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 ["32"]

Explanation

Find the concentration of heparin in the solution:

Total heparin (units): 25,000 units

Volume of solution (mL): 500 mL

Heparin concentration (units/mL) = Total heparin (units) / Volume of solution (mL)

Heparin concentration (units/mL) = 25,000 units / 500 mL = 50 units/mL

Set up the flow rate equation:

Desired heparin infusion rate (units/hr): 1600 units/hr

Heparin concentration in solution (units/mL): 50 units/mL

Flow rate (mL/hr): We need to solve for this

Flow rate (mL/hr) = Desired heparin infusion rate (units/hr) / Heparin concentration (units/mL)

Calculate the flow rate (mL/hr):

Flow rate (mL/hr) = 1600 units/hr / 50 units/mL = 32 mL/hr (round to nearest whole number as requested)

Therefore, the nurse should set the IV pump to deliver approximately 32 mL/hr.

A. Milk B. Orange juice C. Grapefruit juice D. Coffee

Correct Answer is C

Explanation

A) Milk:
Milk is not known to interact significantly with verapamil. Therefore, there's no need for the client to avoid consuming milk while taking this medication.

B) Orange juice:
Orange juice does not typically interact with verapamil. However, calcium-containing foods and beverages, including orange juice, may reduce the absorption of verapamil when taken simultaneously. While the interaction is not severe, it's advisable for clients to separate the administration of verapamil from calcium-rich foods and beverages to optimize absorption.

C) Grapefruit juice:
This is the correct answer. Grapefruit juice contains compounds that inhibit the activity of cytochrome P450 enzymes, particularly CYP3A4, which are involved in the metabolism of many medications, including verapamil. Consuming grapefruit juice while taking verapamil can lead to elevated blood levels of the medication, increasing the risk of side effects and toxicity. Therefore, clients should avoid grapefruit juice while on verapamil therapy.

D) Coffee:
Coffee does not typically interact with verapamil. However, caffeine-containing beverages like coffee may exacerbate certain side effects of verapamil, such as dizziness or palpitations, due to their stimulant effects. Clients may be advised to limit caffeine intake or consume coffee in moderation while taking verapamil.
