A male patient is receiving testosterone therapy for hypogonadism. What adverse effect should the nurse monitor for during this therapy?

Correct Answer: A

Rationale: The correct answer is A: Increased risk of cardiovascular events. Testosterone therapy for hypogonadism is associated with an increased risk of cardiovascular events, such as myocardial infarction and stroke. Monitoring for signs and symptoms of cardiovascular issues is crucial during testosterone therapy. Choices B, C, and D are incorrect because testosterone therapy is not typically associated with an increased risk of liver dysfunction, prostate cancer, or bone fractures.

Correct Answer: C

Rationale: The correct answer is C. Oral contraceptives can be less effective when taken with certain antibiotics as they may interfere with the effectiveness of the contraceptive. It is important for patients to be aware of this interaction to consider additional contraceptive methods during antibiotic therapy. Choices A and B are incorrect as no contraceptive method is 100% effective, and oral contraceptives typically require a period of time to reach full effectiveness. Choice D is incorrect as taking oral contraceptives with food does not significantly impact their effectiveness.

Correct Answer: B

Rationale: The correct answer is B: Metronidazole (Flagyl). When treating extraintestinal amebiasis, chloroquine is often used in combination with metronidazole to ensure the eradication of the parasite. Metronidazole helps to target the infection more effectively. Choices A, C, and D are incorrect. Iodoquinol (Yodoxin) is another antiprotozoal agent but is not typically used in combination with chloroquine for amebiasis. Metyrosine (Demser) is used in the management of pheochromocytoma, and carbamazepine (Tegretol) is an anticonvulsant and mood-stabilizing drug, neither of which are indicated for extraintestinal amebiasis.

Correct Answer: A

Rationale: The correct answer is A: Increased risk of liver dysfunction. Testosterone therapy can lead to liver dysfunction, including cholestatic jaundice and hepatitis. This adverse effect necessitates monitoring of liver function tests during testosterone therapy. Choice B, increased risk of prostate cancer, is incorrect because testosterone therapy does not cause prostate cancer but is contraindicated in patients with known or suspected prostate cancer. Choice C, increased risk of bone fractures, is incorrect as testosterone therapy is actually associated with an increase in bone mineral density, reducing the risk of fractures. Choice D, increased risk of breast cancer, is incorrect because testosterone therapy in males does not increase the risk of breast cancer.

Correct Answer: A

Rationale: The correct answer is A. Tamoxifen increases the risk of venous thromboembolism. Patients should be educated about signs and symptoms of blood clots, such as swelling, pain, or redness in the legs. Choices B, C, and D are incorrect because tamoxifen is not associated with decreasing the risk of osteoporosis, causing hot flashes and menopausal symptoms, or causing weight gain and fluid retention.

Correct Answer: B

Rationale: The correct answer is B: 'vigilant adherence to the drug regimen.' When initiating oral contraceptive therapy, the success of preventing pregnancy relies heavily on the patient's commitment to following the prescribed regimen consistently. Compliance with taking the oral contraceptives as directed is crucial for their effectiveness. Choice A, 'current health status,' is not the primary factor for successful prevention of pregnancy with oral contraceptives. Choice C, 'knowledge of sexual health,' while important, is not the primary determinant of contraceptive efficacy. Choice D, 'risk factors for adverse effects,' though relevant for monitoring and managing side effects, is not the primary focus for ensuring contraceptive success.

Correct Answer: C

Rationale: The correct answer is C. Hormonal contraceptives increase blood levels of clotting factors, particularly factors II, VII, IX, and X. This elevation in clotting factors can predispose individuals to thromboembolic events, including blood clots. Choices A, B, and D are incorrect because hormonal contraceptives do not have a significant effect on serum triglycerides and cholesterol, platelet levels, or causing direct injury to blood vessel linings as the primary mechanism for clot formation.

Correct Answer: D

Rationale: When administering an immunization, it is essential to have epinephrine available in case of an allergic reaction such as anaphylaxis. Epinephrine is the medication of choice for treating severe allergic reactions due to its ability to reverse the symptoms rapidly. Diphenhydramine and hydroxyzine are antihistamines that can help manage mild allergic reactions but are not the primary medications for severe reactions like anaphylaxis. Physostigmine is not indicated for managing allergic reactions and is used for specific conditions such as anticholinergic toxicity.

Correct Answer: A

Rationale: Lung cancer is the leading cause of cancer-related deaths in both men and women globally. It is strongly associated with smoking and exposure to environmental toxins. Breast cancer (choice B) primarily affects women, while colorectal cancer (choice C) and prostate cancer (choice D) are more gender-specific. Colorectal cancer is more common in both men and women but not the leading cause of cancer-related deaths.
