Increased gastric motility and digestion are controlled by which of the following?
The parasympathetic nervous system
The limbic system
The central nervous system
The sympathetic nervous system
The Correct Answer is A
A) The parasympathetic nervous system:
This is the correct answer. The parasympathetic nervous system is responsible for regulating rest and digestion. It controls activities such as increased gastric motility, secretion of digestive enzymes, and relaxation of sphincters in the gastrointestinal tract. Activation of the parasympathetic nervous system promotes digestion and absorption of nutrients by increasing gastrointestinal activity.
B) The limbic system:
The limbic system is primarily involved in emotions, behavior, and long-term memory formation. While emotions can influence gastrointestinal function, including appetite and digestion, the limbic system itself does not directly control gastric motility and digestion.
C) The central nervous system:
The central nervous system includes the brain and spinal cord and plays a vital role in integrating and coordinating all body activities. While it indirectly influences gastrointestinal function through autonomic nervous system control, it is not the primary regulator of gastric motility and digestion.
D) The sympathetic nervous system:
The sympathetic nervous system is responsible for the body's fight or flight response, which involves activities such as increasing heart rate, dilating airways, and redirecting blood flow away from the digestive organs to skeletal muscles during times of stress or arousal. It typically inhibits digestive processes, including gastric motility, to conserve energy for immediate survival needs.

Correct Answer is C
Explanation
A) "I should limit my fluid intake while taking this medication":
This statement is incorrect. Furosemide is a loop diuretic that increases urine production to reduce fluid overload in conditions like heart failure or edema. It is essential for clients taking furosemide to maintain adequate hydration to prevent dehydration. Therefore, the client should not limit their fluid intake while taking this medication.
B) "My blood pressure will increase while I am taking this medication":
This statement is incorrect. Furosemide is primarily used to reduce blood pressure by promoting diuresis and reducing fluid volume. Therefore, it is unlikely that blood pressure would increase while taking this medication.
C) "I should take this medication in the morning rather than at night":
This is the correct answer. Furosemide is usually taken in the morning to prevent nocturia (excessive urination at night), as it can increase urinary frequency. Taking it earlier in the day allows for better fluid balance during waking hours and reduces the need to wake up frequently during the night to urinate.
D) "I should eat a diet low in potassium while taking this medication":
This statement is incorrect. Furosemide can cause potassium depletion as a side effect, so clients may be advised to consume potassium-rich foods or supplements unless contraindicated due to other medical conditions. However, it is not necessary to eat a diet low in potassium while taking furosemide unless specifically instructed by a healthcare provider.
Correct Answer is A
Explanation
A) "Take the medication with a full glass of water":
This is the correct answer. Docusate is a stool softener used to treat constipation by promoting the incorporation of water into the stool, making it softer and easier to pass. Taking docusate with a full glass of water helps facilitate its action by ensuring hydration and aiding in the softening of stool.
B) "Take this medication on an empty stomach":
Taking docusate on an empty stomach is not necessary. It can be taken with or without food. The primary consideration is to take it with an adequate amount of water to facilitate its stool-softening effect.
C) "Do not take this medication before bedtime":
There is no specific contraindication to taking docusate before bedtime. The timing of administration can vary based on individual preferences and bowel habits. Some individuals may prefer to take it before bedtime to promote a bowel movement in the morning, while others may take it at different times of the day.
D) "Expect abdominal pain with this medication":
Abdominal pain is an uncommon side effect of docusate. While it may occur in some individuals, it is not a common or expected reaction to the medication. Most people tolerate docusate well, but gastrointestinal side effects such as mild abdominal cramping, nausea, or diarrhea may occur in some cases.
