A nurse is assessing a patient suspected of having hyperthyroidism. Which of the following symptoms would support this diagnosis? (Select all that apply.)

End-stage heart failure is progressive myocardial pump failure causing systemic hypoperfusion, pulmonary congestion, hypoxia, dyspnea, palliative care, DNR directives prioritizing symptom relief, comfort-focused management, and avoidance of life-prolonging interventions therapies.

Rationale:

A. In a patient with comfort measures only and active DNR status, priority is symptom relief rather than resuscitation. The nurse should assess dyspnea severity and provide prescribed oxygen and morphine. This aligns with palliative goals and MRSA precautions protocol adherence.

B. Calling a Code Blue violates DNR orders and advance directive specifying comfort-only care. CPR initiation is inappropriate in end-stage disease. This action disregards end-of-life wishes and exposes patient to unwanted aggressive resuscitation contrary to ethical palliative care principles standards violated.

C. Documenting condition alone is incomplete during acute respiratory distress. Hypoxia requires immediate symptom management in comfort care settings. Failure to intervene with oxygen or opioids neglects palliative intervention priorities and does not address respiratory distress urgency per comfort protocol guidelines.

D. Contacting healthcare provider for ICU transfer conflicts with advance directive specifying comfort-only care. Escalation to intensive care contradicts palliative goals and DNR status. Focus should remain on symptom relief rather than invasive life-prolonging interventions in terminal heart failure clinical priority.

Cataracts involve progressive opacification of the crystalline lens, often stemming from oxidative stress and protein aggregation. This degenerative process causes light scattering, leading to painless visual impairment, decreased contrast sensitivity, and myopic shifts in refractive error.

Rationale:

A. Cataracts are characterized by a gradual, progressive decline in visual acuity rather than an acute event. Sudden vision loss is more indicative of retinal detachment or vascular occlusions. This condition typically manifests over months or years as protein denaturation increases.

B. This ocular pathology is primarily an age-related condition resulting from cumulative environmental exposure and metabolic changes. While congenital forms exist, the vast majority of cases occur in the geriatric population due to lenticular fiber compaction and hardening.

C. Chronic, unprotected exposure to ultraviolet radiation induces photochemical damage and free radical production within the lens. These stressors accelerate the cross-linking of crystallin proteins, making UV protection a critical preventative measure for ocular health and longevity.

D. The primary pathophysiology involves the loss of lens transparency, which appears as a visible milky opacity upon examination. This physical change disrupts the path of light to the retina, resulting in the classic symptom of blurred vision and glare.
