Nurs 1140 Pharm Exam Study Guide With Rationale

NURS 1140 PHARM EXAM STUDY GUIDE WITH RATIONALE Pharm Exam study guide A patient’s heart rate is found to be 72 beats per minute and regular. The nurse evaluates which situation in the patient’s peripheral nervous system? Standard Text: Select all that apply. 1. The sympathetic system is in control. 2. The parasympathetic system is dominating. 3. Both parasympathetic and sympathetic systems are influencing cardiac status. 4. The autonomic nervous system is affecting cardiac status. 5. The somatic nervous system is affecting cardiac status. Correct Answer: 2,3,4 Rationale 2: Restful cardiac response indicates that the primary input is from the parasympathetic system. Rationale 3: These two systems work in tandem to regulate the cardiac response. Rationale 4: Both the sympathetic and parasympathetic systems are part of the autonomic system. 2. A nurse is reading about the development of drugs that inhibit the parasympathetic nervous system. The nurse would look for articles about which drug classes? Standard Text: Select all that apply. 1. Anticholinergics 2. Parasympathomimetics 3. Parasympatholytics 4. Cholinergics 5. Muscarinic blockers Correct Answer: 1,3,5 Rationale 1: Anticholinergics inhibit the parasympathetic nervous system. Rationale 3: Parasympatholytic drugs inhibit the parasympathetic nervous system. Rationale 5: Muscarinic blockers inhibit the parasympathetic nervous system. Question 3 Type: Hot Spot Mark the site of the ganglionic synapse on this diagram. 1. A 2. B 3. C 4. D Answer: 3 Rationale: The ganglionic synapse is the gap between the preganglionic neuron and the postganglionic neuron. Question 4 Type: MCMA A patient has been prescribed an oral drug containing atropine. The nurse would hold the drug and Contact the prescriber if which patient statements are made? Standard Text: Select all that apply. 1. “I would like to wait a few minutes to take this as I just drank some aloe juice.” 2. “Can I take this at the same time as my procainamide?” 3. “I have had a headache this morning.” 4. “I am allergic to penicillin.” 5. “My gallbladder surgery is scheduled for next week.” Correct Answer: 1,2 Rationale 1: Atropine should be used with caution in those who use aloe. Rationale 2: There is a drug–drug interaction between atropine and procainamide. Question 5 Type: MCSA The nurse has completed medication education about pyridostigmine (Mestinon), an indirect cholinergic drug, for the patient with myasthenia gravis. The nurse determines that learning has occurred when the patient makes which statement? 1. "My heart may beat slower while I am on this drug." 2. "I will need to increase my fluid intake with this medication." 3. "I must take this medication immediately before eating a full meal." 4. "It is really important to take my medication on time." Correct Answer: 4 Rationale 4: Maintaining an optimum blood level of the drug is crucial in promoting muscle functioning, so it is important for the patient to take his medication on time and as directed. Question 6 Type: MCSA The physician has ordered bethanechol (Urecholine), a cholinergic drug, for the patient with urinary retention. The patient also has an enlarged prostate gland. What is the priority action by the nurse? 1. Hold the drug and prepare to cath
