1. Which lab value is critical for a patient on heparin therapy?

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

Correct answer: A

Rationale: The correct answer is to monitor aPTT. Activated Partial Thromboplastin Time (aPTT) is crucial for patients on heparin therapy as it helps determine the clotting ability of the blood. By monitoring aPTT, healthcare providers can adjust the dosage of heparin to maintain therapeutic levels and prevent bleeding complications. Monitoring INR is more commonly associated with warfarin therapy, not heparin. Monitoring platelet count is important for assessing the risk of bleeding or clotting disorders but is not specific to heparin therapy. Monitoring sodium levels is not directly related to assessing the effectiveness or safety of heparin therapy.

2. A client with heart failure is receiving digoxin. Which of the following findings should the nurse report to the provider?

A. Heart rate of 78/min.
B. Vision changes.
C. Respiratory rate of 16/min.
D. Blood pressure of 120/80 mm Hg.

Correct answer: B

Rationale: The correct answer is B: Vision changes. Vision changes are a classic sign of digoxin toxicity and should be reported immediately to the provider for further evaluation and management. A heart rate of 78/min, a respiratory rate of 16/min, and a blood pressure of 120/80 mm Hg are within normal ranges and are not typically associated with digoxin toxicity. Therefore, they would not be the priority findings to report in this situation.

3. A group of newly licensed nurses is being taught about client advocacy by a nurse. Which of the following statements by a newly licensed nurse indicates an understanding of the teaching?

A. I will intervene if there is a conflict between a client and their provider.
B. I should not advocate for a client unless they are able to ask me themselves.
C. I will inform a client that their family should help make their health care decisions.
D. I believe the best health care decision is for the provider to decide.

Correct answer: B

Rationale: The correct answer is B because advocating for a client should not be dependent on the client's ability to ask for it personally. Advocacy is crucial to ensure clients' rights are upheld, especially when they are unable to express their wishes. Choice A is incorrect as intervening in a conflict may not always be advocating for the client's best interests. Choice C is incorrect because the family should not make health care decisions for the client without their input. Choice D is incorrect as it disregards the importance of client autonomy and involvement in decision-making.

4. What is the priority intervention for a patient with fluid overload?

A. Administer diuretics
B. Administer IV fluids
C. Provide oral fluids
D. Provide chest physiotherapy

Correct answer: A

Rationale: The correct answer is to administer diuretics. Diuretics help reduce excess fluid in cases of fluid overload, making it the priority intervention. Administering additional IV fluids (choice B) would exacerbate the problem by adding more fluid. Providing oral fluids (choice C) is not the priority as the excess fluid needs to be removed first. Chest physiotherapy (choice D) is not the primary intervention for fluid overload.

5. A nurse is providing discharge teaching to a client who is recovering from a myocardial infarction. Which of the following client statements indicates a need for further teaching?

A. I will take a daily aspirin to prevent another heart attack.
B. I should expect to experience chest pain when I exercise.
C. I will increase my intake of saturated fats.
D. I will participate in a cardiac rehabilitation program.

Correct answer: C

Rationale: The correct answer is C. Increasing the intake of saturated fats can raise cholesterol levels, which is not recommended after a myocardial infarction. Choices A, B, and D are all appropriate statements indicating a good understanding of post-myocardial infarction care. Taking a daily aspirin can help prevent another heart attack, experiencing chest pain with exercise is a common expectation post-myocardial infarction, and participating in a cardiac rehabilitation program is important for recovery and improving heart health.
