The skin also The skin, also called integument, is the largest organ acts as a reservoir for food and water. The (hair, nails, and glands), the skin makes up the skin consists of two distinct layers: the epidermis integumentary system. A subcutaneous layer of tissue tinct tissues includes glands that produce several binds the skin to underlying structures. The skin covers and protects all outer surfaces The outer layer, the (1) epidermis, is relatively thin of the body and performs many vital functions, over most areas but is thickest on the palms of the including the sense of touch. Although the epi- dermis is composed of several sublayers called strata, the (2) stratum corneum and the (3) basal Skin layer, which is the deepest layer, are of greatest The skin protects underlying structures from importance. Beneath the skin’s surface is an intricate net- cells that lack a blood supply and sensory recep- work of nerve fibers that register sensations of tors. The basal layer is the only layer functions of the skin include protecting the body of the epidermis that is composed of living cells Anatomy and Physiology Key Terms This section introduces important terms, along with their definitions and pronunciations. As these cells move Production of melanocytes is genetically regulated toward the stratum corneum to replace the cells and, thus, inherited. Local accumulations of that have been sloughed off, they die and become melanin are seen in pigmented moles and freckles. An absence of pigment in the skin, eyes, and hair The relatively waterproof characteristic of keratin is most likely due to an inherited inability to pro- prevents body fluids from evaporating and mois- duce melanin. The entire process by melanin has a marked deficiency of pigment in the which a cell forms in the basal layer, rises to the eyes, hair, and skin and is known as an albino. Dermis In the basal layer, special cells called melanocytes The second layer of the skin, the (4) dermis, also produce a black pigment called melanin. Hair follicles, sebaceous (oil) glands, es the rate of melanin production and results in a and sudoriferous (sweat) glands are also located suntan. Differences in skin color are attributed to the It is composed primarily of loose connective tissue amount of melanin in each cell. Dark-skinned and adipose (fat) tissue interlaced with blood ves- people produce large amounts of melanin and are sels. The subcutaneous layer stores fats, insulates less likely to have wrinkles or skin cancer. Sebaceous glands are present over the Accessory Organs of the Skin entire body except on the soles of the feet and the The accessory organs of the skin consist of integu- palms of the hands. The glands play an on the scalp and face; around such openings as the important role in defending the body against dis- nose, mouth, external ear, and anus; and on the ease and maintaining homeostasis, whereas the upper back and scrotum. Hair Glands Hair is found on nearly all parts of the body except Two important glands located in the dermis pro- for the lips, nipples, palms of the hands, soles of duce secretions: the (6) sudoriferous (sweat) the feet, and parts of the external genitalia. The glands produce sweat and the (7) sebaceous (oil) visible part of the hair is the (8) hair shaft; the part glands produce oil.

A mild form of ichthyosis, called winter itch, is commonly seen on the legs of older patients, especially during the winter months. Xenografts are used as a temporary graft to protect the patient against infection and fluid loss. Cutaneous warts and actinic keratosis are common skin disorders that respond well to cryotherapy treatment.

This information helps determine how soon the patient will be able to return to normal activities after prostatectomy. Preoperative Nursing Diagnoses 251 Anxiety about surgery and its outcome Acute pain related to bladder distention Deficient knowledge about factors related to the disorder and the treatment protocol Postoperative Nursing Diagnoses Acute pain related to the surgical incision, catheter placement, and bladder spasms Deficient knowledge about postoperative care and management Collaborative Problems/Potential Complications Based on the assessment data, the potential complications may include the following: Hemorrhage and shock Infection Deep vein thrombosis Catheter obstruction Sexual dysfunction Planning and Goals The major preoperative goals for the patient may include reduced anxiety and learning about his prostate disorder and the perioperative experience. The major postoperative goals may include maintenance of fluid volume balance, relief of pain and discomfort, ability to perform self-care activities, and absence of complications. Preoperative Nursing Interventions Reducing Anxiety The patient is frequently admitted to the hospital on the morning of surgery. Because contact with the patient may be limited before surgery, the nurse must establish communication with the patient to assess his understanding of the diagnosis and of the planned surgical procedure. The nurse clarifies the nature of the surgery and expected postoperative outcomes. In addition, the nurse familiarizes the patient with the preoperative and postoperative routines and initiates measures to reduce anxiety. Because the patient may be sensitive and embarrassed discussing problems related to the genitalia and sexuality, the nurse provides privacy and establishes a trusting and professional relationship. Guilt feelings often surface if the patient falsely assumes a cause-and-effect relationship between sexual practices and his current problems. Relieving Discomfort If the patient experiences discomfort before surgery, he is prescribed bed rest, analgesic agents are administered, and measures are initiated to relieve anxiety. If he is hospitalized, the nurse monitors his voiding patterns, watches for bladder distention, and assists with catheterization if indicated. An indwelling catheter is inserted if the patient has continuing urinary retention or if laboratory test results indicate azotemia (accumulation of nitrogenous waste products in the blood). The catheter can help decompress the bladder gradually over several days, especially if the patient is elderly and hypertensive and has diminished renal function or urinary retention that has existed for many weeks. For a few days after the bladder begins draining, the blood pressure may fluctuate and renal function may decline. If the patient cannot tolerate a urinary catheter, he is prepared for a cystostomy (see 252 Chapters 44 and 45). Providing Instruction Before surgery, the nurse reviews with the patient the anatomy of the affected structures and their function in relation to the urinary and reproductive systems, using diagrams and other teaching aids if indicated. The nurse explains what will take place as the patient is prepared for diagnostic tests and then for surgery (depending on the type of prostatectomy planned). The nurse also describes the type of incision, which varies with the surgical approach (directly over the bladder, low on the abdomen, or in the perineal area; in the case of a transurethral procedure, no incision will be made), and informs the patient about the likely type of urinary drainage system, the type of anesthesia, and the recovery room procedure. The nurse explains procedures expected to occur during the immediate perioperative period, answers questions the patient or family may have, and provides emotional support.

Ischemic stroke is caused by a causes signs and symptoms in other parts of the narrowing of the arteries of the brain or the arter- body. Common signs and symptoms for many neu- ies of the neck (carotid), generally due to athero- rological disorders include headache, insomnia, back sclerosis.
