Nursing Elites

1. The client with chronic renal failure is receiving hemodialysis. Which of the following laboratory values should the nurse monitor closely?

• A. Hemoglobin level.
• B. Blood urea nitrogen (BUN) level.
• C. Serum potassium level.
• D. Creatinine level.

Correct answer: C

Rationale: The serum potassium level should be monitored closely in clients undergoing hemodialysis due to the risk of hyperkalemia. Hemodialysis is used to remove waste products and excess electrolytes like potassium from the blood. Monitoring potassium levels is crucial because an imbalance can lead to serious cardiac complications, making it the priority value to monitor in this scenario. Monitoring hemoglobin levels (choice A) is important for anemia assessment in chronic renal failure but is not directly related to hemodialysis. Blood urea nitrogen (BUN) levels (choice B) and creatinine levels (choice D) are commonly monitored in renal function tests but are not the top priority for monitoring in a client undergoing hemodialysis.

2. The client with deep vein thrombosis (DVT) in the left lower leg is receiving heparin therapy. Which of the following assessments is the most important for the nurse to perform?

• A. Measure the circumference of the left leg.
• B. Assess for signs of bleeding, such as bruising or hematuria.
• C. Monitor the client's vital signs.
• D. Monitor the client's respiratory status.

Correct answer: B

Rationale: The most important assessment for a client with DVT on heparin therapy is to monitor for signs of bleeding, such as bruising or hematuria. Heparin is an anticoagulant medication that can increase the risk of bleeding. Assessing for bleeding is crucial to prevent complications like hemorrhage. Measuring the circumference of the leg may be relevant for assessing for edema but is not as critical as monitoring for bleeding. Monitoring vital signs and respiratory status are important aspects of care but are not the priority when the client is on heparin therapy for DVT.

3. The nurse is caring for a patient who is receiving furosemide (Lasix) and an aminoglycoside antibiotic. The nurse will be most concerned if the patient reports which symptom?

• A. Dizziness
• B. Dysuria
• C. Nausea
• D. Tinnitus

Correct answer: D

Rationale: The correct answer is D: Tinnitus. When furosemide and an aminoglycoside antibiotic are used together, there is an increased risk of ototoxicity. Tinnitus, a ringing in the ears, is a common early sign of ototoxicity. Dizziness (choice A) is a common side effect of furosemide but not specifically related to this drug interaction. Dysuria (choice B) is painful urination and is not directly associated with this drug combination. Nausea (choice C) is a common side effect of furosemide but is not specifically indicative of ototoxicity caused by the drug interaction.

4. The provider has ordered Kayexalate and sorbitol to be administered to a patient. The nurse caring for this patient would expect which serum electrolyte values prior to administration of this therapy?

• A. Sodium 125 mEq/L and potassium 2.5 mEq/L
• B. Sodium 150 mEq/L and potassium 3.6 mEq/L
• C. Sodium 135 mEq/L and potassium 6.9 mEq/L
• D. Sodium 148 mEq/L and potassium 5.5 mEq/L

Correct answer: C

Rationale: Severe hyperkalemia, with a potassium level of 6.9 mEq/L, requires aggressive treatment with Kayexalate and sorbitol to increase the body’s excretion of potassium. The normal range for serum potassium is 3.5 to 5.5 mEq/L, so patients with the other potassium levels would not be treated aggressively or would need potassium supplementation. Therefore, option C (Sodium 135 mEq/L and potassium 6.9 mEq/L) is the correct choice as it indicates severe hyperkalemia warranting the administration of Kayexalate and sorbitol. Options A, B, and D have either potassium levels within normal limits, which would not necessitate this aggressive treatment, or potassium levels that are lower than what would typically prompt the need for Kayexalate and sorbitol.

5. What is the most common side effect of diuretics such as furosemide (Lasix)?

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

Correct answer: A

Rationale: The correct answer is 'Hypokalemia.' Diuretics like furosemide increase the excretion of potassium, leading to hypokalemia as a common side effect. Hyperkalemia (choice B) is the opposite condition characterized by high potassium levels, which is not typically associated with furosemide use. Hypernatremia (choice C) is increased sodium levels, while hyponatremia (choice D) is decreased sodium levels, neither of which are the most common side effects of furosemide. Therefore, choice A is the best answer.
