Pathophysiology Final Exam

Correct Answer: C

Rationale: The correct answer is C: 'The patient should be observed for anaphylaxis for 30 minutes after administration.' This is because anaphylaxis can occur within minutes of administration of an immunization. By observing the patient for 30 minutes, the nurse can promptly identify and manage any signs of anaphylaxis. Choices A, B, and D are incorrect as they suggest shorter or longer observation periods, which may not be sufficient to detect and respond to anaphylaxis in a timely manner.

Correct Answer: B

Rationale: The correct answer is to assess for signs of bleeding or hematoma. After a thoracentesis, it is crucial to monitor for any bleeding or hematoma formation at the puncture site, as this can lead to complications. Monitoring for signs of infection (Choice A) is essential but is usually a delayed concern compared to the immediate risk of bleeding post-procedure. While monitoring vital signs and respiratory status (Choice C) is important, assessing for bleeding takes precedence to address any immediate complications. Instructing the client to rest and limit physical activity (Choice D) is relevant for general post-procedure care but is not the most critical intervention in this scenario.

Correct Answer: A

Rationale: The correct answer is to apply the testosterone gel to the chest or upper arms. This is important to minimize the risk of transfer to others. Applying the gel to the lower abdomen, thighs, face, or neck can increase the risk of transfer to others, especially women and children who should avoid contact with testosterone gel. Applying it to the scalp and back is not recommended as these areas are not suitable for absorption of the medication.

Correct Answer: D

Rationale: When serotonin levels increase, more neurotransmitters will cross the synaptic cleft and bind with postsynaptic receptors, facilitating enhanced communication. Option A is incorrect because chemical synapses, unlike electrical synapses, are unidirectional. Option B is incorrect because neurotransmitters impact communication with multiple neurons, not just a single connected neuron. Option C is incorrect because neurotransmitters cross the synaptic cleft, not gap junctions.

Correct Answer: A

Rationale: The correct instruction the nurse should provide regarding the use of medroxyprogesterone acetate (Provera) for endometriosis is to take the medication at the same time each day. This helps to maintain consistent hormone levels and ensures the effectiveness of the treatment. Choice B is incorrect because medroxyprogesterone should be taken without regard to meals. Choice C is incorrect because side effects should be reported to the healthcare provider for evaluation rather than discontinuing the medication without medical advice. Choice D is incorrect as medroxyprogesterone is usually taken daily, not weekly, for the treatment of endometriosis.
