Nursing Elites

1. A client with a history of atrial fibrillation is receiving warfarin (Coumadin). Which laboratory value should the LPN/LVN monitor closely while the client is taking this medication?

• A. Blood glucose level
• B. Prothrombin time (PT) and INR
• C. Serum potassium level
• D. Serum creatinine level

Correct answer: B

Rationale: The LPN/LVN should closely monitor Prothrombin time (PT) and INR (Choice B) levels in a client receiving warfarin. These values are crucial to ensure the medication's effectiveness and prevent complications like bleeding. Monitoring blood glucose level (Choice A) is not directly relevant to warfarin therapy. While serum potassium level (Choice C) and serum creatinine level (Choice D) are important for other conditions or medications, they are not specifically required to be monitored when a client is on warfarin.

2. When reviewing EBP about the administration of O2 therapy, what is the recommended maximum flow rate for regulating O2 via nasal cannula?

• A. Regulate O2 via nasal cannula no more than 6L
• B. Regulate O2 via nasal cannula no more than 2L
• C. Regulate O2 via nasal cannula no more than 4L
• D. Regulate O2 via nasal cannula no more than 8L

Correct answer: A

Rationale: The correct answer is to regulate O2 via nasal cannula no more than 6L. This flow rate is generally recommended to ensure adequate oxygen delivery without causing discomfort or potential harm to the patient. Choices B, C, and D are incorrect as they suggest flow rates that are either too low (2L, 4L) or too high (8L). A flow rate of 2L might not provide sufficient oxygen, while 4L could be inadequate for some patients. On the other hand, a flow rate of 8L could be excessive and potentially harmful, leading to complications like oxygen toxicity. Therefore, the optimal recommendation is to regulate O2 via nasal cannula at a maximum of 6L to balance effectiveness and safety.

3. During auscultation of a client experiencing chest pain worsened by inspiration, a nurse hears a high-pitched scratching sound in both systole and diastole with the diaphragm of the stethoscope placed at the left sternal border. Which of the following heart sounds should the nurse document?

• A. Pericardial friction rub
• B. Murmur
• C. S1 and S2
• D. Bruit

Correct answer: A

Rationale: The correct answer is 'Pericardial friction rub.' A pericardial friction rub is a high-pitched, scratching sound heard in both systole and diastole, which is characteristic of pericardial inflammation. This sound is different from a murmur, which is a swooshing or blowing sound due to turbulent blood flow. S1 and S2 are normal heart sounds, and a bruit is a whooshing sound caused by turbulent blood flow in an artery, not related to pericardial inflammation.

4. The nurse is caring for a client with a nasogastric (NG) tube. Which action should the nurse take to maintain patency of the tube?

• A. Flush the tube with 30 ml of water before and after medication administration.
• B. Administer the medication with food to prevent nausea.
• C. Verify tube placement by aspirating stomach contents.
• D. Dilute the medication with normal saline before administration.

Correct answer: A

Rationale: To maintain the patency of a nasogastric (NG) tube, it is essential to flush the tube with 30 ml of water before and after medication administration. This action helps ensure that the tube remains open and free from blockages. Flushing the tube prevents any medication residue from causing blockages, maintaining its patency. Choice B is incorrect because administering medication with food does not relate to maintaining tube patency. Choice C is incorrect as verifying tube placement by aspirating stomach contents is related to confirming correct tube placement, not maintaining patency. Choice D is also incorrect because diluting the medication with normal saline is not primarily aimed at maintaining the tube's patency.

5. A nurse offers pain medication to a client who is postoperative before ambulation. The nurse understands that this aspect of care delivery is an example of which of the following ethical principles?

• A. Fidelity
• B. Autonomy
• C. Justice
• D. Beneficence

Correct answer: D

Rationale: The correct answer is D: Beneficence. Beneficence involves actions intended to benefit the client, such as providing pain relief. In this scenario, the nurse is demonstrating beneficence by offering pain medication to alleviate the client's discomfort and promote their well-being. Fidelity (A) relates to being faithful to agreements and commitments, autonomy (B) refers to respecting a client's right to make decisions about their care, and justice (C) involves fairness and equal treatment. While these ethical principles are important in healthcare, the situation described primarily exemplifies the principle of beneficence.
