1st one I would say E- get the Spanish interpreter. The patient is able to refuse information regarding his condition if he chooses however is family can't make that decision for him.

3rd one- The cross section looks like its in the cervical spinal cord. I'm also thinking corticospinal because motor impairment. We knew CST crosses at the medulla, and since the symptoms are on the right said I would say E.

8. answer: C. PT time is normal and measures the extrinsic pathway, aPTT time is increased so you know the problem is with the intrinsic pathway. Since there is a problem with coagulation you can rule out E, D and B is unrelated to this. C5a has to do with neutrophil chemotaxis is inflammation. Pre-kallikrein forms Kallikrein with the help of Hageman factor (XIIa) which is from the intrinsic pathway.

Q14 is E. You have to know what patient wishes are.
Q 18 is A. I'm not sure. Pt. has polyuria, polydypsia. I think the diagnosis is metabolic syndrome.
Spinal cord section is E. Right corticospinal tract is damaged.
Q 8 is c, Kallekrien formation. As APTT is increased, there's a problem in intrinsic pathway. Check coagulation pathway chart in first aid. You will figure it out.

Default cvs doubt

An investigator is studying the regulation of pulmonary lymphatic flow using an animal model. Catheters are implanted in the femoral vein, pulmonary artery, and main lymphatic vessel draining the lungs in anesthetized, intubated, mechanically ventilated animals. Drugs may be injected directly into the pulmonary artery catheter and inspired gas mixtures altered at the ventilator; timed collection of lymph from the catheters is used to calculate lymphatic flow. Which of the following interventions will most likely increase the flow of pulmonary lymph in these animals?
A.Administration of endothelin-1 into the pulmonary artery
B.Administration of phenylephrine into the pulmonary artery
C.Decreasing the inspired oxygen concentration from 21% to 10%
D.Increasing the inspired carbon dioxide concentration from 0.3% to 3%
E.Intravenous infusion of 0.9% saline for 5 minutes
F.Intravenous infusion of 20% albumin solution (20 g/100 mL saline) for 5 minutes

  • The answer is e. The explanation is in the forum questions above. It said that saline is the only choice in which the blood flow increased leading to increased lymphatic flow

In u world there is a formula by Laplace.
It's the rate of flow through a vessel= cross sectional area × flow velocity.

It is unbalanced chromosomal rearrangement.
Specifically it is robertsonian translocation. which is seen in young females and causes related abortions and if they child is born it has many abnormalities. It's given in kaplan genetics.

Post Hi

Logged in as sashabeliimd
Title: Sorry, this is from form 7, but cannot choise a correct answer,
A pharmacologist discovers a new fungal metabolite with unusual antimicrobial properties. It naturally concentrates in the endosomes, lysosomes, and phagolysosomes of cells and directly kills microorganisms( eg, Mycobacterium tuberculosis) that are normally resistant to degradation in the phagolysosomes. The metabolite has the undesirable effect of increasing the pH within phagolysosomes. Which of the following processes will be primarily affected?

Class I MHC molecule peptide loading
Class II MHC molecule peptide loading
Peptide binding to T-lymphocyte receptor alpha betta
Peptide binding to T-lymphocyte receptor Gama sigma

one mark, answer a is incorrect

For the woman with osteoporosis wouldn't alcohol increase risk of falls and fractures? And I thought dumbbells based exercise or similar would be considered weight bearing.. Is just a walk also considered that?

An 18-month-old boy is brought to the emergency department because of lethargy for 3 hours. He has not eaten well for the past 24 hours.
He had cardiorespiratory arrest associated with hypoglycemia after an episode of diarrhea 10 months ago. On arrival, he is unresponsive. His
temperature is 37“C (98.6“F), pulse is 140/min, respirations are 25/min, and blood pressure is 100/60 mm Hg. Physical examination shows
hepatomegaly. Laboratory studies show:
Serum
Glucose decreased
Ketones decreased
Camitine decreased
Urine
Ketones decreased
Dicarboxylic acids present


Following intravenous administration of glucose, he becomes responsive. Medium-chain triglycerides are administered daily for 6 months. At a
follow-up examination, his serum glucose concentration is within the reference range. A de¿ciency of which of the following enzymes is the
most likely cause of these ¿ndings?
A) Glucose 6-phosphatase
B) HMG-CoAIyase
C) Homwone-sensitive lipase
D) Lipoproteinlipase
E) Long-chain acyl-CoA dehydrogenase
F) Phosphoenolpyruvate carboxykinase


F is wrong

Dicarboxylic acids present


Following intravenous administration of glucose, he becomes responsive. Medium-chain triglycerides are administered daily for 6 months. At a
follow-up examination, his serum glucose concentration is within the reference range. A de¿ciency of which of the following enzymes is the
most likely cause of these ¿ndings?
A) Glucose 6-phosphatase
B) HMG-CoAIyase
C) Homwone-sensitive lipase
D) Lipoproteinlipase
E) Long-chain acyl-CoA dehydrogenase
F) Phosphoenolpyruvate carboxykinase


F is wrong
If you wanna see a normal answer, than write quetion on original way, if you short some words or phrase, you may losing sense!!! Please dont be a some lazy and type complete quetion if you realy require response.

