1. Which lab value should be monitored in a patient on digoxin?

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

Correct answer: C

Rationale: The correct answer is to monitor digoxin levels in a patient on digoxin. Digoxin is a medication commonly used to treat heart conditions, and monitoring its levels in the blood is crucial to ensure that the patient is within the therapeutic range and to prevent toxicity. Monitoring potassium levels (Choice A) is important due to the potential of digoxin-induced hypokalemia, but the primary focus should be on monitoring digoxin levels. Monitoring calcium levels (Choice B) and sodium levels (Choice D) are not directly related to digoxin therapy and are not the primary lab values of concern when administering digoxin.

2. A nurse is reviewing the laboratory results of a client who has hypocalcemia. Which of the following findings should the nurse expect?

• A. Positive Trousseau's sign
• B. Increased deep tendon reflexes
• C. Hyperactive bowel sounds
• D. Weak, thready pulse

Correct answer: A

Rationale: A positive Trousseau's sign is a key finding in clients with hypocalcemia, indicating neuromuscular irritability. The other choices are not typically associated with hypocalcemia. Increased deep tendon reflexes are more indicative of hypercalcemia. Hyperactive bowel sounds can be seen in hyperactive bowel conditions or diarrhea, not specifically related to hypocalcemia. A weak, thready pulse may indicate cardiovascular issues, such as dehydration, but it is not a typical finding in hypocalcemia.

3. A nurse is caring for a client who is postoperative following a thyroidectomy. The nurse should identify that which of the following client reports is an indication of hypocalcemia?

• A. Constipation
• B. Frequent urination
• C. Numbness and tingling of the fingers
• D. Increased thirst

Correct answer: C

Rationale: The correct answer is C: 'Numbness and tingling of the fingers.' Post-thyroidectomy, hypocalcemia is a concern due to potential damage to the parathyroid glands that regulate calcium levels. Numbness and tingling of the fingers are classic signs of hypocalcemia. Constipation (Choice A) is not typically associated with hypocalcemia. Frequent urination (Choice B) is more indicative of conditions like diabetes or a urinary tract infection. Increased thirst (Choice D) is commonly seen in conditions such as diabetes insipidus or uncontrolled diabetes mellitus, not specifically related to hypocalcemia.

4. A healthcare provider is reviewing laboratory results for a client who is receiving heparin therapy. Which of the following results indicates that the medication is effective?

• A. Platelets 250,000/mm³
• B. aPTT 60 seconds
• C. Hemoglobin 15 g/dL
• D. INR 1.5

Correct answer: B

Rationale: An aPTT of 60 seconds indicates that the client is receiving an effective dose of heparin. The activated partial thromboplastin time (aPTT) measures the time it takes for blood to clot and is used to monitor heparin therapy. A therapeutic range for aPTT during heparin therapy is usually 1.5 to 2 times the control value, which is around 25-35 seconds. Platelets, hemoglobin, and INR values are not direct indicators of the effectiveness of heparin therapy.

5. A client with a nasogastric tube receiving intermittent enteral feedings should be positioned in which way?

• A. Flush the tube with 15 mL of sterile water before feedings.
• B. Place the client in a supine position during feedings.
• C. Position the client with the head of the bed elevated 45 degrees.
• D. Check gastric residuals every 8 hours.

Correct answer: C

Rationale: Positioning the client with the head of the bed elevated at 45 degrees is crucial during enteral feedings to prevent aspiration. This position helps reduce the risk of regurgitation and aspiration of feedings into the lungs. Option A is not necessary before feedings. Placing the client in a supine position (Option B) increases the risk of aspiration. Checking gastric residuals every 8 hours (Option D) is important but not directly related to positioning during enteral feedings.
