1. A 60-year-old man presents to his physician after a routine screening test indicates hyperlipidemia. Physical examination reveals raised, irregular, yellow papules in the skin of the soft tissues below the eyes. Biopsy of these lesions would most likely show which of the following?
A. Benign nevus cells
B. Malignant nevus cells
C. Microscopic blisters
D. Munro microabscesses
E. Multinucleated giant cells
2.A newborn baby is noted to have extremely pale skin, white hair, and red irises. A sibling has similar characteristics. The pediatrician instructs the family to be careful to avoid sun exposure in this child because of the markedly increased risk of developing cancer. Which of the following diseases has the highest incidence in these patients?
A. Basal cell carcinoma
B. Keratoacanthoma
C. Malignant melanoma
D. Paget disease
E. Squamous cell carcinoma
3.A 50-year-old man presents with shortness of breath. The patient has a history of cigarette smoking, but has been otherwise healthy. He is afebrile. On examination, he has absent breath sounds halfway up on the right side of the lung fields, with decreased resonance and tactile fremitus. A chest x-ray film shows that the trachea is deviated to the right. Which of the following is the most likely diagnosis?
A. Bronchial obstruction
B. Pleural effusion
C. Pneumococcal pneumonia
D. Pneumothorax
E. Viral pneumonia
I dont know answers for these questions bcas i've found these questions in a quiz and anwers are not given.
Give them a shot and tell the correct answers.

@nnl
I agree with answer for 1st question.
2.If baby is suffering from Albinism,according to kaplan notes,there is an increased risk of developing basal cell and squamous cell carcinomas.According to USMLEWORLD,there is an increased risk of developing skin cancers of all types.
Sun exposure is a risk factor for basal cell carcinoma,squamous cell carcinoma,and malignant melanoma.
Can you please explain your reason for picking squamous cell carcinoma?
3.Bronchial obstruction with a mucus plug,tumor,or a foreign body can lead to atelactasis.
Fever is an important in diagnosing atelactasis,but question says that patient is afebrile.And atelactasis clinically causes signs of consolidation which includes increased tactile fremitus,but the question again says that there is decreased tactile fremitus in the patient.
Is there something in the question iam missing?

My answers were:
1.Multinucleated giant cells
2.Squamous cell carcinoma....i dont know the reason but i just picked that choice....out of 3 skin cancers i picked this one by lottery
3.Pleural effusion.

About squamous cell i just choose Squamous cell and i didnt look it up yet but i had read somewhere that there was a co-relation and so choose havent looked it up yet.
I choose bronchial obstruction cos Decreased breath sounds and tactile fremitus with TRACHEA SHIFTED TO THE AFFECTED is the biggest clue to Bronchial obstruction. I was going with pleural effusion first and then saw trachea shifted to right went back and re checked the affected side. and then choose Bronchial obstruction. Cos both have the same dec sounds and percussion and tactile fremitus while the only difference is that trachea shift decides whether its effusion or obstruction. Only in cases of resorption atelectasis would you see the opposite shift otherwise its same sided.

It took me a couple of classical patients and then our Prof asked us to look very closely at the trachea and we will see the shift. And then helps in making a faster diagnosis then reconfirm it with a CXR but you have an idea of whats going on.
