Epinephrine - correct answers.B. Neostigmine bromide Neostigmine bromide and atropine sulfate, both anticholinergic drugs, reverse the respiratory muscle paralysis caused by pancuronium bromide.

Which complication is assessed through frequent laboratory testing that the nurse should explain to this mother? A. Nephrotoxicity B. Ototoxicity C. Myelosuppression D.Hepatotoxicity - correct answers.C. Myelosuppression Myelosuppression is the highest priority complication that can potentially affect clients managed with carbamazepine therapy.

A client who has trouble swallowing pills intermittently has been prescribed venlafaxine (XR) for depression. The medication comes in capsule form. What should the nurse include in the discharge teaching plan for this client? A. Capsule contents can be sprinkled on pudding or applesauce. B. Chew the medication thoroughly to enhance absorption. C. Take the medication with a large glass of water or juice. D. Contact the health care provider for another form of medication. - correct answers.D. Contact the health care provider for another form of medication. Venlafaxine is administered PO in capsule form. Capsules that are extended-release (XR) or continuous-release (CR) contain delayed-release, enteric-coated granules to prevent decomposition of the drug in the acidic pH of the stomach. The client should notify the health care provider about the inability to swallow the capsule. This medication should not be chewed or opened so that the delayed-release, enteric-coated granules can remain intact. Water or juice will not affect the medication. The nurse is preparing to apply a surface anesthetic agent for a client. Which action should the nurse implement to reduce the risk of systemic absorption? A. Apply the anesthetic to mucous membranes. B. Limit the area of application to inflamed areas. C. Avoid abraded skin areas when applying the anesthetic. D. Spread the topical agent over a large surface area. - correct answers.C. Avoid abraded skin areas when applying the anesthetic. To minimize systemic absorption of topical anesthetics, the anesthetic agent should be applied to the smallest surface area of intact skin. Application to the mucous membranes poses the greatest risk of systemic absorption because absorption occurs more readily through mucous membranes than through the skin. Inflamed areas generally have an increased blood supply, which increases the risk of systemic absorption, so option B should be avoided. A large surface area increases the amount of topical drug that is available for transdermal absorption, so the smallest area should be covered, not option D. A client experiencing dysrhythmias is given quinidine, 300 mg PO every 6 hours. The nurse plans to observe this client for which common side effect associated with the use of this medication? A. Diarrhea B. Hypothermia C. Seizures D. Dysphagia - correct answers.A. Diarrhea The most common side effects associated with quinidine therapy are gastrointestinal complaints, such as diarrhea.

Gastric acid secreted at night is buffered, preventing pepsin formation. B. Hydrochloric acid secreted during the night is blocked. C. The drug relaxes stomach muscles at night to reduce acid. D. Ingestion of the medication at night offers a sedative effect, pr - correct answers.B. Hydrochloric acid secreted during the night is blocked. H2 antagonists act on the parietal cells to inhibit gastric secretion. Some gastric secretion occurs all the time, even when the stomach is empty, unless medications are taken to inhibit this action. Options C and D are not actions of famotidine. Option A is the action of antacids. Antacids do not affect healing or prevent the recurrence of ulcers; they merely provide symptomatic relief. Knowing the difference between H2 antagonists and antacids is important when teaching clients. The nurse is preparing to administer the disease-modifying antirheumatic drug (DMARD) methotrexate to a client diagnosed with rheumatoid arthritis.
