Nursing Elites

1. When culturing a wound, the nurse should obtain the sample from which part of the wound?

• A. The outer edges of the wound.
• B. All necrotic sections of the wound.
• C. Areas containing purulent or pooled exudates.
• D. Any particularly painful area of the wound.

Correct answer: C

Rationale: To collect a wound culture, the nurse should first clean the wound to remove skin flora and then insert a sterile swab from a culturette tube into the wound secretions.

2. When taking a client's blood pressure, the healthcare professional is unable to distinguish the point at which the first sound was heard. What is the best action for the healthcare professional to take?

• A. Deflate the cuff completely and immediately reattempt the reading.
• B. Reinflate the cuff completely and leave it inflated for 90 to 110 seconds before taking the second reading.
• C. Deflate the cuff to zero and wait 30 to 60 seconds before reattempting the reading.
• D. Document the exact level visualized on the sphygmomanometer where the first fluctuation was seen.

Correct answer: C

Rationale: The correct action when unable to distinguish the point of the first sound during blood pressure measurement is to deflate the cuff to zero and wait 30 to 60 seconds before reattempting the reading. This allows blood flow to return to the extremity, ensuring a more accurate reading the second time. It is important to ensure that the cuff is fully deflated and the appropriate wait time is given to obtain an accurate blood pressure measurement.

3. What assessment finding places a client at risk for problems associated with impaired skin integrity?

• A. Scattered macules on the face
• B. Capillary refill of 5 seconds
• C. Smooth nail texture
• D. Presence of skin tenting

Correct answer: B

Rationale: The correct answer is B. A capillary refill time greater than 3 seconds indicates poor perfusion, leading to impaired skin integrity. Delayed capillary refill can compromise blood flow to the skin, increasing the risk of pressure ulcers or wounds due to reduced tissue perfusion. Choices A, C, and D are incorrect because scattered macules on the face, smooth nail texture, and presence of skin tenting are not direct indicators of impaired skin integrity or risk for skin problems.

4. The client has a chest tube. What is the most important action for the nurse to take?

• A. Ensure the chest tube remains unclamped at all times.
• B. Empty the chest tube every 2 hours.
• C. Keep the drainage system below the level of the chest.
• D. Assess for subcutaneous emphysema.

Correct answer: C

Rationale: Keeping the drainage system below the level of the chest (C) is crucial to ensure proper drainage and prevent backflow of air or fluid into the chest cavity. This position helps maintain the integrity of the closed drainage system. Ensuring the chest tube remains unclamped at all times (A) allows for continuous drainage. Emptying the chest tube (B) should be done as needed, not routinely every 2 hours. Assessing for subcutaneous emphysema (D) is important but not the most critical action in this scenario.

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.
