1. What is the best lab test to diagnose disseminated intravascular coagulation (DIC)?
- A. platelet count
- B. prothrombin time (PT)
- C. partial thromboplastin time (PTT)
- D. D-dimer
Correct answer: D-dimer
Rationale: The best lab test to diagnose disseminated intravascular coagulation (DIC) is the D-dimer test. In DIC, numerous small clots form throughout the body and are rapidly broken down. D-dimer measures a specific fibrin split product and is the most specific test for DIC. Platelet count (Choice A) is decreased in DIC due to consumption, but it is not specific for diagnosing DIC. Prothrombin time (PT - Choice B) and partial thromboplastin time (PTT - Choice C) are both elevated in DIC because clotting factors have been used up, but they are not specific for DIC as they can be elevated in other conditions as well.
2. When working with elderly clients, the healthcare provider should keep in mind that falls are most likely to happen to the elderly who are:
- A. in their 80s.
- B. living at home.
- C. hospitalized.
- D. living on only Social Security income.
Correct answer: hospitalized.
Rationale: The correct answer is 'hospitalized.' Elderly individuals are at a higher risk of falls, especially when they are in new environments like hospitals due to unfamiliarity with the surroundings, medications, and potential mobility challenges. Being in a hospital can disrupt their usual routines and increase the risk of falls. Choice A ('in their 80s') is not as directly related to the increased risk of falls in a hospital environment. Choice B ('living at home') is a common setting for the elderly but does not address the specific risk associated with being hospitalized. Choice D ('living on only Social Security income') is unrelated to the risk of falls based on the environment.
3. The nurse is caring for a client who is dying. While assessing the client for signs of impending death, the nurse observes the client for:
- A. elevated blood pressure.
- B. Cheyne-Stokes respiration.
- C. elevated pulse rate.
- D. decreased temperature.
Correct answer: Cheyne-Stokes respiration.
Rationale: Cheyne-Stokes respirations are a pattern of breathing characterized by rhythmic waxing and waning of respirations from very deep to very shallow breathing with periods of temporary apnea. This pattern is often associated with conditions like cardiac failure and can be a sign of impending death. Elevated blood pressure and pulse rate are not typically associated with the dying process. Decreased temperature is also not a common sign of impending death. Therefore, option B, Cheyne-Stokes respiration, is the correct choice when assessing a client for signs of impending death.
4. Which direction given to the nursing assistant is most likely to accomplish the task of getting a urine specimen delivered to the lab immediately after collection?
- A. “Make it a stat delivery.”
- B. “Please do it as soon as you can after break.”
- C. “This client is delirious, and we’re worried about urinary sepsis.”
- D. “Take this client to the bathroom now and collect a urine specimen from this voiding. Take the specimen to the lab immediately.”
Correct answer: “Take this client to the bathroom now and collect a urine specimen from this voiding. Take the specimen to the lab immediately.”
Rationale: Effective delegation depends on clear, concise direction that leaves no room for question or interpretation on the part of the one being delegated to. In this scenario, the most appropriate direction is to ensure the urine specimen is collected promptly and delivered to the lab immediately. Choice A is too vague and does not specify the urgency required. Choice B does not emphasize the immediate need for the specimen to be delivered. Choice C introduces unnecessary medical information that is beyond the scope of a nursing assistant and may cause confusion. Therefore, choice D is the correct answer as it provides clear instructions for immediate action without room for misunderstanding.
5. In conducting a community health fair for a group of middle-aged citizens, which statement should the nurse emphasize in reducing the risk of coronary heart disease?
- A. Participate in at least 30 minutes of moderate physical activity 3 to 5 days per week.
- B. Engage in an aerobic exercise class every day.
- C. Limit your alcohol intake to a moderate level.
- D. The best way to lose weight is to follow a balanced diet.
Correct answer: Engage in an aerobic exercise class every day.
Rationale: Engaging in an aerobic exercise class every day is crucial in reducing the risk of coronary heart disease. Aerobic exercises help keep the heart in shape, lower blood pressure, and improve cholesterol levels. It is recommended to participate in at least 150 minutes of moderate-intensity aerobic exercise per week, which can be achieved by engaging in aerobic exercise daily. Choice A has been corrected to emphasize the frequency required to significantly reduce the risk of coronary heart disease. Choice C has been modified to suggest moderation in alcohol intake, as excessive alcohol consumption is harmful. Choice D is also incorrect as a balanced diet, not specifically high-protein, high-fat, is recommended to reduce the risk of coronary heart disease and maintain a healthy weight.
