Correct Answer: B

Rationale: The correct answer is B, Chvostek's sign. This is a classic sign of hypocalcemia, which can occur after a thyroidectomy due to injury or removal of the parathyroid glands. Hypocalcemia can lead to serious complications like tetany and laryngospasm, necessitating immediate attention. Assessing Chvostek's sign helps in early identification and management of hypocalcemia. Choices A, C, and D are not the priority in this situation. While assessing the calcium level is important for diagnosing hypocalcemia, the immediate concern is to identify clinical signs like Chvostek's sign, which indicate acute hypocalcemia. Trousseau's sign is also related to hypocalcemia but is not the most critical sign to assess first. Serum potassium level, although important for overall electrolyte balance, is not directly related to the client's current symptoms of tingling in the fingers and around the mouth.

Correct Answer: B

Rationale: The observation of the client's entire body turning a bright red color during an excretory urogram indicates a severe reaction to the dye, which is a significant complication. This reaction is likely due to an allergic response and requires immediate medical attention. The other choices do not signify a severe complication: choice A could be a normal taste sensation related to the procedure, choice C may indicate a mild reaction, and choice D could be a common side effect of nausea without indicating a severe complication requiring immediate intervention.

Correct Answer: A

Rationale: The correct answer is A. Increasing caloric intake by eating foods high in protein can help Crohn's Disease patients maintain their weight and manage symptoms. Choice B is incorrect because fresh fruits and vegetables may exacerbate symptoms due to their high fiber content. Choice C is incorrect as high-fat foods can be difficult to digest and may worsen symptoms. Choice D is incorrect because whole milk can be problematic for individuals with Crohn's Disease due to its high fat content.

Correct Answer: C

Rationale: Black, tarry stools can indicate gastrointestinal bleeding, which is a serious complication of peptic ulcer disease. This finding suggests active bleeding in the gastrointestinal tract, requiring immediate attention. A normal heart rate of 72 beats per minute (choice A) is within the expected range. A hemoglobin level of 12 g/dL (choice B) is also within normal limits. Nausea and vomiting (choice D) are common symptoms associated with peptic ulcer disease but may not necessarily indicate active bleeding like black, tarry stools.

Correct Answer: B

Rationale: In this scenario, the nurse should administer acetaminophen as ordered because a slight fever is normal after an MI. This intervention can help manage the fever unless other complications are present. Calling the health care provider immediately is not necessary for a slight fever post-MI. Sending blood, urine, and sputum for culture is not indicated solely based on a slight fever without other symptoms or signs of infection. Increasing fluid intake may be beneficial for various reasons but is not the priority in this situation where managing the fever with acetaminophen is appropriate.
