1. A nurse is caring for an older, immobile patient whose condition requires a supine position. Which metabolic alteration will the nurse monitor for in this patient?
- A. Increased appetite
- B. Increased diarrhea
- C. Increased metabolic rate
- D. Increased pulse rate
Correct answer: D
Rationale: When an older, immobile patient is in a supine position, it increases cardiac workload, leading to an increased pulse rate. This is because the heart rate in older adults may not tolerate the additional workload. Choices A, B, and C are incorrect because an increased appetite, increased diarrhea, and increased metabolic rate are not directly associated with being immobile in a supine position. Increased appetite is more related to nutritional needs or certain medical conditions, increased diarrhea could be due to various causes, and an increased metabolic rate is not typically a direct consequence of lying supine.
2. A nurse at an assisted living facility is preparing an in-service for residents about electrical safety. Which of the following instructions should the nurse include?
- A. Avoid taping electrical cords to the floor.
- B. Clean electrical equipment before disconnection.
- C. Cover exposed wires with tape before use.
- D. Disconnect electrical equipment by grasping the plug.
Correct answer: A
Rationale: The correct instruction for electrical safety is to avoid taping electrical cords to the floor. Taping cords can create tripping hazards, leading to falls and potential injuries. Choice B, cleaning electrical equipment before disconnection, is not directly related to electrical safety but rather to equipment maintenance. Choice C, covering exposed wires with tape before use, is incorrect as exposed wires should be properly insulated and repaired by a qualified professional. Choice D, disconnecting electrical equipment by grasping the plug, is unsafe and can lead to electrical shocks. It is always recommended to unplug devices by holding the plug itself, not by pulling the cord.
3. A healthcare professional is reviewing a client's fluid and electrolyte status. Which of the following findings should the healthcare professional report to the provider?
- A. BUN 15 mg/dL
- B. Creatinine 0.8 mg/dL
- C. Sodium 143 mEq/L
- D. Potassium 5.4 mEq/L
Correct answer: D
Rationale: The correct answer is D. A potassium level of 5.4 mEq/L is above the expected reference range, indicating hyperkalemia. Hyperkalemia can lead to serious complications such as dysrhythmias, making it important for the healthcare professional to report this finding to the provider for further evaluation and intervention. Choices A, B, and C fall within normal ranges and do not pose an immediate risk to the client's health, so they would not warrant immediate reporting to the provider. Elevated BUN or creatinine levels may indicate kidney dysfunction, while a sodium level of 143 mEq/L falls within the normal range for adults and does not typically require urgent intervention.
4. The healthcare provider is preparing to administer a subcutaneous injection of heparin. Which site is most appropriate for the healthcare provider to use?
- A. Deltoid muscle
- B. Ventrogluteal site
- C. Abdomen
- D. Dorsogluteal site
Correct answer: C
Rationale: The abdomen is the most appropriate site for administering subcutaneous heparin injections. The abdomen has a layer of subcutaneous fat and a good blood supply, making it an ideal site for subcutaneous injections. Using the deltoid muscle for heparin injections is not appropriate as it is typically used for intramuscular injections. The ventrogluteal site is more suitable for intramuscular injections rather than subcutaneous injections. The dorsogluteal site is no longer recommended for injections due to the risk of injury to the sciatic nerve.
5. The healthcare provider is assessing a client who has a chest tube in place following a pneumothorax. Which finding should be reported to the healthcare provider immediately?
- A. Bubbling in the water seal chamber
- B. Drainage greater than 70 ml/hour
- C. Tidaling in the water seal chamber
- D. Absence of breath sounds on the affected side
Correct answer: D
Rationale: The absence of breath sounds on the affected side is a critical finding that may indicate a tension pneumothorax, a life-threatening condition requiring immediate intervention. This situation can lead to a shift of the mediastinum and impaired ventilation. Bubbling in the water seal chamber is an expected finding in a chest tube drainage system and indicates proper functioning. Drainage greater than 70 ml/hour is a concern but does not require immediate reporting unless it continues at a high rate or is associated with other symptoms. Tidaling in the water seal chamber is a normal fluctuation and indicates the chest tube system is patent and functioning correctly.
