WGU Pathophysiology Final Exam

Correct Answer: C

Rationale: In a patient receiving isoniazid (INH) and rifampin (Rifadin) with symptoms of decreased urinary output and decreased sensation in great toes, assessing urine culture and sensitivity is crucial. These symptoms could indicate peripheral neuropathy, a known side effect of isoniazid, and rifampin can cause renal toxicity. Checking for any urinary tract infection or drug-induced nephrotoxicity is important. Choices A, B, and D are incorrect as they do not directly address the symptoms presented by the patient or the potential side effects of the medications mentioned.

Correct Answer: B

Rationale: In Guillain-Barr� syndrome, respiratory muscle weakness can lead to respiratory compromise, making it crucial to prioritize monitoring for signs of respiratory distress. Monitoring oxygen saturation levels is important but is secondary to assessing for respiratory compromise in this condition. Changes in consciousness and monitoring blood pressure closely are not typically the priority in Guillain-Barr� syndrome.

Correct Answer: B

Rationale: The correct answer is B. Tinidazole (Tindamax) is known to cause a bitter or metallic taste in the mouth. This side effect is common and indicates that the patient understands the medication they are taking. Choices A, C, and D are incorrect because they do not specifically relate to the common side effects or administration details of tinidazole.

Correct Answer: B

Rationale: The correct answer is B: 'Do not take more than one dose in a 24-hour period.' It is essential for the nurse to emphasize this instruction to prevent potential adverse effects from taking multiple doses of sildenafil. Choice A is incorrect because sildenafil should be taken approximately 30 minutes to 4 hours before sexual activity, not specifically 1 hour before. Choice C is important but not the priority; while vision or hearing loss are potential serious side effects of sildenafil, the immediate concern should be focused on dose frequency. Choice D is incorrect as sildenafil can be taken with or without food.

Correct Answer: C

Rationale: Individuals with type O blood have both anti-A and anti-B antibodies in their body. This is because type O blood lacks A or B antigens on the surface of red blood cells, causing the body to produce antibodies against both A and B antigens. Therefore, the correct answer is C. Choice A and B only antibodies are incorrect because type O individuals have both anti-A and anti-B antibodies. Choice D is incorrect as O represents the blood type itself, not the antibodies present in the blood.
