The nurse is admitting a patient who was diagnosed with acute renal failure. Which electrolyte should the nurse expect to be most affected with this disorder?
Phosphorous.
Magnesium.
Potassium.
Calcium.
The Correct Answer is C
Choice A rationale:
While acute renal failure can affect phosphorus levels, potassium is the electrolyte most commonly affected in this condition. Kidneys play a crucial role in regulating potassium levels in the body, and when they fail, potassium levels can become dangerously elevated.
Choice B rationale:
Acute renal failure can lead to alterations in magnesium levels, but potassium is typically more affected. Magnesium imbalances may occur but are not the primary concern in this condition.
Choice C rationale:
As mentioned earlier, potassium imbalances are common in acute renal failure. The nurse should closely monitor the patient's potassium levels and be prepared to intervene if they become too high or too low.
Choice D rationale:
Calcium levels may also be affected in acute renal failure, but potassium remains the most critical electrolyte to monitor in this condition.

Correct Answer is A
Explanation
Choice A rationale:
Fluid volume overload is an excess of fluid in the intravascular and/or interstitial spaces. One of the hallmark signs of fluid volume overload is distended neck veins, which indicates increased venous pressure due to the accumulation of fluid. The neck veins become more visible and prominent, especially when the patient is in a semi-Fowler's position.
Choice B rationale:
Poor skin turgor is a sign of dehydration, not fluid volume overload. It is characterized by the skin's inability to return to its normal position after being gently pinched. In fluid volume overload, the skin may become edematous and puffy, but it does not exhibit poor turgor.
Choice C rationale:
Concentrated hemoglobin and hematocrit levels are seen in conditions of dehydration or hemoconcentration, not in fluid volume overload. In fluid volume overload, there is excess fluid, which may lead to dilutional effects, resulting in decreased concentration of blood components.
Choice D rationale:
Decreased urine output is associated with fluid volume deficit (dehydration) rather than fluid volume overload. In fluid volume overload, there is often an increase in urine output as the body tries to eliminate the excess fluid.
Correct Answer is C
Explanation
Widened QRS Complexes.
Choice A rationale:
Hyperactive deep tendon reflexes are not typical findings in respiratory acidosis. They are more commonly associated with conditions like hypocalcemia or hypercalcemia.
Choice B rationale:
Warm, flushed skin is not directly related to respiratory acidosis. It is not a typical manifestation of this acid-base imbalance.
Choice C rationale:
Widened QRS complexes on an ECG are characteristic findings in respiratory acidosis. Acidosis can lead to changes in the electrical conduction of the heart, resulting in QRS complex widening.
Choice D rationale:
Bounding peripheral pulses are not directly associated with respiratory acidosis. They may be seen in conditions like hyperthyroidism or anemia but are not specific to respiratory acidosis. Remember, always interpret lab results and clinical findings in the context of the patient's overall condition, medical history, and other relevant factors to provide the best care possible.
