Nursing Elites

1. Which natural body defense plays an active role in preventing infection?

• A. Yawning
• B. Body hair
• C. Hiccupping
• D. Rapid eye movements

Correct answer: B

Rationale: Body hair plays an active role in preventing infection by acting as a filter to block pathogens. It helps to prevent harmful substances from entering the body through the skin, providing a physical barrier against potential infections.

2. A healthcare professional is caring for a client who is experiencing respiratory distress. Which of the following early manifestations of hypoxemia should the professional recognize?

• A. Confusion
• B. Pale skin
• C. Bradycardia
• D. Hypotension

Correct answer: B

Rationale: Pale skin is an early manifestation of hypoxemia due to decreased oxygenation of the blood. The skin may appear pale as the body redirects blood flow to vital organs in response to low oxygen levels. Confusion, bradycardia, and hypotension may occur as hypoxemia worsens, but pale skin is one of the initial signs that healthcare professionals should recognize when assessing a client experiencing respiratory distress.

3. A client has had a cast applied, and a nurse is providing care. Which of the following actions should the nurse take first?

• A. Place an ice pack over the cast.
• B. Palpate the pulse distal to the cast.
• C. Teach the client to keep the cast clean and dry.
• D. Position the casted extremity on a pillow.

Correct answer: B

Rationale: When caring for a client with a newly applied cast, the nurse's priority should be to assess the circulation by palpating the pulse distal to the cast. This is crucial to ensure there is no compromise in blood flow, which could lead to serious complications. Placing an ice pack over the cast, teaching the client about cast care, and positioning the casted extremity on a pillow are important interventions but should follow the assessment of circulation.

4. A client with tuberculosis is receiving a new prescription for isoniazid (INH). The nurse should instruct the client to report which of the following findings as an adverse effect of the medication?

• A. You might notice yellowing of your skin.
• B. You might experience pain in your joints.
• C. You might notice tingling of your hands.
• D. You might experience loss of appetite.

Correct answer: C

Rationale: Tingling of the hands is a common adverse effect of isoniazid (INH) due to its potential to cause peripheral neuropathy. This sensation can be an early sign of nerve damage, and thus, the client should be instructed to report it promptly to the healthcare provider for further evaluation and management.

5. What is the appropriate needle size for insulin injection?

• A. 18G, 1 ½” long
• B. 22G, 1” long
• C. 22G, 1 ½” long
• D. 25G, 5/8” long

Correct answer: D

Rationale: The appropriate needle size for insulin injection is 25G, 5/8” long. This size allows for accurate and comfortable insulin administration in subcutaneous tissue.
