Extract:
Question 1 of 5
A patient has had an overdose of an intravenous cholinergic drug. The nurse expects to administer which drug as an antidote?
Correct Answer: B
Rationale: Atropine sulfate is the antidote for cholinergic overdose, counteracting excessive muscarinic receptor stimulation.
Question 2 of 5
A nurse is caring for a client who is postoperative following an appendectomy and is prescribed Ds lactated Ringer's at 150 mL/hr by continuous IV infusion for 12 hr. The drop factor of the manual IV tubing is 20 gtt/mL. The nurse should set the manual IV infusion to deliver how many gtt/min? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: A
Rationale: Using the formula (Volume × Drop factor) / Time = (150 mL × 20 gtt/mL) / 60 min = 50 gtt/min.
Question 3 of 5
While being intubated, a client with a head injury experienced bradycardia. Atropine was consequently administered. What assessment should be postponed until all atropine is excreted and no longer exerting an effect?
Correct Answer: C
Rationale: Atropine can alter brain stem reflexes (e.g., pupillary response, gag reflex), so assessment should be delayed until its effects subside.
Question 4 of 5
A patient has been treated with antiparkinson medications for 3 months. What therapeutic responses should the nurse look for when assessing this patient?
Correct Answer: A
Rationale: Antiparkinson medications improve motor symptoms, enhancing daily living activities.
Question 5 of 5
The drug nalbuphine is an agonist-antagonist (partial agonist). The nurse understands that which is a characteristic of partial agonists?
Correct Answer: A
Rationale: Partial agonists like nalbuphine have a lower dependency potential than full agonists, reducing the risk of physical dependence or tolerance when used for pain management.
