ATI Pharmacology Proctored Exam

Correct Answer: D

Rationale: Propranolol is contraindicated in clients with first-degree heart block due to its negative inotropic and chronotropic effects. The nurse should report this finding to the provider to consider an alternative therapy to prevent potential worsening of cardiac conduction abnormalities. Choices A, B, and C are not directly contraindications to Propranolol therapy for migraine headaches and do not pose immediate risks that would require reporting to the provider.

Correct Answer: C

Rationale: Muscle rigidity and a sudden rise in temperature are indicative of malignant hyperthermia, a potential complication of succinylcholine. Dantrolene is the drug of choice to treat malignant hyperthermia as it acts on skeletal muscles to reduce metabolic activity and counteract the symptoms. Neostigmine (Choice A) is used to reverse the effects of non-depolarizing neuromuscular blocking agents, not for malignant hyperthermia. Naloxone (Choice B) is an opioid antagonist used for opioid overdose. Vecuronium (Choice D) is a non-depolarizing neuromuscular blocking agent and is not the appropriate medication for malignant hyperthermia.

Correct Answer: A

Rationale: Folic acid supplementation is crucial for clients undergoing methotrexate treatment because methotrexate functions as a folic acid antagonist. By supplementing with folic acid, the risk of methotrexate toxicity can be minimized, improving the treatment's effectiveness and safety. Vitamin D, calcium, and iron are not specifically recommended in conjunction with methotrexate therapy and may not provide the same protective benefits as folic acid.

Correct Answer: B

Rationale: Enalapril, an ACE inhibitor, can cause hyperkalemia as an adverse effect due to decreased aldosterone levels, leading to potassium retention. Monitoring potassium levels is essential to prevent complications associated with hyperkalemia. Bradycardia (Choice A) is not a common adverse effect of Enalapril. Enalapril does not typically affect glucose levels, so hypoglycemia (Choice C) is not a common concern with this medication. Enalapril does not directly impact calcium levels, so hypocalcemia (Choice D) is not a typical adverse effect.

Correct Answer: A

Rationale: The priority assessment for a healthcare provider preparing to administer an IV bolus of Morphine is the client's respiratory rate. Morphine can cause respiratory depression as a significant adverse effect, so monitoring the respiratory rate is crucial to detect any signs of respiratory compromise and intervene promptly. Assessing the respiratory rate takes precedence over other assessments because respiratory depression can lead to serious complications. While pain level, blood pressure, and level of consciousness are important assessments, they are not the priority when administering Morphine, as the risk of respiratory depression is a more immediate concern.
