A patient is prescribed a drug that causes the selective stimulation of beta2 receptors. The nurse should assess the patient for what?
Hypoglycemia
Improved breathing
Tachycardia
Decreased pain
The Correct Answer is B
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.

Choice A rationale: Decreased strength is not the desired effect of baclofen.
Baclofen is a muscle relaxant and is expected to improve muscle tone rather than decrease strength.
Choice B rationale: Baclofen is used to suppress spasticity, which is a common symptom in patients with multiple sclerosis.
Choice C rationale: Improved muscle tone is the desired effect of baclofen, making this the correct choice.
Choice D rationale: Increased muscle resistance is not the desired effect of baclofen.
Correct Answer is B
Explanation
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.
