1. Which of the following is the best intervention for managing dehydration?

• A. Administer antiemetics to prevent nausea
• B. Monitor fluid and electrolyte levels
• C. Encourage the client to drink more fluids
• D. Administer intravenous fluids

Correct answer: B

Rationale: The best intervention for managing dehydration is to monitor fluid and electrolyte levels. This approach allows healthcare providers to assess the severity of dehydration, determine appropriate fluid replacement therapy, and prevent complications. Administering antiemetics (Choice A) may help with nausea but does not address the underlying issue of dehydration. Encouraging the client to drink more fluids (Choice C) may be appropriate for mild dehydration but can be inadequate for moderate to severe cases. Administering intravenous fluids (Choice D) is crucial for severe dehydration or cases where oral rehydration is ineffective, but monitoring fluid and electrolyte levels should precede this intervention.

2. How should a healthcare professional assess a patient for potential deep vein thrombosis (DVT)?

• A. Assess for unilateral leg swelling
• B. Encourage early mobilization
• C. Check for calf tenderness
• D. Observe for redness and warmth

Correct answer: A

Rationale: To assess a patient for potential deep vein thrombosis (DVT), healthcare professionals should look for unilateral leg swelling. This is a classic sign of DVT. While encouraging early mobilization is generally beneficial for preventing DVT, it is not a method of assessment. Checking for calf tenderness is also relevant but not as specific as unilateral leg swelling. Observing for redness and warmth can be signs of inflammation but are not as specific to DVT as unilateral leg swelling.

3. What are the complications of untreated deep vein thrombosis (DVT)?

• A. Pulmonary embolism and stroke
• B. Kidney failure and hypertension
• C. Liver failure and electrolyte imbalance
• D. Fluid overload and bradycardia

Correct answer: A

Rationale: Corrected Rationale: Untreated DVT can lead to complications such as pulmonary embolism and stroke. Pulmonary embolism occurs when a blood clot from the leg travels to the lungs, potentially blocking blood flow and causing respiratory distress. Stroke can occur if a blood clot dislodges from the leg veins, travels to the brain, and obstructs a blood vessel, leading to brain tissue damage. Both of these complications are life-threatening if not managed promptly. The other choices (B, C, D) do not represent common complications of untreated DVT and are therefore incorrect.

4. A nurse is reviewing the medical record of a client with dementia who frequently becomes agitated. What should the nurse prioritize?

• A. Investigate the client's fluid and electrolyte balance
• B. Investigate the client's recent medication changes
• C. Investigate recent changes in cognitive functioning
• D. Investigate the client's psychosocial environment

Correct answer: B

Rationale: The correct answer is to investigate the client's recent medication changes. In a client with dementia who frequently becomes agitated, medication changes can often be a significant factor contributing to their behavior. Checking recent medication changes can help identify if any specific medication is causing or exacerbating the agitation. Choice A about fluid and electrolyte balance is less likely to be the priority unless there are specific indications in the medical record. Choice C, investigating recent changes in cognitive functioning, may be important but addressing the agitation first is a more immediate concern. Choice D, investigating the client's psychosocial environment, is also important but may not directly address the immediate cause of the agitation as medication changes could.

5. What is the proper technique for obtaining a blood specimen from a central venous line?

• A. Use sterile gloves and discard the first 10 mL of blood
• B. Flush the line with heparin and then draw the specimen
• C. Draw the specimen and then administer heparin
• D. Use non-sterile gloves to reduce contamination risk

Correct answer: A

Rationale: The correct technique for obtaining a blood specimen from a central venous line is to use sterile gloves and discard the first 10 mL of blood. This practice helps ensure that the blood sample collected is not contaminated. Choice B is incorrect because flushing the line with heparin before drawing the specimen can contaminate the sample. Choice C is incorrect as administering heparin before drawing the specimen can affect the accuracy of the blood sample. Choice D is incorrect as using non-sterile gloves increases the risk of contamination, which is not recommended when obtaining a blood specimen from a central venous line.
