1. Which lab value should be closely monitored for a patient receiving heparin therapy?

• A. Monitor aPTT
• B. Monitor INR
• C. Monitor potassium levels
• D. Monitor sodium levels

Correct answer: A

Rationale: The correct answer is to monitor aPTT. Activated Partial Thromboplastin Time (aPTT) is crucial to monitor when a patient is receiving heparin therapy. Heparin works by potentiating antithrombin III, leading to the inhibition of thrombin and factor Xa. Monitoring aPTT helps ensure the patient is within the therapeutic range for heparin, reducing the risk of bleeding complications. Monitoring INR (Choice B) is more relevant for patients on warfarin therapy. Monitoring potassium (Choice C) and sodium levels (Choice D) is important but not specific to heparin therapy.

2. What is the most concerning electrolyte imbalance for a patient receiving digoxin?

• A. Hyperkalemia
• B. Hypokalemia
• C. Hyponatremia
• D. Hypercalcemia

Correct answer: B

Rationale: The correct answer is Hypokalemia. Hypokalemia is the most concerning electrolyte imbalance for a patient receiving digoxin because it can increase the risk of digoxin toxicity. Low potassium levels can potentiate the effects of digoxin on the heart, leading to serious cardiac arrhythmias. Hyperkalemia (Choice A) is not typically associated with digoxin use. Hyponatremia (Choice C) and Hypercalcemia (Choice D) are not directly related to digoxin therapy and do not pose the same risk of toxicity.

3. A nurse is observing bonding between the client and her newborn. Which of the following actions by the client requires the nurse to intervene?

• A. Holding the newborn in an en face position
• B. Asking the father to change the newborn's diaper
• C. Requesting the nurse to take the newborn to the nursery so she can rest
• D. Viewing the newborn's actions as uncooperative

Correct answer: D

Rationale: The correct answer is D because viewing the newborn's actions as uncooperative may indicate the client is struggling to bond, requiring intervention. Choices A, B, and C do not raise concerns about the bonding process between the client and the newborn. Holding the newborn in an en face position is a positive interaction. Asking the father to change the newborn's diaper involves family participation in care. Requesting the nurse to take the newborn to the nursery so she can rest is a valid request for maternal self-care.

4. A healthcare professional is preparing to administer digoxin to a client with heart failure. Which of the following laboratory values should the professional report to the provider?

• A. Potassium 4.0 mEq/L
• B. Calcium 9.5 mg/dL
• C. Sodium 140 mEq/L
• D. Magnesium 2.0 mg/dL

Correct answer: C

Rationale: The correct answer is C: Sodium 140 mEq/L. An elevated sodium level can affect the effectiveness of digoxin therapy and may lead to toxicity. Therefore, it is crucial to report this value to the provider. Potassium, calcium, and magnesium levels are important as well, but elevated sodium can have a more direct impact on digoxin therapy in this scenario.

5. Which electrolyte imbalance should be closely monitored in patients on diuretics?

• A. Hypokalemia
• B. Hyponatremia
• C. Hyperkalemia
• D. Hypercalcemia

Correct answer: A

Rationale: The correct answer is A: Hypokalemia. Patients on diuretics are at risk of developing hypokalemia due to increased potassium excretion by the kidneys. Hypokalemia can lead to serious consequences such as cardiac arrhythmias. Hyponatremia (choice B) is an imbalance of sodium levels and is not typically associated with diuretic use. Hyperkalemia (choice C) is the opposite condition where potassium levels are elevated and is less common in patients on diuretics. Hypercalcemia (choice D) is an excess of calcium in the blood and is not directly related to diuretic use. Therefore, monitoring for hypokalemia is crucial in patients taking diuretics.
