Individuals eliminate alcohol from their bodies at an approximate rate of __________.
.018 BAL per hour
.08 BAL per hour
.015 BAL per hour
.05 BAL per hour
Individuals eliminate alcohol from their bodies at an approximate rate of .015 BAL per hour. Correct answer: C Once alcohol has entered your bloodstream, your body will begin to metabolize it at a rate of 20 milligrams per deciliter (mg/dL) per hour. Despite the fact that alcohol is metabolized at a constant rate, some people may feel the effects of alcohol for longer amounts of time. The reason is because BAL is affected by several factors, like age, weight, medications...
A patient experiences chronic gastritis with a loss of parietal cells due to atrophy. the nurse determines that the patient is at risk for a complication associated with the loss of the parietal cells. which diagnostic test will assist in making this determination?
Answer: Biopsy (endoscopy)
Explanation: Chronic gastritis with a loss of parietal cells due to atrophy (i.e degeneration of cells) is usually caused by bacterial infection (often H. Pylori).
Parietal cells are epithelial cells that line the gastric and secretes hydrochloric acid (HCl) and intrinsic factor in the stomach.
The best approach to diagnose the presence or loss of parietal cells is through biopsy. It is carried out by insertion of an endoscope through the mouth and down into the stomach to pick stomach cells samples. Then, the abundance and stability of the parietal cells is observed.

A hypothesis that has been repeatedly disproved is that the MMR vaccine causes _____.
Which component of the ekg causes the heart to contract?
a. qrs complex
b. t wave
c. p wave
d. av node?
The QRS complex on the EKG is responsible for triggering the ventricular contractions, leading to the heart pumping blood.
Explanation:The component of the EKG that causes the heart to contract is the QRS complex. The QRS complex represents the depolarization of the ventricles, which is the signal that triggers the ventricles to contract and pump blood to the lungs and body. This process requires a much stronger electrical signal due to the larger size of the ventricular cardiac muscle. As the QRS complex reaches the peak of the R wave, the ventricles begin their contraction. The P wave, on the other hand, precedes ventricular contraction and represents the depolarization of the atria. Lastly, the T wave indicates ventricular repolarization, signaling the relaxation of the ventricles after they contract.
Final answer:
The QRS complex on an EKG triggers the contraction of the heart, specifically the ventricles, which is essential for pumping blood throughout the body. The correct option is a.
Explanation:
The component of the EKG that causes the heart to contract is the QRS complex. The P wave represents the depolarization of the atria and is followed shortly by the contraction of the atria. However, the actual contraction of the heart, specifically the ventricles which pump blood to the lungs and body, is triggered by the QRS complex. As the QRS complex reaches the peak of the R wave, the ventricles begin to contract. The T wave, in contrast, represents repolarization of the ventricles, which is the phase where the ventricles relax after contraction.
Hence, Option a is correct.

While auscultating breath sounds of a patient who was stung multiple times by a yellow jacket, you hear bilateral wheezing over all lung fields. this indicates:?
Bilateral wheezing indicates narrowing of the bronchioles, often due to inflammation as seen in asthma or allergic reactions. This can cause difficulty in breathing as the airway passages become constricted. Option D is correct .
This narrowing, also known as bronchoconstriction, occurs when the airways become inflamed and swollen, often accompanied by excessive mucus production. This constriction can be triggered by various factors such as allergic reactions, asthma, or environmental irritants.
Bilateral wheezing: This sound is generally due to the air trying to move through narrowed passages in both lungs.Narrowing of the bronchioles: This is common in conditions like asthma or allergic reactions, where the muscles around the airways tighten and the lining becomes inflamed and swells.Upper airway swelling typically presents with stridor, not bilateral wheezing. Lastly, enlargement of the bronchioles would not cause the kind of airway turbulence that leads to wheezing.
Complete question :
While auscultating breath sounds of a patient who was multiple times by a yellow jacket, you hear bilateral wheezing over all lung fields. This indicates: Select one:
A. a significant amount of fluid in the alveoli.
B. rapid swelling of the upper airway tissues.
C. enlargement of the bronchioles in the lungs.

Reduced fat means a food has 50% fewer calories than its normal counterpart
True or false?
The statement is false, reduced fat only means ".5-3 grams or 25% less fat than regular".
Typical foods produce 9 cal/g for their fat content and 4 cal/g for their protein and carbohydrate content. if a typical apple weighs 225 g and is 84% water, 14% carbohydrate, and 0.5% fat, how many calories of food energy does an apple provide?
Answer:
An apple provides a total of 136.125 calories.Explanation:
We know that
An apple weighs 225 grams, it has 84% water, 14% carbohydrate and 0.5% fat. Also, typical foods produce 9 calories per gram for their fat content and 4 calories per gram for their protein and carbohydrate content.So, to find the answer, we need to know the number of grams that is fat and carbohydrate.
Using the given percentages, we have
Fat: [tex](0.5\%)(225g)=0.005(225g)=1.125g[/tex]
Carbohydrate: [tex](14\%)(225g)=0.14(225g)=31.5g[/tex]
An apple has 1.125 grams of fat and 31.5 grams of carbohydrates.
If there are 9 calories per gram of fat, the total number of calories in this case would be
Fat: [tex]1.125g(9\frac{cal}{g})= 10.125cal[/tex]
If there are 4 calories per gram of carbohydrate, the total number is
Carbohydrate: [tex]31.5g(4\frac{cal}{g})= 126cal[/tex]
Therefore, an apple provides 10.125 calories from fat and 126 calories from carbohydrates, for a total of 136.125 calories.
Final answer:
To calculate the calories of food energy provided by an apple, we need to consider its macronutrient composition. By multiplying the weight of each macronutrient by its corresponding caloric content, we can determine the calories provided by the apple. In this case, an apple weighing 225 grams and having 84% water, 14% carbohydrate, and 0.5% fat provides approximately 136.125 calories of food energy.
Explanation:
To calculate the calories of food energy provided by an apple, we need to multiply the weight of each macronutrient by its corresponding caloric content and sum them up. Let's do the calculation:
Water content: 225 g x 0.84 (84%) = 189 g
Carbohydrate content: 225 g x 0.14 (14%) = 31.5 g
Fat content: 225 g x 0.005 (0.5%) = 1.125 g
Using the given caloric content, we can calculate the calories provided by each macronutrient:
Water: 189 g x 0 cal/g = 0 cal
Carbohydrate: 31.5 g x 4 cal/g = 126 cal
Fat: 1.125 g x 9 cal/g = 10.125 cal
Finally, we can sum up the calories from each macronutrient to obtain the total energy provided by the apple:
Total calories = 0 cal (water) + 126 cal (carbohydrate) + 10.125 cal (fat) = 136.125 calories
