Question 1 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.

Question 3 of 5

Correct Answer: A

Question 4 of 5
When a client is receiving vasoactive therapy IV, such as dopamine (Intropin), and extravasation occurs, the nurse should be prepared to administer which of the following medications directly into the site?
Correct Answer: A
Rationale: Phentolamine is given to counteract the-adrenergic effects that cause ischemia and necrosis of local tissue. Epinephrine is an endogenous catecholamine that produces vasoconstriction and increases heart rate and contractility. Phenylephrine causes constriction of arterioles of skin, mucous membranes, and viscera, which in turn can cause ischemia and necrosis. Sodium bicarbonate is an alkalinizing agent that is incompatible with dopamine.
Question 5 of 5
The client is admitted with a diagnosis of postpartum depression. Which medication is most likely to be ordered?
Correct Answer: B
Rationale: Postpartum depression is treated with antidepressants (e.g. SSRIs) to address mood symptoms. Antibiotics magnesium sulfate and tocolytics are used for other conditions not depression.
