A client with coronary artery disease (CAD) is admitted to the medical unit for testing. The client describes having had frequent episodes of angina over the last few days prior to admission. The client is now experiencing shortness of breath, nausea, and chest pressure. After obtaining the client's vital signs, which action should the nurse take next?
Verify troponin level assessments are scheduled every 3 to 6 hours for a series of three.
Initiate dim lighting, lower alarm volumes, and control traffic in and out of the room area.
Count and record the number of premature ventricular contractions per minute.
Apply oxygen via nasal cannula and titrate to keep oxygen saturation above 93%.
The Correct Answer is D
Rationale
A. Troponin levels are cardiac biomarkers that are elevated in the blood when there is damage to the heart muscle, such as during a myocardial infarction (heart attack). Verifying the schedule for troponin assessments is important to monitor for myocardial damage and to guide treatment decisions.
B. This action is aimed at creating a quiet and calm environment for the client, which can help reduce anxiety and minimize stimuli that might exacerbate symptoms. Creating a conducive environment is beneficial for the client's comfort and well-being but should not delay urgent interventions required for acute symptoms.
C. PVCs are abnormal heartbeats that can occur in individuals with CAD and may indicate increased cardiac irritability or instability. While monitoring PVCs is important for assessing cardiac rhythm and potential complications, it is not the immediate priority over addressing acute symptoms such as shortness of breath, nausea, and chest pressure.
D. Oxygen therapy is essential in the management of a client with suspected ACS to improve oxygenation and reduce cardiac workload. Maintaining oxygen saturation above 93% helps ensure adequate tissue oxygenation, especially during episodes of chest discomfort and potential myocardial ischemia.

Correct Answer is A
Explanation
Rationale
A. The client's pH is low (acidotic), and the PaCO2 is high (respiratory acidosis). Increasing the rate of ventilation (respiratory rate) can help to decrease PaCO2 by increasing alveolar ventilation, thereby helping to correct respiratory acidosis.
B. Expiratory flow time affects the time available for exhalation. While this may affect the overall mechanics of ventilation, it is not directly targeting the primary issue of elevated PaCO2 and acidosis.
C. Increasing tidal volume increases the volume of air delivered with each breath. This can improve ventilation efficiency but may not address the underlying problem of elevated PaCO2 unless it leads to increased minute ventilation.
D. Expiratory pressure is related to positive end-expiratory pressure (PEEP), which helps maintain alveolar recruitment and improve oxygenation. Decreasing expiratory pressure may not directly address the elevated PaCO2 and acidosis.
Correct Answer is ["B","E","F"]
Explanation
B. This statement suggests a misunderstanding or stigma associated with mental health diagnoses. It's important for the nurse to clarify that experiencing acute stress disorder or any other psychological response to trauma does not equate to being "crazy." This can help reduce stigma and promote understanding that such responses are normal reactions to abnormal situations.
E. This statement indicates a potential misunderstanding about the duration of medication use. Clonazepam, in this case, is prescribed to manage acute symptoms related to anxiety and sleep disturbance. The nurse should explain that medication use for psychological symptoms is typically temporary and part of a broader treatment plan that may include therapy and other interventions aimed at recovery and long-term well-being.
F. While acute stress disorder is a risk factor for developing post-traumatic stress disorder (PTSD), not everyone who experiences acute stress disorder will develop PTSD. It's important for the nurse to provide education about the differences between acute stress disorder and PTSD, their symptoms, and the importance of ongoing monitoring and support to prevent long-term psychological difficulties.
