A nurse is preparing a sterile field to perform a sterile dressing change. Which of the following interventions should the nurse use to maintain surgical aseptic technique?

Hold hands folded below the waist after donning sterile gloves

Pick up and pour solutions with the palm of the hand covering bottle labels

Keep sterile items within a 1.3 cm (0.5 in) border of the sterile drape

Maintain sterile objects within the line of vision

Answer and Explanation

The Correct Answer is D

Maintain sterile objects within the line of vision.

A. Hold hands folded below the waist after donning sterile gloves. This is incorrect because holding hands below the waist can contaminate the gloves with microorganisms from the floor or clothing.
B. Pick up and pour solutions with the palm of the hand covering bottle labels. This is incorrect because covering bottle labels can obscure important information such as expiration dates or ingredients.
C. Keep sterile items within a 1.3 cm (0.5 in) border of the sterile drape. This is incorrect because the border of the sterile drape is considered contaminated and any sterile item that touches it becomes contaminated as well.
D. Maintain sterile objects within the line of vision. This is correct because keeping an eye on sterile objects ensures that they are not accidentally touched by nonsterile items or persons.

Correct Answer is B

Explanation

A. Hypoxemia is a condition of low oxygen levels in the blood. PEEP can actually improve oxygenation by preventing alveolar collapse and increasing functional residual capacity.

B. Tension pneumothorax is a life-threatening condition of air accumulation in the pleural space that causes increased intrathoracic pressure and compresses the lungs, heart, and great vessels. PEEP can increase the risk of tension pneumothorax by creating excessive positive pressure in the airways and alveoli.

C. Malignant hypertension is a severe form of high blood pressure that can cause organ damage and stroke. PEEP can cause a transient increase in blood pressure due to increased intrathoracic pressure, but it does not cause malignant hypertension.

D. Atelectasis is a condition of partial or complete lung collapse due to alveolar collapse or obstruction. PEEP can prevent or treat atelectasis by maintaining positive pressure in the airways and alveoli.

A. Attach a prefilled syringe to the catheter inflation hub. B. Position the sterile drape leaving the perineum exposed. C. Cleanse the client's meatus with antiseptic solution. D. Lubricate the catheter with water-soluble gel.

Correct Answer is C

Explanation

Choice A rationale:

Attaching a prefilled syringe to the catheter inflation hub is a step performed after the catheter insertion to inflate the balloon, securing the catheter in the bladder. This action is not the first step and should not be done before cleansing the meatus and positioning the sterile drape.

Choice B rationale:

Positioning the sterile drape leaving the perineum exposed is a necessary step in maintaining the sterility of the procedure area. However, it is not the first action the nurse should take. Cleaning the client's meatus with an antiseptic solution is the initial step to prevent infection during catheter insertion.

Choice C rationale:

Cleaning the client's meatus with antiseptic solution is the first step in inserting an indwelling urinary catheter. This action helps to reduce the risk of urinary tract infection by minimizing the introduction of bacteria into the urethra.

Choice D rationale:

Lubricating the catheter with water-soluble gel is a step performed after cleansing the meatus and positioning the sterile drape. It facilitates the smooth insertion of the catheter into the urethra. However, it is not the first action to be taken.
