Nursing Elites

1. A nurse is reviewing the laboratory results of a client who has heart failure. Which of the following findings should the nurse report to the provider?

• A. Potassium 4.0 mEq/L
• B. Hemoglobin 12 g/dL
• C. BUN 18 mg/dL
• D. Sodium 137 mEq/L

Correct answer: B

Rationale: The correct answer is B: Hemoglobin 12 g/dL. In a client with heart failure, a decrease in hemoglobin levels can indicate anemia, which can exacerbate heart failure symptoms. Reporting this finding to the provider is crucial for appropriate management. Choice A, Potassium 4.0 mEq/L, is within the normal range (3.5-5.0 mEq/L) and does not typically require immediate reporting. Choice C, BUN 18 mg/dL, and Choice D, Sodium 137 mEq/L, are also within normal ranges and not directly related to heart failure management. Therefore, the hemoglobin level is the most critical finding to report in this scenario.

2. A client with asthma asks how to use a peak flow meter. Which of the following instructions should the nurse provide?

• A. Use the peak flow meter at the same time each day.
• B. Take a slow, deep breath and blow out as hard as you can.
• C. Keep a log of your peak flow readings.
• D. Perform the test before using any bronchodilators.

Correct answer: D

Rationale: The correct answer is to instruct the client to perform the peak flow test before using any bronchodilators. This is important because it provides the most accurate baseline measurement of lung function. Choice A is not necessarily crucial for the accuracy of the test. Choice B describes the technique for spirometry, not peak flow meter use. Choice C, while important for tracking trends, is not directly related to the accuracy of the initial measurement.

3. A nurse is planning care for a client who has a new diagnosis of deep vein thrombosis (DVT). Which of the following interventions should the nurse include?

• A. Massage the affected extremity every 4 hours.
• B. Encourage the client to remain on bed rest.
• C. Apply cold packs to the affected extremity.
• D. Encourage the client to ambulate frequently.

Correct answer: C

Rationale: The correct intervention for a client with deep vein thrombosis (DVT) is to apply cold packs to the affected extremity. Cold packs help reduce swelling and pain by causing vasoconstriction. Massaging the affected extremity could dislodge a clot, leading to serious complications. Encouraging bed rest may increase the risk of clot propagation, while frequent ambulation is contraindicated as it can dislodge clots.

4. A client has a new prescription for nitroglycerin sublingual tablets. Which of the following instructions should the nurse include?

• A. Take a tablet every 5 minutes for pain relief, up to three doses.
• B. Take this medication with a glass of water.
• C. Chew the tablet for faster absorption.
• D. Store the tablets in a refrigerator.

Correct answer: A

Rationale: The correct answer is A: 'Take a tablet every 5 minutes for pain relief, up to three doses.' Nitroglycerin sublingual tablets are used to relieve chest pain or to prevent chest pain before activities known to cause angina. The tablets should be taken every 5 minutes for pain relief, up to three doses, as prescribed. Choice B is incorrect because nitroglycerin sublingual tablets should be placed under the tongue until they dissolve, not taken with water. Choice C is incorrect because nitroglycerin sublingual tablets should not be chewed but placed under the tongue for absorption. Choice D is incorrect because nitroglycerin tablets should be stored in their original container at room temperature away from light and moisture.

5. A healthcare professional is reviewing the results of an ABG performed on a client with chronic emphysema. Which of the following results suggests the need for further treatment?

• A. PaO2 level of 89 mm Hg
• B. PaCO2 level of 55 mm Hg
• C. HCO3 level of 25 mEq/L
• D. pH level of 7.37

Correct answer: B

Rationale: The correct answer is B. A high PaCO2 level (55 mm Hg) in a client with chronic emphysema suggests respiratory acidosis, which requires further treatment. In chronic emphysema, impaired gas exchange leads to elevated carbon dioxide levels in the blood. Option A (PaO2 level of 89 mm Hg) is near the normal range and does not indicate immediate treatment. Option C (HCO3 level of 25 mEq/L) and option D (pH level of 7.37) are within normal limits and do not suggest the need for further treatment in this context.
