Medications for diarrhea that work by absorbing excess fluid in fecal matter in the colon without affecting transport processes across the membrane are known as?
Laxatives
Antimotility agents
Adsorbents
Bulk-forming agents
The Correct Answer is C
A. Laxatives are used to relieve constipation by promoting bowel movements, not for treating diarrhea.
B. Antimotility agents work by slowing down the movement of the intestines, which can reduce diarrhea, but they do not specifically absorb excess fluid in the fecal matter.
C. Adsorbents, such as activated charcoal or kaolin-pectin, work by absorbing excess fluid in the fecal matter in the colon, which helps to reduce diarrhea without affecting transport processes across the intestinal membranes.
D. Bulk-forming agents, like psyllium, absorb water and increase the bulk of stool, which is used for constipation rather than diarrhea.

Correct Answer is D
Explanation
A. Identifying specific pathogens is important for guiding treatment, but the immediate focus in septic shock is on supporting circulation and treating the source of infection rather than just identification.
B. Improving tissue perfusion through intravenous fluid and blood replacement is part of the treatment but is not the sole focus. It is a supportive measure, and it is done alongside treating the source of infection.
C. Administering antibiotics is critical in septic shock but is only part of the treatment. It should be done alongside efforts to support circulation and treat the source of infection.
D. Treating the source of infection and supporting circulation are the primary goals in managing septic shock. This includes administering fluids, antibiotics, and sometimes vasopressors, in addition to addressing the underlying infection.
Correct Answer is A
Explanation
A. Dehydration increases the risk of renal calculi (kidney stones) because it leads to concentrated urine, which promotes the formation of stones. When there is insufficient fluid intake, the kidneys cannot dilute substances like calcium and oxalate, which can form crystals and eventually stones.
B. A sedentary lifestyle is a risk factor for a variety of health issues, including obesity, but it does not directly increase the risk of kidney stones. Physical inactivity can contribute to weight gain, which in turn may increase the risk of developing stones, but it is not as direct a cause as dehydration.
C. Drinking 32 ounces of milk per day does not directly increase the risk for kidney stones. In fact, moderate calcium intake can help prevent the formation of certain types of kidney stones. However, excessive calcium intake from supplements (rather than food) may increase the risk.
D. Running 5 miles does not increase the risk of kidney stones. In fact, regular physical activity can help prevent the formation of kidney stones by promoting overall health and hydration.
