Deck 33: Calcium Channel Blockers

Question 1

The nurse advises a client taking nifedipine (Procardia)to avoid alcohol while taking this drug because this combination increases the risk of:
1)Liver damage.
2)Peptic ulcer.
3)Fainting.
4)Headache.

Answer 1

3

Question 2

A client is taking amlopidine (Norvasc)to treat hypertension and chronic stable angina.Which assessment finding is of greatest concern relative to potential adverse effects of nifedipine for this client?
1)Heart rate 132 beats per minute
2)Respiratory rate 22 breaths per minute
3)Facial flushing
4)Pedal edema 1+

Answer 2

1

Question 3

A client's history includes hypertension and chronic stable angina pectoris.Which drug can manage both conditions?
1)Nicardipine (Cardene)
2)Felopidine (Plendil)
3)Amlopidine (Norvasc)
4)Nimodipine (Nimotop)

Answer 3

3

Question 4

A calcium channel blocker has been prescribed for a client with hypertension.The nurse explains that this drug affects the function of the L-type calcium channel by:
1)Blocking sympathetic input to the cell membrane.
2)Enhancing the action potential along the cell membrane.
3)Competing for calcium receptors on the L-type calcium channel.
4)Changing the shape of the L-type calcium channel.

Question 5

The nurse is caring for a client who has been admitted to the hospital following rupture of an intracranial aneurysm.Nimodipine (Nimitop)is prescribed.Which assessment is most significant based on an understanding of the therapeutic effect of this drug for this client?
1)Observe for dependent edema.
2)Conduct frequent neurological checks.
3)Measure blood pressure every four hours.
4)Auscultate cardiac rate and rhythm.

Question 6

The nurse is teaching a client about the role of calcium in hypertension, and explains that a high concentration of calcium in arterial smooth muscle cells leads to:
1)A decrease in blood pressure.
2)Elevation in blood pressure.
3)Hypercalcemia.
4)Hypocalcemia.

Question 7

A client taking verapamil (Calan)to treat hypertension has gained six pounds in the past three days, and is complaining of shortness of breath, constipation, ankle swelling, flushing, and dizziness.He has been switched from verapamil to nifedipine (Procardia).The nurse understands the rationale for this change is that nifedipine (Procardia)will not cause:
1)Constipation.
2)Dizziness.
3)Heart failure.
4)Flushing.

Question 8

The nurse is caring for a client who is taking digoxin (Lanoxin)and diltiazem (Cardizem).The nurse recognizes which finding as representing an adverse interaction of this combination of drugs?
1)Hypertension
2)Bradycardia
3)Peripheral edema
4)Headache

Question 9

The nurse preparing to administer both a calcium channel blocker and a beta₁ adrenergic blocker to a client with hypertension plans to monitor the client's response based on an understanding that these drugs:
1)Promote calcium influx into vascular smooth muscle.
2)Prevent calcium influx into vascular smooth muscle.
3)Promote urinary excretion of sodium.
4)Block sympathetic impulses in sarcolemma membranes.

Question 10

A beta₁-adrenergic antagonist drug has been added to the regimen of a client with angina pectoris who is taking amlodopine (Norvasc).The nurse identifies which assessment finding as representing a goal of therapy related to a common mechanism of action of both drugs?
1)Flushing
2)Constipation
3)Decreased blood pressure
4)Peripheral edema

Question 11

The nurse is preparing to administer medications, including verapamil (Procardia), a calcium channel blocker, and metoprolol (Lopressor), a beta₁-adrenergic blocker, to a client with hypertension.An entry in the client's record indicates he has developed AV block.The nurse will:
1)Hold verapamil (Procardia), administer metoprolol (Lopressor), and notify the prescriber.
2)Hold metoprolol (Lopressor), administer verapamil (Procardia), and notify the prescriber.
3)Hold both metoprolol (Lopressor)and verapamil (Procardia), and notify the prescriber.
4)Administer both metoprolol (Lopressor)and verapamil (Procardia).

Question 12

Which of the following drugs has can be used to treat cardiac dysrhythmias?
1)Nisoldipine (Nisocor)
2)Nifedipine (Procardia)
3)Amlopidine (Norvasc)
4)Verapamil (Calan)

Question 13

The nurse is assessing a client taking both verapamil and digoxin.Which finding might indicate an adverse interaction of this drug combination?
1)Respiratory rate 42 breaths per minute
2)Pulse rate 51 beats per minute
3)Blood pressure 184/96 mm/Hg
4)Serum potassium 5.6 mEq/L

Question 14

The nurse identifies Injury, risk for as a nursing diagnosis for a client beginning therapy with verapamil (Procardia)who takes carbamazepine (Tegretol)to manage a seizure disorder because this drug combination can result in an increased risk of:
1)Seizures.
2)Ataxia.
3)Hypotension.
4)Confusion.

Question 15

The nurse is preparing to administer an intravenous dose of verapamil (Calan)to a client.Prior to administering this drug, the nurse will: (Select all that apply.)
1)Ask the client to sit in a chair.
2)Administer oxygen by nasal cannula.
3)Attach a cardiac monitor.
4)Obtain emergency resuscitation equipment.

Question 16

The nurse observes that a client admitted for orthopedic surgery also has a diagnosis of atrial fibrillation.Which drug can achieve a therapeutic effect relative to the client's diagnosis of atrial fibrillation?
1)Nifedipine (Procardia)
2)Nicardipine (Cardene)
3)Verapamil (Calan)
4)Isradipine (DynaCirc)

Question 17

A client is taking verapamil (Calan)and simvastin (Zocor).To detect a potential adverse effect of this drug combination, the nurse should instruct the client to call her health care provider if she experiences unexplained:
1)Headache.
2)Muscle pain.
3)Dizziness.
4)Tachycardia.
