Question 1 of 5
A client who is receiving edrophonium chloride suddenly is complaining of abdominal cramps and the nurse observes the client is experiencing increased perspiration and salivation. The nurse makes sure the availability of which of the following?
Correct Answer: C
Rationale: The symptoms of abdominal cramps, increased perspiration, and salivation suggest cholinergic excess, which can occur with edrophonium chloride. Atropine sulfate is the antidote for cholinergic toxicity and should be readily available to counteract these effects. Levodopa, methylphenidate, and carbamazepine are not used to treat cholinergic excess. Therefore, atropine is the correct medication to have on hand.
Question 2 of 5
With regard to oral anti-asthmatic agents:
Correct Answer: C
Rationale: Prednisone is intermediate-acting (12-36 hours), not long-acting like dexamethasone, so that's false. Methotrexate benefits some prednisone-dependent asthmatics, not all studies, making that false. Cyclosporin's toxicity (e.g., nephrotoxicity) limits its anti-asthmatic use, a true statement, despite immunosuppressive potential. Nifedipine has minimal effect on exercise-induced bronchoconstriction, unlike inhaled CCBs, so that's false. Macrolides show some benefit in asthma. Cyclosporin's limitation reflects its risk-benefit profile, restricting its practical use.
Question 3 of 5
Samuel, a 65-year-old patient comes into the hospital for an anginal attack. Which of the following is an important nursing intervention when administering Nitroglycerine?
Correct Answer: C
Rationale: It is important to remove the transdermal Nitroglycerine patch for 10-12 hours every night to prevent the development of tolerance. Tolerance can occur when the body becomes less responsive to the medication over time, reducing its effectiveness. By allowing a break in Nitroglycerine administration overnight, tolerance development can be minimized, ensuring the medication remains effective for the patient when needed. This nursing intervention helps to maintain the efficacy of Nitroglycerine in managing anginal attacks for the patient.
Question 4 of 5
The nurse is providing medication education to a client with hypertension. The nurse teaches the client that the physician ordered a diuretic to decrease the amount of fluid in the client's body. Which statement best describes the nurse's instruction?
Correct Answer: A
Rationale: Explaining a diuretic's role in reducing fluid for hypertension is appropriate education, informing the client about its purpose in a clear, relevant way. Mechanism (e.g., sodium excretion) wasn't detailed-purpose was. Prototype drugs weren't specified, and consequences of non-use weren't covered. Appropriate education fits, enhancing adherence by linking the drug to the condition, a practical teaching goal.
Question 5 of 5
A nurse is caring for a client who is receiving cyclobenzaprine hydrochloride (Flexeril) for the treatment of muscle spasm. Which of the following medical conditions is contraindicated with the use of the medication?
Correct Answer: B
Rationale: Cyclobenzaprine, a muscle relaxant, has anticholinergic effects that can exacerbate angle-closure glaucoma by increasing intraocular pressure. It is contraindicated in patients with this condition. While it may cause dry mouth or urinary retention, it is not specifically contraindicated in diabetes, emphysema, or urinary tract infections. The anticholinergic properties of cyclobenzaprine make it unsuitable for patients with angle-closure glaucoma.
