Hypoglycemia

Improved breathing

Tachycardia

Decreased pain

Answer and Explanation

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.

Correct Answer is A

Explanation

Choice A rationale: Patient-controlled analgesia (PCA) devices provide a controlled dose of medication when the patient presses the button. However, the onset of action for morphine is typically faster than 10 minutes.
Choice B rationale: PCA devices often have a lock-out period to prevent patients from administering too many doses too quickly and risking overdose.
Choice C rationale: Patient-controlled analgesia is designed for the patient to self- administer the medication. Allowing family members to press the button may lead to inaccurate dosing.
Choice D rationale: Morphine should be administered as needed, not preemptively.
Administering the medication 10 minutes before physical therapy could result in excessive sedation.

A. "The medicine will help me to breathe." B. "I can use the nasal spray as often as needed." C. "Increasing my oral fluids will help with hydration."

Correct Answer is B

Explanation

Choice A rationale: Phenylephrine can help relieve nasal congestion and improve breathing.
Choice B rationale: Using the nasal spray as often as needed can lead to rebound congestion and should be avoided. Phenylephrine nasal spray should be used according to the healthcare provider's instructions.
Choice C rationale: Increasing oral fluids can help with hydration, especially when using a decongestant nasal spray.
