A client is scheduled to have heart surgery and informs the nurse that she does not want any life saving measures done should there be any complications. Which of the following responses by the nurse is appropriate?

Choice A rationale

Chest compressions are the primary component of cardiopulmonary resuscitation used to maintain perfusion during cardiac arrest. However, when a client has a documented Do Not Resuscitate order, performing compressions violates their legal and ethical right to refuse life-prolonging interventions. The nurse must honor the autonomy of the individual, especially when they have made a deliberate choice regarding their end-of-life care after being diagnosed with a terminal illness in a clinical setting.

Choice B rationale

Rapid response teams are typically summoned when a patient shows signs of clinical deterioration but still has a pulse and is breathing. Their goal is to prevent a full cardiac or respiratory arrest. Since this patient is already pulseless and has a DNR status, calling a rapid response team is inappropriate. The focus of care transitions from rescue to providing a dignified death, making the activation of an emergency response team unnecessary and contrary.

Choice C rationale

Pressing the Code Blue button initiates a full-scale resuscitation effort involving advanced cardiac life support protocols, intubation, and defibrillation. Initiating a code for a patient with a DNR status is a breach of nursing ethics and legal mandates. The nurse must prioritize the documented wishes of the client over hospital emergency protocols. Resuscitation efforts against a patient's known wishes can result in legal consequences and emotional distress for the grieving family members.

Choice D rationale

Honoring a DNR order is a fundamental aspect of providing patient-centered care and respecting self-determination. When a terminal patient experiences cardiac arrest, the nurse's role is to provide comfort and support rather than invasive medical intervention. This involves documenting the time of death, notifying the physician, and supporting the family. Refraining from lifesaving measures ensures that the client’s transition is peaceful and consistent with the healthcare goals they established before the event.

Choice A rationale

Rhonchi are low-pitched, continuous snoring or rattling sounds caused by secretions or obstructions in the larger airways, such as the bronchi. They are often associated with conditions like chronic bronchitis or pneumonia and may clear with coughing. The description of a high-pitched, squeaking sound does not align with the characteristics of rhonchi, which are deeper and suggest the presence of thick mucus in the larger passages rather than narrowed smaller airways.

Choice B rationale

Crackles, also known as rales, are discontinuous, popping or bubbling sounds heard primarily during inspiration. They are caused by the sudden snapping open of small airways or alveoli that contain fluid. This occurs in conditions like heart failure or pulmonary edema. The sounds described in the question are continuous and high-pitched during exhalation, which is the opposite of the brief, non-continuous nature of crackles caused by fluid movement in distal air sacs.

Choice C rationale

Wheezes are high-pitched, continuous musical or squeaking sounds produced by air flowing through narrowed or constricted small airways. In asthma, bronchospasm and inflammation narrow the bronchioles, typically causing these sounds during expiration. The description of high-pitched squeaking during exhalation is the classic clinical presentation of wheezing. This indicates a significant reduction in the diameter of the airway lumen, requiring prompt assessment of the client’s respiratory effort and oxygen saturation levels.

Choice D rationale

Stridor is a harsh, high-pitched, vibrating sound caused by an obstruction in the upper airway, such as the larynx or trachea. It is usually loudest during inspiration and can often be heard without a stethoscope. Stridor is a medical emergency indicating a compromised upper airway. While high-pitched, it is localized to the throat area rather than the lower lung fields and sounds more like gasping or crowing than the squeaking associated with asthmatic wheezing.
