Q

Hypernatremia

A

Na+ > 145 mEq/L
Sodium maintains blood pressure and blood volume
Caused by:
Loss of fluid (infection, diarrhea, persistent sweating)
Diabetes –> dehydrates because it causes ADH insufficiency
Sodium Excretion Impaired –> Renal problems (caused by corticosteroids sometimes)
Too much processed foods
Deprivation of fluids (hemoconcentration)
IV Hypertonic sol’n excess (too much 3-5% saline)
Vitamins / sodium supplements like alka seltzer, aspirin, cough syrups
Aldosterone excess –>
(hypercortisolism) holds Na+ in the body, resulting in weight gain and moon face (Cushings’ disease)

Q

Hypokalemia S&S

A

Everything is slow & low
K+ plays an important role in muscle and nerve conduction. So, low K+ becomes slow and low (exhausted body):
weak, thready pulse
orthostatic HTN
Decreased bowl sounds
decreased deep tendon reflexes
flaccid paralysis (late with very low paralysis)
confusion
Shallow respirations/ diminished breath sounds (no K+ means low ability of accessory muscles)
7Ls:
Lethargic
Low/shallow breathing
Lethal cardiac changes
Loss of urine (diuretics)
Leg cramps
limp muscles
low BP & HR

EKG –> depressed ST segment, flat or inverted T wave, prominent U wave

Q

Hypokalemia RN Interventions

A

Monitor:
> Heart rhythms
> respiratory status
> GI & Renal status
> I/O
> Magnesium (Mg+ and K+ are linked)
> Glucose, Ca2+, Na+ because of the roles in cell transport
> K+ supplement for 2.5 - 3.5; give with food to avoid GI upset
> K+ infusion for <2.5; this is NEVER given as an IV Push, or IM or SubQ. Give slowly via IV. no more than 20 mEq/L per hour. Watch for phlebitis and infiltration
> Hold diuretics that waste K+ and cause urination. Notify the MD. May switch to K+ sparing such as spironolactone/aldactone, dyazide, maxide, triamterene.
> Check apical pulse and AM labs before giving digoxin.

Q

Hypophosphatemia Causes

A

<2.7 mg/dL
low “PHOSPHATE”
P = Pharmacy: aluminum hydroxide and aluminum based antacids cause malabsorption which reduces phosphate absorption. Also, lack of Vit D.

H = Hyperparathyroidism: PTH is too high in the serum, which inhibits the reabsorption of phosphate in the kidneys and it is excreted.

O = oncogenic osteomalacia –> kidneys waste phosphate due to bones softening.

S = syndrome of refeeding. Watch for this on patients TPN; occurs in malnutrition or starvation pathologies. The body was in starvation mode and when it gets nutrients, it releases way too much insulin. It then releases phosphate and magnesium to help digest (but they were already too low to begin with)

P: pulmonary issues due to respiratory alkalosis b/c phosphate moves out of the blood and into the cell.

H: Hyperglycemia leads to glycosuria, polyuria, and ketoacidosis. Causes the kidney to waste phosphate.

A: Alcoholism impacts the body’s ability to absorb phosphate. plus, alcoholism is associated with malnutrition.

T: thermal burns – extreme burns causes a shift of phosphate out of the blood and into the cells.

E: electrolyte imbalances cause low phosphate levels like hypERcalcemia, hypOmagnasemia, and hypOkalemia.

Q

Hypophosphatemia S&S

A

“BROKEN” (the patient is at risk for bone fractures and every system of the body is breaking down!)

B = breathing problems due to muscle weakness

R = Rhabdomyolysis, an electrolyte disturbance due to low levels of Phosphate, K+. Affects the muscles and causes rapid necrosis of the muscles. This releases myoglobulin into the blood, which is toxic to the kidneys causing tea-colored urine, muscle-weakness, and pain.

also deep tendon reflexes will decrease

O = osteomalacia: bone fractures, deformities

Also, Cardiac outpute is decreased

K= kills immune system through decreased platelet aggregation (increased bleeding)

E = extreme weakness and ecchymoses ( due to decreased platelets)

N = neuro changes such as irritability, confusion, seizures

Q

Hypophosphatemia RN Interventions

A

MD orders oral phosphorous w/ vit D to help with absorbption

Monitor patients on TPN for muscle pain and weakness (rhabdomyolosis), also re-feeding syndrome

Ensure patient safety (bed down, call light in reach) due to risk for fractures and confusion

Encourage foods rich in phosphate

If <1.7 the MD may order IV phosphate. Be careful with patients who are in renal failure, because they can’t clear the phosphate.

Monitor Ca2+ level, as this can decrease if the phosphate gets higher.

