of Pharmacology | Q&A with Rationale

Nursing
1. A nurse is preparing to administer insulin lispro to a client with type 1 diabetes mellitus. At
which time should the nurse plan to administer this medication?
A. 30 to 60 minutes before a meal
B. Immediately after a meal
C. 15 minutes before a meal
D. At bedtime with a snack
Answer: C
Rationale: Insulin lispro is a rapid-acting insulin with an onset of 15 to 30 minutes. It
should be administered 15 minutes before meals to align with postprandial glucose
elevations. Administering it too early may lead to hypoglycemia before the meal is
consumed.
2. A client is prescribed levothyroxine for the treatment of hypothyroidism. Which instruction
should the nurse include in the teaching plan?
A. Take the medication with a full glass of milk.
B. Expect to see full effects within 24 hours.
,C. Discontinue the medication once symptoms improve.
D. Take the medication on an empty stomach in the morning.
Answer: D
Rationale: Levothyroxine should be taken on an empty stomach, typically 30 to 60 minutes
before breakfast, to maximize absorption. Absorption is decreased by food, especially
calcium and fiber. This medication is usually a lifelong therapy and requires consistent
daily dosing.
3. A nurse is teaching a client who has a new prescription for albuterol and beclomethasone
inhalers. Which instruction should the nurse provide?
A. Use the beclomethasone inhaler first, then the albuterol.
B. Use both inhalers at the same time to ensure effectiveness.
C. Only use the albuterol inhaler if the beclomethasone does not work.
D. Use the albuterol inhaler first, then wait 5 minutes before using beclomethasone.
Answer: D
Rationale: The bronchodilator (albuterol) should be used first to open the airways,
followed by the corticosteroid (beclomethasone). Waiting 5 minutes between inhalers
allows the bronchodilation to improve the delivery of the steroid into the lungs. This
sequence maximizes the therapeutic effect of the maintenance medication.
, 4. A client with type 2 diabetes is scheduled for a CT scan with intravenous contrast. The
nurse should notify the provider if the client is taking which medication?
A. Glyburide
B. Metformin
C. Pioglitazone
D. Sitagliptin
Answer: B
Rationale: Metformin must be discontinued 48 hours before and after procedures
involving iodine-based contrast media. Contrast media can cause acute renal failure, which
increases the risk of metformin-induced lactic acidosis. The nurse must monitor renal
function before the client resumes the medication.
5. A nurse is caring for a client receiving long-term prednisone therapy. Which of the
following findings should the nurse monitor for as a potential adverse effect?
A. Hypoglycemia
B. Hypokalemia
C. Weight loss
D. Hypercalcemia
Answer: B
