Malaria often causes severe disease, including high fevers, shivering chills, and flu-like symptoms. Humans are infected by Plasmodium falciparum, P. vivax, P. ovale, and P. malariae, four different types of malaria parasites. Additionally, P. knowlesi, a kind of malaria that infects macaques naturally in Southeast Asia, infects people as well, resulting in malaria that is transferred from animal to human ("zoonotic" malaria). The kind of malaria known as P. falciparum is the most likely to cause severe infections and, if untreated, may be fatal.

a situation whereby the demands of the situation exceed the resources and coping capacity of the family; occurs when the family is not able to cope with an event and becomes disorganized or dysfunctional
When a family is faced with a situation that exceeds their resources and coping capacity, it can lead to dysfunction and disorganization.
Resources refer to the tangible and intangible assets that a family has at their disposal to deal with stressors, such as financial means, social support, and problem-solving skills. Coping capacity refers to a family's ability to effectively manage stress and bounce back from adversity. If a family lacks adequate resources and coping capacity, they may struggle to adapt to the demands of the situation and may become dysfunctional. This can manifest in a variety of ways, such as increased conflict, communication breakdowns, and emotional distress. It is important for families to be aware of their resources and coping capacity and to seek out additional support if necessary to prevent dysfunction and promote resilience.

This can happen when external pressures, such as financial stress or health issues, surpass the family's available resources, both material and emotional, and their ability to manage the situation. As a result, the family may become dysfunctional, leading to a breakdown in communication, strained relationships, and an inability to effectively address the problem at hand. In order to overcome this situation, the family may need to seek external support, develop new coping strategies, or work on improving communication and problem-solving skills.

How much Dextrose 70% must be mixed with Dextrose 5% to prepare 1,000mL of Dextrose 20%? *
Answer:
231 ml
Explanation:
Let x represent the amo unt of Dextrose 70% in ml and y represent the amount of Dextrose 5% in ml needed to prepare 1,000mL of Dextrose 20%.
Since 1000 ml of Dextrose 20% is needed, hence:
x + y = 1000 (1)
Also 70% Dextrose is mixed with 5% dextrose to produce 20% dextrose. i.e.:
70% of x + 5% of y = 20% of 1000
0.7x + 0.05y = 200 (2)
We have to solve equations 1 and 2 simultaneously.
Let us multiply equation 2 by 20:
14x + y = 4000 (3)
subtract equation 1 from 3:
13x = 3000
x = 231 ml
Put x = 231 in equation 1 to find y:
231 + y = 1000
y = 769 ml
Therefore 231 ml of Dextrose 70% must be mixed with 769 ml of Dextrose 5% to prepare 1,000mL of Dextrose 20%? *
