A nurse assesses a 60kg adult client who is 5 feet 5 inches tall. What is the estimated body mass index (BMI) for this client? Round to the whole number.

(a) Inquire about family history of headaches:

While understanding the client's family history of headaches can be important for a comprehensive assessment, it is not the immediate priority. The description of "the worst headache" ever experienced could indicate a serious condition that needs urgent attention.

(b) Review the client's medical record:

Reviewing the client's medical record provides valuable information about their history and potential underlying conditions. However, given the severity of the reported headache, it is crucial to perform a more immediate physical assessment to rule out life-threatening conditions.

(c) Assess the client's blood pressure:

Assessing the client's blood pressure is a critical initial action. A severe headache can be a symptom of hypertensive crisis, stroke, or other serious conditions. High blood pressure could provide an immediate clue to the severity and cause of the headache, allowing for quicker intervention.

(d) Provide medication for pain relief:

Providing pain relief is important, but it should not be the first action without determining the cause of the headache. Administering medication without assessing the client's condition could mask symptoms of a potentially serious underlying issue such as a stroke or hypertensive emergency.

(a) Soles of the feet:

The soles of the feet are not considered the most reliable indicator of central cyanosis because peripheral areas can be affected by various factors, including temperature and circulation. Changes in color here might not accurately reflect central oxygenation status.

(b) Oral mucosa:

The oral mucosa is the most reliable indicator of central cyanosis because it reflects the oxygenation status of the central circulatory system. Cyanosis in this area indicates a significant drop in arterial oxygen saturation and is a more direct indicator of hypoxemia compared to peripheral sites.

(c) Ear lobes:

Ear lobes, like the soles of the feet, can be influenced by peripheral circulation and environmental factors. While cyanosis can be observed here, it is not as reliable as central sites like the oral mucosa for assessing systemic oxygenation.

(d) Conjunctivae:

The conjunctivae can show signs of cyanosis, but the oral mucosa is still a more sensitive and reliable indicator for central cyanosis. The oral mucosa provides a clear and consistent site to assess oxygenation in emergency situations.
