| single | The buttocks are the preferred site for administration of the intramuscular injection.
The muscles (gluteal) of this area are thick and are utilized frequently in daily activities, thus causing complete absorption of drugs.
To give the injection at the proper site, the gluteal region can be divided into four quadrant -
i) Superomedial (upper inner quadrant)
ii) Superolateral (upper outer quadrant)
iii) Inferomedial (lower inner quadrant)
iv) Inferolateral (lower outer quadrant)
The proper location for an injection is the upper outer quadrant (superolateral) because this is the location where there is least possibility of hitting bone, large blood vessels or the sciatic nerve. | Pharmacology | null |

115e3890-5181-4e09-9669-2aff536477ad | An 8-year-old child is evaluated by the pediatrician, who notes small cafe-au-lait spots on the child's torso. In addition, on close inspection of the eyes, the presence of Lisch nodules is noted. The patient is eventually diagnosed with neurofibromatosis type 1. The protein that is mutated in this disorder normally does which of the following functions? | Activates the GTPase activity of Ras | Cleaves cellular proteins during apoptosis | Functions as a cell cycle checkpoint regulator | Promotes angiogenesis | 0a
| multi | The normal function of NF1 is to promote the intrinsic GTPase function of the RAS oncogene. Mechanism:- RAS has an intrinsic GTPase activity that is accelerated by GTPase-activating proteins (GAPs), which bind to active RAS and augment its GTPase activity by more than 1000-fold, thereby terminating signal transduction. Thus, GAPs prevent uncontrolled RAS activity. When the Ras protein is bound to GTP, the growth-promoting function of the molecule is "ON". On hydrolysis of the GTP to GDP, Ras is conveed to an inactive state. GAPs (GTPase Activating Proteins), such as NF-1, suppress cell growth by stimulating GTP hydrolysis. Disabling mutations of neurofibromin 1, a GAP (GTPase-activating protein) encoded by the NF1 gene, are associated with the inherited cancer syndrome familial neurofibromatosis type 1. NF1 is therefore an example of a tumor suppressor gene that acts through negative regulation of RAS signaling (inhibitor of RAS/MAPK signaling). Other Options:- Caspases function to cleave cellular proteins once apoptosis is triggered Vascular endothelial growth factor promotes tumor angiogenesis RB and TP53 function as cell cycle checkpoint regulators | Pathology | Genetic Basics Of Carcinogenesis |

071b822d-0b92-4499-bfa3-710331047cae | A 23-year-old female maid was making a bed in a hotel bedroom. As she straightened the sheet by running her right hand over the surface with her fingers extended, she caught the end of the index finger in a fold. She experienced a sudden, severe pain over the base of the terminal phalanx. Several hours later when the pain had diminished, she noted that the end of her right index finger was swollen and she could not completely extend the terminal interphalangeal joint. Which one of the following structures within the digit was most likely injured? | The proper palmar digital branch of the median nerve | The vinculum longa | The insertion of the tendon of the extensor digitorum onto the base of the distal phalanx | The insertion of the flexor digitorum profundus tendon | 2c
| single | The contraction of the extensor mechanism produces extension of the distal interphalangeal joint. When it is torn from the distal phalanx, the digit is pulled into flexion by the flexor digitorum profundus.

| single | Ans. (b) APO B 100Ref: Harper's Biochemistry, 30th ed. pg. 254* The low-density-lipoprotein (LDL) receptor is a cell- surface protein that plays an important part in the metabolism of cholesterol by mediating the uptake of LDL from plasma into cells.* Although LDL particles bind to the LDL receptor through their apolipoprotein B (apo B) and apolipoprotein E (apo E) moieties, other apo E-containing particles, like chylomicron remnants, are not dependent on the LDL receptor for uptake into cells.* ApoB100 levels are associated with coronary heart disease, and are even a better predictor of it than is LDL level. A simple way of explaining this observation is to use the idea that ApoB-100 reflects lipoprotein particle number (independent of their cholesterol content). In this way, one can infer that the number of ApoB100- containing lipoprotein particles is a determinant of atherosclerosis and heart disease.* Most important apoprotein in HDL: Apo A-I* Most important apoprotein in chylomicrons: Apo B-48, E* Most important apoprotein in LDL, IDL, VLDL: Apo B-100* Apo protein for IDL - Apo B 100 and E | Biochemistry | Lipids |

