Question 1 of 5
A nurse is caring for a client who has a new prescription for metformin. Which of the following laboratory results should the nurse evaluate prior to administering the first dose?
Correct Answer: B
Rationale: Before administering the first dose of metformin, the nurse should evaluate the client's creatinine level. Metformin is primarily excreted by the kidneys, and its clearance depends on renal function. Elevated creatinine levels indicate impaired kidney function, which can lead to metformin accumulation and increase the risk of lactic acidosis.
Question 2 of 5
A nurse is caring for a client who has anxiety and a prescription for oral lorazepam PRN. Which of the following is the correct way to transcribe the prescription into the electronic medical record?
Correct Answer: C
Rationale: The transcription 'Lorazepam 2.5 mg PO every 8 hours as needed for anxiety' correctly reflects the PRN order for anxiety.
Question 3 of 5
A nurse is caring for a client who has a magnesium level of 3.2 mEq/L. Which of the following medications should the nurse expect to administer?
Correct Answer: A
Rationale: Calcium gluconate is the antidote for hypermagnesemia, counteracting the effects of elevated magnesium levels.
Question 4 of 5
A nurse is caring for a client who is receiving neostigmine. Which of the following manifestations should the nurse identify as an adverse reaction to the medication?
Correct Answer: B,C,E
Rationale: Neostigmine's cholinergic effects can cause sweating, respiratory distress (due to bronchoconstriction), and bradycardia (via vagal stimulation).
Question 5 of 5
A nurse discovers that a client has been administered a higher dose of oxybutynin than the prescription indicates. The nurse should assess the client for which of the following adverse effects?
Correct Answer: D
Rationale: Oxybutynin, an anticholinergic, can cause bradycardia due to inhibition of acetylcholine, which regulates heart rate. Assessing for bradycardia is critical after an overdose.
