Extract:
Question 1 of 5
A nurse is preparing to administer aspirin 650 mg PO every 12 hr. The amount available is aspirin 325 mg tablets. How many tablets should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: B
Rationale:
To calculate the number of tablets: 650 mg (required dose) ÷ 325 mg/tablet (available dose) = 2 tablets. The answer is a whole number, so no rounding is needed.
Question 2 of 5
A nurse is caring for a client who overdosed on morphine and has a respiratory rate of 6/min. Which medication should the nurse plan to administer?
Correct Answer: D
Rationale: Naloxone is the standard treatment for opioid overdose, including morphine. It is an opioid antagonist that binds to opioid receptors in the brain, effectively reversing the effects of opioids and restoring normal respiration.
Question 3 of 5
A nurse is caring for a client who has an infection. The nurse should use which of the following strategies to prevent the transmission of the client's infection?
Correct Answer: D
Rationale: Performing hand hygiene before, during, and after direct contact with the client is the most effective strategy to prevent the transmission of infection.
Question 4 of 5
A client diagnosed with trichomoniasis is prescribed metronidazole (Flagyl). The nurse should instruct the client to avoid which contraindication associated with this medication?
Correct Answer: C
Rationale: Alcohol is a significant contraindication with metronidazole due to the potential for a disulfiram-like reaction. This reaction can cause severe nausea, vomiting, flushing, tachycardia, and shortness of breath.
Question 5 of 5
A client has overdosed on scopolamine (Scopace) while being treated for motion sickness. The nurse recognizes she will administer which reversal medication for an anticholinergic overdose?
Correct Answer: C
Rationale: Physostigmine is an acetylcholinesterase inhibitor that reverses anticholinergic toxicity, such as scopolamine overdose.
