Nursing Elites

1. A nurse is caring for a client who has dehydration. Which of the following findings should the nurse expect?

• A. Bradycardia
• B. Hypotension
• C. Dry mucous membranes
• D. Tachypnea

Correct answer: C

Rationale: Correct! Dry mucous membranes are a common finding in clients with dehydration. Dehydration leads to reduced fluid volume in the body, resulting in dryness of mucous membranes, decreased skin turgor, and thirst. Bradycardia (slow heart rate) is not typically associated with dehydration, as the body tries to compensate for decreased fluid volume by increasing heart rate. Hypotension (low blood pressure) is a possible finding in dehydration due to reduced circulating volume. Tachypnea (rapid breathing) is more commonly seen in conditions like respiratory distress or metabolic acidosis, rather than dehydration.

2. Which electrolyte imbalance should be closely monitored in a patient receiving digoxin?

• A. Monitor potassium levels
• B. Monitor sodium levels
• C. Monitor calcium levels
• D. Monitor glucose levels

Correct answer: A

Rationale: Corrected Rationale: Potassium levels should be monitored closely in a patient receiving digoxin to avoid hypokalemia. Digoxin can increase the risk of developing life-threatening arrhythmias in the presence of low potassium levels. Monitoring sodium, calcium, or glucose levels is not specifically necessary for patients on digoxin, making choices B, C, and D incorrect.

3. A nurse is caring for a client who is receiving enteral nutrition through a nasogastric tube. Which of the following actions should the nurse take?

• A. Flush the tube with 30 mL of sterile water before each feeding
• B. Administer the feeding using a large-bore syringe
• C. Keep the head of the bed elevated to 15 degrees
• D. Replace the feeding bag every 24 hours

Correct answer: A

Rationale: The correct action for the nurse to take is to flush the tube with 30 mL of sterile water before each feeding. This helps maintain tube patency and prevents clogs. Choice B is incorrect because enteral feedings should be administered using a gravity drip method or a pump, not through a large-bore syringe. Choice C is incorrect because the head of the bed should be elevated to at least 30 degrees to reduce the risk of aspiration. Choice D is incorrect because the feeding bag should be replaced every 24 hours to prevent bacterial contamination.

4. What is the most critical lab value to monitor for a patient on heparin therapy?

• A. Monitor aPTT levels
• B. Monitor platelet count
• C. Monitor INR levels
• D. Monitor sodium levels

Correct answer: A

Rationale: The correct answer is to monitor aPTT levels. Activated Partial Thromboplastin Time (aPTT) is crucial for assessing the therapeutic effectiveness of heparin, as it reflects the intrinsic pathway of the coagulation cascade. Monitoring aPTT helps ensure that the patient is within the therapeutic range of heparin, minimizing the risk of bleeding complications. Platelet count (choice B) is important to assess for potential heparin-induced thrombocytopenia but is not the primary lab value to monitor during heparin therapy. INR levels (choice C) are monitored in patients on warfarin therapy, not heparin. Sodium levels (choice D) are not directly related to heparin therapy monitoring.

5. A nurse is assessing a client who has a potassium level of 3.0 mEq/L. Which of the following findings should the nurse expect?

• A. Diarrhea
• B. Muscle weakness
• C. Hypertension
• D. Bradycardia

Correct answer: B

Rationale: Muscle weakness is a common finding in clients with hypokalemia, as potassium is essential for proper muscle function. Diarrhea (choice A) is more commonly associated with hyperkalemia rather than hypokalemia. Hypertension (choice C) is not typically a direct result of low potassium levels. Bradycardia (choice D) is more commonly associated with hyperkalemia, not hypokalemia.
