Question 1 of 5
The nurse is performing a health history on a patient who is ordered to begin therapy with valproic
Correct Answer: D
Rationale: Valproic acid is known to have potential hepatotoxicity, meaning it can damage the liver. Therefore, if a patient already has liver disease, it can increase the risk of further liver damage when taking valproic acid. The nurse needs to be particularly cautious when a patient with pre-existing liver disease is prescribed this medication, as close monitoring of liver function tests will be necessary to detect any signs of liver damage early on. It is important to assess and consider the patient's liver condition before initiating valproic acid therapy to prevent potential adverse effects.
Question 2 of 5
Selegiline:
Correct Answer: A
Rationale: Selegiline selectively inhibits MAO-B, increasing dopaminergic activity in Parkinson's disease treatment.
Question 3 of 5
A 40-year-old patient experiencing periods of mania and periods of depression would most likely benefit from which of the following?
Correct Answer: D
Rationale: Carbamazepine, a mood stabilizer, treats bipolar mania/depression-per psychiatry-unlike atomoxetine (ADHD), amitriptyline (depression), or methylphenidate (ADHD). It fits cycles, per evidence.
Question 4 of 5
The nurse is aware that the following solutions are routinely used to flush an IV device before and after the administration of blood to a patient is:
Correct Answer: A
Rationale: 0.9 percent sodium chloride, also known as normal saline, is routinely used to flush an IV device before and after the administration of blood to a patient. Normal saline is isotonic, meaning it has a similar concentration of salt and water as the body's cells. This makes it compatible for use in various medical procedures, including flushing IV devices to ensure patency and prevent clotting. Other solutions like 5 percent dextrose in water, sterile water, and heparin sodium are not typically used for flushing IV devices before and after blood administration.
Question 5 of 5
The nurse teaching a pre-conception class would tell participants that they should be most careful about exposure to drugs during which stage of pregnancy?
Correct Answer: D
Rationale: The embryonic stage (weeks 3-8) is peak risk-organogenesis makes fetuses vulnerable to teratogens (e.g., alcohol causing FAS), per developmental biology. Equal risk ignores stages. Pre-implantation (pre-week 3) has less organ impact. Third trimester affects growth, less malformation. Embryonic caution is critical, shaping warnings.
