Nursing Elites

1. Heparin 20,000 units in 500 ml D5W at 50 ml/hour has been infusing for 5.5 hours. How much heparin has the client received?

• A. 11,000 units.
• B. 13,000 units.
• C. 15,000 units.
• D. 17,000 units.

Correct answer: A

Rationale: To calculate the total amount of heparin received, multiply the infusion rate (50 ml/hour) by the total infusion time (5.5 hours). This results in 275 ml of the solution infused. Since there are 20,000 units of heparin in 500 ml, there are 800 units per ml. Therefore, 275 ml contains 220,000 units. However, the heparin is diluted in 500 ml, so the client has received half of this amount, which is 110,000 units. Therefore, the correct answer is 11,000 units. Choices B, C, and D are incorrect as they do not reflect the correct calculation based on the provided information.

2. A healthcare professional is reviewing a client’s medications. They include cimetidine and imipramine. Knowing that cimetidine decreases the metabolism of imipramine, the healthcare professional should identify that this combination is likely to result in which of the following effects?

• A. Decreased therapeutic effects of cimetidine
• B. Increased risk of imipramine toxicity
• C. Decreased risk of adverse effects of cimetidine
• D. Increased therapeutic effects of imipramine

Correct answer: B

Rationale: When cimetidine decreases the metabolism of imipramine, it leads to an increased concentration of imipramine in the body, which can result in imipramine toxicity. This increased risk of toxicity is the likely effect of this drug interaction. Choice A is incorrect because cimetidine's effect on imipramine metabolism does not impact the therapeutic effects of cimetidine. Choice C is incorrect because the interaction does not decrease the risk of adverse effects of cimetidine. Choice D is incorrect as the increased concentration of imipramine can lead to toxicity, not increased therapeutic effects.

3. The healthcare provider is caring for a client with a wound infection. Which type of dressing is most appropriate to use to promote healing by secondary intention?

• A. Dry gauze dressing
• B. Wet-to-dry dressing
• C. Transparent film dressing
• D. Hydrocolloid dressing

Correct answer: D

Rationale: Hydrocolloid dressings are ideal for promoting healing by secondary intention in wound infections. These dressings create a moist environment that supports autolytic debridement and facilitates the healing process. Dry gauze dressings (Option A) may lead to adherence, causing trauma upon removal and disrupting the wound bed. Wet-to-dry dressings (Option B) are primarily used for mechanical debridement and can be painful during dressing changes. Transparent film dressings (Option C) are more suitable for superficial wounds with minimal exudate and are not typically used for wound infections requiring healing by secondary intention.

4. While caring for a client who, while sitting in a chair, starts to experience a seizure, what action should the nurse take?

• A. Lower the client to the floor and place a pad under the client's head.
• B. Hold the client's head still to prevent injury.
• C. Restrain the client to prevent movement.
• D. Place the client in a supine position.

Correct answer: A

Rationale: During a seizure, the priority is to lower the client to the floor to prevent injury and ensure their safety. Placing a pad under the client's head helps protect the head from injury. Choice B, holding the client's head still, is incorrect as it can lead to harm; it's essential to allow movement during a seizure to prevent neck injury. Choice C, restraining the client, is dangerous and can cause harm by restricting movement. Choice D, placing the client in a supine position, is also not recommended during a seizure as it does not provide adequate protection for the client.

5. A nurse is caring for a client who has a new prescription for tube feeding. The nurse understands that the provider prescribed tube feeding because the client:

• A. Is unable to swallow foods by mouth
• B. Has a gastrointestinal obstruction
• C. Requires additional caloric intake to support healing
• D. Is at risk for aspiration

Correct answer: A

Rationale: The correct answer is A: 'Is unable to swallow foods by mouth.' Tube feeding is prescribed when a client is unable to safely swallow food by mouth but has a functional gastrointestinal tract. Option B, 'Has a gastrointestinal obstruction,' is incorrect as tube feeding is not typically prescribed for this reason. Option C, 'Requires additional caloric intake to support healing,' is incorrect because tube feeding is specifically for clients who are unable to swallow. Option D, 'Is at risk for aspiration,' is also incorrect as tube feeding would not be the primary intervention for aspiration risk; other strategies to reduce aspiration risk would be implemented instead.
