Nursing Interventions and Supportive Care

- Nursing interventions for ARF depend on the cause, stage, and severity of the condition, as well as the patient's individual needs and preferences.

-  Some of the general nursing interventions for ARF include:

  • Monitoring and managing fluid and electrolyte balance: The nurse should assess the patient's fluid status by measuring intake and output, daily weight, vital signs, central venous pressure (CVP), and urine specific gravity. The nurse should also monitor the patient's serum electrolyte levels, especially potassium, sodium, calcium, magnesium, and phosphorus, and report any abnormalities to the physician. The nurse should administer intravenous fluids or blood products as ordered, and adjust the rate and type of fluid according to the patient's response. The nurse should also restrict fluid intake if indicated, and educate the patient on signs of fluid overload or dehydration.
  • Optimizing nutrition: The nurse should consult with a dietitian to provide a suitable diet for the patient with ARF. The diet should be low in protein, sodium, potassium, phosphorus, and fluids, but high in calories, vitamins, and minerals. The nurse should also monitor the patient's nutritional status by checking serum albumin, prealbumin, transferrin, and nitrogen balance. The nurse should encourage oral intake if possible, or administer enteral or parenteral nutrition as ordered. The nurse should also supplement the patient with vitamins and minerals as needed.
  • Ensuring medication safety: The nurse should be aware of the potential nephrotoxic effects of some medications, such as aminoglycosides, nonsteroidal anti-inflammatory drugs (NSAIDs), contrast agents, angiotensin-converting enzyme (ACE) inhibitors, and angiotensin receptor blockers (ARBs). The nurse should avoid or minimize the use of these medications in patients with ARF, or adjust the dosage and frequency according to the patient's renal function. The nurse should also monitor the patient's serum drug levels and report any signs of toxicity to the physician. The nurse should also administer medications that can help improve renal function or prevent complications, such as diuretics, vasodilators, antihypertensives, bicarbonates, calcium gluconate, insulin, albuterol, kayexalate, or dialysis solutions.

Questions on Nursing Interventions and Supportive Care

Correct Answer is A

Explanation

Incorrect. While a renal ultrasound can visualize the blood vessels in the kidneys, its primary purpose is to assess kidney structure, not blood flow.

Correct Answer is C

Explanation

Incorrect. Increasing the client'sfluid intake is not appropriate during a hypotensive episode, as it may not rapidly improve blood pressure and could lead to fluid overload.

Correct Answer is C

Explanation

Incorrect. While the statement is partially true, it does not capture the acute and sudden nature of acute renal failure. The inability of the kidneys to filter waste products from the blood is one of the manifestations of AKI.

Correct Answer is C

Explanation

Incorrect. While UTIs and kidney stones can cause kidney injury, they are not the exclusive causes of acute renal failure, which can have various underlying etiologies.

Correct Answer is C

Explanation

Incorrect. Gentle stretching exercises may not be appropriate for a client experiencing muscle cramps, as stretching could exacerbate the discomfort.

Correct Answer is C

Explanation

Incorrect. Excessive thirst and dry mucous membranes are not specific to hyperkalemia and are not the most critical indicators of severe hyperkalemia.

Correct Answer is B

Explanation

Incorrect. The description provided refers to the insertion of a urinary catheter for bladder drainage, not hemodialysis.

Correct Answer is B

Explanation

Incorrect. Removing jewelry and metallic objects is a standard precaution for all imaging procedures, but it is not specific to a CT scan with contrast dye.

Correct Answer is D

Explanation

Correct. A renal nuclear scan, also known as a renal scintigraphy, involves injecting a small amount of radioactive material intravenously. The radioactive material is taken up by the kidneys, and the scan creates images that assess kidney function and blood flow.QUESTIONS

Correct Answer is A

Explanation

Incorrect. Antihypertensive agents are prescribed to manage hypertension and do not treat anemia in clients with renal failure.QUESTIONS

Correct Answer is A

Explanation

Incorrect. Promoting shallow breathing to retain carbon dioxide is not a recommended intervention for correcting metabolic acidosis. Respiratory acidosis and metabolic acidosis are different types of acid-base imbalances with distinct causes and treatments.

Correct Answer is B

Explanation

Incorrect. Increasing the dwell time would not address the issue of cloudy dialysis fluid and potential infection.

Correct Answer is C

Explanation

Incorrect. Excessive fluid intake and fluid overload may contribute to fluid retention and edema in prerenal acute renal failure, but they are not the primary pathophysiological process in acute renal failure.

