1. A nurse is preparing to insert a small-bore nasogastric feeding tube for a client's enteral feedings. In which method does the nurse measure the correct length of the tube?

A. From the tip of the nose to the xiphoid process
B. From the tip of the nose to the earlobe to the xiphoid process
C. From the earlobe to the xiphoid process
D. From the tip of the nose to the earlobe to the umbilicus

Correct answer: B

Rationale: When preparing to insert a nasogastric tube, the nurse must measure the correct length to ensure that the end of the tube will be in the correct position in the stomach. The accurate method to measure the length is from the tip of the nose to the earlobe to the xiphoid process. This length ensures that the end of the tube reaches the stomach, avoiding placement in the small intestine or esophagus. Choice A is incorrect as it does not include the earlobe, which is essential for accurate measurement. Choice C is incorrect because measuring from the earlobe alone does not provide the correct length for positioning in the stomach. Choice D is incorrect as it includes the umbilicus, which is not the appropriate landmark for measuring the length of a nasogastric tube intended for stomach placement.

2. A patient in a clinic has been diagnosed with hepatitis A. What is the most likely route of transmission?

A. Sexual contact with an infected partner
B. Contaminated food
C. Blood transfusion
D. Illegal drug use

Correct answer: B

Rationale: The correct answer is contaminated food. Hepatitis A is primarily transmitted through the fecal-oral route, often through the ingestion of contaminated food or water. It is caused by the Hepatitis A virus (HAV), which is a single-stranded, positive-sense RNA virus. Sexual contact with an infected partner is more commonly associated with hepatitis B and C. Blood transfusion is a potential route for hepatitis B and C transmission due to bloodborne pathogens. Illegal drug use, particularly involving shared needles, is a common route for hepatitis C transmission.

3. When examining an older adult, which technique should the nurse use?

A. Minimize touching the patient as much as possible.
B. Attempt to perform the entire physical examination during one visit.
C. Speak loudly and slowly due to potential hearing deficits in aging adults.
D. Arrange the sequence of the examination to allow as few position changes as possible.

Correct answer: D

Rationale: When examining an older adult, it is crucial to arrange the sequence of the examination to minimize position changes. This helps prevent discomfort and fatigue for the older adult, who may have mobility issues. Option A is incorrect because physical touch is essential when examining older adults, as their other senses may be diminished. Option B is incorrect as it is better to break the examination into multiple visits to ensure thoroughness and comfort. Option C is incorrect because while some older adults may have hearing deficits, it is not appropriate to assume this for all individuals without proper assessment.

4. A patient's urine specimen tested positive for bilirubin. Which of the following is most true?

A. The patient should be evaluated for kidney disease
B. The specimen was probably left at room temperature for more than two hours
C. The specimen is positive for bacteria
D. The specimen should be stored in an area protected from light

Correct answer: D

Rationale: Bilirubin is easily broken down by light, so all samples testing positive for bilirubin should be protected from light exposure. Storing the specimen in an area protected from light helps maintain the integrity of the bilirubin levels for accurate testing. Choice A is incorrect because the presence of bilirubin in urine does not necessarily indicate kidney disease. Choice B is incorrect as the exposure to light, not room temperature, affects bilirubin levels. Choice C is incorrect as the presence of bilirubin does not indicate the presence of bacteria in the specimen.

5. When a sequence of repeated weights is necessary, the healthcare provider should aim to weigh the patient at the same time of day and with consistent clothing. Using a standardized balance or electronic standing scale is recommended for accurate measurements. The patient should remove shoes and heavy outer clothing. It is not required for the patient to always be weighed in undergarments. What is the most appropriate indicator of the patient's overall well-being?

A. General health
B. Genetic makeup
C. Nutritional status
D. Activity and exercise patterns

Correct answer: A

Rationale: Weight measurements are essential to assess general health, particularly in monitoring growth patterns. Height and weight recordings are crucial indicators of overall well-being, reflecting the individual's health status. Genetic makeup does not change with weight fluctuations, making it an inappropriate indicator. Nutritional status and activity levels can influence weight but are not as comprehensive as general health in reflecting overall well-being.
