Nursing Elites

1. What type of blood pressure measurement error is most likely to occur if the nurse does not check for the presence of an auscultatory gap?

• A. Diastolic blood pressure may not be heard.
• B. Diastolic blood pressure may be falsely low.
• C. Systolic blood pressure may be falsely low.
• D. Systolic blood pressure may be falsely high.

Correct answer: C

Rationale: If an auscultatory gap is undetected, a falsely low systolic reading may occur. This gap can lead to an underestimation of the systolic blood pressure, causing potential misinterpretation of the patient's condition. The diastolic blood pressure may not be heard due to the gap, but the critical issue in this scenario is the risk of underestimating systolic blood pressure, which can impact clinical decision-making. Choices B, C, and D are incorrect because the key concern in this context is the potential for a falsely low systolic blood pressure reading when an auscultatory gap is not assessed.

2. You are preparing to admit a patient with a seizure disorder. Which of the following actions can you delegate to an LPN/LVN?

• A. Complete admission assessment.
• B. Set up oxygen and suction equipment.
• C. Place a padded tongue blade at the bedside.
• D. Pad the side rails before the patient arrives.

Correct answer: B

Rationale: The correct answer is to delegate the task of setting up oxygen and suction equipment to the LPN/LVN. This task falls within their scope of practice and can be safely performed by them. Completing the admission assessment (Choice A) typically requires a higher level of assessment and critical thinking, making it more appropriate for a registered nurse. Placing a padded tongue blade at the bedside (Choice C) involves potential airway management, which is a more complex task and should be done by a higher-level provider. Padding the side rails before the patient arrives (Choice D) is a task related to patient safety and should be done by the healthcare team as a whole, not solely delegated to an LPN/LVN.

3. 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.

4. Which of the following is a negative outcome associated with impaired mobility?

• A. Increased amounts of calcium are absorbed from circulation
• B. A drop in blood pressure occurs when rising from a sitting to a standing position
• C. The amount of mucus in the bronchi and lungs decreases
• D. The vessel walls of the circulatory system thicken

Correct answer: B

Rationale: A client with impaired mobility may develop changes in body systems that put them at risk of further illness or injury. One negative outcome associated with impaired mobility is orthostatic hypotension, where blood pressure drops significantly when moving from a sitting or lying position to a standing position. This drop in blood pressure can lead to symptoms such as dizziness or fainting. This occurs because blood circulates more slowly or pools in the distal extremities due to impaired mobility. Choice A is incorrect because increased calcium absorption is not a typical negative outcome associated with impaired mobility. Choice C is incorrect because a decrease in mucus in the bronchi and lungs is not a common negative outcome of impaired mobility. Choice D is incorrect because thickening of vessel walls in the circulatory system is not directly associated with impaired mobility.

5. Which vacutainer tubes should be used when a requisition calls for blood to be drawn for an H&H and glucose test?

• A. One light blue, one red
• B. Two lavenders
• C. One lavender, one grey
• D. One green, one red

Correct answer: D

Rationale: The correct answer is 'One green, one red.' An H&H test involves hemoglobin and hematocrit, which are components of a complete blood count and are typically drawn in a lavender tube. On the other hand, blood for glucose testing is collected in grey tubes. Therefore, when drawing blood for both an H&H and glucose test, one green tube for glucose and one red tube for H&H should be used. The other choices are incorrect because light blue tubes are used for coagulation studies, lavender tubes are for complete blood counts, and green tubes are for chemistry tests like glucose, while grey tubes are specifically for glucose testing.
