When a patient is taking an adrenergic agonist drug, the nurse expects to observe which effect?
Constricted pupils
Increased heart rate
Bronchial constriction
Increased GI peristalsis
The Correct Answer is B
A. Constricted pupils: Adrenergic agonist drugs typically cause pupil dilation (mydriasis), not constriction.
B. Increased heart rate: Adrenergic agonists stimulate the sympathetic nervous system, leading to increased heart rate (positive chronotropic effect) and increased cardiac contractility (positive
inotropic effect).
C. Bronchial constriction: Adrenergic agonists typically cause bronchodilation, not constriction.
D. Increased GI peristalsis: Adrenergic agonists usually inhibit GI motility, leading to decreased GI peristalsis and potentially constipation

Correct Answer is B
Explanation
A. A lithium level of 0.9 mEq/L falls within the therapeutic range for lithium, so it is not too low.
B. A lithium level of 0.9 mEq/L is within the therapeutic range for lithium maintenance therapy, which typically ranges from 0.6 to 1.2 mEq/L. Therefore, it is considered therapeutic.
C. Lithium is commonly monitored with blood levels to ensure therapeutic efficacy and to prevent toxicity.
D. A lithium level of 0.9 mEq/L is not too high; it is within the therapeutic range.
Correct Answer is A
Explanation
A. The patient's respiratory rate: Morphine sulfate is an opioid analgesic that can cause
respiratory depression as a side effect. Therefore, assessing the patient's respiratory rate is crucial before administering the medication to ensure it is within normal limits.
B. The appearance of the incision: While assessing the incision is important for overall surgical site assessment, it's not directly related to the administration of morphine sulfate.
C. The date of the patient's last bowel movement: Bowel movements may be impacted by anesthesia and surgery, but they are not directly relevant to assessing the safety of administering morphine sulfate.
D. The patient's pulse rate: Pulse rate is important for overall assessment of the patient's
condition but may not directly indicate the need for or safety of administering morphine sulfate.
