A patient presents to an eye clinic with a number of symptoms related to his diminished vision. An initial history leads the nurse practitioner to suspect that the patient has acute angle-closure glaucoma. Which of the following symptoms would apply to this diagnosis? Select all that apply.

- Severe eye pain - Reddening of the eye - Sudden onset of visual disturbance - Nausea and vomiting

Mixed UI

- both urgency and stress incontinence - 32% of pts with UI - more common in women

urge ui and benign prostatic hypertrophy (BPH)

- bph should be treated first - if still symptomatic, use antimuscarinic therapy as long as no urinary retention *bladder scan will help make sure there's no urinary retention

caution using antimuscarinics in these people

- caution in frail elderly, cognitive impairment, dementia, and parkinsons - caution with other drugs with safe effects - reevaluate often!

(diagnostic procedures) immunofluorescence

- detects antibodies on skin (direct) - detects antibodies in serum (indirect)

what are the layers of the skin?

- epidermis (top layer) - dermis (middle layer) - hypodermis or subcutaneous (bottom layer)

what are some skin appearances we might see?

- erythema (redness) - rash - cyanosis (blue color from lack of O2) - jaundice (yellow color, liver disease) - pruritus (itchiness of skin) can see these signs centrally or peripherally - peripheral = fingers & toes - central = mucous membranes, tongue

Urge UI - antimuscarinics

- first line - relax detrusor muscle - modest efficacy CI: urinary retention, angle glaucoma, gastric retention

Theoretical advantages of selective antimuscarinics in Urge UI

- increases selectivity for bladder muscarinic (M3) receptors - decreases lipophilicity which decreases BBB penetration - decreases adverse effects (cognitive impairment, dry mouth, constipation)

urinary incontinence (UI)

- involuntary loss of urine of sufficient volume to cause problems for pt - 1/10 pts - women>men

Urge UI

- leakage associated with a sudden, uncontrollable need to pee (void) - 14% of UI pts - overactive bladder/detrusor overactivity (urgency w/ or w/o actual incontinence) - increased daytime frequency and notcuria

Overflow UI

- leakage of urine from a full bladder - common with urinary retention - poor detrusor contractility or bladder outlet obstruction

what are some functions of the skin?

- protection (keratin) - sensation (CNS & ANS, touch, pain, pressure) - fluid balance (sweat, assess skin turgor) - temp regulation (convection, conduction, radiation, evaporation) - vitamin D synthesis (from the sun) - immune response (normal flora on skin) - absorption (medications) - elimination (sweat glands, sebaceous glands) - psychosocial (body image, tattoos, piercings)

pelvic floor muscle training

- recommended for everyone - first line for urge, stress, mixed UI - try for 6-12 weeks - be consistent to see results - kegal - if done properly, most effective

alpha antagonists in tx bph

- relax smooth muscle in bladder neck and prostate - selective blockade reduces hypotension SE: ha, dizziness, orthostatic hypotension

what are normal aging changes of the skin?

- thinning of skin - uneven pigmentation - increased fragility - reduced healing ability decreased collagen (protein), decreased skin turgor (will see tenting), and increase for skin tears & pressure ulcers

what are some integumentary infections?

- tine corpis (ringworm) - shingles (herpes zoster) - herpes simplex - varicella (chicken pox) - urticaria (allergic reaction) - contact dermatitis - erythema gyratum repens (EGR) (lupus) - steven-johnson syndrome (caused by medications) - psoriasis

meds that cause ui

1. alcohol 2. alpha agonists (pseudoephedrine) 3. alpha antagonists (terazosin) 4. anticholinergics 5. acetylcholinesterase (donepezil) 6. antispsychotics (typical) 7. CCBs 8.

Fluid restriction, supine positioning, and diuretics are not indicated.)

A major role for nursing in the management of glaucoma is health education. Which of the following is the most important teaching point that the nurse should advise the patient of?

Adhere to the medication regimen.

The nurse is educating a patient about performing testicular self-examination (TSE). The nurse informs the patient that the best time to perform the exam is when?

After a warm bath or shower

A client is undergoing diagnostics due to a significant drop in renal output. The physician has scheduled an angiography. What postprocedural assessment will the nurse perform on the client? a) Monitor hypersensitivity response. b) Palpate pedal pulses. c) All options are correct. d) Monitor site condition.

All options are correct. After the procedure, the physician applies a pressure dressing to the femoral area, which remains in place for several hours. The nurse palpates the pulses in the legs and feet at least every 1 to 2 hours for signs of arterial occlusion. Monitoring the pressure dressing is important to note frank bleeding or hematoma formation. If either condition occurs, the nurse immediately notifies the physician. Another important assessment is for hypersensitivity responses to contrast material. The client remains on bed rest for 4 to 8 hours. The nurse also monitors and documents intake and output.

Medical management of BPH includes pharmacologic therapy. Which of the following medications would the nurse expect the health care provider to prescribe for this diagnosis?

Alpha-adrenergic blocker

Nephrotoxicity can occur as a result of the use of aminoglycosides such as gentamicin. Select all of the following statements which are true. a) All statements are true. b Nephrotoxicity from the use of the aminoglycosides is reversible if the drug is discontinued as soon as the symptoms appear. c) Aminoglycosides can result in increased levels of BUN and serum creatinine, indicating nephrotoxicity. d) Signs of nephrotoxicity may not occur until the client has received 5 or more days of therapy.

