A nurse is caring for a client who is newly diagnosed with HIV. Prior to discharge, the nurse would anticipate the client verbalizing which of the following statements?

A) Simvastatin: Simvastatin is a medication used to lower cholesterol levels and does not typically require monitoring of blood pressure before or after administration. While statins may have some indirect cardiovascular benefits, blood pressure is not directly affected by this medication, so it is not necessary to assess blood pressure before or after administering simvastatin.

B) Metoprolol: This is the correct answer. Metoprolol is a beta-blocker commonly used to treat hypertension and other cardiovascular conditions. It works by reducing heart rate and blood pressure. Therefore, it is important to assess the client's blood pressure both before and after administering metoprolol to ensure the medication is having the desired effect and to detect any adverse changes, such as hypotension or bradycardia.

C) Acetylsalicylic Acid (Aspirin): Aspirin is primarily used for its antiplatelet effect, such as for preventing heart attacks or strokes, and it does not have a significant direct impact on blood pressure. While aspirin can have side effects, such as gastrointestinal irritation or bleeding, blood pressure monitoring is generally not necessary before or after administering aspirin.

D) Metformin: Metformin is used to manage type 2 diabetes by helping control blood glucose levels. It does not directly affect blood pressure, so routine blood pressure assessment is not required before or after giving metformin. However, monitoring for side effects like gastrointestinal distress or lactic acidosis is important, but blood pressure is not a priority for this medication.

A) Obtain a 12-lead ECG:
The client’s potassium level of 6.6 mEq/L is significantly elevated which places the patient at risk for cardiac arrhythmias. Elevated potassium levels can cause dangerous changes in the electrical activity of the heart, leading to peaked T waves, widened QRS complexes, and even cardiac arrest. A 12-lead ECG is necessary to assess the heart's electrical activity and to identify any potential arrhythmias

B) Request an electroencephalogram (EEG):
An EEG is used to assess brain activity and is typically indicated for conditions such as seizures or epilepsy. This client’s laboratory findings do not suggest a neurological concern that would warrant an EEG.

C) Assess for Chvostek's sign:
Chvostek's sign is used to assess for hypocalcemia or tetany, where a twitching of the facial muscles occurs upon tapping the facial nerve. However, the client’s primary issue here is elevated potassium levels, which are a more immediate concern than hypocalcemia. Hyperkalemia can have more severe and urgent consequences, particularly for the heart, so Chvostek's sign is not the priority at this time.

D) Obtain a chest X-ray:
A chest X-ray is not indicated based on the client’s current electrolyte imbalance or renal failure status. While a chest X-ray may be useful for various other concerns, the client’s elevated potassium level is the primary issue, and the priority intervention is to assess and manage the potential for cardiac arrhythmias with a 12-lead ECG.
