1
Q

What is an upper respiratory condition?

What are the 4 general categories of upper respiratory conditions?

A

A condition in which the upper respiratory tract is altered.

  • allergic rhinitis
  • infection (viral rhinitis, sinusitis, peritonsillar abscess, pharyngitis)
  • trauma + other altered states
  • obstruction (foreign body or swelling)

Q

What causes acute viral rhinitis? What spreads it?

What mgmt strategies can be implicated?

A

caused by viruses that invade the upper respiratory tract

spread by airborne droplet sprays emitted while breathing, talking, sneezing or coughing or by direct hand contact

mgmt strategies: rest, fluids, proper diet, antipyretics, analgesics

Q

A client with allergic rhinitis reports severe nasal congestion, sneezing and watery, itchy eyes and nose at various times of the year. What should the nurse advise the client to do?

a. Avoid all intranasal sprays and oral antihistamines
b. Limit the duration of use of nasal decongestant spray to 10 days
c. Use oral decongestants at bedtime to prevent symptoms during the night
d. Keep a diary of when the allergic rxn occurs and what precipitates it.

A

b) should be limited to 3 days, not 10
c) wrong because decongestants wake you up and increase SNS activity

D is correct.

Influenza
Pneumonia
Empyema
Pleural effusion
Pulmonary edema
27
Q

Compare + Contrast Influenza and the Common Cold (Viral Rhinitis) in terms of:

  • onset + duration
  • symptoms
A

Influenza

  • abrupt onset
  • systemic symptoms (fever, myalgia, headache, sore throat, dry cough)
  • risk of pneumonia
  • subsides in 7-10 days
  • treated w influenza vaccine or antivirals in severe cases

COLD (viral rhinitis)

  • gradual onset, mild symptoms
  • tickling, itching, irritation of throat, sneezing + copious nasal secretions, nasal congestion, elevated temperature, malaise, headache
  • subsides in 3-4 days
28
Q

What is pneumonia?

A

Pneumonia is an infection in the alveoli which leads to an inflammatory response.

Alveoli fill with fluid + exudate which affects gas exchange
Consolidation occurs as exudate replaces air in alveoli

29
Q

What are the 3 types of Pneumonia? which is the most common?

A

1) LOBAR pneumonia (most common)
2) Bronchopneumonia
3) Interstitial

30
Q

What is LOBAR pneumonia?

A

Infection of lung lobe or entire lung

31
Q

What is Bronchopneumonia?

A

Scattered patches of infiltrate in both lungs

32
Q

What is Intersitial Pneumonia?

A

Infiltrates in alveolar walls between alveoli

33
Q

Which populations are at a higher risk for pneumonia?

A
  • smokers (4x more likely)
  • alcohol + substance addictions
  • influenza or other viral infection
  • pre-existing lung disease such as COPD
  • neurological disease (ex - paralyzed)
  • renal disease
  • cardiac disease
  • immunocompromised or immunosuppressed patients (such as chemo patients, HIV, organ transplants)
  • v/ young (under 5) or v/ old (over 85 yo)
  • post-op patients (immobile, in pain)
  • ventilated patients
34
Q

What does it mean if a patient’s position of comfort is the tripod position (leaning over, palms of hands on knees)?

A

This position allows lungs to expand more easily, sign of increased WOB

35
Q

What does it mean if we hear coarse crackles on auscultation?

A

Fluid in lungs

36
Q

What does it mean if we hear bronchial breath sounds on auscultation?

A

All sounds heard should be vesicular. This is a sign of decreased air entry.

37
Q

T or F: symptoms of pneumonia are similar to those of a pulmonary embolism?

A

True.

38
Q

What symptoms of pneumonia would we find on inspection?

A
  • dry lips
  • cyanotic oral mucosa
  • accessory muscle use in neck
  • indrawing between intercostal spaces
39
Q

What symptoms of pneumonia would we find on palpation?

A
  • pain over R anterior and lateral chest wall
  • decreased chest expansion of R lung
  • increased fremitus (vibratory tremors) in RML
40
Q

What symptoms of pneumonia would we find on percussion?

A

dullness over RML

41
Q

What symptoms of pneumonia would we find on auscultation?

A

Bronchial breath sounds over RML
Egophony
Whispered petrology
Pleural rub over R lower lung field

42
Q

Which test is used to assess the severity of pneumonia?

How does the test work?

A

CURB65 score (1 point for each feature)

  • confusion
  • urea
  • respiratory rate
  • bp
  • age > 65

a score of 5+ indicated a 57% mortality rate
4 - 42%
3 - 17%
2 - 13%

43
Q

How does pneumonia affect the V/Q ratio?

A

decreases it.

44
Q

how does pneumonia affect the alveoli?

A

alveolar sacs filled w fluid + exudate, alveolar walls thickened therefore increased distance for diffusion required) .

45
Q

How does the body compensate to improve VQ mismatching?

A

hypoxic pulmonary vasoconstriction in areas of low ventilation, redirects blood to areas of better ventilation

46
Q

Can we treat shunt w oxygen?

A

Shunt is difficult to treat with ocygen as the blood will never benefit from increased FiO2

47
Q

What are 3 common intrapulmonary forms of shunt?

A
  • pulm edema
  • pneumnia consolidatino (exudate replaces air in alveoli)
  • atelectasis
48
Q

What occurs as a result of alveolar hypoventilation?

What does alveolar hypoventilation occur in?

A

causes both hypoxemia and hypercapnia

occurs in:

  • opioid use
  • chest wall injury / pain
  • neuromuscular respiratory weakness
  • injury to respiratory center
  • restrictive lung disease
49
Q

What is empyema?

A

pockets of pus that have collected inside the pleural space

forms if a bacterial infection is left untreated or fails to fully respond to treatment.

50
Q

what is pleurisy?

A

inflammation of pleura

51
Q

what are the potential complications of pneumonia in the lung?

A
  • atelectasis
  • pleural effusion
  • empyema
  • pleurisy
  • lung abcess
52
Q

what are 4 other complications of pneumonia?

A

pericarditis
bacteremia –> sepsis
meningitis
endocarditis

53
Q

what is atelectasis?

A

lung collapse or incomplete expansion of the lung or a portion of the lung

54
Q

What are the 3 potential causes of atelectasis?

A

1) airway obstruction (aspiration or mucus plug formation)
2) lung compression (tumot mass, air, fluid)
3) increased alveolar surface tension (ex - decreased surfactant)

55
Q

Question 1:
A client is seen at the clinic with fever, muscle aches, sore throat with yellowish exudate, and headache. Which of the following does the nurse anticipate that the collaborative management will include? (Select all that apply)
a. Antiviral agents to treat influenza
b. Treatment with antibiotics starting ASAP
c. A throat culture or rapid strep antigen test
d. Supportive care, including cool, bland liquids
e. Comprehensive history to determine possible etiology

A

C, D, E

56
Q

Question 2: A client with pneumonia has a nursing diagnosis of Ineffective Airway Clearance r/t excess mucus and retained secretions. Which of the following would be appropriate nursing interventions? Select all that apply.
• a) Promote fluid intake as appropriate to liquefy secretions
• b) Provide opioid analgesics as ordered to promote comfort
• c) Provide antitussive to relieve cough associated with thick secretions
• d) Provide expectorants as ordered to promote removal of secretions
• e) Teach client effective cough technique to bring secretions to the mouth

A

A, D, E

NOT C because the cough is productive therefore you do not want to suppress it
