Question

A client is recovering from acute respiratory distress syndrome (ARDS). The nurse determines that the client's condition is improved upon reading which entry in the medical record?

Laboratory Test	Normal Findings (Conventional Units)
Pa02	80-95 mmHg

Normal Pa02 range: 80-95 mmHg

Answer 1

Correct Answers:

Pa02 80 mmHg, no infiltrates on chest x-ray

Rationale :

💠 ARDS improves when oxygenation and lung imaging improve, reflecting resolving alveolar-capillary damage.

💠 A PaO₂ of 80 mmHg is within the normal range (80–95 mmHg), showing adequate oxygen exchange.

💠 No infiltrates on chest x-ray suggests the prior diffuse inflammatory fluid/atelectasis is resolving.

💠 Together, normal PaO₂ + cleared infiltrates indicates improved ventilation–perfusion matching and alveolar recruitment.

💠 This is the best record entry showing clinical recovery, compared with persistent atelectasis or “white-out” findings.

💠 PaO₂ 88 mmHg, bibasilar atelectasis on chest x-ray

💠 Bibasilar atelectasis means there is still alveolar collapse, which can impair gas exchange.

💠 Even with a normal PaO₂, the x-ray finding suggests incomplete pulmonary recovery.

PaO₂ 68 mmHg, bilateral white-outs on chest x-ray

💠 A PaO₂ of 68 mmHg indicates hypoxemia, which is not improvement in ARDS.

💠 Bilateral white-outs reflect severe diffuse lung involvement typical of worsening/active ARDS.

PaO₂ 75 mmHg, left-sided white-out on chest x-ray

💠 PaO₂ 75 mmHg is below normal, showing ongoing oxygenation impairment.

💠 A white-out still indicates significant alveolar filling/collapse, not recovery.

Answer 2

Correct Answers:

Flumazenil

Rationale :

💠 Midazolam is a benzodiazepine, which can cause CNS depression and respiratory depression when excessive.

💠 The client’s RR 8/min and SpO₂ 85% indicate dangerous hypoventilation requiring rapid reversal/support.

💠 Flumazenil is a benzodiazepine antagonist that reverses sedation by blocking benzodiazepine receptors.

💠 Reversal can improve level of consciousness and respiratory drive when benzodiazepines are the cause.

💠 The nurse should also anticipate close monitoring because flumazenil may wear off before the sedative does.

Epinephrine

💠 Epinephrine is used for anaphylaxis/cardiac arrest/severe bronchospasm, not benzodiazepine reversal.

💠 It does not directly reverse midazolam-induced CNS depression.

Naloxone

💠 Naloxone reverses opioids, not benzodiazepines.

💠 It will not reliably correct sedation caused by midazolam.

Atropine

💠 Atropine treats symptomatic bradycardia and some cholinergic states.

💠 It does not reverse sedative-hypnotic respiratory depression from benzodiazepines.

Answer 3

Correct Answers:

Chest tube clamps, sterile occlusive dressing, and bottle of sterile water

Rationale :

💠 Chest tubes can become disconnected or accidentally pulled, creating risk for air entry and lung collapse.

💠 A sterile occlusive dressing is needed immediately if the system disconnects to prevent air from being sucked into the pleural space.

💠 A bottle of sterile water allows quick creation of a temporary water seal if the drainage system is compromised.

💠 Chest tube clamps may be required briefly in emergencies (per facility protocol) to control air leaks or change systems safely.

💠 Having these items at the bedside prepares the nurse for the highest-risk, time-sensitive chest tube complications.

Ambu bag, suction setup, and padded tongue blade

💠 Bag-valve-mask and suction can be helpful generally, but they do not directly manage chest tube disconnection/air leak emergencies.

💠 A padded tongue blade is not a standard emergency priority for chest tube complications.

Sterile gauze, oxygen tubing, and incentive spirometer

💠 These items support oxygenation and postoperative lung expansion, but they are not the key tools to manage sudden chest tube disruption.

