Extract:
Question 1 of 5
Which finding in the patient's history contraindicates the use of Imitrex (sumatriptan) for the prevention of migraine headaches?
Correct Answer: B
Rationale: Sumatriptan (Imitrex) is a vasoconstrictor contraindicated in patients with angina due to the risk of coronary artery vasoconstriction and ischemia. Diabetes renal calculi and peptic ulcer disease are not contraindications for sumatriptan.
Question 2 of 5
A client with COPD is in respiratory failure. Which of the following results would be the most sensitive indicator that the client requires a mechanical ventilator?
Correct Answer: C
Rationale: A pH of 7.23 indicates severe respiratory acidosis, suggesting inadequate ventilation and the need for mechanical ventilation. PCO2 58 (
A) and HCO3 30 (
D) are elevated but less critical, and SaO2 90 (
B) is low but not definitive.
Question 3 of 5
A client with cirrhosis of the liver becomes comatose and is started on neomycin 300 mg q6h via nasogastric tube. The rationale for this therapy is to:
Correct Answer: C
Rationale: Neomycin is an antibiotic, but this is not the rationale for administering it to a client in hepatic coma. Diuretics and salt-free albumin are used to promote diuresis in clients with cirrhosis of the liver. Neomycin destroys the bacteria in the intestines. It is the bacteria in the bowel that break down protein into ammonia. Lactulose is administered to create an acid environment in the bowel. Ammonia leaves the blood and migrates to this acidic environment where it is trapped and excreted.
