Nursing Elites

1. 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.

2. The nurse is preparing to administer a medication through a nasogastric (NG) tube. Which action should the LPN/LVN take to ensure proper administration?

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

Correct answer: B

Rationale: To ensure proper administration through a nasogastric tube, the LPN/LVN should flush the tube with 30 ml of water before and after medication administration. This action helps ensure the tube is patent, prevents clogging, and helps deliver the medication effectively. Checking the placement of the tube by auscultation (Choice A) is essential but does not directly relate to ensuring proper administration. Administering the medication with food (Choice C) may not always be appropriate for all medications and may not necessarily prevent nausea. Diluting the medication with normal saline (Choice D) is not a standard practice for all medications administered via an NG tube and may alter the medication's effectiveness.

3. A client with limited mobility in his lower extremities is being cared for by a nurse. Which of the following actions should the nurse take to prevent skin breakdown?

• A. Place the client in high-Fowler's position
• B. Increase the client's intake of carbohydrates
• C. Massage the reddened areas with unscented lotion
• D. Have the client use a trapeze bar when changing positions

Correct answer: D

Rationale: The correct answer is to have the client use a trapeze bar when changing positions. This action helps in repositioning without causing friction or shearing, which can lead to skin breakdown. Placing the client in high-Fowler's position (Choice A) may not directly prevent skin breakdown related to limited mobility. Increasing carbohydrate intake (Choice B) is not relevant to preventing skin breakdown. Massaging reddened areas with lotion (Choice C) can potentially cause more harm by increasing friction and damaging the skin further, rather than preventing breakdown.

4. Following major abdominal surgery, a client postoperative refuses to use the incentive spirometer. What is the nurse's priority?

• A. Determine the reason why the client is refusing to use the incentive spirometer.
• B. Insist that the client use the incentive spirometer.
• C. Administer pain medication to help the client use the spirometer.
• D. Document the refusal in the client’s medical record.

Correct answer: A

Rationale: The nurse's priority in this situation is to determine the reason why the client is refusing to use the incentive spirometer. By understanding the client's concerns or barriers, the nurse can address them effectively and encourage the client to use the spirometer for optimal postoperative recovery. Insisting that the client use the spirometer without understanding the underlying reason may lead to further resistance. Administering pain medication as a solution does not address the root cause of refusal and may not be necessary if pain is not the primary reason for refusal. Documenting the refusal is important but should come after understanding the client's perspective to provide appropriate care and follow-up.

5. A client with heart failure is being taught by a nurse on reducing daily sodium intake. What is the most important factor in determining the client's ability to learn new dietary habits?

• A. The involvement of the client in planning the change
• B. The presence of a dietitian during the teaching
• C. The use of dietary supplements
• D. The client's family support

Correct answer: A

Rationale: The most crucial factor in the client's ability to learn new dietary habits is their involvement in planning the change. When clients actively participate in setting their dietary goals, they are more likely to commit to and adhere to the changes. This empowerment fosters a sense of ownership and responsibility, enhancing the chances of successful dietary modifications. The presence of a dietitian, use of dietary supplements, and family support, while beneficial, are not as critical as the client's active participation in planning the dietary changes.
