Signs of Infection  • Fever  • Lethargy  • Slow-wave sleep induction  • Classic signs of inflammation (redness, swelling, heat, and pain) Types of Antibiotics  • Bacteriostatic  • Bactericidal Bacteriostatic  - Those substances that prevent the growth of bacteria Bactericidal  - Those that kill bacteria directly Bacteria Classification  • Gram-positive  -The cell wall retains a stain or resists decolorization with alcohol  • Gram-n...

a nurse is admitting a client who has a suspected MI and a history of angina. which of the following findings will help the nurse distinguish stable angina from an MI? a. stable angina can be relieved with rest and nitroglycerin b. the main of an MI resolves in less than 15 minutes c. the type of activity that causes an MI can be identified d. stable angina can occur for longer than 30 minutes  a a nurse on a cardiac unit is reviewing the lab findings of a client who has a dx of MI an...

A culture is obtained when a patient has a bladder infection for the purpose of  growing and identifying causative organisms The sensitivity part of a culture and sensitivity test is for the purpose of  testing anti-infective medications to see which ones are most effective against the causative organism Tests for typhoid are considered _______ test (what type of test)  serology When taking a culture sample from an infected throat, the nurse should  don sterile gloves and ob...

Interphase  cell feeds, metabolizes and grows while replicating DNA in preparation for mitosis Prophase  first appearance of chromosomes (will be 92) Metaphase  Centrioles pull chromosomes to opposite sides of cell (chromatid) - 46 each side Anaphase  Centromeres split and sister chromatids are pulled apart Telophase  New nuclear membrane formed around each group of 46 chromosomes *When it goes right, euploid cells are produced* ~ 1 ~ for inquiry mail me @ Best G...

properties of the action potential  rising phase  overshoot  falling phase  undershoot What happens when the current reaches threshold?  generate APs at a low rate What happens when current increase?  rate of AP generation increases increases the frequency of AP (all or none situation) What does the firing frequency of APs reflect?  the magnitude of the DEPOLARIZING current (since hyperpolarizing would not allow threshold to be reached) ~ 1 ~ for inquiry mail ...

| Correct Answers | 2024/ 2025 What occurs during lissencephaly  The ventricles are dramatically enlarged Subcortical white matter is nearly absent Sulci and gyri are completely absent Children ten to have very small heads What are the two forces displaced when ions moving across the membrane  1. Electrostatic forces: positive ions will always want to move to a negative solution 2. Diffusion: particles move down their concentration gradient (high to low concentration ) 3. Io...

lecture 6 - The first phase of human brain-imaging involved X-ray based methods, such as-----  pneumoencephalography pneumoencephalography - how does this work generally , what are the cons of this method  •Air is injected into subarachnoid space to improve X-ray contrast •Makes the ventricles more translucent than surrounding tissue - specifically the lateral ventricles - You can see the c shape of the lateral ventricles - Was useful for visualizing ventricular anomalies caus...

Action Potential  Dramatic redistribution of electrical charge across membrane. Rapid reversal of charge across membrane such that the interior becomes relatively positive (depolarization caused by influx of sodium) How to determine MP  Microelectrode in cell, voltmetre used to measure electrical potential between tip of intracellular and extracellular microelectrode Membrane potential at rest  ~-65mV Key parts of Action Potential  Rising phase, overshoot, falling phase,...
