Nursing Elites

1. A nurse at a health fair is assessing the weight status of four clients. Which of the following clients is classified as overweight?

• A. A female client who has a body mass index of 24
• B. A male client who has a body mass index of 29
• C. A female client who has a waist circumference of 101.6 cm (40 in)
• D. A male client who has a waist circumference of 96.52 cm (38 in)

Correct answer: B

Rationale: A body mass index (BMI) of 25 or higher is classified as overweight. Choice B, a male client with a BMI of 29, falls into the overweight category. Choice A, a female client with a BMI of 24, is within the normal range. Choices C and D provide information on waist circumference, which is not sufficient to determine if a client is overweight or not, as waist circumference alone does not provide the overall picture of weight status compared to BMI.

2. Glucagon is a hormone released into the bloodstream in response to high blood sugar. It helps to lower blood glucose after a meal.

• A. TRUE
• B. FALSE
• C.
• D.

Correct answer: B

Rationale: Glucagon is released in response to low blood sugar and raises blood glucose levels by stimulating the release of glucose from liver stores, not lowering it.

3. Which of the following vaccines is not done by intramuscular (IM) injection?

• A. Measles vaccine C. Hepa-B vaccine
• B. DPT D. Tetanus toxoids
• C.
• D.

Correct answer: D

Rationale: Understanding the underlying pathology and therapeutic techniques ensures that nursing care is not only reactive but also preventative, reducing the risk of complications.

4. A healthcare professional has just inserted an NG tube for a client who is to start enteral tube feedings. Which of the following actions should the healthcare professional take to verify tube placement?

• A. Measure the tube length.
• B. Obtain an abdominal x-ray.
• C. Flush the tube with 20 mL of water.
• D. Auscultate the client’s lungs.

Correct answer: B

Rationale: Obtaining an abdominal x-ray is the most accurate method to verify the correct placement of an NG tube. Measuring the tube length is not a reliable method to confirm placement as it may vary among individuals. Flushing the tube with water and auscultating the client's lungs are not definitive methods to ensure proper NG tube placement.

5. Before Dianne performs the formal research study, what do you call the pre-testing, small-scale trial run to determine the effectiveness of data collection and methodological problems that might be encountered?

• A. Sampling
• B. Pre-testing
• C. Pre-Study
• D. Pilot Study

Correct answer: D

Rationale: The correct answer is 'Pilot Study.' A pilot study is a small-scale trial run conducted before the formal research study to identify and address any issues related to data collection and methodology. This helps in determining the effectiveness of the research process and identifying potential problems that may arise. Choice A, 'Sampling,' refers to the process of selecting a subset of individuals from a larger population for research. Choice B, 'Pre-testing,' simply involves testing something before the main testing phase. Choice C, 'Pre-Study,' is not a commonly used term in research methodology and does not specifically refer to the small-scale trial run described in the question.
