1. what medication should be given to a patient presenting to the emergency
department with altered level of consciousness, seizures, or both, if a
concern of Wernicke-Korsakoff syndrome exists? - ANSWER Thiamine
(Vitamin B1)
2. psychoactive drugs - ANSWER Chemicals that affect the nervous system
and result in altered consciousness. They can alter our perception, influence
our moods, call me later us down, make us feel more alert
3. Classification of psychoactive drugs - ANSWER Based on the effect they
have in the body. There are 4 groups
Depressants
Hallucinogens
Stimulants
Opiates
4. Depressants - ANSWER reduce activity of CNS, decrease HR, BP, slow
breathing, cause dizziness and lack or coordination and lower our processing
speed which affects how we act and react to the things that are going on
around us
, 5. depressant drugs - ANSWER 1. Barbiturates - tranquilizers help sleep or
calm down; used in anesthesia or anticonvulsant.. have a high addition
potential
Benzodiazepines- tx of insomnia, anxiety, seizures
Alcohol - decrease cognitive control and decrease inhibitions
6. your ICU patient is admitted following multisystem trauma secondary to a
motor vehicle collision. The patient is ventilated and will be maintained on a
neuromuscular blocking continuous agent to maintain neuromuscular
blockage and deep sedation. Which of the following is a true statement -
ANSWER - NMBAs also offer analgesic and sedating properties.
- this is an ideal patient for a succinylcholine continuous infusion
- repair of superficial lacerations can now be accomplished without
further anesthesia since the patient is on an NMBA
- if dantrolene is needed postoperatively on the NMBA, care should be
taken to ensure muscle strength has returned prior to extubation *****
7. which of the following best describes the rationale for long-term methadone
therapy in treating opioid addition and abuse? - ANSWER - methadone has
greater oral bioavailability that morphine
8. what is an example of a pure opioid antagonist that binds competitively to
opioid receptors, does not produce analgesia or opioid side effects, and
reverses the toxic effects of agonist and agonist-antagonist opioids -
ANSWER naloxone (narcan)
9. your patient presents with essential hypertension, and in reviewing lab
results, you note that the circulating plasma renin and catecholamine levels
are high. you decide to lower blood pressure by reducing both cardiac output
and systemic vascular resistance (blocking both alpha and beta-adrenergic
receptors) with a single pharmaceutical agent. which of the following is
most likely to achieve this goal? - ANSWER labetalol (trandate)