Aminoglycosides can result in increased levels of BUN and serum creatinine, indicating nephrotoxicity. Signs of nephrotoxicity may not occur until the client has received 5 or more days of therapy. Nephrotoxicity from the use of the aminoglycosides is reversible if the drug is discontinued as soon as the symptoms appear. Aminoglycosides can result in increased levels of BUN and serum creatinine, indicating nephrotoxicity. Signs of nephrotoxicity may not occur until the client has received 5 or more days of therapy. Nephrotoxicity from the use of the aminoglycosides is reversible if the drug is discontinued as soon as the symptoms appear.

The nurse is caring for a patient who has been NPO for 2 days pending a diagnostic procedure that has been repeated cancelled. When evaluating this patient's urinalysis, what would the nurse anticipate? a) A fluctuating urine specific gravity b) A decreased urine specific gravity c) An increased urine specific gravity d) A fixed urine specific gravity

An increased urine specific gravity Urine specific gravity depends largely on hydration status. A decrease in fluid intake (such as a "nothing by mouth" status) will lead to an increase in the urine specific gravity. With high fluid intake, specific gravity decreases. In patients with kidney disease, urine specific gravity does not vary with fluid intake, and the patient's urine is said to have a fixed specific gravity.

Assessment of a patient's leg reveals the presence of a 1.5-cm circular region of necrotic tissue that is deeper than the epidermis. The nurse should document the presence of what type of skin lesion?A)Keloid B)Ulcer C)Fissure D)Erosion

An ulcer is skin loss extending past the epidermis with the involvement of necrotic tissue.

Which of the following diagnostic tests would the nurse expect to be ordered to determine the details of the arterial supply to the kidneys? a) Cystoscopy b) Radiography c) Computed tomography (CT scan) d) Angiography

Angiography Angiography provides the details of the arterial supply to the kidneys, specifically the number and location of renal arteries. Radiography shows the size and position of the kidneys, ureters, and bladder. A CT scan is useful in identifying calculi, congenital abnormalities, obstruction, infections, and polycystic diseases. Cystoscopy is used for providing a visual examination of the internal bladder.

In Fabry disease, most male patients and 30% of female heterozygotes will have what?

Angiokeratomas Small, dark spots appear on the skin. In Fabry usually concentrated between the umbilicus and knees.

The nurse in an ambulatory care center is admitting an older adult patient who has bright red moles on the skin. Benign changes in elderly skin that appear as bright red moles are termed what?A) Cherry angiomas B) Solar lentigo C) Seborrheickeratoses D) Xanthelasma

Ans: A Feedback: Cherry angiomas appear as bright red moles, while solar lentigo are commonly called liver spots. Seborrheickeratoses are described as crusty brown stuck on patches, while xanthelasma appears as yellowish, waxy deposits on the upper eyelids.

A gerontologic nurse is teaching a group of nursing students about integumentary changes that occur in older adults. How should these students best integrate these changes into care planning? A) By avoiding the use of moisturizing lotions on older adults' skin B)By protecting older adults against shearing injuries C)By avoiding the use of ice packs to treat muscle pain D)By protecting older adults against excessive sweat accumulation

Ans: B Feedback: Cellular changes associated with aging include thinning at the junction of the dermis and epidermis, which creates a risk for shearing injuries. Moisturizing lotions can be safely used to address the increased dryness of older adults' skin. Ice packs can be used, provided skin is assessed regularly and the patient possesses normal sensation. Older adults perspire much less than younger adults, thus sweat accumulation is rarely an issue.

A patient is diagnosed with atrial fibrillation and the physician orders Coumadin (warfarin). For what skin lesion should the nurse monitor this patient? A) Ulcer B)Ecchymosis C)Scar D)Erosion

Ans: B Feedback: Ecchymosis refers to a round or irregular macular lesion, which is larger than petechiae. This occurs secondary to blood extravasation. It is important to watch for ecchymosis in a patient receiving any type of anticoagulant. An ulcer is an open lesion eroded into the patient's flesh. A scar is an area on the skin caused by the healing of an injury. Erosion is loss of superficial epidermis that does not extend to the dermisa depressed, moist area.

student is brought to the nurse after falling off a swing. nurse is documenting that the child has bruising on the lateral aspect of the right arm. What term will the nurse use to describe bruising on the skin in documentation? A) Telangiectasias B) Ecchymoses C) Purpura D) Urticaria

Ans: B Feedback: Telangiectasias consists of red marks on the skin caused by stretching of superficial blood vessels. Ecchymoses are bruises, and purpura consists of pinpoint hemorrhages into the skin. Urticariais wheals or hives.

Applies gentle pressure bilaterally on the bridge of the nose to the inner canthus of each eye

A nurse is doing a shift assessment on a group of patients after first taking report. An elderly patient is having her second dose of IV antibiotics for a diagnosis of pneumonia. The nurse notices a new rash on the patient's chest. The nurse should ask what priority question regarding the presence of a reddened rash? A) Is the rash worse at a particular time or season? B)Are you allergic to any foods or medication? C)Are you having any loss of sensation in that area? D)Is your rash painful?

Ans: B Feedback: The nurse should suspect an allergic reaction to the antibiotic therapy. Allergies can be a significant threat to the patient's immediate health, thus questions addressing this possibility would be prioritized over those addressing sensation. Asking about previous rashes is important, but this should likely be framed in the context of an allergy assessment.

