The nurse assess that the patient is having a sympathetic response when noting what manifestation?
Decrease in heart rate and perfusion, and an increase in inflammatory response
Increase motility and secretion in the GI tract, constriction of bronchi and pupils
Increase in blood pressure, bronchodilation, and decrease bowel sounds
Decrease in sweating, decrease in respiration, and pupil constriction
The Correct Answer is C
A) Decrease in heart rate and perfusion, and an increase in inflammatory response: These manifestations suggest parasympathetic nervous system activation, not the sympathetic response. The sympathetic system generally increases heart rate and perfusion to support "fight or flight" responses. Additionally, inflammatory responses are more immune-related and are not a direct effect of sympathetic activation.
B) Increase motility and secretion in the GI tract, constriction of bronchi and pupils: This is characteristic of parasympathetic nervous system activity. The parasympathetic system stimulates digestion (increased motility and secretion) and causes bronchoconstriction and pupil constriction (miosis). The sympathetic nervous system, in contrast, inhibits GI motility and causes bronchodilation and pupil dilation.
C) Increase in blood pressure, bronchodilation, and decrease bowel sounds: These are hallmark signs of sympathetic nervous system activation. When the sympathetic system is activated during stress or danger, it leads to vasoconstriction, which increases blood pressure. Bronchodilation occurs to allow more oxygen intake, and GI motility decreases (manifested as reduced bowel sounds) to redirect energy to more vital functions, like increased circulation to muscles.
D) Decrease in sweating, decrease in respiration, and pupil constriction: These signs suggest parasympathetic or a relaxed state. The sympathetic nervous system typically increases sweating, respiration, and causes pupil dilation to prepare the body for increased activity. Decreased sweating and respiration, along with pupil constriction, would not be consistent with the sympathetic response.

Correct Answer is D
Explanation
A) Phagocytosis: Phagocytosis refers to the process by which a cell engulfs large particles, such as pathogens or debris, and brings them into the cell. It is not related to the movement of hormones across the cell membrane.
B) Endocytosis: Endocytosis is the process where a cell engulfs substances from the external environment and brings them into the cell. However, this term is typically used when substances like nutrients or larger molecules are taken into the cell, not when hormones are being secreted out of the cell.
C) Pinocytosis: Pinocytosis is a type of endocytosis in which the cell engulfs extracellular fluid and dissolved substances. It is often referred to as "cell drinking" and involves the uptake of fluids, not the secretion of hormones across the membrane.
D) Exocytosis: This is the correct answer. Exocytosis is the process by which substances, such as hormones or neurotransmitters, are transported from inside the cell to the outside by vesicles that fuse with the cell membrane. In the case of hormones, they are synthesized within the cell and then released into the extracellular space via exocytosis, enabling them to reach their target sites.
Correct Answer is A
Explanation
A) Reducing some of the tremors: Benztropine (Cogentin) is an anticholinergic medication commonly used in the treatment of Parkinson's disease to help manage symptoms. It works by blocking the effects of acetylcholine, which can help to restore the balance between acetylcholine and dopamine in the brain. This helps reduce symptoms like tremors and rigidity, which are common in Parkinson’s disease. Although it may not completely eliminate these symptoms, it can significantly reduce tremors, making this the most accurate effect of the drug.
B) Improving mental function: Benztropine is not intended to improve mental function. In fact, anticholinergic medications like benztropine can sometimes cause cognitive side effects, including memory problems or confusion, particularly in older patients. While the drug is effective in reducing motor symptoms, it is not used to enhance cognitive abilities in Parkinson’s disease.
C) Helping the patient to walk faster: Benztropine does not directly improve gait speed or help a patient walk faster. The drug primarily targets motor symptoms like tremors and rigidity rather than improving bradykinesia (slowness of movement), which is often the cause of walking difficulty in Parkinson’s patients. Medications such as levodopa or dopamine agonists are typically used to address issues related to bradykinesia and movement speed.
D) Minimizing symptoms of bradykinesia: While benztropine can help manage tremors and rigidity, it is not particularly effective for bradykinesia, which is the hallmark symptom of Parkinson’s disease. Bradykinesia is best addressed with dopaminergic medications like levodopa or dopamine agonists. Therefore, benztropine would not be the first choice for minimizing bradykinesia symptoms.
