Nursing Elites

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. A client with a history of myocardial infarction (MI) is admitted with chest pain. Which laboratory test should the nurse expect to be ordered to determine if the client is experiencing another MI?

• A. Troponin
• B. Myoglobin
• C. CK-MB
• D. C-reactive protein

Correct answer: A

Rationale: Troponin is the most specific and sensitive laboratory test for detecting myocardial infarction (MI). It is released when there is damage to the heart muscle, making it a valuable marker for diagnosing another MI. Myoglobin and CK-MB can also be elevated in MI, but troponin is preferred due to its higher specificity. C-reactive protein is a marker of inflammation and not specific to MI.

3. The nurse is instructing a client with high cholesterol about diet and life style modification. What comment from the client indicates that the teaching has been effective?

• A. If I exercise at least two times weekly for one hour, I will lower my cholesterol.
• B. I need to avoid eating proteins, including red meat.
• C. I will limit my intake of beef to 4 ounces per week.
• D. My blood level of low density lipoproteins needs to increase.

Correct answer: C

Rationale: Limiting saturated fat from animal food sources to no more than 4 ounces per week is an important diet modification for lowering cholesterol. To be effective in reducing cholesterol, the client should exercise 30 minutes per day, or at least 4 to 6 times per week. Red meat and all proteins do not need to be eliminated to lower cholesterol, but should be restricted to lean cuts of red meat and smaller portions. The low density lipoproteins need to decrease rather than increase.

4. You are assigned to teach a student how to suction an adult patient with a tracheostomy. Which of the following actions by the student would be incorrect?

• A. Pre-oxygenating the patient with a Resuscibag at 100% O2 several times before suctioning.
• B. Maintaining wall suction pressure at 110-150 mmHg.
• C. Not suctioning for greater than 10-15 seconds at a time.
• D. Applying gentle intermittent pressure and rotating the catheter during the insertion phase of suctioning.

Correct answer: D

Rationale: The incorrect action by the student is applying gentle intermittent pressure and rotating the catheter during the insertion phase of suctioning. This technique can cause trauma to the tracheal walls, increasing the risk of injury to the patient. It is essential to perform suctioning gently and without rotation to prevent complications in patients with a tracheostomy. Pre-oxygenating the patient, maintaining appropriate suction pressure, and limiting suctioning time are all correct actions when suctioning a patient with a tracheostomy.

5. 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.
