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

Answer and Explanation

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 A

Explanation

A) The sympathetic nervous system is responsible for "fight or flight":
This is the correct answer. The sympathetic nervous system is responsible for the "fight or flight" response, which prepares the body to react to perceived threats or stressors by increasing heart rate, dilating pupils, redistributing blood flow, and releasing stress hormones such as adrenaline and noradrenaline.

B) The sympathetic nervous system helps us to rest and digest:
This statement is incorrect. The parasympathetic nervous system is responsible for the "rest and digest" response, which promotes relaxation, digestion, and conservation of energy.

C) The sympathetic nervous system includes the cranial nerves:
This statement is incorrect. The sympathetic nervous system is primarily associated with the thoracolumbar region of the spinal cord and does not include the cranial nerves, which are primarily associated with the parasympathetic nervous system.

D) The sympathetic nervous system can lower blood pressure:
This statement is incorrect. The sympathetic nervous system typically increases blood pressure as part of the "fight or flight" response by increasing heart rate and constricting blood vessels to redirect blood flow to vital organs and muscles.

A. Migraines B. Diverticulitis C. Hypertension D. Eczema

Correct Answer is C

Explanation

A) Migraines:
Pseudoephedrine is not contraindicated for migraines. In fact, it is sometimes used in combination with other medications to alleviate symptoms of sinus congestion associated with migraines.

B) Diverticulitis:
Pseudoephedrine is not contraindicated for diverticulitis. However, it may cause gastrointestinal side effects such as abdominal discomfort or constipation, which could exacerbate symptoms in individuals with diverticulitis. Therefore, caution should be exercised when using pseudoephedrine in these clients.

C) Hypertension:
This is the correct answer. Pseudoephedrine is a sympathomimetic drug that can cause vasoconstriction and increase blood pressure. Therefore, it is contraindicated in clients with hypertension or cardiovascular disease, as it may exacerbate these conditions and increase the risk of adverse cardiovascular events such as hypertensive crisis or stroke.

D) Eczema:
Pseudoephedrine is not contraindicated for eczema. However, it may cause dryness of the skin and exacerbate existing dermatological conditions. Clients with eczema should use pseudoephedrine cautiously and monitor for any worsening of their skin condition.
