1. Which is the proper hand position for performing chest percussion?

A. Use the side of the hands
B. Flatten the hands
C. Spread the fingers of both hands
D. Cup the hands

Correct answer: D

Rationale: The proper hand position for performing chest percussion is to cup the hands. Cupping the hands helps produce a vibration that aids in loosening respiratory secretions effectively. This technique is essential for therapeutic chest physiotherapy. Using the side of the hands, flattening the hands, or spreading the fingers of both hands do not generate the necessary vibration required for chest percussion. These hand positions are not considered proper techniques in this context and may not provide the desired therapeutic effect.

2. 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.

3. An example of a process standard on a med-surg unit is:

A. a procedure for changing IV tubing.
B. a policy for staffing.
C. the job description of the CEO (chief executive officer).
D. a procedure for checking waveforms on a client being treated with an intra-aortic balloon pump.

Correct answer: D

Rationale: Process standards define the actions and behaviors required by staff to provide care on a med-surg unit. A procedure for changing IV tubing is a critical psychomotor skill necessary for safe and effective patient care in this setting. Choice B, a policy for staffing, pertains more to organizational management rather than specific care processes on the unit. Choice C, the job description of the CEO, delineates the responsibilities of the organization's top executive and is not a process standard for frontline staff. Choice D, a procedure for checking waveforms on a client with an intra-aortic balloon pump, is more specific to a cardiac care unit and not typically performed on a med-surg unit.

4. The LPN is auscultating for bowel sounds and hears between 3 and 4 bowel sounds per minute. This is a somewhat expected finding for which of these clients?

A. a 63-year-old female undergoing chemotherapy for breast cancer
B. a 56-year-old female with dementia undergoing a swallow study
C. a 34-year-old male with a PEG tube newly admitted for diabetic ketoacidosis
D. a 45-year-old male recovering from a knee replacement under general anesthesia

Correct answer: D

Rationale: When recovering from general anesthesia, hypoactive bowel sounds can be expected due to the effects of the anesthesia on gut motility. For the other clients, hearing less than 5 bowel sounds per minute would indicate an abnormal finding. In the context of the given situation, the client recovering from knee replacement surgery aligns with the expected range of bowel sounds post-general anesthesia. Therefore, choice D is the correct answer. Choices A, B, and C present scenarios where hearing less than 5 bowel sounds per minute would be abnormal, indicating potential issues that need further evaluation.

5. How many temporary teeth should the nurse expect to find in a 5-year-old client's mouth?

A. up to 10
B. up to 15
C. up to 20
D. up to 32

Correct answer: C

Rationale: A 5-year-old child can have up to 20 temporary (deciduous or baby) teeth. The first tooth usually erupts by age 6 months, and the last by age 30 months. All temporary teeth are usually shed between 6 and 13 years of age. Therefore, a 5-year-old child should have up to 20 temporary teeth. The correct answer is 'up to 20.' Choices A, B, and D are incorrect because the correct number of temporary teeth in a 5-year-old child's mouth is up to 20, not 10, 15, or 32.
