Question 1 of 5
Who is the primary authority source for drug standards in the United States?
Correct Answer: B
Rationale: The correct answer is B: Food and Drug Administration (FD
A). The FDA is responsible for regulating and overseeing the standards for drug safety, efficacy, and quality in the United States. They review and approve new drugs before they can be marketed, set guidelines for manufacturing practices, and monitor drug safety post-market. The DEA (
A) focuses on enforcing controlled substance laws, CDC (
C) focuses on public health, and NIH (
D) is primarily a research agency.
Choices E, F, and G are irrelevant and do not pertain to drug standards.
Question 2 of 5
A nurse caring for a client who has a new prescription for atenolol. For which of the following adverse effects should the nurse monitor the client?
Correct Answer: B
Rationale: The correct answer is B: Bradycardia. Atenolol is a beta-blocker that can cause bradycardia due to its effect on reducing heart rate. The nurse should monitor the client for signs of bradycardia such as dizziness, fatigue, and low heart rate. Neutropenia (
A), anemia (
C), and hypokalemia (
D) are not common adverse effects of atenolol. Neutropenia is more commonly associated with other medications like chemotherapy, anemia is not a known side effect of atenolol, and hypokalemia is more associated with diuretics.
Question 3 of 5
Which drug group inhibits the formation of clots?
Correct Answer: D
Rationale: The correct answer is D: Anticoagulants. Anticoagulants are drugs that specifically target and inhibit the formation of blood clots by interfering with the clotting cascade. They work by blocking certain clotting factors or enzymes involved in the clotting process. Antibiotics (
A), analgesics (
B), and antidepressants (
C) do not have any direct effect on clot formation. Antibiotics are used to treat bacterial infections, analgesics are pain relievers, and antidepressants are used to treat depression. Anticoagulants are the only drug group among the choices that directly target clot formation, making them the correct answer.
Question 4 of 5
A nurse is preparing to administer 0/9% sodium chloride (0.9% NaCl) 20ml/kg IV tp infuse over 6 hr to a school-age child who weighs 55 lbs. The nurse should set the IV pump to deliver how many ml/hr? (Round to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: D
Rationale:
To calculate the IV rate, first convert the child's weight from pounds to kg: 55 lbs ÷ 2.2 = 25 kg.
Then, calculate the total fluid volume needed: 20 ml/kg x 25 kg = 500 ml. Next, determine the infusion time in hours: 6 hours. Finally, divide the total volume by the infusion time to get the rate: 500 ml ÷ 6 hr ≈ 83 ml/hr.
Therefore, the correct answer is D (83 mL/hr) because it accurately calculates the infusion rate based on the child's weight and the desired infusion time. Other choices are incorrect as they don't follow the correct calculation method or provide inaccurate results.
Question 5 of 5
Which of the following is stated correctly using metric abbreviations and rules?
Correct Answer: A
Rationale: The correct answer is A: Ampicillin 500 mg. This is the correct format following metric abbreviations and rules. In the metric system, lowercase letters are used for units, and uppercase letters are used for prefixes. The value (500) comes before the unit (mg), and there should be a space between the number and the unit.
Choice B has the incorrect order of value and unit.
Choice C uses uppercase letters for the unit, which is incorrect.
Choice D is not necessary to include the decimal point and zero for whole numbers.
