This design involves a comprehensive and detailed exploration of a single individual or a specific situation, allowing for an in-depth analysis of various aspects related to the subject. Since Nurse Carmi is focusing on studying only one subject, a case study design will enable her to gather detailed information, delve deep into the complexities of the individual's experiences, behaviors, and outcomes related to domestic violence. This design will provide a rich and holistic understanding of the single case being studied, offering valuable insights and potential implications for practice and intervention strategies.

Rationale: Dry cough is the most commonly reported adverse effect associated with lisinopril therapy. Lisinopril is an ACE inhibitor, and the mechanism behind the cough is not completely understood but is thought to be related to the accumulation of bradykinin and substance P. This annoying dry cough can be a persistent issue for some patients on lisinopril, and it typically resolves once the medication is discontinued. Patients who experience this side effect should not ignore it and should consult their healthcare provider for further evaluation and possible alternative medication options. Hyperkalemia, hypertension, and bradycardia are not commonly associated adverse effects of lisinopril therapy.