The nurse is performing an initial assessment of a patient who has a raised, pruritic rash. The patient denies taking any prescription medication and denies any allergies. What would be an appropriate question A)Is anyone in your family allergic to anything? B)How long have you had this abrasion? C)Do you take any over-the-counter drugs or herbal preparations? D)What do you do for a living?

Ans: C Feedback: If suspicious areas are noted, the patient is questioned about nonprescription or herbal preparations that might be in use. Ascertaining a family history of allergies would not give helpful information at this time. The patient's lesion is not described as an abrasion. The patient's occupation may or may not be relevant; it is more important to assess for herb or drug reactions.

A new patient has come to the dermatology clinic to be assessed for a reddened rash on his abdomen. What diagnostic test would most likely be ordered to identify the causative allergen?A) Skin scrapings B)Skin biopsy C)Patch testing D) Tzanck smear

Ans: C Feedback: Patch testing is performed to identify substances to which the patient has developed an allergy. Skin scrapings are done for suspected fungal lesions. A skin biopsy is completed to rule out malignancy and to establish an exact diagnosis of skin lesions. A Tzanck smear is used to examine cells from blistering skin conditions, such as herpes zoster.

A new patient presents at the clinic and the nurse performs a comprehensive health assessment. The nurse notes that the patient's fingernail surfaces are pitted. The nurse should suspect the presence of what A) Eczema B) Systemic lupus erythematosus (SLE) C) Psoriasis D) Chronic obstructive pulmonary disease (COPD)

Ans: C Feedback: Pitted surface of the nails is a definite indication of psoriasis. Pitting of the nails does not indicate eczema, SLE, or COPD.

While assessing a 25-year-old female, nurse notes the patient has hair on her lower abdomen. Earlier in the health interview, the patient stated that her menses are irregular. nurse should suspect what type of health problem?A) A metabolic disorder B)A malignancy C)A hormonal imbalance D)An infectious process

Ans: C Feedback: Some women with higher levels of testosterone have hair in the areas generally thought of as masculine, such as the face, chest, and lower abdomen. This is often a normal genetic variation, but if it appears along with irregular menses and weight changes, it may indicate a hormonal imbalance. This combination of irregular menses and hair distribution is inconsistent with metabolic disorders, malignancy, or infection.

When planning the skin care of a patient with decreased mobility, the nurse is aware of the varying thickness of the epidermis. At what location is the epidermal layer thickest?A) The scalp B) The elbows C) The palms of the hands D) The knees

Ans: C, D Feedback: Gloves are worn during skin examination if a rash or lesions are to be palpated. It is not normally necessary to wear gloves to palpate a patient's scalp, extremities, or fingers unless contact with body fluids is reasonably foreseeable.

33. A nurse is assessing the skin of a patient who has been diagnosed with bacterial cellulitis on the dorsal portion of the great toe. When reviewing the patient's health history, the nurse should identify what comorbidity as increasing the patient's vulnerability to skin infections? A Chronic obstructive pulmonary disease B Rheumatoid arthritis C) Gout D)Diabetes

Ans: D Feedback: Patients with diabetes are particularly susceptible to skin infections. COPD, RA, and gout are less commonly associated with integumentary manifestations.

A patient with an exceptionally low body mass index has been admitted to the emergency department with signs and symptoms of hypothermia. The nurse should know that this patient's susceptibility A)Epidermis B)Merkel cells C)Dermis D)Subcutaneous tissue

Ans: D Feedback: The subcutaneous tissues and the amount of fat deposits are important factors in body temperature regulation. The epidermis is an outermost layer of stratified epithelial cells. Merkel cells are receptors that transmit stimuli to the axon through a chemical synapse. The dermis makes up the largest portion of the skin, providing strength and structure. It is composed of two layers: papillary and reticular.

An 82-year-old patient is being treated in the hospital for a sacral pressure ulcer. What age-related change is most likely to affect the patient's course of treatment? A) Increased thickness of the subcutaneous skin layer B) Increased vascular supply to superficial skin layers C) Changes in the character and quantity of bacterial skin flora D) Increased time required for wound healing

Ans: D Feedback: Wound healing becomes slower with age, requiring more time for older adults to recover from surgical and traumatic wounds. There are no changes in skin flora with increased age. Vascular supply and skin thickness both decrease with age.

A nurse is aware that the outer layer of the skin consists of dead cells that contain large amounts of keratin. The physiologic functions of keratin include which of the following? A)Producing antibodies B)Absorbing electrolytes C)Maintaining acidbase balance D)Physically repelling pathogens E)Preventing fluid loss

Ans: D, E Feedback: The dead cells of the epidermis contain large amounts of keratin, an insoluble, fibrous protein that forms the outer barrier of the skin. Keratin has the capacity to repel pathogens and prevent excessive fluid loss from the body. It does not contribute directly to antibody production, acidbase balance, or electrolyte levels.

A patient has undergone a renal biopsy. After the test, while the patient is resting, the patient complains of severe pain in the back, arms, and shoulders. Which of the following appropriate nursing interventions should be offered by the nurse? a) Asses the patient's back and shoulder areas for signs of internal bleeding. b) Distract the patient's attention from the pain. c) Provide analgesics to the patient. d) Enable the patient to sit up and ambulate.

