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 nurse is assessing a client who has syndrome of inappropriate antidiuretic hormone (SIADH). Which of the following findings should the nurse expect?

• A. Increased urine output
• B. Increased serum sodium
• C. Hyponatremia
• D. Hypercalcemia

Correct answer: C

Rationale: In clients with Syndrome of Inappropriate Antidiuretic Hormone (SIADH), the nurse should expect hyponatremia. SIADH leads to excess water retention, diluting the sodium levels in the blood, resulting in low serum sodium levels. Choice A, increased urine output, is incorrect as SIADH causes water retention, leading to decreased urine output. Choice B, increased serum sodium, is incorrect because SIADH causes a dilutional effect due to water retention, resulting in decreased serum sodium levels. Choice D, hypercalcemia, is unrelated to SIADH and not a typical finding.

3. What is the most important nursing intervention for a patient experiencing an acute asthma attack?

• A. Administer bronchodilators
• B. Provide supplemental oxygen
• C. Start IV fluids
• D. Monitor oxygen saturation

Correct answer: A

Rationale: The correct answer is to administer bronchodilators. During an acute asthma attack, bronchodilators like albuterol are crucial to help dilate the airways and improve breathing. Providing supplemental oxygen (Choice B) may be necessary but is not the priority intervention. Starting IV fluids (Choice C) and monitoring oxygen saturation (Choice D) are important aspects of care but are not the most critical interventions during an acute asthma attack.

4. Which assessment finding is most concerning in a patient receiving morphine?

• A. Hypotension
• B. Bradycardia
• C. Respiratory depression
• D. Hypertension

Correct answer: C

Rationale: The correct answer is C, respiratory depression. When a patient is receiving morphine, respiratory depression is the most concerning side effect because it can lead to serious complications, including respiratory arrest and even death. Monitoring the patient's respiratory status is crucial to ensure early detection of any signs of respiratory depression. Choices A, B, and D are incorrect because although hypotension, bradycardia, and hypertension can occur as side effects of morphine, they are not as immediately life-threatening as respiratory depression in this context.

5. A nurse is caring for a 1-day-old newborn who has jaundice and is receiving phototherapy. Which of the following actions should the nurse take?

• A. Feed the infant 30 ml (1 oz) of glucose water every 2 hours.
• B. Keep the infant's head uncovered.
• C. Ensure that the newborn wears a diaper.
• D. Apply lotion to the newborn every 4 hours.

Correct answer: C

Rationale: The correct action for the nurse to take is to ensure that the newborn wears a diaper. This is important to prevent irritation during phototherapy, as exposure to light can increase the risk of skin breakdown. Feeding the infant glucose water is unnecessary and not indicated for jaundice treatment. Keeping the infant's head uncovered allows the light to reach the skin effectively. Applying lotion to the newborn every 4 hours can interfere with the effectiveness of phototherapy and is not recommended.
