Hey, here is my answer to several questions:

Please solve the questions.


4.An analysis of EKG shows P waves occurin in the S-T segment. This would indicate ectopic beats originating in the
-atria
A-V node
lower potion of bundle of His----anwer
upper " " " " "
This question is testing the conduction of heart, specifically the concept of P wave--the depolarization of atrium, QRS---depolarization of ventricle, ST segment---repolarization of ventricle. If a P wave appears in ST segment, means there is a ectopic beats during repolarization period of ventricle. The difference btw upper and lower of His bundle is upper portion depolarization usually happens during ventricle depolarization. So the answer is "lower portion of His bundle".

each of the following mechanisms is actoveted in response to heat except one. Which is the exception?
Panting
sweating
loss of appetite--answer
cutaneous vasodilation
increase in voluntary activity-
This question is testing the concept of "appetite". Appetite is controlled by hypothelamus. Cutaneous vasodilation happens in exercise which is heart-related, so is "increase voluntary activity".

cutaneous vasodilation
increase in voluntary activity-
This question is testing the concept of "appetite". Appetite is controlled by hypothelamus. Cutaneous vasodilation happens in exercise which is heart-related, so is "increase voluntary activity".

increase in temp = loss in appetite
so why do u think , loss of appetite is the answer, the question might be on hypothalamic activity

I dunno wat the right ans is, but guess......the last option is the ans.(pls correct me with explaination)

 

[chahatai]

Increase body temp in physiological range won't change the appetite. After strenuous exercise, we may loss our appetite due to dehydration, not directly from increase of body temp. This question is asking the heart-related factor, so the answer should be loss of appetite which is controlled by hypothalamus.

hey all

i have a doubt in dental anatomy
the only teeth with MCR>DCR
permanent maxillary 1st premolar(sure)
primary maxillary canine(sure)
primary mandibular canines.(not sure)???

hope i am correct, someone plz confirm

thanks in advance.

 

[wadent]

hey question 2 :
is increase voluntary action ,,,,, because increase voluntary action is in response to cold and here they r sayin except one ..hope this is clear ...
peace !

 

[chahatai]

I have to say that this question is really vague and dumb. You won't see such questions in a real exam. The questions from real exam are very clear. Move on, you have other important questions to do.

hey question 2 :
is increase voluntary action ,,,,, because increase voluntary action is in response to cold and here they r sayin except one ..hope this is clear ...
peace !

thank you pbkal! I'm still not clear abt the da stuff.
Hey chahatai, can you pls solve the below question with the explanation? thank you.
A dehydrated patient, as a result of severe vomiting following over-use of narcotic analgesic, might present with which of the following symptoms?
-an increased pulse rate- answer
-an increased blood pressure
-facial edema
-distended neck veins
-desire to urinate contantly

-an increased pulse rate-
-an increased blood pressure--answer
-facial edema
-distended neck veins
-desire to urinate contantly

This question is testing the pathophysiology of hypovolumic shock. If the body fluid is lost too much, it is called hypovolumic shock. When this happens to a patient, patient's body will compensate by stimulating kidney to secret Renin. Renin can activate Renin-Angiotensin_ALdersterone system. So kidney urine formation decrease (by the action of aldersterone). Angiotensin II increase blood pressure by increase the peripheral resistance(answer B).. Increased BP can cause heart slow down by reflex.

It is easy to exclude facial edema and distended neck vein by common sense.

 

[bestluck]

i think i got the logic-
ages for completion of calcification of permanent teeth-
crown completion in max and mand incisors by ages 4-5yrs.
'' '' '' '' premolars by 6-7yrs
'' '' '' '' 1st molars by 21/2-3yrs
'' '' '' '' 2nd molars by 7-8yrs
'' '' '' '' 3rd molars by 12-16yrs.

so,according to this,incisors and also permanent 1st molars r least affected if tetracycline is given at 5-6yrs age.

pls correct if im wrong.....

hi please can some one tell the only answer for this and why it should be one answer right ? plz

oh ok i thought it's suppose to be increase pulse rate (tachycardia)...!!!!!!!!!!!!!!!!

ok then i have another quest.
each of the followin combinations list the name of the hormone its chemical type and its major tissue organ EXCEPT one:

a. acth stroid adrenal cortx
b.thyrotropin glycoprotein ant.piutary
c vasopresin peptide post. pitutary


is the answer (a) ??????????????




2. A pregnant woman spontanously abort a fetus @ 24 weeks gestation.the woman and her husband are both Asian descent,and both have a mild microcytic anemia. hemoglobin electrophoresis of blood taken from the heart of the fetus has tetramers composed entrly of gamma-globulin chains.
which of the following types of hemoglobinopathy do the parents most likely have ??

a.hemoglobin H (hbH) DISEASE

In multiple myeloma is there increase in acid phosphatase?
Please reply.

I think the increase of acid phophotase will be seen in the prostrate cancer and its considered to be one of the markers along with the PSA. Hope it helps. Correct me if needed.

i think for the first question is choice A becoz the ACTH is not by the adrenal cortex and its not the steroid type.
for the second, I think the answer is sickle cell trait. Since, it has all the gamma globulin tetramers alpha and beta thalassemia are ruled out. Also, its been inherited. I'm not sure for the answers. Anyway I tried my best. correct me for the mistakes. thanks.

hey chahatai,
thank you that was a good one! since the answer keys said the choice A is rt and I made the some reasoning as there's been vomiting, there's a less bld volume thats followed by the lowering of the BP and hence the increased pulse rate to elevate the BP. You think thats relevant or no? Pls do explain.

e.sickel cell anemia
I think I was wrong abt the previous answer. pardon me. I think the disease wud the choice a. since the history says they are the asian decent and has 4 gamma tetramers. I think the choice is A. Pls do correct me for mistakes.

