1. Which action should the nurse implement when using the confrontation technique during a vision exam?
- A. Use an ophthalmoscope to observe the client's pupil constriction when a strong light is shone on it.
- B. Stand behind the client and direct the client to report when an object enters the peripheral field of vision.
- C. Display a series of four cards with printing of varying sizes to the client and ask which card the client sees most clearly.
- D. Sit facing the client, look directly at the client's face, and move an object inward from the periphery.
Correct answer: D
Rationale: During a vision exam, the confrontation technique is used to assess peripheral vision. By sitting facing the client and moving an object inward from the periphery while looking directly at the client's face, the nurse allows the client to indicate when the object enters the visual field. This method helps in determining the extent of the client's peripheral vision accurately. Choices A, B, and C are incorrect as they do not describe the appropriate method for using the confrontation technique during a vision exam. Choice A involves using an ophthalmoscope to observe pupil constriction, choice B involves testing the peripheral field of vision without the confrontation technique, and choice C describes the Snellen eye chart test for visual acuity, which is not related to the confrontation technique.
2. 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%.
3. The client is being taught about the use of syringes and needles for home administration of medications. Which action by the client indicates an understanding of standard precautions?
- A. Remove needle before discarding used syringes
- B. Wear gloves to dispose of the needle and syringe
- C. Don a face mask before administering the medication
- D. Wash hands before handling the needle and syringe
Correct answer: D
Rationale: Washing hands before handling needles and syringes is a crucial aspect of standard precautions to prevent infections. This practice helps reduce the risk of transferring microorganisms from the hands to the syringes and needles, thus promoting safety during medication administration.
4. The client has received a new diagnosis of heart failure, and the nurse is providing dietary management education. Which instruction should the nurse include?
- A. Increase intake of foods high in potassium.
- B. Avoid foods high in sodium.
- C. Limit fluid intake to 1.5 liters per day.
- D. Increase intake of foods high in vitamin K.
Correct answer: B
Rationale: Avoiding foods high in sodium (choice B) is essential for clients with heart failure to prevent fluid retention and decrease the strain on the heart. High sodium intake can lead to fluid buildup, exacerbating heart failure symptoms. Increasing potassium intake (choice A) can be harmful in heart failure if not monitored closely as it can affect heart rhythm. Limiting fluid intake (choice C) may be necessary in some cases, but the specific amount should be individualized based on the client's condition. Increasing vitamin K intake (choice D) is not a primary concern in heart failure management and is more relevant for clients on anticoagulants to manage blood clotting.
5. The healthcare professional is administering an intermittent infusion of an antibiotic to a client with an antecubital saline lock. After opening the roller clamp on the IV tubing, the alarm on the infusion pump indicates an obstruction. What action should be taken first?
- A. Check for a blood return.
- B. Reposition the client's arm.
- C. Remove the IV site dressing.
- D. Flush the lock with saline.
Correct answer: B
Rationale: Repositioning the client's arm is the initial action to take when encountering an obstruction with an antecubital saline lock. Repositioning may correct any bending at the elbow that could be causing the obstruction, allowing for smoother infusion flow. Checking for a blood return, removing the IV site dressing, or flushing the lock with saline would be subsequent actions once the obstruction is addressed. Checking for a blood return is done to confirm proper placement, removing the IV site dressing is necessary for site assessment, and flushing the lock with saline helps maintain patency but should not be the first action when an obstruction is detected.