Asses the patient's back and shoulder areas for signs of internal bleeding. After a renal biopsy, the patient is on bed rest. The nurse observes the urine for signs of hematuria. It is important to assess the dressing frequently for signs of bleeding, monitor vital signs, and evaluate the type and severity of pain. Severe pain in the back, shoulder, or abdomen may indicate bleeding. In such a case, the nurse should notify the physician about these signs and symptoms. The nurse should also assess the client for difficulty voiding and encourage adequate fluid intake. Distracting the patient's attention, helping the patient to sit up or ambulate, and providing analgesics may only aggravate the patient's pain and, therefore, should not be performed by the nurse.

After undergoing renal arteriogram, in which the left groin was accessed, a client complains of left calf pain. Which intervention should the nurse perform first? a) Exercise the leg and foot. b) Assess for anaphylaxis. c) Place cool compresses on the calf. d) Assess peripheral pulses in the left leg.

Assess peripheral pulses in the left leg. The nurse should begin by assessing peripheral pulses in the left leg to determine if blood flow was interrupted by the procedure. The client may also have thrombophlebitis. Cool compresses aren't used to relieve pain and inflammation in thrombophlebitis. The leg should remain straight after the procedure. Calf pain isn't a symptom of anaphylaxis.

Which of the following does the nurse recognize is the best clinical measure of renal function? a) Volume of urine output b) Creatinine clearance c) Urine-specific gravity d) Circulating ADH levels

Creatinine clearance Creatinine clearance is a good measure of the glomerular filtration rate (GFR), the amount of plasma filtered through the glomeruli per unit of time. Creatinine clearance is the best approximation of renal function. As renal function declines, both creatinine clearance and renal clearance (the ability to excrete solutes) decreases.

client develops decreased renal function and requires a change in antibiotic dosage. On which factor should the physician base the dosage change?

Creatinine clearance The physician should base changes to antibiotic dosages on creatinine clearance test results, which gauge the kidney's glomerular filtration rate; this factor is important because most drugs are excreted at least partially by the kidneys. The GI absorption rate, therapeutic index, and liver function studies don't help determine dosage change in a client with decreased renal function.

A patient is being seen in the clinic for possible kidney disease. What major sensitive indicator of kidney disease does the nurse anticipate the patient will be tested for? a) Creatinine clearance level b) Uric acid level c) Blood urea nitrogen level d) Serum potassium level

Creatinine clearance level Creatinine is an endogenous waste product of skeletal muscle that is filtered at the glomerulus, passed through the tubules with minimal change, and excreted in the urine. Hence, creatinine clearance is a good measure of the glomerular filtration rate (GFR), the amount of plasma filtered through the glomeruli per unit of time. Creatinine clearance is the best approximation of renal function. As renal function declines, both creatinine clearance and renal clearance (the ability to excrete solutes) decrease.

An appropriate nursing intervention for the client following a nuclear scan of the kidney is to: a) Apply moist heat to the flank area. b) Encourage high fluid intake. c) Strain all urine for 48 hours. d) Monitor for hematuria.

Encourage high fluid intake. A nuclear scan of the kidney involves the IV administration of a radioisotope. Fluid intake is encouraged to flush the urinary tract to promote excretion of the isotope. Monitoring for hematuria, applying heat, and straining urine do not address the potential renal complications associated with the radioisotope.

Following a voiding cystogram, the client has a nursing diagnosis of risk for infection related to the introduction of bacterial following manipulation of the urinary tract. An appropriate nursing intervention for the client is to: a) Encourage high fluid intake. b) Apply moist heat to the flank area. c) Monitor for hematuria. d) Strain all urine for 48 hours.

Encourage high fluid intake. A voiding cystogram involves the insertion of a urinary catheter, which can result in the introduction of microorganism into the urinary tract. Fluid intake is encouraged to flush the urinary tract and promote removal of microorganisms. Monitoring for hematuria, applying heat, and straining urine do not address the nursing diagnosis of risk for infection.

Which of the following recommendations would a nurse advocate during infancy and childhood to help reduce potential adult complications such as orchitis? Urge the limited intake of foods and fluids containing caffeine. Ensure immunizations against infectious diseases such as mumps. Encourage the consumption of foods that are rich in fat and starch. Engage in activities and exercises that minimize heavy lifting.

Ensure immunizations against infectious diseases such as mumps Nurses should advocate for infant and childhood immunizations against infectious diseases such as mumps to reduce potential adult complications such as orchitis. Minimizing activities involving heavy lifting or urging limited intake of caffeine have no effect on the potential for adult complications such as orchitis. The nurse should encourage foods that are low in fat and starch; however, this also would have no effect on the potential for orchitis.

Which of the following is the role of the nurse toward a patient who is to undergo eye examinations and tests?

Ensuring that the patient receives eye care to preserve his or her eye function and prevent further visual loss

Skin is largest organ system of the body and has 3 layers called?

Epidermis: outermost layer of stratified epithelial cells, composed predominantly of keratinocytes. Thickest is on palms of hands and soles of feet. Dermis: largest portion of the skin; providing strength and structure. There are 2 layers. The papillary dermis is composed primarily of fibroblast cells capable of producing collagen, a connective tissue. The reticular dermis lies beneath the papillary dermis and produces collagen and elastic bundles. Dermis contains blood, lymph vessels, nerves, sweat and sebaceous glands, and hair roots. The "true skin". Subcutaneous Tissue (Hypodermis): inner layer of skin. Fat (adipose) tissue. Provides a cushion between skin layers, muscles, and bones. Promotes skin mobility, molds body contours, and insulates the body.

