1. A client has a prescription for a Transcutaneous Electrical Nerve Stimulator (TENS) unit for pain management during the postoperative period following a Lumbar Laminectomy. What information should the nurse reinforce about the action of this adjuvant pain modality?
- A. Mild electrical stimulus on the skin surface closes the gates of nerve conduction for severe pain
- B. Pain perception in the cerebral cortex is dulled by the unit's discharge of an electrical stimulus
- C. An infusion of medication in the spinal canal will block pain perception
- D. The discharge of electricity will distract the client's focus on the pain
Correct answer: A
Rationale: The correct answer is A. TENS units work by delivering small electrical impulses through the skin. These impulses are thought to close the 'gates of nerve conduction,' which can help in managing severe pain. Choice B is incorrect because the dulled pain perception does not occur in the cerebral cortex by the TENS unit. Choice C is incorrect as it describes a different method of pain management involving medication in the spinal canal. Choice D is incorrect because TENS does not work by distracting the client's focus on pain, but rather by altering pain perception through electrical impulses.
2. What is the homeostatic cellular transport mechanism that moves water from a hypotonic to a hypertonic fluid space?
- A. Filtration
- B. Diffusion
- C. Osmosis
- D. Active transport
Correct answer: C
Rationale: The correct answer is C: Osmosis. Osmosis is the homeostatic cellular transport mechanism that moves water from a hypotonic to a hypertonic fluid space to maintain cellular balance. In osmosis, water moves across a semi-permeable membrane from an area of low solute concentration (hypotonic) to an area of high solute concentration (hypertonic). This process helps regulate the water content inside cells. Choices A, B, and D are incorrect. Filtration involves the movement of solutes and solvents through a membrane due to a pressure difference, diffusion is the movement of solutes from an area of high concentration to low concentration, and active transport requires energy to move substances against their concentration gradient.
3. The nurse is assessing a client with cirrhosis who has developed ascites. What is the most important intervention to include in the care plan?
- A. Restrict sodium intake
- B. Encourage high-protein meals
- C. Increase fluid intake
- D. Administer diuretics as prescribed
Correct answer: D
Rationale: The correct answer is to administer diuretics as prescribed. Diuretics are often prescribed to help manage fluid accumulation in ascites, which is a common complication of cirrhosis. Restricting sodium intake (Choice A) is essential in managing ascites, but administering diuretics takes precedence in the care plan. Encouraging high-protein meals (Choice B) and increasing fluid intake (Choice C) are not the primary interventions for managing ascites in cirrhosis.
4. The nurse observes a client with new-onset tachycardia. What should the nurse do first?
- A. Check for the client's temperature
- B. Administer prescribed beta-blockers
- C. Assess for any chest pain or discomfort
- D. Monitor the client's blood pressure
Correct answer: C
Rationale: When a client presents with new-onset tachycardia, the first action the nurse should take is to assess for any associated symptoms like chest pain or discomfort. This is important to differentiate the potential causes of tachycardia and guide appropriate interventions. Checking the client's temperature (Choice A) may be relevant in certain situations but is not the priority when tachycardia is observed. Administering prescribed beta-blockers (Choice B) should only be done after a comprehensive assessment and healthcare provider's orders. Monitoring the client's blood pressure (Choice D) is important, but assessing for chest pain or discomfort takes precedence in this scenario to rule out cardiac causes of tachycardia.
5. The client is 4 hours post-operative from a cesarean section and complains of gas pain and bloating. What non-pharmacological intervention can the nurse provide?
- A. Encourage the client to ambulate
- B. Apply a heating pad
- C. Provide a carbonated beverage
- D. Teach relaxation techniques
Correct answer: A
Rationale: The correct answer is to encourage the client to ambulate. Early ambulation helps alleviate gas pain and bloating by promoting gastrointestinal motility and reducing the accumulation of gas in the abdomen. Applying a heating pad may provide comfort for some types of pain but is not specifically effective for gas pain. Providing a carbonated beverage can actually worsen gas pain due to the introduction of more gas into the digestive system. Teaching relaxation techniques may be beneficial for overall comfort but may not directly address the gas pain and bloating experienced post-cesarean section.
