Correct Answer: D

Rationale: The correct answer is D: 'I should report any chest pain during the test.' This statement indicates an understanding of the teaching because reporting chest pain during an exercise stress test is crucial as it may signify cardiac distress. Choices A, B, and C are incorrect. Eating a large meal 2 hours before the test is not recommended as it may affect the results. Avoiding drinking water before the test is also not advisable as staying hydrated is important. Stopping blood pressure medication without medical advice can be dangerous, especially before a stress test.

Correct Answer: A

Rationale: The correct answer is A: 'Heart disease and stroke.' Untreated hypertension can lead to various complications, including heart disease and stroke. These are common outcomes of long-term high blood pressure. Choice B, 'Kidney failure and vision loss,' is incorrect as kidney failure and vision loss are more commonly associated with diabetic complications rather than untreated hypertension. Choice C, 'Pulmonary embolism and arrhythmias,' while serious, are not among the primary complications of untreated hypertension. Choice D, 'Blood clots and gastrointestinal bleeding,' are not typical complications of untreated hypertension but can occur due to other conditions such as blood clotting disorders or gastrointestinal diseases.

Correct Answer: B

Rationale: Tingling in the fingers is a classic sign of hypocalcemia. Following a thyroidectomy, hypocalcemia can occur due to damage to the parathyroid glands, which regulate calcium levels in the body. Nausea, numbness in the toes, and sweating are not specific signs of hypocalcemia. Numbness and tingling usually start in the hands and feet due to their increased nerve sensitivity to low calcium levels.

Correct Answer: B

Rationale: To prevent dislocation of the prosthesis after hip replacement surgery, it is essential to avoid bending the hip more than 90 degrees. This precaution helps maintain the stability of the hip joint and reduces the risk of prosthesis dislocation. Crossing legs at the knees (Choice A) can increase pressure on the hip joint, leading to instability. Sitting with legs elevated (Choice C) and avoiding placing a pillow under the knees (Choice D) do not directly address the risk of prosthesis dislocation.

Correct Answer: B

Rationale: Tingling and numbness in the hands can indicate hypocalcemia, a common complication following a thyroidectomy. Hypocalcemia requires immediate intervention to prevent severe complications like tetany and seizures. Calcium gluconate is the drug of choice for rapidly raising serum calcium levels in hypocalcemic patients. Sodium bicarbonate is not indicated for treating hypocalcemia or related symptoms. Potassium chloride is used to correct potassium imbalances, not calcium. Magnesium sulfate is not the appropriate treatment for hypocalcemia; it is commonly used for conditions like preeclampsia or eclampsia.
