ATI Nurs 112 Fundamentals of Nursing Exam Questions
Question 1 of 5
The physician orders ibuprofen 600 mg po prn for cramping. The medication is supplied in 200-mg capsules. How many capsules will the nurse administer?
Correct Answer: 3
Rationale:
To calculate the number of capsules needed, divide the total dose by the dose per capsule. In this case, 600 mg ÷ 200 mg/capsule = 3 capsules. The correct answer is 3 because it is the exact number of capsules required to achieve the ordered dose. The other choices are incorrect because they do not accurately calculate the correct number of capsules needed based on the prescribed dose and the available dosage strength.
Question 2 of 5
112.2 lb. = _____kg
Correct Answer: 50.9
Rationale:
To convert pounds to kilograms, we use the conversion factor 1 lb = 0.453592 kg.
Therefore, 112.2 lb * 0.453592 kg/lb = 50.9 kg.
Choice A is correct as it correctly calculates the conversion.
Choices B-G are incorrect as they do not use the correct conversion factor or fail to perform the calculation accurately.
Question 3 of 5
Vistaril 75mg IM is ordered for anxiety. Available: 50mg/mL. How many milliliters will the nurse administer?
Correct Answer: 1.5
Rationale:
To determine the correct amount of Vistaril to administer, divide the ordered dose (75mg) by the available concentration (50mg/mL). 75mg ÷ 50mg/mL = 1.5mL.
Therefore, the nurse will administer 1.5 milliliters. Other choices are incorrect because they do not result from the correct calculation process.
Question 4 of 5
The physician orders acyclovir 400 mg po three times a day for herpes. The medication is supplied in 800-mg tablets. How many tablets will the nurse administer?
Correct Answer: 0.5
Rationale: The correct answer is 0.5 tablets.
To administer 400 mg three times a day, the nurse will give 1.5 tablets (800 mg each). Since the tablets are 800 mg, half a tablet (0.5) will equal 400 mg. This ensures the patient receives the correct dose. Other choices are incorrect as they do not consider the tablet strength or the total required dose. Option A (1 tablet) would provide 800 mg per dose, exceeding the required 400 mg. Options B-G do not reflect the necessary dosage calculation.
Question 5 of 5
Mr. Pace receives Atarax 100 mg po at bedtime prn to relieve anxiety. You have 50 mg tablets available. How many tablets will you administer per dose?
Correct Answer: 2
Rationale: The correct answer is 2 tablets per dose. Since Mr. Pace receives 100 mg of Atarax per dose and you have 50 mg tablets available, you would need to administer 2 tablets to achieve the prescribed dose of 100 mg. Splitting the dose into 2 tablets ensures Mr. Pace receives the correct amount of medication to relieve anxiety effectively. Other choices would be incorrect because administering only 1 tablet would not meet the prescribed dose requirement, and administering more than 2 tablets would exceed the prescribed dose, potentially leading to adverse effects.
