Nursing Elites

1. A client with a history of chronic kidney disease is scheduled for a CT scan with contrast. Which laboratory value should the nurse review before the procedure?

• A. Serum potassium
• B. Blood urea nitrogen (BUN)
• C. Serum creatinine
• D. Serum glucose

Correct answer: C

Rationale: Before a CT scan with contrast, the nurse should review the serum creatinine level. This is crucial in assessing kidney function because contrast agents can potentially worsen renal function, leading to contrast-induced nephropathy. Monitoring serum creatinine helps in identifying patients at risk and taking necessary precautions. Serum potassium (Choice A) is important in conditions like hyperkalemia but is not the priority before a contrast CT scan. Blood urea nitrogen (BUN) (Choice B) is another renal function test but is not as specific as serum creatinine for assessing kidney function. Serum glucose (Choice D) is important in monitoring blood sugar levels, especially in diabetic patients, but it is not directly related to the risk of contrast-induced nephropathy in this scenario.

2. The nurse is preparing a 50 ml dose of 50% dextrose IV for a client with insulin shock. What is the most immediate intervention by the nurse?

• A. Dilute the dextrose in one liter of 0.9% Normal Saline solution.
• B. Mix the dextrose in a 50 ml piggyback for a total volume of 100 ml.
• C. Push the undiluted dextrose slowly through the current IV infusion.
• D. Ask the pharmacist to add the dextrose to a TPN solution.

Correct answer: C

Rationale: The correct immediate intervention by the nurse in this situation is to push the undiluted 50% dextrose slowly through the current IV infusion. This is because in cases of insulin shock, where the client has dangerously low blood sugar levels, administering 50% dextrose directly into the bloodstream helps rapidly increase blood glucose levels. Choice A is incorrect because diluting the dextrose in one liter of normal saline would delay the administration of glucose, which is needed urgently. Choice B is incorrect as mixing the dextrose in a piggyback solution would also delay the administration of the concentrated dextrose. Choice D is incorrect because adding dextrose to a TPN solution is not the immediate intervention needed to address the low blood sugar levels in a client experiencing insulin shock.

3. A client who received multiple antihypertensive medications experiences syncope due to a drop in blood pressure to 70/40. What is the rationale for the nurse's decision to hold the client's scheduled antihypertensive medication?

• A. Increased urinary clearance of the multiple medications has produced diuresis and lowered the blood pressure
• B. The antagonistic interaction among the various blood pressure medications has reduced their effectiveness
• C. The additive effect of multiple medications has caused the blood pressure to drop too low.
• D. The synergistic effect of the multiple medications has resulted in drug toxicity and resulting hypotension.

Correct answer: C

Rationale: When medications with a similar action are administered, an additive effect occurs that is the sum of the effects of each medication. In this case, several medications that all lower blood pressure, when administered together, resulted in hypotension.

4. A female client receives a prescription for alendronate sodium (Fosamax) to treat her newly diagnosed osteoporosis. What instruction should the nurse include in the client's teaching plan?

• A. Take on an empty stomach with a full glass of water.
• B. Take with food to avoid stomach upset.
• C. Take before bedtime with a light snack.
• D. Take with milk to enhance absorption.

Correct answer: A

Rationale: The correct answer is to take alendronate on an empty stomach with a full glass of water. This instruction is essential to ensure proper absorption and prevent esophageal irritation. Taking alendronate with food, before bedtime with a light snack, or with milk can interfere with its absorption and effectiveness, leading to potential side effects or reduced therapeutic benefits.

5. A male client is having abdominal pain after a left femoral angioplasty and stent, and is asking for additional pain medication for right lower quadrant pain (9/10). Two hours ago, he received hydrocodone/acetaminophen 7.5/325 mg. His vital signs are elevated from previous readings: temperature 97.8°F, heart rate 102 beats/minute, respiration 20 breaths/minute. His abdomen is swollen, the groin access site is tender, peripheral pulses are present, but the left is greater than the right. What data is needed to make this report complete?

• A. Client's lungs are clear bilaterally, and oxygen saturation is 97%.
• B. Surgeon needs to see the client immediately to evaluate the situation.
• C. Left peripheral pulses were present only by Doppler pre-procedure.
• D. Client's history includes multiple back surgeries and chronic pain.

Correct answer: B

Rationale: The correct answer is B. In this scenario, the client is experiencing abdominal pain after a left femoral angioplasty and stent, with signs of potential complications such as a swollen abdomen, tenderness at the groin access site, and unequal peripheral pulses. The client's vital signs are also elevated, indicating a worsening condition. Given these findings, the immediate evaluation by the surgeon is crucial to assess for serious complications like internal bleeding or ischemia. Choice A is incorrect as the focus should be on the urgent need for surgical evaluation rather than lung sounds and oxygen saturation. Choice C is irrelevant to the immediate management of the client's current situation. Choice D, while providing background information, is not essential for the urgent intervention required in this case.
