ATI N211 Pharmacology Exam Questions
Extract:
Question 1 of 5
A nurse is caring for a client who has bipolar disorder and has been taking lithium for 1 year. Before administering the medication, the nurse should check to see that which of the following tests have been completed?
Correct Answer: D
Rationale: Thyroid hormone assay is necessary, as long-term lithium use can cause hypothyroidism. The other tests are not specifically required for lithium monitoring.
Question 2 of 5
A nurse is teaching a client who has been taking prednisone to treat asthma and has a new prescription to discontinue the medication. The nurse should explain to the client to reduce the dose gradually to prevent which of the following adverse effects?
Correct Answer: B
Rationale: Gradual dose reduction prevents adrenocortical insufficiency, as abrupt cessation can impair the body's ability to produce cortisol. Rebound pulmonary congestion, dehydration, and hyperglycemia are not directly related to prednisone discontinuation.
Question 3 of 5
A nurse is calculating the intake of a client during the past 9 hr. The client's intake includes lactated Ringer's IV at 150 mL/hr. cefazolin 2 g IV intermittent bolus in 100 mL of 0.9% sodium chloride. two units of packed RBCs of 275 mL and 250 mL; two IV bolus infusions of 250 mL of 0.9% sodium chloride, famotidine 20 mg IV intermittent bolus in 50 mL of 0.9% sodium chloride. How many mL of intake should the nurse record?
Correct Answer: 2525
Rationale: Calculate: Lactated Ringer's (150 mL/hr × 9 hr = 1350 mL), cefazolin (100 mL), RBCs (275 + 250 = 525 mL), saline boluses (250 × 2 = 500 mL), famotidine (50 mL).
Total = 1350 + 100 + 525 + 500 + 50 = 2525 mL.
Question 4 of 5
A nurse is preparing to administer 09% sodium chloride 1,200 mL IV to infuse over 24 hr. The drop factor of the manual tubing is 15 g/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. De not use a trailing zero)
Correct Answer: 13
Rationale: Calculate: 1200 mL ÷ 24 hr = 50 mL/hr.
Then, 50 mL/hr × 15 gtt/mL ÷ 60 min = 12.5 gtt/min, rounded to 13 gtt/min.
Question 5 of 5
A nurse is preparing to administer 0.45% sodium chloride (NaCl) 1000 mL IV to infuse over 8 hr. The nurse should set the IV pump to deliver how many mL/hr? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero)
Correct Answer: 125
Rationale:
To calculate the infusion rate, divide the total volume (1000 mL) by the infusion time (8 hours): 1000 ÷ 8 = 125 mL/hr.
