Nursing Elites

1. A nurse is preparing an infusion for a client who was hospitalized with deep-vein thrombosis. The orders read: 25,000 units of heparin in 250 mL of 0.9% sodium chloride to infuse at 800 units/hr. At what rate should the nurse set the infusion pump?

• A. 8 mL/hr
• B. 10 mL/hr
• C. 12 mL/hr
• D. 15 mL/hr

Correct answer: A

Rationale: To calculate the infusion rate, use the formula: (Desired units/hr / Total units) × Volume. In this case, it would be (800 units/hr / 25,000 units) × 250 mL = 8 mL/hr. Therefore, the nurse should set the infusion pump at 8 mL/hr. Choice B, 10 mL/hr, is incorrect because it does not match the calculated rate. Choices C and D, 12 mL/hr and 15 mL/hr respectively, are also incorrect as they do not align with the correct calculation based on the provided data.

2. A healthcare professional is admitting a client who has decreased circulation in his left leg. Which of the following actions should the healthcare professional take first?

• A. Evaluate pedal pulses
• B. Assess skin temperature
• C. Check for capillary refill
• D. Measure the leg circumference

Correct answer: A

Rationale: Evaluating pedal pulses should be the first action taken as it provides immediate information about circulation. This assessment helps in determining the adequacy of blood flow in the client's leg. Assessing skin temperature, checking for capillary refill, and measuring leg circumference are important assessments; however, evaluating pedal pulses is the most crucial initial step in this scenario. Skin temperature assessment and capillary refill check can provide additional valuable information about perfusion, while measuring leg circumference is useful in monitoring for edema. Therefore, for a client with decreased circulation in the left leg, evaluating pedal pulses takes precedence over the other assessments.

3. A young mother of three children complains of increased anxiety during her annual physical exam. What information should the LPN/LVN obtain first?

• A. Sexual activity patterns.
• B. Nutritional history.
• C. Leisure activities.
• D. Financial stressors.

Correct answer: B

Rationale: The LPN/LVN should first obtain the nutritional history in this scenario. Nutrition plays a crucial role in mental health, and deficiencies or imbalances in diet can contribute to anxiety symptoms. Understanding the mother's nutritional intake can help identify any factors exacerbating her anxiety. Sexual activity patterns are not directly relevant to her anxiety symptoms unless specifically indicated. Leisure activities and financial stressors may be important but are secondary to addressing the potential impact of nutrition on anxiety.

4. After repositioning a client who reports shortness of breath, which of the following actions should the nurse take next?

• A. Observe the rate, depth, and character of the client's respirations.
• B. Take the client’s blood pressure.
• C. Assess the client's pulse.
• D. Offer supplemental oxygen.

Correct answer: A

Rationale: Observing the rate, depth, and character of the client's respirations is crucial after repositioning a client experiencing shortness of breath. This action provides immediate information about the client's respiratory status. Checking blood pressure (Choice B) is not the priority in this situation, as assessing respirations is more urgent. Assessing the pulse (Choice C) is also important but does not provide direct information about the client's respiratory status. Offering supplemental oxygen (Choice D) may be necessary based on the assessment of respirations, but it should not be the first action taken without assessing the client's breathing pattern.

5. 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.
