respiratory system

1)The nurse administer oxygen at 5litre/min via nasal cannula to a client with emphysema. For which Clinical indicators should the nurse closely observe the patient ?

a) cyanosis and lethargy

Emphysema is a type of COPD. The abnormal presence of air in tissue or cavities of the body. In pulmonary emphysema distension of alveoli cause intervening walls are broken down and bullae to form on the lung surface and cause distension of the bronchioles and loss of elasticity. So inspired air can not be expired, making breathing difficult .

In emphysema cases unable to receive enough oxygen unless provided in a higher concentration on a long term basis. As stated above that nasal cannulas are used, they are capable of delivering 24% to 44% of oxygen at 1-6L/min

Administer oxygen for long term around 12 - 25 hours may cause hypercapnea that is carbon dioxide retention due to oxygen toxicity. This cause symptoms such as drowsiness ,decreased respiration, head ache and some times death.

5mm or more positive in

:HIV positive

:recent contact with active TB cases

:person with nodular and fibrotic changes in X-ray

:organ transplant recipient and immunosuppressed patient

10 my or more positive in

:recent arrival from high prevalence country

:IV drug abusers

:mycobacterial lab personal

:children less than 4 years of age

15mm or more

cardiovascular system

1)S2 heart sound corresponds to ____?

a) clossure  of aortic and pulmonary valve

b) closure of aortic valve

C) closure of the mitral and trivialise valve

d) closure of the mitral valve

Answer

Correct answer is option a, that is closure of aortic and pulmonary valve

Normal heart sound is S1 and S2. S1 is the first heart sound(LUBB)produced by closure of tricuspid and mitral valve and S2 sound is the second heart sound (DUBB) produced by closure of semilunar valve (aortic and pulmonic valve.

2)which of the following complication occur within 24 hours after sustaining an MI?

a) pulmonary embolism

b) heart failure

c) ventricular aneurysm

d) atrial septa defect

Answer

The correct answer is option c, that is ventricular aneurysm

Complications associated with MI is

:sudden death occurs with in fist hour

:ventricular aneurysm and ruptured papillary muscles with in 24 hours

:cardiogenic shock 24 hrs to 7 days

:cardiac rupture within 5-7days

:heart failure with in few days

:thromboembolism with in 3 weeks

Nervous system

1)if a nurse notice colorless drainage on dressing after surgery of brain tumor, then which of the following is the prompt nursing action?

a) notify the physician

b) elevate the head of the bed

c) documentation

d) monitor the patient continuously

2)Basic nursing measures in the care of patient with viral encephalitis

a) providing comfort measures

b) monitoring cardiac output

C) administer narcotic

d) administer amohotericin B

Answer

The correct answer is option a, providing comfort measures, it will directed to head ache ,include dimmed light, limited noise and analgesics are basic care for encephalitis .Other options are not a basic measures for viral encephalitis .

Endocrine system

1)short stature, secondary to growth hormone deficiency is associated with

a) height age is equal to bone age

b) normal body proportion

c) Low birth weight

d) normal epiphyseal developments

Answer

Correct answer is option b, normal body proportion

GHD babies born AGA not SGA

:they have maintained body proportion that is proportionate short stature.

:disproportionate SS is seen In

US is greater than LS___Richets and achondroplasia.

US is less than LS __spondylo epiphyseal displasia

GHD__delayed bone age but appropriated for height age

2)Glycated hemoglobin (HbA1c) test, mean glucose levels

a) over 2 days

b) over 15 days

c) over 90 days

d) over 30 days

Answer

The correct answer is option c, that is over 90days

HbA1c is test tells average levels of blood glucose over the past 3 months(90 days). It measures how much glucose is bound to RBC.

Renal system

1)amount of blood filtered in renal capsule per minute is known as ___

a) GFR

b) urine per minute

c) tidal volume

d) blood flow per minute

Answer

Correct answer is option a, GFR is used to test how well the kidneys are working. It estimate how much amount of blood passess through the glomeruli each minute. Normal GFR is 90 to 120 ml/min/1.73m²

2)triad symptoms in nephritis syndrome include all, EXCEPT

a) proteinuria

b) edema

c) weight loss

d) hypoalbuminemia

Answer

The correct answer is option c, weight loss

Nephrotic syndrome is defined by triad of clinical feature like edema, proteinuria and hypoalbumenemia. Weight gain is happened in nephrotic syndrome not weight loss.
