A nurse is assessing a client who has Graves’ disease. The nurse should expect which of the following laboratory results?
Decreased thyroxine (T4) level.
Decreased triiodothyronine (T3) level.
Decreased thyroid-stimulating immunoglobulins (TSI) percentage.
Decreased thyroid-stimulating hormone (TSH) level.
The Correct Answer is D
Choice A Reason:
A decreased thyroxine (T4) level is not expected in a client with Graves’ disease. Graves’ disease is an autoimmune disorder that leads to hyperthyroidism, where the thyroid gland produces excessive amounts of thyroid hormones, including T4. Therefore, the T4 level is typically elevated, not decreased.
Choice B Reason:
Similarly, a decreased triiodothyronine (T3) level is not expected in Graves’ disease. Like T4, T3 levels are usually elevated due to the overactive thyroid gland. T3 is the active form of thyroid hormone and is often increased in hyperthyroid conditions.
Choice C Reason:
Decreased thyroid-stimulating immunoglobulins (TSI) percentage is incorrect. In Graves’ disease, TSI levels are elevated because these antibodies stimulate the thyroid gland to produce more thyroid hormones. TSI mimics the action of TSH, leading to increased production of T3 and T4.
Choice D Reason:
Decreased thyroid-stimulating hormone (TSH) level is the correct answer. In Graves’ disease, the excessive thyroid hormones (T3 and T4) exert negative feedback on the pituitary gland, leading to suppressed TSH production. Therefore, TSH levels are typically low in patients with Graves’ disease.

Correct Answer is ["B"]
Explanation
The correct answer is
a. Increased respiratory rate
b. Increased heart rate
c. Increased blood pressure
Choice A: Increased Respiratory Rate
Fluid overload, also known as hypervolemia, can lead to an increased respiratory rate. This occurs because the excess fluid in the body can accumulate in the lungs, leading to pulmonary congestion and edema. As a result, the body attempts to compensate by increasing the respiratory rate to improve oxygenation and remove excess carbon dioxide. Normal respiratory rate for adults is typically between 12-20 breaths per minute. An increased respiratory rate above this range can indicate fluid overload.
Choice B: Increased Heart Rate
An increased heart rate, or tachycardia, is another common finding in clients with fluid overload. The heart has to work harder to pump the excess fluid throughout the body, leading to an increased heart rate. This is a compensatory mechanism to maintain adequate cardiac output and tissue perfusion. Normal resting heart rate for adults is between 60-100 beats per minute. A heart rate above this range can be indicative of fluid overload.
Choice C: Increased Blood Pressure
Fluid overload can also result in increased blood pressure, or hypertension. The excess fluid in the bloodstream increases the volume of blood that the heart has to pump, leading to higher pressure within the arteries. This can strain the cardiovascular system and lead to complications if not managed properly. Normal blood pressure is typically around 120/80 mmHg. Blood pressure readings consistently above this range can suggest fluid overload.
Choice D: Increased Hematocrit
Increased hematocrit is not typically associated with fluid overload. Hematocrit is the proportion of red blood cells in the blood. In cases of fluid overload, the hematocrit level is usually decreased due to the dilutional effect of the excess fluid. Therefore, this choice is incorrect.
Choice E: Increased Temperature
Increased temperature is not a common finding in fluid overload. Fever or elevated body temperature is more commonly associated with infections or inflammatory conditions. Fluid overload does not typically cause an increase in body temperature. Therefore, this choice is incorrect.
Correct Answer is B
Explanation
Choice A reason:
Elevating the head of the client’s bed can help reduce blood pressure slightly by promoting venous return and decreasing intracranial pressure. However, this action alone is not sufficient to address the severe hypertension (254/139 mm Hg) the client is experiencing. Immediate medical intervention is required to prevent complications such as stroke, heart attack, or organ damage.
Choice B reason:
Contacting the Rapid Response Team is the highest priority action. The Rapid Response Team is trained to handle critical situations and can provide immediate interventions to stabilize the client’s condition. Severe hypertension at this level requires urgent medical attention to prevent life-threatening complications. The team can administer medications to lower blood pressure quickly and monitor the client closely.
Choice C reason:
Telling the client to report vision changes is important because vision changes can indicate hypertensive retinopathy or increased intracranial pressure. However, this action is not the immediate priority. The client’s blood pressure needs to be controlled urgently to prevent further complications.
Choice D reason:
Inserting a peripheral IV is necessary for administering medications and fluids. While this is an important step, it should follow the immediate action of contacting the Rapid Response Team. The team can then use the IV access to administer antihypertensive medications promptly.
Choice E reason:
Initiating seizure precautions is important because severe hypertension can lead to seizures. However, this action is not the first priority. The primary focus should be on stabilizing the client’s blood pressure through immediate medical intervention.
