What does the clock-drawing test indicate?
The clock-drawing test is able to detect mental decline as people with dementia often have problems reading traditional clocks. Reading clocks requires you to interpret the placement of the hands on a clock and the time they are meant to represent. This ability is often lost in people with early dementia.

Where to find pulse?
The pulse can be found on the side of the neck, on the inside of the elbow, or at the wrist.
What does pulse mean in medical terms?
The pulse rate is a measurement of the heart rate, or the number of times the heart beats per minute. As the heart pushes blood through the arteries, the arteries expand and contract with the flow of the blood. Taking a pulse not only measures the heart rate, but also can indicate the following: Heart rhythm.

What are the two mnemonics that work well together?
They pulled all these ideas together and wrapped mnemonics around them to make them easier to remember. Two mnemonics that work well together are HEIDI and TIME. These stand for History, Examination, Investigation, Diagnosis and Implementation (HEIDI) and Tissue, Inflammation, Moisture and Edges (TIME). To help remember these I have included a data collection tool you can use, see Appendix A. Now we will go into ALOT more detail about each of these.
Why is the collection of information important in the digital age?
Collection of information in the digital age has allowed us to access the data easier, to quickly determine trends in healing , or to use the information for research (for example, assessing indicators of potential venus leg ulcer recurrence (51) ). The internet provides us with a wealth of wound management information, some excellent (Wounds International, World Wide Wounds) and some which are, well let’s say, not peer reviewed… Within our healthcare settings the majority of our WATs are still paper-based and we continue to measure with disposable rulers. However, the digital age is encroaching on wound care.
What is autolytic dressing?
Autolytic. Uses the body’s own enzymes and moisture to rehydrate, soften and liquefy hard eschar and slough using occlusive or semi-occlusive dressings and/or antimicrobial products to create a balanced moist wound environment either by donating or absorbing moisture.
What do edges give us?
Also, the edges can give us information to help diagnose the type of wound. Below is a table showing edge characteristics and their likely correlations to wound type. However, this is just a guide and not a diagnosis by itself.
Do not allow for the migration of keratinocytes across the wound bed?
do not allow for the migration of keratinocytes across the wound bed. Addressing the underlying cause should be the answer, but debridement or the use of adjunctive therapies may need to be considered. The aim is to encourage keratinocyte migration and wound contraction; this will be seen as an advancing wound edge and reduction in wound bed size (6). The edges really are the final indicator to let you know that everything else you did with T, I, and M is working or not.
Why is clock used in sequential systems?
So, we try to synchronize the working of all the subsystems in a sequential system by using a clock. Therefore, clock is used to bring some regularity to the system. So, a clock signal is a particular type of signal that oscillates between a high and a low state and it is used to coordinate actions of digital circuits.
What is the duty cycle of a clock?
Clock has fixed time period and generally in most applications duty cycle is 50% i.e. for half of the time period its value is high and for other half it is low.
What is the physical design of a flip flop?
Now lets examine why there should be such a requirement. The physical design of the flip flop will consists of CMOS . Each of these transistors will have certain capacitance associated with it and as you know, capacitance introduces delay in circuit so basically from the time of applying the signal to receiving it at other end there will be a delay. Further circuits (internal/external) connected to the output and input introduces more capacitance. So there will be some delay in the logic, this is usually quanitified in terms of setup time
What is a clock waveform?
Clock is a square waveform switching from high to low indefinitely at fixed intervals often employed in digital electronic circuits to synchronize the function of each circuit element.
How to divide a reference frequency to a far lower frequency?
So you can take a reference frequency that is highly accurate (say 10s of MHz) and divide it down to a far lower frequency by cascading additional flip-flops, each ÷2 and the cascade being a power of two: ÷2, ÷4, ÷8, ÷16, etc., down to 1 Hz which is 1 pulse per second. Obviously the original frequency must be a power of 2 in this case.
What is the state of logic in a sequential circuit?
The state of Logic from the memory element (clock) with the relevant present state input (Set and Reset combination) forms a present state output in the sequential circuit.
