🔷 Liver disease can cause severe itching because bile products may build up in the skin.

🔷 Scratching can break the skin and lead to excoriation, bleeding, and infection.

🔷 Keeping the nails short reduces the amount of skin trauma caused by scratching.

🔷 Wearing soft cotton gloves at night protects the skin when the client scratches unknowingly during sleep.

🔷 The nurse should also encourage cool baths, mild soap, loose cotton clothing, and moisturizers to reduce irritation.

❌ Bathe frequently using deodorant soap

❌ Deodorant soap can dry and irritate the skin.

❌ Frequent bathing can remove natural skin oils and worsen itching.

❌ Apply hot compresses

❌ Heat can increase skin irritation and worsen pruritus.

❌ Cool compresses are usually more soothing.

❌ Apply topical alcohol

❌ Alcohol dries the skin and can cause burning or irritation.

❌ It can worsen itching and increase skin breakdown.

💎 In autoimmune disorders, the immune system mistakenly identifies normal body tissues as foreign and attacks them.

💎 This inappropriate immune response causes chronic inflammation, tissue destruction, and organ dysfunction over time.

💎 Examples include rheumatoid arthritis, systemic lupus erythematosus, and type 1 diabetes mellitus.

💎 Autoimmune diseases may affect a single organ or multiple body systems.

💎 Management often includes immunosuppressive therapy to reduce the abnormal immune response.

❌ Hypersensitivity

❌ Hypersensitivity refers to exaggerated immune reactions to allergens or foreign substances, not direct self-tissue destruction as seen in autoimmune disease.

❌ Secondary immune deficiency

❌ Secondary immune deficiencies occur because of external factors such as HIV infection, chemotherapy, or malnutrition, leading to weakened immunity.

❌ Primary immune deficiency

❌ Primary immune deficiencies are congenital disorders where parts of the immune system are absent or defective from birth.

🔷 MRI machines use powerful magnetic fields that can interact with metal-containing transdermal medication patches.

🔷 Some patches contain metallic backing that may heat during the scan and cause serious skin burns.

🔷 Safety screening before MRI is the priority because MRI-related injuries can occur if metallic objects remain on the body.

🔷 The nurse should also assess for implanted devices, jewelry, hearing aids, and other metallic items.

🔷 Preventing harm is the nurse’s first responsibility before diagnostic testing.

❌ Provide a blanket for comfort

❌ Comfort measures are important but are not the priority over ensuring MRI safety.

❌ Instruct the client to remain still during the scan

❌ Remaining still improves image quality, but safety screening takes priority before the procedure begins.

❌ Verify the client has been NPO for 8 hours

❌ Most routine MRI procedures do not require NPO status unless contrast or sedation is planned.

⚡ Foot and ankle exercises stimulate the calf muscles, which promotes venous return back to the heart.

⚡ Increased circulation reduces venous stasis, which is a major contributor to deep vein thrombosis formation.

⚡ Patients after orthopedic surgery are at especially high risk for DVT because of decreased mobility and vessel injury.

⚡ Active range-of-motion exercises are simple, effective, and commonly recommended after surgery.

⚡ These exercises also improve circulation without placing excessive stress on the surgical site.

❌ Apply ice packs to the affected limb to reduce inflammation

❌ Ice may decrease swelling and discomfort but does not effectively prevent venous stasis or DVT formation.

❌ Limit fluid intake to prevent fluid overload and swelling

❌ Dehydration increases blood viscosity and can actually raise the risk of clot formation.

❌ Maintain strict bed rest to avoid stress on the surgical site

❌ Prolonged immobility significantly increases the risk for DVT and pulmonary embolism.

🌟 Exploring successful coping strategies helps the patient recognize personal strengths previously used during stressful situations.

🌟 Support groups provide emotional encouragement, shared experiences, and practical advice from individuals facing similar challenges.

🌟 This approach promotes adaptation, acceptance, and emotional adjustment to lifestyle changes caused by mobility impairment.

🌟 Encouraging open discussion of frustrations helps validate the patient’s feelings and improves therapeutic communication.

🌟 Psychosocial support is essential for maintaining self-esteem and promoting independence during rehabilitation.

❌ Minimize discussion of the patient's feelings to promote positivity.

❌ Ignoring or minimizing feelings can make the patient feel unheard and may worsen emotional distress.

❌ Discuss reasons for device use only with family members.

❌ The patient should be actively involved in discussions and decision-making regarding their own care and mobility needs.

❌ Encourage the patient to avoid using the device in public settings.

❌ Avoiding assistive devices may increase fall risk and reduce mobility confidence rather than promote adaptation.

🔷 Hypertension occurs as the body attempts to maintain cerebral perfusion pressure when intracranial pressure rises.

🔷 Bradycardia develops because pressure on the brainstem affects cardiovascular control centers.

🔷 Irregular respirations indicate worsening brainstem compression and are a late, serious sign of increased ICP.

🔷 In bacterial meningitis, inflammation and cerebral edema can increase ICP rapidly, making Cushing’s triad an emergency finding.

🔷 This triad signals possible brain herniation risk and requires immediate provider notification and urgent intervention.

❌ Fever, neck stiffness, and photophobia

❌ These are classic findings of meningitis, but they do not make up Cushing’s triad.

