1. A mother brings her 13-month-old child with Down Syndrome to a pediatric clinic reporting muscle weakness and poor movement. The child's reflexes are noted to be diminished. Which action should the nurse take first?
- A. Contact the physician immediately
- B. Have the patient go for an X-ray for a c-spine work-up
- C. Start an IV on the patient
- D. Position the child's neck in a neutral position
Correct answer: D
Rationale: In a child with Down Syndrome presenting with muscle weakness and diminished reflexes, an atlanto-axial dislocation is a concern. The priority action is to position the child's neck in a neutral c-spine posture to prevent further injury. This should be done before any movement or manipulation. Contacting the physician should follow to ensure appropriate evaluation and management. Initiating an IV is not indicated unless specifically ordered for a medical reason. Ordering an X-ray for a c-spine work-up should not be the first action as it may involve movement that could exacerbate the condition if an injury is present.
2. The nurse has just received a change-of-shift report. Which client should the nurse assess first?
- A. A client 2 hours post-lobectomy with 150cc drainage
- B. A client 2 days post-gastrectomy with scant drainage
- C. A client with pneumonia with an oral temperature of 102�F
- D. A client with a fractured hip in Buck's traction
Correct answer: A
Rationale: The nurse should assess the client 2 hours post-lobectomy with 150cc drainage first because postoperative assessments are crucial during the immediate postoperative period. This client may be at higher risk for complications, such as bleeding or infection, requiring immediate attention. Clients in choices B, C, and D are relatively stable and can be assessed after the immediate postoperative client has been evaluated.
3. A client who is newly diagnosed with Parkinson's disease and beginning medication therapy asks the nurse, 'How soon will I see improvement?' The nurse's best response is:
- A. "That varies from client to client."?
- B. "You should discuss that with your physician."?
- C. "You should notice a difference in a few days."?
- D. "It might take several weeks before you notice improvement."?
Correct answer: D
Rationale: In the case of Parkinson's disease, improvement in symptoms may take several weeks of therapy to become noticeable. Therefore, the correct answer is to inform the client that it might take several weeks before they notice improvement. Choice A acknowledges individual variability but does not provide a specific timeframe, making it less reassuring. Choice B suggests deferring the question to the physician, which is not the most supportive response. Choice C is incorrect because improvement in Parkinson's disease symptoms typically does not occur within a few days.
4. Which of the following medications is a serotonin antagonist that might be used to relieve nausea and vomiting?
- A. metoclopramide (Reglan)
- B. ondansetron (Zofran)
- C. hydroxyzine (Vistaril)
- D. prochlorperazine (Compazine)
Correct answer: B
Rationale: Zofran is a serotonin antagonist that can be used to relieve nausea and vomiting. Ondansetron (Zofran) works by blocking serotonin receptors in the chemoreceptor trigger zone (CTZ) and the gastrointestinal tract. This action helps reduce nausea and vomiting. Metoclopramide (Reglan) works as a dopamine antagonist and also has prokinetic effects, making it effective for different conditions. Hydroxyzine (Vistaril) is an antihistamine with antiemetic properties, but it does not act as a serotonin antagonist. Prochlorperazine (Compazine) is a dopamine antagonist that is also used to treat nausea and vomiting, but not as a serotonin antagonist like ondansetron.
5. Which statement best describes electrolytes in intracellular and extracellular fluid?
- A. There is a greater concentration of sodium in extracellular fluid and potassium in intracellular fluid
- B. There is an equal concentration of sodium and potassium in extracellular fluid
- C. There is a greater concentration of potassium in extracellular fluid and sodium in intracellular fluid
- D. There is an equal concentration of sodium and potassium between intracellular and extracellular fluid
Correct answer: A
Rationale: Electrolytes are distributed unequally between intracellular and extracellular fluids. Sodium concentration is higher in extracellular fluid, while potassium concentration is higher in intracellular fluid. Therefore, the correct answer is 'There is a greater concentration of sodium in extracellular fluid and potassium in intracellular fluid.' Choices B, C, and D are incorrect because they do not accurately describe the typical distribution of sodium and potassium between intracellular and extracellular fluid.
