Test Bank Pharmacology and the Nursing Process Questions
Question 1 of 5
Antihistamines are used cautiously in older men with prostatic hypertrophy for which of the ff reasons?
Correct Answer: B
Rationale: The correct answer is B: Because these clients may experience difficulty voiding. Antihistamines can worsen urinary symptoms in men with prostatic hypertrophy by causing urinary retention. This is due to the anticholinergic effects of antihistamines, which can lead to decreased bladder contraction and difficulty in voiding. Increased drowsiness (choice A) is a common side effect of antihistamines but is not specific to older men with prostatic hypertrophy. Choice C, greater risk of cardiac arrest, is not directly related to the use of antihistamines in older men with prostatic hypertrophy. Choice D, lower autoimmune response in clients with AIDS, is unrelated to the use of antihistamines in older men with prostatic hypertrophy.
Question 2 of 5
A client with rheumatoid arthritis is about to begin aspirin therapy to reduce inflammation. When teaching the client about aspirin, the nurse discusses adverse reactions to prolonged aspirin therapy. These include:
Correct Answer: B
Rationale: The correct answer is B: Respiratory acidosis. Aspirin can lead to respiratory acidosis due to its effect on the respiratory center in the brainstem. It causes hyperventilation, leading to respiratory alkalosis initially, followed by respiratory acidosis as compensation mechanism fails. Weight gain is not a typical adverse reaction of aspirin. Fine motor tremors are not associated with aspirin therapy. Bilateral hearing loss is a rare but serious side effect of aspirin overdose, not prolonged therapy.
Question 3 of 5
A client with idiopathic thrombocytopenic purpura (ITP), an autoimmune disorder, is admitted to an acute care facility. Concerned about hemorrhage, the nurse monitors the client’s platelet count and observes closely for signs and symptoms of bleeding. The client is at greatest risk for cerebral hemorrhage when the platelet count falls below:
Correct Answer: B
Rationale: The correct answer is B: 20,000/ul. A platelet count below 20,000/ul puts the client at the highest risk for cerebral hemorrhage due to severe thrombocytopenia. Platelets are essential for blood clotting, and a low count increases the risk of spontaneous bleeding, especially in critical organs like the brain. Choices A, C, and D have platelet counts that are higher than the critical level of 20,000/ul, so they do not pose as high a risk for cerebral hemorrhage. Option D, 500/ul, is extremely low and would likely lead to severe bleeding, but the critical threshold for cerebral hemorrhage is considered to be around 20,000/ul.
Question 4 of 5
A client with rheumatoid arthritis is being discharged with a prescription for aspirin (Ecotrin), 600mg PO every 6 hours. The nurse should instruct the client to notify the physician if which adverse drug reaction occurs?
Correct Answer: B
Rationale: The correct answer is B: Tinnitus. Aspirin can cause tinnitus (ringing in the ears) as an adverse drug reaction, which can indicate potential ototoxicity. Tinnitus is an important side effect that should be reported promptly to the physician to prevent further auditory complications. Dysuria (A), leg cramps (C), and constipation (D) are not typically associated with aspirin use and are less urgent compared to tinnitus. Reporting these side effects may still be necessary but are not as critical as tinnitus in this scenario.
Question 5 of 5
The nurse is caring for a client with thrombocytopenia. What is the best way to protect this client?
Correct Answer: C
Rationale: The correct answer is C: Use the smallest needle possible for injections. In a client with thrombocytopenia (low platelet count), there is an increased risk of bleeding and bruising. Using the smallest needle possible for injections reduces the risk of causing injury to blood vessels and tissues, minimizing bleeding complications. Limiting visits by family members (choice A) is not directly related to protecting the client's safety. Encouraging wheelchair use (choice B) is not necessary unless indicated for mobility reasons. Maintaining accurate fluid intake and output records (choice D) is important for overall client care but does not directly address the risk of bleeding in thrombocytopenia.
