Nursing a Concept Based Approach to Learning Test Bank Free

Correct Answer: C

Rationale: Swelling in one leg with edema is a classic sign of deep venous thrombosis (DVT). DVT occurs when a blood clot forms in one or more of the deep veins in the body, usually in the legs. This can lead to swelling in the affected leg due to the impaired venous return caused by the blood clot. It is important for the nurse to recognize this sign because if left untreated, DVT can lead to serious complications such as pulmonary embolism. Therefore, the nurse should further assess the client and notify the healthcare provider for appropriate management.

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: C

Rationale: Evaluating client abilities to perform skills with return demonstrations is a good way for a nurse to prepare the environment for teaching. By observing the clients' abilities to perform the necessary skills, the nurse can tailor the teaching to meet the specific needs of each individual. Return demonstrations allow for immediate feedback and correction if needed, ensuring that the clients understand and can perform the skills accurately. This interactive approach to teaching promotes active learning and enhances retention of information.

Correct Answer: B

Rationale: B. Recommendations for perineal cleansing: Proper perineal hygiene is important in preventing urinary tract infections (UTIs). Teaching the patient to cleanse the perineal area properly can help reduce the risk of UTIs.

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.
