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?

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. When taking a client's blood pressure, the healthcare professional is unable to distinguish the point at which the first sound was heard. What is the best action for the healthcare professional to take?

Correct answer: C

Rationale: The correct action when unable to distinguish the point of the first sound during blood pressure measurement is to deflate the cuff to zero and wait 30 to 60 seconds before reattempting the reading. This allows blood flow to return to the extremity, ensuring a more accurate reading the second time. It is important to ensure that the cuff is fully deflated and the appropriate wait time is given to obtain an accurate blood pressure measurement.

3. At a motor vehicle collision site, a nurse applies pressure to a groin wound that is bleeding profusely until emergency personnel arrive. Subsequently, the client undergoes leg amputation and sues the nurse for malpractice. What is the most likely outcome of this lawsuit?

Correct answer: C

Rationale: The Good Samaritan Act shields healthcare professionals who act in good faith and offer reasonable care from malpractice claims, irrespective of the client's outcome. In this scenario, the nurse stopping to render aid at the accident scene and applying pressure to the bleeding groin wound would likely be covered by the Good Samaritan Act, protecting the nurse from legal repercussions related to the subsequent leg amputation.

4. When making the bed of a client who needs a bed cradle, which action should the nurse include?

Correct answer: D

Rationale: A bed cradle is used to keep the top bedclothes off the client, so the nurse should drape the top sheet and covers loosely over the cradle. This helps in maintaining the proper positioning and function of the bed cradle to ensure the client's comfort and safety during bed making.

5. A male client is on contact precautions due to an infected draining wound and is being discharged home. The client lives at home with his wife and their adolescent daughter. What discharge instruction should the nurse include for the client?

Correct answer: C

Rationale: When a client is on contact precautions due to an infected draining wound, it is important to prevent contact with wound secretions. Therefore, disposing of soiled dressings in securely closed plastic bags helps contain and prevent the spread of infectious material, reducing the risk of transmission to others in the household.
