A nurse is preparing a sterile field for a client who requires a dressing change. Which of the following actions should the nurse plan to take?

Drop the sterile gauze from 25.4 cm (10 in) above the sterile field.

Hold the sterile package in his dominant hand and open the top flap of the package toward his body.

Place objects 1.27 cm (0.5 in) inside the border of the sterile field.

Position the bottle outside the edge of the sterile field when pouring solution into a sterile container.

Answer and Explanation

The Correct Answer is A

Rationale:

A. Drop the sterile gauze from 25.4 cm (10 in) above the sterile field: Dropping sterile items from a height of about 6 to 12 inches prevents contamination by keeping hands outside the sterile field and ensuring the item lands safely without touching nonsterile surfaces.

B. Hold the sterile package in his dominant hand and open the top flap of the package toward his body: The top flap should be opened away from the nurse’s body to maintain sterility and prevent the arm from crossing over the sterile field, which would risk contamination.

C. Place objects 1.27 cm (0.5 in) inside the border of the sterile field: The outer 2.5 cm (1 inch) of the sterile field is considered contaminated. Placing items only 0.5 inches inside this border would place them within the contaminated zone, risking sterile field compromise.

D. Position the bottle outside the edge of the sterile field when pouring solution into a sterile container: While the bottle should not touch the sterile field, it must be close enough to pour without splashing, and the sterile container must be inside the sterile field.

Correct Answer is B

Explanation

Rationale:

A. Canned black beans: While black beans are a healthy source of protein and fiber, canned varieties are often high in sodium unless labeled low-sodium. High sodium intake can worsen hypertension, so these should be limited or thoroughly rinsed before use.

B. Fish: Fish, particularly those high in omega-3 fatty acids like salmon and mackerel, can help lower blood pressure and reduce cardiovascular risk. They are a heart-healthy protein source recommended in hypertension management.

C. Red meat: Red meat is often high in saturated fat and cholesterol, which can contribute to elevated blood pressure and heart disease. It should be limited in a diet designed to control hypertension.

D. Cheese: Many cheeses are high in sodium and saturated fat, which can increase blood pressure and cardiovascular strain. Even small portions may contain significant sodium, making them less ideal for clients with hypertension.

A. Establish a patent oral airway. B. Remove the client's clothing. C. Warm blood products prior to administration. D. Assign the client a score on the Glasgow Coma Scale

Correct Answer is A

Explanation

Rationale:

A. Establish a patent oral airway: The airway is the highest priority in trauma care, following the ABCs (Airway, Breathing, Circulation). Without a patent airway, the client cannot oxygenate properly, which can quickly become life-threatening.

B. Remove the client's clothing: This helps with full-body assessment and prevention of missed injuries, but it should only be done after ensuring the client’s airway and breathing are stable.

C. Warm blood products prior to administration: While this helps prevent hypothermia during transfusion, warming blood is not the immediate priority in a trauma situation. Circulation support follows airway and breathing in priority.

D. Assign the client a score on the Glasgow Coma Scale: Neurological assessment is important but comes after airway stabilization. The GCS helps evaluate consciousness but should not delay securing the airway in an emergency.
