The nurse is assisting with a patient being intubated at the bedside. After endotracheal tube insertion and the cuff inflation, what are the next appropriate actions to confirm placement before securing the airway? Select all that apply.

Administer a sedative and paralytic agent.

Order a chest x-ray.

Use an end-tidal CO2 detector.

Auscultate for bilateral breath sounds.

Obtain ABGs.

Answer and Explanation

Correct Answer : B,C,D

Choice A rationale

Administering sedative or paralytic agents is typically performed prior to or during the actual intubation process to facilitate tube passage and prevent airway trauma. Once the tube is inserted and the cuff is inflated, the priority shifts to verification of placement rather than further sedation. Giving these drugs after insertion does not provide any diagnostic data regarding whether the tube is in the trachea or the esophagus.

Choice B rationale

A chest x-ray is the definitive gold standard for confirming the depth of endotracheal tube placement. It ensures the distal tip of the tube is positioned approximately 2 to 5 cm above the carina. While other methods confirm the tube is in the trachea, the x-ray is essential to ensure it has not migrated into the right mainstem bronchus, which would cause unilateral lung expansion and potential collapse.

Choice C rationale

End-tidal carbon dioxide detection provides immediate physiological feedback that the tube is located within the respiratory tract. Since CO2 is a byproduct of alveolar gas exchange, its presence in exhaled air indicates the tube is in the trachea rather than the esophagus. A colorimetric changer or capnography waveform is a primary tool used immediately after intubation to rule out esophageal placement before further interventions are performed.

Choice D rationale

Auscultation is a critical immediate step to verify bilateral lung expansion and rule out unintentional esophageal or endobronchial intubation. The nurse should listen for equal breath sounds over the midaxillary lines and ensure there are no gurgling sounds over the epigastrium. Epigastric sounds suggest the tube is in the stomach. Breath sounds must be assessed early to ensure both lungs are being ventilated prior to securing the device.

Choice E rationale

Arterial blood gases are useful for evaluating the long-term effectiveness of ventilation and oxygenation after the patient is stabilized on a ventilator. However, they are not used for the initial confirmation of tube placement because the results take too long to obtain. Verification must be instantaneous using physical assessment and CO2 detection to prevent hypoxia. Normal pH is 7.35 to 7.45, and normal PaO2 is 80 to 100 mmHg.

Correct Answer is A

Explanation

Choice A rationale

Following resuscitation from cardiac arrest, assessing the neurological status by checking the ability to follow commands is the priority. This determines the presence of anoxic brain injury and guides the decision for targeted temperature management. If a patient is unable to follow commands, induced hypothermia is indicated to protect cerebral function. This assessment takes precedence as it dictates immediate, time sensitive neuroprotective interventions that significantly impact the long term functional recovery and survival of the patient.

Choice B rationale

Assessing for chest pain is important in identifying an acute myocardial infarction as the underlying cause of the arrest. However, many post arrest patients are intubated, sedated, or have altered consciousness, making subjective pain reports unreliable. While an electrocardiogram would be performed to check for ST segment elevation, the immediate physiological priority post transfer is neurological assessment to determine the need for therapeutic hypothermia, which must be initiated rapidly to be effective for brain preservation.

Choice C rationale

Auscultating breath sounds is a vital part of the secondary assessment to ensure proper endotracheal tube placement and bilateral lung expansion. While airway and breathing are fundamental, in the immediate seconds following ICU transfer after successful resuscitation, the decision tree pivots toward neurological protection. Ensuring the ventilator is functioning is routine, but the specific ICU priority for "best outcome" centers on identifying candidates for specialized protocols like cooling to mitigate reperfusion injury in the brain.

Choice D rationale

Signs of shock, such as cool, clammy skin or delayed capillary refill, indicate poor systemic perfusion and low cardiac output. Hemodynamic monitoring via blood pressure and central venous pressure is standard in the post arrest period. However, hemodynamic stabilization usually occurs during the initial resuscitation phase. Once in the ICU, the focus shifts to the subtle assessment of neurologic recovery to determine if the patient requires advanced neuroprotective bundles to prevent permanent cognitive and motor deficits.

A. Ativan 1 mg intravenous bolus now. B. Albumin 20 C. Furosemide 40 mg intravenous bolus now. D. Digoxin 0.25 mg intravenous bolus now.

Correct Answer is C

Explanation

Choice A rationale

Ativan is a benzodiazepine used primarily for sedation or to treat anxiety and seizures. It has no direct effect on reducing central venous pressure or managing fluid volume overload. A central venous pressure of 15 mmHg is elevated, as the normal range is typically 2 to 8 mmHg. Administering a sedative would not address the physiological issue of excess preload or right-sided heart congestion indicated by the high pressure reading in this patient.

Choice B rationale

Albumin is a colloid used to expand intravascular volume by pulling fluid from the interstitial space into the vessels. Administering albumin would increase the central venous pressure further, which is dangerous in a patient who already shows signs of volume excess with a reading of 15 mmHg. This would worsen the strain on the heart and potentially lead to pulmonary edema. Normal range for central venous pressure is 2 to 8 mmHg.

Choice C rationale

Furosemide is a potent loop diuretic that increases the excretion of sodium and water by the kidneys. It is the appropriate treatment for a central venous pressure of 15 mmHg, which indicates fluid volume overload or right heart failure since the normal range is 2 to 8 mmHg. By inducing diuresis, furosemide reduces the total circulating blood volume and lowers the preload, thereby decreasing the central venous pressure and relieving the workload on the heart.

Choice D rationale

Digoxin is an inotropic agent used to increase the force of myocardial contraction and slow the heart rate in conditions like atrial fibrillation. While it can help with heart failure, it is not the first-line medication for an acute elevation in central venous pressure caused by volume overload. Diuresis is a more direct and faster way to lower the pressure reading of 15 mmHg back toward the normal range of 2 to 8 mmHg.
