Correct Answer: B

Rationale: Tingling in the lips and fingers is a classic sign of hypocalcemia, which can occur as a complication following a thyroidectomy due to inadvertent damage to the parathyroid glands that regulate calcium levels. Hypokalemia (
Choice
A) presents with muscle weakness and cardiac issues, not tingling. Hyponatremia (
Choice
C) typically manifests with confusion, seizures, and muscle cramps. Hyperglycemia (
Choice
D) is associated with increased thirst, frequent urination, and fatigue.

Correct Answer: D

Rationale: The correct answer is D, INR. The International Normalized Ratio (INR) is used to monitor the therapeutic effect of warfarin and to adjust the dose as needed. While Prothrombin time (PT) and activated Partial Thromboplastin Time (aPTT) are also related to coagulation studies, monitoring INR specifically helps in managing warfarin therapy. Hemoglobin, on the other hand, is not typically monitored in relation to warfarin therapy.

Correct Answer: C

Rationale: The correct answer is C. A heart rate of 110/min is elevated and may indicate hypocalcemia, a potential complication following a thyroidectomy. Elevated heart rate can be a sign of hypocalcemia due to the close relationship between calcium levels and cardiac function. Option A, serum calcium level of 8 mg/dL, is within the normal range (8.5-10.5 mg/dL) and would not be a cause for concern post-thyroidectomy. Option B, urine output of 60 mL/hr, is within the normal range for urine output and not typically a priority finding post-thyroidectomy. Option D, a temperature of 37.5°C (99.5°F), is slightly elevated but not a critical finding post-thyroidectomy unless accompanied by other symptoms.

Correct Answer: D

Rationale: The correct answer is D: Tachycardia. In clients with hyperthyroidism, tachycardia is a common finding due to the increased metabolic rate. Weight loss and heat intolerance are also expected due to the elevated metabolism.

Choices A, B, and C (Weight gain, dry skin, cold intolerance) are not typical findings in hyperthyroidism, as the condition is associated with an overactive thyroid gland leading to an increase in metabolic functions.

Correct Answer: D

Rationale: The correct answer is D: Elevated temperature. Cocaine is a stimulant drug that can lead to increased body temperature. Hypotension (
Choice
A) is less likely as cocaine tends to elevate blood pressure. Memory loss (
Choice
B) and slurred speech (
Choice
C) are more commonly associated with depressant drugs rather than stimulant drugs like cocaine.
