Lilley: Pharmacology and the Nursing Process, 10th Edition
MULTIPLE CHOICE
1. The nurse is reviewing discharge teaching for a patient who wi ll be taking
digoxin therapy. The nurse will teach the patient to avoid which foods
when taking the digoxin?
a. Leafy green vegetables
b. Dairy products
c. Grapefruit juice
d. Bran muffins
ANS: D
Bran, in large amounts, may decrease the absorption of oral digitalis
drugs. The other foods do not affect digoxin levels.
DIF: Cognitive Level: Understanding (Comprehension)
TOP: Nursing Process: Implementation
MSC: NC LEX: Physiological Integrit y: Pharmacological and
Parenteral Therapies
2. In assessing a patient before admini stration of a cardiac gl ycoside, the
nurse knows that which lab result can increase the toxicit y of the drug?
a. Potassium level 2.8 mEq/L
b. Potassium level 4.9 mEq/L
c. Sodium level 140 mEq/L
d. Calcium level 10 mg/dL
, ANS: A
Hypokalemia increases the chance of digi talis toxicit y. The other levels
listed are incorrect.
DIF: Cognitive Level: Anal yzing (Anal ysis)
TOP: Nursing Process: Assessment
MSC: NC LEX: Physiological Integrit y: Pharmacological and
Parenteral Therapies
3. The nurse administering the phosphodiesterase inhibitor milrinone
recognizes that this drug will have a positive inotropic effect. Which
result reflects this effect?
a. Increased heart rate
b. Increased blood vessel dilation
c. Increased force of cardiac contractions
d. Increased conduction of electrical impulses across the heart
ANS: C
Positive inotropic drugs increase m yocardial contractilit y, thus
increasing the force of cardiac conduction. Positive chronotropic drugs
increase the heart rate. Positive dromotropic drugs increase the
conduction of electrical imp ulses across the heart. Blood vessel
dilation is not affected.
