Rationale: The activated partial thromboplastin time (aPTT) is the laboratory value used to monitor the effectiveness of heparin therapy. The aPTT should be maintained at 1.5 to 2 times the normal level to ensure therapeutic anticoagulation. Monitoring aPTT helps healthcare providers adjust heparin doses to achieve the desired anticoagulant effects and prevent complications such as bleeding or clotting.

Rationale: The correct answer is to instruct the client to avoid salt substitutes. Lisinopril, an ACE inhibitor, can lead to hyperkalemia, so it is essential to avoid salt substitutes containing potassium, which can further increase potassium levels in the body. This instruction aims to prevent potential adverse effects and ensure the client's safety while taking Lisinopril.

Correct Answer: D

Rationale: Metformin can lead to lactic acidosis, especially in individuals with impaired renal function. Monitoring the client's serum creatinine levels is crucial to assess kidney function because Metformin is eliminated by the kidneys, and impaired renal function can increase the risk of adverse effects.

Correct Answer: A

Rationale: To verify trough levels of a medication, the healthcare professional should obtain a blood specimen immediately before administering the next dose of medication. This timing ensures an accurate representation of the medication's lowest concentration in the bloodstream, which is crucial for therapeutic monitoring and dose adjustments.
