A nurse is checking a client's ventilator settings. The nurse should understand that positive end- expiratory pressure has which of the following purposes?

To deliver a set tidal volume

To provide positive airway pressure during inspiration

To control the rate of ventilations

To prevent alveolar collapse

Answer and Explanation

The Correct Answer is D

Positive end-expiratory pressure (PEEP) is a mode of mechanical ventilation that maintains a positive pressure in the airways at the end of expiration, preventing alveolar collapse and improving oxygenation. PEEP does not affect tidal volume, inspiratory pressure, or ventilation rate, which are determined by other ventilator settings.

Correct Answer is A

Explanation

The client who has an allergy to bananas may also have an allergy to latex, as they share some common proteins that can trigger an immune response. The nurse should avoid using latex gloves, catheters, syringes, or other products that may contain latex when caring for this client. The other options are not related to banana allergy.

A. "I should use canned instead of frozen vegetables." B. "I can season my foods with lemon juice." C. "I should use salt sparingly while cooking." D. "I can use baking soda when I bake."

Correct Answer is B

Explanation

A 2-g sodium diet means limiting sodium intake to no more than 2000 mg per day. Sodium is found in salt and many processed foods, such as canned vegetables, soups, sauces, and baked goods. Sodium can cause fluid retention and worsen heart failure symptoms, such as shortness of breath, swelling, and fatigue. Therefore, the client should avoid adding salt or salt substitutes (such as baking soda) to their foods and choose fresh or frozen vegetables over canned ones. Lemon juice is a low-sodium alternative that can add flavor to foods without increasing sodium intake.
