1. In what sequence should the nurse prepare the dose of insulin for a client whose finger stick glucose is 210 mg/dl and is receiving a sliding scale dose of short-acting insulin before breakfast?
- A. Clean the vial's rubber stopper with an alcohol swab, withdraw the correct dose of insulin, and then inject air equal to the insulin dose into the vial.
- B. Inject air equal to the insulin dose into the vial, withdraw the correct dose of insulin, and then clean the vial's rubber stopper with an alcohol swab.
- C. Withdraw the correct dose of insulin, inject air equal to the insulin dose into the vial, and then clean the vial's rubber stopper with an alcohol swab.
- D. Clean the vial's rubber stopper with an alcohol swab, inject air equal to the insulin dose into the vial, and then withdraw the correct dose of insulin.
Correct answer: A
Rationale: The correct sequence for preparing a dose of insulin involves ensuring proper aseptic technique. First, clean the vial's rubber stopper with an alcohol swab to prevent contamination. Second, withdraw the correct dose of insulin to be administered. Lastly, inject air equal to the insulin dose into the vial to maintain proper pressure for withdrawing the medication. This sequence ensures the medication is prepared safely and accurately. Choice A is correct as it follows this sequence. Choices B, C, and D present incorrect sequences that may compromise patient safety by not following the correct aseptic technique. Choice B injects air into the vial before withdrawing insulin, which is incorrect. Choice C reverses the order of withdrawing insulin and injecting air. Choice D withdraws the insulin before injecting air, which can affect the pressure inside the vial and lead to inaccurate dosing.
2. A client with multiple sclerosis is experiencing scotomas (blind spots), which are limiting peripheral vision. What intervention should the nurse include in this client's plan of care?
- A. Encourage the use of corrective lenses during the day
- B. Practice visual exercises that focus on a still object
- C. Alternate an eye patch from eye every 2 hours
- D. Teach techniques for scanning the environment
Correct answer: D
Rationale: The correct intervention for a client with multiple sclerosis experiencing scotomas and limited peripheral vision is to teach techniques for scanning the environment. This intervention helps the client compensate for vision loss by learning how to scan and explore their surroundings effectively. Encouraging the use of corrective lenses may not address the issue of scotomas, and visual exercises focusing on a still object may not enhance peripheral vision. Alternating an eye patch every 2 hours is not typically indicated for scotomas in multiple sclerosis, making it an incorrect choice.
3. What intervention should the nurse implement during the administration of a vesicant chemotherapeutic agent via an IV site in the client's arm?
- A. Assess IV site frequently for signs of extravasation
- B. Monitor capillary refill distal to the infusion site
- C. Apply a topical anesthetic at the infusion site for burning
- D. Explain that temporary burning at the IV site may occur
Correct answer: A
Rationale: The correct intervention the nurse should implement during the administration of a vesicant chemotherapeutic agent via an IV site in the client's arm is to assess the IV site frequently for signs of extravasation. Vesicants are agents that can cause tissue damage if they leak into the surrounding tissues. Monitoring for signs of extravasation such as swelling, pain, or redness is crucial to prevent tissue damage and ensure prompt intervention if extravasation occurs. Choices B, C, and D are incorrect because monitoring capillary refill, applying a topical anesthetic for burning, and explaining temporary burning do not directly address the risk of extravasation associated with vesicant chemotherapeutic agents.
4. A male client with schizophrenia is jerking his neck and smacking his lips. Which finding indicates to the nurse that he is experiencing an irreversible side effect of antipsychotic agents?
- A. Cramping muscular pain
- B. Worming movements of the tongue
- C. Decreased tendon reflexes
- D. Dry oral mucous membranes
Correct answer: B
Rationale: The correct answer is B: Worming movements of the tongue. Worming movements of the tongue, known as tardive dyskinesia, are an irreversible side effect of antipsychotic medications. Tardive dyskinesia is characterized by involuntary, repetitive movements of the tongue, lips, face, trunk, and extremities. Cramping muscular pain (Choice A) is more indicative of dystonia, an extrapyramidal side effect that can be treated effectively with antiparkinsonian medications. Decreased tendon reflexes (Choice C) are not typically associated with irreversible side effects of antipsychotic agents. Dry oral mucous membranes (Choice D) are not specific to irreversible side effects of antipsychotic medications.
5. Prior to surgery, written consent must be obtained. What is the nurse’s legal responsibility with regard to obtaining written consent?
- A. Validate the client's understanding of the surgical procedure to be conducted
- B. Explain the surgical procedure to the client and ensure the client comprehends before signing the consent form
- C. Ensure the client, not a family member, signs the surgical consent form
- D. Confirm that the surgical consent form is signed and included in the client's record
Correct answer: A
Rationale: The nurse's legal responsibility in obtaining written consent is to validate the client's understanding of the surgical procedure to be conducted. This process ensures that the client has been comprehensively informed about the procedure, including its risks, benefits, and alternatives. Choice B is incorrect because it does not emphasize the validation of client understanding, which is crucial for informed consent. Choice C is incorrect as the client, not a family member, should provide consent unless specific circumstances dictate otherwise. Choice D is incorrect because although ensuring the consent form is signed and filed is important, it does not address the primary responsibility of confirming the client's comprehension and ensuring informed consent.
