Q

A nurse is caring for a patient diagnosed with acute respiratory distress syndrome. The nurse is aware that these patients often will require which intervention?

A

Patients with acute respiratory distress syndrome likely will require mechanical ventilation to support their respiratory status. Frequent suctioning is not required often, but some suctioning may be required. Peritoneal dialysis and creatinine and BUN testing might be necessary with some level of kidney failure, not respiratory compromise.`

Q

When caring for the patient with acute respiratory distress syndrome (ARDS), the critical care nurse knows that therapy is appropriate for the patient when which goal is being met?

  • pH is 7.32
  • PaO2 is greater than or equal to 60 mm Hg
  • (PEEP) increased to 20 cm H2O caused blood pressure (BP) to fall to 80/40
  • No change in PaO2 when patient is turned from supine to prone position
A

The overall goal in caring for the patient with ARDS is for the PaO2 to be greater than or equal to 60mm Hg with adequate lung ventilation to maintain a normal pH of 7.35 to 7.45. PEEP usually is increased for ARDS patients, but a dramatic reduction in BP indicates a complication of decreased cardiac output. A positive occurrence is a marked improvement in PaO2 from perfusion better matching ventilation when the anterior air-filled, nonatelectatic alveoli become dependent in the prone position.

Q

The nurse assesses a patient admitted 2 days ago with a diagnosis of chest trauma after a motor vehicle accident. Oxygen is being delivered at 60% by way of Venturi mask. Which assessment finding indicates the development of adult respiratory distress syndrome?

A

One of the main characteristics of adult respiratory distress syndrome (ARDS) is worsening hypoxemia despite increased delivery of higher concentrations of oxygen. An increase in urine specific gravity is not associated with ARDS. Wheezing and stridor and dyspnea may be present and progress to respiratory distress in the patient with ARDS.

Q

Upon reviewing the reports of a patient, the nurse determines that the patient is at risk for hypoxia. Which finding supports the nurse’s conclusion

A

he partial pressure of oxygen of 45 mm Hg or less in arterial blood indicates that the patient has risk of hypoxia due low blood oxygen levels. A ventilation/perfusion ratio of 1:1 is a normal finding and does not indicate that the patient has risk of hypoxia. An inspiratory to expiratory ratio of 1:2 is a normal finding and does not indicate that the patient has respiratory distress or risk of cyanosis. If patient’s partial pressure of carbon dioxide in arterial blood is 30 mm Hg, it indicates that the patient has normal ventilator demand and supply and does not have risk of hypercapnia or hypoxemia.

Test-Taking Tip: You have at least a 25% chance of selecting the correct response in multiple-choice items. If you are uncertain about a question, eliminate the choices that you believe are wrong and then call on your knowledge, skills, and abilities to choose from the remaining responses.

Q

The nurse is providing care for an older adult patient who is experiencing low partial pressure of oxygen in arterial blood (PaO2) as a result of worsening left-sided pneumonia. Which intervention should the nurse use to help the patient mobilize secretions?

A

Augmented coughing and huff coughing techniques may aid the patient in the mobilization of secretions. If positioned side-lying, the patient should be positioned on the right side (good lung down) for improved perfusion and ventilation. Suctioning may be indicated, but always should be performed cautiously because of the risk of hypoxia. NIPPV is inappropriate in the treatment of patients with excessive secretions.

Q

The nurse is monitoring a patient through pulse oximetry. What is monitored through pulse oximetry?

A

Pulse oximetry is a noninvasive method to determine oxygen saturation levels. It may be used intermittently or continuously to assess SpO2. Pulse oximetry cannot be used to assess inspired oxygen concentration, expired oxygen concentration, or venous oxygen saturation. These can be measured through arterial blood gases measurements or pulmonary artery pressure monitoring.

Q

The nurse is caring for a patient with respiratory failure. What information should the nurse include when explaining the disease condition to the family members?

A

Respiratory failure is classified as hypoxemic or hypercapnic. Respiratory failure results when gas exchanging functions are inadequate, i.e., insufficient oxygen is transferred to the blood or inadequate carbon dioxide is removed from the lungs. Although respiratory failure may be secondary to cardiac failure, not all cases of respiratory failure are secondary to cardiac failure. Respiratory failure is not a disease but a symptom of an underlying pathologic condition affecting lung function, oxygen delivery, cardiac output, or the baseline metabolic state.

