A med-surg patient is scheduled to receive docusate (Colace) at 9am. The night nurse advises the patient had two loose stools during her shift. The nurse would anticipate:
Administering half of the scheduled dose of Colace
Administering the scheduled dose of Colace
Inserting a rectal tube to prevent excoriation
Holding the scheduled dose of Colace and notifying the ordering physician
The Correct Answer is D
Choice A reason: Administering half of the scheduled dose of Colace is not the correct action for the nurse who is caring for a patient who had two loose stools during the night shift. Colace is the brand name of docusate, which is a stool softener that works by increasing the amount of water and fat in the stool, making it easier to pass. Colace is used to treat and prevent constipation, which is a condition of infrequent or hard bowel movements. Colace is not indicated for diarrhea, which is a condition of frequent and loose bowel movements. Administering half of the scheduled dose of Colace may not be enough to prevent constipation, and it may also worsen diarrhea by adding more water and fat to the stool.
Choice B reason: Administering the scheduled dose of Colace is not the correct action for the nurse who is caring for a patient who had two loose stools during the night shift. Colace is the brand name of docusate, which is a stool softener that works by increasing the amount of water and fat in the stool, making it easier to pass. Colace is used to treat and prevent constipation, which is a condition of infrequent or hard bowel movements. Colace is not indicated for diarrhea, which is a condition of frequent and loose bowel movements. Administering the scheduled dose of Colace may not be necessary to prevent constipation, and it may also worsen diarrhea by adding more water and fat to the stool.
Choice C reason: Inserting a rectal tube to prevent excoriation is not the correct action for the nurse who is caring for a patient who had two loose stools during the night shift. A rectal tube is a device that is inserted into the rectum and connected to a drainage bag, which collects the stool and prevents leakage and skin irritation. A rectal tube is used for patients who have fecal incontinence, which is the inability to control bowel movements. A rectal tube is not indicated for patients who have diarrhea, which is a condition of frequent and loose bowel movements. Inserting a rectal tube may not be effective to prevent excoriation, and it may also cause complications such as infection, bleeding, or perforation.
Choice D reason: Holding the scheduled dose of Colace and notifying the ordering physician is the correct action for the nurse who is caring for a patient who had two loose stools during the night shift. Colace is the brand name of docusate, which is a stool softener that works by increasing the amount of water and fat in the stool, making it easier to pass. Colace is used to treat and prevent constipation, which is a condition of infrequent or hard bowel movements. Colace is not indicated for diarrhea, which is a condition of frequent and loose bowel movements. Holding the scheduled dose of Colace may be appropriate to avoid further diarrhea, and notifying the ordering physician may be necessary to determine the cause and the treatment of diarrhea

Correct Answer is A
Explanation
Choice A reason: This is correct. The kidneys are the main organs for excreting water-soluble substances, including most drugs and their metabolites. The kidneys filter the blood and remove waste products and excess fluid as urine. Drugs can be excreted by glomerular filtration, tubular secretion, or tubular reabsorption.
Choice B reason: This is incorrect. The pancreas is not involved in excretion of drugs. The pancreas is an organ that produces digestive enzymes and hormones, such as insulin and glucagon.
Choice C reason: This is incorrect. The gallbladder is not involved in excretion of drugs. The gallbladder is an organ that stores and concentrates bile, a fluid that helps digest fats.
Choice D reason: This is incorrect. The liver is not primarily responsible for excretion of drugs, although it plays an important role in drug metabolism. The liver is an organ that performs many functions, such as detoxifying substances, synthesizing proteins, and producing bile. The liver can transform drugs into more polar and water-soluble compounds, which can then be excreted by the kidneys or the biliary system.
Correct Answer is B
Explanation
Choice A reason: 3% sodium chloride is a hypertonic solution that can cause fluid shifts and dehydration. It is not a suitable replacement for TPN, which is also hypertonic but provides calories, electrolytes, vitamins, and minerals. Infusing 3% sodium chloride can lead to hypernatremia, increased intracranial pressure, and cellular damage.
Choice B reason: Dextrose 10% in water is a hypertonic solution that can provide some calories and prevent hypoglycemia. It is the best option among the choices to replace TPN temporarily, until the new container arrives. However, it does not provide adequate nutrition or electrolytes, so it should not be used for a long time.
Choice C reason: Lactated Ringer's is an isotonic solution that can maintain fluid balance and electrolytes. It is not a suitable replacement for TPN, which is hypertonic and provides more calories and nutrients. Infusing Lactated Ringer's can lead to fluid overload, hyponatremia, and metabolic alkalosis.
Choice D reason: 0.9% sodium chloride is an isotonic solution that can maintain fluid balance and sodium levels. It is not a suitable replacement for TPN, which is hypertonic and provides more calories and nutrients. Infusing 0.9% sodium chloride can lead to fluid overload, hyponatremia, and metabolic acidosis.
