ATI LPN Pharmacology Quiz Questions
Question 1 of 5
A nurse is preparing to administer haloperidol 5 mg IM to a client. Available is haloperidol 50 mg/mL. How many mL should the nurse administer per dose? (Round the answer to the nearest tenth/whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: 0.1
Rationale: The correct answer is 0.1 mL.
To calculate this, first divide the dose needed (5 mg) by the concentration of the medication (50 mg/mL) which equals 0.1 mL. This is the amount the nurse should administer.
Choices other than 0.1 mL are incorrect as they do not accurately reflect the calculation based on the given information.
Question 2 of 5
If injection sites are not rotated regularly, the patient with diabetes mellitus may suffer from which of the following?
Correct Answer: A
Rationale: The correct answer is A: Lipodystrophy. If injection sites are not rotated regularly in diabetes mellitus patients, lipodystrophy can occur due to repeated trauma to the same area, leading to changes in fat distribution. This can affect insulin absorption and lead to erratic blood glucose levels. Petechiae (
B), hematoma (
C), and pustules (
D) are not typically associated with the lack of site rotation in insulin injections. Petechiae are tiny red or purple spots due to bleeding under the skin, hematoma is a localized collection of blood outside of blood vessels, and pustules are small pus-filled bumps on the skin, none of which are directly related to site rotation in insulin injections.
Question 3 of 5
Your patient is allergic to penicillin. He may also have a cross-allergy to which class of antibiotics?
Correct Answer: D
Rationale: The correct answer is D: Cephalosporins. Cephalosporins are structurally similar to penicillin, which can lead to cross-allergies in patients allergic to penicillin. Aminoglycosides (
A), Sulfonamides (
B), and Macrolides (
C) are different classes of antibiotics and do not typically cross-react with penicillin allergies.
Therefore, they are incorrect choices for this scenario.
Question 4 of 5
A nurse is preparing to administer dexamethasone 3 mg PO. Available is dexamethasone 1.5 mg tablets. How many tablets should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: 2
Rationale: The correct answer is 2 tablets. The nurse needs to administer 3 mg of dexamethasone. Since each tablet is 1.5 mg, the nurse should give 2 tablets to achieve the total dose of 3 mg. Other choices are incorrect because administering 1 tablet (
Choice
A) would not provide the full required dose, while choices with more than 2 tablets (
Choices C-G) would exceed the prescribed dose of 3 mg. By choosing 2 tablets, the nurse ensures the accurate and safe administration of the prescribed medication.
Question 5 of 5
Which of the following orders would the LPN question in a patient with Type I diabetes?
Correct Answer: B
Rationale: The correct answer is B: Acarbose. LPN stands for "Licensed Practical Nurse." LPNs are not authorized to administer insulin injections, making choices A, C, and D incorrect. Acarbose is an oral antidiabetic medication that can be administered by LPNs, making it the appropriate choice.
Choices E, F, and G are not provided.
