A nurse administers a medication that activates dopamine receptors. The nurse should assess the patient for which intended effect: 1/2.

Choice A rationale: Atropine is not primarily used to prevent anxiety. Its main use is to increase heart rate by blocking vagal effects on the heart.
Choice B rationale: Atropine is commonly used to prevent or treat bradycardia, particularly during anesthesia induction, when vagal stimulation can lead to significant slowing of the heart rate.
Choice C rationale: Dry mouth is a common side effect of atropine, not its primary use. Atropine is not given to prevent dry mouth.
Choice D rationale: Atropine is not used to prevent hypertension. Its primary cardiovascular effect is to increase heart rate.

Choice A rationale: A blood pressure reading of 72/56 mmHg may be expected after spinal anesthesia. The nurse should continue to monitor the blood pressure to ensure it stabilizes within an acceptable range for the individual patient.
Choice B rationale: Headache is a common side effect of spinal anesthesia, and the nurse should assess for this but should not be the first action with the given blood pressure reading.
Choice C rationale: Administering oxygen by nasal cannula may not be necessary based solely on the blood pressure reading after spinal anesthesia.
Choice D rationale: Elevating the client's feet is not the first intervention for a blood pressure reading of 72/56 mmHg after spinal anesthesia. It may be considered if the blood pressure remains low and symptoms of hypotension are present.
