1. By rolling contaminated gloves inside-out, the healthcare professional is affecting which step in the chain of infection?

• A. Mode of transmission
• B. Portal of entry
• C. Reservoir
• D. Portal of exit

Correct answer: A

Rationale: When contaminated gloves are rolled inside-out, they are serving as a mode of transmission by carrying pathogens from the reservoir's portal of exit to a new portal of entry. This action increases the risk of transmitting infections from one person to another, emphasizing the importance of proper glove removal techniques to prevent the spread of pathogens. Choices B, C, and D are incorrect in this context. Portal of entry refers to the route through which a pathogen enters a susceptible host, reservoir is the habitat where the pathogen lives, grows, and multiplies, and portal of exit is the path through which a pathogen leaves its host.

2. A client is to receive cimetidine (Tagamet) 300 mg q6h IVP. The preparation arrives from the pharmacy diluted in 50 ml of 0.9% NaCl. The nurse plans to administer the IVPB dose over 20 minutes. For how many ml/hr should the infusion pump be set to deliver the secondary infusion?

• A. 75 ml/hr
• B. 150 ml/hr
• C. 225 ml/hr
• D. 300 ml/hr

Correct answer: B

Rationale: To calculate the infusion rate, set up a ratio proportion problem: 50 ml/20 min = x ml/60 min. Cross multiply to solve: 50 × 60 / 20 = 150 ml/hr. Therefore, the infusion pump should be set to deliver the secondary infusion at a rate of 150 ml/hr. Option A, 75 ml/hr, is incorrect because it does not account for the correct calculation. Option C, 225 ml/hr, is incorrect as it is too high a rate based on the calculation. Option D, 300 ml/hr, is also incorrect as it does not align with the correct calculation for the infusion rate.

3. 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.

4. During the assessment, a client receiving a continuous infusion of heparin for deep vein thrombosis (DVT) is found to have a nosebleed. Which finding requires immediate action?

• A. The client's activated partial thromboplastin time (aPTT) is 70 seconds.
• B. The client has developed a nosebleed.
• C. The client's blood pressure is 150/90 mm Hg.
• D. The client reports feeling lightheaded.

Correct answer: B

Rationale: A nosebleed (B) in a client receiving heparin is a sign of heparin toxicity and requires immediate action. It indicates that the client is at risk of excessive bleeding. While a prolonged aPTT of 70 seconds (A) is worth monitoring, active bleeding takes precedence. Elevated blood pressure (C) and lightheadedness (D) are potential side effects of heparin but are not as urgently concerning as active bleeding.

5. A client is receiving intravenous (IV) fluids postoperatively. Which assessment finding should prompt the nurse to stop the infusion and notify the healthcare provider?

• A. The client reports pain at the IV site
• B. The client’s blood pressure is elevated
• C. The client has swelling at the IV site
• D. The client’s heart rate is irregular

Correct answer: C

Rationale: Swelling at the IV site may indicate infiltration or phlebitis, which requires stopping the IV infusion and notifying the healthcare provider. Infiltration occurs when the IV fluid leaks into the surrounding tissue, causing swelling and potential damage. It is crucial to act promptly to prevent further complications and ensure the client's safety.