This condition is due to a mutation in keratin 5 and 14 and has different variants.

Epidermolysis bullosa simplex

A client is ordered continuous bladder irrigation at a rate of 60 gtt/minute. The nurse hangs a 2 L bag of sterile solution with tubing on a three-legged I.V. pole. She then attaches the tubing to the client's three-way urinary catheter, adjusts the flow rate, and leaves the room. Which important procedural step did the nurse fail to follow? Counter-balancing the I.V. pole Collecting a urine specimen before beginning irrigation Attaching the infusion set to an infusion pump Evaluating patency of the drainage lumen

Evaluating patency of the drainage lumen The nurse should evaluate patency of the drainage tubing before leaving the client's room. If the lumen is obstructed, the solution infuses into the bladder but isn't eliminated through the drainage tubing, a situation that may cause client injury. Balancing the pole is important; however, the nurse would have had to address this issue immediately after hanging the 2 L bag. Using an I.V. pump isn't necessary for continuous bladder irrigation. Unless specifically ordered, obtaining a urine specimen before beginning continuous bladder irrigation isn't necessary.

A client has been prescribed eye drops for the treatment of glaucoma. At the yearly follow-up appointment, the client tells the nurse that she has stopped using the medication because her vision did not improve. Which action by the nurse is appropriate?

The nurse is caring for a patient suspected of having renal dysfunction. When reviewing laboratory results for this patient the nurse recalls that several substances are filtered from the blood by the glomerulus and these substances are then excreted in the urine. The nurse identifies the presence of which substances in the urine as abnormal findings? a) Glucose and protein b) Creatinine and chloride c) Potassium and sodium d) Bicarbonate and urea

Glucose and protein The various substances normally filtered by the glomerulus, reabsorbed by the tubules, and excreted in the urine include sodium, chloride, bicarbonate, potassium, glucose, urea, creatinine, and uric acid. Within the tubule, some of these substances are selectively reabsorbed into the blood. Glucose is completely reabsorbed in the tubule and normally does not appear in the urine. However, glucose is found in the urine if the amount of glucose in the blood and glomerular filtrate exceeds the amount that the tubules are able to reabsorb. Protein molecules are also generally not found in the urine because amino acids are also filtered at the level of the glomerulus and reabsorbed so that it is not excreted in the urine.

Hair:

Hair is present everywhere except the palms and soles. Hair grows in a cavity called a hair follicle. Hair undergoes cycles of growth and rest. The growth phase (anagen) may last up to 6 years for scalp hair, resting phase (telogen) last 4 months. Hair sheds during telogen. Growth of hair on the face, chest and back, is controlled by the male hormones known as androgens. Women with higher levels of testosterone have hair in areas generally considered masculine. May indicate hormonal imbalance. Eyebrows and lashes filter out dust, bugs, and airborne debris. Loss of melanin in hair shaft results in gray or white hair. Hair quantity and distribution can be affected by endocrine conditions. Cushing syndrome causes hirsutism (excessive hair growth). Hypothyroidism causes changes in hair texture. Chemotherapy and radiation therapy cause hair thinning or weakening of the hair shaft. Several autoimmune disease (lupus and alopecia areata) cause hair loss in smaller defined areas. Folliculitis of the scalp will cause inflammation of the hair roots and scarring alopecia.

The nurse is caring for a client ordered for multiple eye screening. Following which procedure will the nurse instruct the client on a yellow coloring to the skin and urine as being normal?

Retinal Angiography

Glands of Skin (2 types):

Sebaceous glands are associated with hair follicles. They secrete sebum onto the space between the hair follicles and the hair shaft, lubricating the hair and making skin soft and pliable. Sweat glands are all over the body but are most concentrated in the palms and soles. Only the glans penis, the margins of the lips, the external ear, and the nail bed are devoid of sweat glands. There are 2 types of sweat glands: eccrine and apocrine. Eccrine glands are found everywhere on skin. They secrete sweat, which is predominately composed of water. Sweat is released in response to elevated ambient temperature and body temperature. Rate of sweat is controlled by the sympathetic nervous system. Apocrine sweat glands are larger than eccrine glands. Located in axillae, anal region, scrotum, and labia majora. They become active at puberty. They produce a milky sweat that is sometimes broken down by bacteria causing body odor. Ceruminous glands, apocrine glands of the ear, produce cerumen (ear wax).

A nurse is explaining the importance of sunlight on the skin to a woman with decreased mobility who rarely leaves her house. The nurse would emphasize that ultraviolet light helps to synthesize what vitamin? D

Specific gravity 1.035 Specific gravity is reflective of hydration status. A concentrated specific gravity, such as 1.035, is suggestive of dehydration. Bright yellow urine suggests ingestion of mulitiple vitamins. Proteinuria can be benign or be caused by conditions which alter kidney function. Creatinine measures the ability of the kidney to filter the blood. A level of 0.7 is within normal limits.

