1. The healthcare provider attaches a pulse oximeter to a client's fingers and obtains an oxygen saturation reading of 91%. Which assessment finding most likely contributes to this reading?

• A. BP 142/88 mmHg
• B. 2+ edema of fingers and hands
• C. Radial pulse volume is +3
• D. Capillary refill time is 2 seconds

Correct answer: B

Rationale: Edema in the fingers and hands can impede the proper functioning of the pulse oximeter, leading to a falsely low oxygen saturation reading. Edema alters the transmission of light through the tissues, affecting the accuracy of the measurement. Therefore, the presence of edema in the fingers and hands is the most likely factor contributing to the low oxygen saturation reading of 91%.

2. The healthcare provider is aware that malnutrition is a common problem among clients served by a community health clinic for the homeless. Which laboratory value is the most reliable indicator of chronic protein malnutrition?

• A. Low serum albumin level
• B. Low serum transferrin level
• C. High hemoglobin level
• D. High cholesterol level

Correct answer: A

Rationale: A low serum albumin level is the most reliable indicator of chronic protein malnutrition. Serum albumin levels reflect long-term protein status, and a significantly lowered level usually indicates ongoing protein deficiency. Other laboratory values, such as serum transferrin, hemoglobin, or cholesterol levels, may be affected by various factors and conditions, but serum albumin is a more specific marker for chronic protein malnutrition.

3. 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.

4. A client with a diagnosis of deep vein thrombosis (DVT) is receiving anticoagulation therapy. Which statement by the client indicates a need for further teaching?

• A. I should avoid eating green leafy vegetables.
• B. I should wear loose-fitting clothes to avoid pressure on my legs.
• C. I should avoid prolonged sitting or standing.
• D. I should continue taking my over-the-counter herbal supplements.

Correct answer: D

Rationale: The statement 'I should continue taking my over-the-counter herbal supplements' (D) indicates a need for further teaching because some herbal supplements can interact with anticoagulants, increasing the risk of bleeding. It is crucial to inform healthcare providers about all medications, including herbal supplements, to prevent adverse interactions. The other statements reflect appropriate understanding of precautions related to DVT and anticoagulation therapy.

5. A CVA (stroke) patient goes into respiratory distress and is placed on a ventilator. The client’s daughter arrives with a durable power of attorney and a living will that indicates there should be no extraordinary life-saving measures. What action should the nurse take?

• A. Refer to the risk manager
• B. Notify the healthcare provider
• C. Discontinue the ventilator
• D. Review the medical record

Correct answer: B

Rationale: In this situation, the nurse should notify the healthcare provider. The healthcare provider needs to be informed to review the legal documents provided by the patient's daughter, such as the durable power of attorney and living will, which specify the patient's wishes regarding life-saving measures. The healthcare provider will be responsible for making the appropriate decision based on the legal documents and the patient's current condition. Referring to the risk manager (choice A) is not necessary as the issue at hand pertains to the patient's medical care. Discontinuing the ventilator (choice C) without healthcare provider input could go against the patient's wishes and legal documents. Reviewing the medical record (choice D) may not provide immediate guidance on the current situation and the patient's preferences regarding life-saving measures.