Correct Answer Endocrinology
A 38 yo woman comes to the physician because of a 10 week history of epigasric pain and frequent stools. She has had two episodes of renal calculi during the past 2 years. Physical examination shows multiple superficial lipomata and mild epigastric tenderness. Upper endoscopy shows two large nonbleeding duodenal ulcers. Her gastric pH is 2.3 and serum gastrin concentration obtained immediately after the procedure is 2000pg'mL Norma less than 100. Proton pump inhibitor therapy is begun. Measurement of which of the following is the most appropiate next step in management?

Serum calcium concentration
Serum cortisol concentration
Serum tissue tranglutaminas activity
Stool alpha antitrypsin concentriation
Urine 5 hydroxyindolacetic acid concentration wronggggggg

Epigastric pain plus increased serum gastrin, and duodenal ulcers mimic Gastrinoma
Renal calculi give a sign of parathyroid gland hyperfuncion, which most common is a parathyroid adenoma, and in combination form a MEN 1 endocrine neplasia

Answer will be increased calcium

Im guessing its A or C but not sure.
Choice A ( closed closed open )

While swallowing they will be CLOSED
- Normal function; prevents food from going into trachea instead of esophagus.

Immediately after Laryngeal Irritation CLOSED
- These is a REFLEX to prevent aspiration of foreign body from going further into trachea.

While Coughing OPEN
- To help expel the foreign body out.

These are the same sequence (mechanism) of events that will occur in a Pt. involved in the Cinnamon Challenge.

I put CLOSED OPEN OPEN and was incorrect. what is the correct one?. thanks

I saw an earlier post say closed, open, closed is correct but I put that and it is incorrect.

--------------------------------------------------

its CLOSED during swallowing, OPEN AND OPEN.

i got it wrong because it implied that the patient was laughing while eating THEY ASKED what was the sequence IN THE patient, so i guess he would have had OPEN vocal cords while swallowing (normally is closed), so actually they were meaning what happens NORMALLY.

An 85-year-old woman is diagnosed with a fracture of the right femur and begins treatment with morphine by patient-controlled analgesic pump. Three days later, her respirations are 6/min. Physical examination shows pinpoint pupils. Her serum creatinine concentration is 1.8 mg/dL. Which of the following best explains this patient's clinical deterioration after the initiation of morphine therapy?
A) Chronic dosing of morphine decreases its bioavailability
B) Morphine bioavailability increases with chronic dosing
C) Morphine downregulates mu-opioid receptors with chronic dosing
D) Morphine inhibits its own metabolism
E) Morphine is metabolized to active metabolites that accumulate
1-11 is E. and 1-4 is D. 1-2 I got it wrong, thinking maybe you won't see macrophages in a week?? but haven't really found the answer...

Default help?

I reviewed the previous post and couldn't find these answers:

1.A 49-year-old woman with breast cancer develops increased numbness of both
hands and feet during the 3-week interval between her third and fourth rounds of
chemotherapy. Sensation to pinprick and fine touch is decreased over the hands,
wrists, ankles, and feet. The physician suspects that this distribution of sensory loss
is most likely an adverse effect of chemotherapeutic agents. Which of the following
is most likely disrupted in this patient as a result of the chemotherapy?
A) Microtubules for axonal transport
B) Myelin sheaths for saltatory conduction of action potentials
C) Neurofilaments for structural support of axons
D) Sodium channels for membrane depolarization
E) Synaptic vesicles for synaptic transmission

2. 18-year-old woman comes to the physician because of progressive fever, general
malaise, and blood in her urine since she began oral antibiotic therapy for a urinary
tract infection 5 days ago. She also has a 3-day history of a rash. Her temperature is
38°C (100.4°F), pulse is 75/min, respirations are 12/min, and blood pressure is
125/80 mm Hg. Physical examination shows a petechial rash over the chest, back,
and upper and lower extremities. Urinalysis shows:
Blood 3+
Protein 1+
Leukocytes 150/hpf
Eosinophils 30%
Which of the following is the most likely diagnosis?
A) Acute tubular necrosis
B) Glomerulonephritis
C) IgA nephropathy
D) Interstitial nephritis
E) Papillary necrosis

3A 2-year-old boy is brought to the physician because of developmental delay. There
is a history of hearing loss in his mother and delayed speech in his older sister. His
maternal uncle had stroke-like episodes at the age of 25 years. Physical
examination shows ophthalmoplegia and hypotonia. His serum lactic acid
concentration is increased. Which of the following best explains the findings in this
family?
A) Autosomal dominant inheritance
B) Decreased penetrance
C) Heteroplasmy
D) Imprinting
E) X-linked recessive inheritance