The nurse is reviewing the client's urinalysis results. The finding that is most suggestive of dehydration of the client is: a) Specific gravity 1.035 b) Creatinine 0.7 mg/dL c) Bright yellow urine d) Protein 15 mg/dL

Specific gravity 1.035 Specific gravity is reflective of hydration status. A concentrated specific gravity, such as 1.035, is suggestive of dehydration. Bright yellow urine suggests ingestion of mulitiple vitamins. Proteinuria can be benign or be caused by conditions which alter kidney function.

Spend time outdoors at least twice per week

Gerontologic Considerations

Sun exposure, systemic diseases, and poor nutrition increases the range of skin conditions. Medications (antihistamines, antibiotics, and diuretic agents) increase photosensitivity. The major changes in the skin of older people include dryness, wrinkling, uneven pigmentation, and various proliferative lesions. There is thinning at the junction of the dermis and epidermis. The result of this thinning is fewer anchoring sites between the two skin layers, meaning minor injury can cause it to shear away from the dermis. The epidermis and dermis become thin and flat with age causing wrinkles, sags, and overlapping skin folds. Loss of subcutaneous tissue substances of elastin, collagen, and fat. This decreases muscle tone and the insulating properties of fat (warmth). Cellular replacement slows as a result of aging. The skin becomes fragile and transparent. Blood supply to the skin decreases with age and capillary loops decrease with number and age. This means increased wound healing time. Sweat and sebaceous glands decrease in number leading to dry skin. Hair growth diminishes over lower legs and feet, pubic areas, scalp, and axilla. Loss of sensory perception. Aging of skin from the sun causing lesions and wrinkling.

Which of the following should be included as part of the home care instructions for a patient with epididymitis and orchitis? -Resume sexual intercourse -Apply ice to the area after scrotal swelling subsides -Take prescribed antibiotics -Undertake lifting exercises

Functions of the Skin Protection, Sensation, Fluid Balance, Temperature Regulation, Vitamin Production, Immune Response Function

The skin is no more than 1 mm thick but protects us from bacteria, trauma, water loss, environmental factors (chemicals, microbes, insect bites). The receptor endings of nerves in the skin allow the body to constantly monitor the conditions of the immediate environment. The main functions are temperature, pain, light touch, and pressure (heavy touch). The stratum corneum, the outermost layer of the epidermis, has capacity to absorb water. This prevents loss of water and electrolytes. Insensible evaporation, amount of water continuously evaporating from skin, is about 600 mL daily. The body continuously produces heat as a result of metabolism of food, which produces energy. Heat loss is from 3 major physical processes: radiation, evaporation, conduction. Radiation is the transfer of heat to another object of lower temperature situated at a distance. Evaporation from the skin aids heat loss by conduction. Heat is conducted through the skin into water molecules onto water molecules on its surface, causing water to evaporate (perspiration). The rate of heat loss depends on the surface temperature of the skin. On cold days, the blood vessels constrict to reduce heat loss. And on hot days the body sweats in order to regulate heat loss. Vitamin D is essential for preventing osteoporosis and rickets. People need 5-30 minutes of sun exposure twice a week in order for this synthesis to occur. Langerhans cells facilitate the uptake of immunoglobulin E (IgE)-associated allergens. This action plays a pivotal role in the pathogenesis of atopic dermatitis and other allergic diseases such as asthma and allergic rhinitis.

The nurse is caring for a client who is brought to the emergency department after being found unconscious outside in hot weather. Dehydration is suspected. Baseline lab work including a urine specific gravity is ordered. Which relation between the client's symptoms and urine specific gravity is anticipated? a) The specific gravity will be high. b) The specific gravity will be inversely proportional c) The specific gravity will be low d) The specific gravity will equal to one

The specific gravity will be high. The nurse assesses all of the data to make an informed decision on client status. On a hot day, the client found outside will be perspiring. When dehydration occurs, a client will have low urine output and increased specific gravity of urine. Normal specific gravity is inversely proportional. The density of distilled water is one. A low specific gravity is noted in a client with high fluid intake and who is not losing systemic fluid.

The nurse is reviewing the client's lab results. Which lab result requires follow up by the nurse? Select all that apply.

Urine: RBC 20 BUN 28 mg/dL Hematuria (> 3RBCs) and an elevated BUN are both suggestive of a problem within the genitourinary tract. A serum creatinine of 0.8 mg/dL and a urine specific gravity of 1.020 are within normal limits. A rare white blood cell is not clinically significant.

Which of the following instructions regarding future sexual activity should a nurse give a patient with a vasectomy?

Use a reliable method of contraception until the physician ensures that sperm are no longer present.

Which assessment finding would create the greatest risk to a client ordered a phosphodiesterase inhibitor such as sildenafil? Use of nitrates Type 2 diabetes History of hypertension Use of diuretics

Use of nitrates PDE5 inhibitors facilitate penile erection by producing smooth muscle relaxation in the corpora cavernosa via vasodilation of the blood vessels. If a client is using nitrates (which also exhibit vasodilation) hypotension is likely to occur. History of hypertension and diabetes does not interfere with the administration of PDE5 inhibitors. Use of diuretics is not significant.

