Question 1 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 2 of 5
MIMS stands for:
Correct Answer: C
Rationale: MIMS stands for Monthly Index of Medical Specialties. It is a comprehensive drug database and medical reference resource widely used by healthcare professionals around the world. MIMS provides essential information on prescription and over-the-counter drugs, medical news, disease management guidelines, medical directories, and more. The term "Monthly" in MIMS highlights that the information is regularly updated on a monthly basis to ensure healthcare professionals have access to the most current and reliable information relevant to their practice.
Question 3 of 5
The process by which a gas is released in a certain substance when added with water
Correct Answer: A
Rationale: The term "effervescent" refers to the process of a gas being released from a substance when added to water. This is commonly observed when certain tablets or powders are added to water, resulting in the production of bubbles or fizz. Mucilage refers to a thick, sticky substance, while spirits typically refer to alcoholic beverages. Collyria are eye drops, and collodion is a solution used in photography and medicine. Therefore, the correct term for the described process is "effervescent."
Question 4 of 5
The primary beneficial action of epinephrine when performing root end surgery is which of the following?
Correct Answer: C
Rationale: Epinephrine primarily acts on beta1 adrenergic receptors in the alveolar mucosa during root end surgery. This results in vasoconstriction, which reduces bleeding in the surgical field by constricting blood vessels. With decreased bleeding, the surgical site becomes clearer, allowing for better visualization and manipulation during the procedure. Additionally, epinephrine may also prolong the duration of anesthesia by reducing systemic uptake of the local anesthetic solution, thus enhancing its effect locally.
Question 5 of 5
A patient is scheduled to receive high-dose cyclophosphamide via an intravenous infusion as treatment for cancer. Which will be most important for the nurse to include when teaching the patient about cyclophosphamide?
Correct Answer: B
Rationale: Cyclophosphamide can cause hemorrhagic cystitis, a serious side effect resulting from the irritation of the bladder lining by its metabolites. To prevent this, patients must maintain high fluid intake (at least 2 liters per day) to dilute the urine and flush out the bladder. While emptying the bladder regularly is important, it is secondary to ensuring adequate hydration. Limiting fluid intake is contraindicated, as it increases the risk of bladder toxicity. An indwelling urinary catheter is not routinely required unless the patient has urinary retention.
