Nursing Elites

1. A client with a diagnosis of coronary artery disease is receiving atorvastatin (Lipitor). Which laboratory test should the nurse monitor to evaluate the effectiveness of this medication?

• A. Complete blood count (CBC)
• B. Serum potassium level
• C. Liver function tests (LFTs)
• D. Serum cholesterol level

Correct answer: C

Rationale: To evaluate the effectiveness of atorvastatin (Lipitor), the nurse should monitor liver function tests (LFTs) (C) because this medication can impact liver function. Complete blood count (CBC) (A), serum potassium level (B), and serum cholesterol level (D) are not directly indicative of the medication's effectiveness in managing coronary artery disease.

2. The client with chronic obstructive pulmonary disease (COPD) is being taught pursed-lip breathing by the nurse. What is the purpose of this technique?

• A. To promote oxygenation by removing secretions.
• B. To reduce the amount of air trapped in the lungs.
• C. To increase the amount of carbon dioxide exhaled.
• D. To slow the respiratory rate and improve air exchange.

Correct answer: C

Rationale: Pursed-lip breathing is used to increase the amount of carbon dioxide exhaled (C) in clients with chronic obstructive pulmonary disease (COPD). By doing so, it helps prevent air trapping and enhances gas exchange, ultimately improving respiratory efficiency. While removing secretions (A) and reducing air trapping (B) can be associated benefits to some extent, the primary goal of pursed-lip breathing is to optimize carbon dioxide elimination and enhance breathing mechanics. Slowing the respiratory rate (D) is not the primary purpose of pursed-lip breathing.

3. During a 30-second interval, the nurse counts six respirations, and the client coughs three times. In repeating the count for a second 30-second interval, the nurse counts eight respirations. What respiratory rate should the nurse document?

• A. 14
• B. 16
• C. 17
• D. 28

Correct answer: B

Rationale: The nurse should document a respiratory rate of 16. The second count of eight respirations in a 30-second interval is the most accurate as it was not interrupted by the client coughing. Therefore, this rate reflects the client's typical respiratory pattern and should be documented. Choices A, C, and D are incorrect as they do not consider the interruption caused by the client coughing during the first count, which could have affected the accuracy of the result. The second count of eight respirations provides a more reliable indication of the client's respiratory rate.

4. When assisting a client with right-sided hemiplegia to get into a wheelchair, how should the nurse position the wheelchair?

• A. On the left side of the bed facing the foot of the bed.
• B. On the right side of the bed facing the head of the bed.
• C. Perpendicular to the bed on the right side.
• D. Facing the bed on the left side of the bed.

Correct answer: A

Rationale: Positioning the wheelchair on the left side of the bed facing the foot of the bed is the correct approach when assisting a client with right-sided hemiplegia. Placing the wheelchair on the left side allows the client to stand on their unaffected foot and pivot to sit down safely. This positioning facilitates a smoother transfer and helps maintain the client's stability during the process. Choice B is incorrect because positioning the wheelchair on the right side facing the head of the bed would make it challenging for the client to transfer due to their right-sided hemiplegia. Choice C is incorrect as placing the wheelchair perpendicular to the bed on the right side may not provide the necessary space and angle for a safe transfer. Choice D is incorrect as facing the bed on the left side of the bed does not provide the optimal position for the client to transfer from the bed to the wheelchair effectively.

5. A client is to receive cimetidine (Tagamet) 300 mg q6h IVP. The preparation arrives from the pharmacy diluted in 50 ml of 0.9% NaCl. The nurse plans to administer the IVPB dose over 20 minutes. For how many ml/hr should the infusion pump be set to deliver the secondary infusion?

• A. 75 ml/hr
• B. 150 ml/hr
• C. 225 ml/hr
• D. 300 ml/hr

Correct answer: B

Rationale: To calculate the infusion rate, set up a ratio proportion problem: 50 ml/20 min = x ml/60 min. Cross multiply to solve: 50 × 60 / 20 = 150 ml/hr. Therefore, the infusion pump should be set to deliver the secondary infusion at a rate of 150 ml/hr. Option A, 75 ml/hr, is incorrect because it does not account for the correct calculation. Option C, 225 ml/hr, is incorrect as it is too high a rate based on the calculation. Option D, 300 ml/hr, is also incorrect as it does not align with the correct calculation for the infusion rate.
