Nursing Elites

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 who is taking phenytoin is being taught about contraceptive options. Which of the following statements should the nurse make?

• A. You should use a backup method of birth control while taking phenytoin.
• B. Phenytoin can decrease the effectiveness of oral contraceptives.
• C. You should stop taking phenytoin while using oral contraceptives.
• D. Phenytoin can increase the effectiveness of oral contraceptives.

Correct answer: B

Rationale: The correct answer is B. Phenytoin can decrease the effectiveness of oral contraceptives, so it is important to inform the client about this interaction. Using an additional form of contraception, such as a backup method, is recommended to ensure adequate protection against pregnancy. Choice A is incorrect because it lacks specificity about the decrease in effectiveness of oral contraceptives caused by phenytoin. Choice C is incorrect as it suggests stopping phenytoin use while using oral contraceptives, which is not the appropriate action. Choice D is incorrect as phenytoin is known to decrease, not increase, the effectiveness of oral contraceptives.

3. A nurse is providing teaching to a client who has osteoporosis. Which of the following instructions should the nurse include?

• A. Take a calcium supplement once daily.
• B. Walk for 30 minutes three times per week.
• C. Avoid weight-bearing exercises.
• D. Increase intake of vitamin D.

Correct answer: B

Rationale: The correct answer is B. Walking regularly is beneficial for clients with osteoporosis as it helps maintain bone density and prevent fractures. Choice A is not the most appropriate because clients with osteoporosis often require more than just calcium supplements. Choice C is incorrect as weight-bearing exercises actually help strengthen bones. Choice D is important, but walking regularly has a more direct impact on bone health in clients with osteoporosis.

4. A client post-thyroidectomy reports tingling in their lips and fingers. The nurse should identify this finding as an indication of which of the following complications?

• A. Hypokalemia
• B. Hypocalcemia
• C. Hyponatremia
• D. Hyperglycemia

Correct answer: B

Rationale: Tingling in the lips and fingers is a classic sign of hypocalcemia, which can occur as a complication following a thyroidectomy due to inadvertent damage to the parathyroid glands that regulate calcium levels. Hypokalemia (Choice A) presents with muscle weakness and cardiac issues, not tingling. Hyponatremia (Choice C) typically manifests with confusion, seizures, and muscle cramps. Hyperglycemia (Choice D) is associated with increased thirst, frequent urination, and fatigue.

5. How should fluid balance in a patient with heart failure be monitored?

• A. Monitor daily weight
• B. Monitor input and output
• C. Check for edema
• D. Monitor blood pressure

Correct answer: A

Rationale: The correct answer is to monitor daily weight. Daily weight monitoring is crucial in assessing fluid balance in patients with heart failure because sudden weight gain can indicate fluid retention. Monitoring input and output (choice B) is important but may not provide a complete picture of fluid balance. Checking for edema (choice C) is a sign of fluid accumulation but may not be as accurate as daily weight monitoring. Monitoring blood pressure (choice D) is important in heart failure management but does not directly assess fluid balance.
