A patient who has been diagnosed with rheumatoid arthritis for 1 month and has generalized symptoms is taking high-dose NSAIDS and an oral glucocorticoid. The provider has prescribed methotrexate. The patient asks the nurse why methotrexate is necessary since pain and swelling have been well controlled with the other medications. The nurse will tell the patient that:
A methotrexate regimen will prevent fatal toxicities.
Starting methotrexate early can delay the disease process of joint degeneration.
Starting methotrexate now will help increase life expectancy.
The Correct Answer is B
Choice A rationale: While methotrexate can help prevent fatal toxicities associated with rheumatoid arthritis, this is not the primary reason for its use in this context.
Choice B rationale: This is correct. Starting methotrexate early in the course of rheumatoid arthritis can help delay the disease process of joint degeneration and prevent irreversible damage.
Choice C rationale: While controlling symptoms is important for the patient's quality of life, starting methotrexate is more about preventing joint damage and progression of the disease than increasing life expectancy.

Correct Answer is B
Explanation
Choice A rationale: Epinephrine does increase the speed of conduction, but it does not significantly contribute to gluconeogenesis.
Choice B rationale: Epinephrine is used in cardiac arrest to increase heart rate, contractility, and conduction. In asthma, it causes bronchodilation.
Choice C rationale: While epinephrine can cause some vasodilation, it is not a primary indication for its use in cardiac arrest or status asthmaticus.
Choice D rationale: Epinephrine causes bronchodilation, not bronchoconstriction.
Correct Answer is B
Explanation
Choice A rationale: Selective stimulation of beta2 receptors is less likely to cause hypoglycemia; beta1 receptors are more involved in glucose metabolism.
Choice B rationale: Beta2 receptors are primarily found in the bronchioles of the lungs, and their stimulation leads to improved breathing.
Choice C rationale: Tachycardia is more commonly associated with the selective stimulation of beta1 receptors.
Choice D rationale: Beta2 receptors are not typically involved in the modulation of pain perception.
