Question 1
Regular
A nurse answers a call light and finds a client anxious, short of breath, reporting chest pain, and having a blood pressure of 88/52 mm Hg. What action by the nurse is best?
Correct!
Incorrect
The correct answer is: C
Rationale
Prepare to administer thrombolytic therapy. Given the client's symptoms of chest pain, anxiety, and low blood pressure, thrombolytics are critical to address a potential myocardial infarction urgently.
A: Administer oxygen at 2 L/min via nasal cannula. While oxygen can relieve hypoxia, it does not address the underlying cause of the client’s severe symptoms requiring immediate thrombolytic therapy.
B: Obtain a STAT chest X-ray. A chest X-ray may provide diagnostic information, but it does not offer immediate treatment for the potentially life-threatening condition indicated by the client’s symptoms.
D: Monitor the client's blood pressure every 15 minutes. Frequent blood pressure monitoring is important, yet it fails to provide timely intervention for the acute situation, which necessitates prompt thrombolytic therapy.

Question 2
Regular
A client is on intravenous heparin to treat a pulmonary embolism. The client's most recent partial thromboplastin time (PTT) was 25 seconds. What order should the nurse anticipate?
Correct!
Incorrect
The correct answer is: B
Rationale
Increase the heparin rate.
The client's partial thromboplastin time (PTT) of 25 seconds indicates insufficient anticoagulation for treating a pulmonary embolism. Anticipating an increase in the heparin rate is essential to achieve the therapeutic range, which is typically higher, ensuring effective treatment and reducing the risk of further complications.
A: Decrease the heparin rate. Lowering the heparin rate would exacerbate the risk of clot formation, leaving the client vulnerable to further embolic events.
C: Maintain the heparin rate. Keeping the heparin rate unchanged fails to address the critically low PTT, which does not provide adequate anticoagulation for the client's condition.
D: Administer protamine sulfate. Administering protamine sulfate is an inappropriate response as it counteracts heparin's effects, which is not warranted when the PTT indicates insufficient anticoagulation.

A: Avoid drinking alcohol Excessive alcohol consumption can exacerbate the risk factors associated with hormonal birth control, but it does not directly relate to pulmonary embolism prevention.
B: Eat more omega-3 fatty acids While omega-3 fatty acids have cardiovascular benefits, their consumption alone does not significantly influence the risk of pulmonary embolism in women using hormonal birth control.
Question 22
Multiple Choice
A client with a new pulmonary embolism (PE) is anxious. What nursing actions are most appropriate? (Select all that apply.)
Correct!
Incorrect
The correct answer is: A,B,C,E
Rationale
Acknowledge the frightening nature of the illness, give simple explanations of what is happening, and stay with the client and speak in a quiet, calm voice are the most appropriate actions.
Acknowledging the illness helps validate the client's feelings, while simple explanations reduce fear through understanding. Staying with the client provides reassurance, fostering a supportive environment during a distressing experience.
B: Delegate a back rub to the unlicensed assistive personnel. This action does not directly address the client's anxiety or emotional needs, which are crucial in managing their distress.
D: Request a prescription for anti-anxiety medication. This response may not be immediately appropriate, as non-pharmacological interventions should be prioritized to alleviate anxiety and establish rapport first.

Question 23
Multiple Choice
The nurse caring for mechanically ventilated clients uses best practices to prevent ventilator-associated pneumonia. What actions are included in this practice? (Select all that apply.)
Correct!
Incorrect
The correct answer is: A,B,C,D
Rationale
Adherence to proper hand hygiene, administering anti-ulcer medication, elevating the head of the bed, and providing oral care per protocol are essential actions in preventing ventilator-associated pneumonia. These practices reduce infection risk by maintaining a sterile environment, preventing gastric reflux, enhancing pulmonary function, and ensuring oral hygiene, all critical for mechanically ventilated patients' safety and health.
E: Suctioning the client on a regular schedule does not align with best practices, as unnecessary suctioning can increase respiratory complications and disrupt the airway, leading to potential harm.

Question 24
Multiple Choice
A nurse is caring for a client who is on mechanical ventilation. What actions will promote comfort in this client? (Select all that apply.)
Correct!
Incorrect
The correct answer is: A,B,D,E
Rationale
Allow visitors at the client's bedside, ensure the client can communicate if awake, provide back and hand massages when turning, and turn the client every 2 hours or more promote comfort.
The context emphasizes the importance of emotional support, effective communication, physical comfort, and regular repositioning to enhance the overall well-being of clients on mechanical ventilation, addressing their unique needs comprehensively.
C: Keep the television tuned to a favorite channel. This option focuses on distraction rather than direct comfort measures that involve personal interaction and physical care, which are crucial for the client’s emotional state.

Question 25
Multiple Choice
The nurse caring for mechanically ventilated clients knows that older adults are at higher risk for weaning failure. What age-related changes contribute to this? (Select all that apply.)
Correct!
Incorrect
The correct answer is: A,B,D
Rationale
Older adults experience chest wall stiffness, decreased muscle strength, and less lung elasticity, which collectively impair respiratory mechanics and increase the likelihood of weaning failure during mechanical ventilation.
A: Chest wall stiffness Contributes to reduced lung expansion and impaired ventilation, making it more difficult for older adults to effectively manage their breathing when weaning from mechanical ventilation.
B: Decreased muscle strength Diminished muscle strength compromises the ability to generate sufficient respiratory effort, hindering effective weaning from mechanical ventilation and increasing the risk of failure.
C: Inability to cooperate While cooperation is important, it is not primarily an age-related physiological change affecting weaning, unlike the mechanical and muscular factors that are crucial in older adults.
E: Poor vision and hearing Although these senses may affect communication, they do not directly influence the physiological capacity for breathing and weaning from mechanical ventilation in older adults.

Question 26
Regular
A 242-pound client is being mechanically ventilated. To prevent lung injury, what setting should the nurse anticipate for tidal volume? (Record your answer using a whole number.) mL
Correct!
Incorrect
The correct answer is: B
Rationale
A 660 mL tidal volume setting is anticipated for the 242-pound client. This volume aligns with the recommended range of 6-8 mL/kg for mechanical ventilation, minimizing the risk of lung injury.
A: 600 mL This volume may be insufficient for a client of this weight, potentially leading to inadequate ventilation and compromised gas exchange.
C: 700 mL Slightly higher than the recommended range, this volume might increase the risk of barotrauma and other ventilatory complications.
D: 750 mL This volume exceeds the safe limit for tidal volume, significantly elevating the risk of lung injury and adverse ventilation outcomes.
