Nursing Elites

1. The nurse is caring for a newly admitted patient who has severe gastroenteritis. The patient’s electrolytes reveal a serum sodium level of 140 mEq/L and a serum potassium level of 3.5 mEq/L. The nurse receives an order for intravenous 5% dextrose and normal saline with 20 mEq/L potassium chloride to infuse at 125 mL per hour. Which action is necessary prior to administering this fluid?

• A. Evaluate the patient’s urine output.
• B. Contact the provider to order arterial blood gases.
• C. Request an order for an initial potassium bolus.
• D. Suggest a diet low in sodium and potassium.

Correct answer: A

Rationale: Prior to administering IV fluids containing potassium, it is crucial to evaluate the patient's urine output. If the urine output is less than 25 mL/hr or 600 mL/day, there is a risk of potassium accumulation. Patients with low urine output should not receive IV potassium to prevent potential complications. Contacting the provider for arterial blood gases is unnecessary in this scenario as it does not directly relate to the administration of IV fluids with potassium. Administering potassium as a bolus is not recommended due to potential adverse effects. While dietary considerations are important, suggesting a low-sodium and low-potassium diet is not the immediate action required before administering IV fluids with potassium chloride.

2. The healthcare professional is reviewing a patient’s chart prior to administering gentamicin (Garamycin) and notes that the last serum peak drug level was 9 mcg/mL and the last trough level was 2 mcg/mL. What action will the healthcare professional take?

• A. Administer the next dose as prescribed.
• B. Obtain repeat peak and trough levels before administering the next dose.
• C. Report potential drug toxicity to the patient’s healthcare provider.
• D. Notify the patient’s healthcare provider of decreased drug therapeutic level.

Correct answer: C

Rationale: Gentamicin peak levels should ideally be between 5 to 8 mcg/mL, and trough levels should be within the range of 0.5 to 2 mcg/mL to ensure therapeutic efficacy while minimizing toxicity risk. In this case, the patient's peak level is above the recommended range, and the trough level is at the higher end, indicating potential drug toxicity. Therefore, the correct action for the healthcare professional is to report the possibility of drug toxicity to the patient’s healthcare provider. Administering the next dose as prescribed (Choice A) would exacerbate the toxicity risk. Obtaining repeat peak and trough levels (Choice B) may confirm the current levels but does not address the immediate concern of potential toxicity. Reporting a decreased drug therapeutic level (Choice D) is not the priority in this scenario, as the focus should be on addressing the potential toxicity issue.

3. A woman has been scheduled for a routine mammogram. What should the nurse tell the client?

• A. That mammography takes about 1 hour
• B. Not to eat or drink on the morning of the test
• C. That there is no discomfort associated with the procedure
• D. That deodorants, powders, or creams used in the axillary or breast area must be washed off before the test

Correct answer: D

Rationale: The correct answer is D. The nurse should instruct the client to avoid using deodorants, powders, or creams on the day of the mammogram. These products used in the axillary or breast area can interfere with the mammogram results and must be washed off before the test. Choices A, B, and C are incorrect because mammography typically takes less than 30 minutes, there is no need for fasting before the test, and some discomfort may be experienced during the procedure.

4. A nurse is teaching a nursing student how to measure a carotid pulse. The nurse should tell the student to measure the pulse on only one side of the client’s neck primarily because:

• A. It is unnecessary to use both hands
• B. Feeling dual pulsations may lead to an incorrect measurement
• C. Palpating both carotid pulses simultaneously could occlude the trachea
• D. Palpating both carotid pulses simultaneously could cause the heart rate and blood pressure to drop

Correct answer: D

Rationale: The correct answer is D. Applying pressure to both carotid arteries at the same time is contraindicated. Excess pressure to the baroreceptors in the carotid vessels could cause the heart rate and blood pressure to reflexively drop. Palpating both carotid pulses simultaneously could also interfere with the flow of blood to the brain, possibly causing dizziness and syncope. Choices A, B, and C are incorrect. It is necessary to use both hands to measure the carotid pulse accurately. Feeling dual pulsations does not lead to an incorrect measurement, and palpating both carotid pulses simultaneously does not occlude the trachea.

5. A male client comes into the emergency department with a serum creatinine of 2.2 mg/dL and a blood urea nitrogen (BUN) of 24 mg/dL. What question should the nurse ask first when taking this client’s history?

• A. Have you been taking any aspirin, ibuprofen, or naproxen recently?
• B. Do you have anyone in your family with renal failure?
• C. Have you had a diet that is low in protein recently?
• D. Has a relative had a kidney transplant lately?

Correct answer: A

Rationale: The correct question to ask the client first is about their recent intake of nephrotoxic medications like aspirin, ibuprofen, or naproxen. Elevated serum creatinine and BUN levels indicate possible renal issues, making it crucial to assess potential causes such as medication-induced nephrotoxicity. Inquiring about family history of renal failure or recent kidney transplants would not provide immediate insights into the client's current renal condition. While a diet low in protein could influence BUN levels, it is important to address medication history first due to the acute presentation in the emergency department.