Q

The nurse is caring for a patient with a shunt due to acute respiratory distress syndrome (ARDS). Which nursing intervention is associated with better symptomatic relief for this patient?

A

Patients with ARDS having a shunt disorder are usually more hypoxemic than patients with ventilation-perfusion (V/Q) mismatch. They often require mechanical ventilation and a high FIO2 in combination to improve gas exchange. Bronchodilators and corticosteroids are not helpful for immediate relief because the patient does not have bronchospasm and inflammation.

Q

A patient has benzodiazepines (lorazepam [Ativan]) and opioids (morphine) ordered to decrease anxiety, agitation, and pain. What are the nursing roles in managing this patient?

A

The nurse has to monitor patients closely for cardiopulmonary depression when giving benzodiazepines such as lorazepam (Ativan) and opioids (morphine). Patients receiving these agents are best managed by following an evidence-based protocol that includes a regular “sedation holiday” for ongoing assessment. Sedative and analgesic agents may have a prolonged effect in critically ill patients, delay weaning from mechanical ventilation, and contribute to increased length of stay. If respirations become depressed, then the dose of morphine has to be reduced.

Q

The nurse understands that one way to assess the degree of impairment in gas exchange is to measure the arterial oxygen/fraction of inspired oxygen (PaO2/FIO2, or P/F) ratio. What is the P/F ratio in acute lung injury (ALI)?

  • Greater than 400
  • Greater than 300
  • Less than 200
  • Between 200 and 300
A

In ALI, the P/F ratio is between 200 and 300. This indicates compromised gas exchange through the alveoli. Under normal circumstances, when PaO2 is 85 to 100 mm Hg and FIO2 is 0.21, the P/F ratio would be greater than 400. The term acute respiratory distress syndrome (ARDS) is used when the P/F ratio is less than 200 (e.g., 80/0.8 = 100) and indicates refractory hypoxemia.

Q

A nurse is caring for a patient diagnosed with acute lung injury who has a PaO2 of 48 mm Hg. Which condition does the nurse expect?

A

Hypoxemia, an inadequate amount of oxygen in the blood, frequently is quantified as a PaO2 of less than 50 mm Hg. If allowed to progress, hypoxemia can result in hypoxia, which is defined as an inadequate amount of oxygen available at the cellular level such that cells experience anaerobic metabolism.

Q

The nurse is caring for an 83-year-old patient and is reviewing laboratory results. The PaO2 is 76 mm Hg. What nursing action is appropriate for this finding?

A

Age affects normal arterial blood gas (ABG) values. Elderly people have a lower PaO2 level, with a decrease in approximately 10 mm Hg per decade. Normal ABG values are ranges for normal, healthy adults. It is important to establish a baseline for the individual because abnormal values become “normal” for some individuals. Notifying either respiratory therapy or the primary health care provider is not necessary at this time. Administering oxygen is not necessary at this time.

Q

Which medication helps to decrease heart rate and improve cardiac output in the patient with respiratory failure and atrial fibrillation?

A

Diltiazem (Cardizem) is a calcium channel blocker and potent vasodilator. It increases the blood flow through the arteries and decreases the heart rate. Calcium channel blockers reduce blood pressure and increase cardiac output. Administration of nitroglycerine (Tridil) decreases pulmonary congestion caused by heart failure. Metaproterenol (Alupent) is a bronchodilator. It improves breathing by relaxing the muscles in the airways. Methylprednisolone (Solu-Medrol) is administered in conjunction with bronchodilators to treat bronchospasm and asthma.

Q

what gas is not absorbed by the lungs and why is it important

A

Normally, nitrogen (which constitutes 79% of the air that is breathed) is not absorbed into the bloodstream. This prevents alveolar collapse. When high concentrations of O2 are given, nitrogen is washed out of the alveoli and replaced with O2 . If airway obstruction occurs, the O2 is absorbed into the bloodstream and the alveoli collapse. This process is called absorption atelectasis.

The factors like platelets and clotting factors should be replaced if deficient. Traumatic interventions such as intramuscular injections or multiple venipunctures should be avoided. Decreasing the fluid intake and providing enteral feedings will not help in minimizing hematological complications.

