Which nursing diagnosis is appropriate for a patient who has just been administered a sedative-hypnotic drug?
Imbalanced nutrition
Deficient knowledge
Risk for injury and falls
Risk for infection
Sedative-hypnotic drugs cause central nervous system depression, putting the patient at risk for injury and falls.
A patient is admitted to the emergency department after taking an overdose of a barbiturate 15 minutes before arrival. The nurse can anticipate that which drug will be prescribed?
Flumazenil (Romazicon)
Ipecac syrup
Naloxone (Narcan)
Charcoal (Activated charcoal)
There is no antidote for barbiturates. The use of activated charcoal binds to the drug in the stomach and gastrointestinal tract, preventing absorption.
A patient is admitted to the hospital with a diagnosis of benzodiazepine overdose. The nurse anticipates the health care provider will prescribe which antidote for benzodiazepine overdose?
Naltrexone (ReVia)
Nalmefene (Revex)
Flumazenil (Romazicon)
Naloxone (Narcan)
Flumazenil is the antidote for benzodiazepine overdose. The other options are only effective against opioid agonist effects.
The health care provider prescribes dantrolene (Dantrium) to a patient immediately after surgery. The nurse is aware this medication is used to treat what condition?
Delirium tremens
Malignant hyperthermia
Tonic-clonic seizure
Respiratory arrest
Dantrolene is a direct acting skeletal muscle relaxant and is the drug of choice to treat malignant hyperthermia, a possible complication of generalized anesthesia.
A patient is admitted to the emergency department after taking an overdose of a barbiturate 15 minutes before arrival. The nurse can anticipate that which drug will be prescribed?
Naloxone (Narcan)
Charcoal (Activated charcoal)
Ipecac syrup
Flumazenil (Romazicon)
There is no antidote for barbiturates. The use of activated charcoal binds to the drug in the stomach and gastrointestinal tract, preventing absorption.
Which statement is accurate for the nurse to use when teaching a patient the difference between a sedative and hypnotic effect of a drug?
“Sedatives are much stronger than hypnotic drugs and should only be used for short periods of time.”
“Whereas sedative drugs induce sleep, hypnotic drugs induce a state of hypnosis.”
“Most drugs produce sedation at low doses and sleep, the hypnotic effect, at higher doses.”
“There really is no difference; the terms are used interchangeably.”
Many drugs have both sedative and hypnotic properties, with the sedative properties evident at low doses and the hypnotic properties demonstrated at larger doses.
