Which of the following could the nurse expect to observe in an older adult client who has a pneumothorax?
Higher oxygen saturations of 98% to 99%
Lower oxygen saturations of 93% to 94%
Lower energy expenditure
Increased lung capacity
The Correct Answer is B
Choice A Reason:
Higher oxygen saturations of 98% to 99% is inappropriate. A pneumothorax involves the presence of air in the pleural space, which can compromise lung function and gas exchange. This compromised lung function typically leads to decreased oxygenation of the blood, resulting in lower oxygen saturations rather than higher saturations.
Choice B Reason:
Lower oxygen saturations of 93% to 94% is appropriate. A pneumothorax disrupts the normal exchange of oxygen and carbon dioxide in the lungs due to partial or complete lung collapse. As a result, the affected lung is unable to adequately oxygenate the blood, leading to lower oxygen saturations, which are indicative of hypoxemia.
Choice C Reason:
Lower energy expenditure is inappropriate. Energy expenditure is not typically affected by a pneumothorax. While the discomfort and respiratory distress associated with a pneumothorax may cause the individual to limit physical activity, there is no direct impact on overall energy expenditure.
Choice D Reason:
Increased lung capacity is inappropriate. A pneumothorax results in partial or complete collapse of the affected lung, reducing lung capacity rather than increasing it. The presence of air in the pleural space creates positive pressure, which can compress the lung and decrease its ability to expand fully during inhalation.

Correct Answer is B
Explanation
Choice A Reason:
Drooling is inappropriate. Drooling, also known as sialorrhea, is a common symptom in Parkinson's disease due to impaired swallowing and reduced control of the muscles involved in saliva production. Anticholinergic medications can exacerbate dry mouth, which may contribute to drooling. However, drooling is not typically a side effect that would be specifically associated with anticholinergic use.
Choice B Reason:
Anhidrosis is appropriate. Anhidrosis refers to the inability to sweat normally. Anticholinergic medications can inhibit sweating by blocking the action of acetylcholine on sweat glands, leading to decreased sweating and potentially causing hyperthermia. Anhidrosis is a potential side effect of anticholinergic agents and should be reported to the healthcare provider due to the risk of overheating.
Choice C Reason:
Tremors is inappropriate. Tremors are a common symptom of Parkinson's disease and are typically not caused by anticholinergic medications. In fact, anticholinergic agents are often prescribed to help reduce tremors in individuals with Parkinson's disease. Tremors would not be considered an adverse effect that the client should report in the context of anticholinergic therapy.
Choice D Reason:
Rigidity is inappropriate. Rigidity, or stiffness of the muscles, is a characteristic symptom of Parkinson's disease resulting from the loss of dopamine-producing neurons in the brain. While anticholinergic medications can help alleviate some symptoms of Parkinson's disease, they are not typically associated with rigidity. Rigidity would not be considered an adverse effect that the client should report in the context of anticholinergic therapy.
Correct Answer is D
Explanation
"The nerves just go to sleep when I lie down because no message gets from my brain to the spinal cord." is incorrect because it does not accurately describe the mechanism of peripheral neuropathy. Peripheral neuropathy in diabetes is not simply the nerves "going to sleep" due to lack of communication between the brain and spinal cord.
Choice B Reason:
"The nerve damage may occur for unknown reasons in any individual" is incorrect because while the exact cause of peripheral neuropathy may not always be known, in the context of diabetes mellitus, the link between elevated blood sugar levels and nerve damage is well-established.
Choice C Reason:
"The older I get, there is less blood flowing to my feet. “is incorrect because while decreased blood flow (ischemia) can contribute to peripheral neuropathy in some cases, the primary mechanism in diabetic neuropathy is nerve damage due to hyperglycemia rather than reduced blood flow.
Choice D Reason:
"The elevated blood sugar from my diabetes can cause underlying nerve damage." Peripheral neuropathy is a common complication of diabetes mellitus, particularly when the condition is uncontrolled. Elevated blood sugar levels over time can lead to damage to the nerves, especially those in the feet and legs. This damage can result in symptoms such as numbness, tingling, burning sensations, or pain in the affected areas.
