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.

Correct Answer: B

Rationale: The correct answer is B because the client should exhale quickly and forcefully into the peak flow meter after taking a deep breath to measure peak expiratory flow. Choice A is incorrect as blowing as hard as possible may not provide an accurate reading. Choice C is incorrect because inhaling deeply before blowing can affect the results. Choice D is incorrect as holding the breath before exhaling is not part of using a peak flow meter.

Correct Answer: D

Rationale: The correct answer is D: 'Serosanguineous wound drainage.' Serosanguineous drainage should be reported in postoperative clients as it may indicate complications such as infection or impaired wound healing. Options A, B, and C are expected findings in a postoperative client. Bowel sounds present in all four quadrants indicate normal gastrointestinal function, a temperature of 37.5°C (99.5°F) is within the normal range, and scant urine output may be expected initially due to factors like anesthesia and fluid shifts postoperatively.

Correct Answer: A

Rationale: The best nursing intervention for a patient experiencing fluid overload is to administer diuretics. Diuretics help the body to remove excess fluid by increasing urine output. This intervention is crucial in managing fluid overload. Administering IV fluids (Choice B) would worsen the condition by adding more fluids to the already overloaded system. Providing oral fluids (Choice C) is not appropriate as it would further contribute to the fluid overload. Chest physiotherapy (Choice D) is not indicated in the treatment of fluid overload and would not address the underlying issue of excess fluid accumulation.
