- Mrs. Aguilar is a 78-year-old Caucasian woman who lives alone in a small, one-story home she and her husband purchased several years ago before he died. She lives on Social Security income and her deceased husband's corporate pension and is financially secure. Though she is in relatively good health, she has been having increasing difficulty walking for the past several years, which has been attributed to peripheral vascular disease. She complains of weakness and pain in her legs and a loss of feeling in her fingers and feet. She also suffers from occasional constipation.

After Mr. McClelland’s last bout with pneumonia and congestive heart failure, his wife of 59 years has decided she is no longer able to care for him alone. Mrs. McClelland states, “He has just gotten too weak and can’t help me care for him. I am so afraid he will fall and hurt himself. I am so worn out trying to care for him myself. I have to bathe him and remind him to eat; sometimes, I’ve had to feed him myself, or he won’t eat. He can be so forgetful.” Given this information, there are two options that Mrs. McClelland is considering. Hire an in-home nurse to care for her husband. Place her husband in a nursing home. Write 200–250 words arguing for the option you think will be best. Use the discussion prompts to guide the content for your initial post.

Habituationarrow_forwardYou are a nursing student who is assigned to a busy medical-surgical unit that specializes in the care of patients with various cardiac related disorders. One of your patients for the day is Mr. Stein, a 66 year old male with a primary diagnosis of a myocardial infarction. You enter the room to conduct your morning assessment and you find that Mr. Stein does not appear to be in a positive mood. As you begin your assessment, Mr. Stein criticizes your technique and berates you for anything you seem to do. Should you continue with your assessment? If so, could you say or do anything different to help improve the situation? How do you think receiving criticism and negative feedback may affect your job performance, if at all? Prior to beginning your assessment, could you have said or done anything that may have prevented or reduced Mr. Stein's hostility towards you?arrow_forwardYou are assigned to care for an 80-year-old man admitted to the hospital yesterday with acute coronary syndrome who had an emergent percutaneous coronary intervention with a stent placement. When you walk into his room, he states, “That last nurse gave me a medication I don’t think I was supposed to have. She told me it was metoprolol, but it looked different from the metoprolol I got yesterday.” You note that the patient’s heart rate is now 56 beats per minute (bpm), although the previous day it had been between 72 and 88 bpm. According to the patient’s chart, he received the prescribed dose of metoprolol 4 hours ago. The prescribed dosage of this medication was not changed; it was the same yesterday. What actions should be taken? Should this information be communicated to your supervisor? What is the care priority for the patient? What evidence supports or does not support disclosure of medication administration errors to patients? What steps would you take and in what orderarrow_forward

- After arriving at the ER, Leo was put on an iv and was administered nitroglycerin to cause coronary blood vessel dilation. Blood also was drawn for a series of tests including creatine kinase (CK or CK-MB) and troponins (sometimes referred to as cTnT & cTnI) levels. Results from these tests would later confirm an MI. Leo then was wheeled to the cardiac catherization lab where coronary angiography was performed with the following results: Circumflex artery - 20% blocked Right coronary artery - 15% blocked Left anterior descending artery (or anterior interventricular artery) - 80 % blocked Given the results of the angiogram, what part of his heart's muscle most likely was involved in the myocardial infarction? Explain your reasoning.arrow_forwardWhy is it so difficult to get to the heart during open heart surgery?arrow_forwardJosie was feeling tired and was unable to keep up with her normal chores.
