Nursing Elites

1. A client with a left leg cast is being taught how to use crutches. Which of the following statements should indicate to the nurse that the client understands the teaching?

• A. When descending stairs, I will first shift my weight to my right (unaffected) leg.
• B. I will use crutches to support my weight on my left leg.
• C. When ascending stairs, I will lead with my left leg.
• D. I will keep my crutches under my arms for support.

Correct answer: A

Rationale: The correct answer is A. Shifting weight to the unaffected leg when descending stairs is crucial for maintaining balance and safety. This technique helps prevent falls and distributes weight appropriately. Choices B, C, and D are incorrect because using crutches to support the weight on the injured leg, leading with the injured leg when ascending stairs, and keeping crutches under the arms are all potentially unsafe practices that could lead to further injury or accidents.

2. A client with a diagnosis of myocardial infarction (MI) is being treated. Which laboratory value would be most concerning?

• A. Troponin level of 0.5 ng/mL
• B. Creatine kinase-MB (CK-MB) of 5.0 ng/mL
• C. Serum potassium of 4.5 mEq/L
• D. Blood glucose of 180 mg/dL

Correct answer: A

Rationale: A troponin level of 0.5 ng/mL is elevated, indicating myocardial damage, making it the most concerning finding in a client with a myocardial infarction (MI). Troponin is a highly specific marker for cardiac muscle damage, and elevated levels suggest ongoing injury to the heart muscle. While Creatine kinase-MB (CK-MB) is also a cardiac enzyme, troponin is more specific and sensitive for myocardial damage. Serum potassium and blood glucose levels are important parameters to monitor in MI patients, but in this scenario, the elevated troponin level takes precedence as it directly reflects cardiac injury.

3. 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.

4. Heparin 20,000 units in 500 ml D5W at 50 ml/hour has been infusing for 5.5 hours. How much heparin has the client received?

• A. 11,000 units.
• B. 13,000 units.
• C. 15,000 units.
• D. 17,000 units.

Correct answer: A

Rationale: To calculate the total amount of heparin received, multiply the infusion rate (50 ml/hour) by the total infusion time (5.5 hours). This results in 275 ml of the solution infused. Since there are 20,000 units of heparin in 500 ml, there are 800 units per ml. Therefore, 275 ml contains 220,000 units. However, the heparin is diluted in 500 ml, so the client has received half of this amount, which is 110,000 units. Therefore, the correct answer is 11,000 units. Choices B, C, and D are incorrect as they do not reflect the correct calculation based on the provided information.

5. A healthcare professional is reviewing a client's medication prescription, which reads, 'digoxin 0.25 by mouth every day.' Which of the following components of the prescription should the healthcare professional question?

• A. the medication
• B. the route
• C. the dose
• D. the frequency

Correct answer: C

Rationale: The healthcare professional should question the dose indicated in the prescription. In this case, '0.25' is incomplete without a unit of measurement, such as mg (milligrams). Without a specified unit, the dose lacks the necessary information for accurate administration. Choices A, B, and D are not incorrect components to question in medication prescriptions; however, in this scenario, the incompleteness of the dose is the most critical concern that needs clarification to ensure safe and effective medication administration.
