• Increase the serum digoxin sensitivity level
• Decrease the serum digoxin sensitivity level
• Not have any effect on the serum digoxin sensitivity level
• Cause a low average serum digoxin sensitivity level
• Headaches

When a client first takes a nitrate, the nurse expects which symptom that often occurs?

• Nausea and vomiting
• Headaches
• Stomach cramps
• Irregular pulse rate
• Decrease heart rate and decrease myocardial contractility.

The nurse acknowledges that beta blockers are as effective as antianginals because they do what?

• Increase oxygen to the systemic circulation.
• Maintain heart rate and blood pressure.
• Decrease heart rate and decrease myocardial contractility.
• Decrease heart rate and increase myocardial contractility.

• The beta blocker should NOT be abruptly stopped; the dose should be tapered down.

The health care provider is planning to discontinue a client's beta blocker. What instruction should the nurse give the client regarding the beta blocker?

• The beta blocker should be abruptly stopped when another cardiac drug is prescribed.
• The beta blocker should NOT be abruptly stopped; the dose should be tapered down.

• To block the beta1-adrenergic receptors in the cardiac tissues

The beta blocker acebutolol (Sectral) is prescribed for dysrhythmias. The nurse knows that what is the primary purpose of the drug?

• Client stating that pain is 0 out of 10

A nurse is monitoring a client with angina for therapeutic effects of nitroglycerin. Which assessment finding indicates that the nitroglycerin has been effective?

• Client stating that pain is 0 out of 10
• Chest pain

The nurse is monitoring a client during IV nitroglycerin infusion. Which assessment finding will cause the nurse to take action?

• Blood pressure 110/90 mm Hg

• "I can take up to five tablets at 3-minute intervals for chest pain if necessary."

Which statement made by the client demonstrates a need for further instruction regarding the use of nitroglycerin?

• "If I get a headache, I should keep taking nitroglycerin and use Tylenol for pain relief."
• "I should keep my nitroglycerin in a cool, dry place."
• "I should change positions slowly to avoid getting dizzy."
• "I can take up to five tablets at 3-minute intervals for chest pain if necessary."

• "It's best to keep it in its original container away from heat and light."

• "It's best to keep it in its original container away from heat and light."
• "You can put a few tablets in a resealable bag and carry it in your pocket."
• "It's best to lock them in the glove compartment to keep them away from heat and light."
• "I should sit or lie down after I take a nitroglycerin tablet to prevent dizziness."
