An isotonic (5%) solution of glucose is used in these cir- plasma urea levels and can produce deterioration of renal func- cumstances, as the glucose is rapidly metabolized to carbon tion and increased loss of sodium in the urine.

The wound margins and the tissues within the base of the wound are usually blackened by smoke and may show signs of burning owing to the effect of flame cheap 10 ml astelin otc. Because the gases from the discharge are forced into the wound cheap astelin 10 ml visa, there may be subsid- iary lacerations at the wound margin, giving it a stellate-like shape. This is seen particularly where the muzzle contact against the skin is tight and the skin is closely applied to underlying bone, such as in the scalp. Carbon mon- oxide contained within the gases may cause the surrounding skin and soft 146 Payne-James et al. Con- tact wounds to the head are particularly severe, usually with bursting ruptures of the scalp and face, multiple explosive fractures of the skull, and extrusion or partial extrusion of the underlying brain. Most contact wounds of the head are suicidal in nature, with the temple, mouth, and underchin being the sites of election. In these types of wounds, which are usually rapidly fatal, fragments of scalp, skull, and brain tissue may be dispersed over a wide area. At close, noncontact range with the muzzle up to about 15 cm (6 in) from the skin, the entrance wound is still usually a single circular or oval hole with possible burning and blackening of its margins from flame, smoke, and unburned powder. Blackening resulting from smoke is rarely seen beyond approx 20 cm; tattooing from powder usually only extends to approx 1 m. Up to approx 1 m they are still traveling as a compact mass, but between approx 1–3 m, the pellets start to scatter and cause variable numbers of individual satellite punc- ture wounds surrounding a larger central hole. At ranges greater than 8–10 m, there is no large central hole, only multiple small puncture wounds, giving the skin a peppered appearance. Exit wounds are unusual with shotgun injuries because the shot is usu- ally dispersed in the tissues. However, the pellets may penetrate the neck or a limb and, in close-range wounds to the head, the whole cranium may be dis- rupted. Rifled Weapon Wounds Intact bullets penetrating the skin orthogonally, that is, nose-on, usually cause neat round holes approx 3–10 mm in diameter. Close examination reveals that the wound margin is usually fairly smooth and regular and bordered by an even zone of creamy pink or pinkish red abrasion. A nonorthogonal nose-on strike is associated with an eccentric abrasion collar, widest at the side of the wound from which the bullet was directed (see Fig. Atypical entrance wounds are a feature of contact or near contact wounds to the head where the thick bone subjacent to the skin resists the entry of gases, which accumu- late beneath the skin and cause subsidiary lacerations to the wound margins, imparting a stellate lacerated appearance. Contact wounds elsewhere may be bordered by the imprint of the muzzle and the abraded margin possibly charred and parchmented by flame. Punctate discharge abrasion and sooty soiling are usually absent from the skin surface, but the subcutaneous tissues within the depth of the wound are usually soiled. The effects of flame are rarely seen beyond 10 cm (4 in), with sooty soiling extending to approx 20 cm (8 in). Punctate discharge abrasions, which may be particularly heavy with old revolver ammunition, are often present at ranges up to approx 50 cm (20 in). It is impor- tant to remember that sooty soiling of the skin surrounding a wound is easily removed by vigorous cleaning carried out by medical or nursing staff. The soiling of contact close-range entrance wounds may be absent if clothing or other material is interposed between the skin surface and the muzzle of the weapon. Bullet exit wounds tend to be larger than entrance wounds and usually consist of irregular lacerations or lacerated holes with everted, unabraded, and unbruised margins. When the skin at the site of an entrance wound has been supported by tight clothing, eversion of the margins of the wound may be absent and the margins may even be abraded, albeit somewhat irregularly, but nevertheless making differentiation from entrance wounds more difficult. Entrance wounds caused by damaged or fragmented bullets may be so atypical that it may not be possible to offer a useful opinion as to their nature. It is inappropriate to offer an opinion on the caliber of a bullet based on the size of an entrance wound, and it is not possible to state whether the bullet was fired from a revolver, pistol, or rifle by only the appearance of the wound. These inju- ries typically are seen when an individual has tried to defend himself or herself against an attack and are the result of instinctive reactions to assault. When attacked with blunt objects, most individuals will attempt to protect their eyes, head, and neck by raising their arms, flexing their elbows, and covering their head and neck. Thus, the extensor surface of the forearms (the ulnar side), the lateral/ posterior aspects of the upper arm, and the dorsum of the hands may receive blows. Similarly, the outer and posterior aspects of lower limbs and back may be injured when an individual curls into a ball, with flexion of spine, knees, and hips to protect the anterior part of the body. In sharp-blade attacks, the natural reaction is to try and disarm the attacker, often by grabbing the knife blade. Occasionally, the hands or arms may be raised to protect the body against the stabbing motion, resulting in stab wounds to the defense areas. In blunt-force attacks, the injuries sustained usually take the form of bruises if the victim is being punched or kicked, but there may also be abra- sions and/or lacerations depending on the nature of the weapon used. If the victim is lying on the ground while being assaulted, he or she will tend to curl up into a fetal position to protect the face and the front of the trunk, particu- larly from kicks. In these circumstances, defensive bruising is likely to be seen on other surfaces of the trunk and limbs.

