As a Respiratory Therapist, it will be crucial for you to know and understand all aspects of treating patients who are on the mechanical ventilator. And one of the most important aspects of this is know about all the drugs for mechanical ventilation. Not to mention, you must know this information in Respiratory Therapy school and for the board exams as well.

So to help with that, we put together this study guide that is loaded with practice questions that can help you learn everything you need to know about the drugs for mechanical ventilation. Are you ready to get started?

Drugs for Mechanical Ventilation Practice Questions:

1. What are the 3 types of drugs needed during ventilation?
Neuromuscular blockers, Sedatives, and Analgesics.

2. What are some examples of Neuromuscular blocking agents?
Succinylcholine chloride, Vecuronium, Pavulon, Rocuronium, Atracurium, and Cisatracurium.

3. What is the action of Succinylcholine chloride?
It is an ultrashort-acting depolarizing agent.

4. What are some examples of drugs used for sedation and analgesia?
Lorazepam (Ativan), Midazolam (Versed), Morphine, Dilaudid, Fentanyl, and Propofol.

5. What are Metaproterenol (Alupent) and Albuterol (Ventolin)?
They are short-acting bronchodilators used to reverse acute bronchospasm and are given in 15-30 minute intervals until effective. You may give them with oxygen to increase tissue perfusion.

6. What is Methylprednisone (Solu-medrol)?
It is a corticosteroid used along with bronchodilators to decrease inflammation, acute respiratory failure. It requires 4-5 days of use before it is effective.

7. What is Dexmedetomidine (Precedex)?
It is a sedative, amnesic, and analgesic. It is indicated for short-term sedation of a patient needing mechanical ventilation. The patient can be easily aroused and then return to a sleep-like state. Side effects include nausea, bradycardia, and hypotension.

8. What are Opioids?
They are used to decrease pain in patients with acute respiratory failure that are on the mechanical ventilator. They are given with sedation and paralytics.

9. What is Acetylcholine?
It is an ester that plays a role in the transmission of nerve impulses at synapses and neuromuscular junctions. It is metabolized by the enzyme cholinesterase. Too much or too little of acetylcholine at the motor endplates may lead to muscle blockade.

10. What is Antimemtic?
It is used for preventing nausea and vomiting.

11. What is Anxiolysis?
It is used for diminishing anxiety.

12. What are Barbiturates?
A group of drugs that depresses the central nervous system. They have many adverse effects, including alteration of the respiratory rate, heart rate, blood pressure, and temperature. They are used in seizure disorders and intracranial pressure imbalances.

13. What are Benzodiazepines?
A group of drugs with strong hypnotic and sedative actions. They are used mainly to reduce anxiety and induce sleep.

14. What are Cathartic agents?
Active purgatives used to produce bowel movements.

15. What does Chronotropic affect?
It affects the rate.

16. What are Corticosteroids?
Hormones that are released from the cortex of the adrenal gland. Their potent anti-inflammatory effects make corticosteroids in the treatment of asthma and chronic bronchitis. They are available for intravenous administration as well as inhalation.

17. What are some examples of inhaled steroids?
Dexamethasone (Decadron, Respihaler), beclamerhasone (Beclovent, Vanceril), flunisolide (Aerobid), and tricimcinolone (Azmacort).

18. What are Depolarizing agents?
Drugs that prolong the depolarization phase of muscle contraction, thus rendering the repolarization/depolarization sequence (normal mechanism for muscle movement) impossible and causing muscle blockade. An example is succinylcholine (Anectine, Quelicin).

19. What is Dexmedetomidine (Precedex)?
An intravenous drug that offers anxiolysis and analgesia but respiratory depression.

20. What is Gamma-aminobutyric acid (GABA)?
A major central nervous system inhibitory transmitter that regulates the chloride ion channel and hyperpolarizes the neurons. Once the neurons are hyperpolarized and become resistant to repeated depolarization, sedation results.

21. What is Haloperidol (Haldol)?
A drug for the control of delirium in mechanically ventilated patients.

22. What does inotropic affect?
It affects contraction.

23. What is Nitric oxide?

24. What are nondepolarizing agents?
Drugs that compete with acetylcholine for the receptor sites at the motor endplates, thus blocking the normal action of acetylcholine and causing muscle blockade.

25. What are some examples of nondepolarizing agents?
Vecuronium bromide (Norcuron) and pancuronium bromide (Pavulon).

Drugs that are used to control pain via the central nervous system. Examples are morphine, codeine, meperidine (Demerol, a synthetic compound).

27. What are Parasympatholytic bronchodilators?
Anticholinergic bronchodilators. Drugs that dilate the airways by inhibiting the parasympathetic branch of the autonomic nervous system. Examples are atropine and ipratropium bromide.

28. What is Propofol (Diprivan)?
