Which of the following tests is contraindicated for pregnant women?

Correct Answer: C

Rationale: The correct answer is C: Radionuclide imaging. This test involves exposing the patient to radiation, which can be harmful to the developing fetus. Pregnant women should avoid unnecessary exposure to radiation to prevent potential harm to the baby. A: Barium enema and B: Barium swallow involve the use of contrast material that is generally considered safe during pregnancy as it does not expose the fetus to radiation. D: Gallbladder series test, such as ultrasound or MRI, are also safe for pregnant women as they do not involve radiation exposure.

Correct Answer: B

Rationale: The correct answer is B because limiting foods that activate the bowel can help reduce the chances of embarrassing situations during sexual activity. Certain foods can cause gas or increase stool output, which may affect the client's confidence and comfort. Leaving the stoma open to air and covering with a towel (choice A) is not recommended during sexual activity as it may lead to odor and potential leakage. Bathing and applying a fresh pouch after sex (choice C) is important for hygiene but does not directly address preparation for sexual activity. Consulting with an ostomy support group (choice D) is beneficial for emotional support but does not specifically address strategies for anticipating sexual activity.

Correct Answer: D

Rationale: The correct answer is D: Severe anorexia resulting from radiation therapy. This patient has the highest risk for poor nutritional balance due to the severe anorexia caused by the treatment. Radiation therapy often leads to loss of appetite, making it difficult for the patient to ingest adequate nutrients, resulting in malnutrition. A: Tuberculosis infection does not necessarily directly cause decreased ingestion, as appetite may vary among patients. B: Draining decubitus ulcers may lead to protein and fluid loss but not necessarily decreased ingestion. C: Malabsorption syndrome affects the absorption of nutrients but does not directly relate to decreased ingestion.

Correct Answer: D

Rationale: The correct answer is D because providing adequate support to the incision during coughing, deep breathing, and turning is essential postoperatively to prevent complications such as wound dehiscence or infection in obese patients who have undergone bariatric surgery. Supporting the incision helps reduce stress on the surgical site and promotes proper healing. Choice A is incorrect because irrigating and repositioning the nasogastric tube is not a specific nursing intervention related to the care of the incision after bariatric surgery. Choice B is incorrect because delaying ambulation can increase the risk of complications such as deep vein thrombosis and pneumonia in postoperative obese patients. Choice C is incorrect because keeping the patient positioned on the side to facilitate respiratory function is important, but it is not directly related to supporting the incision during activities that increase intra-abdominal pressure.

Correct Answer: D

Rationale: The correct answer is D because corticosteroids inhibit the synthesis of mucus and prostaglandins, which are important for protecting the stomach lining. Without enough mucus and prostaglandins, the stomach lining becomes more susceptible to damage from stomach acid, leading to the development of peptic ulcers. Choice A is incorrect because the enzyme urease is associated with the development of Helicobacter pylori infection, not peptic ulcers directly. Choice B is incorrect because corticosteroids actually decrease hydrochloric acid secretion. Choice C is incorrect because a decreased rate of mucous cell renewal would lead to decreased mucus production, which could contribute to peptic ulcers, but it is not the primary mechanism associated with corticosteroids.
