Question 1 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 2 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 3 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.
Question 4 of 5
The nurse is admitting a patient to the acute care floor. While obtaining the history, the client tells the nurse she is allergic to penicillin. Which of the following medications, if ordered by the physician, would be safe for this client?
Correct Answer: A
Rationale: The correct answer is A: Erythromycin (E-mycin). This medication is safe for a patient allergic to penicillin because it belongs to a different antibiotic class (macrolide) and does not cross-react with penicillin. Erythromycin is a suitable alternative for patients with penicillin allergies.
Choice B: Piperacillin-tazobactam (Zosyn) and
Choice C: Ampicillin sulbactam (Unasyn) are both penicillin-based antibiotics and should be avoided in patients allergic to penicillin due to the risk of cross-reactivity.
Choice D: Cefazolin (Kefzol) is a first-generation cephalosporin and has a higher likelihood of cross-reactivity with penicillin compared to erythromycin. It should be avoided in patients with a penicillin allergy.
In summary, the key to selecting a safe medication for a patient allergic to pen
Question 5 of 5
The nurse is screening a group of clients. Which client has the greatest risk for developing type 2 diabetes?
Correct Answer: C
Rationale: The correct answer is C, a 55-year-old female who is 20 pounds overweight. This client has the greatest risk for developing type 2 diabetes due to her age, gender, and weight status. Advancing age and being overweight are significant risk factors for developing type 2 diabetes. Women are also at higher risk compared to men.
Choice A is less likely as age and weight are more significant factors than arthritic pain in a young male.
Choice B, a 12-year-old with a normal height to weight ratio, is less likely due to age and weight status.
Choice D, an 8-year-old female who is developmentally delayed, is less likely as developmental delay is not a primary risk factor for type 2 diabetes at this age.
