Extract:
Question 1 of 5
An adult is receiving gentamicin IV q8h. Which laboratory tests does the nurse expect that the client will have done regularly?
Correct Answer: B
Rationale: BUN and serum creatinine are tests of renal function. Gentamicin is nephrotoxic. All persons receiving gentamicin should have these tests done regularly to assess for toxicity.
Question 2 of 5
A post-operative client has a prescription for acetaminophen with codeine. What should the nurse recognize as a primary effect of this combination?
Correct Answer: A
Rationale: Enhanced pain relief. Combination of analgesics with different mechanisms of action can afford greater pain relief.
Question 3 of 5
A client is receiving dexamethasone (Decadron) therapy. What should the nurse plan to monitor in this client?
Correct Answer: B
Rationale: The drug Decadron increases gluconeogenesis. This may lead to hyperglycemia.
Therefore the blood sugar level and acetone production must be monitored.
Question 4 of 5
The client with type 2 diabetes is diagnosed with gout and prescribed allopurinol (Zyloprim). Which instruction should the nurse discuss when teaching about this medication?
Correct Answer: B
Rationale: Allopurinol increases uric acid excretion, risking kidney stones; 2–3 L water daily prevents this. Rash is possible but not probable, stomach timing is flexible, and diabetes meds are unaffected.
Question 5 of 5
The elderly client is in a long-term care facility. If the client does not have a daily bowel movement in the morning, he requests a cathartic, bisacodyl (Dulcolax). Which action is most important for the nurse to take?
Correct Answer: B
Rationale: Daily cathartics risk dependence and electrolyte imbalance; discussing complications educates and promotes safer alternatives like fiber.
