CJ is a 16-year-old high school student who is in the clinic for a sports physical prior to beginning basketball practice. He has no known significant medical history, takes no medications, and has no allergies. Subjective data reveal only that CJ is short of breath earlier than most boys on the team. He attributes this to needing to get into better physical condition. The physical is unremarkable except for a grade III systolic murmur heard over the entire precordium. An echocardiogram and cardiac catheterization reveal a ventricular septal defect (VSD) with moderate pulmonary hypertension.
Discussion Questions:
1. A VSD is usually an acyanotic defect. Why is this?
2. What is the mechanism of pulmonary hypertension? What may result if it is prolonged?
3. What other disorders besides VSD can produce a systolic murmur? How can character of the murmur and pattern of radiation be used to differentiate among the etiologic factors?
4. Is it necessary to close a VSD? What are the common complications of untreated VSD?
VSD known as ventricular septal defect is a heart condition that caused by trauma, surgery or a heart attack in adults or it's congenital (present at birth). It is characterised by an abnormal connection or hole between the lower chambers of the heart.
A VSD is usually an acyanotic defect. Why is this?
Ventricular septal defect is usually an acyanotic defect or a non-cyanotic heart defect because in it,the level of oxygen in the body is not affected, in VSD blood is shunted that's is blood flows from the left side of the heart to the right side of the heart.
This is most often as a result of a structural defect, a hole in the intraventricular septum.
What is the mechanism of pulmonary hypertension? What may result if it is prolonged?
When there is undue or excessive stress on the heart especially the heart muscles,the pulmonary arteries also gain high pressure and this high pressure results in an acute injury to the capillary walls of the alveolar and subsequent resulting to edema.
When it is prolonged, it can cause the thickening of the thickening of the walls of the alveolar capillary membrane irreversibly and thereby compromising the function of the lungs.
What other disorders besides VSD can produce a systolic murmur? How can character of the murmur and pattern of radiation be used to differentiate among the etiologic factors?
Other disorders beside VSD that can produce a systolic murmur are;
Pulmonary infundibular stenosis,tetralogy of Fallot, atrial septal defect, valvular pulmonary stenosis,aortic sclerosis, hypertrophic obstructive cardiomyopathy, supravalvular aortic stenosis.
The character of the murmur can be used to differentiate among the etiologic factors by taking into consideration whether the heart murmur is functional/physiologic(primarily due to a physiologic condition outside the heart),murmurs due to structural defect in the heart itself,the functional murmurs which are benign,pathologic murmurs are as a result of a problems within the heart like abnormal passages or leaking of valves, systolic or diastolic murmur is as a result bif the timing of the murmur(the part of the heartbeat they are heard from).
Is it necessary to close a VSD? What are the common complications of untreated VSD?
Small ventricular septal defect may close on their own as they are likely to cause no problem, however, medium or large ventricular septal defect may pose a problem and therefore will require a surgical intervention/repair early enough inorder to prevent complications.
Some of the common complications of ventricular septal defect are;
Heart valve problem,poor growth and development,lung problems, irregular heart rhythms(arrhythmias), heart failure, pulmonary hypertension,lung damage.

I don’t understand this question.
Answer:
I think the answer is A
Explanation:
Mr. Roberson, age 42, is diagnosed with essential hypertension. His blood pressure has been ranging between 150 and 184 mm Hg systolic and 94 and 110 mm Hg diastolic. His average blood pressure is 154/94 mm Hg. There is a positive family history of hypertension and stroke on both sides of the family. He is married, with two school-age children, and works full-time as a local truck driver for a seafood company. His elevated blood pressure was found during a routine physical examination. He has no other symptoms. Mr. Roberson is to begin taking atenolol, 50 mg daily, and hydrochlorothiazide, 50 mg daily.
Required:
a. How do each of these drugs work to control blood pressure?
b. Why are both drugs prescribed at this time?
c. What patient teaching is important with these medications? (Include teaching about potential adverse effects.)
Answer:
a. Atenolol is a beta-blocker, while Hydrochlorothiazide is a diuretic.
b. Atenolol and Hydrochlorothiazide can be used together to decrease the blood pressure and to slow the heart rate down.
c. The patient needs to have into consideration that both medications may cause irregular heartbeats, dizziness, weakness and fainting.
Explanation:
Atenolol is a beta-blocker, it means that this drug slows down the heart rate by changing how the body responds to nerve impulses, which enhances the pumping of blood. Moreover, Hydrochlorothiazide is a diuretic or 'water pills' drug that can be used to treat edema conditions (i.e., excess fluid in tissues), thereby enhancing blood pressure that can damage the heart. It has been shown that the combination of both drugs may decrease the blood pressure and the incidence of hypertension.

