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 D
Explanation
A) Check the client's perianal skin integrity:
Assessing perianal skin integrity is important in the care of a client with ulcerative colitis, particularly due to the potential for diarrhea and irritation. However, this is not the first priority upon admission for an acute exacerbation.
B) Educate the patient on which foods the patient should eat:
Nutritional education is crucial in managing ulcerative colitis, but it is not the priority during the initial assessment and admission for an acute exacerbation. Stabilizing the client's condition and addressing immediate needs take precedence.
C) Investigate the client's emotional concerns:
While emotional support is important, particularly in chronic conditions like ulcerative colitis, assessing emotional concerns is not the first action required upon admission for an acute exacerbation. Physical stabilization and assessment of the client's condition are the initial priorities.
D) Review the client's electrolyte values:
This is the correct answer. During an acute exacerbation of ulcerative colitis, there is a risk of electrolyte imbalance due to diarrhea and fluid loss. Reviewing the client's electrolyte values is crucial to assess the severity of dehydration and electrolyte imbalances, which can have immediate implications for the client's treatment plan and stabilization.
Correct Answer is ["B","C","E"]
Explanation
A) Hypoglycemia:
Propranolol, a nonselective beta-blocking agent, can mask some of the symptoms of hypoglycemia, such as tachycardia and tremors, by blocking the sympathetic response. Therefore, it is not typically used in the treatment of hypoglycemia and may even exacerbate low blood sugar levels.
B) Arrhythmias:
Propranolol is commonly used in the treatment of various cardiac arrhythmias. By blocking beta-adrenergic receptors in the heart, it reduces the heart rate and myocardial contractility, thereby helping to control arrhythmias such as atrial fibrillation and ventricular tachycardia.
C) Hypertension:
Propranolol is effective in lowering blood pressure and is often prescribed for the management of hypertension. Its beta-blocking action reduces cardiac output and suppresses renin release, leading to decreased systemic vascular resistance and blood pressure.
D) Hypokalemia:
Propranolol does not have a direct role in the treatment of hypokalemia. While it can potentially exacerbate hypokalemia through its effects on potassium metabolism, it is not a primary treatment for this electrolyte imbalance.
E) Angina:
Propranolol is indicated for the treatment of angina pectoris, particularly in cases of stable angina. By reducing myocardial oxygen demand through its negative chronotropic and inotropic effects, it helps relieve anginal symptoms and improve exercise tolerance."
