Question 1 of 5
The following can cause hypertension EXCEPT:
Correct Answer: C
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 2 of 5
A 52-year-old woman with essential hypertension, hypercholesterolemia, and chronic-stable angina develops severe constipation. It is attributed to one of her medications. Which was the most likely cause?
Correct Answer: C
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 3 of 5
After 6 months of taking imipramine (Tofranil) for depressive symptoms, a client complains that the medication doesn’t seem as effective as before. Which question should the nurse ask to determine the cause of this problem?
Correct Answer: B
Rationale: The correct answer is B. Smoking cigarettes can affect the metabolism of imipramine, potentially leading to reduced effectiveness. The nurse should inquire about the number of packs smoked daily to assess this impact. Choice A is incorrect as tyramine-rich foods are relevant for MAOI medications, not imipramine. Choice C is not directly related to imipramine's efficacy. Choice D is incorrect as St. John's wort can interact with many medications, but not specifically imipramine.
Question 4 of 5
To educate a patient regarding what to expect following the administration of a benzodiazepine, the nurse must understand that benzodiazepines:
Correct Answer: A
Rationale: Step 1: Benzodiazepines are known for their rapid onset of action, typically within 30 minutes to 1 hour after administration. Step 2: They enhance the inhibitory neurotransmitter GABA's effects, leading to sedative, anxiolytic, and muscle relaxant properties. Step 3: Rapid onset of peak action aligns with the pharmacokinetics of benzodiazepines, making option A the correct answer. Summary: Option B is incorrect as benzodiazepines increase, not reduce, GABA availability. Option C is incorrect as benzodiazepines enhance, rather than diminish, GABA activity. Option D is incorrect as benzodiazepines primarily interact with GABA, not serotonin.
Question 5 of 5
When interviewing and planning care for a patient with fear of public speaking, the nurse must be aware that social phobias are often treatable with:
Correct Answer: B
Rationale: The correct answer is B: beta-blockers. Beta-blockers are commonly used to treat performance anxiety, including fear of public speaking, by blocking the effects of adrenaline on the body. This helps reduce physical symptoms such as rapid heartbeat and trembling, allowing the individual to feel calmer and more in control during public speaking. Neuroleptics (A), tricyclic antidepressants (C), and monoamine oxidase inhibitors (D) are not typically used to treat social phobias like fear of public speaking, as they target different neurotransmitters and symptoms. Beta-blockers are a more appropriate choice for managing the physical symptoms associated with performance anxiety.
