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. A client with a history of depression and experiencing a situational crisis is being assessed by a nurse. What action should the nurse take first?

• A. Notify the client's support system.
• B. Help the client identify personal strengths.
• C. Confirm the client's perception of the event.
• D. Teach the client relaxation techniques.

Correct answer: A

Rationale: When a client with a history of depression is experiencing a situational crisis, the first action the nurse should take is to notify the client's support system. This is crucial as the client may require immediate assistance and support. While helping the client identify personal strengths and confirming the client's perception of the event are important aspects of the assessment and intervention process, notifying the support system takes priority in ensuring the client's safety and well-being. Teaching relaxation techniques may be beneficial but addressing the client's immediate crisis through support system notification is the most appropriate initial action.

3. A nurse is assessing a client who has a potassium level of 3.0 mEq/L. Which of the following findings should the nurse expect?

• A. Diarrhea
• B. Muscle weakness
• C. Hypertension
• D. Bradycardia

Correct answer: B

Rationale: Muscle weakness is a common finding in clients with hypokalemia, as potassium is essential for proper muscle function. Diarrhea (choice A) is more commonly associated with hyperkalemia rather than hypokalemia. Hypertension (choice C) is not typically a direct result of low potassium levels. Bradycardia (choice D) is more commonly associated with hyperkalemia, not hypokalemia.

4. A client with Parkinson's disease is receiving physical therapy. Which statement by the client indicates the need for a referral to physical therapy?

• A. I have been experiencing more tremors in my left arm than before
• B. I noticed that I am having a harder time holding onto my toothbrush
• C. Lately, I feel like my feet are freezing up, as they are stuck to the ground
• D. Sometimes, I feel I am making a chewing motion when I'm not eating

Correct answer: C

Rationale: The correct answer is C because freezing of feet while walking is a sign of impaired mobility, indicating the need for physical therapy in clients with Parkinson's disease. Choices A, B, and D are symptoms commonly associated with Parkinson's disease but do not specifically indicate the need for immediate referral to physical therapy.

5. A client has a stage 3 pressure injury. Which of the following interventions should the nurse include in the plan?

• A. Cleanse the wound with povidone-iodine solution daily.
• B. Irrigate the wound with hydrogen peroxide.
• C. Reposition the client every 4 hours.
• D. Apply a moisture barrier ointment.

Correct answer: D

Rationale: The correct intervention for a client with a stage 3 pressure injury is to apply a moisture barrier ointment. This helps protect the skin, maintain moisture balance, and promote healing. Choice A is incorrect because povidone-iodine solution can be too harsh for wound care. Choice B is incorrect as hydrogen peroxide can be cytotoxic to healing tissue. Choice C is important for preventing pressure injuries but is not a direct intervention for a stage 3 wound.
