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. The healthcare professional is preparing to administer a tuberculin skin test. Which site is most appropriate for this injection?

• A. Deltoid muscle
• B. Vastus lateralis muscle
• C. Abdomen
• D. Inner forearm

Correct answer: D

Rationale: The inner forearm is the most appropriate site for administering a tuberculin skin test. This test requires an intradermal injection, which is administered just below the surface of the skin. The inner forearm provides a flat, easily accessible surface for this type of injection. Choices A, B, and C are incorrect because the tuberculin skin test should not be administered into a muscle (deltoid muscle or vastus lateralis muscle) or into the abdomen. The test requires precise placement within the dermal layer of the skin on the inner forearm to accurately assess for a reaction.

3. The LPN/LVN is caring for a client with chronic obstructive pulmonary disease (COPD) who is receiving oxygen therapy. Which observation indicates that the client is experiencing oxygen toxicity?

• A. Nasal congestion
• B. Cough
• C. Sore throat
• D. Fatigue

Correct answer: C

Rationale: The correct answer is 'C: Sore throat.' Oxygen toxicity can manifest with symptoms like a sore throat, cough, chest pain, difficulty breathing, and fatigue. However, a sore throat can be an early indicator of oxygen toxicity and should prompt immediate attention. Nasal congestion, cough, and fatigue are not specific indicators of oxygen toxicity but could be related to other factors in a client with COPD receiving oxygen therapy.

4. The healthcare professional is caring for a client with a chest tube. Which observation requires immediate intervention?

• A. Constant bubbling in the suction control chamber
• B. Intermittent bubbling in the water seal chamber
• C. Drainage of 50 ml per hour
• D. Crepitus around the insertion site

Correct answer: D

Rationale: Crepitus around the chest tube insertion site may indicate subcutaneous emphysema, which requires immediate attention. The presence of crepitus suggests air leaking into the tissues, which could lead to respiratory compromise. Constant bubbling in the suction control chamber is expected and indicates proper functioning of the chest tube system. Intermittent bubbling in the water seal chamber is also normal, showing the system is intact. Drainage of 50 ml per hour is within the expected range for a chest tube.

5. During a physical assessment on a toddler, what should be the first action?

• A. Perform traumatic procedures
• B. Use minimal physical contact
• C. Proceed from head to toe
• D. Explain the exam in detail

Correct answer: B

Rationale: The correct first action when performing a physical assessment on a toddler is to use minimal physical contact. This approach helps the toddler become comfortable and reduces anxiety during the assessment. Traumatic procedures (Choice A) should never be the first action as they can cause distress. Proceeding from head to toe (Choice C) is a common sequence in physical assessments but does not address the initial need to establish trust and comfort. Explaining the exam in detail (Choice D) is important but should come after establishing a rapport through minimal physical contact.
