1. A patient with schizophrenia is prescribed risperidone. The nurse should monitor the patient for which common side effect of this medication?
- A. Agranulocytosis
- B. Weight gain
- C. Hair loss
- D. Hyperthyroidism
Correct answer: B
Rationale: When a patient is prescribed risperidone, an atypical antipsychotic, the nurse should monitor for weight gain as it is a common side effect of this medication. Weight gain can occur due to metabolic changes and increased appetite associated with risperidone use. Agranulocytosis is a severe decrease in a type of white blood cells, and it is not a common side effect of risperidone. Hair loss and hyperthyroidism are also not typically associated with risperidone use.
2. What ECG changes are seen with hyperkalemia?
- A. Flattened T waves
- B. Elevated ST segments
- C. Prominent U waves
- D. Widened QRS complex
Correct answer: A
Rationale: Flattened T waves are an early ECG sign of hyperkalemia. Hyperkalemia affects the repolarization phase of the cardiac action potential, leading to changes such as peaked T waves, prolonged PR interval, widened QRS complex, and ultimately sine wave pattern. Elevated ST segments, prominent U waves, and widened QRS complex are not typically associated with hyperkalemia, making choices B, C, and D incorrect.
3. A forensic nurse is using the epidemiological triangle to explain factors that contribute to violent behavior. Which of the following factors should the nurse identify as an environmental factor in the epidemiological triangle?
- A. Crowded living conditions
- B. Traumatic brain injury
- C. Alzheimer's disease
- D. Impaired coping abilities
Correct answer: A
Rationale: Crowded living conditions are considered an environmental factor in the epidemiological triangle as they can contribute to the spread of violence. In this context, environmental factors refer to external influences such as social and physical environments. Traumatic brain injury, Alzheimer's disease, and impaired coping abilities are not typically classified as environmental factors in the epidemiological triangle. Traumatic brain injury and Alzheimer's disease are more related to individual health conditions, while impaired coping abilities are more focused on individual psychological factors rather than external environmental influences.
4. What is the major effect of filgrastim (Neupogen) in a patient with chronic renal failure?
- A. Decreases neutropenia related to chemotherapy
- B. Decreases white blood cells related to infection
- C. Decreases growth of blood vessels due to ischemia
- D. Decreases platelet count related to bleeding
Correct answer: A
Rationale: The major effect of filgrastim (Neupogen) is to stimulate the production of neutrophils, thereby decreasing neutropenia in patients undergoing chemotherapy. This medication helps the bone marrow produce more white blood cells, specifically neutrophils, to reduce the risk of infections associated with low neutrophil counts. Choices B, C, and D are incorrect because filgrastim does not decrease white blood cells related to infection, growth of blood vessels, or platelet count related to bleeding.
5. Which intervention is most effective for managing a patient with constipation?
- A. Increase the patient's fluid intake.
- B. Administer a stool softener as prescribed.
- C. Provide the patient with a high-fiber diet.
- D. Teach the patient to perform Valsalva maneuvers.
Correct answer: B
Rationale: The most effective intervention for managing constipation in a patient is to administer a stool softener as prescribed. Stool softeners help relieve constipation by making the stool easier to pass, especially in postoperative patients. Increasing fluid intake can be beneficial but may not address the underlying cause of constipation. While a high-fiber diet is important for bowel health, it may not provide immediate relief for constipation. Teaching a patient to perform Valsalva maneuvers is not recommended for managing constipation as it can lead to adverse effects like increasing intra-abdominal pressure.
