A nurse is reviewing a client’s orders and notes the following: Vital signs every 4 hours, regular diet, Cefazolin 1g IV every 8 hours for 5 days, Metformin 1,000 mg PO every 12 hours, and point of care blood glucose check every 4 hours. Which action should the nurse take?
Place the client on contact precautions.
Start a high-fiber diet.
Administer an oral steroid.
Make the client NPO.
The Correct Answer is D
Choice A rationale
Placing the client on contact precautions is not indicated based on the provided orders. Contact precautions are typically used for infections that are spread by direct or indirect contact, such as MRSA or C. difficile. The orders do not suggest the presence of such an infection.
Choice B rationale
Starting a high-fiber diet is not indicated. The client is already on a regular diet, and there is no mention of conditions that would necessitate a high-fiber diet, such as constipation or diverticulosis.
Choice C rationale
Administering an oral steroid is not indicated. The orders include Cefazolin, an antibiotic, and Metformin, an antidiabetic medication. There is no indication for an oral steroid, which is typically used for inflammatory conditions or autoimmune diseases.
Choice D rationale
Making the client NPO (nothing by mouth) is the correct action. This is likely due to the need for accurate blood glucose monitoring and the administration of IV antibiotics. Being NPO ensures that the client does not eat or drink anything that could interfere with these treatments.

Correct Answer is C
Explanation
Choice A rationale
Inspecting crutches to ensure rubber tips are intact is important for safety, but it does not indicate an understanding of proper crutch walking technique. Proper crutch walking involves more than just equipment inspection.
Choice B rationale
Practicing bicep and triceps isometric exercises can help strengthen the muscles needed for crutch walking, but it does not directly demonstrate an understanding of the correct crutch gait. The focus should be on the actual technique of using the crutches.
Choice C rationale
Bearing body weight on the palms of hands during the crutch gait is the correct behavior that indicates an understanding of proper crutch walking. This technique helps distribute weight appropriately and prevents strain on the underarms, which can cause nerve damage and discomfort.
Choice D rationale
Progressing to foot touchdown and weight bearing of the affected leg is not appropriate for a three-point gait, which is used when the client should not bear any weight on the affected leg. This choice indicates a misunderstanding of the correct crutch walking technique for this specific gait.
Correct Answer is A
Explanation
Choice A rationale
Edema in the fingers and hands can affect the accuracy of a pulse oximeter reading. The swelling can interfere with the probe’s ability to detect the blood flow properly, leading to a falsely low oxygen saturation reading.
Choice B rationale
A capillary refill time of 2 seconds is considered normal and does not typically affect the accuracy of a pulse oximeter reading.
Choice C rationale
Blood pressure of 142/88 mm Hg, while elevated, does not directly impact the accuracy of a pulse oximeter reading.
Choice D rationale
A radial pulse volume of 3+ indicates a strong pulse, which should not interfere with the accuracy of a pulse oximeter reading.
