A patient is admitted to the emergency department with an overdose of a benzodiazepine. Which antidote will the nurse expect to administer?

  • Flumazenil (Romazicon)
  • Naloxone (Narcan)
  • Naltrexone (ReVia)
  • Nalmefene (Revex)

A

Flumazenil (Romazicon) is the antidote for benzodiazepine overdoses. Naloxone, naltrexone, and nalmefene are used in opioid or narcotic overdose. Flumazenil (Romazicon) should be used with caution when the patient is known to have an addiction to one of the benzodiazepine drugs because of the possibility of withdrawal seizures that may occur.

2

The nurse is caring for a patient who is taking a barbiturate. Which assessment finding requires immediate action by the nurse?

  • History of a sleep disorder
  • +1 pitting edema of the lower extremities
  • Urinary output of 10 mL/hr
  • Blood pressure of 140/95 mm Hg

C

The patient’s output is insufficient and could result in toxicity. History of sleep disorder, +1 pitting edema, and a blood pressure of 140/95 do not require immediate intervention.

3

The patient has recently been prescribed a benzodiazepine and reports experiencing vivid dreams. What does this symptom indicate?

  • Overdosage of the medication
  • Allergic reaction to the medication
  • Therapeutic effect of the medication
  • Inadequate amount of the medication

C

The benzodiazepine medications are known to delay REM sleep and thus generate vivid dreams. Such a symptom is not indicative of overdosage, an allergic reaction, or inadequate dosage.

4

The patient has recently been prescribed a sedative-hypnotic medication and reports experiencing a “hangover”-type effect upon awakening. What does this symptom indicate?

  • A need to change to a different medication
  • Toxicity level of the medication
  • Allergic reaction to the medication
  • Inadequate amount of the medication

A

Some of the sedative-hypnotic drugs can produce a hangover-type effect; if this occurs, the patient should be changed to a different drug. Such a symptom is not indicative of overdosage, an allergic reaction, or inadequate dosage.

5

The patient is undergoing anesthesia in preparation for surgery. The patient is starting to have difficulty speaking and is losing the sensation of pain. Which anesthesia stage is the patient most likely experiencing?

  • Stage 1
  • Stage 2
  • Stage 3
  • Stage 4

A

Difficulty speaking and loss of the sensation of pain both occur in stage 1 of anesthesia.

6

The patient is receiving triazolam (Halcion) as part of treatment for insomnia. The patient complains of experiencing memory problems. The nurse recognizes this as

  • evidence of an allergic response.
  • an idiosyncratic effect.
  • an adverse reaction to the drug.
  • evidence of drug toxicity.

C

Memory issues may occur as an adverse reaction to triazolam (Halcion).

7

The patient is receiving anesthesia in preparation for surgery. The patient will be in which stage of anesthesia when the procedure occurs?

  • Stage 1
  • Stage 2
  • Stage 3
  • Stage 4

C

Once the patient is anesthetized, the procedure will actually occur while the patient is in stage 3 of anesthesia.

8

The patient is undergoing anesthesia in preparation for a procedure. The patient is experiencing hallucinations and dreams. Which anesthesia stage is the patient most likely experiencing?

  • Stage 1
  • Stage 2
  • Stage 3
  • Stage 4

A

During stage 1 of anesthesia, the patient may experience dreams and both auditory and visual hallucinations.
