The mental health nursing instructor is talking with the class about depression. what deficiency does the instructor explain will result in depression?
Norepinephrine, dopamine, and serotonin
Epinephrine, Norepinephrine, and Acetylcholine
Acetylcholine, gamma-aminobutyric acid, and serotonin
gamma-aminobutyric acid, dopamine, and epinephrine
The Correct Answer is A
A) Norepinephrine, dopamine, and serotonin:
Depression has been strongly linked to deficiencies in certain neurotransmitters in the brain, specifically norepinephrine, dopamine, and serotonin. These neurotransmitters play significant roles in regulating mood, emotions, and behavior. When their levels are low, individuals may experience symptoms of depression, such as sadness, low energy, anhedonia (inability to feel pleasure), and difficulty concentrating. Antidepressant medications often work by increasing the availability of these neurotransmitters in the brain.
B) Epinephrine, Norepinephrine, and Acetylcholine:
While norepinephrine plays a key role in depression, epinephrine and acetylcholine are not typically highlighted as the primary neurotransmitters involved in depression. Epinephrine (also known as adrenaline) is more associated with the body’s stress response and fight-or-flight reaction. Acetylcholine is involved in memory and learning processes, but it is not the primary neurotransmitter related to depression.
C) Acetylcholine, gamma-aminobutyric acid, and serotonin:
Acetylcholine and gamma-aminobutyric acid (GABA) are involved in many brain functions, but they are not the primary neurotransmitters linked to depression. While GABA may play a role in mood regulation, it is not typically associated with depression in the same way that serotonin, norepinephrine, and dopamine are. Serotonin is the exception in this answer
D) Gamma-aminobutyric acid, dopamine, and epinephrine:
Although dopamine is involved in depression, gamma-aminobutyric acid (GABA) and epinephrine are not the key neurotransmitters associated with the pathophysiology of depression. Epinephrine primarily affects the stress response, and while GABA does influence mood and anxiety, it is not the main neurotransmitter linked to depression itself.

Correct Answer is A
Explanation
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.
Correct Answer is C
Explanation
A) Suspect worsening of the anxiety disorder:
While it is possible that the patient's anxiety disorder is worsening, the more likely explanation for the reduced effectiveness of lorazepam is the development of drug tolerance. Over time, patients may require higher doses of a medication to achieve the same therapeutic effect, especially with medications like lorazepam that are used chronically.
B) Contact the provider to discuss changing to another benzodiazepine:
Changing to another benzodiazepine might be an option, but it is more likely that tolerance to lorazepam is the cause of the reduced effect, not an issue with the specific drug. Tolerance is common with long-term use of benzodiazepines, and switching drugs may not address the underlying issue. The first step would be to assess the current medication regimen and discuss possible adjustments with the provider.
C) Understand that the patient has developed tolerance to this drug:
Tolerance occurs when the body becomes accustomed to the effects of a medication over time, requiring higher doses to achieve the same therapeutic effect. This is a common phenomenon with benzodiazepines like lorazepam, which are often used for long periods to manage anxiety. As the patient has been taking lorazepam for six months, this reduced effectiveness is likely due to the development of tolerance, rather than a worsening of the anxiety disorder.
D) Notify the provider and discuss increasing the dose of lorazepam:
While increasing the dose of lorazepam could temporarily relieve symptoms, it is not the most appropriate first step. The nurse should first consider the possibility of tolerance and discuss this with the provider before increasing the dose. Long-term increases in benzodiazepine dosages can increase the risk of side effects, dependency, and withdrawal symptoms.
