ATI RN Fundamental Proctored Exam With NGN Graded Questions
Extract:
Question 1 of 5
A nurse is reviewing the reported medications of a client who was recently admitted. The medications include cimetidine (Tagamet) and imipramine hydrochloride (Tofranil). Knowing that cimetidine decreases the metabolism of imipramine hydrochloride, the nurse should identify that this combination is likely to result in which of the following effects?
Correct Answer: B
Rationale: The correct answer is B: Increased risk of imipramine hydrochloride toxicity. Cimetidine inhibits the metabolism of imipramine hydrochloride, leading to increased levels of imipramine in the body. This can result in a higher concentration of imipramine, potentially causing toxicity. This interaction is known as a pharmacokinetic drug-drug interaction.
Incorrect choices:
A: Decreased therapeutic effects of cimetidine - This is incorrect because cimetidine's therapeutic effects are not directly impacted by its interaction with imipramine.
C: Decreased risk of adverse effects of cimetidine - This is incorrect as there is no evidence to suggest that the interaction with imipramine decreases the risk of adverse effects of cimetidine.
D: Increased therapeutic effects of imipramine hydrochloride - This is incorrect as the increased risk of toxicity does not equate to increased therapeutic effects.
Question 2 of 5
A nurse in an outpatient clinic is caring for a client who states she is trying to get pregnant. The client currently takes a Category D pregnancy risk medication for the control of seizures. Which of the following statements by the nurse is appropriate?
Correct Answer: A
Rationale: The correct answer is A. Category D medications have shown evidence of risk to the fetus in human studies but potential benefits may outweigh risks in certain situations. The nurse should inform the client about the risks and benefits of continuing the medication while trying to conceive.
Choice B is incorrect because Category D medications are not considered safe during pregnancy.
Choice C is incorrect as it is not entirely true that the risk always outweighs the benefits.
Choice D is incorrect because assuming safety without evidence is risky. The nurse should provide accurate information to guide the client's decision-making.
Question 3 of 5
A nurse in an outpatient surgical center is admitting a client for a laparoscopic procedure. The client has a prescription for preoperative diazepam (Valium). Prior to administering the medication, which of the following actions is the highest priority?
Correct Answer: C
Rationale: The highest priority action before administering any medication is to identify the client's medication allergies to prevent potential adverse reactions. Administering diazepam without knowing the client's allergies could lead to serious complications. Teaching the client about the medication's purpose is important but not as critical as ensuring the client does not have allergies. Administering the medication at the prescribed time is important but comes after ensuring safety. Documenting anxiety level is relevant but not as urgent as identifying allergies.
Question 4 of 5
A nurse is preparing to administer methylprednisolone acetate (Depo-Medrol) 10 mg by IV bolus. The amount available is 40 mg/mL. How many mL should the nurse administer?
Correct Answer: 0.3
Rationale:
Correct
Answer: 0.3 mL
Rationale:
1. Calculate the total dose needed: 10 mg.
2. Determine the concentration: 40 mg/mL.
3. Use the formula: dose needed / concentration available = volume to administer.
4. Plug in the values: 10 mg / 40 mg/mL = 0.25 mL.
5. Round up to the nearest practical dose increment: 0.3 mL.
Summary:
Choice A (0.5 mL): Incorrect, as it does not accurately calculate the volume needed.
Choices B-G: Irrelevant, as they do not follow the correct calculation method.
Question 5 of 5
A nurse is preparing to administer lactated Ringer's (LR) IV 100 mL over 15 minutes. The nurse should set the infusion pump to deliver how many mL/hr?
Correct Answer: 400
Rationale: The correct answer is 400 mL/hr.
To calculate the mL/hr rate, we first convert the 15 minutes to hours (15 minutes ÷ 60 minutes = 0.25 hours).
Then, we divide the total volume (100 mL) by the time in hours (100 mL ÷ 0.25 hours = 400 mL/hr). This rate ensures the safe and accurate administration of 100 mL of LR over a 15-minute period. Other choices are incorrect because they do not accurately calculate the mL/hr rate based on the given parameters.