A client diagnosed with prostate cancer is to receive brachytherapy. Which of the following would the nurse include when discussing this therapy with the client? Need for daily treatments over a 7- to 8-week period Surgical castration to decrease the level of circulating testosterone Use of probes inserted using ultrasound to freeze the tissue Use of radioactive seeds implanted into the prostate

Use of radioactive seeds implanted into the prostate Brachytherapy involves the implantation of interstitial radioactive seeds under anesthesia. External beam radiation therapy (teletherapy) involves the use of radiation treatments, usually 5 days/week over 7 to 8 weeks. Surgical castration is a type of androgen-deprivation therapy. Cryosurgery invovles the insertion of transperineal probes into the prostate to freeze the tissue directly.

A client in a short-procedure unit is recovering from renal angiography in which a femoral puncture site was used. When providing postprocedure care, the nurse should: a) check the client's pedal pulses frequently. b) remove the dressing on the puncture site after vital signs stabilize. c) keep the client's knee on the affected side bent for 6 hours. d) apply pressure to the puncture site for 30 minutes.

check the client's pedal pulses frequently. After renal angiography involving a femoral puncture site, the nurse should check the client's pedal pulses frequently to detect reduced circulation to the feet caused by vascular injury. The nurse also should monitor vital signs for evidence of internal hemorrhage and should observe the puncture site frequently for fresh bleeding. The client should be kept on bed rest for several hours so the puncture site can seal completely. Keeping the client's knee bent is unnecessary. By the time the client returns to the short-procedure unit, manual pressure over the puncture site is no longer needed because a pressure dressing is in place. The nurse should leave this dressing in place for several hours — and only remove it if instructed to do so.

Stages of Glaucoma: Structural alterations in the aqueous outflow system

not draining properly or no drainage causes pressure to build up o Tissue and cellular changes caused by factors that affect aqueous humor dynamics lead to structural alterations and may lead to the third stage

Medical management: Ocular Burns or Chemical Burns cont.

o A brief history and examination are performed • Critical information includes the name of the substance that went into the eye • Material safety data sheets (MSDS) should be accessed for reference as to how to treat that certain chemical o Prognosis depends on the type of injury and adequacy of the irrigation immediately after exposure

Nursing Management for retinal detachment: Education post surgery

o Activity restriction, no straining to reduce pressure o Wear an eye shield to protect the eye o Importance of seeking treatment for changes in vision or any complication such as drainage or pain/pressure that may occur

Pre-operative care for cataract surgery: Cont.

o Alpha-antagonist, particularly tamsulosin (Flomax), are known to cause a condition called intraoperative floppy iris syndrome • Can interfere w/ pupil dilation during surgery, resulting in miosis and iris prolapse and leading to complications • Can still occur even if the patient has stopped taking the medication • Nurse needs to ask pts about history of taking alpha-antagonists so surgical team can be alerted

Stages of glaucoma: Optical nerve damage

o Atrophy of the optic nerve is characterized by loss of nerve fibers and blood supply o This fourth stage inevitably progresses to the fifth stage

Glaucoma medications:

o Comfort, affordability, convenience, lifestyles, and personality are factors to consider in the patient's adherence to the medical regimen

Anti-allergy Medications

o Common for a pt with allergies o Not going to get into specific names or brands - just know there are allergy meds for the eye

Pre-operative care for cataract surgery: Cont.

o Common practice to withhold any anticoagulant therapy to reduce the risk of retrobulbar hemorrhage for 5 to 7 days before surgery • A recent study showed that the risk of adverse events for patients who continued anticoagulant therapy before cataract surgery was very low - up to the physician but MUST notify them about this • Researchers speculated that regular users of aspirin or warfarin are already at higher risk for transient ischemic attacks or angina and suggest that patients may not need to discontinue these medications prior to surgery

Pre-operative care for cataract surgery: Cont.

o Dilating drops are administered prior to surgery • Every 10 minutes for four doses at least 1 hour before surgery - Additional drops may be administered in the operating room o Nurses begin pt education about eye medications - Antibiotic, corticosteroid, and anti-inflammatory drops - that will need to be self-administered to prevent postop infection and inflammation

Nursing Management for Pts with Glaucoma: Glaucoma

o Disturbed Sensory Perception: Visual o Risk for Injury o Anxiety

Potential Early Postop Complication (not on chart) of cataract surgery: Cont.

o Effects - Corneal edema less than 24 hours postop o Symptoms - reduced visual acuity and pain o Management and Outcome - If there is no growth of microorganism, the treatment is topical steroids alone

Exudative/Wet/Neovascular macular degeneration (Abrupt onset)

o Formation of new, weak blood vessels between vessel layers and retina o New blood vessels are weak and prone to leaking, which interferes with vision o Repeated bleeding will cause scarring o Straight lines appear crooked and distorted or that letters in words appear broken o Blurred vision centrally - peripheral vision usually stays intact

Continuing Care for cataracts:

o If an eye patch is worn, it is removed after the first follow up appointment, usually within 48 hours after surgery o Educate patients on the importance of keeping their follow up appointments • Monitoring of visual status and prompt intervention of post op complications enhance good visual outcome

Ocular trauma: Chemical burns

o Immediately irrigate the eye with tap water or normal saline o pH of the eye should be assessed

Nursing Management for retinal detachment: complications

o Increase in IOP o Endophthalmitis o Other retinal detachments o Development of cataracts • Must be taught the signs and symptoms of complications, particularly of increasing IOP and postoperative infection • Given telephone numbers and instructed to call immediately if discomfort escalates • Diagnoses - Ineffective Tissue Perfusion: Retinal and Anxiety

