ATI LPN Pharmacology Quiz Questions
Extract:
Question 1 of 5
The nurse is caring for a client who is being discharged with a prescription for tetracycline. Which of the following statements, if made by the client, demonstrates an understanding of the discharge instructions?
Correct Answer: A
Rationale: Tetracycline causes photosensitivity, increasing sunburn risk, so avoiding sun exposure like a beach vacation is correct. Stopping the medication early risks resistance, pregnancy is contraindicated due to fetal harm, and tanning salon use is unsafe due to UV exposure.
Question 2 of 5
Which hormones that regulate blood glucose levels are secreted by the pancreas? (Select all that apply.)
Correct Answer: A,D
Rationale: Insulin lowers blood glucose by facilitating cellular uptake, and glucagon raises it by promoting glycogenolysis, both secreted by the pancreas. Growth hormone and antidiuretic hormone come from the pituitary, and estrogen from the ovaries, none directly regulating blood glucose from the pancreas.
Question 3 of 5
Which class of antibiotic is associated with cartilage toxicity and rupture of the Achilles tendon?
Correct Answer: A
Rationale: Fluoroquinolones (e.g., ciprofloxacin) are linked to tendonitis and Achilles tendon rupture, particularly in older adults or with corticosteroid use, due to effects on connective tissue. Other classes listed do not have this association.
Question 4 of 5
Before administering cefazolin (Ancef), the nurse checks for a previous allergic reaction to:
Correct Answer: B
Rationale: Cefazolin is a cephalosporin antibiotic with a beta-lactam ring similar to penicillins, posing a risk of cross-reactivity in penicillin-allergic patients. Checking for penicillin allergy is critical. Yeast, macrolides, and sulfonamides have different structures and no significant cross-reactivity with cephalosporins.
Question 5 of 5
A patient who has just been prescribed an incretin enhancer, asks the nurse how it works. The nurse informs the patient that these types of medications:
Correct Answer: B
Rationale: Incretin enhancers (e.g., DPP-4 inhibitors, GLP-1 agonists) amplify incretin hormones, which stimulate insulin secretion from the pancreas in response to meals, aiding glucose control. They don’t increase insulin production, primarily reduce glucagon (a secondary effect), or decrease glucose uptake.
