Examine the legs for color, capillary refill time, and tissue integrity when evaluating a client at risk for thrombosis.
Deep vein thrombosis is a condition when a blood clot (a thrombus) develops in a vein (DVT). This can dislodge and go into the bloodstream prior to reaching the lungs, where it can cause a pulmonary embolism (PE), a blockage in the pulmonary circulation that can be fatal.
In both primary and secondary care, nurses will be required to recognize and screen for deep vein thrombosis, therefore they must have the ability to evaluate the patient's clinical risk.
To utilize the Wells screening equipment properly, the leg must be extensively checked. Nurses ought to:
- Find any asymmetry or unilateral swelling, skin changes, wounds, oedema, erythema, or varicosities on both legs by keeping an eye out for them.
- Before palpating both legs, feel for heat with your hand over the suspected DVT location. Also feel for pain and any cracks in the skin.
- DVT symptoms can include deep venous system-specific pain.
- The difference in the calves' circumference is measured 10 cm below the tibial tuberosity.
- A DVT is the likely diagnosis if there is a discrepancy of more than 3 cm from the asymptomatic side.
- Check capillary refill time is between two and three seconds; this is a sign of peripheral perfusion by palpating the foot pulses.

Answer:
The answer is A promote an increase in blood pressure
Explanation:
Aldosterone is a mineralocorticoid hormone produced in the renal cortex and acts by retaining sodium and eliminating potassium which leads to an increase in blood pressure.
Answer:
The correct answer is D.
Explanation:
Bordetella pertussis is a gram-negative coccobacillus that causes a disease called whooping cough.
The bacterium infests the patients by colonizing lung epithelial cells. To do so, it requires adhesins, called filamentous haemagglutinin, fimbriae and pertactin. Once the bacterium is attached to the lung epithelial cells, it produces a cytotoxin that prevents their cilia from moving.
Another virulent factor from B. pertussis is the pertussis toxin, which alters host immune system through the inhibition of phagocytes response to it.
Since pathogens are easily passed from person to person, they need large populations to spread and survive. If they did not have a large population, the pathogens would die out.
