A patient with chronic renal failure has an occluded arteriovenous fistula, and routine hemodialysis is delayed. However, the patient's serum potassium level is 6.0 mEq/L. What should the nurse expect to be prescribed for this patient? Select all that apply.
Sodium bicarbonate.
Dextrose 10%.
Sodium polystyrene sulfonate (Kayexalate).
Insulin.
Correct Answer : A,C,D
A, C, and D.
Choice A rationale:
The administration of sodium bicarbonate helps to correct acidosis, which can occur in chronic renal failure due to the accumulation of metabolic waste products in the absence of effective kidney function.
Choice C rationale:
Sodium polystyrene sulfonate (Kayexalate) is used to treat hyperkalemia, which is common in chronic renal failure due to impaired potassium excretion by the kidneys.
Choice D rationale:
Insulin can be prescribed to treat hyperkalemia by promoting the uptake of potassium into cells, thereby reducing the serum potassium level. Choice B and E rationale: Dextrose 10% and furosemide (Lasix) are not appropriate treatments for hyperkalemia. Dextrose 10% is a sugar solution and does not impact potassium levels, while furosemide is a loop diuretic that primarily affects sodium and water excretion, not potassium.

Correct Answer is D
Explanation
The correct answer isd. Assess for indications of pulmonary embolism.
Choice A rationale:
Administering a sedative is not appropriate as the priority intervention. Sedatives can depress respiratory function, which is already compromised in this patient.
Choice B rationale:
Preparing for mechanical ventilation might be necessary if the patient’s condition worsens, but it is not the immediate priority. The priority is to identify the underlying cause of the symptoms.
Choice C rationale:
Massaging the calf area for tenderness is not relevant in this context. While calf tenderness can be a sign of deep vein thrombosis (DVT), which can lead to pulmonary embolism, the immediate priority is to assess for pulmonary embolism directly.
Choice D rationale:
Assessing for indications of pulmonary embolism is the priority because the patient’s symptoms (shortness of breath, chest pain, recent use of birth control pills, smoking history, and abnormal ABG values) strongly suggest a pulmonary embolism.Early identification and treatment are crucial to prevent further complications.
Correct Answer is A
Explanation
Choice A rationale:
Hypophosphatemia is a condition characterized by low levels of phosphate in the blood, which can be caused by various factors, including malnutrition. In this case, the patient has a history of stomach ulcers, which might have contributed to poor nutrient absorption. The nurse should request a dietitian consult to ensure the patient receives an appropriate diet rich in phosphorus, which is essential for cellular function, bone health, and energy metabolism.
Choice B rationale:
Providing aluminum hydroxide antacids as prescribed is not the appropriate intervention for hypophosphatemia. Aluminum hydroxide antacids can bind to phosphate in the gastrointestinal tract, reducing its absorption and potentially worsening the patient's already low phosphate levels.
Choice C rationale:
Instructing the patient to avoid poultry, peanuts, and seeds is not suitable for this situation. These foods are good sources of phosphorus, and avoiding them would further deplete the patient's already low phosphate levels.
Choice D rationale:
Instructing the patient to avoid the intake of sodium phosphate is not necessary for hypophosphatemia. While sodium phosphate preparations are used as laxatives, there is no indication that the patient is taking them, and they are not relevant to the management of hypophosphatemia.
