Nursing Elites

1. The nurse is caring for a client with syndrome of inappropriate antidiuretic hormone (SIADH). Which of the following clinical findings should the nurse expect?

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

Correct answer: A

Rationale: In SIADH, there is excessive release of antidiuretic hormone (ADH), leading to water retention and dilutional hyponatremia. Hyponatremia is a hallmark finding in SIADH due to the imbalance between water and sodium levels. Hyperkalemia (Choice B) is not typically associated with SIADH. Hypercalcemia (Choice C) involves elevated calcium levels, which are not directly related to SIADH. Hypernatremia (Choice D) is the opposite of what occurs in SIADH, where sodium levels are usually diluted due to water retention.

2. A nurse is assigned to care for a group of clients. On reviewing the clients' medical records, the nurse determines that which client is at risk for deficient fluid volume?

• A. A client with a colostomy
• B. A client with congestive heart failure
• C. A client with decreased kidney function
• D. A client receiving frequent wound irrigations

Correct answer: A

Rationale: The correct answer is A. Clients with a colostomy are at risk for deficient fluid volume due to the loss of fluid through the colostomy. In colostomy, there can be increased fluid loss through the stoma, which may lead to dehydration and electrolyte imbalances. Choices B, C, and D do not directly relate to the risk for deficient fluid volume. Clients with congestive heart failure are more prone to fluid overload rather than deficient volume. Clients with decreased kidney function are at risk for fluid retention, not deficient volume. Clients receiving frequent wound irrigations may be at risk for infection, but this does not directly indicate deficient fluid volume.

3. Which of the following clinical findings would be most concerning in a client with hypothyroidism?

• A. Bradycardia
• B. Dry skin
• C. Constipation
• D. Depression

Correct answer: A

Rationale: Bradycardia in a client with hypothyroidism is the most concerning finding as it may indicate severe hypothyroidism, leading to decreased heart rate. Bradycardia can be a sign of myxedema coma, a life-threatening condition that requires immediate medical attention. Dry skin, constipation, and depression are common symptoms associated with hypothyroidism but are not as acutely concerning as bradycardia.

4. How often should rotation sites for insulin injection be separated from one another?

• A. Every third day.
• B. Every week.
• C. Every 2-3 weeks.
• D. Every 2-4 weeks.

Correct answer: C

Rationale: Insulin injection sites should be rotated every 2-3 weeks to prevent lipodystrophy and ensure proper insulin absorption. Option A ('Every third day') is too frequent and does not allow enough time for the previous site to heal properly. Option B ('Every week') might not provide adequate time for the tissue to recover. Option D ('Every 2-4 weeks') could potentially lead to overuse of a single injection site, increasing the risk of lipodystrophy and inconsistent insulin absorption. Therefore, the recommended interval of every 2-3 weeks is optimal for insulin injection site rotation.

5. 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.
