reaction. (C) Cardiac hypertrophy is a late potential complication. It is a common complication of congestive heart failure. (D) Myocardial infarction causes tissue damage, which may interrupt electrical impulses. Myocardial irritability results from lack of oxygenated tissue.
2. Right Answer: C
Explanation: (A) Intake and output are not laboratory tests. (B) Serum calcium levels are not affected by digoxin or furosemide. (C) Furosemide is a nonpotassium-sparing loop diuretic. Hypokalemia is a common side effect of furosemide and may enhance digoxin toxicity. (D) Serum magnesium levels are not affected by digoxin or furosemide.
3. Right Answer: C
Explanation: (A) Furosemide is a loop diuretic. (B) Nitroglycerin is a vasodilator. (C) Lidocaine is the drug of choice to treat ectopic ventricular beats. (D) Digoxin slows down the electrical impulses and increases ventricular contractions, but it does not rapidly correct ventricular ectopy.
4. Right Answer: D
Explanation: (A) 0.5 ng/mL of digoxin is a subtherapeutic level, not a toxic one. (B) 1.0 ng/mL is a therapeutic level. (C) 2.0 ng/mL is a therapeutic level. (D) Digoxins therapeutic level is 0.82.0 ng/mL. Digoxins toxic level is >2.0 ng/mL.
5. Right Answer: B
Explanation: (A) Fresh vegetables and fruits are excellent sources of essential vitamins. (B) Canned and frozen foods have a high sodium content. Labels of all canned foods should be read to determine if sodium is used in any form. (C) Bread, cereal, and rice are excellent sources of carbohydrates. (D) Fish is an excellent source of protein.
