A nurse in an emergency department is caring for a client who reports substernal chest pain and dyspnea. The client is vomiting and is diaphoretic. Which of the following laboratory tests are used to diagnose a myocardial infarction? (Select all that apply.)
- A. Troponin I, Troponin T, CPK, Myoglobin
- B. Plasma low-density lipoproteins
- C. White blood cell count
- D. Blood glucose level
Correct Answer: A
Rationale: The correct answer is A. Troponin I, Troponin T, CPK, and Myoglobin are all specific laboratory tests used to diagnose a myocardial infarction. Troponin I and T are cardiac biomarkers released into the bloodstream following myocardial cell injury. Creatine phosphokinase (CPK) is an enzyme found in high concentrations in the heart muscle, and elevated levels indicate myocardial damage. Myoglobin is a protein released from damaged muscle cells, including cardiac muscle. These tests provide crucial information to confirm the diagnosis of a myocardial infarction.
Plasma low-density lipoproteins are not specific for diagnosing a myocardial infarction. White blood cell count is not typically used for diagnosing a myocardial infarction, although it may be elevated in response to inflammation associated with heart damage. Blood glucose level is not specific for diagnosing a myocardial infarction and

A rehabilitation nurse is caring for a client who has had a spinal cord injury that resulted in paraplegia. After a week on the unit, the nurse notes that the client is withdrawn and increasingly resistant to rehabilitative efforts by the staff. Which of the following actions should the nurse take?
- A. Encourage the client to discuss their feelings
- B. Establish a plan of care with the client that sets attainable goals
- C. Increase the frequency of physical therapy sessions
- D. Allow the client to set the schedule for rehabilitation
Correct Answer: B
Rationale: The correct answer is B: Establish a plan of care with the client that sets attainable goals. This is because involving the client in setting realistic goals can empower them and increase motivation for rehabilitation. By collaborating with the client, the nurse can address the client's needs and preferences, leading to a more personalized and effective rehabilitation plan. Encouraging the client to actively participate in their care promotes autonomy and fosters a sense of control over their situation.
Other choices are incorrect:
A: Encouraging the client to discuss their feelings is important, but it may not directly address the need for a structured plan of care with attainable goals.
C: Increasing the frequency of physical therapy sessions may be overwhelming for the client and not address the underlying issue of lack of motivation.
D: Allowing the client to set the schedule for rehabilitation may not provide the structure and guidance needed for effective rehabilitation.
A nurse is providing teaching to a client who has had a total abdominal hysterectomy and bilateral salpingo-oophorectomy for uterine cancer. Which of the following instructions should the nurse include in the teaching?
- A. Artificial lubrication can be used to treat vaginal itching and dryness.
- B. Estrogen therapy will reverse vaginal dryness.
- C. Do not use tampons for 6 months.
- D. Avoid sexual activity for 1 year.
Correct Answer: A
Rationale: Correct Answer: A. Artificial lubrication can be used to treat vaginal itching and dryness.
Rationale: After a total abdominal hysterectomy and bilateral salpingo-oophorectomy, the client will experience menopausal symptoms due to the removal of the ovaries. Vaginal dryness and itching are common symptoms that can be managed with artificial lubrication. Estrogen therapy is contraindicated in this client due to the history of uterine cancer. Using tampons can increase the risk of infection post-surgery. Avoiding sexual activity for 1 year is not necessary unless advised by the healthcare provider.
A nurse is teaching a client with a history of calcium oxalate kidney stones. What advice should be given?
- A. Limit fluid intake to 1 L per day.
- B. Drink 3 L of fluid every day.
- C. Increase calcium intake.
- D. Avoid all citrus juices.
Correct Answer: B
Rationale: The correct answer is B: Drink 3 L of fluid every day. Increasing fluid intake helps prevent the formation of kidney stones by diluting the urine and reducing the concentration of minerals like calcium oxalate. Adequate hydration promotes frequent urination, which helps flush out these minerals. Limiting fluid intake (choice A) can lead to concentrated urine and increase the risk of stone formation. Increasing calcium intake (choice C) can actually help prevent calcium oxalate stones, as calcium binds with oxalate in the intestines, reducing its absorption. Avoiding all citrus juices (choice D) is unnecessary, as they do not directly contribute to the formation of calcium oxalate stones.
While assessing a client who is receiving continuous IV therapy via his left forearm, a nurse notes that the site is red, swollen, and painful and that the surrounding tissues are hard. Which of the following actions should the nurse take first?
- A. Discontinue the existing IV line
- B. Apply warm compresses
- C. Elevate the extremity
- D. Notify the healthcare provider
Correct Answer: A
Rationale: The correct action is to discontinue the existing IV line first. This is crucial because the client is exhibiting signs of infiltration, which can lead to tissue damage and complications. By removing the IV line, further damage can be prevented. Applying warm compresses or elevating the extremity may not address the underlying issue and could potentially worsen the condition. Notifying the healthcare provider is important but should not be the first step in this situation.
A nurse is assessing a client who has disseminated intravascular coagulation (DIC). Which of the following findings should the nurse expect?
- A. Excessive thrombosis and bleeding
- B. Clotting of the mucous membranes
- C. Increase in platelet count
- D. Excessive red blood cell count
Correct Answer: A
Rationale: The correct answer is A: Excessive thrombosis and bleeding. In DIC, there is a widespread activation of the clotting cascade leading to formation of microthrombi, causing excessive clotting. However, as the clotting factors are depleted, bleeding can occur. This results in a paradoxical situation of both thrombosis and bleeding. B is incorrect as clotting of mucous membranes is not specific to DIC. C is incorrect as platelet count is usually decreased in DIC due to consumption. D is incorrect as excessive red blood cell count is not a characteristic of DIC.
