Which of the following selections lists conditions that would lead to increased stroke volume?
a) increased preload, increased afterload, increased contractility
b) decreased preload, decreased afterload, decreased contractility
c) increased preload, decreased afterload, increased contractility
d) decreased preload, increased afterload, increased contractility
e) increased preload, increased afterload, decreased contractility
Greater stroke volume would result from increased preload, decreased afterload, and increased contractility. So, option C is correct.
Medical emergencies include strokes. Stroke symptoms include difficulty speaking, understanding, and walking as well as paralysis or numbness in the face, arm, or leg.
Preload is the collective term for the elements that cause passive muscular tension in the muscles when they are at rest. At the conclusion of diastole, preload, which is proportional to end-diastolic volume, is the passive ventricular wall stress. In general, an increase in preload results in a rise in stroke volume.
Afterload takes longer for the heart to build up enough pressure to force open the aortic valve. As a result, less energy is expended ejecting the stroke volume and more energy is expended building up the pressure. This results in a reduction in the stroke volume.
The term "contractility" refers to the inotropy, or force, of myocyte contraction. The volume of the stroke grows as the heart's contraction force rises because it can force more blood out of the chambers.

What are the factors that affect how much heat is absorbed by a body?
Heat energy is affected by mass, specific heat, and variations in body temperature.
Exothermic chemical reactions occur in numerous organs of the human body. Heat is produced as a byproduct of those chemical interactions, which the blood absorbs and redistributes around the organs. This spreads the heat evenly and guarantees that the entire body is at the same temperature.
The hypothalamus, a component of the brain, regulates internal body temperature. The hypothalamus compares the present temperature to the typical temperature of around 37°C. If the body's temperature falls too low, the hypothalamus ensures that heat is generated and maintained. Hypothermia is a medical emergency caused by the body losing heat faster than it can create heat, resulting in a dangerously low body temperature.

Functionally, there are no valves in arteries (as opposed to in veins) because there is no blood flow in reverse because the blood pressure in the arteries is so high.
Blood pressure is the force that flowing blood exerts against the walls of blood vessels (BP). The heart's work of pumping blood through the circulatory system is primarily responsible for this pressure. The pressure in the major arteries is meant when the word "blood pressure" is used without qualifier. The ratio of diastolic pressure, or the lowest pressure experienced between two heartbeats, to systolic pressure, or the highest pressure experienced during one heartbeat, is frequently used to calculate blood pressure.

Mr. L is a 58-year-old man who is recovering in the orthopedic unit of the hospital from a right total knee replacement of two days ago. Mr. L has type 1 diabetes and was diagnosed with the condition at 12 years of age. He has been managing his illness with blood glucose checks 4 times a day: before meals and once at bedtime. He currently takes Humulin-R on a sliding scale based on his glucose results. He weighs 315 lbs. and has developed osteoarthritis in both knees, requiring surgical replacement of the knee joint on the right side.
The nurse caring for Mr.L. enters his room at 8:15 AM for a morning assessment. She finds Mr. L lying in his bed awake, but his mental status is altered and there is a fruity odor to his breath. His vital signs are: HR 100bpm, RR 32/minute, BP 116/78 mm Hg. The nurse notes that his last blood glucose level was 156 mg/dl the previous night before bed and he received 2 units of insulin at that time, but he has not received his morning glucose check or any insulin yet today. A rapid bedside glucose check reveals a blood glucose level of 468 mg/dl. The nurse contacts the physician and upon further examination, Mr. L is diagnosed with diabetic ketoacidosis.
Describe how diabetic ketoacidosis could develop in a patient who has undergone surgery.
Mr. L has an elevated respiratory rate that is classified as Kussmaul respirations. Explain this type of respiratory pattern.
Mr. L complains of feeling very thirsty and that he can’t see very well because his vision is suddenly blurry. The nurse notes he has a large amount of clear urine in his catheter bag. She takes a sample of urine and it tests positive for ketone bodies.
How does the body release ketone bodies into the urine when DKA occurs.
Explain why Mr. L would have increased urinary output, blurred vision, and increased thirst.
The physician has given orders to administer 0.9% Sodium Chloride IV at 500 mL/hour for 1 hour, then 200mL/hour for the next 4 hours. The nurse is to start a drip of Regular insulin at 0>1mg/kg/hour. The physician has also added orders for lab work, including a metabolic profile and arterial blood gases. The metabolic panel results are: Na 135 mEq/L, K 3.2mEq/l, CL 95mmol/L, Ca 8.5mg/dl. The arterial blood gases results are as follows: ph 7.31, pCO2 20 mmHg, pO2 95 mmHg, HCO3 12 mmol/L
What is the rationale for the IV fluids to be given at this rate?
Explain why the patient’s potassium result is at the current level?
Based on the metabolic profile results, what is the next step that the nurse would most likely need to perform?
Explain why DKA would most likely produce these types of blood gas results.
An hour after the insulin was started, the nurse checks Mr. L.’s blood glucose levels and notes it has decreased to 208 mg/dl. He appears more comfortable and his vital signs are: HR 92 bpm, RR 22/ minute, BP 116/70mm Hg, O2 saturation 95% on 2L of oxygen.
What should the nurse do next?
The nurse should advice the patient to get admitted in the hospital one or two days prior to any operation so that he may be put under surveillance before the surgery.
For such patients, it is advised to wait a few days before their scheduled surgery. When possible, even urgent surgery should be postponed to give patients with diabetic crises time to stabilize. The physiologic stressor known as surgery can cause ketoacidosis. Insulin resistance increases as a result of the postoperative upregulation of regulatory hormones such glucagon, growth hormone, and cortisol.
Increased postoperative morbidity and mortality as well as an increased need for surgical operations are all related to diabetes. Perioperative ketoacidosis or hyperosmolar syndrome can arise from the stress response to surgery and the ensuing hyperglycemia, osmotic diuresis, and hypoinsulinemia.

Heat causes temperature changes, size changes, and condition changes, and might even result in chemical changes.
Heat accumulation within human body could be induced by a mix of environmental and internal heat created by metabolic activities. Rapid heat gain caused by exposure to hotter-than-average circumstances affects the body's ability to control temperature and therefore can result in a chain reaction of disorders such as increasing prevalence of chronic, heat exhaustion, heatstroke, or hyperthermia.
Heat-related deaths and hospitalizations can occur extremely quickly (the same day) or have a delayed effect (many days later), resulting in accelerated mortality or sickness in the already feeble, as seen in the opening days of heatwaves.
