Nursing Elites

1. A client is receiving chemotherapy for breast cancer. Which laboratory value would be most important for the nurse to monitor?

• A. White blood cell count
• B. Hemoglobin level
• C. Serum creatinine
• D. Blood glucose level

Correct answer: A

Rationale: The correct answer is to monitor the white blood cell count. Chemotherapy can lead to neutropenia, which is a decrease in white blood cells, particularly neutrophils. Neutropenia increases the risk of infections, making it crucial to monitor the white blood cell count during chemotherapy. Monitoring hemoglobin level is important but not as critical as white blood cell count in this scenario. Serum creatinine and blood glucose levels are not directly impacted by chemotherapy for breast cancer, making them less relevant to monitor in this situation.

2. A client with chronic kidney disease is being assessed. Which laboratory value would be most concerning?

• A. Serum creatinine of 3.0 mg/dL
• B. Blood urea nitrogen (BUN) of 45 mg/dL
• C. Serum potassium of 6.5 mEq/L
• D. Hemoglobin of 10 g/dL

Correct answer: C

Rationale: In a client with chronic kidney disease, an elevated serum potassium level (hyperkalemia) is the most concerning finding. Hyperkalemia can lead to life-threatening cardiac dysrhythmias due to its effect on the electrical conduction system of the heart. Monitoring and managing serum potassium levels are crucial in patients with chronic kidney disease to prevent serious complications. While elevated serum creatinine (Choice A) and Blood Urea Nitrogen (BUN) levels (Choice B) indicate impaired kidney function, hyperkalemia poses an immediate risk of cardiac complications. Hemoglobin levels (Choice D) are typically lower in chronic kidney disease due to decreased erythropoietin production, but they do not present an immediate life-threatening risk like hyperkalemia.

3. How should the nurse transcribe the dosage of this medication on the client's medical record?

• A. 0.3 mg
• B. 0.3 mg
• C. 0.30 mg
• D. 3/10 mg

Correct answer: B

Rationale: The correct way to transcribe the dosage of three tenths of a milligram of levothyroxine IV STAT is 0.3 mg. When expressing decimals less than 1, there should be a leading zero before the decimal point. Choice A is incorrect (.3 mg) because it lacks the leading zero. Choice C (0.30 mg) is incorrect as it includes a trailing zero after the decimal point, which is unnecessary. Choice D (3/10 mg) is incorrect as it presents the dosage as a fraction, which is not the standard format for transcribing medication dosages. Therefore, B (0.3 mg) is the most appropriate and accurate way to document this prescription on the client's medical record.

4. A client's infusion of normal saline infiltrated earlier today, and approximately 500 ml of saline infused into the subcutaneous tissue. The client is now complaining of excruciating arm pain and demanding 'stronger pain medications.' What initial action is most important for the LPN/LVN to take?

• A. Ask about any past history of drug abuse or addiction.
• B. Measure the pulse volume and capillary refill distal to the infiltration.
• C. Compress the infiltrated tissue to measure the degree of edema.
• D. Evaluate the extent of ecchymosis over the forearm area.

Correct answer: B

Rationale: The most important initial action for the LPN/LVN to take in this situation is to measure the pulse volume and capillary refill distal to the infiltration. This assessment helps evaluate the severity of the infiltration and the circulation in the affected arm. Asking about past history of drug abuse or addiction (Choice A) is not the priority when addressing acute arm pain and infiltration. Compressing the infiltrated tissue (Choice C) may exacerbate the pain and is not recommended as the first step. Evaluating the extent of ecchymosis (Choice D) is not as critical as assessing the circulation in the affected arm, which is better addressed by measuring pulse volume and capillary refill.

5. A client is receiving discharge teaching about a new prescription for digoxin (Lanoxin). Which statement by the client indicates a need for further teaching?

• A. I should avoid foods high in potassium while taking this medication.
• B. I will check my pulse before taking the medication.
• C. I should avoid taking antacids simultaneously with this medication.
• D. I will take the medication at the same time every day.

Correct answer: A

Rationale: The correct answer is A because clients taking digoxin should avoid foods high in potassium. High potassium levels can potentiate the effects of digoxin, leading to toxicity. Choices B, C, and D are correct statements regarding digoxin administration. Checking the pulse before taking the medication helps monitor for signs of digoxin toxicity. Avoiding taking antacids simultaneously prevents interactions that may reduce digoxin absorption. Taking the medication at the same time every day helps maintain a consistent blood level, ensuring optimal therapeutic effects.
