1. After a motor vehicle collision, a client is admitted to the medical unit with acute adrenal insufficiency (Addisonian crisis). Which prescription should the nurse implement?
- A. Determine serum glucose levels
- B. Withhold potassium additives to IV fluids
- C. Give IV corticosteroid replacement
- D. Prepare to initiate IV vasopressors
Correct answer: C
Rationale: In a client with acute adrenal insufficiency (Addisonian crisis) following a motor vehicle collision, the priority intervention is to administer IV corticosteroid replacement. This is crucial to manage the crisis by replacing the deficient cortisol. Determining serum glucose levels (Choice A) may be important but is not the immediate priority in this situation. Withholding potassium additives to IV fluids (Choice B) is not indicated and may exacerbate electrolyte imbalances. Initiating IV vasopressors (Choice D) is not the primary treatment for acute adrenal insufficiency and should be reserved for managing hypotension that is unresponsive to corticosteroid therapy.
2. A client with major depression who is taking fluoxetine calls the psychiatric clinic reporting being more agitated, irritable, and anxious than usual. Which intervention should the nurse implement?
- A. Tell the client to have a complete blood count (CBC) drawn
- B. Instruct the client to seek medical attention immediately
- C. Encourage them to take the medication at night with a snack
- D. Explain that these are common side effects of the medication
Correct answer: B
Rationale: Increased agitation, irritability, and anxiety can be signs of serotonin syndrome or other serious side effects, not common side effects of fluoxetine. Instructing the client to seek medical attention immediately is crucial to address any potential serious adverse reactions. Option A is unnecessary as a CBC would not address the symptoms described. Option C is not the priority when serious side effects are suspected. Option D is incorrect as these symptoms should not be dismissed as common side effects.
3. Following the evacuation of a subdural hematoma, an older adult develops an infection. The client is transferred to the neuro intensive care unit with a temperature of 101.8 F (39.3 C) axillary, pulse of 180 beats/minute, and a blood pressure of 90/60 mmHg. What is the priority intervention to include in this client’s plan of care?
- A. Confusion
- B. Check neuro vital signs every 4 hours.
- C. Maintain intravenous access.
- D. Keep the suture line clean and dry.
Correct answer: C
Rationale: The priority intervention for the client in this scenario is to maintain intravenous (IV) access. Given the client's condition with infection, elevated temperature, tachycardia, and hypotension, it is crucial to ensure IV access for administering antibiotics, fluids, and other medications promptly. This can help manage the infection, stabilize hemodynamics, and support the client's hydration and medication needs. Checking neuro vital signs, although important, is secondary to addressing the immediate need for IV access. Keeping the suture line clean and dry is important for wound care but not the priority when dealing with a systemic infection and hemodynamic instability.
4. A client has a blood glucose level of 70 mg/dl and reports feeling shaky and weak. What is the best initial action by the nurse?
- A. Obtain a fingerstick glucose reading
- B. Administer 15 grams of a fast-acting carbohydrate
- C. Perform a quick assessment of the client’s neuro status
- D. Provide a glass of milk and monitor the client’s symptoms
Correct answer: B
Rationale: Administering 15 grams of a fast-acting carbohydrate is the best initial action to address hypoglycemia symptoms promptly by raising blood glucose levels. This intervention is crucial to prevent further deterioration in the client's condition. Obtaining a fingerstick glucose reading is important but may delay treatment. Performing a quick assessment of the client's neuro status is secondary to addressing the immediate low blood glucose levels. Providing a glass of milk is not the recommended first-line treatment for hypoglycemia; fast-acting carbohydrates are preferred to rapidly increase blood sugar levels.
5. For a client with pneumonia, the prescription states, “Oxygen at liters/min per nasal cannula PRN difficult breathing.” Which nursing intervention is effective in preventing oxygen toxicity?
- A. Avoiding the administration of oxygen at high levels for extended periods.
- B. Administering a sedative at bedtime to slow the client’s respiratory rate.
- C. Removing the nasal cannula during the night to prevent oxygen buildup.
- D. Running oxygen through a hydration source prior to administration.
Correct answer: A
Rationale: Choice A is the correct answer because prolonged exposure to high levels of oxygen can lead to oxygen toxicity. Administering oxygen at high levels for extended periods can overwhelm the body's natural defenses against high oxygen levels, causing toxicity. Choices B, C, and D are incorrect. Choice B is unrelated to preventing oxygen toxicity. Choice C is unsafe as removing the nasal cannula can deprive the client of necessary oxygen. Choice D, running oxygen through a hydration source, is not a standard practice for preventing oxygen toxicity.