💠 Emergency chest tube events require occlusive dressing + water seal readiness.

Yankauer suction, oxygen mask, and warming blanket

💠 These are supportive measures but do not address the immediate pleural safety issue if the chest tube system fails.

💠 Chest tube emergencies center on preventing air entry and maintaining a water seal.

Answer 4

Correct Answers:

Fluid restriction

Rationale :

💠 SIADH causes excess ADH, leading to water retention and dilutional hyponatremia.

💠 The first priority is to stop worsening free-water excess by implementing fluid restriction.

💠 Fluid restriction helps raise serum sodium by reducing dilution and lowering total body water.

💠 This approach targets the primary problem—too much water, not too little sodium intake.

💠 Other therapies are reserved for severe symptoms or dangerously low sodium levels.

Administration of vasopressin

💠 Vasopressin is an ADH analog and would worsen SIADH by increasing water retention.

💠 It can intensify hyponatremia and neurologic risk.

Encourage oral fluid intake

💠 Increasing fluids further dilutes serum sodium and aggravates water overload.

💠 This increases risk for cerebral edema and neurologic deterioration.

Administration of hypertonic saline

💠 Hypertonic saline is used for severe symptomatic hyponatremia (e.g., seizures, profound neuro changes).

💠 It is not typically the first-line measure when the initial goal is controlling water excess.

Answer 5

Correct Answers:

Naloxone

Rationale :

💠 The combination of pinpoint pupils, severe respiratory depression (RR 6/min), and unresponsiveness is classic for opioid toxicity.

💠 Opioids depress the medullary respiratory center, causing hypoventilation, hypoxemia (SpO₂ 82%), and potential respiratory arrest.

💠 Naloxone is an opioid antagonist that rapidly reverses opioid effects at receptor sites.

💠 Reversal improves respiratory drive and oxygenation, which is the immediate life-saving priority.

💠 Ongoing monitoring is essential because naloxone’s duration may be shorter than the opioid’s, creating risk for re-sedation.

Flumazenil

💠 Flumazenil reverses benzodiazepines, not opioids, so it will not treat pinpoint pupils with opioid-type respiratory depression.

💠 It can also increase seizure risk in mixed overdoses, so it is not the expected first antidote here.

Propofol

💠 Propofol is a sedative/anesthetic and can worsen hypotension and respiratory depression in an already unresponsive client.

💠 It is not an antidote and would delay correcting the primary problem—ventilatory failure.

Atropine

💠 Atropine is used for symptomatic bradycardia and certain cholinergic presentations, not opioid overdose.

💠 It does not reverse central respiratory depression, which is the urgent issue here.

Answer 6

Correct Answers:

Confirm the equipment is properly functioning
Hyperoxygenate the client with 100% 02 prior to intubation
Administer sedatives and analgesics as prescribed to ensure client comfort
Secure the endotracheal tube with tape after insertion
Monitor oxygen saturation throughout the procedure
Suction the client's airway to clear any secretions before the procedure

Rationale :

Confirm the equipment is properly functioning

💠 Ensuring the equipment works prevents delays during a time-critical airway procedure.

💠 A functioning laryngoscope, appropriate-size ETT, stylet, suction, and bag-valve-mask supports fast, accurate tube placement.

💠 Equipment failure can prolong apnea time and rapidly worsen hypoxemia.

💠 Proper setup also reduces trauma from repeated attempts and improves first-pass success.

💠 Verifying equipment is a core safety step that supports immediate rescue ventilation if needed.

Hyperoxygenate the client with 100% O₂ prior to intubation

💠Preoxygenation replaces alveolar nitrogen with oxygen, creating an oxygen reserve for the apneic period.

💠 This delays desaturation and reduces risk of severe hypoxemia during laryngoscopy.

💠 It is especially important in critically ill clients who desaturate quickly.

