1. The client has begun medication therapy with pancrelipase (Pancrease MT). The nurse evaluates that the medication is having the optimal intended benefit if which effect is observed?
- A. Weight loss
- B. Relief of heartburn
- C. Reduction of steatorrhea
- D. Absence of abdominal pain
Correct answer: C
Rationale: Pancrelipase (Pancrease MT) is a pancreatic enzyme replacement therapy used to aid digestion in clients with pancreatic insufficiency. One of the key goals of pancrelipase therapy is to reduce the amount of undigested fat in the stool, known as steatorrhea. Therefore, the nurse should evaluate the effectiveness of pancrelipase by looking for a reduction in steatorrhea, indicating improved digestion and absorption of fats.
2. A client who has a new prescription for warfarin (Coumadin) asks the nurse how the medication works. What explanation should the nurse provide?
- A. It dissolves blood clots
- B. It prevents the blood from clotting
- C. It thins the blood
- D. It decreases the risk of infection
Correct answer: B
Rationale: The correct answer is B: 'It prevents the blood from clotting.' Warfarin works by inhibiting the synthesis of vitamin K-dependent clotting factors in the liver, thereby preventing the formation of blood clots. Choice A is incorrect because warfarin does not dissolve existing blood clots but prevents new ones from forming. Choice C is partially correct but not as specific as choice B in explaining how warfarin works. Choice D is unrelated to the mechanism of action of warfarin and is incorrect.
3. An older client with chronic emphysema is admitted to the emergency room with acute weakness, palpitations, and vomiting. Which information is most important for the nurse to obtain during the initial interview?
- A. Recent compliance with prescribed medications.
- B. Sleep patterns during the previous few weeks.
- C. History of smoking over the past 6 months.
- D. Activity level prior to the onset of symptoms.
Correct answer: A
Rationale: The correct answer is A. In this scenario, the most critical information for the nurse to obtain during the initial interview is the recent compliance with prescribed medications. This is crucial to understand the client's baseline condition and management of chronic emphysema. Monitoring medication adherence can provide insights into potential exacerbating factors that may have led to the current acute symptoms. Choices B, C, and D are not as crucial in this situation. Sleep patterns, smoking history, and activity levels are important aspects of the client's overall health but do not take precedence over medication compliance when addressing acute symptoms in a client with chronic emphysema.
4. An adolescent with a history of bipolar disorder is hospitalized during a manic episode. Which intervention is most appropriate for the nurse to include in the care plan?
- A. Encourage high levels of physical activity.
- B. Provide a quiet and structured environment.
- C. Engage the client in creative arts activities.
- D. Allow the client to make decisions about their schedule.
Correct answer: B
Rationale: During a manic episode, individuals with bipolar disorder may experience heightened energy levels, decreased need for sleep, and racing thoughts. Providing a quiet and structured environment is crucial in managing these symptoms as it helps reduce external stimuli, prevent overstimulation, and promote a sense of calmness. Encouraging high levels of physical activity may exacerbate the manic symptoms by further increasing stimulation and excitement. Engaging the client in creative arts activities might be beneficial during stable periods but may not be the most appropriate intervention during a manic episode. Allowing the client to make decisions about their schedule could potentially lead to impulsivity and poor judgment, which are common characteristics of mania.
5. The nurse working in an emergency center collects physical evidence 6 hours following a reported sexual assault. After placing the samples in sealed containers, which action is most important for the nurse to implement?
- A. Maintain possession of the evidence collection kit at all times until submitted to law enforcement
- B. Provide discharge instructions for prophylactic antibiotics, pregnancy, and HIV prevention medication
- C. Document the characteristics of the various sites of sample collection
- D. Assist the client with toileting, hygiene, and dressing with clean clothes
Correct answer: A
Rationale: Maintaining possession of the evidence collection kit at all times until submitted to law enforcement is crucial to ensure the integrity of the chain of custody. This step helps prevent tampering or contamination of the evidence, which is vital for the legal process. Providing discharge instructions for medications, documenting sample characteristics, and assisting the client with personal care are important aspects of care but not the immediate priority when handling forensic evidence in a sexual assault case.
