The geriatric nurse recognizes that the bodys homeostatic mechanisms may be compromised in the:

69-year-old with peripheral vascular disease who is visited by home health care weekly.

73-year-old with a history of chronic bronchitis who lives with family.

86-year-old who lost a spouse and is moving into an assisted living facility.

79-year-old with moderate Alzheimer disease who requires assistance with all activities of daily living (ADLs)

Answer and Explanation

The Correct Answer is D

A.   Peripheral vascular disease (PVD) impairs blood flow to the extremities, which can affect the body's ability to regulate temperature, heal wounds, and manage cardiovascular function. Despite having regular home health care, which helps with monitoring and managing the condition, PVD still poses challenges to maintaining homeostasis.
B.   Chronic bronchitis is a type of chronic obstructive pulmonary disease (COPD) that impairs lung function and impacts the body's ability to exchange gases efficiently. This condition can lead to chronic hypoxemia (low oxygen levels) and hypercapnia (elevated carbon dioxide levels), which directly affect homeostasis.
C.   This individual is undergoing significant life changes, including bereavement and relocation, which can affect emotional and physiological well-being. While these stressors can impact overall health, they are less directly related to physiological processes that maintain homeostasis compared to chronic physical conditions.
D.   Alzheimer’s disease leads to significant cognitive decline, which impairs the ability to perform daily activities and manage personal health. This cognitive impairment can result in a reduced ability to recognize and respond to physiological needs, which compromises homeostatic mechanisms. The need for assistance with all ADLs indicates severe functional impairment, making this patient highly vulnerable to disruptions in homeostasis due to their inability to self-manage health and daily activities effectively.

Correct Answer is D

Explanation

A. Reflex tone refers to the neurological response of the body to stimuli and is not directly related to the action or monitoring of anticoagulant therapy. While assessing reflexes might be important for overall patient health, it is not specifically relevant to monitoring the effects of warfarin. Reflex tone does not provide information on the anticoagulation status or risk of bleeding associated with warfarin therapy.
B. Checking the body for bruising helps assess the safety of warfarin therapy and may indicate the need for dosage adjustments or further investigation if bruising is excessive. However, while monitoring for bruising is essential, it is not the primary method for assessing the effectiveness and safety of anticoagulant therapy.
C. While monitoring kidney function is relevant for overall medication management, it is not the primary focus for directly assessing the effectiveness or safety of warfarin therapy. Kidney function is more related to adjusting doses and avoiding potential complications.
D. Regularly reviewing PT is crucial for managing warfarin therapy because it directly reflects the anticoagulation effect of the medication. The International Normalized Ratio (INR), derived from PT, is used to ensure the patient is within the therapeutic range for effective anticoagulation while minimizing the risk of bleeding.

A. 0.75 tablet B. 1 tablet C. 0.5 tablet D. 0.25 tablet

Correct Answer is C

Explanation

Number of tablets = Desired dose (mg) / Tablet strength (mg) Plugging in the given values:

Number of tablets = 0.125 mg / 0.25 mg/tablet Number of tablets = 0.5 tablet

Therefore, the nurse should prepare 0.5 tablet of digoxin to administer to the patient.
