Correct Answer: A

Rationale: Calcium carbonate should be taken with meals because it requires the presence of stomach acid to be properly absorbed. Taking it with meals helps ensure optimal absorption and effectiveness as a phosphate binder in patients with chronic kidney disease. Administering calcium carbonate on an empty stomach may lead to gastrointestinal side effects such as upset stomach, bloating, and constipation. Taking it with a full glass of water is also recommended to help prevent potential gastrointestinal issues and to ensure proper hydration. Crushing tablets before administration is not advised unless specifically instructed by a healthcare provider, as it can alter the drug's release and absorption properties.

Correct Answer: A

Rationale: Molluscum contagiosum is a viral skin infection caused by the poxvirus. It commonly presents as flesh-colored, dome-shaped papules with central umbilication on the face, trunk, and extremities. The central umbilication indicates the presence of a crater-like indentation in the center of the lesion. It is a benign condition and usually self-limited, but it can be persistent and contagious. Treatment options include cryotherapy, curettage, topical therapies, and observation. Acne vulgaris presents with comedones, papules, pustules, and nodules primarily on the face, chest, and back. Sebaceous hyperplasia is characterized by yellowish papules with central dell on the face. Basal cell carcinoma typically presents as a pearly papule with telangiectasias and may have ulceration or bleeding.

Correct Answer: C

Rationale: Pituitary adenoma is the most likely neurological condition responsible for the described symptoms of acute onset severe headache, visual disturbances, and altered mental status when a tumor is found compressing the optic chiasm. Pituitary adenomas are benign tumors arising from the pituitary gland located at the base of the brain. As the tumor grows, it can compress nearby structures such as the optic chiasm, leading to visual disturbances (due to pressure on the optic nerves), severe headache (due to increased intracranial pressure), and altered mental status (due to effects on nearby brain structures).

Correct Answer: C

Rationale: NSAIDs are commonly known to increase the risk of gastrointestinal adverse effects, including gastritis, ulcers, and gastrointestinal bleeding. This risk is due to the inhibition of prostaglandin synthesis, which plays a protective role in the gastrointestinal mucosa. Gastrointestinal bleeding can manifest as symptoms such as black, tarry stools, vomiting blood, or abdominal pain. Therefore, it is crucial for the nurse to closely monitor the patient for signs and symptoms of gastrointestinal bleeding while taking NSAIDs to prevent potentially serious complications. Hypotension, hyperkalemia, and hyperglycemia are not commonly associated with NSAIDs use, making them less likely adverse effects to monitor for in this scenario.

Correct Answer: C

Rationale: Cryptosporidium parvum is a protozoan parasite that commonly causes waterborne illness characterized by watery diarrhea, abdominal cramps, and nausea. This parasite is often transmitted through contaminated water sources such as streams or lakes. Laboratory tests identifying oocysts in the stool sample are indicative of Cryptosporidium infection. Giardia lamblia can also cause similar symptoms, but the presence of oocysts points more towards Cryptosporidium in this case. Entamoeba histolytica causes amoebic dysentery with bloody diarrhea and is usually associated with fecal-oral transmission through contaminated food or water. Cyclospora cayetanensis typically causes prolonged watery diarrhea and is associated with the ingestion of contaminated food or water.