A

multiple organ dysfunction syndrome

109
Q 
A patient is showing signs of anaphylactic shock from an insect sting. Which primary health care provider's prescription does the nurse implement first?
Epinephrine
Normal Saline IV
Diphenhydramine
Oxygen via nasal cannula
A

Epinephrine. The patient in anaphylaxis experiences bronchial spasm and constriction. The administration of epinephrine is necessary to reverse this process and facilitate an open airway. Although administering normal saline, diphenhydramine, and oxygen are appropriate, they must be done after an airway has been established.

110
Q

What drug causes arterial and venous dilation?

A

Sodium nitroprusside (Nipride). Sodium nitroprusside (Nipride) acts by dilating both the arteries and veins. It is used in the treatment of cardiogenic shock.

111
Q

What drug increases the force of a heartbeat?

A

Dopamine (Intropin) has inotropic activity. It increases the force of the heartbeat and is used in the treatment of cardiogenic shock.

112
Q

What drug is used in septic shock to cause vasoconstriction

A

Vasopressin (Pitressin) is a vasoconstrictor used mainly in the treatment of septic shock.

113
Q

Phenylephrine (Neo-Synephrine) acts by constricting the peripheral nerves and is used in the treatment of neurogenic shock.

114
Q

With shock, enteral feedings should be planned to achieve at least what % of calories per day

A

80%

115
Q

A patient involved in a motor vehicle accident was admitted to the intensive care unit with a closed-head injury. Which clinical manifestation warns the nurse that the patient’s condition is progressing to multiple organ dysfunction syndrome?

Hypotension and dysrhythmias

Urine output less than 400 mL/day

Alteration in level of consciousness

Decreased PaO2 with an increase in FiO2

A

Decreased PaO2 with an increase in FiO2 (refractory hypoxemia) is correct because the lungs are the first organ to show signs of dysfunction and is the main organ affected in multiple organ dysfunction syndrome. Hypotension and dysrhythmias can occur with hypovolemia and hypoxia without progressing to multiple organ dysfunction syndrome. Urine output less than 400 mL/day develops later in the course of multiple organ dysfunction syndrome, when the kidneys become involved. Alteration in level of consciousness is probably already present with the closed head injury, and also can occur with hypoperfusion, microvascular coagulopathy, or cerebral ischemia, and not necessarily progress to multiple organ dysfunction syndrome.

116
Q

What is the main organ affected in MODS

A

lungs

117
Q

The nurse would recognize which clinical manifestation as suggestive of sepsis?

Sudden diuresis unrelated to drug therapy

Hyperglycemia in the absence of diabetes

Respiratory rate of seven breaths per minute

125
Q

what is dobutrex used for in cardiogenic shock

A

Doubutamine is a sympathomimetic medication. When used in therapy with dobutamine, the patient’s heart rate and blood pressure should be continuously monitored, as it may worsen hypotension, requiring the addition of a vasopressor. The infusion should be stopped if tachydysrhythmias develop. The administration through a central line is recommended, as infiltration leads to tissue sloughing. The drug should not be administered with sodium bicarbonate, as it can get deactivated. As dobutamine is not adsorbed in plastic containers, it is not necessary to administer the drug in glass bottles.

A

tachypnea and tachycardia
pale and cool
lower BP than baseline

157

A

Refractory hypoxemia is rare and refers to hypoxemia that cannot be corrected by giving the patient extra oxygen to breathe. It usually develops as the end result of a condition known as acute respiratory distress syndrome, in which breathing becomes extremely difficult.

159

a pt is experiencing hypovolemia what do you give first

A

100% o2, then IV

160
Q

What abnormal findings should the nurse expect to find in early compensatory shock

A

metabolic acidosis and increased serum sodium.

161
Q

A patient with a suspected traumatic brain injury has bloody nasal drainage. What observation should cause the nurse to suspect that this patient has a cerebrospinal fluid (CSF) leak?

A

When drainage containing both CSF and blood is allowed to drip onto a white pad, within a few minutes the blood will coalesce into the center, and a yellowish ring of CSF will encircle the blood, giving a halo effect. The presence of glucose would be unreliable for determining the presence of CSF because blood also contains glucose. Decreased blood pressure and urinary output would not be indicative of a CSF leak.
