Nursing Elites

1. A client with type 1 diabetes mellitus presents with nausea, vomiting, and abdominal pain. The nurse suspects diabetic ketoacidosis (DKA). Which of the following lab findings would confirm this diagnosis?

• A. Serum glucose of 180 mg/dL
• B. Serum bicarbonate of 22 mEq/L
• C. Blood pH of 7.25
• D. Urine specific gravity of 1.020

Correct answer: C

Rationale: A blood pH of 7.25 is a critical finding in diabetic ketoacidosis (DKA) as it indicates metabolic acidosis, which is a hallmark of this condition. In DKA, there is an accumulation of ketones in the blood, leading to increased acidity. The serum glucose level is typically elevated in DKA, often exceeding 250 mg/dL. A serum bicarbonate level less than 18 mEq/L is usually seen in DKA due to the metabolic acidosis. Urine specific gravity is not a specific indicator for DKA and may vary depending on the individual's hydration status. Therefore, the correct lab finding that confirms DKA in this scenario is a blood pH of 7.25.

2. The client has been vomiting and has had numerous episodes of diarrhea. Which laboratory test should the nurse monitor?

• A. Serum calcium.
• B. Serum phosphorus.
• C. Serum potassium.
• D. Serum sodium.

Correct answer: C

Rationale: During episodes of vomiting and diarrhea, there is a risk of significant potassium loss, leading to potential electrolyte imbalances. Monitoring serum potassium levels is crucial in this situation to assess and manage any abnormalities promptly. Serum calcium (Choice A) is not typically affected by vomiting and diarrhea. Serum phosphorus (Choice B) levels are not commonly altered by these symptoms. Serum sodium (Choice D) may be affected in severe cases of dehydration, but potassium monitoring is a higher priority due to its potential for rapid depletion in vomiting and diarrhea.

3. Which of the following is a priority nursing diagnosis for a client with Addison's disease?

• A. Fluid volume deficit
• B. Risk for infection
• C. Imbalanced nutrition: Less than body requirements
• D. Disturbed body image

Correct answer: A

Rationale: The priority nursing diagnosis for a client with Addison's disease is 'Fluid volume deficit.' Addison's disease is characterized by adrenal insufficiency, resulting in decreased aldosterone production. Aldosterone plays a key role in sodium and water retention in the body. With its deficiency, there is an increased risk of dehydration and electrolyte imbalance, leading to fluid volume deficit. While infection risk, nutrition issues, and body image disturbances are also important considerations for holistic care, addressing the fluid volume deficit takes precedence due to the immediate physiological impact on the client's health and well-being.

4. A client with diabetes insipidus is receiving desmopressin therapy. The nurse should monitor for which of the following potential side effects?

• A. Hyponatremia
• B. Hypernatremia
• C. Hypokalemia
• D. Hypercalcemia

Correct answer: A

Rationale: The correct answer is A: Hyponatremia. Desmopressin, a medication used to treat diabetes insipidus, can cause the retention of water without sodium, leading to dilutional hyponatremia. This occurs because desmopressin increases water reabsorption in the kidneys without affecting sodium levels. Hypernatremia (choice B) is unlikely because desmopressin does not cause excessive sodium retention. Hypokalemia (choice C) and hypercalcemia (choice D) are not typically associated with desmopressin therapy for diabetes insipidus.

5. A client with hypothyroidism is receiving levothyroxine therapy. The healthcare provider should monitor for which of the following signs of medication overdose?

• A. Bradycardia
• B. Weight gain
• C. Tachycardia
• D. Cold intolerance

Correct answer: C

Rationale: The correct answer is C: Tachycardia. Tachycardia is a sign of levothyroxine overdose, indicating that the dose may need to be adjusted. Bradycardia (Choice A) is a sign of hypothyroidism, not an overdose of levothyroxine. Weight gain (Choice B) and cold intolerance (Choice D) are also symptoms of hypothyroidism, not medication overdose.
