  • 2. 

    Which change in vital signs would you instruct a nursing assistant to report immediately for a patient with hyperthyroidism?  

    • A.

      Increased and rapid heart rate

    • B.

      Decrease systolic blood pressure

    • C.

      Increased respiratory rate

    • D.

      Decreased oral temperature

    Correct Answer
    A. Increased and rapid heart rate
    Explanation
    The cardiac problems associated with hyperthyroidism include tachycardia, increased systolic blood pressure, and decreased diastolic blood pressure. Patients with hyperthyroidism also may have increased body temperature related to increased metabolic rate. Focus: Delegation/supervision

    Rate this question:

  • 3. 

    For the patient with hyperthyroidism, what intervention should you delegate to the experienced certified nursing assistant?    

    • A.

      Instruct the patient to report palpitations, dyspnea, vertigo, pr chest pain.

    • B.

      Check the apical pulse, blood pressure, and temperature every 4 hours.

    • C.

      Draw blood for thyroid-stimulating hormone, T3, and T4 levels.

    • D.

      Explain the side effects of propylthiouracil (PTU) to the patient.

    Correct Answer
    B. Check the apical pulse, blood pressure, and temperature every 4 hours.
    Explanation
    Monitoring and recording vital signs are within the education scope of nursing assistants. An experienced nursing assistant should have been taught how to monitor the apical pulse. However, the nurse should observe the nursing assistant to be sure that she has mastered this skill. Instructing and teaching patients, as well as performing venipuncture for laboratory samples, are more suited to the educational scope of licensed nurses. In some facilities, an experienced nursing assistant may perform venipuncture, but only after special training. Focus: Delegation/supervision

    Rate this question:

  • 5. 

    Which nursing diagnosis takes highest priority for a female client with hyperthyroidism?

    • A.

      Risk for imbalanced nutrition: More than body requirements related to thyroid hormone excess

    • B.

      Risk for impaired skin integrity related to edema, skin fragility, and poor wound healing

    • C.

      Body image disturbance related to weight gain and edema

    • D.

      Imbalanced nutrition: Less than body requirements related to thyroid hormone excess

    Correct Answer
    D. Imbalanced nutrition: Less than body requirements related to thyroid hormone excess
    Explanation
    In the client with hyperthyroidism, excessive thyroid hormone production leads to hypermetabolism and increased nutrient metabolism. These conditions may result in a negative nitrogen balance, increased protein synthesis and breakdown, decreased glucose tolerance, and fat mobilization and depletion. This puts the client at risk for marked nutrient and calorie deficiency, making Imbalanced nutrition: Less than body requirements the most important nursing diagnosis.

  • 6. 

    Matilda, with hyperthyroidism is to receive Lugol’s iodine solution before a subtotal thyroidectomy is performed. The nurse is aware that this medication is given to:    

    • A.

      Decrease the total basal metabolic rate.

    • B.

      Maintain the function of the parathyroid glands.

    • C.

      Block the formation of thyroxine by the thyroid gland.

    • D.

      Decrease the size and vascularity of the thyroid gland.

    Correct Answer
    D. Decrease the size and vascularity of the thyroid gland.
    Explanation
    Lugol’s solution provides iodine, which aids in decreasing the vascularity of the thyroid gland, which limits the risk of hemorrhage when surgery is performed.

  • 7. 

     The physician orders laboratory tests to confirm hyperthyroidism in a female client with classic signs and symptoms of this disorder. Which test result would confirm the diagnosis?

    • A.

      No increase in the thyroid-stimulating hormone (TSH) level after 30 minutes during the TSH stimulation test

    • B.

      A decreased TSH level

    • C.

      An increase in the TSH level after 30 minutes during the TSH stimulation test

    • D.

      Below-normal levels of serum triiodothyronine (T3) and serum thyroxine (T4) as detected by radioimmunoassay

    Correct Answer
    A. No increase in the thyroid-stimulating hormone (TSH) level after 30 minutes during the TSH stimulation test
    Explanation
    In the TSH test, failure of the TSH level to rise after 30 minutes confirms hyperthyroidism. A decreased TSH level indicates a pituitary deficiency of this hormone. Below-normal levels of T3 and T4, as detected by radioimmunoassay, signal hypothyroidism. A below-normal T4 level also occurs in malnutrition and liver disease and may result from administration of phenytoin and certain other drugs.

