Nursing a Concept Based Approach to Learning Test Bank Free

Correct Answer: B

Rationale: Option B, washing the lower extremities with mild soap, drying the legs, and applying a light moisturizer, indicates effective teaching for a client with peripheral vascular disease (PVD). Proper hygiene, including gentle washing with mild soap, thorough drying to prevent moisture-related skin breakdown, and moisturizing to prevent dry skin and promote circulation, are key components of self-care for individuals with PVD. Option A is incorrect because sitting with a pillow behind the knees does not specifically address PVD self-care. Option C is incorrect because crossing the left leg over the right while sitting does not relate to appropriate PVD management. Option D is incorrect because smoking in any form is detrimental to vascular health and should be discouraged in PVD management.

Correct Answer: C

Rationale: The highest priority when caring for a patient with manifestations of appendicitis is to provide pain relief. By inserting a saline lock for intravenous pain medication, the patient can receive immediate pain relief to alleviate their discomfort. Pain management is crucial in appendicitis as it can help in improving the patient's overall well-being and reduce the risk of complications. While other options such as withholding food and fluids, performing preoperative skin preparation, or teaching postoperative exercises are important aspects of care, addressing the patient's pain is the top priority to ensure their comfort and well-being.

Correct Answer: C

Rationale: When the nurse asks the patient to move an extremity away from the body midline, they are assessing the movement of abduction. Abduction refers to the movement of a body part away from the midline of the body. In this case, moving the extremity away from the body midline represents abduction, as the limb is being moved outward or away from the center of the body. Flexion and extension involve bending and straightening movements, respectively, along a joint axis, while adduction involves moving a body part towards the midline of the body.

Correct Answer: C

Rationale: After an embolus becomes trapped in the pulmonary microvasculature, dead space increases. Dead space refers to the portion of the lung that is ventilated but not perfused, resulting in reduced gas exchange. When a pulmonary embolus blocks blood flow within a pulmonary vessel, it leads to a mismatch between ventilation and perfusion in the affected lung region. This mismatch results in increased dead space, as ventilation continues in areas that are not effectively perfused. As dead space increases, the overall efficiency of gas exchange in the lung is impaired, potentially leading to hypoxemia.

Correct Answer: B

Rationale: The client with cardiomyopathy may experience decreased cardiac output, which is a common manifestation of this condition. Cardiomyopathy is a disease of the heart muscle that makes it harder for the heart to pump blood to the rest of the body. Reduced cardiac output means that less blood is being pumped out by the heart with each beat, leading to symptoms such as fatigue, weakness, and the need to rest between activities. This is why the client is experiencing the need to rest between activities during the day.
