Nursing Elites

1. 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.

2. When using an open irrigation technique to irrigate a client's indwelling urinary catheter, which of the following actions should the nurse take?

• A. Place the client in a side-lying position
• B. Instill 15 mL of irrigation fluid into the catheter with each flush
• C. Subtract the amount of irrigant used from the client's urine output
• D. Perform the irrigation using a 20 mL syringe

Correct answer: C

Rationale: The correct action for the nurse to take when using an open irrigation technique on a client with an indwelling urinary catheter is to subtract the amount of irrigant used from the client's urine output. This calculation helps ensure an accurate measurement of the client's actual urine output by accounting for the irrigation fluid introduced into the catheter. Placing the client in a side-lying position (Choice A) is not directly related to the irrigation procedure. Instilling a specific volume of irrigation fluid (Choice B) may vary depending on the client's condition and the healthcare provider's order. Using a 20 mL syringe for irrigation (Choice D) is a matter of equipment choice and does not directly impact the calculation of urine output in this context.

3. The client with congestive heart failure (CHF) is receiving furosemide (Lasix). Which laboratory value should the healthcare provider monitor closely?

• A. Potassium
• B. Sodium
• C. Calcium
• D. Magnesium

Correct answer: A

Rationale: Correct! When a client is taking furosemide (Lasix), monitoring potassium levels is crucial due to the potential for hypokalemia. Furosemide is a loop diuretic that can lead to potassium loss through increased urine output. Low potassium levels can predispose the client to cardiac dysrhythmias. Sodium, calcium, and magnesium levels are not typically affected by furosemide to the same extent as potassium, making them less critical to monitor in this scenario.

4. A nurse is planning care for a client who has a prescription for knee-length anti-embolic stockings. Which of the following actions should the nurse take?

• A. Remove the client’s stockings at least once during each shift
• B. Roll the top of the client’s stockings down to just below the knee
• C. Seat the client in a chair for 30 minutes prior to applying stockings
• D. Measure the length of the client’s leg from the heel to the gluteal fold

Correct answer: A

Rationale: The correct action for the nurse to take is to remove the client’s stockings at least once during each shift. This is important to inspect the skin and prevent complications such as pressure injuries or impaired circulation. Rolling the top of the stockings down can compromise their effectiveness in preventing blood clots. Seating the client in a chair prior to applying stockings is not directly related to the care of anti-embolic stockings. Measuring the length of the client’s leg from the heel to the gluteal fold is not necessary for the application or care of knee-length anti-embolic stockings.

5. A healthcare professional working in the emergency department is witnessing the signing of informed consent forms for the treatment of multiple clients during their shift. Which of the following signatures may the healthcare professional legally witness?

• A. A 16-year-old client who is married
• B. A 27-year-old who has schizophrenia
• C. An adoptive parent who brings in their 8-year-old child
• D. A 17-year-old mother who brings in her toddler

Correct answer: A

Rationale: The correct answer is A. A 16-year-old who is married can legally sign an informed consent form. In this case, being married at 16 may indicate legal emancipation or the ability to consent to medical treatment. Choice B is incorrect because having schizophrenia doesn't automatically imply incapacity to provide informed consent. Choice C is incorrect as an adoptive parent does not have the legal authority to provide consent for medical treatment on behalf of a child without proper documentation. Choice D is incorrect as a 17-year-old mother would generally not have the legal capacity to give consent for her toddler, as parental consent is usually required for minors.
