1. The healthcare professional is preparing to administer a blood transfusion to a client with anemia. Which action is most important to prevent a transfusion reaction?
- A. Check the client's vital signs before starting the transfusion.
- B. Use a blood filter when administering the transfusion.
- C. Verify the blood type and Rh factor with another healthcare professional.
- D. Administer antihistamines before starting the transfusion.
Correct answer: C
Rationale: Verifying the blood type and Rh factor with another healthcare professional is the most crucial action to prevent a transfusion reaction. Ensuring compatibility between the donor blood and the recipient is essential in preventing adverse reactions such as hemolytic transfusion reactions. Checking vital signs is important for monitoring the client during the transfusion process but does not directly prevent a transfusion reaction. Using a blood filter can help remove clots and debris but does not address the risk of a reaction due to blood type incompatibility. Administering antihistamines before the transfusion is not a standard practice to prevent transfusion reactions related to blood type incompatibility.
2. A client with a history of hypertension is admitted with shortness of breath and chest pain. Which diagnostic test should the nurse anticipate preparing the client for first?
- A. Electrocardiogram (ECG)
- B. Chest X-ray
- C. Pulmonary function tests (PFTs)
- D. Arterial blood gases (ABGs)
Correct answer: A
Rationale: The correct answer is A: Electrocardiogram (ECG). An ECG should be performed first to assess for cardiac ischemia in a client presenting with shortness of breath and chest pain. This test helps in evaluating the electrical activity of the heart and can identify signs of myocardial infarction or other cardiac issues. Choice B, Chest X-ray, may be ordered after the ECG to assess for pulmonary conditions like pneumonia or effusions. Choice C, Pulmonary function tests (PFTs), are used to evaluate lung function and are not the primary diagnostic tests for a client with symptoms of cardiac origin. Choice D, Arterial blood gases (ABGs), may provide information about oxygenation but are not the initial test indicated for a client with suspected cardiac issues.
3. A client is taking levothyroxine (Synthroid) for hypothyroidism. Which symptom would indicate to the nurse that the client is taking too much medication?
- A. Bradycardia
- B. Lethargy
- C. Tremors
- D. Constipation
Correct answer: C
Rationale: When a client is taking an excessive dose of levothyroxine (Synthroid), it can lead to symptoms of hyperthyroidism. Tremors are a common sign of excessive medication, along with tachycardia and insomnia. Bradycardia, lethargy, and constipation are typical symptoms of hypothyroidism, indicating that the client may require a higher dose of levothyroxine rather than too much.
4. The nurse is caring for a patient with a massive burn injury and possible hypovolemia. Which assessment data will be of most concern to the nurse?
- A. Blood pressure is 90/40 mm Hg.
- B. Urine output is 30 mL over the last hour.
- C. Oral fluid intake is 100 mL over the last 8 hours.
- D. There is prolonged skin tenting over the sternum.
Correct answer: A
Rationale: The correct answer is A: "Blood pressure is 90/40 mm Hg." A low blood pressure reading of 90/40 mm Hg indicates that the patient may be developing hypovolemic shock due to intravascular fluid loss from the burn injury. This finding is of utmost concern as it suggests systemic hypoperfusion, requiring immediate intervention to prevent complications. Choices B, C, and D also indicate signs of dehydration and the need to increase fluid intake; however, they are not as urgent as addressing the hypotension and potential shock presented in choice A.
5. A female client with a history of chronic obstructive pulmonary disease (COPD) is being treated at home and is currently receiving oxygen at 2 liters via nasal cannula. The spouse, who is the caregiver, reports that the client requires assistance when ambulating short distances, including going to the bathroom. Which suggestion should the health care nurse provide to the caregiver?
- A. disconnect oxygen when ambulating to the bathroom
- B. administer a breathing treatment prior to ambulation
- C. suggest obtaining a bedside commode for toileting
- D. ask for additional assistance to reduce the risk of falls
Correct answer: C
Rationale: For a client with COPD requiring assistance for short-distance ambulation, suggesting a bedside commode for toileting is the most appropriate intervention. This recommendation helps reduce the need for the client to walk long distances, thereby minimizing the risk of exertion and potential falls. Disconnecting oxygen during ambulation (Choice A) is not safe for a client with COPD, as oxygen therapy should be continuous. Administering a breathing treatment before ambulation (Choice B) may not directly address the client's need for assistance with toileting. Asking for additional assistance (Choice D) can be beneficial but providing a bedside commode specifically addresses the current issue of ambulating short distances for toileting.
