Nursing Elites

1. Which of the following measures the frequency of new cases of the phenomenon during a given period of time?

• A. prevalence rate
• B. proportionate mortality rate
• C. case fatality rate
• D. incidence rate

Correct answer: D

Rationale: The correct answer is D, incidence rate. Incidence rate measures the frequency of new cases of a phenomenon, providing important information about the risk of developing the condition. Prevalence rate (choice A) reflects both old and new cases, proportionate mortality rate (choice B) is the proportion of deaths due to a specific cause, and case fatality rate (choice C) measures the proportion of deaths among confirmed cases, not just new cases.

2. A client with peptic ulcer disease is receiving ranitidine (Zantac). The nurse should monitor the client for which of the following side effects?

• A. Hypertension
• B. Constipation
• C. Diarrhea
• D. Hypotension

Correct answer: C

Rationale: The correct answer is C: Diarrhea. Ranitidine, which is used to treat peptic ulcer disease, can lead to gastrointestinal disturbances such as diarrhea. Choices A, B, and D are incorrect. Hypertension and hypotension are not common side effects of ranitidine. Constipation is also not a typical side effect associated with ranitidine use.

3. Which individual has the highest risk of developing community-acquired pneumonia?

• A. A 40-year-old first-grade teacher who works with underprivileged children.
• B. A 75-year-old retired secretary with exercise-induced wheezing.
• C. A 60-year-old homeless person who is an alcoholic and smokes.
• D. A 35-year-old aerobics instructor who skips meals and eats only vegetables.

Correct answer: C

Rationale: The correct answer is the 60-year-old homeless person who is an alcoholic and smokes. This individual has the highest risk of developing community-acquired pneumonia due to factors such as homelessness, alcoholism, and smoking, which weaken the immune system and make them more susceptible to respiratory infections. Choice A is incorrect as working with underprivileged children, while potentially exposing the individual to various illnesses, does not directly increase the risk of pneumonia. Choice B is less likely as exercise-induced wheezing may suggest asthma but does not directly correlate with pneumonia risk. Choice D, an aerobics instructor who eats only vegetables and skips meals, does not have the same level of risk factors for pneumonia as the homeless person in choice C.

4. The RN is making a home visit to a female client with end-stage heart disease. She has a living will and states she will never go back to the hospital. During the visit, the RN notes that the client is pale and SOB while speaking. The RN discovers 3+ edema in both ankles and bilateral pulmonary crackles. Which intervention should the RN implement first?

• A. Order a chest X-ray
• B. Obtain a peripheral O2 saturation reading
• C. Obtain an order for complete blood count
• D. Tell the patient to stay in bed

Correct answer: B

Rationale: Obtaining a peripheral O2 saturation reading is the priority intervention in this scenario. It helps assess the client's oxygenation status quickly, which is crucial in a client with signs of respiratory distress, such as shortness of breath and bilateral pulmonary crackles. Ordering a chest X-ray (Choice A) may be necessary later but does not address the immediate need for oxygen assessment. Obtaining an order for a complete blood count (Choice C) is not the priority in this situation as it does not directly address the client's respiratory distress. Instructing the patient to stay in bed (Choice D) does not address the underlying issue of potential hypoxia and respiratory compromise.

5. A client presents at a community-based clinic with complaints of shortness of breath, headache, dizziness, and nausea. During the assessment, the nurse learns that the client is a migrant worker who often uses a gasoline-powered pressure washer to clean equipment and farm buildings. Which type of poisoning is the most likely etiology of this client's symptoms?

• A. asbestos
• B. silica dust
• C. histoplasmosis
• D. carbon monoxide

Correct answer: D

Rationale: The client's symptoms of shortness of breath, headache, dizziness, and nausea are indicative of carbon monoxide poisoning, which can result from exposure to gasoline-powered equipment like pressure washers. Asbestos (Choice A) exposure would typically present with respiratory issues and cancer but not the rapid onset of symptoms described. Silica dust (Choice B) exposure is associated with respiratory conditions like silicosis, not the multisystem symptoms in the scenario. Histoplasmosis (Choice C) is a fungal infection that primarily affects the lungs and is not related to the client's exposure to a gasoline-powered pressure washer.
