Question 1 of 5
A nurse is preparing to administer lactated Ringer's (LR) 1,000 mL IV to infuse over 8 hr. The drop factor of the manual IV tubing is 10 gtt/mL. The nurse should set the manual IV infusion to deliver how many gtt/min? (Round the answer to the nearest whole number).
Correct Answer: A
Rationale:
To calculate the IV infusion rate in gtt/min: 1000 mL / 480 min 10 gtt/mL = 20.83 ≈ 21 gtt/min.
Therefore, the correct answer is A.
Choice B (20 gtt/min) is incorrect because the calculation results in 20.83 gtt/min, rounded to 21.
Choices C (25 gtt/min) and D (18 gtt/min) are incorrect as they are not the closest whole number approximation to the calculated value.
Question 2 of 5
A nurse is preparing to administer ampicillin 500 mg in 50 ml of dextrose 5% in water (D5W) to infuse over 15 min. The drop factor of the manual IV tubing is 10 gtt/mL. How many gtt/min should the nurse set the manual IV infusion to deliver? (Round to the nearest whole number)
Correct Answer: A
Rationale:
To calculate the IV flow rate, you multiply the drop factor (10 gtt/mL) by the volume to be infused per minute (50 mL / 15 min). This gives you 10 gtt/mL 50 mL / 15 min = 33.33. Rounding to the nearest whole number, the nurse should set the manual IV infusion to deliver 33 gtt/min.
Choice B (66 gtt/min) is incorrect as it is the result of doubling the correct answer.
Choice C (10 gtt/min) is incorrect as it only considers the drop factor without accounting for the volume to be infused.
Choice D (14 gtt/min) is incorrect as it miscalculates the infusion rate based on the given information.
Question 3 of 5
A nurse on a medical unit is preparing to administer alendronate 40 mg PO for an older adult client who has Paget's disease of the bone. Which of the following actions should be the nurse's priority?
Correct Answer: A
Rationale: The correct answer is to administer the medication to the client before breakfast in the morning. Alendronate should be taken on an empty stomach before breakfast to ensure optimal absorption.
Choice B is incorrect because assisting the client to a chair is not directly related to the administration of alendronate.
Choice C is incorrect as there is no specific requirement to avoid taking alendronate with milk.
Choice D is also incorrect as the priority at this moment is the correct administration of the medication in the hospital setting.
Question 4 of 5
A nurse is reviewing laboratory values for a client who reports fatigue and cold intolerance. The client has an increased thyroid stimulating hormone (TSH) level and a decreased total T3 and T4 level. The nurse should anticipate a prescription for which of the following medications?
Correct Answer: C
Rationale: Levothyroxine is the correct answer. In this scenario, the client's elevated TSH and decreased T3 and T4 levels indicate hypothyroidism, a condition where the thyroid gland does not produce enough hormones. Levothyroxine is a synthetic form of thyroid hormone that is used to replace or supplement the body's naturally produced thyroid hormones. Methimazole and Propylthiouracil are used to treat hyperthyroidism by reducing the production of thyroid hormones. Somatropin is a growth hormone used to treat growth hormone deficiency and other conditions unrelated to thyroid disorders.
Question 5 of 5
A nurse is providing teaching to a client who has cirrhosis and a new prescription for lactulose. The nurse should instruct the client that lactulose has which of the following therapeutic effects?
Correct Answer: D
Rationale: The correct answer is D: Reduces ammonia levels. Lactulose is used to reduce blood ammonia levels in clients with hepatic encephalopathy. Options A, B, and C are incorrect because lactulose does not have the therapeutic effect of increasing blood pressure, preventing esophageal bleeding, or decreasing heart rate.
