Acts as a platelet aggregate inhibitor

• Ibuprofen

• Heparin

• Lovenox

• Aspirin

Answer explanation

Aspirin works by blocking or inhibiting an enzyme that causes platelets to clump together or aggregate.

_____ is caused by a mechanical obstruction that prevents an adequate volume of blood filling the chambers.

• Septic shock

• Distributive shock

• Cardiogenic shock

• Obstructive shock

Answer explanation

Common examples of obstructive shock are cardiac tamponade, tension pneumothorax, and pulmonary embolism.

A medication that blocks receptor sites and prevents other medications from binding to it

• Platelet aggregate inhibitor

• Antagonist

• Blocker

• Agonist

Answer explanation

Antagonists bind to specific receptors which blocks the receptor from producing a desired response. In other words, antagonists work against the receptor and do not allow that receptor to continue what it was doing.

_____ results when there is widespread dilation of small arterioles and/or small venules.

• Hypovolemic shock

• Distributive shock

• Pulmonary shock

• Cardiogenic shock

Answer explanation

Distributive shock causes the circulating blood volume to pool in the expanded vascular beds. There are 4 types of distributive shock:

1.) septic shock

2.) neurogenic shock

3.) anaphylactic shock

4.) psychogenic shock

Nitroglycerin is a _____ which means that it _____ or relaxes the walls of blood vessels.

• vasodilator; dilates

• antihistamine; constricts

• vasodilator; constricts

• blood thinner; dilates

Answer explanation

Nitroglycerin is a nitrate that relaxes or vasodilates the blood vessels. The relaxation of the blood vessels allows for more blood and oxygen to get to heart while lessening the work load.

_____ occurs when there is an inadequate amount of fluid or volume in the circulatory system.

• Hypovolemic shock

• Cardiogenic shock

• Anaphylactic shock

• Hypervolemic shock

Answer explanation

Hypovolemic shock results from severe loss of fluids. Hemorrhagic shock is a type of hypovolemic shock that is a result of the loss of a lot of blood.

What does CPR stand for?

• Cardiopulmonary resuscitation

• Carotid pulse return

• Cardiopreliminary resuscitation

• Coronary pneumo resuscitation

Unintended effects that occur after taking a medication are called

• Allergy

• Contraindications

• Indications

• Adverse effects

Answer explanation

Adverse effects are side effects that can happen after medication administration.

_____ develops when the heart cannot maintain sufficient output to meet the demands of the body.

• Cardiac arrest

• Cardiogenic shock

• Distributive shock

• Obstructive shock

Answer explanation

Cardiogenic shock is caused by inadequate function of the heart or heart failure. The heart must have sufficient cardiac output. Cardiac output is dependent on several factors:

1.) adequate strength for the heart muscles to relax (myocardial contractility)

2.) adequate amount of blood to pump (preload)

3.) resistance to flow in peripheral circulation must be appropriate

What route of administration has the fastest onset?

• Intravenous

• Intradermal

• Sublingual

• Oral

Answer explanation

Medications given via intravenous or IV have the fastest onset of action because the medication goes straight to the blood stream.