💠 Adequate preoxygenation improves patient safety if multiple intubation attempts are needed.

💠 It supports safer intubation by maintaining oxygenation until the airway is secured.

Administer sedatives and analgesics as prescribed to ensure client comfort

💠 Sedation and analgesia reduce anxiety, pain, and agitation during airway manipulation.

💠 This decreases coughing, gagging, and sympathetic stimulation that can raise heart rate and blood pressure.

💠 A calmer client allows improved visualization and smoother tube placement, improving success.

💠 Appropriate medications also reduce risk of accidental injury from sudden movement.

💠 Following prescribed sedation supports both safety and humane care during the procedure.

Secure the endotracheal tube with tape after insertion

💠 Securing the tube prevents dislodgement, which can cause sudden loss of airway.

💠 Movement of an unsecured tube increases the risk for right mainstem intubation or accidental extubation.

💠 Proper fixation maintains consistent ventilation and oxygenation after placement.

💠 It also reduces aspiration risk by helping keep the cuff and tube positioned correctly.

💠 Securement is essential for safe transport, repositioning, and ongoing care.

Monitor oxygen saturation throughout the procedure

💠 Continuous SpO₂ monitoring provides real-time detection of hypoxemia.

💠 If saturation drops, the nurse can immediately support ventilation, pause attempts, and re-oxygenate.

💠 This reduces risk of cardiac dysrhythmias and neurologic injury from low oxygen.

💠 Monitoring also helps evaluate whether preoxygenation and ventilation are effective.

💠 It is a critical safety measure throughout airway management.

Suction the client's airway to clear any secretions before the procedure

💠 Removing secretions improves visualization of the vocal cords and airway structures.

💠 Clearing mucus reduces aspiration risk during airway manipulation.

💠 It also reduces obstruction that could impede ventilation and oxygen delivery.

💠 Effective suctioning supports faster, safer tube placement with fewer attempts.

💠 A clear airway decreases complications and promotes successful intubation.

Place the client in a supine position

💠 Simply placing a client supine is not the safest positioning goal because it can worsen airway alignment and raise aspiration risk in some clients.

💠 Intubation safety focuses on optimal airway positioning (head/neck alignment) rather than flat supine placement alone.

Answer 7

Correct Answers:

Ensure a tracheostomy tray is available at the client's bedside.

Rationale :

💠 After thyroidectomy, the most urgent risk is airway compromise from neck hematoma, edema, or laryngeal nerve-related swelling.

💠 Airway obstruction can develop quickly and may require emergent airway access if swelling compresses the trachea.

💠 Keeping a tracheostomy tray at the bedside ensures immediate readiness for a rapidly deteriorating airway.

💠 This intervention directly supports the ABC priority: maintaining a patent airway.

💠 Early preparation reduces time to intervention and lowers the risk of catastrophic hypoxia.

Monitor blood pressure frequently to detect postoperative bleeding

💠 BP changes can be late and nonspecific; airway compromise may occur before significant vital sign changes.

💠 The immediate respiratory threat is mechanical airway obstruction, not blood pressure trends.

Encourage the client to ambulate to reduce the risk of deep vein thrombosis

💠 Ambulation is beneficial, but it does not address the immediate risk of airway swelling/hematoma.

💠 Airway safety is prioritized over mobility in the early postoperative period after thyroid surgery.

Administer a calcium supplement to prevent hypocalcemia

💠 Hypocalcemia is monitored and treated based on symptoms/labs, but it is not the primary immediate airway intervention.

💠 Calcium does not prevent sudden airway compromise from bleeding or edema.

Answer 8

Correct Answers:

There is a kink or obstruction in the chest tube

Rationale :

💠 Normal tidaling reflects pressure changes in the pleural space during inspiration and expiration.

💠 When tidaling stops, a common cause is mechanical blockage such as a kink, dependent loop, clot, or obstruction preventing air/fluid movement.

