Pain Ep igastric pain relieved by eating food Burning in the chest Nausea and vomiting (hematemesis) Worse with activities that increase intra-abdominal pressure Diarrhea Anorexia Worse 30 – 60 minutes after eating. Intestinal gas Cholinergics, such as bethanechol (Urecholine), increase lower esophageal sphincter pressure and promote gastric emptying. Dopami ne antagonists, such as metoclopramide (Reglan), move food through the gastrointestinal system faster. Antaci ds, such as aluminum and magnesium (Maalo x), neutralize stomach acid. Histami ne (H2 )-receptor antagonists, such as ranitidine (Zantac), block acid production. Proton pump inhi bitors, such as lansoprazole (Prevacid), shut down the acid pump in the stomach. Aci d-protecti ve agents, such as sucralfate (Carafate), provide a thick protective coat over the lower esophagus and stomach. Avoid irritating substances (NSAIDs, alcohol) Avoid foods which decrease pressure on lower esophagus (chocolate, fatty foods, onion, garlic, peppermint, spearmint, tea and coffee). Avoid medicat ions which relax the lower esophagus (anticholinergics, beta-blockers, calciu m channel blockers, diazepam, morphine sulfate, n icotine, nitrates, progesterone, estrogen and theophylline) Eat s mall meals Elevate HOB on 6 – 8” b locks Encourage weight loss and smoking cessation Treat ment Discharge Gastritis instructions Ulcers Duodenal ulcers Gastric ulcers •Common between the ages of 30 and 55 •Pain starts prior to meals and is relieved by food or antacids •Common between the ages of 55 and 70. •Pain usually occurs after eating Regardless of site of ulcer, typical pain is described as “squeezing”, “indigestion”, “gnawing”, “colicky”, “aching” or “feeling of fullness” that is often epigastric and may radiate through to the mid back Definiti on: Disorders of organs of the bile duct (liver, gall b ladder, pancreas) Murphy’s sign – Cholecystits inability of the patient Signs and symptoms to inhale deeply during palpation under the Pain right costal margin RUQ tenderness, guarding and rigid ity, aggravated by taking a deep breath near the liver Typically follows ingestion of fried ro fatty foods or ingesion of a large meal.

Sexually Transmitted Diseases o Genital Herpes (This chronic, incurable sexually transmitted disease is caused by the herpes simplex virus type 2) o First symptoms are flu-like sympto ms immed iately after exposure to the virus followed by stinging and burning around the genetalia than eruption of blisters in the area of the pain. The symptoms will usually resolve in after several weeks, but may recur 3 to 4 t imes per year, especially in times of stress or with local trauma to the genital area. There is no cure. Treat ment: antiviral medicat ions, warm baths, topical anesthetics, analgesics Gonorrhea and Chlamyd ia Sympto ms: A thick yellow or white d ischarge fro m the genitalia 2 – 7 days after exposure. Other symptoms such as abnormal vaginal bleeding, vaginal itching, and dysuria sometimes occur. Women may also develop pelvic inflammatory disease. Treat ment: Antibiotics • • • • • • • Discharge teaching for genital herpes Use barrier protection during intercourse and avoid intercourse during periods of outbreak. Intercourse should not be resumed until the lesions have crusted over. Women with this virus have an increased risk of cervical cancer and should be routinely monitored with pap smears. Keep lesions clean and dry Avoid using lubricants and creams wh ich can increase healing time Wear loose clothing and cotton underwear to decrease pressure and irritation Use drying agents such as Campho-Phenique Use soaks, sitz baths and cool compresses for local pain relief Chlamyd ia is a primary cause of infertility in females and nongonococcal urethritis in heterosexual males. Chlamydia has also been linked to preterm labor and postpartum endometriosis. 10 | P a g e Certified Emergency Nurse (CEN) Exam Review Jeff Solheim Testicular disorders Testicular torsion Definition Co mmon age of onset Onset of pain Quality of pain Precip itating factors Sympto ms other than pain Treat ment Twisting of the testicle on the spermatic cord causing testicular hypoxia. 66% occurs between the ages of 12 and 18 when maximal hormone stimulat ion is present although it may occur at any age. Rapid onset of pain as soon as torsion occurs Usually described as a severe pain in the lower abdomen and inguinal canal. 