1. What are the primary causes of respiratory acidosis?
- A. Hypoventilation and lung disease
- B. Hyperventilation and pneumonia
- C. Increased oxygen saturation and tachypnea
- D. Dehydration and hypoxia
Correct answer: A
Rationale: The correct answer is A: Hypoventilation and lung disease. Respiratory acidosis occurs when there is an accumulation of CO2 in the body due to inadequate ventilation. Hypoventilation, which reduces the elimination of CO2, and lung diseases that impair gas exchange are the primary causes. Choice B is incorrect because hyperventilation, not hypoventilation, leads to respiratory alkalosis, not acidosis. Choice C is incorrect because increased oxygen saturation and tachypnea do not directly cause respiratory acidosis. Choice D is incorrect as dehydration and hypoxia do not typically lead to respiratory acidosis.
2. A charge nurse on a medical-surgical unit is planning assignments for a licensed practical nurse (LPN) who has been sent from the postpartum unit due to a staffing shortage for the shift. Which of the following client assignments should the nurse delegate to the LPN?
- A. A client who is postoperative following a bowel resection with an NGT set to continuous suction.
- B. A client who has fractured a femur yesterday and is experiencing shortness of breath.
- C. A client who sustained a concussion and has unequal pupils.
- D. A client who has an Hgb of 6.3 g/dl and a prescription for packed RBCs.
Correct answer: A
Rationale: The correct answer is A because the LPN can care for stable clients with complex needs, such as managing an NGT set to continuous suction. Choices B, C, and D involve clients with more acute conditions that require a higher level of assessment and intervention, making them unsuitable for delegation to an LPN. Choice B requires prompt evaluation of the shortness of breath in a client with a recent femur fracture, which is beyond the LPN's scope. Choice C involves a head injury and unequal pupils, indicating the need for neurological assessment and close monitoring. Choice D relates to a critically low hemoglobin level and the need for blood transfusion, requiring careful monitoring and potential intervention beyond the LPN's role.
3. A client who is to undergo a colonoscopy is being taught by a nurse about the procedure. Which of the following statements by the client indicates an understanding of the teaching?
- A. I will drink liquids right up until the procedure.
- B. I will need to stop eating and drinking at least 24 hours before the procedure.
- C. I will be sedated and will not feel any pain during the procedure.
- D. I will not need to follow any specific dietary restrictions for this procedure.
Correct answer: C
Rationale: Choice C is the correct answer. During a colonoscopy, clients are typically sedated, so they do not feel any pain during the procedure. Choices A, B, and D are incorrect. Clients are usually required to stop eating and drinking at least 24 hours before a colonoscopy, and there are specific dietary restrictions that need to be followed before the procedure to ensure a successful examination.
4. What is the priority for a client with dehydration?
- A. Administer antiemetics to prevent nausea
- B. Monitor electrolyte levels to prevent imbalances
- C. Administer oral rehydration solutions
- D. Administer intravenous fluids
Correct answer: B
Rationale: The priority for a client with dehydration is to monitor electrolyte levels to prevent imbalances. Dehydration can lead to electrolyte disturbances, which can have serious consequences. Administering antiemetics (Choice A) may help with nausea but does not address the root cause of dehydration. Administering oral rehydration solutions (Choice C) can be beneficial, but monitoring electrolyte levels is crucial in managing dehydration. Administering intravenous fluids (Choice D) is important in severe cases of dehydration, but monitoring electrolytes should come first to assess the extent of the imbalance and guide fluid replacement therapy effectively.
5. A nurse on an acute unit has received a change of shift report for 4 clients. Which of the following clients should the nurse assess first?
- A. A client who is 1 hr postoperative and has hypoactive bowel sounds.
- B. A client who has a fractured left tibia and pallor in the affected extremity.
- C. A client who had a cardiac catheterization 3 hr ago and has 3+ pedal pulses.
- D. A client who has an elevated AST level following the administration of azithromycin.
Correct answer: B
Rationale: The correct answer is B because pallor in an extremity after a fracture could indicate compromised circulation, making it a priority for assessment. Choice A is not the priority as hypoactive bowel sounds in a client 1 hr postoperative, while concerning, do not indicate a life-threatening condition. Choice C, a client who had a cardiac catheterization 3 hr ago and has 3+ pedal pulses, indicates good perfusion and does not require immediate attention. Choice D, a client with an elevated AST level following the administration of azithromycin, may require further assessment but is not as urgent as the client with potential compromised circulation in choice B.
