A nurse is teaching a client who has osteoarthritis about joint protection strategies.
Which of the following instructions should the nurse include?
Sit in chairs with low, soft backs.
Use both hands to hold objects.
Push up from the bed with your fingers.
Turn doorknobs clockwise.
The Correct Answer is B
Choice A rationale
Sitting in chairs with low, soft backs can worsen osteoarthritis symptoms and increase joint stress. Low chairs require more force from the hips and knees to stand up, which can strain these joints. Soft backs provide inadequate support, leading to poor posture and increased stress on the spine and other joints. Proper joint protection involves maintaining good posture and minimizing strain on affected joints.
Choice B rationale
Using both hands to hold objects distributes the weight and stress evenly across multiple joints, such as those in both wrists and hands, thereby reducing the workload on any single joint. This technique minimizes the risk of joint deformation and pain associated with osteoarthritis by preventing excessive force from being applied to a single joint, a key principle of joint protection.
Choice C rationale
Pushing up from a bed with fingers puts a concentrated, high-impact force on the small joints of the fingers, which are often affected by osteoarthritis. This action can lead to pain, inflammation, and potential deformity over time. Instead, individuals should use their palms or forearms to push up, distributing the force over a larger, stronger surface area.
Choice D rationale
Turning doorknobs clockwise or in any specific direction with a forceful grip can exacerbate joint pain and strain in the fingers and wrist. This motion places significant torque on the affected joints. To protect joints, clients should be advised to use lever-style doorknobs or adaptive devices that require less grip strength and a different motion. *.

Correct Answer is C
Explanation
Choice A rationale
Drowsiness is a symptom of hypothyroidism, not hyperthyroidism (thyrotoxicosis). Levothyroxine is a synthetic thyroid hormone used to treat hypothyroidism. An overdose or excessive dose of this medication would lead to symptoms of hyperthyroidism, which is the opposite of drowsiness. Instead, clients would likely experience increased energy levels, anxiety, or insomnia.
Choice B rationale
Weight gain is a classic symptom of hypothyroidism, not thyrotoxicosis. When the body's metabolism slows down due to insufficient thyroid hormone, the client may gain weight. A client experiencing thyrotoxicosis from an excessive dose of levothyroxine would typically exhibit a hypermetabolic state, which often leads to unintended weight loss despite an increased appetite.
Choice C rationale
A fever is a sign of an accelerated metabolic rate, which is a key feature of thyrotoxicosis. When thyroid hormone levels become excessively high, the body's basal metabolic rate increases significantly, causing an increase in body temperature. This can manifest as a low-grade fever or even a significant fever in severe cases, requiring immediate medical attention.
Choice D rationale
Bradycardia, or a slow heart rate, is a symptom of hypothyroidism. The heart rate slows down as the body's overall metabolic processes decrease. Thyrotoxicosis is characterized by a rapid heart rate, known as tachycardia. This is due to the excessive stimulation of the cardiovascular system by high levels of thyroid hormone. A normal heart rate is typically between 60 and 100 beats per minute. .
Correct Answer is A
Explanation
Choice A rationale
The ST segment represents the time from the end of ventricular depolarization to the beginning of ventricular repolarization. It is identified as the flat baseline following the QRS complex and preceding the T wave. This segment is isoelectric, meaning it's at the same level as the PR segment, and any deviation can indicate myocardial ischemia or injury.
Choice B rationale
The peak of the R wave represents the peak of ventricular depolarization. It signifies the moment of maximum electrical activity in the ventricles, as the impulse spreads through the ventricular walls. It is a critical point in the QRS complex, but it is not the location of the ST segment.
Choice C rationale
The beginning of the P wave marks the onset of atrial depolarization. This electrical event represents the contraction of the atria as they pump blood into the ventricles. The P wave is the first deflection in the cardiac cycle and occurs well before the QRS complex and the ST segment.
Choice D rationale
The interval between the S wave and the T wave is not a standard electrocardiographic term. The correct terminology is the ST segment, which is a segment, not an interval, and it specifically follows the S wave and precedes the T wave. An interval would typically include a wave, like the QT interval. *.
