A nurse is planning care for a child who has severe diarrhea. which of the following actions is the nurse priority? A. Introduce a regular diet B. Rehydrate C. Maintain fluid therapy D. Assess fluid balance (Assess first the other three are interventions, before u intervene you have to assess how much fluid imbalance. Check for labs results because it will tell you what kind of fluid is to be given and how much fluid to be replaced. Priority is assessment first) A nurse is caring for a...

A nurse is teaching the mother of a child who has cystic fibrosis and has a prescription for pancreatic enzymes three times per day. Which of the following statements indicatesthat the mother understands the teaching? • “My child will take the enzymes to improve her metabolism.” • “My child will take the enzymes 2 hours before meals.” • “My child will take the enzymes following meals.” • “My child will take the enzymes to help digest the fat in foods.” 2. A nurse i...

Volkmann ischemic contracture d. Renal calculi 2. A nurse is teaching the parent of a toddler who has phenylketonuria about meal planning.

ecology “the study of the processes determining the distribution and abundance of organisms” (Krebs) or of “the interaction among organisms and between organisms and their environment” (Poulin) In infectious disease (ID) context: incidence (number of new infections per unit time) and prevalence (number of infected individuals in the population). We may also be interested in the parasite burden or intensity of infection: how many bugs/host on average? How do we get this information?...

Fungal disease has emerged as an increasing threat to a number of different organisms, especially amphibian species. Batrachochytrium dendrobatidis (Figure 1), a Chytridiomycota fungus that causes the infectious disease chytridiomycosis has been found to be the major cause of amphibian death caused by fungal infection. B. dendrobatidis infects the superficial, keratin-containing layers of amphibian skin.9 The infection then spreads across the skin, causing it to thicken and slough off. This thic...

Basics Group individuals into categories; figure out the rates at which various events (infection, recovery, death, etc.) occur, and how they move individuals between categories/change the population sizes; write down equations based on these rates. “All models are wrong but some are useful” (Tukey), but they can help us figure out the rate of spread, or the equilibrium prevalence. Some distinctions: micro- or macroparasite? Include vital dynamics (birth/death)? Life cycle (direct, vect...

Host populations So far we have been talking about the population dynamics of the pathogens themselves; now we’ll discuss how parasites affect the population dynamics of their hosts, whether wildlife (animal or plant) or human. Regulation Do parasites control population size? How? High infection rate, intermediate virulence (disease-induced death rate) have the greatest impact on a population (because virulence lowers by killing hosts “too quickly”). Can parasites regulate a populat...

Parasites can have large effects on their host populations and communities; can determine the competitive balance between two species, whether one species can invade or coexist with another; change the flow of energy through and relative balance of different trophic levels; act as “ecosystem engineers” to change the environment in which other organisms live; have cascading effects on entire ecosystems, determining their biomass or diversity. Indirect interactions Direct interactions a...
