Question 1 of 5
The nurse administers an adrenergic blocking agent in order to prevent release of what neurotransmitter?
Correct Answer: B
Rationale: Adrenergic blocking agents prevent norepinephrine from being released from the adrenal medulla or from the nerve terminal from activating the receptor, which blocks sympathetic nervous system effects. Epinephrine, serotonin, and GABA are not associated with this process. Norepinephrine is the primary neurotransmitter targeted by these agents, as it plays a key role in the sympathetic nervous system's fight-or-flight response.
Question 2 of 5
What is the therapeutic range for lithium?
Correct Answer: D
Rationale: The therapeutic range for lithium is generally considered to be 0.6-1.2 mmol/L (which is equivalent to 0.6-1.2 mEq/L). However, some sources may state a slightly wider range of 0.5-1.5 mEq/L. It is important to note that individual patient factors and clinical judgment should also be considered when interpreting lithium levels. Levels below the therapeutic range may be subtherapeutic and not provide the desired therapeutic effect, while levels above the range may result in toxicity and adverse effects. Monitoring lithium levels regularly is important to ensure they remain within the therapeutic range.

Question 5 of 5
What is the therapeutic use of Albuterol?
Correct Answer: A
Rationale: Albuterol is a medication that belongs to the class of beta-2 adrenergic agonists, which are primarily used for bronchodilation. It works by relaxing the muscles in the airways, allowing them to widen and making breathing easier for individuals with conditions such as asthma, chronic obstructive pulmonary disease (COPD), and other respiratory disorders. Albuterol helps to relieve symptoms of bronchospasm, such as wheezing, shortness of breath, and chest tightness. It is commonly used as a rescue inhaler for quick relief of acute bronchospasm.
