A post-operative client is prescribed sequential compression devices (SCDs) while on bed rest. What is the primary purpose of this device?
- A. To prevent deep vein thrombosis (DVT).
- B. To improve circulation in the legs.
- C. To prevent pressure ulcers.
- D. To alleviate post-operative pain.
Correct Answer: A
Rationale: The correct answer is A: 'To prevent deep vein thrombosis (DVT).' Sequential compression devices (SCDs) are primarily used to prevent deep vein thrombosis (DVT) by promoting blood flow in the legs and reducing venous stasis, which is a common risk for post-operative clients who are on bed rest. While SCDs do improve circulation in the legs indirectly, their primary purpose is DVT prevention. Preventing pressure ulcers is typically achieved through repositioning and support surfaces, not with SCDs, making choice C incorrect. SCDs are not used to alleviate post-operative pain, so choice D is also incorrect.

The PN is caring for a client who had an acute brain attack with resulting expressive aphasia and urinary incontinence. To ensure care for the client, which task should the PN delegate to the UAP?
- A. Explain how to use a communication board
- B. Document progress in the use of the communication board
- C. Encourage voiding by assisting the client to the bedside commode
- D. Establish a bladder training schedule and methods
Correct Answer: C
Rationale: Assisting the client to the bedside commode is an appropriate task for the UAP as it involves basic patient care and mobility assistance, which are within the UAP's scope of practice. Options A and B involve communication techniques and documentation, which are more appropriate for licensed nursing staff. Option D involves establishing a bladder training schedule, which requires assessment and planning skills beyond the UAP's role.
A client with a prescription for a transcutaneous electrical nerve stimulator (TENS) unit for pain management asks how it works. What information should the nurse reinforce?
- A. The discharge of electricity will distract the client's focus from the pain
- B. An infusion of medication in the spinal canal will block pain perception
- C. Pain perception in the cerebral cortex is dulled by the unit's discharge of an electrical stimulus
- D. A mild electrical stimulus on the skin surface closes the gates of nerve conduction for severe pain
Correct Answer: D
Rationale: The correct answer is D. TENS works by delivering a mild electrical stimulus that can block pain signals from reaching the brain, effectively reducing the perception of pain. Choice A is incorrect because TENS does not distract from pain but rather interferes with pain signals. Choice B is incorrect as TENS does not involve infusing medication into the spinal canal. Choice C is also incorrect because TENS does not target the cerebral cortex to dull pain perception but rather works at the level of nerve conduction.
The PN administered darbepoetin alfa to a client with chronic kidney disease (CKD). Which serum laboratory value should the PN monitor to assess the effectiveness of this drug?
- A. Calcium
- B. Phosphorus
- C. Hemoglobin
- D. White blood cell count
Correct Answer: C
Rationale: Darbepoetin alfa is used to stimulate red blood cell production in clients with CKD. Monitoring hemoglobin levels is essential to assess the effectiveness of the treatment and to adjust the dosage to avoid complications such as hypertension or thrombosis. Monitoring calcium (Choice A), phosphorus (Choice B), or white blood cell count (Choice D) is not directly related to the effectiveness of darbepoetin alfa in treating anemia associated with CKD.
An older male client with Alzheimer's disease is admitted to an extended care facility. Which intervention should the PN include in the client's nursing care plan?
- A. Plan to have the same nursing staff provide care for the client whenever possible
- B. Describe the activities available to residents and encourage him to choose the ones he prefers
- C. Encourage the client to remain on the unit for three weeks until he is oriented to his new surroundings
- D. Introduce the client to the nursing staff and other residents as soon as possible
Correct Answer: A
Rationale: The correct intervention for a client with Alzheimer's disease in an extended care facility is to plan to have the same nursing staff provide care whenever possible. Consistency in caregivers helps reduce confusion and anxiety in clients with Alzheimer's disease, promoting a stable and supportive environment for the client. Choice B is incorrect as it focuses on activities rather than the consistency of caregivers. Choice C is incorrect as it suggests isolating the client, which can lead to increased confusion and distress. Choice D is incorrect as introducing the client to new people immediately can be overwhelming and may exacerbate their symptoms.
During the last 30 days, an elderly client has exhibited a progressively decreasing appetite, is spending increasing amounts of daytime hours in bed, and refuses to participate in planned daytime activities. Which action should the practical nurse take?
- A. Record the findings and report the symptoms to the charge nurse
- B. Ask the family members to visit more often to stimulate the patient
- C. Motivate the client by offering favorite foods as a prize
- D. Withhold any medications that may cause side effects
Correct Answer: A
Rationale: The practical nurse should record the findings and report the symptoms to the charge nurse. These behaviors may indicate a serious underlying condition such as depression or physical illness. By reporting to the charge nurse, the client can receive appropriate assessment and intervention promptly. Choice B is incorrect as family visits may not address the root cause of the symptoms. Choice C is incorrect as it oversimplifies the situation and may not be effective in addressing the underlying issue. Choice D is incorrect because withholding medications without proper assessment and guidance can be harmful to the client's health.