💠 Obstruction can prevent effective drainage and increase the risk for retained air/fluid and impaired lung re-expansion.

💠 The nurse should first assess the tubing for kinks, dependent loops, and ensure connections are intact and below chest level.

💠 If blockage is suspected, prompt correction restores system function and helps prevent complications like pneumothorax.

The client is experiencing respiratory distress

💠 Respiratory distress may occur with chest tube problems, but it does not specifically explain loss of tidaling in the chamber.

💠 Tidaling is a system-mechanics finding most directly linked to tube patency or lung re-expansion changes.

The suction control chamber is set too low

💠 Suction level affects the amount of negative pressure applied, but it does not typically eliminate tidaling if the tube is patent.

💠 Lack of tidaling is more consistent with obstruction or a fully re-expanded lung rather than low suction alone.

The chest tube needs to be removed immediately

💠 Removal is not an immediate nursing response to absent tidaling and requires a provider order and clinical criteria.

💠 The first step is to assess for kinks/occlusion and evaluate the system and patient status.

Answer 9

Correct Answers:

Adrenal insufficiency

Rationale :

💠 Pasireotide is a somatostatin analog that reduces ACTH secretion, lowering cortisol production in Cushing’s disease.

💠 If cortisol falls too much, the client can develop adrenal insufficiency, which is a high-risk complication.

💠 Adrenal insufficiency may present with severe fatigue, weakness, hypotension, nausea/vomiting, and can progress to adrenal crisis.

💠 Early recognition is essential because inadequate cortisol impairs the stress response and can cause rapid clinical decline.

💠 The nurse should teach the client to report symptoms promptly and follow provider guidance regarding monitoring and dose adjustments.

Hypokalemia

💠 Hypokalemia is more strongly associated with excess cortisol/mineralocorticoid effects in uncontrolled Cushing’s rather than being the main teaching focus for pasireotide.

💠 While electrolytes are monitored, the priority education point with therapy lowering cortisol is too little cortisol.

Hypernatremia

💠 Hypernatremia is not the primary expected adverse effect to monitor closely with pasireotide in this context.

💠 The more urgent concern is suppression of cortisol leading to adrenal insufficiency symptoms.

Fluid overload

💠 Fluid overload is not the key adverse effect expected from pasireotide therapy.

💠 The clinically significant risk when lowering ACTH/cortisol is adrenal insufficiency, not volume excess.

Answer 10

Correct Answers:

Contact the provider for an order for fentanyl continuous infusion.

Rationale :

💠 A client receiving a paralytic cannot communicate pain, so tachycardia (HR 109) can be a key sign of inadequate analgesia.

💠 In ARDS (especially prone), the plan of care should ensure analgesia-first sedation to reduce stress response and ventilator dyssynchrony.

💠 Fentanyl infusion provides consistent pain control, which helps stabilize HR and improves comfort while mechanically ventilated.

💠 Adequate analgesia also reduces catecholamine surges that can worsen oxygen demand and hemodynamic strain.

💠 Adding a continuous opioid is appropriate because the client is already on continuous sedation/paralytic and needs continuous pain coverage.

Add lorazepam every 2 hours IV push scheduled around the clock.

💠 Intermittent benzodiazepine boluses can cause over-sedation, prolonged ventilation, and delirium risk without addressing pain directly.

💠 The finding points more toward analgesia needs than adding scheduled sedative pushes.

Decrease the client's sedation to maintain a RASS score of 2.

💠 A RASS of +2 indicates agitation, which is not a target for a paralyzed, ventilated ARDS client.

💠 With paralytics, sedation should be adequate (often deeper targets) to prevent awareness and distress.

Decrease the frequency of oral care performed on the client.

💠 Oral care is essential to reduce ventilator-associated pneumonia (VAP) risk.

💠 Decreasing it increases infection risk and does not address tachycardia or comfort.
