Nursing Elites

1. The client with chronic obstructive pulmonary disease (COPD) is being taught pursed-lip breathing by the nurse. What is the purpose of this technique?

• A. To promote oxygenation by removing secretions.
• B. To reduce the amount of air trapped in the lungs.
• C. To increase the amount of carbon dioxide exhaled.
• D. To slow the respiratory rate and improve air exchange.

Correct answer: C

Rationale: Pursed-lip breathing is used to increase the amount of carbon dioxide exhaled (C) in clients with chronic obstructive pulmonary disease (COPD). By doing so, it helps prevent air trapping and enhances gas exchange, ultimately improving respiratory efficiency. While removing secretions (A) and reducing air trapping (B) can be associated benefits to some extent, the primary goal of pursed-lip breathing is to optimize carbon dioxide elimination and enhance breathing mechanics. Slowing the respiratory rate (D) is not the primary purpose of pursed-lip breathing.

2. Which client care task requires the nurse to wear barrier gloves as mandated by the Standard Precautions protocol?

• A. Removing the empty food tray from a client with a urinary catheter.
• B. Washing and combing the hair of a client with a fractured leg in traction.
• C. Administering oral medications to a cooperative client with a wound infection.
• D. Emptying the urinary catheter drainage bag for a client with Alzheimer's disease.

Correct answer: D

Rationale: The correct answer is D because emptying a urinary catheter drainage bag exposes the nurse to body fluids, necessitating the use of barrier gloves as per Standard Precautions to prevent potential infection transmission.

3. During a client assessment, the healthcare provider is evaluating cranial nerve function. Which assessment finding suggests that cranial nerve II is intact?

• A. The client can hear a whisper from 1 to 2 feet away.
• B. The client can identify an object by touch.
• C. The client can shrug the shoulders against resistance.
• D. The client can read a Snellen chart from 20 feet away.

Correct answer: D

Rationale: The ability to read a Snellen chart from 20 feet away indicates intact cranial nerve II (optic nerve), responsible for vision. Hearing a whisper (A) is associated with cranial nerve VIII (vestibulocochlear nerve), identifying an object by touch (B) is related to cranial nerves V (trigeminal nerve) and VII (facial nerve), and shoulder shrugging against resistance (C) is a test for cranial nerve XI (accessory nerve). Thus, the correct answer is D as it specifically tests the function of cranial nerve II.

4. A client with a diagnosis of hyperkalemia is receiving sodium polystyrene sulfonate (Kayexalate). Which laboratory value should the nurse monitor to evaluate the effectiveness of this medication?

• A. Serum sodium level.
• B. Serum potassium level.
• C. Serum calcium level.
• D. Serum glucose level.

Correct answer: B

Rationale: The correct answer is B: Serum potassium level. Sodium polystyrene sulfonate (Kayexalate) is used to treat hyperkalemia by exchanging sodium ions for potassium ions in the intestines, leading to potassium removal from the body. Monitoring the serum potassium level allows the nurse to assess the effectiveness of this medication in lowering the elevated potassium levels. Serum sodium (A), calcium (C), and glucose (D) levels are not directly impacted by the action of sodium polystyrene sulfonate.

5. After insertion of the indwelling catheter, how should the nurse position the drainage container?

• A. With the drainage tubing taut to maintain maximum suction on the urinary bladder.
• B. Lower than the bladder to maintain a constant downward flow of urine from the bladder.
• C. At the head of the bed for easy and accurate measurement of urine.
• D. Beside the patient in their bed to avoid embarrassment.

Correct answer: B

Rationale: The correct position for the drainage container after inserting an indwelling catheter is to have it placed lower than the bladder. This positioning helps maintain a constant downward flow of urine from the bladder, preventing backflow and ensuring proper drainage. Choice A is incorrect because having the drainage tubing taut does not promote proper urine flow and may cause kinking. Choice C is incorrect as placing the container at the head of the bed does not affect drainage and is not necessary for accurate measurement. Choice D is incorrect as the positioning of the drainage container should prioritize proper drainage and care over potential embarrassment.
