Nursing Elites

1. A healthcare professional is reviewing the laboratory values for a client who has a positive Chvostek's sign. Which of the following laboratory findings should the healthcare professional expect?

• A. Decreased calcium
• B. Elevated potassium
• C. Increased sodium
• D. Low hemoglobin

Correct answer: A

Rationale: A positive Chvostek's sign is a clinical indication of low calcium levels, known as hypocalcemia. This sign is elicited by tapping the facial nerve anterior to the ear, resulting in facial muscle twitching. The correct laboratory finding associated with a positive Chvostek's sign is decreased calcium. Elevated potassium (Choice B) is not typically associated with Chvostek's sign but can be seen in conditions like renal failure. Increased sodium (Choice C) is not directly related to Chvostek's sign and is more commonly associated with hypernatremia. Low hemoglobin (Choice D) is not the expected laboratory finding in a client with a positive Chvostek's sign; instead, it suggests anemia, which is unrelated to this clinical manifestation.

2. A client with type 2 diabetes mellitus is receiving metformin (Glucophage). Which laboratory test should the LPN/LVN monitor while the client is taking this medication?

• A. Complete blood count (CBC)
• B. Liver function tests
• C. Serum electrolytes
• D. Renal function tests

Correct answer: B

Rationale: The correct answer is B: Liver function tests. While a client is taking metformin, monitoring liver function tests is crucial to assess for potential hepatic side effects. Metformin is primarily eliminated by the liver, and monitoring liver function tests helps in early detection of any liver-related complications. Choices A, C, and D are incorrect. A complete blood count (CBC) is not specifically required for monitoring metformin therapy. Serum electrolytes are not directly impacted by metformin, making it less relevant for monitoring this medication. Renal function tests are important for some other diabetes medications, but in the case of metformin, liver function tests take precedence due to its hepatic metabolism.

3. A healthcare provider is assessing a client's ability to balance. Which of the following actions is appropriate when the healthcare provider conducts a Romberg test?

• A. Ask the client to extend their arms in front of their body.
• B. Ask the client to walk in a straight line heel to toe.
• C. Have the client stand with their feet together.
• D. Have the client place their hands on their hips.

Correct answer: C

Rationale: The Romberg test is a neurological test that assesses proprioception and balance. To perform this test, the client is asked to stand with their feet together and arms at their sides while closing their eyes. By removing visual input, the test challenges the vestibular and proprioceptive systems. Choices A, B, and D are incorrect because they do not align with the proper procedure for conducting the Romberg test. Extending arms in front, walking heel to toe, or placing hands on hips are not part of the Romberg test protocol and may introduce variables that could affect the assessment of balance.

4. The patient is being taught about flossing and oral hygiene. What instruction will the nurse include in the teaching session?

• A. Using waxed floss helps prevent bleeding
• B. Flossing removes plaque and tartar from the teeth
• C. Flossing at least 3 times a day is beneficial
• D. Applying toothpaste before flossing is harmful

Correct answer: B

Rationale: The correct answer is B. Flossing is essential for removing plaque and tartar between teeth, contributing to better oral hygiene. Choice A is not entirely accurate as waxed floss may not solely prevent bleeding. Flossing three times a day, as mentioned in choice C, can be excessive and unnecessary, while choice D is incorrect as applying toothpaste before flossing is not harmful but might not provide additional benefits.

5. A client is scheduled for hip surgery in an hour. Which of the following actions is the nurse’s priority?

• A. Ensure that the client signs the consent form.
• B. Lock the client’s valuables in a secure location.
• C. Verify the client’s lab values in the medical record.
• D. Administer the prescribed preoperative sedative.

Correct answer: A

Rationale: The nurse’s priority is to ensure that the client signs the consent form before the hip surgery. This is crucial as it ensures that the client has provided informed consent for the procedure. Locking valuables, verifying lab values, and administering sedatives are important tasks but ensuring consent takes precedence as it directly impacts the client’s right to make decisions about their care.
