Extract:
Question 1 of 5
The nurse is discharging a client to home with a prescription for clarithromycin (Biaxin). The nurse knows that teaching has been effective when the client states:
Correct Answer: D
Rationale: Completing the full course of clarithromycin ensures the infection is fully treated, preventing resistance. Stopping early risks relapse, smoking and driving are not contraindicated with clarithromycin.
Question 2 of 5
By which routes can insulin be administered? (Select All that Apply.)
Correct Answer: A,D
Rationale: Insulin is commonly administered subcutaneously for routine management and intravenously in emergencies like diabetic ketoacidosis. Intradermal, oral, and topical routes are ineffective due to poor absorption or degradation.
Question 3 of 5
Which of the following stimulates the pancreas to secrete insulin?
Correct Answer: B
Rationale: Hyperglycemia (elevated blood glucose) triggers pancreatic beta cells to secrete insulin to lower glucose levels. Ketoacids result from low insulin, hypoglycemia reduces insulin secretion, and glucagon raises glucose, not directly stimulating insulin.
Question 4 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 5 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: Lipodystrophy refers to a localized loss of fat tissue or a change in the distribution of fat tissue due to repeated injections at the same site. In patients with diabetes mellitus, injecting insulin into the same site repeatedly can lead to lipodystrophy, affecting insulin absorption and glycaemic control. Petechiae are small, red or purple spots due to bleeding under the skin, not typically related to injection sites. Hematoma is a collection of blood from vessel puncture, not a chronic injection issue. Pustules are pus-filled lesions usually from infection, not injection site repetition.
