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 is immediately postoperative following a subtotal thyroidectomy. Which of the following should the nurse expect to administer?

• A. Calcium gluconate
• B. Sodium bicarbonate
• C. Potassium chloride
• D. Sodium phosphate

Correct answer: A

Rationale: Calcium gluconate is the correct answer because it is administered to treat hypocalcemia, a common complication post-thyroidectomy. After a thyroidectomy, there is a risk of damaging the parathyroid glands, which can lead to a decrease in calcium levels. Administering calcium gluconate helps to raise calcium levels. Sodium bicarbonate (Choice B) is not typically indicated for immediate postoperative care following a subtotal thyroidectomy. Potassium chloride (Choice C) is not directly related to the common complications of this specific surgery. Sodium phosphate (Choice D) is not typically used to address immediate postoperative issues post-thyroidectomy.

3. A nurse is caring for a client who is at 32 weeks of gestation and has preeclampsia. Which of the following findings should the nurse report to the provider?

• A. Blood pressure of 120/80 mm Hg
• B. Respiratory rate of 16/min
• C. 1+ protein in the urine
• D. Heart rate of 88/min

Correct answer: C

Rationale: The correct answer is C. 1+ protein in the urine is indicative of worsening preeclampsia and should be reported to the provider immediately. Elevated blood pressure (choice A) is expected in preeclampsia, but a reading of 120/80 mm Hg is within the normal range. A respiratory rate of 16/min (choice B) and a heart rate of 88/min (choice D) are also within normal limits and not indicative of worsening preeclampsia.

4. A nurse is providing discharge instructions to a client who has a new prescription for warfarin. Which of the following statements indicates a need for further teaching?

• A. I will avoid leafy green vegetables while taking warfarin.
• B. I will have my INR checked regularly while taking warfarin.
• C. I will use a soft toothbrush while taking warfarin.
• D. I will take this medication at the same time each day.

Correct answer: A

Rationale: The correct answer is A. Clients taking warfarin should avoid leafy green vegetables because they are high in vitamin K, which can interfere with the effectiveness of warfarin by counteracting its anticoagulant effects. Choices B, C, and D are all correct statements related to taking warfarin. Regular INR monitoring is necessary to ensure the medication is within the therapeutic range, using a soft toothbrush reduces the risk of bleeding gums, and taking the medication at the same time daily helps maintain consistent blood levels.

5. A nurse is assessing a client who is 2 hours postoperative following a gastrectomy. Which of the following findings should the nurse report to the provider?

• A. Heart rate of 94/min
• B. Oxygen saturation of 88%
• C. Respiratory rate of 18/min
• D. Temperature of 37.6°C (99.7°F)

Correct answer: B

Rationale: An oxygen saturation of 88% indicates hypoxemia, which is a serious condition post-gastrectomy. Hypoxemia can lead to inadequate oxygen delivery to tissues, potentially causing complications like organ dysfunction or failure. This finding requires immediate attention to prevent further deterioration. The heart rate, respiratory rate, and temperature are within normal ranges for a client post-gastrectomy, so they do not require immediate reporting to the provider.
