Knowledge Check:
Note: It’s ok to use the Citation (McCance, 2019) for all of them due to the material coming primarily from the Patho/Mosby’s textbook.
You have five essays in Knowledge Check (KC) to gauge your understanding of this module’s content. Due by the end of week 3. Please provide at least one primary citation and its supporting reference for each question. Most commonly, students support their answers with classroom textbook readings.

Question 1
Scenario 1: Myocardial Infarction
CC: “I woke up this morning at 6 a.m. with numbness in my left arm and pain in my chest. It feels tight right here (mid-sternal).” “My dad had a heart attack when he was 56 years old and I am scared because I am 56 years old.”
HPI: The patient is a 56-year-old Caucasian male who presents to the Express Hospital Emergency Department with a chief complaint of chest pain that radiates down his left arm. He states this started this morning and has been worsening, pointing to the mid-sternal area, “it feels like an elephant is sitting on my chest and having a hard time breathing”. He rates the pain as 9/10. Nothing has made the pain better or worse. He denies any previous episodes of chest pain. Denies nausea, or lightheadedness—Nitroglycerin 0.4 mg tablet sublingual x 1 which decreased pain to 7/10.
Lipid panel reveals Total Cholesterol 424 mg/dl, high-density lipoprotein (HDL) 26 mg/dl, Low-Density Lipoprotein (LDL) 166 mg/dl, Triglycerides 702 mg/dl, Very Low-Density Lipoprotein (VLDL) 64 mg/dl
His diagnosis is an acute inferior wall myocardial infarction.
Question #1:
Which cholesterol is considered the “good” cholesterol and what does it do?
Question 2

Question #2:

Question 3
Scenario 2: Pleural Friction Rub
A 35-year-old female with a positive history of systemic lupus erythematosus (SLE) presents to the Emergency Room (ER) with complaints of sharp retrosternal chest pain that worsens with deep breathing or lying down. She reports a 5-day history of low-grade fever, and listlessness and says she feels like she had the flu. A physical exam reveals tachycardia and a pleural friction rub. She was diagnosed with acute pericarditis.
Question #3:

Question 4
Scenario 4: Deep Venous Thrombosis (DVT)
An 81-year-old obese female patient who 48 hours post-op left total hip replacement. The patient has had severe nausea and vomiting and has been unable to go to physical therapy. Her mucus membranes are dry. The patient says the skin on her left leg is too tight. The exam reveals a swollen, tense, and red-colored calf.