Correct Answer is B

Explanation

Incorrect. Increased respiratory rate and shallow breathing are not typical respiratory manifestations of acute renal failure.QUESTIONS

Correct Answer is A

Explanation

Incorrect. Seasonal allergies are not associated with an increased risk of acute renal failure.

Correct Answer is C

Explanation

Incorrect. Chronic kidney disease (CKD. is a risk factor for intrinsic acute renal failure, not postrenal.

Correct Answer is C

Explanation

Incorrect. Decreased respiratory rate and shallow breathing are not directly associated with uremia.

Correct Answer is D

Explanation

Correct. The nurse's best response is to encourage the client to follow their healthcare provider's instructions and avoid medications that may harm the kidneys. Compliance with prescribed treatment plans and avoiding nephrotoxic medications are essential to support kidney function and prevent further damage.

Correct Answer is B

Explanation

Incorrect. Preventing infection and complications is important, but it is not the priority over assessing kidney function in acute renal failure.QUESTIONS

Correct Answer is B

Explanation

Incorrect. Deep breathing exercises are not specific interventions for correcting metabolic acidosis.

Correct Answer is B

Explanation

Incorrect. Increased respiratory rate and depth are not typically associated with acute renal failure or its fluid and electrolyte imbalances.

Correct Answer is A

Explanation

Incorrect. The timing of loop diuretic administration is determined by the healthcare provider's order and the client's specific needs. Taking diuretics at bedtime may result in increased nighttime urination and sleep disruption.QUESTIONS

Incorrect. Diabetes mellitus is a risk factor for chronic kidney disease, but it is not a specific risk factor for prerenal acute renal failure.

Incorrect. While a renal biopsy can provide information about the kidney's structure, its primary purpose is to obtain a tissue sample for histological examination, not to assess blood flow.

Incorrect. Warm, flushed skin and headache are not directly related to metabolic acidosis.

Incorrect. High blood sugar levels and frequent urination are not directly related to acute renal failure. These symptoms are more characteristic of diabetes mellitus.

Incorrect. Fluid restriction is not typically recommended in acute renal failure, especially if the client is experiencing fluid depletion and dehydration.

Incorrect. Chicken and fish are sources of protein and do not have high potassium content that would require restriction in most cases.

Correct. Before an MRI scan, clients need to remove all metal objects and devices, including jewelry, piercings, hearing aids, and certain medical implants. Metal can interfere with the MRI's magnetic field and cause safety concerns during the procedure.

Incorrect. Renal ultrasound is an imaging test that provides information about the structure of the kidneys but does not directly measure GFR.

Incorrect. Administering pain medication before passive range-of-motion exercises is not a standard practice and does not directly prevent complications of immobility.

Incorrect. Elevated creatinine levels can be seen in both acute and chronic kidney diseases, but they are not exclusively seen in chronic kidney disease.

Incorrect. The cost of CRRT and intermittent hemodialysis can vary based on the healthcare setting and the client's needs. The cost-effectiveness depends on individual factors and resource availability.

Incorrect. While anemia can be associated with chronic kidney disease, it is not a specific risk factor for acute renal failure.

Incorrect. Excessive fluid intake may contribute to fluid overload and decreased urine output in prerenal acute renal failure, but it is not the primary pathophysiological process that leads to decreased urine output.

Correct. Fresh fruits and vegetables are generally low in phosphate and are suitable for a low-phosphate diet. These foods can help meet the client's nutritional needs while adhering to the dietary restriction.

Incorrect. Adhesive tape can cause skin irritation and damage when removed, especially in clients at risk for impaired skin integrity.

Incorrect. Thiazide diuretics may cause electrolyte imbalances and metabolic disturbances, but they are not a common cause of prerenal acute renal failure.QUESTIONS

Incorrect. Urinary tract obstruction is also associated with postrenal acute renal failure, not intrinsic causes.

Incorrect. Hypoactive bowel sounds and constipation are not directly related to fluid overload in acute renal failure.

Incorrect. Encouraging the client to drink water freely would exacerbate fluid overload and impair the body's ability to eliminate excess fluids.

Correct. Loop diuretics are prescribed in acute renal failure to increase urine output and promote fluid excretion. This helps reduce fluid overload and decrease edema.

Incorrect. While ciprofloxacin and other antibiotics may have renal-related side effects, they are not a common cause of intrinsic acute renal failure.
