cheat sheet sedatives & hypnotics
Here is a high-yield ATI / NCLEX Sedatives & Hypnotics Cheat Sheet tailored for LPN students at Jersey College. I focused on the MOST TESTED ATI concepts, mechanisms, side effects, nursing interventions, and patient teaching you are likely to see on exams.
ATI MOST TESTED: Sedatives & Hypnotics Cheat Sheet
(LPN – Jersey College / ATI / NCLEX Focus)
1. What Are Sedatives & Hypnotics?
Purpose: Depress the central nervous system (CNS) to produce:
Drug Effect | Meaning |
Sedation | Calming effect |
Hypnosis | Sleep induction |
Anxiolysis | Reduce anxiety |
Muscle relaxation | Relax skeletal muscles |
Anticonvulsant | Prevent seizures |
Key ATI concept:
Most sedative-hypnotics enhance GABA, the major inhibitory neurotransmitter in the brain.
Result:
↓ CNS activity → ↓ anxiety → sleep
2. Benzodiazepines (MOST TESTED)
Prototype
Lorazepam (Ativan)
Other Common Drugs
Diazepam (Valium)
Alprazolam (Xanax)
Midazolam (Versed)
Clonazepam (Klonopin)
Temazepam (Restoril)
Mechanism of Action
Enhance GABA neurotransmitter
ATI phrase to remember:
“Benzos increase GABA → CNS depression”
Uses
Use | Example |
Anxiety disorders | Lorazepam |
Insomnia | Temazepam |
Seizures | Diazepam |
Alcohol withdrawal | Diazepam |
Procedural sedation | Midazolam |
MOST TESTED SIDE EFFECTS
Side Effect | Why it matters |
Sedation | Most common |
Respiratory depression | High doses |
Hypotension | IV administration |
Dizziness | Fall risk |
Confusion | Elderly risk |
Dependence | Long term use |
Black Box Risk
Respiratory depression when combined with opioids
ATI often tests this.
Nursing Assessments
Monitor:
Respiratory rate
Blood pressure
Level of consciousness
Fall risk
Signs of overdose
Antidote (VERY TESTED)
Flumazenil
Used for benzodiazepine overdose
ATI question tip:
Rapid reversal → may cause seizures in dependent patients
Patient Teaching
Teach patients:
Avoid alcohol
Do not drive
Take exactly as prescribed
Risk of dependence
Do not stop abruptly
3. Non-Benzodiazepine Hypnotics (Z-Drugs)
Used mainly for insomnia
Drugs
Zolpidem (Ambien)
Zaleplon (Sonata)
Eszopiclone (Lunesta)
Mechanism
Act on benzodiazepine receptor subtype
Result:
Promote sleep
Minimal anxiety effect
Key ATI Facts
Feature | Exam Tip |
Short half life | Less daytime sedation |
Used only for sleep | Not anxiety |
Rapid onset | Take immediately before bed |
Side Effects
Drowsiness
Dizziness
Headache
Sleep walking
Sleep eating
Sleep driving (rare but tested)
Patient Teaching
ATI favorite questions:
Take right before bedtime
Must have 7–8 hours to sleep
Avoid alcohol
Avoid driving
4. Barbiturates
Used less often today due to high overdose risk
Prototype
Phenobarbital
Mechanism
Enhance GABA activity
Stronger CNS depressant than benzodiazepines.
Uses
Seizures
Anesthesia
Sedation
Major ATI Risks
Risk | Reason |
Respiratory depression | CNS suppression |
Hypotension | Vasodilation |
Dependence | High abuse risk |
Fatal overdose | Narrow therapeutic index |
Nursing Monitoring
Monitor:
Respiratory rate
Blood pressure
Sedation level
IV site if given IV
5. Melatonin Receptor Agonists
Drug
Ramelteon (Rozerem)
Mechanism
Stimulates melatonin receptors in the brain
Regulates sleep-wake cycle
Key ATI Point
Not a controlled substance
Low abuse potential
Side Effects
Dizziness
Fatigue
Somnolence
6. Antihistamines Used for Sleep
Common OTC sleep aids.
Examples
Diphenhydramine (Benadryl)
Doxylamine
Side Effects
Effect | Why |
Drowsiness | CNS depression |
Dry mouth | Anticholinergic |
Urinary retention | Anticholinergic |
Confusion | Elderly risk |
7. MOST TESTED Nursing Interventions
Safety Priority
Sedative drugs increase fall risk
Implement:
Bed in lowest position
Assist with ambulation
Fall precautions
Monitor LOC
Monitor Respiratory Depression
Especially with:
IV benzodiazepines
Barbiturates
Combination with opioids
Monitor for Dependence
Signs:
Increased dose requests
Withdrawal symptoms
Long term use
8. ATI Exam Pearls (VERY HIGH YIELD)
1. Antidote for Benzodiazepines
Flumazenil
2. Sedative + Opioid Risk
Major respiratory depression
3. Z-Drugs
Take immediately before sleep
4. Benzodiazepines
Used for:
Anxiety
Seizures
Alcohol withdrawal
5. Barbiturates
Higher overdose risk
9. Quick ATI Comparison Table
Drug Class | Prototype | Key Risk |
Benzodiazepines | Lorazepam | Respiratory depression |
Z-Drugs | Zolpidem | Sleep behaviors |
Barbiturates | Phenobarbital | Fatal overdose |
Melatonin agonist | Ramelteon | Dizziness |
