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
Explanation
Choice A rationale:
Storing personal items together on a shelf in the bathroom promotes organization and reduces the risk of tripping or falling over scattered items. Keeping the environment tidy and free of clutter is an essential fall prevention strategy, especially in areas where the client moves frequently.
Choice Brationale:
Wearing a yellow wristband to indicate a fall risk is a common practice in healthcare facilities. However, merely wearing the wristband does not demonstrate a comprehensive understanding of fall prevention strategies. While it is essential for healthcare providers to identify patients at risk of falling, educating the patient about specific strategies to prevent falls is equally important.
Choice C rationale:
Keeping the overhead lights on at all times does not necessarily indicate an understanding of fall prevention strategies. While adequate lighting is important to prevent falls, leaving lights on continuously may not be necessary during daylight hours. It is more effective to ensure there is adequate lighting in commonly used areas and during nighttime hours.
Choice Drationale:
Wearing a restraint around the waist is not a recommended fall prevention strategy. Physical restraints are generally discouraged in healthcare settings due to ethical concerns and the potential to cause harm to the patient. Restraints can lead to complications such as pressure ulcers, loss of muscle strength, and decreased mobility.
Correct Answer is B
Explanation

- A is incorrect because tinnitus, or ringing in the ears, is not an adverse effect of captopril, but rather a symptom of other conditions such as ear infection, noise exposure, or medication toxicity.
- B is correct because cough is a serious adverse effect of captopril, which is an angiotensinconverting enzyme (ACE) inhibitor that can cause angioedema, or swelling of the airways.
- C is incorrect because polyuria, or excessive urination, is not an adverse effect of captopril, but rather a symptom of other conditions such as diabetes mellitus, diabetes insipidus, or diuretic use.
- D is incorrect because blurred vision is not an adverse effect of captopril, but rather a symptom of other conditions such as eye strain, refractive error, or cataract.
