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
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 3 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.
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
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.
