a client's holter monitor strip reveals a heart rate with normal conduction but with a rate consistently above 105 beats/minute.
Sedbober [7]

Sinus tachycardia can be the most probable condition which results into high heart rate above 105 beats/minute. This problem is not very serious and is treatable.

<h3>What is Sinus tachycardia?</h3>

Sinus tachycardia is a type of irregular heartbeat which is characterized by a faster than the normal heart rhythm. The heart's sinus node generates electrical impulses which travels through the heart muscle that causes the heart to beat. A normal sinus rhythm has an average heart rate of the range between 60 and 100 beats/minute.

Treatment is not necessary for sinus tachycardia as it is not a very serious issue. However, if an underlying condition is causing these symptoms, it needs to be treated on time. Treatments for sinus tachycardia include medications such as beta-blockers or calcium channel blockers which can lower the heart rate.

What factors may have led to Mrs. Benson’s dehydration?
masya89 [10]

Answer:

Diarrhea - the most common cause of dehydration and related deaths. The large intestine absorbs water from food matter, and diarrhea prevents this from happening. The body excretes too much water, leading to dehydration.

Vomiting - leads to a loss of fluids and makes it difficult to replace water by drinking it.

Sweating - the body's cooling mechanism releases a significant amount of water. Hot and humid weather and vigorous physical activity can further increase fluid loss from sweating. Similarly, a fever can cause an increase in sweating and may dehydrate the patient, especially if there is also diarrhea and vomiting.

Diabetes - high blood sugar levels cause increased urination and fluid loss. Tips for handling summer heat for people with diabetes.

Frequent urination - usually caused by uncontrolled diabetes, but also can be due to alcohol and medications such as diuretics, antihistamines, blood pressure medications, and anti psychotics.

Burns - blood vessels can become damaged, causing fluid to leak into the surrounding tissues.
