Question 1 of 5
The movie Psychedelic Science highlighted the research of neuroscientist Dr Deborah Mash, who led clinical trials to test the use of the African hallucinogen ibogaine for treatment of:
Correct Answer: A
Rationale: The correct answer is A: cocaine dependence. Ibogaine has been studied for its potential to treat addiction, particularly cocaine dependence, due to its effects on the brain's reward system. Dr. Deborah Mash's research focused on this specific application. B: Paranoid schizophrenia is incorrect as ibogaine is not typically used to treat psychotic disorders like schizophrenia. C: Anxiety disorders is incorrect as ibogaine's primary focus is on addiction treatment rather than anxiety. D: Alcohol dependence is incorrect as ibogaine's research has primarily centered on cocaine addiction rather than alcohol dependence.
Question 2 of 5
A client with chronic schizophrenia has had a stroke involving the hippocampus. The client will be discharged on low doses of haloperidol. The nurse who must provide medication teaching will need to adjust the teaching plan to account for client problems with:
Correct Answer: A
Rationale: The correct answer is A: Memory. The hippocampus is crucial for memory formation and retrieval. Since the client's hippocampus is affected by the stroke, they may experience memory deficits. Teaching about medication administration needs to be adjusted to accommodate the client's impaired memory to ensure they understand and remember the instructions. Summary: - Choice A is correct because the hippocampus is involved in memory. - Choice B (Expressive aphasia) is incorrect as it pertains to language expression, not memory. - Choice C (Emotional control) is incorrect as it is not directly related to hippocampal function. - Choice D (Poor balance and coordination) is incorrect as it is not typically associated with hippocampal damage.
Question 3 of 5
A 10-year-old patient will be started on methylphenidate hydrochloride (Ritalin) therapy. The nurse will perform which essential baseline assessment before this drug is started?
Correct Answer: B
Rationale: The correct answer is B: Height and weight. Before starting methylphenidate therapy in a 10-year-old patient, it is essential to assess height and weight as this medication can affect growth and appetite. Monitoring these parameters at baseline helps establish a reference point for future assessment of treatment effects on growth. Eye examination (A) is important for long-term monitoring but not essential before starting therapy. Liver studies (C) are not typically required before starting methylphenidate therapy. Hearing test (D) is not directly related to starting this medication.
Question 4 of 5
A patient has a digoxin level of 1.4 ng/mL. The nurse interprets that this level is
Correct Answer: B
Rationale: The correct answer is B because a digoxin level of 1.4 ng/mL falls within the therapeutic range of 0.5-2 ng/mL. This level is appropriate for treating heart conditions effectively without causing toxicity. Choice A is incorrect because 1.4 ng/mL is within the therapeutic range. Choice C is incorrect as the level is not above the therapeutic range. Choice D is incorrect because a level of 1.4 ng/mL is not considered toxic.
Question 5 of 5
A patient is started on a diuretic for antihypertensive therapy. The nurse expects that a drug in which class is likely to be used initially?
Correct Answer: C
Rationale: The correct answer is C: Thiazide diuretics. Thiazide diuretics are commonly used as first-line therapy for hypertension due to their effectiveness in reducing blood pressure by promoting diuresis. They work by inhibiting sodium reabsorption in the distal convoluted tubule, leading to decreased fluid volume and lower blood pressure. Thiazides are well-tolerated and have shown to reduce cardiovascular events in hypertensive patients. Loop diuretics (A) are more potent and are typically reserved for patients with more severe fluid overload conditions. Osmotic diuretics (B) are used for acute renal failure or cerebral edema, not for hypertension. Potassium-sparing diuretics (D) are typically used in combination with thiazides to prevent hypokalemia, not as initial therapy.
