Nursing Elites

1. The healthcare provider attaches a pulse oximeter to a client's fingers and obtains an oxygen saturation reading of 91%. Which assessment finding most likely contributes to this reading?

• A. BP 142/88 mmHg
• B. 2+ edema of fingers and hands
• C. Radial pulse volume is +3
• D. Capillary refill time is 2 seconds

Correct answer: B

Rationale: Edema in the fingers and hands can impede the proper functioning of the pulse oximeter, leading to a falsely low oxygen saturation reading. Edema alters the transmission of light through the tissues, affecting the accuracy of the measurement. Therefore, the presence of edema in the fingers and hands is the most likely factor contributing to the low oxygen saturation reading of 91%.

2. When planning care for a client with an indwelling urinary catheter, which nursing diagnosis has the highest priority?

• A. Self-care deficit
• B. Functional incontinence
• C. Fluid volume deficit
• D. High risk for infection

Correct answer: D

Rationale: The highest priority nursing diagnosis when planning care for a client with an indwelling urinary catheter is 'High risk for infection.' Indwelling urinary catheters pose a significant risk of infection due to their direct contact with the urinary system. Preventing and managing infections is crucial in the care of these clients. Monitoring for signs of infection, following proper catheter care protocols, and maintaining aseptic technique during catheter maintenance are essential steps to prevent complications associated with catheter-related infections. Choices A, B, and C are not the highest priority because in this case, the immediate concern is the risk of infection associated with the presence of the urinary catheter. While self-care deficit, functional incontinence, and fluid volume deficit are important considerations in overall patient care, they are not as critical as preventing potentially serious infections related to the indwelling urinary catheter.

3. A client has an elevated AST 24 hours following chest pain and shortness of breath. This is suggestive of which of the following?

• A. Gallbladder disease
• B. Liver disease
• C. Myocardial infarction
• D. Skeletal muscle injury

Correct answer: C

Rationale: An elevated AST level following chest pain and shortness of breath is suggestive of myocardial infarction. AST is released from damaged heart muscle cells during a heart attack, indicating cardiac involvement. This enzyme is not specific to liver disease, gallbladder disease, or skeletal muscle injury in this clinical context.

4. When assessing a client with wrist restraints, the nurse observes that the fingers on the right hand are blue. What action should the nurse implement first?

• A. Loosen the right wrist restraint.
• B. Apply a pulse oximeter to the right hand.
• C. Compare hand color bilaterally.
• D. Palpate the right radial pulse.

Correct answer: A

Rationale: The priority nursing action is to restore circulation by loosening the restraint (A) because blue fingers (cyanosis) indicate decreased circulation. Comparing hand color bilaterally (C) and palpating the right radial pulse (D) are important assessments to gather more information, but they do not have the priority of addressing the decreased circulation by loosening the restraint. Applying a pulse oximeter (B) is not indicated in this scenario as it measures the saturation of hemoglobin with oxygen, which is not relevant when cyanosis is related to mechanical compression from the restraints.

5. After ensuring correct tube placement, what action should the nurse take next when administering medications through a nasogastric tube (NGT) connected to suction?

• A. Clamp the tube for 20 minutes.
• B. Flush the tube with water.
• C. Administer the medications as prescribed.
• D. Crush the tablets and dissolve in sterile water.

Correct answer: B

Rationale: After ensuring the correct placement of the NGT, the nurse should flush the tube with water to prevent any obstructions and ensure proper medication delivery. Flushing the tube is essential before, after, and in between each medication administration. Clamping the tube for 20 minutes should be done after all medications are administered to prevent clogging. Administering medications as prescribed and preparing medications by crushing tablets and dissolving them in sterile water should only be done after the tube has been appropriately flushed to maintain its patency and effectiveness.
