When assessing a client with a serum potassium level of 7.5 mEq/L (7.5 mmol/L), which intervention is most important for the nurse to implement?
Assess strength of deep tendon reflexes.
Determine apical pulse rate and rhythm.
Observe color and amount of urine.
Compare muscle strength bilaterally.
The Correct Answer is B
Choice A rationale
Assessing the strength of deep tendon reflexes is important in evaluating neuromuscular function, but it is not the most critical intervention for a client with hyperkalemia. Hyperkalemia primarily affects cardiac function, so monitoring the heart is crucial.
Choice B rationale
Determining the apical pulse rate and rhythm is the most important intervention for a client with a serum potassium level of 7.5 mEq/L. Hyperkalemia can cause life-threatening cardiac arrhythmias, and monitoring the heart rate and rhythm can help detect early signs of these complications.
Choice C rationale
Observing the color and amount of urine can provide information about kidney function and hydration status, but it is not the most critical intervention for hyperkalemia. The primary concern with hyperkalemia is its effect on the heart.
Choice D rationale
Comparing muscle strength bilaterally can help assess neuromuscular function, but it is not the most critical intervention for hyperkalemia. The focus should be on monitoring cardiac function to prevent life-threatening complications.

Correct Answer is C
Explanation
Choice A rationale
Eschar and slough are indicative of necrotic tissue and are not signs of proper healing. Eschar is a dry, dark scab or falling away of dead skin, typically caused by a burn, or by the bite of a mite or other insect. Slough is a layer or mass of dead tissue separated from surrounding living tissue, as in a wound, sore, or inflammation. Both eschar and slough need to be removed for proper wound healing to occur.
Choice B rationale
Erythema and serosanguineous exudate can be present in the early stages of wound healing, but one week post-surgery, these signs may indicate inflammation or infection rather than proper healing. Erythema is redness of the skin caused by increased blood flow to the capillaries, often a sign of infection or irritation. Serosanguineous exudate is a thin, watery fluid that is slightly pink due to the presence of small amounts of blood, which can be normal immediately after surgery but should decrease over time.
Choice C rationale
A well-approximated incision site is a sign of proper healing. This means that the edges of the wound are close together and aligned, which promotes faster and more efficient healing. Proper approximation of the wound edges reduces the risk of infection and promotes the formation of a strong, healthy scar.
Choice D rationale
Beefy red granulation tissue is a sign of healing in open wounds, not in surgical incisions that are closed. Granulation tissue is new connective tissue and microscopic blood vessels that form on the surfaces of a wound during the healing process. It is typically bright red or pink and indicates that the wound is healing from the inside out. However, in a surgical incision that is healing properly, the wound edges should be well approximated, and granulation tissue should not be visible.
Correct Answer is A
Explanation
Choice A rationale
Smoking cessation is the most important lifestyle modification for preventing and managing cardiac disease. Smoking is a major modifiable risk factor that can cause atherosclerosis, hypertension, arrhythmias, thrombosis, and myocardial infarction. Quitting smoking has a more direct effect on improving the function and structure of the blood vessels and heart, significantly reducing the risk of cardiovascular events and mortality.
Choice B rationale
A low-fat diet is a useful lifestyle modification for preventing and managing cardiac disease, but it is not the most important one. While it helps in lowering cholesterol levels and reducing inflammation, smoking cessation has a stronger influence on overall cardiovascular health.
Choice C rationale
Stress reduction is a helpful lifestyle modification for preventing and managing cardiac disease, but it is not the most important one. Although managing stress can improve heart health, smoking cessation has a more immediate and significant impact on reducing cardiovascular risks.
Choice D rationale
Regular exercise is beneficial for preventing and managing cardiac disease, but it is not the most important lifestyle modification. Exercise helps in maintaining a healthy weight, lowering blood pressure, and improving overall cardiovascular health, but smoking cessation has a greater impact on reducing the risk of cardiovascular events.
