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. A client is admitted with a diagnosis of fluid volume deficit. Which clinical finding would the nurse expect?

• A. Bounding pulse
• B. Bradycardia
• C. Oliguria
• D. Dry mucous membranes

Correct answer: D

Rationale: Dry mucous membranes (D) are a common clinical finding indicating fluid volume deficit. In dehydration, there is insufficient fluid in the body, leading to dry mucous membranes due to decreased saliva production. Bounding pulse (A) is associated with fluid volume excess, not deficit. Bradycardia (B) and oliguria (C) are not typical clinical findings of fluid volume deficit but may be seen in fluid volume excess or other conditions.

3. Why is it most important to start intravenous infusions in the upper extremities rather than the lower extremities of adults?

• A. Superficial veins are more easily found in the feet and ankles.
• B. A decreased flow rate could lead to thrombosis formation.
• C. It is more challenging to move a cannulated extremity when using the leg or foot.
• D. Veins in the feet and ankles are located deep, making the procedure more painful.

Correct answer: B

Rationale: The most critical reason for initiating intravenous infusions in the upper extremities of adults is to reduce the risk of thrombosis (B). Venous return is typically better in the upper extremities, decreasing the likelihood of thrombus formation, which could be life-threatening if dislodged. Although superficial veins are easily found in the feet and ankles (A), this is not the primary reason for choosing the upper extremities. Handling a leg or foot with an IV (C) is not significantly more challenging than handling an arm or hand. The depth of veins in the feet and ankles (D) does not primarily determine the site for IV placement.

4. A client is admitted to the hospital with a diagnosis of pneumonia. Which laboratory test result should the nurse monitor to evaluate the client’s respiratory function?

• A. Arterial blood gases (ABGs)
• B. Complete blood count (CBC)
• C. Blood glucose levels
• D. Serum electrolyte levels

Correct answer: A

Rationale: Arterial blood gases (ABGs) are the most appropriate laboratory test to monitor respiratory function in a client with pneumonia. ABGs provide valuable information on oxygenation status, acid-base balance, and how well the lungs are exchanging gases. This information helps in assessing the effectiveness of ventilation and oxygenation, guiding treatment decisions, and evaluating the overall respiratory status of the client.

5. Which intervention is most important to include in the plan of care for a client at high risk for the development of postoperative thrombus formation?

• A. Instruct the client in the use of the incentive spirometer.
• B. Elevate the head of the bed during all meals.
• C. Use aseptic technique when changing the dressing.
• D. Encourage frequent ambulation in the hallway.

Correct answer: D

Rationale: Thrombus formation is a risk for clients who are immobile postoperatively. Encouraging frequent ambulation helps to prevent stasis in the lower extremities, reducing the risk of thrombus formation. This intervention promotes circulation and prevents blood clot formation, making it the most important intervention in this situation.
