How should a healthcare professional manage a patient with suspected myocardial infarction (MI)?

Correct Answer: A

Rationale: Administering oxygen and seeking emergency help are crucial initial steps in managing a patient with suspected myocardial infarction (MI). Oxygen helps to improve oxygenation to the heart muscle, reducing its workload and preventing further damage. Calling for emergency help ensures timely access to advanced medical care, including interventions like thrombolytics. Monitoring vital signs and providing pain relief are important but secondary to the immediate need for oxygen and emergency assistance. Providing nitroglycerin and thrombolytics should be done under medical supervision and following appropriate protocols, not as the first step. Administering diuretics and altering the patient's diet are not indicated in the acute management of MI.

Correct Answer: A

Rationale: Corrected Question: To assess a patient with a tracheostomy, the healthcare professional should primarily focus on monitoring for infection and ensuring the airway remains patent. Choice A is the correct answer as these actions are crucial for tracheostomy management. Suctioning airway secretions and providing humidified oxygen (Choice B) are interventions that may be necessary based on the assessment findings but are not the initial assessment steps. Similarly, cleaning the stoma and changing tracheostomy ties (Choice C) are important aspects of tracheostomy care but do not specifically address the initial assessment. Educating the patient on tracheostomy care (Choice D) is important, but it is not the primary assessment action needed when assessing a patient with a tracheostomy.

Correct Answer: A

Rationale: The correct answer is A. Common complications of diabetes include retinopathy (damage to the retina) and nephropathy (kidney damage). These complications can be managed effectively with regular screening to detect any signs early on. Choice B is incorrect as neuropathy and cardiovascular disease are other complications of diabetes but are managed through various treatments and lifestyle modifications, not just medication. Choice C is incorrect as although foot ulcers and hypertension are associated with diabetes, the management involves proper foot care practices and blood pressure control, respectively. Choice D is incorrect as hypertension and liver disease are not the typical complications of diabetes, and insulin therapy is not the primary management for these conditions.

Correct Answer: A

Rationale: The correct answer is A: Electrolyte imbalance and dehydration. Diabetic ketoacidosis can lead to imbalances in electrolytes such as potassium, sodium, and chloride, as well as dehydration due to excess urination and vomiting. These complications should be managed promptly with appropriate fluids and insulin. Choices B, C, and D are incorrect. Hypoglycemia and increased urination are not typical complications of diabetic ketoacidosis; kidney failure and respiratory distress may occur in severe cases but are not the primary complications. Liver failure and hypertension are not directly associated with diabetic ketoacidosis.

Correct Answer: A

Rationale: The correct answer is A: Excessive thirst and fruity breath odor. Diabetic ketoacidosis presents with these early signs due to ketone buildup in the body. Choice B, weight loss and increased urination, are more characteristic of uncontrolled diabetes but not specific to diabetic ketoacidosis. Choice C, nausea and vomiting, can occur in diabetic ketoacidosis but are not as early or specific as excessive thirst and fruity breath odor. Choice D, hypoglycemia and fatigue, are not typical signs of diabetic ketoacidosis; rather, diabetic ketoacidosis usually presents with hyperglycemia.
