ATI Pharmacology Proctored Exam

Correct Answer: C

Rationale: The correct answer is C: 'Brush and floss your teeth regularly.' Phenytoin can cause gingival hyperplasia, a condition that leads to overgrowth of gum tissue. Good oral hygiene practices such as regular brushing and flossing can help prevent or minimize this side effect. In contrast, choices A, B, and D are not directly related to managing the side effects of Phenytoin. Taking the medication at bedtime (choice A) is not a specific instruction related to oral hygiene. Increasing calcium-rich foods intake (choice B) may be beneficial for bone health but is not directly related to preventing gingival hyperplasia. Avoiding foods high in potassium (choice D) is not a necessary instruction for a client taking Phenytoin.

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.

Correct Answer: C

Rationale: When starting therapy with Lisinopril, a client should be instructed to monitor for a persistent dry cough as an adverse effect. Lisinopril, an ACE inhibitor, commonly causes this cough as an adverse effect. It is important for the client to monitor for this symptom and notify their healthcare provider if it occurs. Choices A, B, and D are incorrect because tinnitus, diarrhea, and weight gain are not commonly associated adverse effects of Lisinopril.

Correct Answer: A

Rationale: Clients prescribed Warfarin should avoid foods high in vitamin K, like broccoli, as they can counteract the medication's effectiveness. Warfarin works by inhibiting vitamin K-dependent clotting factors, so consuming high vitamin K foods can interfere with its anticoagulant effects. Bananas, chicken, and potatoes are not high in vitamin K and do not have a significant impact on Warfarin therapy.

Correct Answer: D

Rationale: The healthcare professional should prioritize assessing the client's respiratory rate because respiratory depression is a life-threatening adverse effect of Morphine. Monitoring the respiratory rate allows for early detection of potential complications and timely intervention to prevent harm. Assessing urine output, bowel sounds, and pain level are important but should come after ensuring the client's respiratory status is stable as it is the most critical assessment to prevent serious complications associated with opioid use.
