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. A client is scheduled for a bronchoscopy. After the nurse explains the procedure, which statement by the client indicates a need for further teaching?

• A. I'm glad I don’t have to lie still for this procedure.
• B. I will have a local anesthetic to help with discomfort.
• C. I hope I get some medicine to relax me.
• D. I can't eat or drink for 6 hours before the procedure.

Correct answer: A

Rationale: The correct answer is A because the client's statement indicates a misunderstanding about the need to lie still during the bronchoscopy procedure. The client actually needs to remain still for the procedure to ensure its accuracy and safety. Choices B, C, and D demonstrate an understanding of the procedure by acknowledging the local anesthetic for discomfort, the possibility of receiving medicine for relaxation, and the requirement to fast before the procedure, respectively.

3. When reviewing a client’s fluid and electrolyte status, what should the nurse report to the provider?

• A. Potassium 5.4
• B. Sodium 140
• C. Calcium 8.6
• D. Magnesium 2.0

Correct answer: A

Rationale: The correct answer is A: 'Potassium 5.4'. A potassium level of 5.4 is elevated (normal range is typically 3.5-5.0 mEq/L) and may indicate hyperkalemia, which can have serious cardiac implications. Elevated potassium levels can lead to life-threatening arrhythmias, so immediate reporting and intervention are necessary. Choice B, 'Sodium 140', falls within the normal range (135-145 mEq/L) and does not require immediate reporting. Choice C, 'Calcium 8.6', falls within the normal range (8.5-10.5 mg/dL) and is not an immediate concern. Choice D, 'Magnesium 2.0', is within the normal range (1.5-2.5 mEq/L) and does not need urgent reporting. Therefore, the nurse should prioritize reporting the elevated potassium level as it poses the most immediate risk.

4. A mother of a child with a neural tube defect asks the nurse what she can do to decrease the chances of having another baby with a neural tube defect. What is the best response by the nurse?

• A. Folic acid should be taken before and after conception.
• B. Multivitamin supplements are recommended during pregnancy.
• C. A well-balanced diet promotes normal fetal development.
• D. Increased dietary iron improves the health of mother and fetus.

Correct answer: A

Rationale: The correct answer is A: 'Folic acid should be taken before and after conception.' Folic acid supplementation before and during early pregnancy has been shown to significantly reduce the risk of neural tube defects. Choice B is incorrect because while multivitamin supplements are beneficial during pregnancy, the specific focus for preventing neural tube defects is on folic acid. Choice C is a general statement about a well-balanced diet and does not specifically address neural tube defects. Choice D is incorrect as it focuses on dietary iron, which is important for overall health but not specifically proven to prevent neural tube defects.

5. A community health nurse is preparing a campaign about seasonal influenza. Which of the following plans should the nurse include as a secondary prevention?

• A. Screening groups of older adults in nursing care facilities for early influenza manifestations
• B. Promoting hand hygiene to prevent the spread of influenza
• C. Administering influenza vaccinations
• D. Educating about the importance of healthy lifestyle choices to prevent influenza

Correct answer: A

Rationale: The correct answer is A. Secondary prevention aims to detect and address health issues early. Screening older adults in nursing care facilities for early influenza manifestations is an example of secondary prevention by identifying cases at an early stage. Choice B, promoting hand hygiene, is a form of primary prevention that aims to prevent the occurrence of influenza. Choice C, administering influenza vaccinations, is a form of primary prevention as well, focusing on preventing the disease before it occurs. Choice D, educating about healthy lifestyle choices, is more related to health promotion and primary prevention rather than secondary prevention.
