Question 1 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 2 of 5
The nurse teaches a patient to self-administer his insulin. How can the nurse best evaluate whether the patient understands the instruction?
Correct Answer: D
Rationale: Observing the patient perform insulin administration confirms correct technique and understanding, allowing immediate correction of errors. Feelings, repeating information, or listing steps are less direct assessments.
Question 3 of 5
Mr. Carter has been recently started on an antibiotic, and has developed a rash and pruritis. You suspect an allergic reaction and immediately assess him for other more serious symptoms. What question would be most important to ask Mr. Carter?
Correct Answer: D
Rationale: Difficulty breathing indicates potential anaphylaxis, a life-threatening allergic reaction requiring immediate intervention. Blood in stool, hearing issues, or headaches are less urgent and not specific to severe allergic responses.
Question 4 of 5
Untreated or improperly treated diabetes is the primary cause of the following: (Select All that Apply.)
Correct Answer: B,C,E
Rationale: Diabetes is a leading cause of new blindness (diabetic retinopathy), nontraumatic lower extremity amputations (due to neuropathy and poor circulation), and renal failure (diabetic nephropathy). Pancreatitis and hepatitis are not directly caused by diabetes but have other etiologies like gallstones or viral infections.
Question 5 of 5
The patient with tuberculosis is now on isoniazid (INH). Which laboratory test should the nurse monitor?
Correct Answer: A
Rationale: Isoniazid is hepatotoxic, potentially causing liver damage, so monitoring liver function tests (LFTs) is essential to detect early hepatotoxicity. PT/PTT (clotting), BUN (kidney), and CBC (general health) are not primarily affected by INH.