 

[chahatai]

Most microcytic anemia are caused by either iron deficient anemia or thalassemia. In this case, since there is no choice for iron deficient anemia, so the answer should between alfa or beta thelassemia.

So which one is the answer? alpha or beta? the answer should be beta. Why? because of the baby's hemoglobin type. A healthy infant's hemoglobin should be two beta and two gamma. In this case, all 4 hemoglobin subunits are gamma. This means the infants body can not make beta chain. So his/her parents must have beta chain gene mutation. So the answer should be beta thelassemia.

Correct me if my answer is wrong.

[chahatai]

Thelassemia can happen to any race. Most likely happen to people from south Asia, such as south of india, Sirilanka, Maldev, Thailand. The reason I know this is because I have a friend who has this disease.

Is this answer given by ADA? If not(, I think the choice a is not right. If it is given by ADA, I don't know how to explain it. My be ADA is wrong too? hehe. Could be.

[colours99]

Answer is alfa thalassemia.

From Wikipedia:
"The α thalassemias involve the genes HBA1[4] and HBA2,[5] inherited in a Mendelian recessive fashion. It is also connected to the deletion of the 16p chromosome. α thalassemias result in decreased alpha-globin production, therefore fewer alpha-globin chains are produced, resulting in an excess of β chains in adults and excess γ chains in newborns. The excess β chains form unstable tetramers (called Hemoglobin H or HbH of 4 beta chains) which have abnormal oxygen dissociation curves."

Beta thalassemias are due to mutations in the HBB gene on chromosome 11,[6] also inherited in an autosomal-recessive fashion. The severity of the disease depends on the nature of the mutation. Mutations are characterized as (βo or β thalassemia major) if they prevent any formation of β chains (which is the most severe form of beta Thalassemia); they are characterized as (β+ or β thalassemia intermedia) if they allow some β chain formation to occur. In either case there is a relative excess of α chains, but these do not form tetramers: rather, they bind to the red blood cell membranes, producing membrane damage, and at high concentrations they form toxic aggregates.

About the dehydration Q , is the answer not Increased pulse rate?

Most microcytic anemia are caused by either iron deficient anemia or thalassemia. In this case, since there is no choice for iron deficient anemia, so the answer should between alfa or beta thelassemia.

So which one is the answer? alpha or beta? the answer should be beta. Why? because of the baby's hemoglobin type. A healthy infant's hemoglobin should be two beta and two gamma. In this case, all 4 hemoglobin subunits are gamma. This means the infants body can not make beta chain. So his/her parents must have beta chain gene mutation. So the answer should be beta thelassemia.

loss of appetite--answer
cutaneous vasodilation
increase in voluntary activity-
This question is testing the concept of "appetite". Appetite is controlled by hypothelamus. Cutaneous vasodilation happens in exercise which is heart-related, so is "increase voluntary activity".

increase in temp = loss in appetite
so why do u think , loss of appetite is the answer, the question might be on hypothalamic activity

I dunno wat the right ans is, but guess......the last option is the ans.(pls correct me with explaination)

hi the answer is vasodilation I think I've seen it in one released i'm sure about it !!!

aquternaly amonium compound
gluteraldehide
anionic detergent

hi any one can answer this please essential substans to act as amphipathic molecule
polar non polar --- answer
polar negative charged
nonpolar posative charge cyclic hydrophilic
branched hydrophilic

expln :Amphipathic molecules containing both are mostly lipid-like (hydrophobic) in structure, but at one end have a region that is polar or ionic (hydrophilic).These molecules are mostly lipid-like (hydrophobic) in structure, but at one end have a region that is polar or ionic (hydrophilic).
hydrophilic = head , lipid portion is called tail.

else please correct me with expln. thanks

which of the following is normally seen in a 23 yr old man....

1--hematocrit----45 %
2--venous blood ph of 7.2
3-wbc count of 10000/ mm3
4--rbc of 7,000,000/mm3
5--pulse pressure of 80 mm of hg

ans is 1. can someone explain why it is not 3???

Since the question asked abt the normal criteria, I wud probably go with the hemotocrit values instead of the choice3. Ususally the WBC count wud be the pathological index. I hope I make sense. If not pls explain.

hey best luck,
what is the best way to prevent disease transmission in dental office?
sterilization
universal precaution-answer
barrier techniq
best way to sterilize dental burs without corrosion using?
unsaturated vapor
quatenary ammonium compound
ultrasound cleansing
autoclaving-answer
iodophore
what is more effetive in disinfecting skin prior to obtaining a blood specimen for culture by using
70% ethanol-answer
2% tincture of iodineor
quatenary ammonium compound
gluteraldehyde
anionic detergent
If the 70% ethanol is one among the choice I wud go with that.
in evaluatin EKG PR increase will represent-
slow conduction impulse throu S-A
rapid conduction through ventricle
slow repolarization of atria
slow conduction impulse through AV-answer
rapid conducion thro atria
The P is the atrial depolarization, PR segment is the time interval for the AV node to get depolarized and impulse comes from the SA node. So, the PR inccrease will be the choice 4.
QRS is the ventricular depolarization. Correct me if I'm wrong. thanks

thanks dentgod why did you chose universal precaution can you tell me you sourse? i thought it's either barier precaution or sterilization any one confirm???
and about autoclaving it is in the answer key but i think it will get corrusion right ??

about pulse rate it mean increase no of pulse per minute not increase the time between pulses still can't get it 🙁thanks again

Autoclave causes corrosion.So the answer shouldn't be autoclave right?Instead Ethylene oxide or Dri-clave is used to sterilize when the corrosion is of concern.

here,PR is not pulse rate.
question says ECG-electrocardiogram,which has P,Q,R,S,T .............
i hope now u got it....
