A nurse is assessing a client who has hypoxemic respiratory failure. Which of the following findings should the nurse expect?

Pulmonary edema

Opioid toxicity

Myasthenia gravis

Flail chest

Answer and Explanation

The Correct Answer is A

A. Pulmonary edema: Pulmonary edema occurs when fluid accumulates in the lungs, impairing gas exchange and leading to hypoxemia. This condition is a common cause of hypoxemic respiratory failure, and patients often present with symptoms such as dyspnea, crackles on auscultation, and hypoxemia. The nurse would expect this finding in a client experiencing hypoxemic respiratory failure.
B. Opioid toxicity: Opioid toxicity can cause respiratory depression, but it typically leads to hypoventilation, which results in hypercapnic respiratory failure (elevated carbon dioxide levels) rather than hypoxemic respiratory failure. Therefore, while opioid toxicity affects breathing, it is not directly associated with hypoxemic respiratory failure.
C. Myasthenia gravis: Myasthenia gravis is a neuromuscular disorder that leads to muscle weakness, including respiratory muscles. While it can cause respiratory failure in severe cases, it does not directly cause hypoxemic respiratory failure. Respiratory failure in myasthenia gravis is often due to insufficient ventilation rather than impaired oxygenation, so this is not the expected finding in hypoxemic respiratory failure.
D. Flail chest: Flail chest occurs due to multiple rib fractures that result in a segment of the chest wall moving paradoxically, impairing ventilation. While this condition can lead to respiratory failure, it typically causes hypercapnic rather than hypoxemic respiratory failure. Therefore, it is less likely to be the cause of hypoxemic respiratory failure in this scenario.

Correct Answer is D

Explanation

A. Client's age: Age is a non-modifiable risk factor for stroke. As individuals get older, their risk of stroke increases due to vascular changes, but this is not something that can be altered or controlled through interventions or lifestyle changes.
B. History of sickle cell disease: Sickle cell disease increases stroke risk due to its effects on blood viscosity and vessel occlusion, but it is a genetic condition. Therefore, it is considered a non-modifiable risk factor, although managing the disease can help reduce complications.
C. Parent who has cardiovascular disease: Having a parent with cardiovascular disease increases one’s risk for stroke due to inherited genetic predisposition. However, this familial risk is not something the client can change, making it a non-modifiable factor.
D. Hypertension: Hypertension is the most significant modifiable risk factor for stroke. It can be managed through lifestyle changes, medication, and monitoring, thereby significantly reducing the client’s risk of future strokes.

A. Proximal acinar emphysema B. Centrilobular emphysema C. Panacinar emphysema D. Distal acinar emphysema

Correct Answer is D

Explanation

A. Proximal acinar emphysema: This subtype typically affects the central or proximal parts of the acini, and it is less commonly associated with pneumothorax. The condition primarily affects the respiratory bronchioles.
B. Centrilobular emphysema: Centrilobular emphysema involves the upper lobes and is commonly associated with smoking, but it does not directly lead to pneumothorax as often as distal acinar emphysema.
C. Panacinar emphysema: Panacinar emphysema affects the entire acinus, including the alveoli. Although it can cause significant respiratory issues, it is less strongly associated with pneumothorax compared to distal acinar emphysema.
D. Distal acinar emphysema: Distal acinar emphysema involves the distal parts of the acinus and is often seen in the upper lobes of the lungs. It is strongly associated with the development of pneumothorax, as the damage to the lung tissue can lead to spontaneous ruptures in the alveolar walls, causing air to leak into the pleural space.
