1. Which diagnostic test is used to confirm tuberculosis (TB) infection?
- A. Chest X-ray
- B. Sputum culture
- C. Skin test (Mantoux)
- D. MRI
Correct answer: C
Rationale: The Mantoux skin test, also known as the Tuberculin Skin Test (TST), is used to confirm tuberculosis (TB) infection. This test involves injecting a small amount of tuberculin protein derivative under the top layer of the skin and then evaluating the immune system's response to the protein. A positive reaction indicates exposure to the TB bacteria. Chest X-rays are used to detect abnormalities in the lungs caused by TB but are not confirmatory. Sputum culture is used to identify the presence of TB bacteria in the sputum. MRIs are not typically used as a primary diagnostic tool for TB.
2. What is the most important assessment for a patient post-surgery?
- A. Monitor vital signs
- B. Check surgical site for bleeding
- C. Check for abnormal breath sounds
- D. Check skin color
Correct answer: A
Rationale: The correct answer is to monitor vital signs post-surgery. Vital signs provide crucial information about a patient's physiological status, helping detect early signs of complications such as shock, bleeding, or infection. Checking the surgical site for bleeding is important but falls secondary to monitoring vital signs, which give a broader overview of the patient's condition. Checking for abnormal breath sounds and skin color are also important assessments, but they are not as immediate and general as monitoring vital signs in detecting various post-surgical complications.
3. A nurse is preparing to administer an IV medication to a client who has an allergy to latex. Which of the following actions should the nurse take?
- A. Use latex gloves when administering the medication.
- B. Use latex-free syringes when administering the medication.
- C. Administer the medication through a latex-free IV port.
- D. Administer the medication with a latex-free syringe.
Correct answer: C
Rationale: The correct action for the nurse to take when preparing to administer IV medication to a client with a latex allergy is to administer the medication through a latex-free IV port. This is crucial as it prevents direct contact of the medication with latex, reducing the risk of an allergic reaction. Choice A is incorrect as using latex gloves can still expose the client to latex. Choice B is not the best option since the administration route is not specified, and using a latex-free syringe alone may not be sufficient to prevent exposure. Choice D is not the most appropriate because the IV tubing and ports should also be latex-free to ensure complete avoidance of latex contact.
4. A nurse is reviewing the medical record of a client who is receiving total parenteral nutrition (TPN). Which of the following findings should the nurse report to the provider?
- A. Glucose 180 mg/dL
- B. Sodium 136 mEq/L
- C. Potassium 3.8 mEq/L
- D. Albumin 3.5 g/dL
Correct answer: A
Rationale: The correct answer is A: "Glucose 180 mg/dL." Elevated glucose levels in a client receiving TPN may indicate hyperglycemia, which can lead to complications such as osmotic diuresis, dehydration, and electrolyte imbalances. It is essential to report this finding to the provider for further evaluation and management. Choices B, C, and D are within normal ranges and do not indicate immediate concerns related to TPN administration.
5. A nurse is planning to teach a group of clients about preventing low back pain. Which of the following information should the nurse include?
- A. Wear low-heeled shoes.
- B. Elevate the legs while sitting.
- C. Engage in prolonged sitting to rest the back muscles.
- D. Sleep on a soft mattress to prevent strain on the back.
Correct answer: A
Rationale: The correct answer is A: 'Wear low-heeled shoes.' Wearing low-heeled shoes helps prevent back strain by promoting proper posture. High heels can cause an imbalance in the body's alignment, leading to increased stress on the lower back. Choices B, C, and D are incorrect. Elevating the legs while sitting can help with circulation but does not directly prevent low back pain. Engaging in prolonged sitting can actually contribute to low back pain due to decreased muscle activity and increased pressure on the spine. Sleeping on a soft mattress may not provide adequate support for the back, potentially worsening back pain instead of preventing it.
