Question 1 of 5
Which of the following instructions regarding lithium therapy should be included in a nurse’s discharge teaching? (Select the one tha does not apply.)
Correct Answer: D
Rationale: The correct answer is D because lithium therapy requires a consistent sodium intake to maintain proper electrolyte balance. Restricting sodium content can lead to lithium toxicity. Choice A is important to avoid interactions with caffeine. Choice B is crucial to prevent fluctuations in sodium levels. Choice C is essential to prevent dehydration and maintain proper kidney function. Therefore, restricting sodium content is not a suitable instruction for lithium therapy.
Question 2 of 5
What does the nurse know to be correct concerning the use of mannitol in patients?
Correct Answer: A
Rationale: The correct answer is A: It decreases intracranial pressure. Mannitol is an osmotic diuretic that works by drawing water from brain tissue into the bloodstream, reducing intracranial pressure. This helps to manage conditions such as cerebral edema. Choices B and C are incorrect because mannitol does not impact intraocular pressure or cause sodium and potassium retention. Choice D is incorrect as mannitol causes diuresis rapidly within minutes to hours, not over several days.
Question 3 of 5
A patient taking medication for mental illness develops restlessness and an uncontrollable need to be in motion. The nurse analyzes that these symptoms relate to which drug action?
Correct Answer: B
Rationale: The correct answer is B: Dopamine-blocking effects. Restlessness and an uncontrollable need to be in motion are known side effects of medications that block dopamine receptors in the brain. Dopamine is a neurotransmitter that plays a role in movement control, and blocking its action can lead to motor side effects like restlessness. Anticholinergic effects (choice A) would cause dry mouth, blurred vision, and constipation. Endocrine-stimulating effects (choice C) would affect hormone levels, not movement. Ability to stimulate spinal nerves (choice D) would cause muscle contractions or pain, not restlessness.
Question 4 of 5
A nurse is caring for a female diagnosed with a mental disorder who has been prescribed medication. Which fact will most impact the nurse’s assessment for possible side effects?
Correct Answer: A
Rationale: The correct answer is A because women are at higher risk for tardive dyskinesia while taking conventional antipsychotic medications. This fact is crucial for the nurse's assessment because tardive dyskinesia is a serious side effect characterized by involuntary movements and can be irreversible. Understanding this risk allows the nurse to closely monitor the patient for symptoms and intervene promptly if needed. Choice B is incorrect because there is no evidence to suggest that women experience more severe side effects than men while taking atypical antidepressants. Choice C is incorrect as there is no generalization that women are more susceptible to developing a dependence on most psychiatric medications compared to men. Choice D is incorrect because there is no established evidence that women are less susceptible to developing common side effects of antipsychotic medications than men.
Question 5 of 5
A 38-year-old man has come into the urgent care center with severe hip pain after falling from a ladder at work. He says he has taken several pain pills over the past few hours but cannot remember how many he has taken. He hands the nurse an empty bottle of acetaminophen (Tylenol). The nurse is aware that the most serious toxic effect of acute acetaminophen overdose is which condition?
Correct Answer: C
Rationale: The correct answer is C: Hepatic necrosis. Acetaminophen overdose can lead to severe liver damage due to the production of a toxic metabolite. This metabolite depletes glutathione stores in the liver, leading to oxidative stress and hepatocellular injury. Hepatic necrosis can progress to acute liver failure, which can be life-threatening. Tachycardia (choice A) and central nervous system depression (choice B) are not the most serious toxic effects of acetaminjson overdose. Nephropathy (choice D) is not a common consequence of acetaminophen overdose compared to hepatic necrosis.
