"1. A closer look - Food insecurity in the United States
According to the United Nations Food and Agriculture Organization, approximately 795 million people are chronically undernourished worldwide. Undernutrition means that a person consumes insufficient energy to meet his or her metabolic needs. Many food security organizations set this minimum at 2,000 kcal/day for a person to be well nourished.
Examine the figure depicting the food security status of U.S. households and then answer the question that follows.
1. According to the definitions used by the USDA Economic Resource Service, what percentage of U.S. households had access, at all times, to enough food for an active, healthy life for all members?
86%
5.6%

2. According to the U.S. Department of Agriculture, a rib eye steak has an energy density of approximately 2,650 kcal/kg. A person could conceivably consume 730,000 kcal/year simply by eating 275.5 kg of steak over the course of a year, or 26.5 oz every day. Would a person who did this be likely to be properly nourished, and why or why not?
No; 730,000 kcal/year is not enough food to avoid undernutrition.
No; beef is too fattening. The person would probably suffer from overnutrition.
Yes; 730,000 kcal/year is a reasonable minimum level of consumption to avoid undernutrition.
No; beef lacks some essential nutrients. The person would probably suffer from malnutrition.

what is the amount of medication left after one half life?
Understanding the concept of half-life is useful for determining excretion rates as well as steady-state concentrations for any specific drug. Different drugs have different half-lives; however, they all follow this rule: after one half-life has passed, 50% of the initial drug amount is removed from the body.As with previous half-lives, this indicates that elimination is 50% complete after one elimination half-life, 75% complete after two elimination half-lives, and about 99% complete after seven elimination half-lives.The half-life of a drug is the time it takes for the amount of a drug's active substance in your body to reduce by half.

Increased production of lactic acid is the physiologic change related to acute compartment syndrome is responsible for symptoms of flexed posture and unequal pulses in a patient.
What is the cause of the flexed posture and unequal pulses in a patient with acute compartment syndrome? Acute compartment syndrome occurs when an increase in pressure within a confined space of the body (such as a muscle compartment) causes a decrease in blood flow and oxygen to the tissues. This can result in pain, swelling, and a decrease in sensation. The flexed posture is due to the pressure within the compartment, causing the muscles to contract and be in a flexed position. The unequal pulses are due to the decreased blood flow, which can cause a difference in the strength and rate of the pulses in the affected limb compared to the unaffected limb. In severe cases, irreversible damage to the nerves and muscles can occur if the pressure is not relieved quickly.

in a patient with toxicity due to the beta-blocker sotalol (betapace), which electrocardiogram findings should you expect to see? ena
In a patient experiencing toxicity owing to the beta-blocker sotalol (betapace), the ECG findings we could anticipate are "bradycardia and prolonged QT intervals". The correct answer is D.
There are many different beta-blockers, and each one of them has the potential to block sodium or potassium channels. As a result, the QRS interval and the QTc interval will be prolonged . There is a theory that beta-blockers that block sodium channels have something called "membrane stabilizing action," which can make an overdose more toxic.
Beta-blocker overdose may be indicated by hypotension-induced bradycardia. BB poisoning causes hypoglycemia and impaired mental state, unlike calcium channel blocker overdose. Beta-blocker overdose symptoms normally develop within one to two hours, although sotalol toxicity can last up to 20 hours.
