ATI Pharmacology Proctored Exam
1. A client is admitted for a surgical procedure. Which preexisting condition can be a contraindication for the use of Ketamine as an intravenous anesthetic?
- A. Peptic ulcer disease
- B. Breast cancer
- C. Diabetes mellitus
- D. Schizophrenia
Correct answer: D
Rationale: Ketamine can produce psychological effects like hallucinations. Patients with schizophrenia may be more prone to experiencing exacerbation of their symptoms when exposed to Ketamine due to its potential to worsen psychotic symptoms. Therefore, schizophrenia can be a contraindication for the use of Ketamine as an anesthetic. Peptic ulcer disease, breast cancer, and diabetes mellitus are not contraindications for the use of Ketamine.
2. A nurse is providing teaching to a client who has a new prescription for Metoprolol. Which of the following statements should the nurse include?
- A. This medication may make you feel dizzy at first.
- B. You should avoid foods that are high in fat.
- C. Take the medication in the morning.
- D. You may experience a rapid heart rate while taking this medication.
Correct answer: A
Rationale: Metoprolol, a beta-blocker, can cause dizziness, especially when starting the medication. The nurse should inform the client to change positions slowly to avoid dizziness and falls.
3. A client in the post-anesthesia recovery unit received a nondepolarizing neuromuscular blocking agent and has muscle weakness. The nurse should anticipate a prescription for which of the following medications?
- A. Neostigmine
- B. Naloxone
- C. Dantrolene
- D. Vecuronium
Correct answer: A
Rationale: Neostigmine is a cholinesterase inhibitor commonly used to reverse the effects of nondepolarizing neuromuscular blockers, such as the one the client received. It works by inhibiting the breakdown of acetylcholine, thereby enhancing neuromuscular transmission and reversing muscle weakness caused by the neuromuscular blocking agent.
4. A client has a new prescription for Timolol. How should the nurse instruct the client to insert eye drops?
- A. Press your finger on the inside corner of your eye for 1 minute after application.
- B. Apply the eye drops directly to the cornea.
- C. Drop the prescribed amount of medication into the center of the conjunctival sac.
- D. Wipe your eyes gently with a tissue immediately after application.
Correct answer: C
Rationale: When administering eye drops, it is essential to instruct the client to drop the prescribed amount of medication into the center of the conjunctival sac. This technique helps ensure proper distribution of the medication and reduces the risk of potential adverse effects. Pressing on the inside corner of the eye is done to prevent systemic absorption, applying drops directly to the cornea can cause irritation, and wiping the eyes after application can lead to decreased effectiveness of the medication.
5. A client is undergoing preparation for extensive colorectal surgery. Which of the following oral antibiotics should be administered to suppress normal flora in the GI tract?
- A. Kanamycin
- B. Gentamicin
- C. Neomycin
- D. Tobramycin
Correct answer: C
Rationale: The correct answer is C: Neomycin. Neomycin, an aminoglycoside antibiotic, is administered orally before GI surgery to eliminate the normal flora in the large intestine. This helps reduce the risk of postoperative infections by decreasing the bacterial load in the gut. Choices A, B, and D (Kanamycin, Gentamicin, Tobramycin) are not typically used to suppress normal flora in the GI tract before colorectal surgery.
