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 A
Explanation
Choice A rationale
For a preschooler, play is the primary mechanism for coping and learning. A pounding board allows the child to express frustration and aggression in a safe, appropriate manner. This type of play helps to relieve tension and anxiety associated with hospitalization. It provides a healthy outlet for emotions that the child may not be able to articulate verbally, which is crucial for this developmental stage.
Choice B rationale
Preschoolers have a limited understanding of complex language. Using medical terminology can be frightening and confusing to them, increasing their anxiety. Nurses should use simple, concrete language that the child can understand, such as "checking your arm" instead of "taking your blood pressure," to help them feel more secure and cooperative with care.
Choice C rationale
Preschoolers thrive on routine and predictability. Establishing a new routine can be disruptive and increase their stress and fear. The nurse should strive to maintain as much of the child's home routine as possible to provide a sense of security and normalcy. This helps them feel more in control and less overwhelmed by the hospital environment.
Choice D rationale
A preschooler may experience separation anxiety when a parent leaves the room. Performing assessments while the parent is present helps the child feel more secure and supported. The parent can also provide comfort and help distract the child, which can make procedures easier and less frightening for the child. This promotes a trusting relationship between the child, parent, and nurse.
Correct Answer is A
Explanation
Choice A rationale
Spironolactone is a potassium-sparing diuretic. Its mechanism of action involves blocking aldosterone receptors in the kidney's distal convoluted tubule and collecting duct, leading to increased sodium and water excretion while retaining potassium. Consequently, taking a potassium supplement concurrently would dangerously increase the risk of hyperkalemia, a condition characterized by high blood potassium levels (normal range is 3.5-5.0 mEq/L), which can cause life-threatening cardiac dysrhythmias.
Choice B rationale
Spironolactone's primary effect is on sodium and potassium balance, not calcium. Calcium supplements do not typically interact with spironolactone in a way that would cause a significant, adverse change in calcium levels. The nurse should instruct the client to avoid supplements that directly alter the electrolytes affected by the medication's mechanism of action.
Choice C rationale
Spironolactone does not significantly impact iron metabolism. Therefore, a client taking an iron supplement would not be at increased risk of an adverse interaction. Iron supplements are generally well-tolerated with spironolactone, and there is no contraindication for their concurrent use. The focus of client teaching should be on electrolytes directly affected by the medication.
Choice D rationale
Spironolactone does not have a direct or clinically significant interaction with magnesium supplements. While diuretics can sometimes affect magnesium levels, spironolactone's primary action is on potassium and sodium. Therefore, there is no major contraindication for the use of magnesium supplements, unlike the life-threatening risk associated with potassium supplementation. *.
