Question 1 of 5
A 39-year-old man with long-standing allergies has no health insurance and simply takes over-the-counter diphenhydramine for symptom relief. He has no other medical problems but uses this medication up to four times per day. Which of the following effects of this medication is possible to be experienced by this patient?
Correct Answer: B
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 2 of 5
Which of the following agents may cause tremors as a side effect and, thus, should be used with caution in patients with Parkinson's disease, even though it is also indicated for the treatment of dementia associated with Parkinson's disease?
Correct Answer: C
Rationale: Rivastigmine, an acetylcholinesterase inhibitor, treats Parkinson's disease dementia by enhancing cholinergic function, improving cognition. However, increased acetylcholine can exacerbate tremors, a core Parkinson's symptom, by disrupting dopamine-acetylcholine balance in the basal ganglia, requiring cautious use. Benztropine, an anticholinergic, reduces tremors, not causes them. Rotigotine, a dopamine agonist, improves motor symptoms. Dimethyl fumarate manages MS, not Parkinson's dementia, and lacks tremor association. Rivastigmine's benefit in dementia must be weighed against its potential to worsen tremors, making it the drug needing careful monitoring in this context.
Question 3 of 5
A client calls the clinic and tells the nurse that she has missed taking several of her contraceptive pills during the current cycle. What is the best instruction for the nurse to give the client?
Correct Answer: D
Rationale: Missing oral contraceptive pills reduces their efficacy, increasing pregnancy risk. If several pills are missed , the hormonal protection is compromised, requiring an alternative method (e.g., condoms) for the cycle's remainder to prevent conception. Immediate pregnancy testing assesses outcome, not prevention. Suggesting a new method addresses future planning, not current risk. Choice C underestimates the risk, as even fewer than three missed pills can disrupt efficacy, depending on timing. The nurse's best instruction (D) ensures immediate protection, aligning with contraceptive guidelines for missed doses, prioritizing safety and efficacy.
Question 4 of 5
The client receives estrogen for prostate cancer. He asks the nurse why he is receiving a female hormone. What is the best response by the nurse?
Correct Answer: C
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 5 of 5
A client is prescribed spironolactone (Aldactone) for hypertension. Which electrolyte should the nurse monitor closely?
Correct Answer: B
Rationale: Spironolactone, a potassium-sparing diuretic, treats hypertension by blocking aldosterone, reducing sodium reabsorption while retaining potassium . This risks hyperkalemia (>5.0 mEq/L), causing arrhythmias or muscle weakness, especially in renal impairment. Monitoring potassium closely ensures early detection, critical for safety. Sodium may drop mildly but isn't the primary concern. Calcium and magnesium aren't directly affected. Potassium's elevation aligns with spironolactone's mechanism, distinct from other diuretics that deplete it, making it the priority electrolyte. Regular checks (e.g., serum levels) prevent toxicity, particularly in hypertension where cardiac stability is key, thus B is the nurse's focus for vigilant monitoring and timely intervention.
