A nurse is caring for a client who is receiving positive end-expiratory pressure (PEEP) via mechanical ventilation. The nurse should monitor the client for which of the following adverse effects of PEEP?
Hypoxemia
Tension pneumothorax.
Malignant hypertension
Atelectasis
The Correct Answer is B
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.

Related Questions
Correct Answer is B
Explanation
Choice A reason
While thinning of secretions can be a positive sign, it's not always visible. A decrease in peak inspiratory pressure is a more objective indicator of improved airway patency.
Choice B reason.
Peak inspiratory pressure is the maximum pressure required to push air into the lungs. If suctioning is effective, it will remove secretions and reduce airway resistance, leading to a decrease in peak inspiratory pressure.
Choice C reason:
While a productive cough can indicate that secretions are being moved, it doesn't directly measure the effectiveness of suctioning.
Choice D reason:
Flattening of the artificial airway cuff: Flattening of the artificial airway cuff is not a relevant indicator of the effectiveness of suctioning. The cuff of an endotracheal tube is inflated to prevent air leaks around the tube and to maintain proper ventilation. It is not directly related to the effectiveness of suctioning.
Correct Answer is ["B","C","E","F"]
Explanation
A. Blood pressure: A normal blood pressure for an adolescent is 110/70 mm Hg. The question does not provide the adolescent's blood pressure, so it cannot be determined if it requires follow-up or not.
B. Capillary refill: A normal capillary refill time is less than 2 seconds. A prolonged capillary refill time indicates impaired blood flow to the extremity, which could be due to vascular injury, compartment syndrome, or shock.
C. Pedal pulse: A normal pedal pulse is +2 or +3. A weak pedal pulse (+1) indicates reduced blood flow to the extremity, which could be due to vascular injury, compartment syndrome, or shock.
D. Heart rate: A normal heart rate for an adolescent is 60 to 100 beats per minute. The question does not provide the adolescent's heart rate, so it cannot be determined if it requires follow-up or not.
E. Skin temperature: A normal skin temperature is warm and dry. A cool skin temperature indicates reduced blood flow to the extremity, which could be due to vascular injury, compartment syndrome, or shock.
F. Pain: A pain level of 10 on a scale of 0 to 10 indicates severe pain that needs to be managed with appropriate analgesics and nonpharmacological interventions.
