ATI Pharmacology Proctored Exam
1. 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.
2. What is the primary use of lithium?
- A. Lower blood glucose
- B. Slow the heart rate
- C. Stabilize mood
- D. Heal ulcers
Correct answer: C
Rationale: The correct answer is C: Stabilize mood. Lithium is primarily used to stabilize mood, especially in conditions like bipolar disorder. It helps in reducing the frequency and severity of manic episodes, making it an essential medication for mood stabilization. Choices A, B, and D are incorrect as lithium is not used to lower blood glucose, slow the heart rate, or heal ulcers.
3. A client with heart failure is being instructed on laxative use. Which of the following laxatives should the client avoid?
- A. Sodium phosphate
- B. Psyllium
- C. Bisacodyl
- D. Polyethylene glycol
Correct answer: A
Rationale: The correct answer is A: Sodium phosphate. Clients with heart failure often follow a sodium-restricted diet. Sodium phosphate laxatives can lead to sodium absorption, causing fluid retention, which is contraindicated in heart failure. It is crucial to avoid sodium phosphate laxatives in these clients to prevent exacerbation of fluid overload and heart failure symptoms. Psyllium (choice B), Bisacodyl (choice C), and Polyethylene glycol (choice D) are not contraindicated in clients with heart failure and can be used safely for bowel management.
4. A client with chronic renal disease is receiving therapy with epoetin alfa. Which of the following laboratory results should the nurse review for an indication of a therapeutic effect of the medication?
- A. The leukocyte count
- B. The platelet count
- C. The hematocrit (Hct)
- D. The erythrocyte sedimentation rate (ESR)
Correct answer: C
Rationale: The correct answer is C: The hematocrit (Hct). Monitoring the hematocrit is essential to assess the therapeutic effect of epoetin alfa because this medication stimulates red blood cell production in clients with chronic renal disease. The leukocyte count (choice A) and platelet count (choice B) are not directly affected by epoetin alfa therapy. The erythrocyte sedimentation rate (ESR) (choice D) is a non-specific marker of inflammation and is not used to monitor the therapeutic effect of epoetin alfa.
5. A client is being discharged and will start long-term oral prednisone for chronic asthma treatment. The client should monitor for which of the following adverse effects of this medication?
- A. Weight gain
- B. Nervousness
- C. Bradycardia
- D. Constipation
Correct answer: A
Rationale: Weight gain is an adverse effect of oral prednisone due to sodium and water retention, which leads to fluid retention. This can be monitored by tracking weight changes. Nervousness (Choice B) is not a common adverse effect of prednisone. Bradycardia (Choice C) is not typically associated with prednisone use; in fact, tachycardia can be more common. Constipation (Choice D) is not a prominent adverse effect of prednisone.
