ATI LPN Pharmacology Quiz Questions
Extract:
Question 1 of 5
The client asks the nurse which type of diabetes is caused by no insulin secretion by the pancreas. What is the best response by the nurse?
Correct Answer: D
Rationale: Type 1 diabetes is caused by autoimmune destruction of pancreatic beta cells, resulting in no insulin secretion, requiring insulin therapy. Type 2 diabetes involves insulin resistance and relative deficiency, not a complete lack of insulin. The other options misrepresent the pathophysiology of diabetes types.
Question 2 of 5
A nurse is preparing to administer diazepam 3 mg IM. The amount available is diazepam for injection 5 mg/mL. How many mL should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: 0.6
Rationale:
To calculate the volume, use: Volume (mL) = Dose (mg) ÷ Concentration (mg/mL). Given a dose of 3 mg and concentration of 5 mg/mL, Volume = 3 ÷ 5 = 0.6 mL, rounded to the nearest tenth as instructed.
Question 3 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 4 of 5
Drug therapy of tuberculosis differs from that of most other infections because:
Correct Answer: C
Rationale: Mycobacteria have a complex, impermeable cell wall, necessitating prolonged treatment with specialized drugs. TB therapy is longer than most infections, patients often have symptoms, and drugs treat both active and latent disease.
Question 5 of 5
The nurse is caring for a client with a diagnosis of urinary tract infection. The physician has ordered an antibiotic. What is the priority prior to administering this medication?
Correct Answer: C
Rationale: A urine culture and sensitivity test identifies the causative bacteria and effective antibiotics, ensuring targeted treatment. Platelet count, blood pressure, and PTT are not priorities for UTI antibiotic administration.
