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. A client with frequent urinary tract infections (UTIs) asks the nurse about drinking juice daily to prevent future UTIs. Which response is best for the nurse to provide?

• A. Orange juice has vitamin C, which deters bacterial growth.
• B. Apple juice is the most useful in acidifying the urine.
• C. Cranberry juice stops pathogens' adherence to the bladder.
• D. Grapefruit juice increases the absorption of most antibiotics.

Correct answer: C

Rationale: Cranberry juice is known for its ability to prevent urinary tract infections by reducing the adherence of Escherichia coli bacteria to the cells within the bladder. This property helps in maintaining urinary tract health and preventing recurrent UTIs. Choices A, B, and D are incorrect because while vitamin C in orange juice may have some benefits, it is not specifically known for deterring bacterial growth in the urinary tract. Apple juice does not significantly impact urine acidity, and grapefruit juice does not enhance antibiotic absorption, making them less effective choices for preventing UTIs compared to cranberry juice.

3. 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.

4. A client who is in hospice care complains of increasing amounts of pain. The healthcare provider prescribes an analgesic every four hours as needed. Which action should the nurse implement?

• A. Give analgesics on an around-the-clock schedule for pain management.
• B. Administer analgesic medication only when the pain becomes severe.
• C. Provide medication to keep the client comfortable without inducing sedation.
• D. Allow brief medication-free periods to promote comfort during daily activities.

Correct answer: A

Rationale: The most effective pain management strategy in hospice care involves administering analgesics on an around-the-clock schedule (A) to maintain pain control. Waiting until pain is severe before administering medication (B) is not ideal as it may lead to inadequate pain relief. While providing comfort is crucial in hospice care, sedation that prevents the client from interacting and experiencing their remaining time should be minimized. Therefore, keeping the client comfortable without excessive sedation (C) is preferred. Allowing for some periods without medication (D) may be appropriate but should not compromise the client's comfort and pain control.

5. 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.
