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.

Answer and Explanation

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 D

Explanation

Potential Condition.

Based on the provided information, it's challenging to make a definitive diagnosis with the given laboratory results and clinical presentation. The client's symptoms, such as severe abdominal pain, vomiting, dyspnea, yellow sclera, dry mucous membranes, tachycardia, and positive Chvostek and Trousseau signs, suggest a complex clinical picture that requires further investigation and assessment. Action to Take 1: Notify the provider. Rationale: The client's condition appears to be critical and requires immediate medical attention. Notifying the provider will initiate a comprehensive evaluation and potential interventions. Action to Take 2: Withhold medication for diarrhea until the underlying cause is determined. Rationale: Diarrhea can be a symptom of various conditions, and administering medication without a clear diagnosis may mask important clinical information. Parameters to Monitor 1: Serum bicarbonate level.

Rationale:

Monitoring serum bicarbonate levels can help identify potential acid-base imbalances and assess the client's metabolic status, especially given the history of end-stage renal disease. Parameters to Monitor 2: Intake and Output. Rationale: Monitoring intake and output is essential to assess fluid balance and kidney function, especially in a client with end- stage renal disease and potential electrolyte imbalances.

A. Urine specific gravity 1.020. B. Potassium 5.2 mEq/L. C. Hct 6296. D. Sodium 165 mEq/L.

Correct Answer is A

Explanation

Urine specific gravity 1.020.

Choice A rationale:

Urine specific gravity is a measure of urine concentration, indicating the ability of the kidneys to concentrate or dilute urine. A specific gravity of 1.020 falls within the normal range (typically 1.010 to 1.030). An appropriate specific gravity indicates that the client's kidneys are responding well to the IV fluids, maintaining adequate urine output and concentration.

Choice B rationale:

Potassium level of 5.2 mEq/L is above the normal range of 3.5 to 5 mEq/L. However, this value does not specifically indicate whether the client is responding effectively to the IV fluids for dehydration.

Choice C rationale:

Hct (Hematocrit) of 6296 is not a valid measurement; it appears to be a typographical error or an incomplete value. Therefore, it cannot be used to assess the client's response to treatment.

Choice D rationale:

Sodium level of 165 mEq/L is elevated beyond the normal range of 136 to 145 mEq/L. However, this value does not provide information about the client's response to IV fluids for dehydration.

A patient prescribed spironolactone is demonstrating ECG changes and complaining of muscle weakness. The nurse realizes this patient is exhibiting signs of which electrolyte imbalance?

A nurse is caring for a client who is receiving an IV infusion of dextrose 10% in water. The nurse should monitor the client for which of the following adverse effects?

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.

The nurse is caring for a patient who is anxious and dizzy following a traumatic experience. The arterial blood gas findings include: pH 7.48, PaO2 110, PaCO2 25, and HCO3 24. Which intervention should the nurse expect to be prescribed to correct this problem?
