Correct Answer: B

Rationale: Correct! In right-sided congestive heart failure, jugular vein distention is a common finding due to the backup of blood in the systemic circulation. This results in increased venous pressure, leading to jugular vein distention. Choices A, C, and D are incorrect because decreased urinary output, pleural effusion, and bibasilar crackles are more commonly associated with other conditions such as kidney dysfunction, lung issues, and pulmonary edema.

Correct Answer: A

Rationale: An allergy to shellfish often indicates an allergy to iodine, which is used in contrast dyes for CT scans. This poses a significant risk of an allergic reaction during the procedure. The nurse must ensure appropriate precautions or alternative imaging are considered. Choices B, C, and D are not directly contraindicated for a CT scan with contrast. Smoking history, metformin use, and controlled hypertension do not typically impact the safety or feasibility of the procedure.

Correct Answer: C

Rationale: The correct answer is C: Bananas. Bananas are high in potassium and should be avoided in clients who are on a low-potassium diet due to chronic kidney disease. Foods like apples and white bread are low in potassium and are safer choices. Carrots are also low in potassium and do not need to be avoided in this case.

Correct Answer: A

Rationale: Weight-bearing exercises are crucial in managing osteoporosis as they help strengthen bones. Choice A is the correct answer because weight-bearing activities, such as walking, dancing, or weight training, help stimulate bone formation and strengthen bones, which is essential in managing osteoporosis. Choice B is incorrect as the primary focus should be on the type of exercise rather than weight reduction. Choice C is incorrect because avoiding exercise altogether can lead to further bone density loss, and it is important to engage in safe weight-bearing activities. Choice D is incorrect as the primary goal of exercise in osteoporosis is to improve bone density through weight-bearing activities.

Correct Answer: A

Rationale: The correct answer is to administer a dose of hydrocortisone immediately. In Addison's disease, confusion and weakness can be signs of an adrenal crisis. Administering hydrocortisone promptly is crucial to prevent further deterioration. Checking electrolyte levels (Choice B) is important but not the first action in managing an acute adrenal crisis. Administering normal saline (Choice C) is not the priority in this situation. Measuring blood pressure in both arms (Choice D) is not the initial action needed to address the client's confusion and weakness in Addison's disease.
