A nurse is reviewing informed consent with a client who is scheduled for a cardiac catheterization. Which of the following is the responsibility of the nurse?
- A. Explaining the procedure's risks
- B. Obtaining the client's signature
- C. Verifying the client's understanding of the procedure being performed
- D. Scheduling the procedure
Correct Answer: C
Rationale: The nurse's role in informed consent is to ensure the client comprehends the procedure, supporting autonomy and legal standards. Verifying the client's understanding of the cardiac catheterization its purpose, process, and implications confirms they can articulate it, ensuring consent is truly informed, not just signed. Explaining risks is the provider's duty, as they perform the procedure and bear legal responsibility for disclosure. Obtaining the signature is procedural but secondary to comprehension, often a clerical task. Scheduling is logistical, unrelated to consent. Verification bridges provider explanation and client decision, empowering the client and protecting the healthcare team by validating that consent reflects genuine understanding, not coercion or confusion.
The clinic nurse has just accessed a client's chart on the computer. The resident comes over and asks her to stay logged on because he needs to add a note to that client's chart. She should say:
- A. No problem. Just log me off when you're done.'
- B. I'll put the note in for you. What do you want to say?'
- C. Just make sure that you sign your note because it's under my log in ID.'
- D. I'm sorry, but you will have to enter the information using your own log in ID.'
Correct Answer: D
Rationale: Patient privacy and data security are paramount in healthcare, governed by laws like HIPAA. Allowing the resident to use the nurse's login violates these principles, as each provider must use their own credentials to access and modify patient records. This ensures accountability every action is traceable to the individual who performed it and protects the nurse from liability for entries she didn't make. Offering to log off after the resident's use or adding the note herself compromises this accountability, potentially leading to errors or legal issues if the resident's input is inaccurate. Asking the resident to sign the note under her ID still ties her login to his actions, which is insufficient. Requiring the resident to use his own login upholds professional standards, safeguards patient information, and maintains clear responsibility for chart entries.
Client's potassium is $7.0 \mathrm{mEq} / \mathrm{dL}$. Which prescription should the nurse administer first?
- A. Calcium gluconate IV
- B. Sodium polystyrene enema
- C. Spironolactone oral
- D. Dextrose 10\% IV
Correct Answer: A
Rationale: With potassium at 7.0 mEq/dL, calcium gluconate IV goes first, not polystyrene, spironolactone, or dextrose. Hyperkalemia risks arrhythmias calcium stabilizes cardiac membranes fast, buying time. Polystyrene lowers potassium slowly, spironolactone's diuretic, and dextrose needs insulin. Leadership acts here imagine peaked T-waves; calcium prevents arrest, ensuring safety. This reflects nursing's emergency prioritization, aligning with cardiac stability effectively.
A client with recent stroke can understand the language but answers with incorrect words. Which communication problem is presenting?
- A. Aphasia
- B. Apraxia
- C. Dysarthria
- D. Dysphagia
Correct Answer: A
Rationale: Post-stroke, understanding language but using wrong words is aphasia, not apraxia, dysarthria, or dysphagia. Aphasia disrupts expression e.g., saying cat' for dog' while apraxia affects motor planning, dysarthria slurs speech, and dysphagia impairs swallowing. Leadership recognizes this imagine a frustrated patient; identifying aphasia guides therapy, enhancing recovery. This reflects nursing's role in neurological assessment, ensuring accurate communication support effectively.
A nurse is ambulating a client who has an IV with an infusion pump. After the nurse returns the client to his room and plugs in the infusion pump, the client reports a slight tingling in his hand. Which of the following actions should the nurse take?
- A. Turn off the pump
- B. Increase the infusion rate
- C. Tape the cord
- D. Notify maintenance only
Correct Answer: A
Rationale: Tingling in the hand after plugging in an IV pump suggests electrical malfunction possibly a short circuit or grounding issue posing shock or fire risks. Turning off the pump immediately halts potential harm, prioritizing client and staff safety, allowing assessment (e.g., cord damage) and tagging for repair. Increasing the rate ignores the symptom, worsening exposure, while taping the cord assumes a fix without evidence, delaying resolution. Notifying maintenance alone prolongs risk until they arrive. Shutting off aligns with safety-first principles, mitigating electrical hazards swiftly, critical in a clinical setting where equipment failure can escalate, ensuring protection until a full check confirms functionality.
