1. What are the expected changes on an ECG for a patient with hypokalemia?
- A. Flattened T waves
- B. Prominent U waves
- C. ST elevation
- D. Wide QRS complexes
Correct answer: A
Rationale: Flattened T waves are an early sign of hypokalemia on an ECG. Hypokalemia primarily manifests as flattened T waves on an ECG. While prominent U waves can be seen in hypokalemia, they are not as specific as flattened T waves. ST elevation is more commonly associated with conditions like myocardial infarction rather than hypokalemia. Wide QRS complexes are typically not a feature of hypokalemia on an ECG.
2. What are the characteristics of a thrombotic stroke?
- A. Gradual onset over minutes to hours
- B. Numbness on one side of the body
- C. Associated with a loss of consciousness
- D. Associated with seizures and convulsions
Correct answer: A
Rationale: The correct answer is A. Thrombotic strokes typically have a gradual onset over minutes to hours as they result from a clot obstructing blood flow. Choice B, numbness on one side of the body, is more commonly associated with an ischemic stroke rather than specifically a thrombotic stroke. Choice C, loss of consciousness, is not a defining characteristic of a thrombotic stroke. Choice D, seizures and convulsions, are more commonly seen in hemorrhagic strokes rather than thrombotic strokes.
3. What is the priority action if a patient experiences abdominal cramping during enema administration?
- A. Lower the height of the solution container
- B. Increase the flow of the enema solution
- C. Stop the procedure and remove the tubing
- D. Continue the enema at a slower rate
Correct answer: A
Rationale: During enema administration, if a patient experiences abdominal cramping, the priority action is to lower the height of the solution container. This adjustment can help relieve abdominal cramping by reducing the flow rate of the enema, making it more comfortable for the patient. Increasing the flow of the enema solution (Choice B) can exacerbate the cramping. Stopping the procedure and removing the tubing (Choice C) may be necessary in some cases of severe discomfort or complications, but adjusting the height of the solution container should be the initial response. Continuing the enema at a slower rate (Choice D) may not address the immediate need to alleviate the cramping.
4. What is the priority action if a patient experiences hypoglycemia after an insulin dose?
- A. Check the patient's blood glucose level
- B. Administer IV dextrose
- C. Document the incident
- D. Continue monitoring the patient
Correct answer: A
Rationale: The priority action when a patient experiences hypoglycemia after an insulin dose is to check the patient's blood glucose level. This is crucial to confirm hypoglycemia before initiating any treatment. While administering IV dextrose may be necessary if the patient's blood glucose level is critically low, confirming hypoglycemia is essential to guide appropriate interventions. Documenting the incident is important for documentation purposes but is not the immediate priority when the patient's safety is at risk. Continuing to monitor the patient is essential, but it should follow the confirmation and initial management of hypoglycemia.
5. What is the priority lab value for monitoring a patient with HIV?
- A. CD4 T-cell count below 180 cells/mm3
- B. Serum albumin levels
- C. White blood cell count
- D. Hemoglobin levels
Correct answer: A
Rationale: The correct answer is A: CD4 T-cell count below 180 cells/mm3. Monitoring the CD4 T-cell count is crucial in patients with HIV as it serves as a key indicator of immune function. A count below 180 cells/mm3 indicates severe immunocompromise and an increased risk of opportunistic infections. Choice B, serum albumin levels, though important for assessing nutritional status, is not the priority lab value for HIV monitoring. Choice C, white blood cell count, is a nonspecific measure of immune function and may not accurately reflect the status of the immune system in HIV patients. Choice D, hemoglobin levels, are essential for evaluating anemia but are not the primary lab value for monitoring HIV.
