Question 1 of 5
The goal of androgen therapy in men is to
Correct Answer: D
Rationale: Androgen therapy in men, typically testosterone replacement, aims to boost libido and treat erectile dysfunction by restoring normal androgen levels, countering hypogonadism's effects like reduced sexual drive. Decreasing libido contradicts its purpose, as low testosterone already dims desire. It doesn't release follicle-stimulating hormone (FSH)-exogenous androgens may suppress FSH and LH via feedback inhibition. Increasing luteinizing hormone (LH) isn't the goal; therapy bypasses LH by directly providing testosterone. Raising libido aligns with correcting symptoms of androgen deficiency, improving quality of life and sexual function, a primary clinical indication supported by its action on androgen receptors in sexual tissues.
Question 2 of 5
A patient presents with hypotension and bradycardia. The patient indicates that one of her physicians recently prescribed three new medications to her current list of 10 medications per day. Based on this information, which statement would be the most accurate?
Correct Answer: B
Rationale: Polypharmacy-13 drugs-raises interaction risks (e.g., beta-blockers plus CCBs causing hypotension/bradycardia), a common adverse outcome in complex regimens. Allergy lacks specific signs (e.g., rash). Non-compliance isn't indicated-she reports use. Transient effects need time evidence. Polypharmacy fits symptoms, per pharmacodynamics.
Question 3 of 5
The nurse assesses the client might be experiencing toxicity from colchicine. Which statement by the client would most likely confirm the nurse's suspicion?
Correct Answer: B
Rationale: In this question, option B, "I have nausea, vomiting, and abdominal pain every day," is the most likely statement to confirm the nurse's suspicion of colchicine toxicity. Colchicine is a medication used to treat gout by reducing inflammation, but it can be toxic in higher doses. Symptoms of colchicine toxicity include gastrointestinal issues like nausea, vomiting, and abdominal pain. Option A, "My joints hurt more," is a common symptom in gout but would not specifically indicate colchicine toxicity. Option C, "I don't see as well as I used to, and my taste has changed," does not align with known symptoms of colchicine toxicity. Option D, "I wake up at night with muscle cramps," is more indicative of other conditions like electrolyte imbalances or muscle disorders rather than colchicine toxicity. Educationally, understanding the signs and symptoms of medication toxicity is crucial for nurses to provide safe and effective care. Recognizing subtle changes in a patient's condition and correlating them with potential side effects of medications is a vital skill in nursing practice to prevent adverse outcomes.
Question 4 of 5
A 24-year-old sexually active woman presents to her primary care physician with vaginal itching and a greenish, frothy vaginal discharge. Her boyfriend is asymptomatic. She is prescribed metronidazole for Trichomonas vaginalis. Which of the following should be told to avoid while taking metronidazole?
Correct Answer: A
Rationale: Metronidazole treats Trichomonas vaginalis, and alcohol must be avoided. It inhibits aldehyde dehydrogenase, causing a disulfiram-like reaction (nausea, flushing). Aspirin , caffeine , grapefruit juice , and machinery (E) lack this interaction. This precaution prevents severe discomfort, ensuring treatment adherence.
Question 5 of 5
A 31-year-old woman is planning to take a 7-day cruise to the Caribbean islands. She has never been on a ship before and fears developing motion sickness. She purchases scopolamine transdermal patch. When is the best time for her to place the patch to maximize drug efficacy?
Correct Answer: D
Rationale: In this scenario, the correct answer is D) Prior to the onset of symptoms. Placing the scopolamine transdermal patch before the onset of motion sickness symptoms is crucial for maximizing its efficacy. Scopolamine works best when it has already been absorbed into the bloodstream and is circulating in the body before the symptoms of nausea or motion sickness begin. By applying the patch in advance, the drug can reach therapeutic levels in the body, providing the individual with adequate protection against motion sickness throughout the cruise. Option A) After nausea first begins is incorrect because waiting for symptoms to occur before applying the patch means that the drug will not have enough time to take effect and prevent motion sickness effectively. Option B) After nausea occurs for 2 hours is also incorrect as delaying the application of the patch until after symptoms have already started will not provide timely relief and may lead to prolonged discomfort. Option C) After vomiting occurs is not the best choice as vomiting is a severe manifestation of motion sickness and waiting until this symptom appears is not proactive in preventing motion sickness. Educationally, it is important to teach students and healthcare professionals about the importance of timing when using medications for prophylaxis. Understanding the pharmacokinetics of drugs like scopolamine can help individuals make informed decisions regarding the timing of administration to achieve the best therapeutic outcomes. By emphasizing pre-emptive use, patients can better manage potential side effects and enjoy their travel experiences with reduced discomfort.
