Questions: A nurse is preparing to measure a client's vital signs. The nurse should identify that which of the following factors will affect the methods that are used? (Select all that apply.) The client who has a BMI of 35 . The client has had nausea for 2 days. The client is reporting a "stuffy" nose. The client has been fasting for blood tests. The client is taking digoxin for an irregular heart rate. The client had a mastectomy 2 years ago.

The answer includes the following factors:

1. The client who has a BMI of 35.
2. The client is reporting a "stuffy" nose.
3. The client is taking digoxin for an irregular heart rate.
4. The client had a mastectomy 2 years ago.

Explanation:

1. The client who has a BMI of 35: A high BMI can affect the accuracy of certain measurements, such as blood pressure. The nurse may need to use a larger cuff to ensure an accurate reading.

2. The client has had nausea for 2 days: This factor is less likely to affect the methods used for measuring vital signs directly. Nausea might influence the client's comfort and cooperation but does not typically necessitate a change in measurement methods.

3. The client is reporting a "stuffy" nose: A stuffy nose can affect the method used to measure respiratory rate and oxygen saturation. The nurse might need to use alternative methods if the client is unable to breathe comfortably through their nose.

4. The client has been fasting for blood tests: Fasting can affect blood glucose levels but does not typically change the methods used for measuring vital signs like blood pressure, heart rate, or temperature.

5. The client is taking digoxin for an irregular heart rate: Digoxin affects heart rate and rhythm, which can influence how the nurse monitors the client's pulse and heart rate. The nurse may need to take additional care in measuring and interpreting these vital signs.

6. The client had a mastectomy 2 years ago: A mastectomy can affect the method used to measure blood pressure. The nurse should avoid using the arm on the side of the mastectomy to prevent lymphedema and other complications.

Summary: The factors that will affect the methods used to measure the client's vital signs include a high BMI, a stuffy nose, taking digoxin for an irregular heart rate, and having had a mastectomy. These factors necessitate adjustments in the standard procedures to ensure accurate and safe measurements.