50% are init iated during sleep, but exertion such as heavy lift ing or sporting activities as well as testicular trau ma may also precip itate the condition. Elevation or man ipulation of the scrotum may increase the pain Nausea, vomit ing, lo w grade fever, scrotal enlargement, redness, pallor, elevated testicle on the affected side with the epididymis ly ing anterior secondary to twisting of the testicle. The affected testicle may also be firm and tender to palpation. Lack of cremasteric reflex. Testicular detorsion may be attempted under sedation in the emergency department through the scrotal sac or in the surgical suite under anesthesia. Detorsion should be performed as quickly as possible. If performed within six hours, the testicular salvage rate is as high as 80 – 100%, but after 12 hours, orchiecto my will likely be required. Orchit is (inflammation of the testicle) o Sympto ms Testicular pain and swelling Hematuria Ejaculation of blood o Treat ment NSAIDs Steroids Elevation of scrotum on an ice pack Phimosis/Paraphimosis Definiti on: Phi mosis A condition where the foreskin does not fully retract over the head of the penis Ep ididy mit is Infection of the epididy mitis, In younger males the infection is usually secondary to a sexually transmitted infection such as Chlamydia trachomatis and in older males, it is more likely to be caused by bacteria such as E. Coli secondary to underlying obstructive urinary disease. Because this condition is secondary to either sexually transmitted infections or obstructive urinary disease, it is more co mmonly found in males over the age of 20. Gradual onset of pain as infection worsens. Dull ache in the lower abdomen and scrotum. Elevation of the scrotum and wearing supportive garments may dimin ish the pain. Sexual activity may exacerbate the pain. In so me cases, the cause may be ext reme physical strain or exert ion. Urinary frequency, urgency or dysuria, nausea, fever, chills, urethral d ischarge, “duck waddle” gait, edematous and erythematous epididymit is and scrotum, scrotal warmth and tenderness, pyuria, and elevated white blood cell count Admin istration of antibiotics, antipyretics, and analgesics. Discharge instructions include bed rest for 3 – 4 days. When they are out of bed, scrotal support should be worn. Sexual activity and physical strain should be avoided until the infection has cleared. Indications of worsening infection (sustained fever, increasing abdominal pain, o r continued dysuria) should result in fo llo w-up with a med ical p rovider. Because the causative agent is often a sexually transmitted disease, safe sexual p ractices as well as follow up for sexual partners should be encouraged. Mumps and untreated or undertreated epididymit is are frequent causes of orchitis Definiti on: Paraphi mosis Forceful retract ion of the foreskin over the head of the penis creating a tight band that can obstruct urinary flo w and create ischemia to the penile head. Treat ment involves application of ice to reduce swelling for manual reduction. If this is unsuccessful, surgery may be needed. 11 | P a g e Certified Emergency Nurse (CEN) Exam Review o o Vaginal pH Discharge Normal vaginal discharge 3.8 White, clear Odor Main patient complaint Absent None Treat ment None • Jeff Solheim Fractured penis (Rupture of the tunica albuginea surrounding the corpora cavernosa causing blood to extravasate into the penile shaft.) o Patient may co mplain of hearing a “popping noise during sexual intercourse or sexual p lay followed by severe pain, swelling and discoloration of the penis. o Treat ment Ice to reduce swelling Analgesia Catheterization if no urethral damage suspected.

Emergency Delivery Place the wo man in the dorsal recu mbent position with her knees bent or the side -lying position with her knees bent and raise the buttocks slightly on an object. If t ime permits, cleanse the perineum with soap and water or pour antiseptic solution over the perineal area. To reduce the risk of infect ion, be as sterile as the situation allows. Drape the perineal area with sterile towels and keep fingers out of the vagina. Every effort should be made to decrease a rapid, explosive delivery which can tear the perineu m. Encourage the mother to pant while the head is being delivered to reduce the urge to bear down. As the head is delivered, place gentle pressure to prevent explosive delivery. If the memb ranes are still intact over t he head, snip them at the nape of the neck and pull them away fro m the infant’s face. Feel fo r the presence of a cord around the neck. If this is felt, attempt to slip the cord over the infants head between contractions. If this is not possible, immedia tely clamp the cord in two places and cut the cord between the clamps. To deliver the shoulders, place the palms of the hands on either side of the infant’s head and gently direct it down ward to deliver the anterior shoulder and then upward to assist with delivery of the posterior shoulder. Once the cord stops pulsating, place one clamp 4 – 5 centimeters fro m the infant’s abdomen and another clamp approximately 4 – 5 centimeters toward the mother and cut the cord between the two clamps using a sterile scissors or scalpel. If sterile equip ment is not available, it is not necessary to cut the umbilicus, keep the infant at or belo w the le vel of the mother until the cord is cut. Post-delivery infant care Place head in sniffing position and suction mouth an d then nose Measure Apgar scores at 1,5 and 10 minutes Dry the in fant Cover the infants head Place on the mother’s chest and encourage breast-feeding to stimulate oxytocin Cover with dry blan kets Palpate fundus q 5 minutes after delivery of placenta Massage boggy uterus until firm.
