Question 1 of 5
Mrs. Oza, age 69, has hypertension and has one functioning kidney. She loves chocolates and enjoys an alcoholic beverage twice a week. Her hobby is gardening and she goes for long walks despite having arthritis. Which one of the following pieces of information is likely to have the greatest significance if she is prescribed vancomycin?
Correct Answer: C
Rationale: Vancomycin is excreted by the kidneys, and with only one functioning kidney, Mrs. Oza risks drug accumulation and toxicity unless the dose is adjusted. Alcohol, sun exposure, and hypertension are less critical for vancomycin management.
Question 2 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 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
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
A nurse is preparing to administer dexamethasone 3 mg PO. Available is dexamethasone 1.5 mg tablets. How many tablets should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: 2
Rationale:
To calculate the number of tablets, use the formula: Number of tablets = Dose (mg) ÷ Strength per tablet (mg). Given a dose of 3 mg and a tablet strength of 1.5 mg, Number of tablets = 3 ÷ 1.5 = 2 tablets. The answer is a whole number as required.
