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.

Correct Answer is ["A","B"]
Explanation
- A: Correct. Broccoli is a vegetable that does not contain tyramine, which can interact with phenelzine and cause a hypertensive crisis.
- B: Correct. Yogurt is a dairy product that does not contain tyramine, which can interact with phenelzine and cause a hypertensive crisis.
- C: Incorrect. Pepperoni pizza contains pepperoni, cheese, and tomato sauce, which are all sources of tyramine, which can interact with phenelzine and cause a hypertensive crisis.
- D: Cream cheese is a dairy product that contains little or no tyramine and is therefore, safe in a client taking phenelzine.
- E: Incorrect. Bologna sandwich contains bologna, bread, and mayonnaise, which are all sources of tyramine, which can interact with phenelzine and cause a hypertensive crisis.
Correct Answer is C
Explanation
Choice A rationale:
Instructing the client to maintain a full bladder is not relevant to an amniocentesis procedure. A full bladder may be necessary for certain other procedures, such as a pelvic ultrasound, but not for amniocentesis.
Choice B rationale:
Administering a tocolytic 30 minutes before the procedure is not a standard practice for amniocentesis. Tocolytics are medications used to suppress uterine contractions and are not routinely administered before this procedure.
Choice C rationale:
Monitoring the fetal heart rate throughout the procedure is essential during an amniocentesis. This helps assess the well-being of the fetus and ensures that the procedure is not causing fetal distress. Any changes in fetal heart rate can indicate potential complications and may require immediate intervention.
Choice D rationale:
Placing the client in Trendelenburg position during the procedure is not recommended for amniocentesis. Trendelenburg position, where the body is supine with the legs elevated higher than the head, is not routinely used during this procedure and may cause discomfort to the client without providing significant clinical benefits.
