Which of the following describes a process of heat loss involving the transfer of heat from one surface to another?
- A. Radiation
- B. Conduction
- C. Convection
- D. Evaporation
Correct Answer: B
Rationale: Conduction is the process of heat transfer that occurs between objects or substances that are in direct contact with each other. In this process, heat is transferred from a hotter surface to a cooler surface through direct contact. This type of heat transfer does not involve the movement of the substances themselves, only the transfer of thermal energy.
Choice A, Radiation, is the transfer of heat in the form of electromagnetic waves and does not require a medium. Choice C, Convection, involves the transfer of heat through the movement of fluids (liquids or gases) due to density differences. Choice D, Evaporation, is a cooling process that involves the transformation of a liquid into a gas, absorbing heat in the process.

Which of the following is inappropriate in collecting midstream clean-catch urine specimen for urine analysis?
- A. Collect early in the morning, first voided specimen
- B. Do perineal care before specimen collection
- C. Collect 5 to 10 ml of urine
- D. Discard the first flow of urine
Correct Answer: C
Rationale: The inappropriate action in collecting a midstream clean-catch urine specimen for urine analysis is to collect only 5 to 10 ml of urine. Adequate urine volume of 30 to 60 ml is required for accurate testing. Collecting a small amount like 5 to 10 ml may lead to inaccurate results due to insufficient sample size. It is crucial to follow proper collection techniques, such as discarding the first flow of urine, performing perineal care, and collecting an adequate volume, to ensure reliable test results.
The nurse is teaching the client diagnosed with colon cancer who is scheduled for a colostomy the next day. Which behavior indicates the best method of applying adult teaching principles?
- A. The nurse repeats the information as indicated by the client's questions
- B. The nurse teaches all the information needed by the client in one session
- C. The nurse uses a video to explain with medical terms to the client
- D. The nurse waits until the client asks questions about the surgery
Correct Answer: A
Rationale: Choice A is the best method of applying adult teaching principles because repeating information and addressing the client's questions as they arise is effective for reinforcing learning in adults. This approach allows for clarification of doubts and ensures that the client understands the information provided. Choice B is incorrect as teaching all the information in one session may overwhelm the client and hinder retention. Choice C is incorrect as using medical terms without ensuring the client's understanding may lead to confusion. Choice D is incorrect because waiting for the client to ask questions may result in missed opportunities to address important information proactively.
Listed below are five categories that identify the responsibilities of the practical nurse manager in personnel management. Which of these categories is most appropriate for the task of 'listening and responding to soldiers' suggestions and complaints'?
- A. Accountability
- B. Personal/professional development
- C. Individual training
- D. Military appearance/physical condition
Correct Answer: A
Rationale: The correct answer is A. Accountability in personnel management involves being answerable for one's actions and decisions, which includes listening to and addressing the suggestions and complaints of soldiers. This category focuses on the responsibility and answerability aspect of the nurse manager's role. Choices B, C, and D are incorrect because personal/professional development is about growth and improvement, individual training pertains to specific skill development, and military appearance/physical condition relates to the physical presentation and fitness levels, none of which directly address the task of listening and responding to soldiers' suggestions and complaints.
The client diagnosed with acute vein thrombosis is receiving a continuous heparin drip, an intravenous anticoagulant. The health care provider orders warfarin (Coumadin), an oral anticoagulant. Which action should the nurse take?
- A. Discontinue the heparin drip prior to initiating the Coumadin
- B. Check the client's INR prior to beginning Coumadin
- C. Clarify the order with the health care provider as soon as possible
- D. Administer the Coumadin along with the heparin drip as ordered
Correct Answer: D
Rationale: The correct action for the nurse to take is to administer the Coumadin along with the heparin drip as ordered. Heparin and warfarin are often given together initially because warfarin takes a few days to become effective. Discontinuing the heparin drip prior to initiating Coumadin could leave the patient without anticoagulation coverage during the period when warfarin's effects are not yet established. Checking the client's INR prior to beginning Coumadin is important but not the immediate action to take when both medications are ordered together. Clarifying the order with the health care provider is unnecessary in this scenario as it is common practice to give heparin and warfarin concurrently in the transition period.
Which nutrient deficiency is most likely to be seen in patients with chronic alcoholism?
- A. Vitamin C
- B. Vitamin D
- C. Vitamin B12
- D. Vitamin B1
Correct Answer: D
Rationale: In patients with chronic alcoholism, the most likely nutrient deficiency is Vitamin B1 (thiamine), not Vitamin B12. Chronic alcoholism often leads to Vitamin B1 deficiency, causing conditions like Wernicke's encephalopathy. While other vitamin deficiencies can also occur in chronic alcoholism, such as Vitamin C and Vitamin D, Vitamin B1 deficiency is more commonly associated with alcoholism.
