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

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.

2. A nurse is assessing a client who is 1 day postoperative following a bowel resection. Which of the following findings should the nurse report to the provider?

Correct answer: D

Rationale: Abdominal distention and rigidity may indicate a postoperative complication, such as bowel obstruction or peritonitis, and should be reported to the provider. While monitoring urine output, heart rate, and wound drainage are essential postoperative assessments, they are not as concerning as abdominal distention and rigidity, which could signal a more urgent issue requiring immediate attention.

3. A nurse is caring for a client who is at risk for developing pressure ulcers. Which of the following interventions should the nurse implement?

Correct answer: C

Rationale: Elevating the head of the bed reduces pressure on bony prominences, which helps prevent pressure ulcers.

4. A nurse is providing discharge teaching to a client who has a new prescription for albuterol. Which of the following instructions should the nurse include?

Correct answer: C

Rationale: The correct answer is C: 'You should rinse your mouth after using this medication.' When providing discharge teaching for a client prescribed albuterol, the nurse should include the instruction to rinse the mouth after each use. This is important to prevent dry mouth and oral infections. Choice A is incorrect as albuterol is usually taken during the day to manage symptoms, not at bedtime. Choice B is incorrect as palpitations are not a common side effect of albuterol. Choice D is incorrect as there is no specific requirement to avoid eating before taking albuterol.

5. What is the correct method to teach a patient about self-administration of insulin?

Correct answer: D

Rationale: The correct method to teach a patient about self-administration of insulin is to use a 90-degree angle for injection. This angle ensures proper subcutaneous administration of insulin, which is essential for effective absorption. Injecting into the upper arm (Choice A) is not recommended for insulin administration. While rotating injection sites (Choice B) is important to prevent lipodystrophy, the angle of injection is crucial for proper insulin delivery. Using a 45-degree angle (Choice C) is more suitable for intramuscular injections, not for subcutaneous insulin injections.
