Q35 DL BCH4024/GMS5905 Spring 2022 Exаm ID 38: The cаrdiоtоnic sterоids, digitoxin аnd ouabain used in low dosages, help to increase the strength of the heartbeat in heart muscle cells. These drugs act by increasing the Na+ concentration in the cytosol and the cell compensates for the increased Na+ by activating Na+-Ca2+ exchanger resulting in a high concentration of Ca2+ in the sarcoplasmic reticulum (endoplasmic reticulum) of the heart muscle cell. Which of the following if inhibited would lead to an INCREASE in Na+ concentration in the cytosol of the heart muscle cell? In other words, what is the cellular target for these drugs?

Use the fоllоwing cаse study tо аnswer the next five questions. The community heаlth nurse is referred to the home of TB, a 48-year-old African American woman who smokes between 20-40 cigarettes daily for the last 30 years. She was discharged from the hospital five days ago following an upper respiratory infection. TB is divorced and works as a bookkeeper. Recently, a coworker was diagnosed with lung cancer, and TB admits this does frighten her, but "my grandfather smoked every day of his life, and he lived to the age of 95 years". She has tried several times to quit "cold turkey" without success. TB reports a history of depression, diabetes, and hypertension, for which she takes escitalopram 10 mg daily, metformin 1000 mg twice daily, enalapril 10 mg daily, and hydrochlorothiazide 25 mg daily, respectively. She has no known medication allergies and denies suffering from any other medical conditions. TB answers the door and walks slowly back to the sofa where she has been sitting. She is wearing a bathrobe at 2:30 pm but denies difficulty bathing and dressing. The nurse notes mild shortness of breath when TB walks the 15 feet from the door to the sofa. The nurse finds TB's lungs to be clear and diminished. Her pulse oximetry reading is 91% on room air while at rest. She has early clubbing on the fourth and fifth fingers of each hand. Her vital signs are as follows: BP 138/85; HR 103, oral temperature 37.1 degrees Celsius; respiratory rate 18 per minute. The nurse notes mild, 1+ non-pitting edema in each instep. She has never monitored her blood sugar at home, although she has been instructed to do so; but has a written prescription for a glucometer on her kitchen table. Her last hemoglobin A1C was 9.2%, one week ago, and her current BMI is 32. She follows a regular diet and eats in restaurants three times weekly. She denies decreased appetite and has a refrigerator full of fresh food, obtained by her sister yesterday. She denies any dysuria or urinary incontinence. Her urine is light yellow in color. Her last bowel movement was this morning, and she denies any difficulty passing stool. The nurse notes a moist, cream-colored discharge under the left breast in an area of 10x 2 cm. TB complains that the area both burns and itches and asks the nurse what to do about that problem. TB has not yet been told that a chest x-ray revealed a small, suspicious shadow in the right lung; she will follow up this issue with her primary provider. Question: which is the priority issue for the nurse during this visit?
