1. A nurse reviewing a client's medical record notes a new prescription for verifying the trough level of the client's medication. Which of the following actions should the nurse take?
- A. Obtain a blood specimen immediately prior to administering the next dose of medication.
- B. Verify that the client has been taking the medication for 24 hours before obtaining a blood specimen.
- C. Ask the client to provide a urine specimen after the next dose of medication.
- D. Administer the medication and obtain a blood specimen 30 minutes later.
Correct answer: A
Rationale: To verify the trough levels of a medication accurately, the nurse should obtain a blood specimen immediately before administering the next dose of the medication. The trough level represents the lowest concentration of the medication in the bloodstream, typically right before the next dose is due. This timing ensures an accurate assessment of the drug's concentration in the body at its lowest point, aiding in determining the drug's effectiveness and potential toxicity levels. Choice B is incorrect because waiting for 24 hours would not provide the trough level. Choice C is incorrect as urine specimens are not used to measure trough levels. Choice D is incorrect as obtaining a blood specimen 30 minutes after administering the medication would not reflect the trough level.
2. A nurse is evaluating teaching for a client who has Rheumatoid Arthritis and a new prescription for Methotrexate. Which of the following statements by the client indicates understanding of the teaching?
- A. I will be sure to return to the clinic at least once a year to have my blood drawn while I'm taking methotrexate.
- B. I will take this medication on an empty stomach.
- C. I'll let the doctor know if I develop sores in my mouth while taking this medication.
- D. I should stop taking oral contraceptives while I'm taking methotrexate.
Correct answer: C
Rationale: Ulcerations in the mouth, tongue, or throat are often the first signs of methotrexate toxicity and should be reported to the provider immediately.
3. A client has a Cerebrospinal fluid infection with gram-negative bacteria. Which of the following Cephalosporin antibiotics should be administered IV to treat this infection?
- A. Cefaclor
- B. Cefazolin
- C. Cefepime
- D. Cephalexin
Correct answer: C
Rationale: In treating a Cerebrospinal fluid infection caused by gram-negative bacteria, Cefepime, a fourth-generation cephalosporin, is the most suitable choice due to its enhanced efficacy against gram-negative organisms in such infections. Cefaclor (Choice A) is a second-generation cephalosporin more commonly used for respiratory tract infections. Cefazolin (Choice B) is a first-generation cephalosporin often used for skin and soft tissue infections. Cephalexin (Choice D) is a first-generation cephalosporin indicated for skin and urinary tract infections, but not the optimal choice for a Cerebrospinal fluid infection with gram-negative bacteria.
4. A client in the operating room received a dose of Succinylcholine. During the operation, the client suddenly develops rigidity, and their body temperature begins to rise. The healthcare provider should anticipate a prescription for which of the following medications?
- A. Neostigmine
- B. Naloxone
- C. Dantrolene
- D. Vecuronium
Correct answer: C
Rationale: Muscle rigidity and a sudden rise in temperature are manifestations of malignant hyperthermia. Dantrolene acts on skeletal muscles to reduce metabolic activity and treat malignant hyperthermia effectively. Neostigmine (choice A) is used to reverse the effects of non-depolarizing neuromuscular blockers, not to treat malignant hyperthermia. Naloxone (choice B) is an opioid antagonist used for opioid overdose. Vecuronium (choice D) is a non-depolarizing neuromuscular blocker and is not used to treat malignant hyperthermia.
5. A healthcare professional is reviewing the medical history of a client who has a new prescription for Metformin to treat type 2 diabetes. Which of the following findings should the healthcare professional report to the provider?
- A. Hemoglobin A1C of 7.5%
- B. Creatinine level of 1.2 mg/dL
- C. BUN level of 18 mg/dL
- D. Liver function tests showing AST of 50 units/L
Correct answer: D
Rationale: The correct answer is D. Elevated AST levels in liver function tests should be reported to the provider when a client is prescribed Metformin due to the potential risk of hepatotoxicity associated with the medication. Elevated Hemoglobin A1C (choice A), Creatinine level within normal range (choice B), and BUN level within normal range (choice C) are not directly concerning when initiating Metformin therapy.
