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
Rationale:
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
Rationale:
A. Mostly cloudy: This option does not refer to a medication and is therefore irrelevant in this context.
B. Acyclovir: This is the correct medication for treating varicella-zoster virus, as it is an antiviral drug effective in managing symptoms and reducing the duration of the infection.
C. Vancomycin: This antibiotic is used to treat serious bacterial infections and is not indicated for viral infections like varicella-zoster.
D. Gentamicin: This is an aminoglycoside antibiotic that is ineffective against viral infections and is used primarily for bacterial infections.
E. Quinine: This medication is used to treat malaria and is not relevant for varicella-zoster virus treatment.
Correct Answer is B
Explanation
Rationale:
A. Nitrates: Nitrates are primarily used to manage angina or heart conditions and are unrelated to acetazolamide or its potential for allergic reactions.
B. Sulfa-based medications: Acetazolamide is a carbonic anhydrase inhibitor that contains sulfonamide groups. Clients with a sulfa allergy may experience a cross-sensitivity reaction, so it's important to confirm any history of sulfa allergies before administration.
C. Mostly cloudy: This option does not relate to any medication classification and is incorrect.
D. Antilipemic agents: Antilipemics are used to lower cholesterol and are not related to acetazolamide or its potential for allergic reactions.
E. Proton pump inhibitors: Proton pump inhibitors are used to reduce stomach acid and do not have a known cross-sensitivity with acetazolamide.
