The following are assessment finding for a client with pre-eclampsia: blood pressure 158/100; urinary output 50 mL/hour; lungs c
Neko [114]

1)Blood pressure 158/104

2)urinary output 20ml per hour

3)Reflexes 21

4)Platelet count 150,000

Answer: The correct answer is (2) urinary output 20ml per hour

Explanation:

Preeclampsia is a condition in pregnant women, or could develop after delievry, where her blood pressure rises significantly, >140/90 mmHg(recorded on two occasions,atleast 4 hours apart).Moreover urine test indicates protein in her urine(proteinuria), swelling particularly of hands,legs and feet(edema),severe headaches along with many other symtoms.

On the next hourly assessment,

• The client's BP was recorded as 158/104, which is almost the same as it was initially recorded,i.e 158/100, which means her BP did not rise significantly.

•The client's reflexes are normal

•The client's platelet count is normal too, although it is on a lower side(normal range is between 150,000-450,000)

•Decrease in urinary output(20ml/hr) is an indication of worsening of preeclampsia because this indicates there is decreased renal perfusion which may subsequently lead to decreased GFR(glomerular filtration rate).

How do you define newtons first law
Leokris [45]

ANSWER:

THE THREE LAW OF MOTIONS ARE LAW OF INERTIA, LAW OF INTERACTION & LAWW OF MASS AND ACCELERATION

  • Law of Inertia - An object at rest and an object in motion stays in motion with the same speed and in the same direction.
  • Law of Interaction - For every action, there is an equal but opposite reaction.
  • Law of Mass and Acceleration - The acceleration of an object as produced by a net force is directly to the magnitude of the net force and inversely propotional to the mass of the object.

<em>F= ma ;  a=F/m</em>

<em />

wherein;

<em>F= Force (N)</em>

<em>m= mass (kg)</em>

<em>a= acceleration (m/s^2)</em>
