A client's blood pressure drops from 120/76 to 90/60 mm Hg as soon as positive end-expiratory pressure (PEEP) is initiated for the treatment of hypoxemia. What is the most likely cause of this decrease in blood pressure?

Answers

Answer 1
Answer:

Answer:

Decrease in cardiac output

Explanation:

Blood pressure may be defined as the pressure exerts by the artery on the walls during the blood flow. The systolic pressure is used for the calculation of the blood pressure.

The blood pressure depends upon the cardiac output, heart beats and rate of the blood flow. The cardiac output is the volume of blood pumped in the body per minute. The decrease in the cardiac output will ultimately results in the decrease in the blood pressure.

Thus, the correct answer is decrease in cardiac output.

What percentage of alcohol is absorbed by the small intestine? 50-60%, 60-70%, 70-80%, 80-90%

Answers

Around 70-80% of alcohol is efficiently absorbed by the small intestine due to its big surface area. However, alcohol is also absorbed by all parts of the gastrointestinal tract. In fact, the stomach absorbs 10-20% of alcohol. This is the reason why people who have ingested food prior to drinking alcohol are able to hold their liquor better. Once the alcohol is absorbed, it travels throughout the body via the person's blood until equilibrium is achieved.

Final answer:

Approximately 90 percent of the water you ingest is absorbed by the small intestine.

Explanation:

The small intestine absorbs about 90 percent of the water you ingest. Water absorption is driven by the concentration gradient of the water, which is higher in chyme than in epithelial cells. Thus, water moves down its concentration gradient from the chyme into cells. The remaining water is then absorbed in the colon.
