Textbook Question
Chapter 18, Problem 6CCS
54-Year-Old Female with a Defective Heart Valve
Dr. El-Sheikh is a 54-year-old Egyptian female who complains of weakness, fatigue, shortness of breath, chest pain, and dizziness. Her heart rate is 96 beats/min, and her blood pressure is 148/54 mm Hg. You notice that she nods her head with every heartbeat, and her radial pulse is very strong and abrupt. Her heart sounds are abnormal, with a long diastolic murmur at the right sternal margin in the second intercostal space.
Her doctor orders an echocardiogram, which shows that Dr. El-Sheikh has severe aortic regurgitation (backflow of blood through an incompetent valve) and an enlarged left ventricle.
6. NCLEX-STYLE Although Dr. El-Sheikh has a high systolic blood pressure, her heart rate is also high. This is most likely due to:
a. The Bainbridge reflex, caused by increased atrial filling
b. Parasympathetic activation
c. Excessive vagus nerve firing
d. Sympathetic stimulation

67-year-old diagnosed with an irregular heart rhythm. For the past month, she has been taking the following medications for management of her heart condition:
Digoxin 0.25mg once daily
Warfarin (Coumadin) 5mg once daily
During her F/U visit, you notice that Mrs. Pender has developed purpura on her arms & lower legs. When you ask her about these “purple spots” she states that she started noticing them about a week ago.
The provider has ordered serum LFTs & renal function tests
1.Based on the knowledge of drug pharmacokinetics, how should the nurse explain to the patient the possible cause of the purpura?
2.Mrs. Pender’s renal function test results show mild kidney impairment. What changes can the nurse anticipate regarding the patient’s medication regimen?
3.The patient asks the nurse, “Why did you have to check the function of my liver?” What is the most appropriate response by the nurse?
21) Female,35 years old. She came to the clinic because of persistent precordial pain for 2 days. Physical examination: frictional sounds can be heard in the fourth rib space on the left side of the sternum,which can still be
heard after holding the breath. The ECG suggests bow-dorsal downward elevation of the ST seament in the conventionai leads. What is her most likely clinical diagnosis?
A Acute myocardial infarction()
B Variant angina
C Acute pleurisy
D Acute pericarditis
E Acute pulmonary embolism
Provide ECG graphs for the following heart abnormalities;
1.Heart Attack
2.Cardiac hyperthrophy
3.Heart block

Mr. Garcia had a myocardial infarction. Explain what happened to his heart muscle and vascular system. What is a STEMII? 2. Mr. Garcia's chest pain resolved after two sublingual NTF at 3-minute intervals and 2 mg of IV morphine. In the cardiac catheterization lab he was "found to have a totally occluded distal right coronary artery and a 70% occlusion in the left circumflex coronary artery. The left anterior descending artery was patent. Angioplasty of the distal right coronary artery resulted in a patent infarct- related artery with near normal flow. A stent was left in place to stabilize the patient and limit infarct size. Left ventricular ejection fraction was normal at 42%, and a posterobasilar scar was present with hypokinesis." a. Explain angioplasty and stent placement. Define occluded occlusion. b. What is the purpose of this medical procedure?arrow_forward