Monitor phosphate levels to avoid hyperphosphatemia

Monitor EKG changes

Q

Hyperphosphatemia Causes

A

> 4.5 mg/dL
“PHOSHI” –> note that Phoslo is a phosphate binding drug that patients in renal failure take to keep phosphate low (because the kidneys can’t get rid of phosphate anymore)

P: Phospho-soda overuse. Laxatives and enema overuse

H: HypOparathyroidism causes high phos levels due to PTH being too low. PTH causes the kidneys to keep too much phosphate.

O: overuse of Vit D, which supports absorption of phosphate

S: syndrome of tumor lysis, which occurs with chemo. Chemo kills off good and bad cells. This lets out the phosphate which is normally inside the cell into the ECF.

H: rHabdomyolysis –> rapid necrosis of muscles. Dead muscles release myoglobulin into the blood, which is toxic to the kidneys, which sends the patient into renal failure and phosphate excretion is decreased.

I: insuffiency of the kidneys (ESRF) which means phosphate won’t be excreted.

Respiratory center compensates by becoming depressed, decreasing the rate and depth to retain CO2

89
Q

Respiratory Alkalosis Clinical Manifestations

A

HyPERventilation causes a CO2 deficit, which leads to respiratory alkalosis due to a decreased concentration of carbonic acid (H2CO3) in the blood.

HypOkalemia, HypOcalcemia - tetany
Cardiac arrythmias
Blurred vision
Headache
Warm/flushed skin
high pulse rate
muscle weakness
Dyspnea, chest tightness, dizziness, anxiety, panic, blurred vision

Hyperthermia can cause the hyperventilation

Hypokalemia –> K+ moves out from the cells in exchange for H+ ions

HypOcalcemia –> alkalosis causes binding of Ca2+ to albumin, causing symptoms of hypocalcemia: numbness and tingling of the mouth and fingers.

Pressure is usually between 5-20 cm of water.

144
Q

BiPAP (Bilevel Positive Airway Pressure)

A

Provides assistance during inspiration and keeps the airway open during exhalation.

It increases the amount of air in the lungs at the end of expiration, reduces airway closure, and improves O2.

145
Q

Asthma Etiology

A

In Asthma, the airway becomes constricted and histamine is released. Most common in kids.

Usually caused by exposure to an allergy or trigger, such as dander, foods, nuts, drugs, exercise induced, weather induced (usually cold), irritants, genetics, exposure to smoke, allergies, or a respiratory infection.

The loss of heat or moisture from the bronchial surface is a characteristic of exercise-induced asthma, which is triggered by exercising in cold, dry air.

146
Q

Asthma Clinical Manifestations

A

150
Q

Asthma Nursing Interventions

A

Acute episodes are managed by ‘rescue medications’ such as bronchodilators (Albuterol), Anticholinergics (Atrovent) - to prevent further bronchoconstriction, and steroids such as methylprednisone to reduce inflammation.

LT mgmt use of Long-Acting Beta Agonists

Assess respiratory and O2 status

Identify triggers/precipitating factors

Create an Asthma Action Plan

151
Q

Asthma Patient Education

A

Rescue vs. maintenance

Proper use of meds

152
Q

Anticholinergics (tiotropium / Spiriva) Mechanism of Action in Asthma

A

Blocks the cholinergic receptors of the Parasympathetic Nervous System, which allows the Sympathetic Nervous System to dominate.

Releases Epinephrine, relaxes smooth muscles around the airways, and promotes bronchodilation.

Tiotropium is administered through inhalation.

153
Q

Anticholinergics (tiotropium / Spiriva)
Nursing Considerations

A

Assess for allergies to soybean/peanuts
Use cautiously during lactation, pts with glaucoma, prostatic hypertrophy

Assess for improved gas exchanged, decreased chest tightness, and decreased dyspnea

After use, offer mouth rinses to relieve dry mouth and bitter taste.

154
Q

SABA - Short Acting Beta-2 Adrenergics
(Albuterol and Levalbuterol)

Mechanism of Action

A

Activates the Sympathetic Nervous System beta-2 receptors to relax bronchial smooth muscles causing bronchodilation.

Relieves bronchospasms for improved gas exchange in patients experiencing an acute asthma attack.
“Rescue inhaler” – works within minutes

155
Q

SABA & LABA

Nursing Considerations

A

Use cautiously in pts with high BP, CAD, cardiac arrhythmias, and diabetes.

Inhalation is the desired route to minimize adverse systemic effects.

Should be administered with a MDI, DPI, or nebulizer.

Desired effects are a reduction in tachypnea, work of breathing, wheezing, and anxiety

Observe for signs of tremors, as beta2 agonists may activate the beta2 receptors in skeletal muscles.

