WGU Pathophysiology Final Exam

Correct Answer: C

Rationale: The correct response is to remind the patient that antiretroviral drugs are most effective when taken consistently and as prescribed. Choice A is incorrect because taking a double dose after missing a dose is not recommended, as it can lead to medication toxicity. Choice B is incorrect as it may give the impression that missing doses is acceptable, which can reduce the effectiveness of the treatment. Choice D is incorrect because while consistency is important, the focus should be on treatment effectiveness rather than side effects.

Correct Answer: D

Rationale: The correct answer is D: Active artificial immunity. A tetanus booster shot confers protection through active artificial immunity. Active immunity involves the body producing its antibodies in response to an antigen, providing long-lasting protection. In this case, the tetanus booster shot triggers the student's immune system to produce specific antibodies against tetanus toxins. Choices A, B, and C are incorrect because passive immunity does not involve the individual's immune system producing antibodies; instead, it involves the direct transfer of antibodies from another source (natural or artificial) for immediate, but temporary, protection.

Correct Answer: A

Rationale: The correct answer is A. Long-term hormone replacement therapy (HRT) is associated with increased risks of cardiovascular events and breast cancer. These risks should be discussed with the patient to ensure they are aware of the potential adverse effects. Choice B is incorrect because HRT does not decrease the risk of osteoporosis; in fact, it has been linked to an increased risk of this condition. Choice C is incorrect as while HRT may have positive effects on mood and energy levels for some individuals, the focus here is on the long-term risks that need to be addressed. Choice D is incorrect as HRT is indeed associated with an increased risk of venous thromboembolism, but the primary focus of the question is on cardiovascular events and breast cancer.

Correct Answer: A

Rationale: The correct answer is A: Cough and fever. After receiving the MMR vaccine, some children may experience mild adverse effects such as a low-grade fever and a mild cough. These symptoms are normal reactions to the vaccine and indicate that the child's immune system is responding appropriately. Choices B, C, and D are incorrect because pallor and listlessness, serum sickness, nausea, and vomiting are not common adverse effects associated with the MMR vaccine in children.

Correct Answer: B

Rationale: The correct answer is B. Poor feeding and constipation are common early symptoms of infant botulism, which is caused by a neurotoxin that impairs muscle function. Option A is unrelated to the presentation of botulism. Option C does not directly relate to the symptoms of botulism. Option D is more indicative of respiratory issues rather than the constellation of symptoms seen in botulism.
