The nurse is caring for hospitalized clients. Which nursing action requires the nurse to use sterile gloves?

A. Vitamin D is often referred to as the "sunshine vitamin" because the body produces it in response to sunlight exposure on the skin. Spending more time indoors reduces sunlight exposure, which can lead to insufficient production of vitamin D in the body. Vitamin D is important for bone health, immune function, and other physiological processes.

B. Vitamin E deficiency is rare in healthy individuals with a balanced diet. It is primarily found in foods such as nuts, seeds, and vegetable oils. Deficiency can occur in conditions where fat absorption is impaired or in certain genetic disorders.

C. There are several B vitamins (e.g., B1, B2, B6, B12) that are essential for various metabolic processes in the body. Deficiencies in specific B vitamins can occur due to inadequate dietary intake, malabsorption

disorders, or other medical conditions. However, preference for indoor activities does not directly correlate with increased risk of vitamin B deficiency.

D. Vitamin A deficiency is more commonly associated with inadequate intake of foods rich in vitamin A (e.g., liver, carrots, sweet potatoes) rather than sunlight exposure. Vitamin A is important for vision, immune function, and cellular growth.

D. When uncertain about the endpoint of Korotkoff sounds, releasing the cuff completely allows the blood flow to return to normal in the arm. After waiting for about two minutes, the nurse can reinflate the cuff and begin the measurement process again. This approach helps ensure accurate measurement by resetting conditions and allowing for a clearer determination of when Korotkoff sounds start and stop.

A. This option is not recommended because re-inflating the cuff immediately could lead to incorrect readings due to inaccurate pressure settings or discomfort for the client. It does not address the issue of determining the endpoint of the Korotkoff sounds.

B. This technique involves palpating the radial pulse while inflating the cuff and then inflating the cuff until the pulse is no longer palpable. This method can help ensure the cuff is inflated to an appropriate pressure level, which is typically about 30 mmHg above the point where the radial pulse disappears.

However, this option does not directly address the uncertainty about when to listen for the Korotkoff sounds to stop.

C. This option is not practical for addressing the immediate uncertainty during the current blood pressure measurement. Waiting 30 minutes to retake the blood pressure with a different cuff may delay necessary assessment and intervention.