156
Q

SABA & LABA
Delivery Education

A

MDI is the most common method of delivery

Instruct the patient to depress the canister while taking slow, deep breaths for the most precise dose.

When 2 puffs are needed, wait for 1 minute between puffs.

Take Rescue inhaler 5 minutes before any other inhaled drugs, since the bronchodilator effects will impact those.

Monitor HR for tachycardia (SABAs have systemic effects)

157
Q

Long Acting Beta Agonist
(arformeterol/Brovana; Formoterol / Perforomist; indacaterol / Arcapta)

Mechanism of Action

A

Not recommended for acute attacks due to a 30 minute onset.

Some LABAs (salmeterol) have an increased risk of asthma-related deaths b/c patients try to use them as a Rescue Inhaler.

Combination products include a LABA with a corticosteroid.

158
Q

Corticosteroids for Asthma
(beclomethasone/Qvar; fluticasone/Flovent; prednisolone/Orapred)

Mechanism of Action

A

Not beneficial for acute attack!

Suppress inflammation in the airways and decrease mucus production.

Reduces the impact of exacerbations, improves speed of recovery, and decreases rate of relapse.

Combination salmeterol/fluticasone lasts as long as 12 hours, but takes 30 minutes to work so can’t be used for acute attacks.

159
Q

Corticosteroid Nursing Considerations

A

Administer each dose of the corticosteroid about 5-10 minutes after the inhaled dose of bronchodilators to enhance the distribution of medication into the lungs.

Assess for throat irritation, nasal dryness, and oral/laryngeal candidias.

Administer antifungals or gargles as directed by HCP.

160
Q

Corticosteroid Patient Education

A

Rinse mouth after each use to decrease throat irritation and reduce the risk of fungal infections.

NOT for acute attacks!

Could take a couple of weeks to experience the beneficial effects.

Take the medication continuously and refrain from stopping during symptom-free periods to ensure that therapeutic levels are maintained.

161
Q

Leukotriene Modifiers
(Monelukat/singulair; zafirlukast/accolate; zileuton/Zyflo)

Mechanism of Action

A

NOT FOR ACUTE ATTACKS. These are a 2nd line therapy if an ICS cannot be used or adjunctive if ICS is insufficient.

Suppress inflammation and the release of leukotrienes/other inflammatory mediators. This results in less edema, mucus production, and airway obstruction.

May have adverse effects of depression and suicidal thinking.

162
Q

Leukotriene Modifiers
Nursing Considerations

A

With Exercise-Induced Bronchoconstriction (EIB), take meds at least 2hours before exercising.

NOT for an acute attack!

Monitor liver function tests

May increase levels of warfarin, resulting in bleeding.

163
Q

Mast Cell Stabilizers
(cromolyn)

A

Stabilize mast cell membranes and prevent the release of inflammatory mediators, such as leukotrienes, histamines.

This reduces edema, mucus production, and airway obstruction.

Also used to prevent asthma attacks triggered by inflammation/allergens.

Administered by MDI or nebulizer and are relatively safe with few side effects.

164
Q

Mast Cell Stabilizers (Cromolyn)
Nursing Considerations & Education

A

Assess for decreased frequency of asthma attacks, wheezing, and bronchoconstriction.

Use daily, even when asymptomatic.

Use the MDI correctly!! (use teach-back when training)

NOT FOR ACUTE ATTACKS.

165
Q

Methylxanthines
(aminophylline and theophylline)

Mechanism of action

A

Dual actions: CNS stimulant and bronchodilator.
As a CNS stimulant, methylxanthines decrease drowsiness and fatigue, but higherdoses may produce nervousness, insomnia, and tremors.

As a bronchodilator, they relax the bronchial smooth muscles.

Methylxanthines are infrequently used, as there is a narrow margin of safety and many side effects.

166
Q

Methylxanthine Nursing Considerations

A

Avoid caffeine, as this increases the level of toxicity.

Adverse effects include insomnia, gastric distress, nausea, vomiting, and CNS stimulation. Cardiac dysrhythmias may be observed at higher dosages.

Monitor serum levels of the drugs to assure they’re at a therapeutic level.

167
Q

Methylxanthine Patient Education

A

NOT a rescue inhaler

Contact HCP about OTC drugs due to possible interactions.

Monitor serum theophylline levels to avoid toxicity.

Educate on adverse effects and tell patient to report adverse effects.

168
Q

Monoclonal Antibodies
(benralizumab/Fasenra; dupilumab/Dupixent; Mepolizumab/nucala)

A

Inhibits several types of interleukins to decrease an inflammatory response.

Administer by subcutaneous injection, except for reslizumab - which is given IV.

Instruct the patient or family member how to do a subQ injection.

