1. The nurse is caring for a client who is receiving a continuous intravenous infusion of heparin. Which laboratory value should the nurse monitor to evaluate the effectiveness of the therapy?

Correct answer: C

Rationale: The correct answer is C. Partial thromboplastin time (PTT) is the laboratory value that should be monitored to evaluate the effectiveness of heparin therapy. PTT reflects the intrinsic pathway of coagulation and is specifically sensitive to heparin's anticoagulant effects. Monitoring the PTT helps ensure that the client is within the therapeutic range to prevent clot formation without increasing the risk of bleeding. Choices A, B, and D are incorrect because while they are important laboratory values in other contexts, they are not specifically used to monitor the effectiveness of heparin therapy.

2. A client with chronic obstructive pulmonary disease (COPD) is receiving oxygen at 2 liters per minute via nasal cannula. The client reports difficulty breathing. What action should the nurse take first?

Correct answer: C

Rationale: The correct action for the nurse to take first when a client with COPD reports difficulty breathing while receiving oxygen is to check the client's oxygen saturation level. This helps in determining the adequacy of oxygenation and identifying the cause of the breathing difficulty. Increasing the oxygen flow rate (Choice A) may not be appropriate without knowing the current oxygen saturation level. Instructing the client to breathe deeply and cough (Choice B) may not address the immediate need for oxygen assessment. Placing the client in a high-Fowler's position (Choice D) can help with breathing but should come after ensuring proper oxygenation.

3. While assessing a client who is experiencing Cheyne-Stokes respirations, the nurse observes periods of apnea. What action should the nurse implement?

Correct answer: C

Rationale: When a nurse observes periods of apnea in a client experiencing Cheyne-Stokes respirations, measuring the length of the apneic periods is essential. This action helps in determining the severity of Cheyne-Stokes respirations by providing valuable information about the duration of interrupted breathing cycles. Elevating the head of the client's bed (Choice A) may be beneficial in some respiratory conditions but is not the priority in Cheyne-Stokes respirations. Auscultating the client's breath sounds (Choice B) is a general assessment and may not directly address the issue of apnea in Cheyne-Stokes respirations. Suctioning the client's oropharynx (Choice D) is not the initial intervention for managing Cheyne-Stokes respirations unless secretions are obstructing the airway.

4. A nurse is caring for a client with a new colostomy. Which instruction should the nurse include in the client's teaching plan?

Correct answer: B

Rationale: The correct instruction the nurse should include in the client's teaching plan is to empty the ostomy pouch when it is one-third full. This practice helps prevent leakage and skin irritation by maintaining an appropriate pouching system. Changing the ostomy appliance daily (Choice A) is not necessary unless leakage or other issues occur. Rinsing the ostomy pouch with warm water (Choice C) is not a recommended practice as it may cause damage to the pouch. Applying a skin barrier to the peristomal skin (Choice D) is important but not the most crucial instruction in this scenario.

5. The mother of a 6-year-old anemic boy is taught by the nurse to give iron supplements. Which statement indicates that the mother understands the proper administration of iron?

Correct answer: A

Rationale: The correct answer is A because iron supplements are best absorbed on an empty stomach, which maximizes their effectiveness. Giving iron tablets with milk or calcium-rich foods, as mentioned in choice B, should be avoided as they can decrease iron absorption. Choice C is incorrect because iron preparations should not be taken with antibiotics due to potential interactions. Choice D is also incorrect as iron tablets do not cause an increased risk of sunburn, so sunscreen is not necessary specifically due to iron supplementation.
