Using these 2 drugs together allows maximum benefits while minimizing adverse effects.
- A.
N2O + isoflurane
- B.
Sevoflurane + baralyme
- C.
Thiopental + halothane
Correct Answer
A. N2O + isofluraneExplanation
Using N2O and isoflurane together allows for maximum benefits while minimizing adverse effects. N2O is a commonly used inhalation anesthetic that provides analgesia and reduces the amount of isoflurane needed for anesthesia. Isoflurane is a volatile anesthetic that provides general anesthesia and muscle relaxation. By combining these two drugs, the desired level of anesthesia can be achieved with lower doses of isoflurane, reducing the risk of adverse effects such as hypotension or respiratory depression. This combination also allows for a faster induction and recovery from anesthesia.Rate this question:

This combination of drugs may cause airway irritation.
- A.
N2O + isoflurane
- B.
Sevoflurane + baralyme
- C.
Thiopental + halothane
Correct Answer
B. Sevoflurane + baralymeExplanation
The combination of sevoflurane and baralyme may cause airway irritation. Sevoflurane is a volatile inhalation anesthetic, commonly used for general anesthesia. Baralyme is a carbon dioxide absorbent used in anesthesia machines. When sevoflurane is used with baralyme, it can react with the carbon dioxide absorbent to produce degradation products, such as compound A, which can irritate the airways. This can lead to respiratory complications and discomfort for the patient. Therefore, the combination of sevoflurane and baralyme should be used with caution to minimize the risk of airway irritation.Rate this question:

This drug may mimic B12 deficiency (aka - may cause megaloblastic anemia)
- A.
Enflurane
- B.
N2O
- C.
Propofol
Correct Answer
B. N2OExplanation
N2O, also known as nitrous oxide or laughing gas, may mimic B12 deficiency and cause megaloblastic anemia. This is because N2O inhibits the conversion of homocysteine to methionine, leading to decreased methionine synthesis and impaired DNA synthesis. Megaloblastic anemia is characterized by the production of large, immature red blood cells, which can be caused by a deficiency in vitamin B12 or folate. Therefore, N2O can cause similar symptoms to B12 deficiency, such as anemia. Enflurane and propofol do not have this effect.Rate this question:

- A.
Fast onset, slow recovery
- B.
Slow onset, slow recovery
- C.
Fast onset, fast recovery
Correct Answer
C. Fast onset, fast recoveryExplanation
Propofol has a fast onset, meaning it takes effect quickly after administration. This is beneficial for procedures requiring rapid induction of anesthesia. Additionally, propofol has a fast recovery time, allowing patients to wake up quickly and resume normal activities sooner. This is advantageous for minimizing post-operative sedation and reducing the risk of complications associated with prolonged anesthesia.Rate this question:

Describe the onset & recovery time for barbituates.
- A.
Fast onset, slow recovery
- B.
Slow onset, slow recovery
- C.
Fast onset, fast recovery
Correct Answer
A. Fast onset, slow recoveryExplanation
Barbiturates are a type of sedative-hypnotic drugs that act on the central nervous system. They are known to have a fast onset of action, meaning they take effect quickly after administration. This is because they rapidly cross the blood-brain barrier and bind to specific receptors in the brain. However, the recovery time for barbiturates is slow. This is because they are metabolized slowly by the liver and have a long half-life, which means it takes a significant amount of time for the drug to be eliminated from the body. As a result, the effects of barbiturates can linger for a prolonged period, leading to a slow recovery.Rate this question:

The use of ketamine may require premedication.
- A.
Anti-cholinergic drugs
- B.
Benzodiazepines
- C.
Beta blockers
Correct Answer
A. Anti-cholinergic drugsExplanation
The use of ketamine may require premedication with anti-cholinergic drugs. Ketamine is a dissociative anesthetic that can cause excessive salivation, bronchial secretions, and laryngospasm. Anti-cholinergic drugs, such as atropine or glycopyrrolate, can be administered before ketamine to reduce these effects. These drugs block the action of acetylcholine, which helps to decrease secretions and prevent laryngospasm, ensuring a smoother induction and maintenance of anesthesia. Benzodiazepines and beta blockers are not typically used as premedication for ketamine administration.Rate this question:

MOA of propofol
- A.
Blocks Na+ channels
- B.
Enhances GABAa transmission
- C.
GABA agonist
Correct Answer
B. Enhances GABAa transmissionExplanation
Propofol is a sedative-hypnotic medication that enhances the transmission of GABAa (gamma-aminobutyric acid type A) receptors. GABA is an inhibitory neurotransmitter in the central nervous system, and when it binds to GABAa receptors, it produces an inhibitory effect, leading to sedation and anesthesia. By enhancing GABAa transmission, propofol intensifies the inhibitory effects of GABA, resulting in sedation and anesthesia. This explains why propofol is commonly used for inducing and maintaining anesthesia during surgical procedures.Rate this question:

The MAC for enflurane decreases when coadministered with
- A.
N2O or opiods
- B.
Ketamine
- C.
IV anesthetics
Correct Answer
A. N2O or opiodsExplanation
When enflurane is coadministered with N2O or opioids, the MAC (minimum alveolar concentration) of enflurane decreases. MAC is a measure of the potency of an inhaled anesthetic, and a decrease in MAC indicates that a lower concentration of enflurane is needed to achieve the desired anesthetic effect. The coadministration of N2O or opioids may enhance the anesthetic effect of enflurane, allowing for a reduction in its dosage.Rate this question:

It would be inadvisable to give this drug to a pt with liver failure.
- A.
Enflurane
- B.
Propofol
- C.
Halothane
Correct Answer
C. HalothaneExplanation
Halothane is a volatile inhalation anesthetic that is primarily metabolized by the liver. In patients with liver failure, the liver's ability to metabolize drugs is impaired, leading to a buildup of the drug in the body. This can result in prolonged and exaggerated effects of halothane, increasing the risk of toxicity and adverse reactions. Therefore, giving halothane to a patient with liver failure would be inadvisable to avoid potential harm.Rate this question:
