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 C
Explanation
A. Fusion Inhibitors work by preventing the virus from entering the host's cells but do not inhibit RNA from forming DNA.
B. Integrase Inhibitors block the integration of viral DNA into the host's DNA but do not directly inhibit the reverse transcription process.
C. Nucleoside Reverse Transcriptase Inhibitors (NRTIs) inhibit reverse transcriptase, the enzyme responsible for converting viral RNA into DNA, thus directly targeting this crucial stage of the HIV lifecycle.
D. Protease Inhibitors inhibit the protease enzyme involved in the maturation of the virus but do not affect the reverse transcription process.
Correct Answer is B
Explanation
A. Metabolic alkalosis is characterized by an increased pH and increased HCO3 levels, which does not fit the provided values.
B. The low HCO3 of 18 mEq indicates a metabolic acidosis, as the body is unable to retain enough bicarbonate to balance the acid levels, and the pH is also low at 7.30, confirming acidosis.
C. Respiratory alkalosis would show a high pH and low PaCO2, which is not the case here.
D. Respiratory acidosis would be indicated by a high PaCO2 and a low pH, but the HCO3 level is low, indicating a metabolic issue rather than a respiratory one.