❌ Hypotension, tachycardia, and rapid respirations

❌ This pattern is more consistent with shock or systemic infection, not Cushing’s triad.

❌ Tachycardia, hypertension, and shallow respirations

❌ Cushing’s triad includes bradycardia, not tachycardia.

💎 HIV can be transmitted through blood, semen, vaginal fluids, rectal fluids, and breast milk.

💎 Mother-to-child transmission can occur during pregnancy, childbirth, or breastfeeding.

💎 Antiretroviral therapy greatly reduces the risk of perinatal HIV transmission when started and maintained appropriately.

💎 Nurses should teach that HIV is not spread through casual daily contact.

💎 Prevention focuses on safe sex practices, avoiding blood exposure, and appropriate treatment during pregnancy.

❌ HIV can be transmitted through airborne droplets when a person coughs.

❌ HIV is not airborne and cannot be spread by coughing or sneezing.

❌ HIV can be spread through casual contact such as hugging or sharing utensils.

❌ HIV does not spread through hugging, touching, saliva, or shared eating utensils.

❌ HIV can be spread by mosquito bites.

❌ Mosquitoes do not transmit HIV because the virus does not survive or reproduce inside insects.

🔴 Herpes simplex encephalitis (HSE) is a life-threatening viral infection that causes inflammation and swelling of the brain tissue.

🔴 Classic findings include fever, altered mental status, headache, confusion, seizures, and neurologic changes.

🔴 IV acyclovir is the antiviral medication used to rapidly suppress herpes simplex virus replication and limit brain damage.

🔴 Treatment must begin immediately when HSE is suspected because delays can lead to permanent neurologic deficits, coma, or death.

🔴 Early administration of acyclovir significantly improves survival and neurologic outcomes in affected clients.

❌ Administer IV ceftriaxone and vancomycin

❌ These antibiotics are commonly used empirically for suspected bacterial meningitis, not herpes simplex encephalitis.

❌ Although bacterial meningitis may initially be considered in the differential diagnosis, antiviral therapy is the priority once HSE is suspected.

❌ Initiate droplet precautions

❌ Herpes simplex encephalitis is not spread through airborne droplets like meningococcal meningitis.

❌ Standard precautions are generally sufficient unless another contagious infection is suspected.

❌ Administer stat IV dexamethasone

❌ Dexamethasone may be used to reduce inflammation in some cases of bacterial meningitis, but it is not the priority treatment for HSV encephalitis.

❌ The key life-saving intervention is immediate antiviral therapy.

³

🔵 Stage 4 HIV (AIDS) is diagnosed when the CD4 count falls below 200 cells/mm³ or when the client develops an AIDS-defining opportunistic infection.

🔵 CD4 T-helper cells are essential for coordinating the body’s immune response against infections and diseases.

🔵 A CD4 count of 180 cells/mm³ indicates severe immune suppression and a greatly increased risk for opportunistic infections such as Pneumocystis jirovecii pneumonia, candidiasis, and tuberculosis.

🔵 Clients with AIDS require strict adherence to antiretroviral therapy (ART) and close monitoring for infection prevention and complications.

🔵 Early recognition of declining CD4 counts helps guide treatment decisions and improve long-term outcomes.

❌ CD4 count of 500 cells/mm³

❌ A CD4 count of 500 cells/mm³ is lower than normal but does not indicate progression to AIDS.

❌ Many clients with controlled HIV infection may maintain CD4 levels around this range with proper treatment.

❌ CD4 count of 350 cells/mm³

❌ This finding indicates moderate immune suppression but is still above the AIDS-defining threshold of 200 cells/mm³.

❌ The client remains at risk for infection but has not progressed to stage 4 HIV.

❌ CD4 count of 750 cells/mm³

❌ A CD4 count of 750 cells/mm³ is within or close to the normal immune function range.

❌ This finding does not indicate severe immune compromise or AIDS progression.

🟣 Swelling, warmth, purulent drainage, and fever are classic signs of a postoperative surgical site infection.

🟣 Purulent drainage strongly suggests the presence of bacterial infection, which may extend deeper into surrounding tissues and bone, leading to osteomyelitis.

🟣 Osteomyelitis is a serious bone infection that can rapidly progress and cause tissue destruction, sepsis, or impaired healing if not treated promptly.

🟣 Elevated temperature indicates a systemic inflammatory response and increases the urgency for immediate intervention.

🟣 The nurse should promptly notify the provider, monitor vital signs closely, anticipate wound cultures, and prepare for antibiotic therapy and further evaluation.

❌ Pressure injury

❌ Pressure injuries develop from prolonged pressure over bony prominences and usually present with skin breakdown rather than purulent surgical drainage.

❌ Fever and infected drainage are not typical early findings of a pressure injury.

❌ Osteoarthritis

❌ Osteoarthritis is a chronic degenerative joint disorder associated with cartilage wear and joint stiffness.

❌ It does not present suddenly with fever, drainage, and signs of acute infection after surgery.

❌ Deep vein thrombosis

❌ DVT may cause swelling, warmth, redness, and pain in the affected extremity.

❌ However, purulent drainage from the surgical site is more consistent with infection than thrombosis.