The closure of which valves causes the sound lub and dup
Answer:
The sound "lub" is produced by the closure of the atrioventricular valves (mitral and tricuspid valves) while the sound "dub" is produced by the closure of the semilunar valves (aortic and pulmonic valves).
Explanation:
The question above is related to the body's circulatory system. The heart is pumping non-stop in order to deliver oxygenated blood to the body. Blood follows a particular flow once it enters and leaves the heart. Part of that flow produces the "lub" and "dub" sound. These sounds are produced by the two valves that ensure the blood follows a correct path. These are the atrioventricular valves and the semilunar valves.
The atrioventricular valves are located in the middle of the atria and the ventricles while the semilunar valves are located at the bottom of the vessels. Once the blood flows towards the atrioventricular valves and they close, it produces the "lub" sound, also called the first heart sound. When the blood flows towards the semilunar valves and they close, it produces the "dub" sound, also called the second heart sound.

Which is not a type of contamination in a food establishment?
A) Biological
B) Environmental
C) Chemical
D) Physical
Answer: Environmental
Explanation:
The three contamination's in food handling are biological, physical, and chemical
The correct answer is B. Environmental.
Explanation
Food contamination is a term that refers to the action in which food is exposed to a contaminant or dangerous substance that is capable of producing a negative effect on the health of the consumer.
To study food contamination, three main categories have been established are physical, which refers to all kinds of foreign objects that can contaminate food and can cause injuries or choking to the consumer such as bones, crystals, or others. The second category is chemicals, which refers to all kinds of toxic substances that can contaminate food such as cleaning products, poison, or others. The third category is biological, which refers to contamination caused by contact with living beings such as insects, rodents, birds, microorganisms, among others.
According to the above, the correct answer is B. "Environmental" because this is not a category to study food contaminants.

A-Floxin
B-Cardura
C-Vibramycin
D-Zovirax
Answer:
The antibiotic used to fight the body's bacteria and classified as a quinolone is Floxin.
Explanation:
Floxin is the commercial name of Ofloxacin, a 2nd generation quinolone used in the treatment of infections by gram positive and gram negative germs. Its mechanism of action is to inhibit enzymes important for bacterial development, such as DNA gyrase and Topoisomerase IV.
Ofloxacin can be used for infections of the eyes, ears, skin and genitourinary system, including some sexually transmitted infections. Other 2nd generation quinolones are ciprofloxacin and norfloxacin.
Ofloxacin comes in tablets form, so it is only administered orally.
The other options are not correct because:

Cardiopulmonary resuscitation is a first aid technique for individuals in cardiac arrest that involves __________.
A.
a defibrillator and rescue breathing
B.
rescue breathing and chest compressions
C.
a defibrillator and chest compressions
D.
chest compressions and adrenaline injections
Answer:
Cardiopulmonary resuscitation involves rescue breathing and chest compression (option B).
Explanation:
Cardiopulmonary resuscitation (CPR) is a procedure used in cases of cardiorespiratory dysfunction or arrest, so it is necessary to ensure proper breathing and cardiovascular function.
There are two levels of CPR:
Basic CPR involves rescue breathing and chest compressions. It is a first aid technique that can be used until the patient can be taken to a hospital.Advanced CPR employs the use of drugs and instruments, such as a defibrillator monitor. This procedure is performed by qualified personnel, in mobile units or in hospital emergency rooms.First aid in case of cardiac arrest depends on both respiratory resuscitation —rescue breathing— and chest compression.
The other options are not valid, because they all involve advanced CPR techniques and not first aid, and the options a defibrillator and chest compressions (C) and defibrillator and chest compressions (D) leave out breathing rescue.