| single | Ans. is A Centriacinar Types of emphysema 1) Centriacinar (centrilobular) emphysema o Centriacinar emphysema is the most common type of emphysema seen clinically. It is chracterized by involvement of respiratory bronchioles, i.e. central (proximal) part of the acinus. Occurs predominantly in heavy smokers and usually coexists with chronic bronchitis. 2) Panacinar (Panlobular) emphysema o The acini are uniformly enlarged from the level of the respiratory bronchiole to the terminal blind alveoli. This type of emphysema is associated with al-antitrypsin deficiency. 3) Distal acinar (Paraseptal) emphysema o This type of emphysema involves distal part of the acinus, while proximal part is normal.This type of emphysema is a common cause of spontaneous pneumothorax in young adults 4) Irregular emphysema (Para-cicatricial emphysema) o The acinus is involved irregularly and is almost invariably associated with scarring. It is the most common type of emphysema histologically Remember o Most common type of emphysema is irregular emphysema, but it is not clinically significant as most patients are asymptomatic and it is only an autopsy finding. Most common type of emphysema seen clinically is centracinar emphysema. | Pathology | Obstructive Lung Diseases |

90d55422-6805-4138-8797-a067a745729b | A 54-year-old man is brought to the emergency after experiencing several syncopal episodes. The patient states that he is currently taking erythromycin for treatment of bronchitis and another medication for treatment of gastroesophageal reflux disease (GERD). If an electrocardiogram reveals torsades de pointes, the patient is most likely taking which of the following medications for treatment of his reflux disease? | Cisapride | Famotidine | Lansoprazole | Metoclopramide | 0a
| single | This question is about an impoant drug interaction occurring between erythromycin and cisapride (used for gastroesophageal reflux disease- GERD). Serious cardiac arrhythmias, including torsades de pointes, QT interval prolongation, ventricular tachycardia, and ventricular fibrillation, have been repoed in patients taking cisapride with medications that inhibit cytochrome P450 3A4. Examples of medications other than cisapride that have a similar interaction with erythromycin include ketoconazole, fluconazole, clarithromycin, nefazodone, and indinavir. It is impoant to note that QT prolongation, torsades de pointes, cardiac arrest, and sudden death have occurred in patients taking only cisapride. None of the other agents listed interact with erythromycin to produce these proarrhythmic effects. Famotidine is an H2 receptor antagonist used in the treatment of GERD and gastric ulcers; this agent is generally well tolerated with very little incidence of drug interactions. Lansoprazole is a proton pump inhibitor indicated for the treatment of gastric ulcerations and GERD. When this agent is administered with phenytoin, the clearance of phenytoin is decreased by 15%, leading to an extension of the therapeutic effect. Metoclopramide is a prokinetic agent indicated for the treatment of GERD and diabetic gastroparesis. When given with cyclosporine, the toxic effects of cyclosporine are more pronounced. Fuhermore, when metoclopramide is administered with levodopa, it decreases the effectiveness of levodopa. | Pharmacology | null |

| multi | Trochlear nerve is thinnest nerve. It is the only nerve to emerge from dorsum of brain stem has longest intracranial course. It enters orbit through outer part of superior orbital fissure (ie lateral to annulus of Zinn) and supplies superior oblique muscle. Because it's a crossed cranial nerve (with decussation in mid brain), the trochlear nerve nucleus supplied contralateral superior oblique muscle. | Anatomy | null |

