A nurse is assessing a client suspected of having cardiac tamponade. Which of the following findings indicates the presence of pulsus paradoxus?

A. Hallucinations: As dementia progresses, especially in conditions like Alzheimer's disease, sensory perceptions can become distorted, leading to hallucinations, where the person perceives things that are not present.

B. Paranoia: Paranoia, or irrational suspicions and mistrust, often increases as dementia progresses. The person may become increasingly fearful or suspicious of others, even caregivers or family members.

C. Lethargy: While lethargy can be a symptom of dementia, it is more commonly associated with the earlier stages of the disorder when the person may experience apathy, lack of interest, and reduced energy levels. As the disease progresses, other behavioral changes like agitation or restlessness may become more prominent.

D. Impulsivity: Impulsivity, or acting without forethought or consideration of consequences, can increase as dementia progresses, particularly in certain types of dementia like frontotemporal dementia. This can manifest as impulsive behaviors such as excessive spending, inappropriate social behavior, or risky actions.

E. Disregard for caregiver's feelings: As dementia advances, the person's ability to empathize or recognize the feelings and needs of others may decline. They may become increasingly self-focused or unaware of the impact of their actions on caregivers, leading to behaviors that disregard or overlook the caregiver's feelings and well-being.

A. Difficulty swallowing: Difficulty swallowing is not typically associated with atrial fibrillation. It may be a symptom of various other conditions such as dysphagia, esophageal disorders, or neurological disorders, but it is not a common manifestation of atrial fibrillation.

B. Shortness of breath: This is the correct answer. Shortness of breath, or dyspnea, is a common symptom of atrial fibrillation. Atrial fibrillation can lead to ineffective atrial contraction, resulting in decreased cardiac output and potential fluid accumulation in the lungs, leading to dyspnea.

C. Exertional fatigue: This is the correct answer. Exertional fatigue, or feeling excessively tired or weak with physical activity, is a common manifestation of atrial fibrillation. Reduced cardiac output and inefficient heart function due to irregular heart rhythms can lead to fatigue, especially during exertion.

D. Weight gain: Weight gain is not typically associated with atrial fibrillation. While some individuals with heart conditions may experience fluid retention and subsequent weight gain, it is not a specific manifestation of atrial fibrillation itself.
