A nurse is caring for a client whose throat culture is positive for group A streptococcus 24 hours after a rapid strep test (RST) was negative. Which of the following actions is the nurse's priority?

Choice A reason:
This choice suggests a pH of 7.50, which is indicative of alkalosis, and not typically expected in a client with chronic kidney disease (CKD). CKD often leads to metabolic acidosis due to the accumulation of acids in the body as the kidneys fail to excrete them. The HCO₃⁻ level of 20 mEq/L is slightly lower than the normal range (22-26 mEq/L), and the PaCO₂ of 32 mm Hg is within the normal range (35-45 mm Hg), but these values do not align with the expected acidosis associated with CKD.

Choice B reason:
This set of values is consistent with metabolic acidosis, which is commonly seen in clients with CKD. A pH of 7.25 indicates acidemia, and an HCO₃⁻ level of 19 mEq/L is below the normal range, suggesting a primary metabolic acidosis. The PaCO₂ of 30 mm Hg is at the lower end of the normal range, which may indicate a compensatory respiratory response to the metabolic acidosis.

Choice C reason:
A pH of 7.30, while on the lower side, is not as acidic as one would expect in a client with CKD. The HCO₃⁻ level of 26 mEq/L is within the normal range, and a PaCO₂ of 50 mm Hg suggests respiratory acidosis, which is not the primary disorder in CKD.

Choice D reason:
This choice indicates a pH of 7.55, which is too alkaline and not characteristic of CKD, where metabolic acidosis is the expected finding. An HCO₃⁻ level of 30 mEq/L is higher than the normal range, suggesting metabolic alkalosis. The PaCO₂ of 31 mm Hg is slightly below the normal range, possibly indicating a compensatory response, but it does not align with the metabolic acidosis typically seen in CKD.

Choice A reason:
This statement is correct. Medications for genital herpes, such as antiviral drugs, can help decrease the severity and frequency of symptoms but do not cure the infection. The herpes simplex virus remains in the body and can cause recurrent outbreaks.

Choice B reason:
This statement is incorrect and indicates a misunderstanding. Genital herpes is caused by the herpes simplex virus and cannot be treated with antibiotics, which are effective only against bacterial infections. Antiviral medications are used to treat viral infections like genital herpes.

Choice C reason:
This statement is incorrect. Genital herpes can be transmitted to a partner even when lesions are not present. The virus can be shed from the skin even without visible symptoms, a process known as asymptomatic viral shedding.

Choice D reason:
This statement is incorrect. Even after finishing a course of medication, the risk of transmitting genital herpes to a partner remains because the virus persists in the body. Safe sex practices, including the use of condoms, can help reduce the risk of transmission.
