Leukemia is a chronic illness and it is expected that the patient will be in and out of the hospital. To maintain communication, the nurse will _________.

Correct Answer: B

Rationale: It is important for the nurse to have a direct and easily accessible means of communication with the patient who is expected to be in and out of the hospital due to their chronic illness like leukemia. By asking for the patient's phone number, the nurse can quickly reach out to them for updates, clarification, or any urgent matters that may arise. This direct communication line helps in ensuring continuity of care and addressing the patient's needs promptly. This approach is more practical and efficient compared to options such as asking the patient to call the hospital number listed in the yellow pages or relying on chart information which may not always be up to date. Writing down the number and giving it to the ward clerk may cause unnecessary delays in communication.

Correct Answer: B

Rationale: The extraneous variable in a study is a variable that is not the main focus of the study but could potentially impact the results. In this case, the length of stay is an extraneous variable because it is not directly related to the research question or objective of the study. The study is likely focused on factors such as patient age, complications, or date of admission, making the length of stay an irrelevant variable in this context.

Correct Answer: B

Rationale: Ella's statement "I will hang myself" directly indicates a desire and intent to commit suicide. This is classified as a suicidal intent, which is a serious concern that requires immediate attention and intervention. It is crucial to take any mention or indication of suicide seriously and seek help from mental health professionals or crisis intervention services.

Correct Answer: D

Rationale: Alzheimer's disease is the most common form of dementia. Dementia is a general term for a decline in mental ability that becomes severe enough to interfere with daily life. It can affect memory, thinking skills, and the ability to perform everyday tasks. Alzheimer's disease specifically is a progressive brain disorder that slowly destroys memory and thinking skills and eventually impairs the ability to carry out simple tasks. Therefore, the provided condition of having difficulty in processing stimuli and new information aligns with the symptoms commonly seen in individuals with Alzheimer's disease.

Correct Answer: B

Rationale: Cardiogenic shock is a life-threatening condition where the heart is unable to pump enough blood to meet the body's demands. Monitoring the patient's cardiac index, which is a measure of cardiac output adjusted for body surface area, can help detect the risk of developing cardiogenic shock. A decrease in cardiac index would indicate a decrease in the heart's ability to effectively pump blood, putting the patient at risk for cardiogenic shock. Monitoring cardiac index is essential in assessing cardiac function and guiding interventions to prevent the progression to cardiogenic shock. The other factors listed may provide important information in assessing the patient's condition, but specifically in detecting the risk of developing cardiogenic shock, monitoring the cardiac index is crucial.
