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. Mr. Landon is scheduled to undergo a tracheostomy. Which nursing action is essential during tracheal suctioning?

• A. Using a water-soluble lubricant.
• B. Administering 100% oxygen before and after suctioning.
• C. Ensuring that the suction catheter is open during insertion.
• D. Assisting the client to assume a semi-Fowler's position during suctioning.

Correct answer: B

Rationale: Administering 100% oxygen before and after suctioning is crucial to prevent hypoxia, which can occur during tracheal suctioning. Hypoxia can lead to serious complications, making the provision of oxygen essential in maintaining adequate oxygenation levels for the patient undergoing tracheal suctioning. Choice A is incorrect because using a water-soluble lubricant is not directly related to the essential nursing action during tracheal suctioning. Choice C is incorrect as ensuring that the suction catheter is open during insertion is a basic requirement and not the essential action for oxygenation. Choice D is incorrect because assisting the client to assume a semi-Fowler's position is beneficial for comfort and airway alignment but is not as crucial as administering oxygen to prevent hypoxia.

3. What action should be implemented to prevent the formation of a sacral ulcer for an immobile client?

• A. Maintain the client in a lateral position using protective wrist and vest restraints.
• B. Position the client prone with a small pillow below the diaphragm.
• C. Raise the head and knee gatch when lying in a supine position.
• D. Transfer the client to a wheelchair close to the nursing station for observation.

Correct answer: B

Rationale: Positioning the client prone with a small pillow below the diaphragm helps maintain proper alignment and provides optimal pressure relief over the sacral area, reducing the risk of developing a pressure ulcer. This position redistributes pressure away from bony prominences, such as the sacrum, which is crucial in preventing ulcer formation in immobile clients. Choice A is incorrect because using restraints can lead to further complications and does not address pressure relief. Choice C is incorrect as raising the head and knee gatch in a supine position does not directly alleviate pressure over the sacrum. Choice D is incorrect as transferring to a wheelchair does not address pressure relief or optimal positioning to prevent sacral ulcers.

4. 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.

5. After surgery, a patient has decreased cardiac output. What is a likely observation by the nurse?

• A. Decreased urine output
• B. Increased urine output
• C. Flushing of the skin
• D. Hyperventilation

Correct answer: A

Rationale: A decrease in cardiac output can lead to decreased blood flow to the kidneys, resulting in decreased urine output. The kidneys rely on adequate blood supply to filter waste and produce urine. Therefore, a decreased urine output is a common observation when cardiac output is reduced. Choices B, C, and D are incorrect. Increased urine output is not typically associated with decreased cardiac output; flushing of the skin is more related to vasodilation, and hyperventilation is not directly linked to decreased cardiac output.
