Correct Answer: D

Rationale: The correct answer is D: Administer corticosteroids. In a client with chest pain and a history of myocardial infarction, the first priority is to address potential inflammation in the myocardium. Corticosteroids help reduce inflammation and stabilize the myocardium, which is crucial in preventing further damage post-myocardial infarction. Administering nitroglycerin (A) is important for vasodilation, but it is typically used after corticosteroids. Morphine (B) and analgesics (C) may provide pain relief but do not address the underlying inflammation. Administering corticosteroids is the most appropriate first step to manage myocardial inflammation and protect the heart tissue.

Correct Answer: A

Rationale: The correct answer is A (3 years old) because the Nipissing District Developmental Screen is specifically designed for children aged 1 month to 6 years to assess their developmental milestones. It focuses on various areas of development appropriate for this age group, such as motor skills, language, social interaction, and cognitive abilities. Using this tool with a 3-year-old child allows for early identification of potential developmental delays or concerns. Incorrect choices: B (16 years old) - The Nipissing District Developmental Screen is not intended for children above 6 years old. C (8 years old with a developmental delay) - The tool is primarily for early screening, not for children already identified with developmental delays. D (Having difficulty with gross motor skills) - While this child may benefit from assessment, the Nipissing Screen is a comprehensive tool for overall development, not just specific skill deficits.

Correct Answer: D

Rationale: The correct answer is D because all choices (A, B, and C) can increase the risk of STDs. Alcohol use can impair judgment leading to risky sexual behavior. Certain sexual practices (such as unprotected sex or having multiple partners) can directly increase the risk of STD transmission. Oral contraception does not protect against STDs, so individuals relying solely on it may still be at risk. Therefore, all of the above factors can contribute to an increased risk of contracting STDs.

Correct Answer: A

Rationale: The correct answer is A: Hyperkalemia. In CKD, the kidneys are unable to effectively excrete potassium, leading to its accumulation in the blood. This can result in dangerous cardiac complications. Hyperkalemia is a common and critical complication in CKD patients. B: Hypokalemia is unlikely in CKD as the kidneys typically retain potassium. C: Hyperglycemia is more commonly associated with diabetes rather than CKD. D: Hypercalcemia is not a common complication of CKD; in fact, CKD often leads to lower calcium levels due to impaired activation of vitamin D.

Correct Answer: A

Rationale: The correct answer is A: Administer warm IV fluids. This is because in severe hypothermia, the body's core temperature drops dangerously low, leading to decreased circulation and potential organ failure. Administering warm IV fluids helps to gradually raise the core temperature and prevent further complications. Choice B (Warming the client with a heating pad) can cause rewarming shock and skin burns. Choice C (Placing the client in a supine position) is not directly related to treating hypothermia. Choice D (Administering analgesics) is not the priority in treating severe hypothermia.
