Correct Answer: B

Rationale: The best approach to assist a client in performing self-care after an acute myocardial infarction, especially when the client expresses concern about fatigue, is to gradually resume self-care tasks while focusing on rest periods. This approach allows the client to build confidence in managing their self-care activities while also addressing the issue of fatigue. Choice A is incorrect as it focuses on asking for assistance rather than promoting self-care. Choice C is inappropriate as it suggests delegating the client's self-care tasks to assistive personnel instead of empowering the client. Choice D is incorrect as it can lead to deconditioning and is not conducive to the client's recovery process.

Correct Answer: B

Rationale: Acetylcysteine is the antidote for acetaminophen overdose. It works by replenishing glutathione, a key component in detoxifying acetaminophen metabolites, thus preventing liver damage. Naloxone is used to reverse opioid overdose, not acetaminophen. Flumazenil is a benzodiazepine antidote. Activated charcoal is used to limit absorption in cases of poisoning, but it is not the antidote for acetaminophen overdose.

Correct Answer: B

Rationale: Encouraging the client to gradually resume self-care tasks with frequent rest periods is the best strategy to promote self-care for a client who experienced an acute myocardial infarction and is experiencing fatigue. This approach helps the client regain independence while managing fatigue. Asking family members to assist with all self-care tasks (Choice A) may hinder the client's independence. Instructing the client to remain in bed until fully rested (Choice C) may lead to deconditioning and dependency. Assigning assistive personnel to complete self-care tasks for the client (Choice D) does not empower the client to regain independence or actively participate in self-care.

Correct Answer: A

Rationale: A history of gastrointestinal bleeding is a critical finding to report to the healthcare provider because it is a contraindication for aspirin use in individuals with CAD. Aspirin can further increase the risk of bleeding in individuals with a history of gastrointestinal bleeding. Choices B, C, and D are not directly contraindications for aspirin use in this scenario. Asthma, liver disease, and hypertension are not typically contraindications for prescribing aspirin to patients with CAD.

Correct Answer: A

Rationale: The correct answer is to administer fluids. In a patient experiencing shock, the priority is to address inadequate perfusion by restoring circulating blood volume. Administering fluids helps improve perfusion and oxygen delivery to vital organs. Monitoring blood pressure, providing oxygen, and calling for assistance are important steps but administering fluids is the initial and most critical intervention in the management of shock.
