Question 1 of 5
Which of the following is NOT an opioid or NSAID?
Correct Answer: D
Rationale: Acetaminophen is not an opioid or NSAID. While it is commonly used to relieve pain and reduce fever, acetaminophen works differently from opioids and NSAIDs. Acetaminophen is believed to reduce pain by inhibiting the production of prostaglandins in the brain, whereas opioids work by binding to opioid receptors in the central nervous system, and NSAIDs work by inhibiting the production of prostaglandins in the peripheral tissues.
Question 2 of 5
The following are examples of prodrugs:
Correct Answer: D
Rationale: All these drugs require metabolic activation to exert their therapeutic effects, making them prodrugs.
Question 3 of 5
Antifibrinolytic drugs:
Correct Answer: A
Rationale: Antifibrinolytic drugs work by inhibiting the activity of plasmin, an enzyme responsible for the breakdown of fibrin clots. By blocking the activation of plasminogen to form plasmin, these drugs help stabilize the formed fibrin clot, thus promoting hemostasis and preventing excessive bleeding. This mechanism is particularly useful in conditions where increased fibrinolysis is a concern, such as in surgical procedures or certain bleeding disorders. Examples of antifibrinolytic drugs include tranexamic acid and aminocaproic acid.
Question 4 of 5
A client calls the clinic and tells the nurse that she has missed taking several of her contraceptive pills during the current cycle. What is the best instruction for the nurse to give the client?
Correct Answer: D
Rationale: Missing oral contraceptive pills reduces their efficacy, increasing pregnancy risk. If several pills are missed , the hormonal protection is compromised, requiring an alternative method (e.g., condoms) for the cycle's remainder to prevent conception. Immediate pregnancy testing assesses outcome, not prevention. Suggesting a new method addresses future planning, not current risk. Choice C underestimates the risk, as even fewer than three missed pills can disrupt efficacy, depending on timing. The nurse's best instruction (D) ensures immediate protection, aligning with contraceptive guidelines for missed doses, prioritizing safety and efficacy.
Question 5 of 5
What is the therapeutic use of metformin?
Correct Answer: D
Rationale: Metformin is a medication commonly used to treat type 2 diabetes by helping to control high blood sugar levels. It works by decreasing the amount of sugar produced by the liver and increasing the body's response to insulin. By aiding in controlling blood glucose levels, metformin helps prevent complications of diabetes such as kidney damage, blindness, nerve problems, and loss of limbs. It does not lower blood pressure, diminish seizure activity, increase heart rate, or decrease gastrointestinal secretions.
