Multiple Choice

In the context of homeostasis, which assessment finding by the nurse would warrant immediate action?

A patient with a heart rate of 72 beats per minute

A patient with a body temperature of 98.6°F

Verified step by step guidance

Understand the concept of homeostasis: Homeostasis refers to the body's ability to maintain a stable internal environment despite changes in external conditions. It involves the regulation of various physiological parameters such as temperature, blood pressure, and glucose levels.

Identify normal ranges for physiological parameters: A normal heart rate is typically between 60-100 beats per minute, a normal body temperature is around 98.6°F, normal blood pressure is approximately 120/80 mmHg, and normal blood glucose levels are between 70-100 mg/dL when fasting.

Evaluate each assessment finding: Compare each patient's vital sign to the normal ranges. A heart rate of 72 beats per minute and a body temperature of 98.6°F are within normal limits. A blood glucose level of 70 mg/dL is also within the normal fasting range.

Assess the blood pressure reading: A blood pressure of 180/120 mmHg is significantly higher than the normal range and indicates hypertension, which can be a medical emergency requiring immediate attention.

Determine the priority for action: Based on the comparison with normal ranges, the blood pressure reading of 180/120 mmHg is the most concerning finding and warrants immediate action to prevent potential complications such as stroke or heart attack.
