What type of cell does the Giemsa stain? - White blood cells What type of samples are acid-fast stains often performed on? - Sputum samples (thick mucus produced in lungs that can be coughed up) The naked eye can see up to ______ micrometers. - 100 micrometers Cellular organelles can be as small as ______ micrometers. - 0.2 micrometers Does phase contrast need staining? - No What is the difference between phase contrast compared to brightfield? - You are able to visualize things t...

What is the total magnification on (relative to your eye) of a sample imaged with a 60x objective and a 10x eyepiece? Show your math. - 60x objective x 10x ocular = 600x magnification True or False: Staining is often required to image a cell that is adherent and flat (thin). - True Adherent, flat and unstained cells are almost invisible due to the limits on both resolution and contrast. Therefore, cell staining is often required to adequately image the sample. True or False: A cell th...

The incident commander - the general briefing is critical to creating a common operational picture of the incident. This briefing is usually conducted by drive changes in training, equipment, material - A thorough critique or After Action Review is a critical component of all aspects of emergency response. A critique may help managers In Service - Resources at an incident will be one of the following Last Known Point (LKP) - is defined as the last place the subject is verifiably known t...

What is believing in a Recoverees capacity for producing a desired result? - Supporting Self Efficacy The way we ask good questions is by: - Motivational Interviewing Which stage of change describes the Recoveree actively making changes to target behavior? - Action What is defined as the depth and breadth of internal and external resources that can be drawn upon to initiate and sustain recovery? - Recovery Capital What do we call the document to help Recoverees set goals in the CCAR ...

What is the relationship between pathogen load and the severity of symptoms? A) Higher pathogen load typically correlates with more severe symptoms B) A high pathogen load usually results in no symptoms C) Pathogen load has no effect on symptom severity D) A low pathogen load causes severe symptoms - A) Higher pathogen load typically correlates with more severe symptoms Which stage of infection involves the host repairing tissue damage and returning to normal health? A) Incubation period...

Crohn's disease S&S - abd pain, diarrhea, dehydration, bloody stools, malabsorption, malnutrition, weight loss, intestinal obstruction from chronic inflammation, fistulas and perforation of the intestine Diverticular disease - Characterized as the presence of diverticula in the large intestine. Risk factors include older age, genetic predisposition, obesity, smoking, diet, lack of exercise, ASA and other NSAIDS, altered DI microbiome and abnormal colonic peristalsis Diverticulosis/Diver...

Myxedema coma - thyroid emergency which has the opposite effect of thyroid storm. Results in decreased LOC and is usually precipitated by an event such as infection, discontinuation of thyroid medications, narcotic or sedative use. other S&S hypotension, hypoventilation, shivering, hypothermia, lactic acidosis, coma, and hypoglycemia. Type 1 DM - 3 types: 1A is autoimmune, 1B is idiopathic and 3c is associated with chronic pancreatitis. in 1A: autoimmune response destroys the beta cells in th...

Metaplasia examples - Most common is change from columnar cells to squamous cells (chronic smokers). Less common is change from squamous to columnar cells, like in Barrett Esophagus caused by heart burn. Carcinoma in situ - Pre-invasive epithelial malignant tumors of glandular or squamous origin. Sites including cervix, skin, oral cavity, esophagus, and bronchus Hypoxic injury - 1. Decrease in oxygen in the air (high altitudes, asphyxiation, drowning) 2. Loss of hemoglobin function (hem...

What is the primary characteristic of shock? A) Hypertension B) Inadequate tissue perfusion C) Increased oxygen delivery D) Increased cardiac output - B) Inadequate tissue perfusion Rationale: Shock is defined by inadequate tissue perfusion, leading to decreased oxygen and nutrient delivery to cells. Which of the following best describes the primary consequence of anaerobic metabolism in shock? A) Increased ATP production B) Increased oxygen consumption C) Lactic acid accumulation ...
