Nursing Elites

1. A client has an NG tube that needs to be irrigated every 8 hours. Which solution should the nurse use to maintain fluid and electrolyte balance?

• A. Tap water
• B. Sterile water
• C. 0.9% sodium chloride
• D. 0.45% sodium chloride

Correct answer: C

Rationale: The correct solution to maintain fluid and electrolyte balance during NG tube irrigation is 0.9% sodium chloride. This solution is isotonic and helps prevent electrolyte imbalances. Using tap water or sterile water can lead to electrolyte disturbances due to their hypotonic nature, while 0.45% sodium chloride is hypotonic and may cause further imbalances in the client's electrolyte levels.

2. Which intervention is most important for a client with rheumatoid arthritis?

• A. Massage inflamed joints with creams and oils
• B. Provide support to flexed joints with pillows and pads
• C. Position the client on their abdomen several times a day
• D. Assist with heat application and range of motion exercises

Correct answer: D

Rationale: The most important intervention for a client with rheumatoid arthritis is to assist with heat application and range of motion exercises. Heat application helps reduce stiffness and improve joint flexibility, while range of motion exercises help maintain mobility and prevent contractures. Massaging inflamed joints with creams and oils may provide temporary relief but does not address the root cause of stiffness and limited mobility in rheumatoid arthritis. Providing support to flexed joints with pillows and pads can be helpful for comfort but does not actively promote mobility. Positioning the client on their abdomen several times a day is not a standard intervention for managing rheumatoid arthritis.

3. A nurse is providing discharge instructions to a client with home oxygen therapy. What safety measure should the nurse emphasize?

• A. Allow smoking in designated outdoor areas
• B. Keep oxygen tanks upright and away from heat sources
• C. Store oxygen tanks in a closet when not in use
• D. Keep oxygen equipment at least 10 feet away from open flames

Correct answer: B

Rationale: The correct safety measure that the nurse should emphasize is to keep oxygen tanks upright and away from heat sources. This is crucial to prevent the risk of fire or explosion. Choice A is incorrect as smoking near oxygen can lead to a fire hazard. Choice C is also incorrect as storing oxygen tanks in enclosed spaces can be dangerous. Choice D, although related to safety, does not address the immediate risk of keeping oxygen tanks away from heat sources.

4. A client who is taking furosemide is being taught by a nurse about dietary modifications. Which of the following foods should the nurse recommend to the client?

• A. Bananas
• B. Cabbage
• C. Potatoes
• D. Carrots

Correct answer: A

Rationale: The correct answer is A, Bananas. Bananas are high in potassium, which is essential for clients taking furosemide to prevent hypokalemia. Furosemide is a diuretic that can cause potassium loss through increased urine output. Therefore, recommending foods rich in potassium, such as bananas, can help maintain potassium levels within the normal range. Choices B, C, and D are not the best recommendations in this case as they are not particularly high in potassium.

5. What is the proper technique for measuring a patient's blood pressure?

• A. Place the cuff at heart level and listen for Korotkoff sounds
• B. Ensure the patient is in a seated position and inflate the cuff to 180 mmHg
• C. Use a manual sphygmomanometer and measure blood pressure on both arms
• D. Monitor pulse rate and apply pressure to the brachial artery

Correct answer: A

Rationale: The correct technique for measuring blood pressure involves placing the cuff at heart level to ensure accurate readings. Listening for Korotkoff sounds helps determine the systolic and diastolic pressures. Choice B is incorrect as inflating the cuff to 180 mmHg is excessive and can lead to inaccurate readings. Choice C is incorrect as it is unnecessary to measure blood pressure on both arms unless there is a specific medical reason to do so. Choice D is incorrect as monitoring pulse rate and applying pressure to the brachial artery are not part of the standard blood pressure measurement technique.
