Extract:
Question 1 of 5
Which of the following orders would the LPN question in a patient with Type I diabetes?
Correct Answer: B
Rationale: Acarbose is an alpha-glucosidase inhibitor used for Type 2 diabetes to slow carbohydrate absorption, not typically for Type 1 diabetes where insulin is the primary treatment due to the absence of insulin production. Insulin glargine, lispro, and regular are all appropriate for Type 1 diabetes management, providing basal or bolus insulin coverage.
Question 2 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 3 of 5
The nurse is asked why neomycin is given as a bowel prep before GI surgery. The nurse correctly replies that:
Correct Answer: A
Rationale: Neomycin reduces intestinal bacterial load, lowering the risk of postoperative infections during GI surgery. Bacteria can be treated post-surgery if needed, antibiotics aren’t required 4 days prior, and anesthesia doesn’t cause antibiotic resistance.
Question 4 of 5
The nurse needs to monitor a client's blood sugar after administration of insulin regular (Humulin R). When does the nurse expect to assess the client's blood sugar based on the peak action of the medication?
Correct Answer: D
Rationale: Regular insulin (Humulin R) peaks at 2–4 hours, when the risk of hypoglycemia is highest, necessitating blood sugar monitoring. Other time frames correspond to onset (15–30 min) or later duration, not peak effect.
Question 5 of 5
Which term is used to describe the stain of bacteria?
Correct Answer: B
Rationale: Gram-positive describes bacteria retaining crystal violet in Gram staining, indicating cell wall structure. Aerobic refers to oxygen needs, cocci to shape, and Bacillus to a genus, not staining.