    Ms.Clark has hyperthyroidism and is scheduled for a thyroidectomy. The physician has ordered Lugol’s solution for the client. The nurse understands that the primary reason for giving Lugol’s solution preoperatively is to:

    • A.

      Decrease the risk of agranulocytosis postoperatively.

    • B.

      Prevent tetany while the client is under general anesthesia.

    • C.

      Reduce the size and vascularity of the thyroid and prevent hemorrhage.

    • D.

      Potentiate the effect of the other preoperative medication so less medicine can be given while the client is under anesthesia.

    Correct Answer
    C. Reduce the size and vascularity of the thyroid and prevent hemorrhage.
    Explanation
    Doses of over 30 mg/day may increase the risk of agranulocytosis. Lugol’s solution does not act to prevent tetany. Calcium is used to treat tetany. The client may receive iodine solution (Lugol’s solution) for 10 to 14 days before surgery to decrease vascularity of the thyroid and thus prevent excess bleeding. Lugol’s solution does not potentiate any other preoperative medication.

    • D.

      Imbalanced nutrition: Less than body requirements related to thyroid hormone excess

    Correct Answer
    D. Imbalanced nutrition: Less than body requirements related to thyroid hormone excess
    Explanation
    In the client with hyperthyroidism, excessive thyroid hormone production leads to hypermetabolism and increased nutrient metabolism. These conditions may result in a negative nitrogen balance, increased protein synthesis and breakdown, decreased glucose tolerance, and fat mobilization and depletion. This puts the client at risk for marked nutrient and calorie deficiency, making Imbalanced nutrition: Less than body requirements the most important nursing diagnosis.

    What are the functions of T3 and T4?

    • A.

      Retention of salt and water

    • B.

      Maintenance of blood sugar

    • C.

      Maintenance of blood pressure

    • D.

      Regulation of energy production

    Correct Answer
    D. Regulation of energy production
    Explanation
    T3 and T4, also known as thyroid hormones, play a crucial role in regulating energy production in the body. These hormones are responsible for controlling the metabolism of cells, which affects how the body uses energy. They stimulate the production of ATP, the energy currency of cells, and regulate the breakdown of fats, proteins, and carbohydrates to provide energy. Therefore, the correct answer is "Regulation of energy production."

    Which of the following nursing assessment is the most important in the patient with hyperthyroidism and risk for thyrotoxic crisis or thyroid storm?

    • A.

      Intake and output

    • B.

      Heart sounds

    • C.

      Bowel sounds

    • D.

      Vital signs

    Correct Answer
    D. Vital signs
    Explanation
    In a patient with hyperthyroidism and risk for thyrotoxic crisis or thyroid storm, monitoring vital signs is the most important nursing assessment. Vital signs such as heart rate, blood pressure, respiratory rate, and temperature can provide crucial information about the patient's cardiovascular and metabolic status. Hyperthyroidism can cause an increase in heart rate and blood pressure, and monitoring these vital signs can help detect any abnormalities or signs of worsening thyrotoxic crisis. Assessing vital signs regularly allows for early identification and prompt intervention in case of any deterioration in the patient's condition.

    Rate this question:

  • 15. 

    Which medication will the nurse have available for emergency treatment of tetany in the client who has had thyroidectomy?

    • A.

      Calcium chloride

    • B.

      Potassium chloride

    • C.

      Magnesium chloride

    • D.

      Sodium bicarbonate

    Correct Answer
    B. Potassium chloride
    Explanation
    Potassium chloride is not the correct medication for emergency treatment of tetany in a client who has had a thyroidectomy. Tetany is a condition characterized by muscle spasms and twitching, often caused by low levels of calcium in the blood. The correct medication for emergency treatment of tetany is calcium chloride, as it helps to increase calcium levels in the blood and alleviate the symptoms of tetany. Potassium chloride is used to treat potassium deficiencies and is not effective in treating tetany.
