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 caring for a client with a chest tube. Which observation requires immediate intervention?

• A. Constant bubbling in the suction control chamber
• B. Intermittent bubbling in the water seal chamber
• C. Drainage of 50 ml per hour
• D. Crepitus around the insertion site

Correct answer: D

Rationale: Crepitus around the chest tube insertion site may indicate subcutaneous emphysema, a serious condition that requires immediate attention. It can be a sign of an air leak in the lung or surrounding tissues. Constant bubbling in the suction control chamber is expected in a functioning chest tube system as it indicates proper suction. Intermittent bubbling in the water seal chamber is also normal, showing that the system is functioning correctly, allowing air to escape but not re-enter. Drainage of 50 ml per hour is within the expected range for chest tube output and does not require immediate intervention unless there are other concerning signs such as rapid increase or a sudden change in color or consistency.

3. The client is being taught about the use of syringes and needles for home administration of medications. Which action by the client indicates an understanding of standard precautions?

• A. Remove the needle after discarding used syringes
• B. Wear gloves while disposing of the needle and syringe
• C. Wear a face mask during medication administration
• D. Wash hands before handling the needle and syringe

Correct answer: D

Rationale: The correct answer is D. Washing hands before handling the needle and syringe is a critical step in infection control and adherence to standard precautions. Clean hands help prevent the transfer of microorganisms and reduce the risk of infection. Choices A, B, and C do not directly relate to standard precautions. Removing the needle after discarding used syringes (Choice A) can increase the risk of needlestick injuries. Wearing gloves while disposing of the needle and syringe (Choice B) is important for personal protection but does not specifically address standard precautions. Wearing a face mask during medication administration (Choice C) is not directly related to handling syringes and needles, which are more pertinent to standard precautions.

4. A 3-year-old child is brought to the clinic by his grandmother to be seen for 'scratching his bottom and wetting the bed at night.' Based on these complaints, the nurse would initially assess for which problem?

• A. Allergies
• B. Scabies
• C. Regression
• D. Pinworms

Correct answer: D

Rationale: The correct answer is D, Pinworms. Pinworms are a common cause of itching around the anal area, especially at night, in young children. Scratching the bottom and bedwetting can be indicative of a pinworm infection. Allergies (Choice A) are less likely given the symptoms described. Scabies (Choice B) may cause itching but is less common in causing bedwetting. Regression (Choice C) is not a common cause of these specific symptoms in a 3-year-old child.

5. A client in a provider’s office tells the nurse that, 'I fast for several days each week to help control my weight.' The client takes several medications for various chronic issues. The nurse should explain to the client that which of the following mechanisms that result from fasting puts her at risk for medication toxicity?

• A. Increasing the metabolism of the medications over time
• B. Increasing the protein-binding response
• C. Increasing medications’ transit time through the intestines
• D. Decreasing the excretion of medications

Correct answer: B

Rationale: Fasting can lead to an increased protein-binding response of medications. This can result in a higher concentration of bound medications in the bloodstream, potentially causing toxicity as the medications may not be readily available for metabolism or excretion. Choice A is incorrect because fasting typically doesn't increase medication metabolism. Choice C is incorrect as fasting usually decreases transit time through the intestines. Choice D is incorrect since fasting generally does not decrease medication excretion.
