Nursing Elites

1. The nurse is reviewing a client's electrocardiogram and determines the PR interval (PRI) is prolonged. What does this finding indicate?

• A. Initiation of the impulses from a location outside the SA node
• B. Inability of the SA node to initiate an impulse at the normal rate
• C. Increased conduction time from the SA node to the AV junction
• D. Interference with the conduction through one or both ventricles

Correct answer: C

Rationale: When the PR interval is prolonged, it signifies an increased conduction time from the SA node through the AV junction. This finding is characteristic of a first-degree heart block where there is a delay in the electrical conduction at the level of the AV node. Choices A, B, and D are incorrect as they do not accurately reflect the significance of a prolonged PR interval.

2. A 75-year-old female client is admitted to the orthopedic unit following an open reduction and internal fixation of a hip fracture. On the second postoperative day, the client becomes confused and repeatedly asks the nurse where she is. What information is most important for the nurse to obtain?

• A. History of alcohol use
• B. Current medication list
• C. Baseline cognitive status
• D. Family history of dementia

Correct answer: A

Rationale: The correct answer is A: History of alcohol use. In this scenario, obtaining the history of alcohol use is crucial as it could indicate withdrawal, which might explain the client's confusion. Alcohol withdrawal can lead to symptoms such as confusion, agitation, and disorientation. While knowing the current medication list (choice B) is important for overall patient care, in this case, alcohol withdrawal is a more likely cause of the confusion. Baseline cognitive status (choice C) is valuable for comparison but may not directly explain the sudden confusion. Family history of dementia (choice D) is less relevant in this acute situation compared to the potential immediate impact of alcohol withdrawal.

3. A client with a history of hypertension is prescribed a beta-blocker. Which client statement indicates that further teaching is needed?

• A. ‘I will take my medication in the morning before breakfast.’
• B. ‘I should avoid eating foods high in potassium.’
• C. ‘I should change positions slowly to avoid dizziness.’
• D. ‘I should avoid abrupt discontinuation of the medication.’

Correct answer: B

Rationale: The correct answer is B: ‘I should avoid eating foods high in potassium.’ This statement indicates a misunderstanding as beta-blockers do not typically affect potassium levels. The other choices (A, C, and D) are all appropriate statements for a client prescribed a beta-blocker. Choice A shows understanding of the timing of medication administration, choice C addresses orthostatic hypotension concerns, and choice D highlights the importance of not abruptly stopping the medication to prevent adverse effects.

4. The nurse is preparing to administer an intramuscular injection to a client with muscle wasting in the gluteal region. What is the most appropriate site for the injection?

• A. Dorsogluteal site
• B. Ventrogluteal site
• C. Deltoid site
• D. Vastus lateralis site

Correct answer: D

Rationale: The vastus lateralis site is the most appropriate for an IM injection in a client with muscle wasting in the gluteal region. Administering the injection in the vastus lateralis ensures effective medication delivery due to muscle wasting in the gluteal region, preventing potential complications associated with the dorsogluteal or ventrogluteal sites, which may not be suitable in this specific client case. The deltoid site is mainly used for smaller volumes of medication and may not be ideal for this scenario.

5. A male client with impaired renal function who takes ibuprofen daily for chronic arthritis is admitted with gastrointestinal (GI) bleeding. After administering IV fluids and a blood transfusion, his blood pressure is 100/70, and his renal output is 20 ml/hour. Which intervention should the nurse include in care?

• A. Maintain the client NPO during the diuresis phase.
• B. Evaluate daily serial renal laboratory studies for progressive elevations.
• C. Observe the urine character for sedimentation and cloudy appearance.
• D. Monitor for onset of polyuria greater than 150ml/hour.

Correct answer: B

Rationale: Evaluating daily renal laboratory studies is crucial in this scenario. The client has impaired renal function, recent GI bleeding, and is at risk for further kidney damage due to ibuprofen use. Monitoring renal labs helps assess kidney function and detect any progressive elevations, guiding further interventions. Option A is not directly related to renal function monitoring. Option C focuses more on urine appearance than renal function assessment. Option D mentions polyuria, which is excessive urine output, but the question describes a client with reduced renal output.