313427b1-7ec6-437b-9fd4-b4cc5a70972a | An old lady was brought to the ER in an unconscious state. She has a history of previous such attacks in the past months. An ECG was done and the graph obtained is given below. Which of the following is most probable cause? | PSVT | Atrial flutter | Ventricular bigeminy | 2 :1 block | 3d
| single | Ans. D. 2:1 blockElectrocardiography and Electrophysiology of AV conduction blockAV conduction block typically is diagnosed electrocardiographically, which characterizes the severity of the conduction disturbances and allows one to draw inferences about the location of the block. AV conduction block manifests as slow conduction in its mildest forms and failure to conduct, either intermittent of persistently, in more severe varieties.a. First degree AV block (PR interval >200ms) is a slowing of conduction through the AV junction. The site of delay is typically in the AV node but may be in the atria, bundle of his, or his Purkinje system. A wide QRS is suggestive of delay in the AV node proper or less commonly in the bundle of His. In second degree AV block there is an intermittent failure of electrical impulse conduction from atrium to ventricle.b. Second degree AV block is sub classified as Mobitz type I (Wenckebach) or Mobitz type II. The periodic failure of conduction in Mobitz, type I block is characterized by a progressively lengthening PR interval, shortening of the RR interval, and a pause that is less than the two times the immediately preceding RR interval on the electrocardiogram (ECG). The ECG complex after the pause exhibits a shorter PR interval than that immediately preceding the pause. This ECG pattern most often arises because of decremental conduction of electrical impulses in the AV node. | Medicine | C.V.S. |

| single | Coisol can stimulate mineralocoicoid receptors. But renal inactivation of coisol occurs to form coisone and thereby BP remains normal. SAME (Syndrome of Apparent Mineralocoicoid Excess) leads to lack of this inactivation. The resultant increase in coisol leads to excess activation of mineralocoicoid receptor and results in hypeension. | Medicine | Disorders of Adrenal Gland |

The ischemic muscles, when stretched, give rise to pain. Passive extension of fingers (streching the fingers) produce pain in flexor compament of forearm. Other features are Pulselessness, paralysis, Pallor and pain out of propoion to physical findings. Peripheral pulses, are present initially and disappear later. Therefore, pulse is not a reliable indicator for compament syndrome. | Surgery | null |

2ca21986-5f8c-4ba9-93ce-bf2b8df85882 | A 6 year old female patient complains of pain due to a decayed lower right 2nd molar. She has a history of unpleasant dental extraction with the lower left second molar. On seeing the dentist, the child immediately cries and withdraws. Which theory of child psychology best explains the reaction of the patient? | Operant conditioning by Skinner (1938) | Classical conditioning by Pavlov (1972) | Classical conditioning by Pavlov (1927) | Operant conditioning by Skinner (1952) | 2c
| single | Classical conditioning (1927) occurs readily with young children and can have a considerable impact on a young child's behavior on the first visit to a dental office. By the time a child is brought for the first visit to a dentist, even if that visit is at an early age, it is highly likely that he or she will have had many experiences with pediatricians and medical personnel. When a child experiences pain, the reflex reaction is crying and withdrawal. In Pavlovian terms, the infliction of pain is an unconditioned stimulus, but a number of aspects of the setting in which the pain occurs can come to be associated with this unconditioned stimulus. For instance, it is unusual for a child to encounter people who are dressed entirely in white uniforms or long white coats. If the unconditioned stimulus of painful treatment comes to be associated with the conditioned stimulus of white coats, a child may cry and withdraw immediately at the first sight of a white-coated dentist or dental assistant. In this case, the child has learned to associate the conditioned stimulus of pain and the unconditioned stimulus of a white-coated adult, and the mere sight of the white coat is enough to produce the reflex behavior initially associated with pain
Note: A) Acquisition – learning a new experience (fear of dentist/whitecoat/needles)
B) Generalization – generalizing all similar stimuli (all those wearing white coat cause pain)
C) Discrimination – differentiating individual stimuli ( not everyone who wears white coat causes pain)
D) Extinction - disappearance of the acquired experience ( loss of fear of dental procedures)
E) Spontaneous recovery – reappearance of extinct response ( fear of dental procedure reappears due to poor management behaviour strategies). | Dental | null |
