1. What ECG change is associated with hyperkalemia?

• A. Flattened T waves
• B. ST depression
• C. Prominent U waves
• D. Elevated ST segments

Correct answer: B

Rationale: The correct ECG change associated with hyperkalemia is ST depression. Hyperkalemia typically presents with ECG changes such as peaked T waves, prolonged PR interval, widened QRS complex, and finally, ST segment depression. Flattened T waves are more commonly associated with hypokalemia. Prominent U waves are seen in hypokalemia as well. Elevated ST segments are not a typical ECG finding in hyperkalemia.

2. What is the first medication to give to a patient experiencing wheezing due to an allergic reaction?

• A. Albuterol via nebulizer
• B. Cromolyn 20 mg via nebulizer
• C. Methylprednisolone 100 mg IV
• D. Aminophylline 500 mg IV

Correct answer: A

Rationale: The correct answer is A, Albuterol via nebulizer. Albuterol is the first-line treatment for wheezing caused by an allergic reaction due to its rapid action in opening airways. Cromolyn (Choice B) is used for prevention rather than acute treatment. Methylprednisolone (Choice C) and Aminophylline (Choice D) are not the first-line treatments for acute wheezing in allergic reactions.

3. A nurse misreads a glucose reading and administers insulin for a blood glucose of 210 instead of 120. What should the nurse monitor the patient for?

• A. Monitor for hyperglycemia
• B. Monitor for signs of hypoglycemia
• C. Administer glucose IV
• D. Document the incident

Correct answer: B

Rationale: The correct answer is B: Monitor for signs of hypoglycemia. The nurse should monitor the patient for hypoglycemia due to the administration of excess insulin. Administering insulin for a blood glucose level of 210 instead of 120 can lead to a rapid drop in blood sugar levels, causing hypoglycemia. Option A is incorrect as hyperglycemia is high blood sugar, which is unlikely in this scenario. Option C is incorrect as administering glucose IV would worsen the hypoglycemia. Option D is not the immediate priority; patient safety and monitoring for adverse effects take precedence.

4. A nurse is caring for a client who has a peripherally inserted central catheter (PICC). For which of the following findings should the nurse notify the provider?

• A. The dressing was changed 7 days ago
• B. The circumference of the client's upper arm has increased by 10%
• C. The catheter has not been used in 8 hours
• D. The catheter has been flushed with 10 mL of sterile saline after medication use

Correct answer: B

Rationale: An increase in the circumference of the client's upper arm by 10% could indicate deep vein thrombosis, which is a serious condition. Deep vein thrombosis can impede blood flow and potentially lead to life-threatening complications. Therefore, the nurse should notify the provider immediately about this finding. Choice A is not an immediate concern as PICC dressing changes are usually done every 7 days. Choice C is a normal finding as catheters may not be used for certain periods. Choice D is a correct procedure for maintaining catheter patency after medication use.

5. A client at high risk for iron deficiency anemia should increase the consumption of which of the following foods?

• A. Yogurt
• B. Apples
• C. Raisins
• D. Cheddar cheese

Correct answer: C

Rationale: The correct answer is C: Raisins. Raisins are a good source of iron, making them beneficial for a client at high risk for iron deficiency anemia. Yogurt (Choice A), apples (Choice B), and cheddar cheese (Choice D) are not significant sources of iron. Other iron-rich foods include dried fruits, red meat, and green leafy vegetables.
