The nurse is assessing a client newly diagnosed with hyperthyroidism. The nurse should expect which of the following?
Low serum thyroxine (T4) level
Decreased serum thyroid stimulating hormone (TSH)
Tachycardia or fine hand tremor
Elevated serum thyroid stimulating hormone (TSH)
Elevated serum thyroxine (T4)
The Correct Answer is C
A. Low serum thyroxine (T4) level In hyperthyroidism, the serum thyroxine (T4) level is typically elevated due to excessive production of thyroid hormones.
B. Decreased serum thyroid stimulating hormone (TSH) In hyperthyroidism, the body produces excess thyroid hormones (T3 and T4), which negatively feedback to the pituitary gland and result in decreased TSH levels. This is a key diagnostic finding.
C. Tachycardia or fine hand tremor Hyperthyroidism often causes symptoms like tachycardia (increased heart rate) and a fine hand tremor due to the overstimulation of the body's metabolism and sympathetic nervous system.
D. Elevated serum thyroid stimulating hormone (TSH) In hyperthyroidism, the TSH level is typically low due to negative feedback from the excess thyroid hormones.
E. Elevated serum thyroxine (T4) In hyperthyroidism, the serum thyroxine (T4) level is elevated because the thyroid gland is producing too much thyroid hormone.

Correct Answer is A
Explanation
A. The priority for treating delirium is to identify and address the underlying cause. Delirium is often a symptom of an acute condition such as infection, metabolic disturbances, medication side effects, or other physical issues. Treating the root cause of delirium can help resolve the condition more effectively.
B. While creating a calm, quiet environment can help reduce confusion and agitation, it is not the most critical aspect of treatment. The main focus should be on addressing the cause of the delirium.
C. Reorienting the client is important for safety and reducing confusion, but it will not be sufficient to resolve the delirium if the underlying cause is not addressed. Reorientation is a supportive measure, not the priority intervention.
D. Although monitoring nutrition is important for overall health, it is not the first priority in treating delirium unless malnutrition is identified as a contributing factor to the delirium.
Correct Answer is C
Explanation
A. Donepezil (Aricept) does not stop or cure Alzheimer's disease. It helps to manage symptoms, but it does not halt the progression of the disease. The disease will still progress, but the medication may help improve cognitive function and slow down symptom deterioration temporarily.
B. Donepezil may take several weeks to months to show any noticeable effects. Immediate improvements in cognitive function are unlikely, and it should not be expected to cause quick or dramatic changes in thinking.
C. Donepezil is a cholinesterase inhibitor that works by increasing acetylcholine levels in the brain, which helps to improve communication between nerve cells. It helps manage the cognitive symptoms of Alzheimer's disease, such as memory loss and confusion, but does not cure or prevent the disease.
D. Donepezil works by inhibiting acetylcholinesterase, the enzyme that breaks down acetylcholine. By doing this, it helps increase the availability of acetylcholine in the brain, rather than slowing its uptake. This increased availability can help improve cognitive function in people with Alzheimer's disease.