If client is unable or unwilling to speak (mutism) generic astelin 10 ml without prescription, use of the technique of verbalizing the implied is therapeutic cheap 10 ml astelin visa. Anticipate and fulfill client’s needs until satisfactory com- munication patterns return. Client is able to recognize that disorganized thinking and impaired verbal communication occur at times of increased anxiety and intervene to interrupt the process. Show client, on concrete level, how to perform activities with which he or she is having difficulty. Client may be unable to tolerate large amounts of food at mealtimes and may therefore require additional nourishment at other times during the day to receive adequate nutrition. If client is not eating because of suspiciousness and fears of being poisoned, provide canned foods and allow client to open them; or, if possible, suggest that food be served family- style so that client may see everyone eating from the same servings. Assist client to bathroom on hourly or bi-hourly schedule, as need is determined, until he or she is able to fulfill this need without assistance. Client selects appropriate clothing, dresses, and grooms self daily without assistance. Client maintains optimal level of personal hygiene by bathing daily and carrying out essential toileting procedures without assistance. Possible Etiologies (“related to”) [Panic level of anxiety] [Repressed fears] [Hallucinations] [Delusional thinking] Defining Characteristics (“evidenced by”) [Difficulty falling asleep] [Awakening very early in the morning] [Pacing; other signs of increasing irritability caused by lack of sleep] [Frequent yawning, nodding off to sleep] Schizophrenia and Other Psychotic Disorders ● 123 Goals/Objectives Short-term Goal Within first week of treatment, client will fall asleep within 30 minutes of retiring and sleep 5 hours without awakening, with use of sedative if needed. Long-term Goal By time of discharge from treatment, client will be able to fall asleep within 30 minutes of retiring and sleep 6 to 8 hours with- out a sleeping aid. Accurate baseline data are important in planning care to assist client with this problem. Administer antipsychotic medication at bedtime so client does not become drowsy during the day. Assist with measures that promote sleep, such as warm, non- stimulating drinks; light snacks; warm baths; and back rubs. Major Depressive Disorder Major depressive disorder is described as a disturbance of mood involving depression or loss of interest or pleasure in the usual activities and pastimes. There is evidence of interference in social and occupational functioning for at least 2 weeks. There is no history of manic behavior and the symptoms cannot be attributed to use of substances or a general medical condition. The following specifiers may be used to further describe the depressive episode: 1. Single Episode or Recurrent: This specifier identifies whether the individual has experienced prior episodes of depression. Mild, Moderate, or Severe: These categories are identified by the number and severity of symptoms. With Catatonic Features: This category identifies the presence of psychomotor disturbances, such as severe psycho- motor retardation, with or without the presence of waxy flex- ibility or stupor or excessive motor activity. The client also may manifest symptoms of negativism, mutism, echolalia, or echopraxia. With Melancholic Features: This is a typically severe form of major depressive episode. There is a history of major depressive episodes that have responded well to somatic anti- depressant therapy. Chronic: This classification applies when the current episode of depressed mood has been evident continuously for at least the past 2 years. With Seasonal Pattern: This diagnosis indicates the pres- ence of depressive symptoms during the fall or winter months. With Postpartum Onset: This specifier is used when symp- toms of major depression occur within 4 weeks postpartum. Dysthymic Disorder Dysthymic disorder is a mood disturbance with character- istics similar to, if somewhat milder than, those ascribed to major depressive disorder. Substance-Induced Depressed Mood Disorder The depressed mood associated with this disorder is considered to be the direct result of the physiological effects of a substance (e. Genetic: Numerous studies have been conducted that sup- port the involvement of heredity in depressive illness. Biochemical: A biochemical theory implicates the bio genic amines norepinephrine, dopamine, and serotonin. The levels of these chemicals have been found to be defi- cient in individuals with depressive illness. Neuroendocrine Disturbances: Elevated levels of serum cortisol and decreased levels of thyroid-stimulating Mood Disorders: Depression ● 127 hormone have been associated with depressed mood in some individuals. Medication Side Effects: A number of drugs can produce a depressive syndrome as a side effect. Antihypertensive medications such as propranolol and re- serpine have been known to produce depressive symptoms.
