Nursing a Concept Based Approach to Learning Test Bank Free

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.

Correct Answer: B

Rationale: Assessing postural blood pressures is important in determining if the client may be experiencing orthostatic hypotension, which could have contributed to the fall. Orthostatic hypotension is a sudden drop in blood pressure that can occur when a person stands up from a sitting or lying position. Older adults on antihypertensive medications are at increased risk for orthostatic hypotension. By monitoring postural blood pressures, the nurse can identify fluctuations in blood pressure that may put the client at risk for falls and implement appropriate interventions to prevent future falls. Monitoring serum sodium levels and creatinine levels are important for detecting electrolyte imbalances or kidney dysfunction but do not directly address the issue of orthostatic hypotension related to falls. Monitoring blood pressure every 2 hours may not provide valuable information on postural blood pressure changes that are associated with orthostatic hypotension.

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: B

Rationale: A. Opioids are not typically indicated for mild osteoarthritis of the knees. They are usually reserved for more severe cases or when other pain management options have failed due to the potential for addiction and side effects.

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.
