,1.When administering sublingual nitroglycerin for emergency treatment of angina or
chest pain, the nurse monitors for which common adverse effect?
A. Nausea.
B. Bradycardia.
C. Hypertension.
D. Headache.
Rationale : Headache is a common adverse effect of sublingual nitroglycerin.Headache
may occur in up to 80% of patients who take nitroglycerin, especially during the first few
days of therapy or after an increase in dose5. Headache may be related to the vasodilatory
effects of nitroglycerin, which can cause cerebral vasodilation and increased intracranial
pressure. Headache may also be caused by other factors, such as dehydration, sinusitis, or
migraine. Headache is usually mild to moderate in intensity and can be relieved by
analgesics, such as acetaminophen or aspirin.Headache is not a specific indicator of
nitroglycerin toxicity or overdose
2.The drug URECHOLINE for the management of urinary retention belongs to what
class of drugs?
A. Adrenergic.
B. Anticholinergic.
C. Cholinergic.
D. Adrenergic Blocker.
Rationale: Urecholine is the brand name of bethanechol, a drug that belongs to the class of
cholinergics, genitourinary. It is used to treat urinary retention by stimulating the bladder to contract
and empty.Urecholine can be taken orally or by injection.
3.Which of the following Alpha adrenergic class has a vasodilating effect and can be
used for the management of hypertension?
A. Alpha 3 adrenergic blocker.
B. Alpha 2 adrenergic antagonist.
C. Alpha 1 adrenergic agonist.
D. Alpha 1 Adrenergic Blocking Agents.
Rationale : Alpha 1 adrenergic blocking agents have a vasodilating effect and can be used for the
management of hypertension.They work by preventing the hormone norepinephrine from tightening
2
, the muscles in the walls of smaller arteries and veins, thus lowering the blood pressure.Some
examples of alpha 1 blockers are doxazosin, prazosin, and terazosin.
4.Which laboratory test measures the effectiveness of warfarin?
A. PTT.
B. PT/INR.
C. aPTT.
D. ACT.
Rationale : PT stands for prothrombin time, which is a measure of how long it takes the
blood to clot. INR stands for international normalized ratio, which is a way of standardizing
the PT results across different laboratories. Warfarin is a blood thinner that works by
inhibiting the production of vitamin K-dependent clotting factors in the liver. Therefore,
warfarin prolongs the PT and increases the INR.The PT/INR test is used to monitor the
effectiveness of warfarin therapy and adjust the dose accordingly.
5.Which drug class is capable of dissolving blood clots?
A. Salicylates.
B. Antiplatelets.
C. Anticoagulants.
D. Thrombolytic agents.
Rationale : Thrombolytic agents are a classification of drugs that dissolve blood clots by
activating the enzyme plasmin, which breaks down the proteins (fibrins) that form clots. They are
used for serious conditions, such as stroke, pulmonary embolism, or heart attack when the blood flow
needs to be restored quickly.
