A patient had a cardiac catheterization and is now in the recovery area.
What nursing interventions should be included in the plan of care? Select all that apply.

Choice A rationale

Discussing other patients is a violation of the Health Insurance Portability and Accountability Act and does nothing to reduce a patient's stress. In fact, hearing about the medical crises of others can increase a patient's anxiety and sense of vulnerability within the critical care unit. Professional boundaries must be maintained to ensure a therapeutic environment. Stressors in the ICU are often related to a loss of control, which is worsened by unprofessional and distracting conversations.

Choice B rationale

Clocks, calendars, and personal items provide essential sensory input that helps ground the patient in reality. The critical care environment is often devoid of natural time cues, leading to ICU psychosis or delirium. By providing familiar items and orientation tools, the nurse helps maintain the patient's cognitive function and reduces the psychological stress associated with disorientation. This intervention supports the patient's neurological status and helps stabilize the circadian rhythm during a prolonged hospital stay.

Choice C rationale

Adjusting lighting is a non-pharmacological intervention designed to synchronize the patient's biological clock with the external environment. Continuous bright light in the ICU disrupts sleep-wake cycles, leading to sleep deprivation and impaired healing. By dimming lights at night and providing natural light during the day, the nurse promotes restorative sleep. Proper sleep is vital for immune function and psychological resilience, reducing the overall physiological stress response characterized by elevated cortisol levels.

Choice D rationale

Frequent orientation to the date and time during routine nursing care is a standard delirium prevention strategy. Patients in intensive care often lose track of time due to sedation, illness, and the lack of windows. Constant reorientation provides a sense of security and reduces the fear associated with confusion. This cognitive support is a fundamental nursing intervention that addresses the emotional and mental stressors inherent in a high-acuity, technologically dense medical environment.

Choice A rationale

Cardiac catheterization is the gold standard for visualizing the coronary anatomy through fluoroscopy and radiopaque contrast injection. It allows the physician to identify the exact location and severity of atherosclerotic plaques or occlusions. By determining the percentage of narrowing in the vessels, the medical team can decide if the patient requires medical management, stenting, or surgical bypass. This direct visualization provides definitive information regarding the blood supply to the various regions of the heart muscle.

Choice B rationale

While cardiac catheterization can involve a ventriculogram to estimate the ejection fraction and assess wall motion, this is usually a secondary objective. Non-invasive tests like an echocardiogram are typically the first-line tools used to evaluate how efficiently the heart muscle contracts. The primary and most common reason for invasive catheterization remains the assessment of the coronary arteries rather than just muscular function. Ejection fraction reflects the percentage of blood pumped out of the left ventricle.

Choice C rationale

Evaluating the electrical activity of the heart is primarily the role of an electrocardiogram or an electrophysiology study. While catheters are used in electrophysiology studies to map conduction pathways, a standard cardiac catheterization focused on the coronary arteries does not primarily aim to assess arrhythmias. Identifying the heart's electrical rhythm involves measuring millivolts of electrical potential across the cardiac membranes. This is distinct from the hemodynamic and anatomical data collected during a routine coronary angiogram.

Choice D rationale

Cardiovascular response to stress is usually evaluated through non-invasive stress testing, such as a treadmill test or a pharmacological stress test combined with imaging. These tests observe the heart's behavior under increased metabolic demand to detect signs of inducible ischemia. Cardiac catheterization is an invasive procedure typically performed after a stress test has yielded abnormal results or when a patient presents with acute symptoms. It provides a static view of the anatomy rather than a functional stress assessment.
