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 C

Explanation

An ileostomy is a surgical opening in the abdomen that connects the end of the small intestine (ileum) to a pouch or bag on the outside of the body. The ileostomy bypasses the large intestine (colon) and rectum, which normally absorb water and form solid stools. Therefore, the client should expect their stools to be loose and watery. The client should empty their bag several times a day, not when it is full, to prevent leakage and skin irritation. The client should avoid laxatives, which can cause dehydration and electrolyte imbalance. The client should also avoid high-fiber foods, which can cause blockage or irritation of the ileostomy.

A. Urticaria B. Mouth sores C. Headaches D. Lymphedema

Correct Answer is D

Explanation

Lymphedema is a contraindication to acupuncture because it increases the risk of infection and worsens the swelling. Acupuncture should not be performed on an oedematous limb at risk of lymphoedema.

The other options are not contraindications to acupuncture.
