Adult Health Med Surg Nursing Test Banks

Correct Answer: C

Rationale: A living will is a legal document that outlines a person's preferences and wishes regarding medical treatment, including resuscitation, in the event they become unable to communicate or make decisions. In this scenario, the client being admitted to the oncology unit wants to convey his wishes regarding resuscitation in case of cardiopulmonary arrest. A living will helps ensure that these wishes are known and respected by healthcare providers and loved ones. While a will addresses how a person's assets should be distributed after death and a health care power of attorney designates someone to make medical decisions on the person's behalf, a living will specifically focuses on healthcare preferences and treatment decisions. A proxy directive is similar to a health care power of attorney, designating someone to make healthcare decisions for the person if they are unable to do so themselves.

Correct Answer: D

Rationale: Thrombocytopenia is a condition characterized by a low platelet count, which can lead to an increased risk of bleeding. Patients with thrombocytopenia are at risk for injury due to potential bleeding complications. Therefore, the appropriate nursing diagnosis to protect the patient from further injury in this case would be "Risk for injury related to thrombocytopenia." This nursing diagnosis allows the nurse to assess for signs of bleeding, implement interventions to prevent injury, and closely monitor the patient's platelet levels to prevent complications.

Correct Answer: C

Rationale: The patient's presentation of swelling of the ankles, dyspnea on exertion, and orthopnea is highly suggestive of heart failure. The echocardiogram findings of decreased left ventricular ejection fraction and dilated left ventricle are characteristic of heart failure with reduced ejection fraction (HFrEF), also known as systolic heart failure. In this condition, the heart's ability to pump blood effectively is compromised, leading to symptoms of congestion and decreased cardiac output. The decreased ejection fraction indicates that the heart is not able to efficiently pump out blood with each contraction. Dilatation of the left ventricle is a compensatory mechanism in response to increased volume overload.

Correct Answer: A

Rationale: Immunological memory is primarily maintained by the clonal expansion of memory B cells. Memory B cells are a type of long-lived immune cell that originates from previously activated B cells during an immune response to a pathogen. When the immune system encounters the same pathogen again, memory B cells can quickly recognize and respond to it by undergoing rapid clonal expansion and differentiation into plasma cells that produce specific antibodies. This quick and robust response leads to the more efficient elimination of the pathogen during secondary exposure, resulting in the faster and stronger immune response characteristic of immunological memory.

Correct Answer: B

Rationale: The correct charting rule to keep the nurse legally safe is to document worries and all concerns as verbalized by the patient (Choice I). This is important for accurately reflecting the patient's condition, communication, and potential interventions. Charting at the end of the shift only (Choice II) is not recommended as it can lead to missed important details or delayed documentation. Discussing recorded cases and diagnoses of the patient (Choice III) breaches patient confidentiality and violates HIPAA laws. Recording all information verbalized by the patient and family (Choice IV) may include unnecessary details and could potentially lead to misinterpretation or misunderstanding, which might not be legally advantageous.
