Nursing interventions such as taking daily weights, I&O, and monitoring specific gravity relate to which kidney function?

Regulation of water balance

Regulation of acid-base balance

Regulation of blood pressure

Regulation of metabolic wastes

Answer and Explanation

The Correct Answer is A

Choice A reason: The regulation of water balance by the kidneys involves maintaining the appropriate volume and concentration of body fluids. By taking daily weights, nurses can assess fluid retention or loss, while monitoring intake and output (I&O) helps track fluid balance. Specific gravity measures the concentration of urine, which provides information about the kidneys' ability to concentrate or dilute urine. These interventions directly relate to the kidneys' role in regulating water balance.

Choice B reason: Regulation of acid-base balance by the kidneys involves maintaining the proper pH levels in the blood through excretion or retention of hydrogen ions and bicarbonate. While important, this function is not the primary focus of interventions like daily weights, I&O, and specific gravity monitoring, which are more related to water balance.

Choice C reason: The regulation of blood pressure by the kidneys is achieved through the renin-angiotensin-aldosterone system, which controls blood volume and systemic vascular resistance. Although fluid balance can indirectly affect blood pressure, the specific interventions mentioned are more directly related to water balance than blood pressure regulation.

Choice D reason: Regulation of metabolic wastes involves the kidneys filtering and excreting waste products from the blood. This function is vital for overall health, but interventions like daily weights, I&O, and specific gravity monitoring are more focused on assessing fluid balance rather than directly measuring waste elimination.

Correct Answer is A

Explanation

Choice A reason: Avoiding straining while having a bowel movement is important for patients with a low heart rate. Straining can stimulate the vagus nerve, which can lead to further bradycardia (slowing of the heart rate). By avoiding straining, patients can prevent additional vagal stimulation and help maintain a stable heart rate.

Choice B reason: Limiting the intake of caffeinated drinks to one a day is not directly related to avoiding further slowing of the heart rate. While excessive caffeine can have effects on heart rhythm and overall cardiovascular health, moderate caffeine intake is not typically associated with a significant risk of bradycardia.

Choice C reason: Ensuring that bath water is warm is not directly related to preventing further slowing of the heart rate. While warm water can promote relaxation and comfort, it does not have a direct impact on heart rate management for individuals with bradycardia.

Choice D reason: Modifying strenuous exercise such as running is a good general recommendation for individuals with heart conditions, but it is not specifically targeted at preventing further bradycardia. Exercise modification is more relevant for managing overall cardiovascular health and preventing tachycardia (increased heart rate).

A. "When the antibiotic therapy is complete." B. "As soon as his albumin levels return to normal." C. "Once we complete the fluid resuscitation process." D. "When all of his burn wounds have closed."

Correct Answer is D

Explanation

Choice A reason: Completion of antibiotic therapy does not necessarily correlate with a decrease in the risk of infection in burn patients. While antibiotics can help manage existing infections, the risk for new infections remains until the burn wounds are fully healed. Open burn wounds provide a portal of entry for pathogens, and the presence of necrotic tissue can further increase infection risk.

Choice B reason: Returning albumin levels to normal can improve the overall nutritional status and healing process of a burn patient, but it does not directly reduce the risk of infection. Albumin levels are more indicative of the patient's nutritional status and fluid balance. The primary concern for infection risk remains the open burn wounds, which serve as a direct route for pathogens.

Choice C reason: Completion of the fluid resuscitation process is crucial for stabilizing a burn patient's hemodynamic status and ensuring adequate perfusion to tissues. However, fluid resuscitation does not directly impact the risk of infection. The risk of infection is predominantly related to the presence and extent of open burn wounds.

Choice D reason: The correct response is that the risk for infection significantly decreases when all of the burn wounds have closed. Closed wounds provide a barrier against pathogens and reduce the risk of infection. Wound closure can be achieved through natural healing or surgical interventions such as skin grafting. Until the wounds are fully closed, the patient remains at a high risk for infection.