4.A 54-year-old woman is admitted to the hospital with an acute myocardial infarction.
At the time of admission, she has no physical signs of heart failure, and no heart
murmur is detected. Two days later, she becomes acutely short of breath and
diaphoretic. Her pulse is 100/min, respirations are 24/min, and blood pressure is
160/98 mm Hg. Crackles are heard bilaterally throughout both lung fields on
auscultation of the chest. A murmur is heard on cardiac examination. Which of the
following is the most likely murmur in this patient?
A) Grade 2/6, diastolic decrescendo murmur heard best over the second and
third left intercostal spaces
B) Grade 2/6, rumbling diastolic murmur heard best 2 cm left of the sternal
border at the fourth left intercostal space
C) Grade 3/6, crescendo-decrescendo systolic murmur heard best at the
second left intercostal space
D) Grade 4/6, continuous systolic and diastolic murmur heard best along the
left sternal border
E) Grade 4/6, holosystolic murmur heard best over the lower left sternal border
and the cardiac apex

5.A 70-year-old woman is found to have persistent fever despite intravenous broad spectrum antibiotic therapy 3 days after undergoing operative excision of the anterior pelvic organs for recurrent cervical carcinoma. Her temperature is
38.5°C (101.3°F). Physical examination shows the presence of a central venous catheter that was placed on the day of the operation. There is also a well healing
abdominal wound without erythema and with two drains in place. Blood cultures
and cultures of the tip of the central catheter on a sheep blood agar plate grow the organism shown in the photograph. A Gram stain of one of the colonies shows 4-μm, elliptical, purple, budding organisms.
Which of the following is the most likely causal organism?
A) Candida
albicans
B) Cryptococcus
neoformans
C) Escherichia coli
D) Sporothrix
schenckii
E) Staphylococcus aureus.

Thanks, for your help I found this test very hard, didn't do bad but have these couple of questions that don't seem to make sense.

I have also attached few questions if anyone got these right plz be kind and share your thoughts. Thank you

1) Guy who has allergies each spring, what to treat with for SHORT term relief? I picked Nictonic choligneric antagonist which was wrong. ?? I did not pick B agonist b/c that is for severe cases like asthma not just allergies. What do u guys think?

2) An animal study is conducted to assess the effects of smoking on pulmonary defense and maintenance mechanisms. For 1 week, normal
male rats are exposed to levels of cigarette smoke comparable to those encountered by humans who smoke cigarettes. Results of
pulmonary testing are compared with baseline levels obtained the week before the smoke exposure. Which of the following sets of changes

Mucus Production and Secretion up/down

Alveolar Macrophage Function up/down

Activity of Airway Cilia up/down

3) Newborn has hypothyrodism, the question asked what crossed the placetal barrier from mother that caused this??
TSH, TRH, THYROGLOBULIN, IODINE, T4. Can someone plz explain this? I picked TSH b/c it will be high in mom with hypothyroid.

4) 20 year old woman comes severe dysuria and painful vulvar rash for 2 days, what is the organism ?? How do u know exactly which one it is here?? Iknow HPV causes vulvar infectinos but it is painless, was very lost here.

5) Guy has prostate CA , undergoes prostatectomy , what structure is at risk for injury during removal of prostate? I put penile urethra which was wrong.

6)A 15-year-old girl is brought to the emergency department 12 hours after she ingested an entire bottle (100 capsules) of vitamin D in a suicide attempt , now her serum Ca is 10.4 . What is the MOA by which her calcium increased? I put increased 1 hydroxylase activity in kidney. Why is that wrong anyone know??

7) Fanconics syndrome, what are the Amino Acids, HC03, Phosphate and Glucose levels ? Increased or decreased for each.
7-H all decreased i got it right

Therefore it is D, partial agonist at angiotensin II receptors.

So by elimination, you are left with the silly macrophage option :|

Btw, Robbins does say IL 1, IL6 and TNF alpha are secreted in the late phase of type 1 hypersensitivity, but it is secreted by monocytes and neutrophils

Sensations of joint position, pain, and temperature in the lower extremities are normal. Which of the following is the most likely cause of the findings in this patient?
A) Acute peripheral neuropathy
B) Degeneration of motoneurons of the lumbar cord
C) Demyelination of the corticospinal pathways
D) Loss of afferent la axons innervating muscle spindles
E) Myotonic muscular dystrophy

Seems to be LMN lesion. Is C the correct answer? What is her dx? Cannot be poliomyelitis virus infection.

That's my logic, I probably would have gone with B on the exam, then cursed myself later.

ghrelin inc. in P.wili,
Leptin receptor defective= lipodystrophy

Dude, are you sure?
I think E is correct. It makes the most sense and also someone else said they got it right and it was correct. Think about it: this question is testing you 'do you know when precocious puberty begins?' <8yo is precocious. Done.
B would be the next best, but the question asks what is the initial step.
