Nursing Elites

1. You are the nurse evaluating a newly admitted patients laboratory results, which include several values that are outside of reference ranges. Which of the following would cause the release of antidiuretic hormone (ADH)?

• A. Increased serum sodium
• B. Decreased serum potassium
• C. Decreased hemoglobin
• D. Increased platelets

Correct answer: A

Rationale:

2. While assessing a clients peripheral IV site, the nurse observes a streak of red along the vein path and palpates a 4-cm venous cord. How should the nurse document this finding?

• A. Grade 3 phlebitis at IV site
• B. infection at IV site
• C. Thrombosed area at IV site
• D. infiltration at IV site

Correct answer: A

Rationale:

3. A client with a serum potassium of 7.5 mEq/L and cardiovascular changes needs immediate intervention. Which prescription should the nurse implement first?

• A. Prepare to administer sodium polystyrene sulfate (Kayexalate) 15 g by mouth.
• B. Provide a heart-healthy, low-potassium diet.
• C. Prepare to administer dextrose 20% and 10 units of regular insulin IV push.
• D. Prepare the client for hemodialysis treatment.

Correct answer: C

Rationale: In a client with a serum potassium level of 7.5 mEq/L and cardiovascular changes, the priority intervention is to lower the potassium level quickly to prevent life-threatening complications like arrhythmias. The correct answer is to prepare to administer dextrose 20% and 10 units of regular insulin IV push. This combination helps shift potassium from the extracellular to the intracellular space, reducing serum potassium levels rapidly. Administering sodium polystyrene sulfate (Kayexalate) by mouth may take several hours to work, making it a less effective immediate intervention. Providing a heart-healthy, low-potassium diet is important for long-term management but is not the most urgent action in this situation. While hemodialysis is a definitive treatment for hyperkalemia, it is not the first-line intervention for acute management of high potassium levels with cardiovascular manifestations.

4. The healthcare provider is evaluating a patient's laboratory results. Based on the laboratory findings, what results will cause the release of an antidiuretic hormone (ADH)?

• A. Increased serum sodium
• B. Decreased serum sodium
• C. Decrease in serum osmolality
• D. Decrease in thirst

Correct answer: A

Rationale: The correct answer is A: Increased serum sodium. When serum sodium levels increase, it triggers the release of ADH by the posterior pituitary gland. ADH helps in retaining water, reducing urine output, and maintaining fluid balance. Choices B, C, and D are incorrect because decreased serum sodium, decrease in serum osmolality, and decrease in thirst do not stimulate the release of ADH.

5. A nurse is caring for clients with electrolyte imbalances on a medical-surgical unit. Which clinical manifestations are correctly paired with the contributing electrolyte imbalance? (Select all that do not apply.)

• A. Hypokalemia Flaccid paralysis with respiratory depression
• B. Hyperphosphatemia Paresthesia with sensations of tingling and numbness
• C. . Hyponatremia Decreased level of consciousness
• D.

Correct answer: B
