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 healthcare professional is admitting a client who has influenza. Which of the following types of transmission precautions should the healthcare professional initiate?

• A. Airborne
• B. Droplet
• C. Contact
• D. Protective environment

Correct answer: B

Rationale: Droplet precautions should be initiated for clients with infections that spread via droplet nuclei larger than 5 microns in diameter, such as influenza, rubella, meningococcal pneumonia, and streptococcal pharyngitis. In the case of influenza, the virus is primarily spread through respiratory droplets produced when an infected person coughs, sneezes, or talks. Airborne precautions are used for pathogens that remain infectious over long distances, typically smaller than 5 microns, like tuberculosis. Contact precautions are for diseases transmitted by direct or indirect contact, and protective environment precautions are for immunocompromised individuals to protect them from environmental pathogens.

3. The nurse is caring for a client with diabetes insipidus. Which finding should the LPN/LVN report to the healthcare provider?

• A. Weight gain
• B. Increased urine output
• C. Low blood pressure
• D. Thirst

Correct answer: B

Rationale: The correct answer is B: Increased urine output. In diabetes insipidus, there is a deficiency of antidiuretic hormone (ADH), leading to the excretion of large amounts of dilute urine. Reporting increased urine output is crucial as it is a hallmark sign of diabetes insipidus. Weight gain (choice A) is not typically associated with diabetes insipidus; instead, clients may experience weight loss due to fluid loss. Low blood pressure (choice C) can be a complication of diabetes insipidus due to dehydration from excessive urination, but the priority finding to report is the increased urine output. Thirst (choice D) is a common symptom of diabetes insipidus due to the body's attempt to compensate for fluid loss, but it is not the most critical finding to report.

4. The nurse is caring for a client with a nasogastric (NG) tube. Which action should the nurse take to maintain patency of the tube?

• A. Flush the tube with 30 ml of water before and after medication administration.
• B. Administer the medication with food to prevent nausea.
• C. Verify tube placement by aspirating stomach contents.
• D. Dilute the medication with normal saline before administration.

Correct answer: A

Rationale: To maintain the patency of a nasogastric (NG) tube, it is essential to flush the tube with 30 ml of water before and after medication administration. This action helps ensure that the tube remains open and free from blockages. Flushing the tube prevents any medication residue from causing blockages, maintaining its patency. Choice B is incorrect because administering medication with food does not relate to maintaining tube patency. Choice C is incorrect as verifying tube placement by aspirating stomach contents is related to confirming correct tube placement, not maintaining patency. Choice D is also incorrect because diluting the medication with normal saline is not primarily aimed at maintaining the tube's patency.

5. A nurse is admitting a client who has an abdominal wound with a large amount of purulent drainage. Which of the following types of transmission precautions should the nurse initiate?

• A. Protective environment
• B. Airborne precautions
• C. Droplet precautions
• D. Contact precautions

Correct answer: D

Rationale: The correct answer is D: Contact precautions. When a client has an abdominal wound with purulent drainage, contact precautions are necessary to prevent the spread of infection through direct contact. Protective environment precautions are used for immunocompromised clients, airborne precautions are for diseases transmitted by airborne particles, and droplet precautions are for diseases transmitted by respiratory droplets. In this case, the focus is on preventing direct contact transmission, making contact precautions the most appropriate choice. Protective environment, airborne, and droplet precautions are not indicated in this scenario because the primary concern is the direct contact transmission of pathogens through the wound drainage.