Q

COPD def’n

A

Incurable, irreversible chronic lung disorder with two main components:
1. chronic bronchitis – inflammation and excessive mucus. productive cough that has lasted 3+ months in 2 consecutive years.
2. Emphysema– alveolar membranes break down (usually due to a long history of cigarette smoking)

Low pO2 becomes the stimulus for breathing, so it’s important to only give the lowest amount of O2 possible to remain stable.

170
Q

COPD Etiology

A

Age related - 50+
Current/past smoker
Respiratory infection - frequent trigger for exacerbation of symptoms
Occupation - chemicals, dust, air pollution, infections
Antitrypsin deficiency - “AAT” inherited, it normally protects the lungs from injury.

171
Q

COPD Clinical Manifestations

A

Easily fatigued
Frequent URIs
Use of accessory muscles to breathe
Orthopneic
Wheezing
pursed lip breathing
Chronic cough
Barrel chest
Dyspnea
Prolonged expiratory time
Bronchitis - increased sputum
Digital clubbing
Worsening ABGs

172
Q

COPD Collaborative Treatments

A

Stop smoking!!
low flow O2 (goal is 88-92%)
CPAP or BiPAP
breathing treatments
sitting position or tripod position
Breathing techniques:
> abdominal breathing relieves the work of the accessory muscles
> pursed lip breathing slows the respiratory rate and helps maintain open airways.
Huff Coughing: inhale deeply while leaning forward, exhale sharply with a ‘huff’ sound
Controlled Coughing: inhale deeply, hold breath briefly, cough twice; inhale by sniffing
Small meals that are high in protein; hydration
Chest physiotherapy

173
Q

What is Pneumonia

A

Pneumonia is acute inflammation of the lung.
The inflammatory response causes fluid to accumulate in the alveoli and edema to form as alveolar capillaries dilate and allow fluid to leak into interstitial tissues. This results in impaired gas exchange, causing the patient to become dyspneic.

174
Q

Bacterial Pneumonia

A

70% of cases
Upper respiratory tract infection
Risk factors: air pollution, cigarette smoking, medication, alcohol, COPD, heart failure, kidney failure

175
Q

Aspiration pneumonia

A

patient aspirates gastric contents into the lungs, and this causes pneumonia.
Risk is highest during emergency surgery, because the patient hasn’t stopped eating.
other risks include decreased LOC, dysphagia, nasogastric intubation, 65+ yo, abdominal/chest surgery, tube feeding, vomiting

176
Q

Viral pneumonia

A

10% of the adult population.
Flu and adenovirus are most common causes, but herpes and measles can also lead to pneumonia.
Mostly found in immunosuppressed patients.

177
Q

Pneumonia Clinical Manifestations

A

Cough
Chills
Fever
Tachypnea
Dyspnea
Chest pain
Sputum
Fatigue
Decreased LOC

178
Q

Diagnostics / Labs for Pneumonia

A

Chest X-Ray
Pulse Ox
Sputum –> the sputum gram stain can rapidly identify the infecting organisms, which allows the provider to select the correct antibiotic.
Blood cultures
ABGs
WBCs

179
Q

Pneumonia Treatment

A

Prevention
incentive Spirometry (prevents alveoli collapse)
Chest PT
Suction
Fowlers position
O2 to prevent hypoxemia
Small meals, high in calorie/protein, los in carbs
Encourage movement!
Fluids

180
Q

Sleep Apnea

A

Sleeping disorder when a person stops breathing. The average adult needs 7-9 hours of sleep.
Considered sleep apnea when there are 5+ apneic periods in an hour.
30+ episodes in an hour is considered severe.

181
Q

Sleep Apnea Risk Factors

A

Women who are 60+
Anyone with a mental disorder
Large neck / abdominal circumference
Smoking
Alcohol
Could be genetically linked

182
Q

Sleep Apnea Clinical Manifestations

A

Snoring
Sleeplessness, excessive sleepiness (always tired/irritable)
Fatigue
Irritability
Distractibility
Hard time focusing
Confusion
Morning headaches

183
Q

Sleep Apnea diagnostics

A

Polysomnography Test (PSG) –> records O2 levels, eye movements.
ECG ==> used to measure brain waves

184
Q

Sleep Apnea Treatment

A

Sleep maintaining behaviors
Stimulants for daytime
CPAP
Weight reduction
Possibly surgery to remove the obstruction
Avoid alcohol

185
Q

Sleep Apnea Nursing Assessment

A

Assess apnea episodes
Assess wakefullness
Assess O2 status, SpO2, PaO2, CO2
Headaches

186
Q

Sleep Apnea Patient Education

A

Deep breathing exercises
Positioning upright
promote secretion clearance
limit liquid at night
encourage smoking & alcohol cessation
avoid naps during the day
improve diet
O2 therapy
Exercise regimen
