ATI Capstone Medical Surgical Assessment 2 Quizlet

Correct Answer: A

Rationale: The priority action when the nurse administers insulin for a misread blood glucose reading is to monitor for signs of hypoglycemia. Insulin administration based on a misread blood glucose could lead to hypoglycemia due to an unnecessary dose. Monitoring for signs of hypoglycemia is crucial for prompt intervention if blood glucose levels drop dangerously low. Option B, monitoring for hyperglycemia, is incorrect in this situation as the concern is over-treatment with insulin causing hypoglycemia. Option C, administering glucose IV, is only necessary if hypoglycemia occurs. Option D, documenting the incident, is important for reporting and learning purposes but is not the immediate priority when the focus is on patient safety and preventing complications.

Correct Answer: A

Rationale: The correct answer is A: 'Avoid items like mint that increase gastric acid secretion.' Mint can relax the lower esophageal sphincter, leading to increased gastric acid secretion and worsening GERD symptoms. Choice B is a good recommendation for GERD management as it helps prevent excessive stomach distension. Choice C is also a recommended practice to avoid reflux during sleep. Choice D, avoiding black and red pepper, is not directly linked to exacerbating GERD symptoms, so it is not the most relevant recommendation for a patient diagnosed with GERD.

Correct Answer: A

Rationale: The correct answer is to monitor for hypoglycemia. Administering insulin based on a misread glucose level can lead to hypoglycemia. Monitoring for hypoglycemia is crucial as it is a potential adverse effect of the insulin administration. Administering glucose IV (Choice B) is not the priority as there is no indication of hypoglycemia yet. Documenting the incident (Choice C) is important but not the immediate priority over patient safety. Monitoring for hyperglycemia (Choice D) is not the priority after administering insulin in response to a misread glucose level.

Correct Answer: A

Rationale: Flattened T waves are the classic ECG finding in hypokalemia. Hypokalemia primarily affects the repolarization phase of the cardiac action potential, leading to T wave abnormalities. While prominent U waves are typically associated with hypokalemia as well, flattened T waves are the most specific and sensitive ECG abnormality seen in hypokalemia. Elevated ST segments and wide QRS complexes are not typically seen in hypokalemia and are more indicative of other electrolyte imbalances or cardiac conditions.

Correct Answer: A

Rationale: Flattened T waves are the most common ECG change seen in patients with hypokalemia. Hypokalemia leads to a decrease in serum potassium levels, affecting the repolarization phase of the cardiac action potential. This results in T wave flattening or inversion. ST elevation is typically seen in conditions like myocardial infarction, not in hypokalemia. Wide QRS complex is more associated with hyperkalemia than hypokalemia. Tall T waves are often seen in hyperkalemia, not hypokalemia.
