Question 1 of 5
The physician has prescribed haloperidol (Haldol) for the patient with schizophrenia. What is the priority patient outcome?
Correct Answer: B
Rationale: Haloperidol, a conventional antipsychotic, treats schizophrenia by reducing positive symptoms like hallucinations, but its efficacy depends on adherence. The priority outcome is medication compliance, as relapse is common without consistent use, undermining all other goals. Adequate fluids and fiber mitigate side effects (e.g., constipation) but are secondary to ensuring treatment continuity. Decreased hallucinations is a desired effect, not an outcome ensuring it happens. Restlessness indicates side effects (e.g., akathisia), not a goal. Compliance is foundational, as schizophrenia's chronic nature requires long-term management, making choice B the nurse's primary focus for successful therapy.
Question 2 of 5
The nurse is working with a graduate nurse to prepare an intravenous dose of potassium. Which statement by the graduate nurse reflects a need for further teaching?
Correct Answer: D
Rationale: The statement "The intravenous potassium dose will be given undiluted" reflects a need for further teaching. Potassium should always be diluted before administration to reduce the risk of causing irritation or damage to the veins. Administration of concentrated potassium solution can lead to serious complications, including local tissue damage, phlebitis, and even cardiac arrest. It is essential to dilute intravenous potassium solutions to ensure safe administration and minimize the risk of adverse effects.
Question 3 of 5
A 52-year-old woman with a history of recurrent urinary tract infections complains of easy bruising as well as chronic fatigue. She is maintained on daily antibiotic prophylaxis with trimethoprim. Which of the following hematologic effects is likely as a result of long-term therapy with trimethoprim?
Correct Answer: B
Rationale: Trimethoprim's folate antagonism with long-term use causes megaloblastic anemia . Bruising and fatigue reflect impaired erythropoiesis. Aplastic anemia , microcytic , normocytic , and pernicious (E) don't fit. This reversible effect requires folate supplementation.
Question 4 of 5
Drugs may be excreted by any route in the body, except:
Correct Answer: D
Rationale: Saliva is not a common route for drug excretion. Drugs are primarily excreted from the body through various routes such as the kidneys (urine), lungs (exhaled air), gastrointestinal tract (feces), and tears (through the eyes). Saliva does not play a major role in drug excretion, as most drugs are not significantly eliminated through saliva.
Question 5 of 5
A 74-year-old professional golfer has chest pain that occurs toward the end of his golfing games. He says the pain usually goes away after one or two sublingual nitroglycerin tablets and rest. What type of angina is he experiencing?
Correct Answer: D
Rationale: The 74-year-old professional golfer is likely experiencing Prinzmetal™s angina, also known as variant angina. This type of angina is characterized by episodes of chest pain that occur at rest or during minimal physical exertion. It is caused by a spasm in the coronary arteries, leading to a temporary reduction or cessation of blood flow to the heart muscle. The chest pain associated with Prinzmetal™s angina can be severe and is often relieved by sublingual nitroglycerin, as described by the golfer. Additionally, the fact that the pain occurs towards the end of his golfing games suggests that it may be triggered by stress or exertion, common triggers for coronary artery spasm in Prinzmetal's angina.
