What are the signs of hypokalemia, and why is it important to identify potassium imbalances quickly?

The purpose of the case study assignments is to apply knowledge of the information learned in each module. Read both case studies below and think about the associated discussion questions using your best critical thinking skills. Formulate answers based on the readings and your nursing judgement. Then, create one document using AP format to discuss the questions in both case studies Please keep this in mind as you are formulating your answers.All written work submitted must conform to current APA guidelines and demonstrate college-level writing style using proper spelling, grammar and punctuation. All written work must be the original work of the student, stated in the student’s own words, except when short segments are quoted in APA format. Follow APA rules by including a cover page, running head and a reference page. You may use your book as a reference.Case Study 2aMr. E, age 53, has a history of alcoholism and went to his physician because of recent anorexia, nausea, and diarrhea, as well as heart palpitations and fatigue.

She is now complaining that her shoes are fitting too tightly, and she has developed poorly healing sores on her legs and ankles. A closer examination also shows distention in her varicose veins. Blood tests reveal a low level of proteins in the plasma.Discussion Questions for Case Study 2bBased on the patient history and the signs and symptoms, identify the fluid imbalance the patient is experiencing, and state the rationale for your answer. (See Edema.)Discuss the four general causes of edema and how they apply in the case of this patient. (See Causes of Edema.)Discuss the swelling, sores, varicose vein distention, and other effects that edema can have on a patient. (See Effects of Edema.)
