ANSWERS | COMPREHENSIVE REVIEW | UPDATED VERSION
1. Describe the mechanism by which heparin-induced thrombocytopenia (HIT)
affects platelet levels in the body.
HIT occurs when antibodies form against heparin-platelet factor 4
complexes, leading to platelet activation and consumption.
HIT is a result of increased blood viscosity due to heparin
administration.
HIT results from the direct inhibition of platelet synthesis by heparin.
HIT is caused by an increase in platelet production in response to
heparin.
2. Describe why monitoring electrolyte levels is crucial for patients on diuretics.
Monitoring electrolyte levels is only necessary during the first week of
treatment.
Monitoring electrolyte levels is crucial because diuretics can lead
to imbalances, particularly of potassium and sodium, which can
cause serious complications.
Monitoring electrolyte levels is only important for patients with kidney
disease.
Monitoring electrolyte levels is not necessary as diuretics do not
affect them.
3. A patient with a history of myocardial infarction is prescribed medication to
prevent future arterial thrombi. Which medication class would be most
appropriate for this patient?
Antiplatelet agents
, ACE inhibitors
Beta-blockers
Calcium channel blockers
4. What is the effect of drugs that dilate the veins on postural hypotension?
They decrease postural hypotension.
They only affect arterial pressure.
They have no effect on postural hypotension.
They intensify and prolong postural hypotension.
5. What vital sign is particularly important to monitor in patients taking ACE
inhibitors?
Blood pressure
Respiratory rate
Heart rate
Temperature
6. Arterial thrombi is prevented with ____ _.
thrombolytics
anticoagulants
antiplatelets
7. A patient with primary hypertension is prescribed drug therapy for the first
time. The medication prescribed is a calcium channel blocker called
amlodipine/Norvasc. What is the most common adverse effect of this
medication:
, hepatic impairment
tachycardia
peripheral edema
blurred vision
8. A patient experiences dizziness upon standing up quickly. Based on your
knowledge of cardiovascular pharmacology, what condition might this
indicate, and what initial advice would you give to the patient?
Pulmonary embolism; instruct the patient to perform deep breathing
exercises.
Orthostatic hypotension; advise the patient to rise slowly from a
seated or lying position.
Heart failure; suggest immediate bed rest.
Hypertension; recommend increasing fluid intake immediately.
9. What are the two primary classes of medications used to manage elevated
blood pressure?
ACE inhibitors and diuretics
Beta-blockers and calcium channel blockers
Statins and fibrates
Anticoagulants and antiplatelets
10. Which hypertensive would be your first choice for a pregnant patient?
hydrochlorothiazide
carvedilol
perindopril
, methyldopa
11. Choose the factor(s) that make it difficult for many people to adhere to
antihypertensive therapy.
Expense and daily hassle of taking pills
Lack of symptoms of the disease
All of the other answers are correct.
Troublesome drug side-effects
12. A pregnant patient with chronic hypertension is experiencing side effects
from her current medication. What would be an appropriate next step in her
treatment plan?
Discontinue all antihypertensive medications immediately.
Consider switching to Methyldopa if not already prescribed.
Increase the dosage of her current medication.
Prescribe a calcium channel blocker instead.
13. Which should be closely monitored in a patient receiving diuretic
medication:
blood urea nitrogen,
serum electrolytes
CBC,
ABGs,
14. What is the recommended frequency for liver function tests in patients
taking statins?
At baseline and periodically thereafter
