Karen is asked to look at two spots of light and judge which one gets brighter over time. Both spots start out at 100 units of brightness. She notices that the right spot is brighter when it is 110 units. If she is presented with two new spots of light both starting at 300 units, how much brighter will one have to get before she will be able to reliably detect the difference?.

Answers

Answer 1

One spot has to get 30 units brighter before she will be able to reliably detect the difference.

Karen is asked to assess which of the two light sources gets brighter over time. The initial brightness of both spots is 100 units. When it is 110 units, she observes that the right spot is brighter. If she is given two fresh light spots, each beginning at 300 units. She won't be able to distinguish between the two light spots until one of them becomes 330 units brighter than the other.

She became aware of the difference in the first bulb when the right one was 0.10 percent brighter than the other. The second scenario requires that one of the spots be 0.10% brighter than the other if we use the same logic.

300 ₓ 0.10 = 30 units

300 ₊ 30 = 330 units

Hence, the other spot should be at 330 units of brightness in order to distinguish it from the first one.

The nurse is preparing to administer a liquid form of medication to a client. what action will the nurse take to ensure that administration of the drug is at the desired potency?

Answers

The nurse is getting ready to give a patient a liquid medication. To ensure that the drug is administered at the desired potency, the nurse should check the expiration date.

Why should we check the expiration date on liquid medications?

Since liquid drugs have a tendency to become stronger or weaker over time, checking the expiration date on them can help ensure they are still at the proper potency. Giving a patient a drug that has expired could be harmful to them. Because many liquid drugs have an unpleasant odour, detecting an odour does not guarantee the potency of the prescription. A precaution to take to ensure safe administration is to return the drug if the label is unclear, however doing so has no bearing on the medication's potency.

What significance do medicine expiration dates have?

Antibiotic resistance can develop when ineffective medications are used to treat infections, leading to more severe illnesses. Certain medicines that have expired run the risk of developing germs. Once the expiration date has past, the medication's safety and efficacy cannot be guaranteed.

How important is the expiration date on a prescription?

Knowing when to take your meds might help you organize your regimen. After their expiration date, medications may no longer be as safe or as effective. It is not advisable to consume medication that has expired.

Scientists mixed local bees with African ones to create a bee that would make more honey. They ended up with something much different. The new bees evolved in unexpected ways. They multiplied and migrated north. Africanized honey bees are now known as killer bees for several scary but legitimate reasons.Killer bees are far more aggressive than their relatives. They have been known to attack in great numbers, even when there has been no direct threat on their hives. They have swarmed because of loud noises, dark clothing, bright jewelry, and even strong perfume. They will chase a person for more than a quarter of a mile and remain angered for up to 24 hours.Killer bees are also dangerous because of their sting. While most bees take up to 30 seconds to attack, killer bees sting in just 3 seconds. Their venom is no stronger than a regular bee's, but when one killer bee stings, others follow. With up to 80,000 members in a colony, victims are quickly overwhelmed. So many stings in such a short time can cause allergic reactions. Victims enter a state of shock, lose blood pressure, and in many cases, die.A final reason why "killer" has been added to their name is the unfortunate number of deaths they have caused. Experts estimate that the Africanized honeybee moves at a rate of about 200 miles each year. As the bees claim new territory, they claim new victims as well. More than 1000 people have been stung to death in South and Central America. There have been rising numbers of attacks in Mexico and a handful in the United States. Once a swarm sets sights on a victim, it is very difficult for the victim to escape. Once attacked, it is very difficult to survive.Thankfully, there has been no killer bee invasion as some once predicted. Although there is no need for panic, the threat of the killer bee is real and should be taken seriously. It is good practice to call a professional to remove beehives in your area. If you are stung multiple times by any insect, you should always seek medical attention. You may not be expert enough to tell the difference between a killer bee and a less dangerous one, so be smart.
