Case study 71-73
A client was admitted with a diagnosis of respiratory failure 3 weeks ago. She required an artificial airway (tracheostomy) to help clear secretions. The previous shift nurse reports that the client had a very restless night with a drop in O2 saturation level several times despite O2 being set at 40% via trach collar. The previous shift nurse also reports that the client experienced tachycardia and tachypnea during the night.
The nurse immediately checks on the client and finds that she appears anxious with these vital signs:
Blood pressure: 130/90 mm Hg Heart rate: 116 (sinus tachycardia) Respiratory rate: 24 and labored Temperature: 99.6° F (axillary) O2 saturation: 91% on 40% O2 via trach collar
Which finding(s) requires nursing intervention? Select all that apply.
Blood pressure: 130/90 mm Hg
Heart rate: 116 (sinus tachycardia)
Respiratory rate: 24 and labored
Temperature: 99.6° F (axillary)
O2 saturation: 91% on 40% O2 via trach collar
Correct Answer : B,C,E
A. This value is slightly elevated but within a range that does not indicate immediate compromise. It may reflect anxiety or a mild stress response.
B. Tachycardia in this context suggests physiologic stress and compensatory response to hypoxia, anxiety, or early respiratory compromise, requiring intervention and monitoring.
C. A respiratory rate above 20 with labored breathing indicates increased work of breathing and potential respiratory distress, which requires immediate nursing assessment and intervention.
D. This is a low-grade elevation and does not require immediate action in this context. It may reflect mild inflammation or recent activity, not an acute threat.
E. Oxygen saturation below 92% on supplemental oxygen indicates inadequate oxygenation, which requires prompt intervention such as assessing airway patency, suctioning secretions, adjusting oxygen delivery, or notifying the healthcare provider.

Correct Answer is A
Explanation
A. Septicis correct because an abscessed tooth is a localized bacterial infection. If untreated, bacteria can enter the bloodstream and lead to systemic infection and sepsis. Sepsis can progress to septic shock, which is characterized by widespread vasodilation, increased capillary permeability, hypotension, and poor tissue perfusion. A dental abscess is a known source of bacteremia and systemic infection.
B. Obstructiveis incorrect because obstructive shock occurs when there is a physical obstruction to blood flow, such as in pulmonary embolism, cardiac tamponade, or tension pneumothorax. An abscessed tooth does not cause mechanical obstruction of circulation.
C. Cardiogenicis incorrect because cardiogenic shock results from the heart’s inability to pump effectively, often due to myocardial infarction or severe heart failure. There is no indication of cardiac pump failure related to a dental abscess.
D. Hypovolemicis incorrect because hypovolemic shock occurs due to significant blood or fluid loss, such as hemorrhage, vomiting, diarrhea, or burns. An abscess does not directly cause volume depletion.
Correct Answer is C
Explanation
A. Continuous bubbling in a suction chest tube can indicate an air leak. In a properly functioning wet suction system, intermittent bubbling is normal in the water seal chamber, but bubbling in the suction chamber itself is not always required. Monitoring for air leaks is important, but the presence of suction bubbling is not the primary focus for patient care monitoring.
B. Suction levels are prescribed by the healthcare providerand should not be increased based on decreased drainage. Drainage may decrease naturally as the pneumothorax resolves. Changing suction settings independently can cause lung trauma or excessive negative pressure.
C. Monitoring drainage amount and coloris a primary nursing responsibility. It provides information about ongoing bleeding, air leaks, or resolution of the pneumothorax. Sudden increases or changes in drainage can indicate complicationsthat require prompt intervention.
D. Chest tube removal is not time-dependent; it is based on clinical assessment, radiographic evidence of lung re-expansion, and absence of significant air leaks or drainage. Premature removal could lead to recurrence of the pneumothorax.
