Question 1 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 2 of 5
Which of the following diuretics inhibits sodium reabsorption in the kidneys while saving K+ and Hydrogen ions?
Correct Answer: A
Rationale: Spironolactone is a potassium-sparing diuretic, which belongs to the aldosterone receptor antagonists. It works by inhibiting aldosterone activity in the distal convoluted tubule and collecting ducts of the kidney. Aldosterone promotes sodium reabsorption in exchange for potassium and hydrogen ions. By blocking aldosterone, Spironolactone allows for increased excretion of sodium while retaining potassium and hydrogen ions, making it a suitable choice for patients who need to maintain potassium levels or are at risk for hypokalemia.
Question 3 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 4 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.
Question 5 of 5
The patient is discharged home and returns to the emergency department 4 days later. The patient is admitted to the ICU with acute decompensated HF with dyspnea at rest. The nurse anticipates administration of which medication?
Correct Answer: D
Rationale: Nesiritide, also known as Natrecor, is a medication commonly used in the treatment of acute decompensated heart failure (ADHF) with dyspnea at rest. It is a recombinant form of B-type natriuretic peptide (BNP) which helps to improve cardiac function and alleviate symptoms of heart failure, such as dyspnea. Nesiritide works by promoting vasodilation and increasing diuresis, which can help reduce the workload on the heart and improve cardiac output.
Therefore, in the case of a patient with acute decompensated heart failure and dyspnea at rest, the nurse would anticipate the administration of Nesiritide to help improve the patient's condition.
