1. The nurse is teaching a client about communicable diseases and explains that a portal of entry is:

• A. a vector.
• B. a source, like contaminated water.
• C. food.
• D. the respiratory system.

Correct answer: D

Rationale: The correct answer is 'the respiratory system.' A portal of entry is the path through which a microorganism enters the body. In the case of communicable diseases, the respiratory system can serve as a portal of entry for pathogens such as viruses or bacteria. Choices A, B, and C are incorrect. A 'vector' is an organism that transmits disease, not the entry point for pathogens. Contaminated water or food can act as sources or reservoirs of disease-causing microorganisms, not portals of entry.

2. The nurse is transferring a client from a wheelchair to the bed. Which is the correct procedure?

• A. Pull the client toward you, and pivot him on the unaffected limb.
• B. Pull the client toward you, and pivot him on the affected limb.
• C. Push the client toward the bed, and pivot him on the affected limb.
• D. Stand the client on both legs, and push him toward the bed.

Correct answer: A

Rationale: When transferring a client from a wheelchair to the bed, the correct procedure is to pull the client toward you, which reduces workload force. By pivoting the client on the unaffected limb, strength is maintained to support the affected limb while moving towards the bed. Choice A is correct because it ensures a safe and effective transfer technique. Choices B, C, and D are incorrect as they involve incorrect positioning and movements that could potentially harm the client or increase the risk of injury. Pulling the client towards you puts less strain on your back and reduces the risk of injury. Pivoting on the unaffected limb ensures better support for the client's affected limb during the transfer process.

3. Which of the following is not a function of parathyroid hormone?

• A. moving calcium from bones to the bloodstream
• B. inhibiting renal tubular reabsorption of phosphorus
• C. promoting renal tubular reabsorption of calcium
• D. enhancing renal production of vitamin D metabolites

Correct answer: B

Rationale: The correct answer is 'inhibiting renal tubular reabsorption of phosphorus.' Parathyroid hormone actually inhibits renal tubular reabsorption of phosphorus, making this choice the opposite of its function. Parathyroid hormone functions to move calcium from bones to the bloodstream (Choice A), promote renal tubular reabsorption of calcium (Choice C), and enhance renal production of vitamin D metabolites (Choice D). Therefore, all other choices are functions of parathyroid hormone except for the inhibition of phosphorus reabsorption.

4. All of the following clients are in need of an emergency assessment except:

• A. a bleeding client who has an injury from falling debris.
• B. an unresponsive client.
• C. a client with an old injury.
• D. a pregnant woman with imminent delivery.

Correct answer: C

Rationale: The correct answer is 'a client with an old injury.' Emergency assessments are required for immediate and life-threatening situations. Clients A, B, and D are in need of emergency assessments due to their critical conditions. Choice C, a client with an old injury, does not require an emergency assessment as it is not an acute or life-threatening situation. While the client with an old injury may still need medical attention, it does not necessitate an emergency assessment as the condition is not currently life-threatening or in need of immediate intervention.

5. Why is monitoring Serum Vancomycin levels important?

• A. to assess renal function
• B. to determine therapeutic range
• C. to measure trough levels
• D. to evaluate antibiotic resistance

Correct answer: B

Rationale: Monitoring Serum Vancomycin levels is essential to determine the drug's therapeutic range, ensuring optimal effectiveness while avoiding toxicity. Peak levels indicate the drug's highest concentration, while trough levels represent the lowest concentration before the next dose. Assessing renal function is typically done using creatinine, BUN, or creatinine clearance tests, not Serum Vancomycin levels. Evaluating antibiotic resistance involves sensitivity testing, not monitoring Vancomycin levels. Therefore, the correct answer is to determine the therapeutic range.
