What are the key signs of hyperkalemia and how should it be treated?
- A. Elevated potassium levels, muscle weakness; administer calcium gluconate
- B. Decreased potassium levels, confusion; administer potassium chloride
- C. Elevated sodium levels, bradycardia; administer sodium bicarbonate
- D. Low sodium levels, muscle cramps; administer sodium chloride
Correct Answer: A
Rationale: The correct signs of hyperkalemia include elevated potassium levels and muscle weakness. The treatment involves administering calcium gluconate to help stabilize the heart. Choice B is incorrect as hyperkalemia is characterized by elevated, not decreased, potassium levels. Choice C is incorrect as hyperkalemia does not involve elevated sodium levels, and the treatment is not sodium bicarbonate. Choice D is incorrect as hyperkalemia does not lead to low sodium levels, and sodium chloride is not the treatment for hyperkalemia.

A nurse is caring for a client who is 1 hr postoperative following rhinoplasty. Which of the following manifestations requires immediate action by the nurse?
- A. Increase in frequency of swallowing.
- B. Moderate sanguineous drainage on the drip pad.
- C. Bruising to the face.
- D. Absent gag reflex.
Correct Answer: A
Rationale: The correct answer is A: Increase in frequency of swallowing. After rhinoplasty, an increase in frequency of swallowing may indicate possible bleeding, which requires immediate action by the nurse. The client could be experiencing postoperative bleeding, and prompt intervention is necessary to prevent complications. Choice B, moderate sanguineous drainage on the drip pad, is expected in the immediate postoperative period and does not require immediate action unless it becomes excessive. Choice C, bruising to the face, is a common postoperative finding and does not require immediate action unless it is excessive or affects the airway. Choice D, absent gag reflex, would not be expected immediately following rhinoplasty and would require intervention, but the manifestation of increased swallowing frequency is a higher priority due to its association with potential bleeding.
A nurse is caring for a client who is experiencing post-traumatic stress disorder (PTSD). Which of the following manifestations should the nurse expect?
- A. Hyperactivity
- B. Hypervigilance
- C. Restlessness
- D. Avoidance of social situations
Correct Answer: B
Rationale: The correct answer is B: Hypervigilance. Individuals with PTSD often experience hypervigilance, which involves being overly alert, easily startled, and constantly scanning their environment for potential threats. This heightened state of awareness is a common response to the trauma experienced. Choices A, C, and D are incorrect. Hyperactivity is not typically a primary manifestation of PTSD; restlessness may occur but is not as characteristic as hypervigilance, and although avoidance of social situations can be a symptom of PTSD, hypervigilance is more directly associated with the disorder.
What is a primary symptom of left-sided heart failure?
- A. Shortness of breath
- B. Edema
- C. Rapid heartbeat
- D. Confusion
Correct Answer: A
Rationale: Shortness of breath is a primary symptom of left-sided heart failure. In this condition, the heart's inability to pump effectively leads to fluid backing up into the lungs, causing difficulty breathing. Edema (swelling), rapid heartbeat, and confusion are more commonly associated with other conditions or right-sided heart failure. Edema is often seen in right-sided heart failure due to fluid accumulation in the body, rapid heartbeat can be a general sign of heart issues, and confusion is more related to decreased brain perfusion in severe heart failure cases.
A nurse is contributing to the plan of care for a client who has a chest tube connected to a closed drainage system. Which of the following interventions should the nurse include?
- A. Clamp the chest tube
- B. Maintain the drainage below the level of the chest
- C. Elevate the chest tube above chest level
- D. Avoid frequent dressing changes
Correct Answer: B
Rationale: The correct intervention for a client with a chest tube connected to a closed drainage system is to maintain the drainage below the level of the chest. This position allows proper drainage of fluids and helps prevent complications such as backflow of blood or fluids into the chest cavity. Clamping the chest tube (Choice A) is incorrect as it can lead to a tension pneumothorax. Elevating the chest tube above chest level (Choice C) is also incorrect because it can impede proper drainage. Avoiding frequent dressing changes (Choice D) is important to prevent introducing infection, but it is not directly related to the position of the drainage system.
A client is learning to use a cane. What instruction is essential for this client?
- A. Advance the cane and the weaker leg at the same time
- B. Maintain two points of support on the ground at all times
- C. Use the cane on the weaker side for better support
- D. Advance the cane 30 to 45 cm with each step
Correct Answer: B
Rationale: The correct instruction for a client learning to use a cane is to maintain two points of support on the ground at all times. This ensures better stability and reduces the risk of falls. Choice A is incorrect because advancing the cane and the weaker leg simultaneously may lead to imbalance. Choice C is incorrect because the cane should be used on the stronger side to provide support. Choice D is incorrect because there is no specific measurement for advancing the cane with each step, and the focus should be on maintaining stability.
