Correct Answer: A

Rationale: The correct answer is A: Hypocalcemia. Chvostek's sign and Trousseau's sign are both indicators of hypocalcemia, which is a common complication following thyroidectomy surgery due to potential damage to the parathyroid glands. Chvostek's sign is elicited by tapping the facial nerve and observing facial muscle twitching, while Trousseau's sign involves carpal spasm induced by inflating a blood pressure cuff above systolic pressure. Both signs are sensitive indicators of hypocalcemia due to their association with neuromuscular irritability. Hypercalcemia (option C) and hyperkalemia (option D) are not typically associated with thyroidectomy surgery and would not present with these specific signs. Hypokalemia (option B) is not related to Chvostek's sign and Trousseau's sign.

Correct Answer: A

Rationale: The correct answer is A: Include dressing change instructions and frequency in the care plan. This is the correct action because it ensures consistency in care and communication among the nursing team. By documenting the dressing change instructions and frequency in the care plan, all nurses will have clear guidance on how to perform the dressing changes correctly and at the appropriate intervals. This promotes continuity of care and helps prevent errors or omissions in the dressing change process. Option B is incorrect as it is not realistic to expect the wound nurse to perform all dressing changes. Option C is unnecessary unless there are specific concerns requiring the health care provider's attention. Option D is not appropriate as encouraging the patient to perform dressing changes may not be safe or feasible depending on the patient's condition.

Correct Answer: D

Rationale: The correct answer is D because airborne pollens and molds are common triggers for allergic rhinitis. Understanding these triggers helps in avoiding exposure and managing symptoms. Choices A, B, and C are incorrect as they do not specifically relate to allergic rhinitis triggers, focusing instead on other forms of medication or topical applications. By understanding airborne triggers, the patient can take appropriate preventive measures.

Correct Answer: A

Rationale: The correct answer is A: White patches on the tonsils. Group A streptococci infection commonly presents with exudative tonsillitis, characterized by the presence of white patches or pus on the tonsils. This is due to the inflammatory response triggered by the bacteria. Hypertrophied tonsils (B), hemorrhage in the tonsils (C), and bleeding in the tonsils (D) are less likely to be visual signs of a streptococcal infection and are more indicative of other conditions or complications. Therefore, white patches on the tonsils are the most specific visual sign associated with group A streptococci tonsillar infection.

Correct Answer: C

Rationale: The correct answer is C: "You may feel a burning sensation when the dye is injected." This is important preprocedure teaching for carotid angiography because it prepares the patient for a common sensation during the procedure, helping to manage their expectations and reduce anxiety. This information is crucial for informed consent. Choice A is incorrect because carotid angiography is usually done under local anesthesia, not general anesthesia. Choice B is incorrect as carotid angiography typically takes about 1-2 hours, not several hours. Choice D is incorrect because all medical procedures, including carotid angiography, carry potential risks and complications, which should be discussed with the patient.
