Finally, it includes a nursing process section, offering guidance on patient assessment, planning, implementation, and evaluation related to the administration of these drugs.

Ch.25 provides a comprehensive overview of integumentary problems, focusing on skin disorders and cancers. It covers various topics including environmental hazards like sun exposure and drug photosensitivity, different types of skin cancers such as basal cell carcinoma, squamous cell carcinoma, and melanoma, as well as their risk factors, clinical manifestations, and treatments. The source also examines common skin infections caused by bacteria, viruses, fungi, infestations, and insect bites, along with allergic and benign skin problems, detailing their causes, symptoms, and management. Finally, it discusses various diagnostic and surgical procedures for skin problems, including phototherapy, laser therapy, cryosurgery, and skin grafting, emphasizing essential nursing management practices like wound care, preventing infection, and addressing the psychosocial impact of these conditions.

Ch 24 provides a detailed overview of the integumentary system, encompassing the structure and functions of the skin, hair, and nails, along with associated glands. It explores the changes that occur with aging and emphasizes the importance of both subjective and objective data collection for assessing this system. The source further outlines various types of skin lesions, explains how to perform a physical assessment, highlights assessment variations in different skin tones, and describes common diagnostic studies used in dermatology.

Ch22 provides an in-depth exploration of the visual system, covering its structures and functions. It discusses various visual problems, ranging from refractive errors like myopia and hyperopia to more serious conditions such as cataracts, retinal detachment, age-related macular degeneration, and glaucoma. The text emphasizes the importance of assessment and management for these conditions, including diagnostic studies, medical and surgical interventions, and crucial nursing considerations related to patient care, health promotion, and coping with vision loss, particularly in the context of aging.

Ch. 43 provides an in-depth look at antimalarial, antiprotozoal, and anthelmintic drugs, focusing on their use in treating parasitic infections. It outlines the infectious processes of malaria, other protozoal diseases, and helminthic infections, comparing their signs and symptoms. The text details various drug classifications, including their mechanisms of action, indications, and potential adverse effects, while also discussing nursing care considerations for patients receiving these medications. Key terms related to these infections and treatments are defined.

Ch42 provides an overview of antifungal drugs, including their classifications, mechanisms of action, and clinical uses.
