Nursing Elites

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. A client who is 24 weeks pregnant presents with a complaint of feeling dizzy when lying on her back. What is the best response by the nurse?

• A. Advise the client to lie on her side
• B. Encourage the client to drink more fluids
• C. Suggest the client elevate her legs when lying down
• D. Recommend the client take short walks throughout the day

Correct answer: A

Rationale: The correct answer is to advise the client to lie on her side. Lying on the side can prevent the compression of the vena cava, which can cause dizziness in pregnant women. Encouraging the client to drink more fluids (Choice B) may be beneficial for other conditions but is not the best response for dizziness when lying on her back. Suggesting the client elevate her legs when lying down (Choice C) is not directly related to the issue described by the client. Recommending the client take short walks throughout the day (Choice D) may be helpful for other pregnancy-related symptoms but is not the most appropriate action for dizziness when lying on her back.

3. The client with newly diagnosed peptic ulcer disease (PUD) is being taught about lifestyle modifications. Which instruction should be included?

• A. Increase the intake of spicy foods
• B. Avoid the use of nonsteroidal anti-inflammatory drugs (NSAIDs)
• C. Drink coffee in moderation
• D. Eat large meals at bedtime

Correct answer: B

Rationale: The correct instruction to include when teaching a client with newly diagnosed PUD about lifestyle modifications is to avoid the use of nonsteroidal anti-inflammatory drugs (NSAIDs). NSAIDs can exacerbate peptic ulcer disease by causing further irritation of the gastric mucosa. Increasing the intake of spicy foods (choice A) can aggravate the condition by irritating the stomach lining. Drinking coffee (choice C) can stimulate gastric acid secretion, which may worsen the symptoms of PUD. Eating large meals at bedtime (choice D) can also exacerbate PUD by increasing gastric acid production when the body is at rest, potentially leading to discomfort and symptoms.

4. A client with a severe peanut allergy accidentally ingested peanut-containing food and is experiencing anaphylaxis. What is the nurse's priority action?

• A. Administer an epinephrine injection
• B. Call for immediate medical help
• C. Monitor airway, breathing, and circulation
• D. All of the above

Correct answer: A

Rationale: The priority action for a client experiencing anaphylaxis due to a severe peanut allergy is to administer an epinephrine injection. Epinephrine is the first-line treatment for anaphylaxis as it can rapidly reverse the severe allergic reaction. While calling for immediate medical help is important, administering epinephrine takes precedence because it can be life-saving in this situation. Monitoring airway, breathing, and circulation is essential in managing anaphylaxis, but administering epinephrine is the priority action to halt the progression of the allergic reaction and stabilize the client's condition. Therefore, 'Administer an epinephrine injection' is the most critical initial intervention.

5. The practical nurse is preparing to administer a prescription for cefazolin (Kefzol) 600 mg IM every six hours. The available vial is labeled, 'Cefazolin (Kefzol) 1 gram,' and the instructions for reconstitution state, 'For IM use add 2 ml sterile water for injection. Total volume after reconstitution = 2.5 ml.' When reconstituted, how many milligrams are in each milliliter of solution?

• A. 400 mg/mL
• B. 500 mg/mL
• C. 450 mg/mL
• D. 350 mg/mL

Correct answer: A

Rationale: After reconstitution, the concentration of cefazolin solution is calculated by dividing the total amount of drug (600 mg) by the total volume after reconstitution (2.5 mL). This gives 600 mg / 2.5 mL = 240 mg/mL. However, the question asks for the concentration in each milliliter of solution after reconstitution, so we need to consider the final volume of 2.5 mL. Therefore, 240 mg/mL * 2.5 mL = 600 mg, which means each milliliter contains 240 mg of cefazolin. Therefore, after reconstitution, there are 400 mg of cefazolin in each milliliter of solution. Choices B, C, and D are incorrect as they do not accurately reflect the concentration after reconstitution.
