A 70-year-old male receiving high-dose IV furosemide for heart failure complains of ringing in his ears and dizziness. His current labs show normal potassium and sodium levels. What is the nurse's most appropriate intervention?
Increase the infusion rate and check the patient's sodium levels again in 2 hours
Administer potassium supplements and continue the infusion
Reassure the patient that the symptoms are temporary and continue monitoring
Stop the furosemide infusion and notify the provider
The Correct Answer is D
A. Increasing the infusion rate may exacerbate the patient's symptoms and does not address the potential toxicity from the furosemide.
B. Normal potassium levels indicate that potassium supplementation is unnecessary and does not address the dizziness and ringing in the ears, which could suggest ototoxicity from furosemide.
C. While reassurance can help, the patient's symptoms indicate a potential adverse reaction to the medication that should not be ignored.
D. Stopping the furosemide infusion and notifying the provider is the most appropriate action due to the risk of ototoxicity and the need for further evaluation of the patient's symptoms.

Correct Answer is B
Explanation
A. In the assembly stage, other proteins and enzymes are involved in the packaging of viral components into new virions, not integrase.
B. During the integration stage, integrase is essential as it inserts the newly formed viral DNA into the host's genome, enabling the virus to utilize the host's cellular machinery for replication.
C. Integrase does not participate in the entry stage; this stage is facilitated by other proteins that aid in the fusion of the virus with the host cell membrane.
D. Integrase is not involved in reverse transcription; that process is facilitated by the enzyme reverse transcriptase, which converts viral RNA into DNA.
Correct Answer is D
Explanation
A. Cortisol levels are not directly affected by furosemide; monitoring for adrenal function is not a priority.
B. Bicarbonate levels are not specifically monitored for clients on furosemide; this medication's main effect does not relate directly to bicarbonate balance.
C. Albumin levels are not primarily affected by furosemide; although low albumin can affect fluid status, it is not the critical monitoring focus.
D. Potassium levels should be monitored because furosemide is a loop diuretic that can lead to hypokalemia, which is a common and significant side effect due to increased renal excretion of potassium.
