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. A male client with unstable angina needs a cardiac catheterization. The healthcare provider explains the risks and benefits of the procedure and then leaves to set up for the procedure. When the nurse presents the consent form for signature, the client hesitates and asks how the wires will keep his heart going. Which action should the nurse take?

• A. Answer the client’s specific questions with a short, understandable explanation
• B. Postpone the procedure until the client understands the risks and benefits
• C. Call the client’s next of kin and ask them to provide verbal consent
• D. Page the healthcare provider to return and provide additional explanation

Correct answer: D

Rationale: The nurse should ask the healthcare provider to return and provide further explanation to the client. The healthcare provider is the one who can address the risks and benefits of the procedure in detail, ensuring the client receives accurate information before providing consent.

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. A client is to receive 10 mEq of KCl diluted in 250 ml of normal saline over 4 hours. At what rate should the nurse set the client's intravenous infusion pump?

• A. 13 ml/hour.
• B. 63 ml/hour.
• C. 80 ml/hour.
• D. 125 ml/hour.

Correct answer: B

Rationale: The correct calculation involves dividing the total volume by the total time. In this case, 250 ml/4 hours = 63 ml/hour. The dose of KCl is not used in the calculation as the focus is on the rate of infusion over the specified time period. Choice A (13 ml/hour) is incorrect as it does not result from the correct calculation. Choice C (80 ml/hour) and Choice D (125 ml/hour) are also incorrect calculations and do not match the correct rate of infusion required.

5. To avoid nerve injury, what location should the nurse select to administer a 3 mL IM injection?

• A. Ventrogluteal
• B. Outer upper quadrant of the buttock
• C. Two inches below the acromion process
• D. Vastus lateralis

Correct answer: A

Rationale: The ventrogluteal site is the preferred location for administering large volume IM injections to avoid nerve injury. This site is situated away from major nerves and blood vessels, reducing the risk of complications associated with injecting into other areas. The ventrogluteal site allows for deep muscle penetration and is recommended for injections over 2 mL in volume to ensure proper dispersion and absorption of the medication. Choices B, C, and D are incorrect because the outer upper quadrant of the buttock is not the recommended site for large volume injections, two inches below the acromion process is a location for a deltoid injection, and the vastus lateralis is typically used for smaller volume injections.
