The nurse recognizes that which of the following phenomena has contributed to his tissue damage? a. Decreased blood viscosity has resulted in interstitial bleeding. b. Reactive vasodilation has compromised perfusion. c. Autonomic nervous stimulation has resulted in injury. d. Decreased blood flow has induced hypoxia.

10. The nurse is taking the client's blood pressure. The physician asks for the pulse pressure. To obtain the pulse pressure, the nurse will have to do which of the following things? A. Obtain a pulse-pressure machine. B. Subtract the diastolic blood pressure from the systolic. C. Subtract the systolic blood pressure from the diastolic. D. Take client's apical pulse and subtract it from systolic.

2. Describe how blood and cell metabolism can be affected and how that can be used limit acute inflammation. 3. Explain in a paragraph why ice should not be applied prior to exercise. What specific things can be negatively affected? 4. Why should ice be used for 10-20 minutes every few hours? 5-9. Give 5 specific instances that can be treated with cryotherapy.

1. A previously healthy 25-year-old-woman comes to the emergency department because of a 3-day history of fever, chest pain, and rapidly progressive shortness of breath. Use of an over-the-counter cold medication has not relieved her symptoms. She has no history of serious illness and takes no other medications. Her temperature is 40oC (104o F), pulse is 128/min and regular, respirations are 28/min and blood pressure is 80/54 mm Hg. Physical examination shows jugular venous distention and weak pulses in all extremities. Auscultation of the chest shows diffuse crackles bilaterally, muffled heart sounds, and a soft S2 gallop. After 30 minutes she goes into ventricular fibrillation and cannot be resuscitated. At autopsy, the heart is diffusely pale and floppy with focal petechiae, all chambers are markedly dilated.Histologic examination of cardiac tissue shows a lymphocytic infiltrate and myocardial necrosis. Which of the following infectious agents is the most likely cause these…

4. The heart, kidney, brain, retina and arterial blood vessels are prime targets of hypertensive damage. Uncontrolled and untreated AH accelerates the damage to these organs and could cause their failure.5. Medicines used to treat high blood pressure include: Water pills (diuretics), Angiotensin-converting enzyme (ACE) inhibitors, Angiotensin II receptor blockers (ARBs), Calcium channel blockers, Alpha-beta blockers,and etc6. Aldosterone (ALD) is a hormone your adrenal glands release that helps regulate blood pressure by managing the levels of sodium and potassium in your blood.

Which of thefollowing laboratory abnormalities is most likely in this patient?a. Decreased serum calcitonin concentrationb. Decreased serum glucose concentrationC. Increased serum thyroxine (T4) concentrationd. Increased urine hydroxyindoleacetic acid concentratione. Increase urine metanephrine concentration
