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. A client is admitted with a diagnosis of heart failure. Which dietary instruction should the nurse provide?

• A. Increase fluid intake to 3 liters per day.
• B. Limit sodium intake to 2 grams per day.
• C. Avoid foods high in potassium.
• D. Increase protein intake to promote healing.

Correct answer: B

Rationale: Limiting sodium intake to 2 grams per day (B) is a crucial dietary instruction for clients with heart failure. It helps manage fluid retention and reduces the workload on the heart. Excessive sodium can lead to fluid retention, worsening heart failure symptoms. Increasing fluid intake (A) can further exacerbate fluid overload in heart failure patients. Avoiding foods high in potassium (C) is not necessary unless the client has hyperkalemia; in heart failure, potassium restriction is not a primary dietary concern. Increasing protein intake (D) is not the priority for heart failure management; focusing on sodium restriction is more beneficial.

3. What is the most important instruction for the nurse to provide a client with a new colostomy regarding stoma care?

• A. Cleanse the stoma with hydrogen peroxide and water.
• B. Apply a moisture barrier cream to the peristomal skin.
• C. Measure the stoma using a stoma guide.
• D. Use a dry gauze pad to clean the stoma.

Correct answer: C

Rationale: Measuring the stoma using a stoma guide (C) is crucial as it ensures that the appliance fits properly, which is essential for preventing skin irritation and leakage. Proper measurement helps in selecting the right size of the appliance, promoting comfort and optimal stoma care. In contrast, cleansing with hydrogen peroxide (A), applying a moisture barrier cream (B), and using a dry gauze pad (D) are important but not as critical as ensuring the correct fit of the stoma appliance.

4. During the insertion of a nasogastric tube (NGT), the client begins to cough and gag. What action should the healthcare professional take?

• A. Stop advancing the tube and allow the client to rest
• B. Remove the tube and try again after a few minutes
• C. Continue inserting the tube while the client sips water
• D. Withdraw the tube slightly and pause before continuing

Correct answer: D

Rationale: When a client begins to cough and gag during the insertion of a nasogastric tube, withdrawing the tube slightly and pausing is the appropriate action. This technique helps prevent further irritation, gives the client a moment to recover, and allows for a smoother continuation of the insertion process. Choice A is incorrect because allowing the client to rest without adjusting the tube position might not address the issue. Choice B is incorrect as removing the tube without addressing the cause of coughing and gagging may lead to repeated discomfort. Choice C is incorrect as continuing to insert the tube while the client is experiencing difficulties can increase discomfort and potential complications.

5. Which assessment data would provide the most accurate determination of proper placement of a nasogastric tube?

• A. Aspirating gastric contents to assure a pH value of 4 or less.
• B. Hearing air pass in the stomach after injecting air into the tubing.
• C. Examining a chest x-ray obtained after the tubing was inserted.
• D. Checking the remaining length of tubing to ensure that the correct length was inserted.

Correct answer: C

Rationale: The most accurate method to confirm the proper placement of a nasogastric tube is by examining a chest x-ray obtained after the tubing was inserted. This visual assessment allows healthcare providers to directly visualize the position of the tube in relation to anatomical landmarks, ensuring it is correctly placed in the stomach. Aspirating gastric contents or hearing air pass may provide some information but are not as definitive as a chest x-ray for confirming placement. Checking the remaining length of tubing is not a reliable method for determining proper placement as it does not indicate where the tip of the tube lies within the body.
