What are the signs of an acute myocardial infarction?

Correct Answer: A

Rationale: The correct answer is A: Chest pain radiating to the arm and shortness of breath. These are classic signs of an acute myocardial infarction. Choice B is incorrect because nausea, vomiting, and high fever are not typical signs of a heart attack. Choice C is incorrect as headache, confusion, and low blood pressure are not specific to myocardial infarction. Choice D is incorrect because an acute myocardial infarction typically presents with an increased heart rate, not bradycardia.

Correct Answer: A

Rationale: The correct answer is A. A neurological assessment includes evaluating the level of consciousness and motor function as they are key components in assessing neurological function. Choices B, C, and D are incorrect as headache, nausea, reflexes, pupil size, tremors, and confusion may be part of a neurological assessment but are not the key components that are fundamental for a comprehensive assessment.

Correct Answer: A

Rationale: The correct answer is A: Administer bronchodilators and monitor oxygen levels. Asthma management involves using bronchodilators to help open the airways and improve breathing. Monitoring oxygen levels is essential to ensure the patient is getting enough oxygen. Choice B, encouraging deep breathing exercises, can be helpful for some respiratory conditions but is not a key intervention for managing an acute asthma attack. Choice C, providing corticosteroids and monitoring for respiratory distress, is important for long-term asthma management and severe exacerbations but is not the immediate key intervention during an acute attack. Choice D, providing antihistamines and monitoring blood pressure, is not typically indicated for asthma management as asthma is primarily an airway disease, not a histamine-mediated condition.

Correct Answer: A

Rationale: The client with low blood glucose needs immediate assessment to ensure that the orange juice has corrected the hypoglycemia. Monitoring the effectiveness of the intervention for low blood glucose is the priority. The other options, such as a client scheduled for a procedure in 1 hour, a client with fluid remaining in the IV bag, and a client who received pain medication 30 minutes ago, do not require immediate assessment like the client with low blood glucose.

Correct Answer: C

Rationale: Ataxia and incoordination are signs of phenytoin toxicity rather than adverse reactions to rifampin or isoniazid. These symptoms indicate that the client is experiencing an adverse effect of phenytoin, requiring a dose adjustment. Choice A is incorrect because rifampin is not typically associated with ataxia and incoordination. Choice B is incorrect as the development of ataxia and incoordination does not necessarily mean the seizure disorder is no longer under control. Choice D is incorrect as the symptoms are more indicative of phenytoin toxicity rather than adverse effects of combination antimicrobial therapy.
