A nurse is monitoring a client who is receiving a continuous IV infusion of dopamine. Which of the following findings requires immediate intervention by the nurse?
Heart rate 105/min
Infiltration of the peripheral IV
Increased blood pressure
Occasional premature ventricular complexes (PVCs)
The Correct Answer is B
A. A heart rate of 105/min is slightly elevated, but it does not require immediate intervention unless the client is symptomatic or has other concerning signs.
B. Infiltration of the peripheral IV requires immediate intervention, as it can lead to tissue damage and prevent the medication from being effectively delivered. The nurse should stop the infusion, assess the site, and take appropriate action.
C. Increased blood pressure is a common effect of dopamine administration and does not necessarily require urgent intervention unless it becomes critically high or is associated with other adverse symptoms.
D. Occasional PVCs can occur during dopamine infusion and can be monitored unless they become frequent or symptomatic; they typically do not require immediate intervention.

Correct Answer is B
Explanation
A. Hydrochlorothiazide does not prevent angiotensin II from binding with receptor sites; this action is typically associated with ACE inhibitors or angiotensin receptor blockers.
B. Hydrochlorothiazide decreases the reabsorption of sodium and water in the distal renal tubule, which leads to increased urine output and decreased blood volume, effectively lowering blood pressure.
C. Hydrochlorothiazide does not block beta receptors; this is the mechanism of action for beta-blockers.
D. Hydrochlorothiazide does not promote the movement of extravascular fluids into the vascular compartment; instead, it reduces blood volume by promoting diuresis.
Correct Answer is D
Explanation
A. Cataracts are not a contraindication for cholinesterase inhibitors like neostigmine.
B. Hypertension is not a direct contraindication for cholinesterase inhibitor therapy, although caution may be exercised depending on the overall health status of the client.
C. Hypothyroidism is not contraindicated for cholinesterase inhibitors; however, it should be managed appropriately.
D. Peptic ulcer disease is a significant contraindication for cholinesterase inhibitors like neostigmine because these medications can increase gastric secretions and motility, potentially exacerbating ulcer conditions and leading to complications.
