1. Haldol is a first generation typical antipsychotic and it works best on...
Dementia leading to psychosis
The positive symptoms of schizophrenia (voices and disorganized
thoughts)
The vegetative signs of depression
The negative symptoms of schizophrenia: depression
2. Describe how Norepinephrine contributes to the management of severe
hypotension after fluid replacement.
Norepinephrine acts as a diuretic to reduce blood volume.
Norepinephrine enhances oxygen delivery by increasing respiratory
rate.
Norepinephrine increases blood pressure and cardiac output
through vasoconstriction and myocardial stimulation.
Norepinephrine decreases heart rate to manage hypotension.
3. Describe the role of Haloperidol (Haldol) in managing psychotic symptoms.
Haloperidol (Haldol) is prescribed to treat bacterial infections.
Haloperidol (Haldol) is effective in managing respiratory conditions.
Haloperidol (Haldol) is utilized for pain relief in chronic conditions.
Haloperidol (Haldol) is used to reduce symptoms of psychosis and
enhance behavioral control.
,4. Mechanism of action for albuterol
Stimulates beta2-adrenergic receptors in the lungs, which relaxes
the bronchial smooth muscle, thus causing bronchodilation
Inhibits the release of histamine, preventing allergic reactions in the
respiratory tract.
Blocks leukotriene receptors in the lungs, reducing inflammation and
bronchoconstriction.
Acts as a corticosteroid to suppress the immune response and reduce
airway inflammation.
5. What class of medication does Amlodipine belong to?
Beta blocker
Diuretic
Calcium channel blocker
ACE inhibitor
6. Nifedipine is a L-type calcium channel blocker used to treat hypertension. In
some patients when they first use it they experience some tachycardia. Based
on your knowledge of the location and action of L-type Ca channels, what
actions and response to the drug might explain this?
Nifedipine blocks L-type Ca channels on ventricular muscle to
stimulate firing.
Nifedipine blocks L-type Ca channels on coronary artery vascular
smooth muscle causing myocardial ischemia.
Nifedipine blocks L-type Ca channels on vascular smooth muscle
cells and results in vasodilation, followed by reflex tachycardia.
, Nifedipine blocks L-type Ca channels on the SA node resulting in
tachycardia.
Nifedipine blocks L-type Ca channels on vascular smooth muscle and
results in vasoconstriction, followed by reflex tachycardia
7. Which of the following is/are a therapeutic effect of dopamine?
increases inotropy
vasoconstriction by stimulating alpha receptors
all of these
dilates arteries to the kidneys
8. What is the primary role of beta blockers like metoprolol in the management
of chest pain?
To reduce heart rate and myocardial oxygen demand
To enhance myocardial contractility
To prevent calcium entry into cardiac muscle cells
To inhibit clot formation in coronary arteries
9. Pancuronium is a potent neuromuscular blocking agent. What best describes
the action of a neuromuscular blocker.
Depresses the CNS by inhibiting transmitters in the cerebral cortex.
Decrease anxiety by decreasing CNS excitability.
Act by inhibiting transmission of nerve impulses by binding with
cholinergic receptor sites.
Reverses the effects of benzodiazepines on the CNS.
, 10. Describe the primary therapeutic uses of Fentanyl (Sublimaze) in clinical
practice.
Fentanyl (Sublimaze) is primarily used for pain control and as a
supplement in anesthesia.
Fentanyl (Sublimaze) is used for managing anxiety and depression.
Fentanyl (Sublimaze) is used to treat infections and manage
respiratory conditions.
Fentanyl (Sublimaze) is primarily used for treating cardiovascular
diseases.
11. A patient is receiving Dopamine for the treatment of shock. The nurse
explains to the patient's family that Dopamine is used in shock to:
Decrease venous return to the heart and thereby reduce myocardial
workload
Increase vasoconstriction and thereby increase blood pressure
Improve blood flow to the nephrons and thereby prevent renal failure
Improve myocardial contractility and thereby increase blood
pressure
12. The drug methylprednisolone (Solu-Medrol) is a corticosteroid drug given
for what purpose?
anti-inflammatory agent
prevents or reduces edema of tracheobronchial tree
minimizes possibility of respiratory arrest during allergic reaction
all of the above
