ATI N211 Pharmacology Exam I Questions
Extract:
Question 1 of 5
A nurse is preparing to administer 0.9% sodium chloride (NSS) 3000 mL IV to infuse over 24 hr. The drop factor on the manual IV tubing is 10 gtt/mL. The nurse should set the manual IV infusion to deliver how many gtt/min?
Correct Answer: A
Rationale: The correct answer is A: 21 gtt/min.
To calculate the infusion rate, first convert the total volume to mL/hr: 3000 mL / 24 hr = 125 mL/hr.
Then, convert mL/hr to gtt/min using the drop factor: 125 mL/hr x 10 gtt/mL / 60 min/hr = 20.83 gtt/min, which rounds up to 21 gtt/min. This rate ensures the correct administration of NSS over the specified time period.
Choice B is incorrect as it does not accurately calculate the infusion rate.
Choices C and D are also incorrect, as they do not follow the correct calculation method.
Question 2 of 5
A nurse is providing teaching to a client who has hypertension and a new prescription for hydrochlorothiazide. Which of the following instructions should the nurse provide?
Correct Answer: A
Rationale: The correct answer is A: Take the medication early in the day. This is because hydrochlorothiazide is a diuretic that can increase urination, so taking it early can prevent nocturnal urination and sleep disturbances.
B: Weighing weekly is not specific to hydrochlorothiazide; it is a general monitoring practice.
C: Muscle pain is not an expected adverse effect of hydrochlorothiazide.
D: Taking the medication on an empty stomach is not necessary for hydrochlorothiazide.
Question 3 of 5
A nurse is caring for a client who is postoperative hip arthroplasty and has a new prescription for enoxaparin 1 mg/kg/dose subcutaneous every 12 hr. The client weighs 95 lbs. How many mg should the nurse administer per dose?
Correct Answer: A
Rationale: The correct answer is A: 43 mg.
To calculate the dose of enoxaparin for this client, we first need to convert their weight from pounds to kilograms. Since 1 kg is approximately equal to 2.2 lbs, the client's weight of 95 lbs is approximately 43.18 kg. Next, we multiply the weight in kg by the prescribed dose of 1 mg/kg, which gives us 43.18 mg. Since the dose is rounded to the nearest whole number, the correct dose to administer per dose is 43 mg.
Choices B, C, and D are incorrect as they do not accurately calculate the dose based on the client's weight.
Question 4 of 5
A nurse is teaching a client who has a new prescription for captopril. Which of the following instructions should the nurse include in the teaching?
Correct Answer: C
Rationale: The correct answer is C: Monitor for a cough. Captopril, an ACE inhibitor, can cause a persistent dry cough as a side effect. By instructing the client to monitor for a cough, the nurse is addressing a common side effect of the medication.
Choice A is incorrect because captopril does not interact with grapefruit juice.
Choice B is incorrect because captopril can be taken without regard to meals.
Choice D is incorrect because holding the medication for heart rate less than 60/min is not specifically related to captopril.
Question 5 of 5
A nurse is providing teaching to a client who has hypertension and a new prescription for hydrochlorothiazide. Which of the following instructions should the nurse provide?
Correct Answer: A
Rationale: The correct answer is A: Take the medication early in the day. Hydrochlorothiazide is a diuretic that can increase urination frequency. Taking it in the morning helps prevent nocturia, promoting better sleep. Option B is incorrect as weighing weekly is not directly related to monitoring the effect of hydrochlorothiazide. Option C is incorrect because muscle pain is not a common adverse effect of this medication. Option D is incorrect as hydrochlorothiazide should be taken with food to minimize gastrointestinal side effects.
