Activity 1 Which rat had the fastest baseline metabolic rate? Normal Rat Why did the metabolic rates differ? The hypophysectomized rat lacked thyroid-stimulating hormone. The thyroidectomized rat lacked thyroxine hormone. Activity 2 What was the effect of thyroxine on the normal rat’s metabolic rate? How does it compare to the normal rat’s baseline metabolic rate? Thyroxine caused the metabolic rate to increase; it was faster. Why was this effect seen? Because it stimulates heart rate‚

assessment finding of a. persistent skin tenting b. rapid‚ deep respirations. c. bounding peripheral pulses. d. hot‚ flushed face and neck. ANS: B Patients with metabolic acidosis caused by AKI may have Kussmaul respirations as the lungs try to regulate carbon dioxide. Bounding pulses and vasodilation are not associated with metabolic acidosis. Because the patient is likely to have fluid retention‚ poor skin turgor would not be a finding in AKI.

How Hormones Effect the Endocrine System Introduction: The endocrine system primarily relies on the negative feedback mechanism. The endocrine system influences metabolic activities by sending out chemical messengers through the blood called hormones. Once released into the blood these hormones are transported throughout the body. The effects of these hormones are wide spread and vary from reproduction‚ growth and development‚ immunities‚ maintaining electrolyte levels‚ water and nutrient balance

hypoxia is sustained hyperventilation triggered by chemoreceptors in the carotid and aortic bodies. With this prolonged hyperventilation a high alveolar P02 is produced‚ but with that there is a lowered alveolar PCO2 that results in respiratory alkalosis. This wants to decrease the ventilation‚ but renal compensation is activated‚ secreting bicarbonate and reabsorbing hydrogen which gradually brings the blood PH back to normal and allows further increase in ventilation. This acute hypoxic ventilatory

Henry Williams is a 74-year-old African American who was admitted for shortness of breath secondary to chronic obstructive pulmonary disease exacerbation. His past medical history is chronic obstructive pulmonary disease (COPD)‚ cardiovascular disease‚ hyperlipidemia‚ asthma‚ hear loss‚ and hypertension. His neighbor brought him to the emergency room because he was having difficulty breathing and weakness. When he was brought to the emergency room‚ he was very weak and restlessness.

Marieb‚ E (2000 p‚ 326) also states that this is because when large amounts of fats are being used for energy instead of sugars‚ the blood becomes very acidic (Acidosis)‚ as ketones appear in the blood. The onset of type 1 diabetes mellitus may also be associated with sudden weight loss or nausea‚ vomiting or abdominal pains‚ if Diabetic Ketoacidosis (DKA) is present. Although DKA is not a presenting symptom of

Patients with diabetes need to understand what diabetes is. Patients who understand what diabetes is and the complicated process associated with the disease are more likely to comply with the prescribed regimen. Diabetes Mellitus is a syndrome with disordered metabolism and inappropriate hyperglycemia due to either a deficiency of insulin secretion or to a combination of insulin resistance and inadequate insulin secretion to compensate (Davis‚ 2001). Diabetes is a chronic progressive disease that

around in different ways that ultimately change the shape of the enzyme. After the enzyme’s active site has changed shape‚ the substrate will not longer fit‚ causing the enzyme not work properly. “If the pH climbs to an unacceptably high value called alkalosis then enzymes cease to function effectively‚” (Sang‚ 2013). To avoid changes in pH‚ buffers are used. Buffers are a substance found in the blood that prevent changes in pH levels‚ which helps enzymes to function