Medical Management: Splash Injuries

o Irrigate with normal saline before further evaluation occurs o Further manipulation should be avoided until the patient is under general anesthesia o Parental broad spectrum antibiotics o Tetanus antitoxin is administered, if indicated, as well as analgesic agents o Any topical ophthalmic medication must be sterile

Natural barriers of absorption that diminished the efficacy of ocular medications include:

o Limited size of the conjunctival sac o Corneal membrane barriers o Blood-ocular barriers o Tearing, blinking, and drainage • Increased tear production, excessive drainage, or excessive blinking may dilute or wash out an instilled eye drop

Non-exudative/Dry/Non-neovascular macular degeneration (usually occurs slowly)

o Most common type - between 85%-90% of people have dry type o Outer layer of the retina slowly break down - appearance of drusen occurs o Drusen outside of the macular area - no symptoms o Drusen within the macula - gradual blurring of vision that patients may notice when they try to read o Usually occurs slowly

Medical management: Penetrating Injuries and Contusions of the Eyeball

o Most penetrating injuries result in marked vision loss and usually have the following manifestations: • Edema of the conjunctiva (hemorrhagic chemosis) • Conjunctival laceration • Shallow anterior chamber with or without an eccentrically placed pupil

Glaucoma medications: Main treatment

o Must control increased IOP and prevent optic nerve damage o Cannot be cured or reversed o Relies on systemic and topical ocular medications that lower IOP o Takes into account the patients' health and stage of glaucoma

Medical management: Ocular Burns or Chemical Burns

o Must test the pH of the solution o Alkali burns (lye or ammonia) result in the most severe injury because they penetrate the ocular tissues rapidly and continue to cause long-term damage - can also cause increased IOP o Acids (bleach, car batteries, refrigerant) generally cause less damage because the precipitated necrotic tissue proteins form a barrier to further penetration and damage o In treating chemical burns - urgency is of importance

Ocular trauma: Foreign bodies

o No attempt should be made to remove it o The object should be protected from jarring or movement to prevent further ocular damage o Wouldn't want to put any type of pressure or patch on the affected eye

Medical management: Foreign bodies and corneal abrasions

o Removed by the physician o Antibiotic ointments are applied and the eye may be patched if it's a corneal abrasion o Contact lens wear is a common cause of corneal abrasion o Topical anesthetic eye drops must not be given to the patient to take home for repeated use after corneal injury because their effects mask further damage, delay healing, and can lead to corneal scarring

Promoting home and community based care for cataract surgery:

o Slight morning discharge, some redness, and a scratchy feeling may be expected for a few days o A clean, damp washcloth may be used to remove slight morning eye discharge o Because cataract surgery increases the risk of retinal detachment, the patient must know to notify the surgeon if new floaters (dots) in vision, flashing lights, decrease in vision, pain, or increase in redness occurs

Promoting home and community based care for cataract surgery:

o To prevent accidental rubbing or poking of the eye, the patient wears a protective eye patch for the first 24 hours after surgery, followed by eyeglasses worn during the day and an eye shield at night for 1 to 4 weeks o Educate the patient and family about applying and caring for the eye shield o Sunglasses should be worn while outdoors during the day because the eye is sensitive to light

Aqueous solutions are most commonly used for the eye:

o Topical routes (instilled eye drops and applied ointments) are the most commonly used for ocular disorders o Least expensive and interfere w/ vision the least o However, corneal contact time is brief o Ointments have extended retention time in the conjunctival sac and provide a higher concentrate than eye drops

Treatments for Non-exudative/Dry Type - No known cure

o Use of antioxidants (vitamin C, vitamin E and beta carotene) and minerals (zinc oxide) in megadoses can slow the progression of AMD and vision loss for people at high risk for developing advanced AMD

Topical Anesthetic Agents:

o Used before diagnostic procedures or for pts having severe eye pain o Anesthesia occurs between 20 seconds - 1 minute and can last from 10 - 20 minutes o Nurses must educate pts to not rub eyes - this can cause corneal damage o Pts are not usually allowed to take meds home due to risk of overuse - can cause softening of the cornea o Prolonged use can result in delayed healing & can lead to permanent corneal opacification and scarring, resulting in visual loss

Corticosteroids and NSAIDS

o Used for inflame conditions of eye o When a suspension is prescribed, instruct pt to shake the bottle prior to use

Orbital Fractures

o Usually non emergent and require surgical repair o Detected by facial x-rays

Mydriatic and Cycloplegic Agents

o Usually used in combo for max. pupil dilation o Educate on the temporary effects: glare, inability to focus properly, difficulty reading o Effects can last from 3 hours to several days o Advise to wear sunglasses o Ability to drive depends on the individual's age, vision, and comfort level o These agents affect the CNS and are most prominent in younger and older adults - these pts must be assessed closely for symptoms

Continuing Care for cataracts: cont.

o Vision is stabilized when the eye is completely healed, usually within 6 to 12 weeks, when final corrective prescription is complete o Visual correctives may still be needed for any remaining refractive errors o Patients who choose multifocal IOLs should be aware that there may be increased night glare and contrast sensitivity

Foreign bodies

o Would do an xray or CT to detect o Surgical intervention is directed at preventing further ocular injury and maintain the integrity of the affected areas o Cultures are usually obtained, and the pt is placed on prophylactic IV antibiotics that are later changed to ones in a n oral form
