Question 2 of 5
What is the therapeutic use of levothyroxine?
Correct Answer: C
Rationale: Levothyroxine is a synthetic form of the thyroid hormone thyroxine (T4). It is primarily used for the treatment of hypothyroidism, a condition in which the thyroid gland does not produce enough thyroid hormone. By providing exogenous levothyroxine, the medication helps to restore the normal hormonal balance in the body. This can alleviate symptoms such as fatigue, weight gain, cold intolerance, and other issues related to an underactive thyroid gland. Levothyroxine is not used for the suppression of seizure activity, decreased frequency of migraines, or treatment of ulcers.
Question 3 of 5
For the patient receiving periodic morphine via intravenous push, which of the following findings would be of utmost concern to the nurse?
Correct Answer: C
Rationale: Morphine is an opioid analgesic that can cause respiratory depression as a serious side effect. Decreased respirations are a critical finding because they indicate that the patient may not be receiving adequate oxygenation, which can lead to hypoxia, brain damage, or even death. Increased temperature, decreased bowel sounds, and increased red blood cell count are less concerning in this context. Nurses must monitor respiratory rates closely in patients receiving morphine and be prepared to intervene with naloxone if respiratory depression occurs.
Question 4 of 5
The nurse receives a stat order to administer 50% dextrose solution intravenously to a 1-year-old child with hypoglycemia. How should this drug best be prepared for safe administration to the child?
Correct Answer: C
Rationale: Administering 50% dextrose solution directly to a 1-year-old child is unsafe due to the risk of hyperosmolar injury to veins and tissues. Diluting it 1:1 with sterile water reduces the concentration to 25%, making it safer for pediatric administration. Using a filter needle (A) or tuberculin syringe (B) is not necessary for this preparation. Shaking the solution (D) is inappropriate and could introduce air bubbles.
Question 5 of 5
What is the therapeutic use of levothyroxine?
Correct Answer: C
Rationale: Levothyroxine is a synthetic form of the thyroid hormone thyroxine and is commonly used for the treatment of hypothyroidism. Hypothyroidism is a condition where the thyroid gland does not produce enough thyroid hormone to meet the body's needs, leading to various symptoms such as fatigue, weight gain, cold intolerance, and depression. By providing exogenous levothyroxine, the medication helps restore normal thyroid hormone levels in the body, thereby alleviating the symptoms of hypothyroidism and restoring normal hormonal balance. It is important to monitor thyroid hormone levels regularly when on levothyroxine therapy to ensure optimal dosing and maintenance of normal thyroid function.
