Nursing Elites

1. A client with a history of hypertension is prescribed a diuretic. Which of the following laboratory values should the nurse monitor to evaluate the effectiveness of the medication?

• A. Monitor serum calcium levels.
• B. Monitor serum potassium levels.
• C. Monitor serum sodium levels.
• D. Monitor serum magnesium levels.

Correct answer: B

Rationale: The correct answer is to monitor serum potassium levels. When a client is prescribed a diuretic, monitoring serum potassium levels is essential to evaluate the medication's effectiveness and to detect potential electrolyte imbalances. Diuretics can cause potassium loss, leading to hypokalemia, which can have serious consequences such as cardiac arrhythmias. Monitoring serum calcium levels (Choice A) is not typically required when assessing the effectiveness of diuretics. Similarly, monitoring serum sodium levels (Choice C) is important for other conditions but is not the primary concern when evaluating diuretic therapy. Monitoring serum magnesium levels (Choice D) is also important, but potassium levels are more critical in assessing diuretic effectiveness and preventing complications.

2. A healthcare professional is providing care to a client who has a tracheostomy. Which of the following actions should the professional take to prevent complications?

• A. Clean around the stoma with povidone-iodine.
• B. Maintain sterile technique when performing tracheostomy care.
• C. Use clean technique when suctioning the tracheostomy.
• D. Change tracheostomy ties weekly.

Correct answer: B

Rationale: Maintaining sterile technique when performing tracheostomy care is essential in preventing infections and complications. Option A is incorrect because povidone-iodine may be too harsh for cleaning around the stoma and can lead to skin irritation. Option C is incorrect because suctioning a tracheostomy should be done using sterile technique to minimize the risk of introducing pathogens. Option D is incorrect as tracheostomy ties need to be changed more frequently, usually every 1-2 days, to prevent skin breakdown and infection.

3. 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.

4. 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.

5. A client with diabetes mellitus is experiencing polyuria, polydipsia, and polyphagia. What is the most important action for the LPN/LVN to take?

• A. Encourage the client to increase fluid intake.
• B. Monitor the client's blood glucose level.
• C. Administer insulin as prescribed.
• D. Assess the client's urine output.

Correct answer: B

Rationale: The correct answer is to monitor the client's blood glucose level. When a client with diabetes mellitus presents with symptoms of polyuria, polydipsia, and polyphagia, it indicates hyperglycemia. Monitoring blood glucose levels is crucial to assess and manage the client's condition effectively. Option A, encouraging the client to increase fluid intake, may exacerbate polyuria. Option C, administering insulin, should be done based on the healthcare provider's prescription after assessing the blood glucose level. Option D, assessing the client's urine output, is important but not the most immediate action needed in this scenario; monitoring blood glucose levels takes precedence.
