A nurse is planning care for a client who is experiencing opioid toxicity. Which of the following medications should the nurse anticipate administering?
Naloxone
Atropine
Midazolam
Dexamethasone
The Correct Answer is A
A) Naloxone: This is the correct medication to anticipate administering for opioid toxicity. Naloxone is an opioid antagonist that competitively blocks opioid receptors, reversing the effects of opioid overdose, including respiratory depression, sedation, and hypotension. Administering naloxone can quickly reverse the toxic effects of opioids and restore adequate ventilation and consciousness in the client.
B) Atropine: Atropine is not indicated for opioid toxicity. It is an anticholinergic medication used to treat bradycardia and to decrease respiratory secretions, but it does not reverse the effects of opioids.
C) Midazolam: Midazolam is a benzodiazepine medication used for sedation, anxiety reduction, and induction of anesthesia. While it may be used as an adjunct in the management of acute agitation or seizures, it is not the primary medication for reversing opioid toxicity.
D) Dexamethasone: Dexamethasone is a corticosteroid medication with anti-inflammatory and immunosuppressive effects. It is not indicated for the treatment of opioid toxicity.

Correct Answer is C
Explanation
A) Increase in bowel function: Propofol is a sedative-hypnotic agent commonly used for induction and maintenance of anesthesia and sedation for procedures such as colonoscopies. While propofol may affect gastrointestinal motility, it typically leads to a decrease rather than an increase in bowel function. Therefore, an increase in bowel function would not be an expected adverse effect of propofol administration.
B) Increase in heart rate: Propofol generally has a depressant effect on the cardiovascular system, leading to a decrease rather than an increase in heart rate. It causes vasodilation and can result in hypotension and bradycardia, especially during induction of anesthesia. Therefore, an increase in heart rate would not be an expected adverse effect of propofol administration.
C) Decrease in respiratory rate: Respiratory depression is a well-known adverse effect of propofol. It acts as a potent central nervous system depressant, leading to dose-dependent respiratory depression. This effect is more pronounced when propofol is used for deeper levels of sedation or anesthesia. Therefore, monitoring for a decrease in respiratory rate is essential during and after propofol administration to prevent hypoxemia and respiratory compromise.
D) Decrease in body temperature: Propofol infusion syndrome (PRIS) is a rare but potentially fatal complication associated with prolonged high-dose propofol administration. Among its manifestations are metabolic acidosis, rhabdomyolysis, hyperlipidemia, and ultimately, multi-organ failure. However, a decrease in body temperature is not a characteristic feature of PRIS. Instead, hyperthermia or an increase in body temperature may occur as part of the syndrome. Therefore, monitoring for a decrease in body temperature is not a typical adverse effect of propofol administration.
Correct Answer is ["324"]
Explanation
Here’s the calculation to find the filgrastim dosage the nurse should administer per day:
Client weight conversion:
We need the weight in kilograms (kg) for dosage calculation.
Conversion factor: 1 kg = 2.205 pounds
Client weight (kg) = 143 lb / 2.205 lb/kg = 64.86 kg (round to two decimal places for accuracy)
Dosage calculation:
Prescribed dosage: 5 mcg/kg/day
Client weight (kg): 64.86 kg (rounded value from step 1)
Daily filgrastim dose (mcg) = Dosage (mcg/kg/day) x Client weight (kg)
Daily filgrastim dose (mcg) = 5 mcg/kg/day * 64.86 kg = 324.3 mcg (round to nearest whole number as requested)
Therefore, the nurse should administer approximately 324 mcg of filgrastim per day.
