When there is stimulation of the sympathetic nervous system (SNS), blood is diverted away from the gastrointestinal (GI) tract. What might the nurse assess that would indicate this diversion of blood flow to the GI tract?

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.

A) Breath sounds: Prior to administering Atrovent (Ipratropium Bromide), it is essential for the nurse to assess the child’s breath sounds. Ipratropium is an anticholinergic medication used to relieve bronchospasm in conditions like asthma or chronic obstructive pulmonary disease (COPD). By evaluating breath sounds, the nurse can assess the severity of the respiratory condition and monitor for any wheezing or crackles, which may indicate the need for further intervention or adjustment of the treatment.
B) Cardiac disorders: While some caution may be warranted in patients with cardiac disorders when using certain medications (e.g., sympathomimetics), Ipratropium Bromide is an anticholinergic agent that primarily affects the respiratory system. It is not directly contraindicated in children with cardiac disorders, so assessing for cardiac conditions is not the most critical initial assessment when administering this drug.
C) Recent injuries: Recent injuries do not specifically relate to the need for assessment prior to administering Ipratropium. This medication targets the lungs and airways, so assessing for recent injuries would not be as pertinent unless the injuries impacted the child’s ability to breathe (e.g., rib fractures, lung trauma).
D) Hypertension: Hypertension is not a primary concern when administering Ipratropium Bromide. While anticholinergic drugs should be used cautiously in certain individuals (e.g., those with glaucoma or urinary retention), hypertension is not a contraindication for this medication. It would be more critical to assess for respiratory status, particularly breath sounds, to evaluate the efficacy of the treatment.
