What is Alprazolam therapeutic use?

Correct Answer: B

Rationale: Alprazolam is a medication commonly used to treat anxiety disorders. It belongs to a class of drugs called benzodiazepines, which work by enhancing the effects of a neurotransmitter in the brain called gamma-aminobutyric acid (GABA). This leads to a calming effect on the brain and central nervous system, helping to reduce feelings of anxiety and promote relaxation. Alprazolam is not indicated for preventing thrombus formation, decreasing the risk of stroke, or increasing urinary output.

Correct Answer: D

Rationale: Intravenous injection is a route of administration where a substance is delivered directly into the veins. While it is true that intravenous injection tends to produce more immediate adverse reactions, can lead to high drug concentrations, and poses a risk of penetrating an artery instead of a vein, it is not considered convenient, safe, or economical compared to other routes of administration. Intravenous injections require skilled personnel to administer, careful monitoring, and specialized equipment, which can add to the cost and complexity of treatment. Additionally, there is always a potential risk of infection or other complications associated with intravenous injection, which can make it less safe compared to other routes like oral or topical administration.

Correct Answer: D

Rationale: High threshold mechanoreceptors are a type of sensory receptor that responds to intense mechanical stimulation, such as pressure or stretching. When these receptors are activated, they can trigger a cascade of events leading to the release of endogenous opioids, which are natural pain-relieving compounds. The activation of high threshold mechanoreceptors ultimately leads to analgesia, a decreased sensitivity to pain. This is a protective mechanism that helps the body cope with potentially harmful stimuli by reducing the perception of pain.

Correct Answer: D

Rationale: Beta1-selective adrenergic blocking agents have an advantage over the nonselective beta-blockers in some cases. Because they do not usually block beta2-receptor sites, they do not block the sympathetic bronchodilation that is so important for patients with lung diseases or allergic rhinitis. Consequently, these drugs are preferred for patients who smoke or who have asthma, any other obstructive pulmonary disease, or seasonal or allergic rhinitis. Nonselective adrenergic blocking agents block both alpha- and beta-adrenergic receptors exacerbating respiratory conditions by the loss of norepinephrine’s effect of bronchodilation. Nonselective alpha-adrenergic blocking agents are not used to treat angina. Alpha1-selective adrenergic blocking agents are not used to treat angina. The nurse should consider the patient’s medical history when selecting adrenergic blocking agents to ensure safe and effective treatment.
