A. Weigh the infant
B. Stop the oral feedings
C. Dilute the clear liquids with sterile water
D. Check the stool for reducing substances
50. To which of the following nursing diagnoses should a nurse give priorityin the care of a client who is receiving chemotherapy for treatment of breast cancer?
A. Risk for infection
B. Altered nutrition: less than body requirements
C. Altered sexuality patterns
D. Impaired physical mobility
51. A woman who is 34 weeks pregnant should be instructed to notify a nurse in the prenatal clinic immediately if which of these symptoms develops?
A. Postprandial heartburn
B. Hard stools
C. Facial edema
D. Afternoon fatigue
Rationales
49. Key: B Client Need: Management of Care
B. Oral feedings should be stopped and the infant hydrated by other means, since the infant is unable to tolerate oral feedings.
A. The infant would be weighed daily but it is not the priority action in this case.
C. Oral fluids should be stopped and the infant hydrated by other means.
D. Checking the stool for reducing substances is not a priority action.
50. Key: A Client Need: Safety and Infection Control
A. Chemotherapeutic agents cause bone marrow suppression. This results indecreased leukocytes, erythrocytes and platelets. Decreased white cells cause immunosuppression, which can lead to infection, sepsis and death. Loss of red bloodcells and platelets may result in fatigue and bleeding (GI bleeding andhypovolemic shock). The effects of bone marrow suppression can be lifethreatening.
B. Chemotherapy can lead to malnutrition due to nausea, vomiting and stomatitis. Nutrition is important but not the number one priority.
C. Breast cancer impacts on a woman’s sexuality and self-image. This is especially important in women who are surgically treated for breast cancer. Nursing care for mastectomy clients should involve supporting the woman as shecopes with her changed body image. Support should also be provided to thewoman’s significant other. This is an important part of care but not the priority for women receiving chemotherapy for breast cancer treatment.
D. Impaired physical mobility is usually not a result of chemotherapy. Fatigue due to bone marrow suppression can negatively affect one’s activity level and ability to complete activities of daily living.
51. Key: C ClientNeed: Health Promotion and Maintenance
C. Facial edema may be indicative of pre eclampsia and should be reportedimmediately.
A. This is an anticipated finding because the expanding uterus putspressure on the stomach. The finding does not require immediate intervention.
B. The pressure of the growing fetus can interfere with normal bowelfunction. The finding does not require immediate intervention.
D. Afternoon fatigue is anticipated in the third trimester.。

ISPN考试模拟试题(三十)Practice Test Questions88. The nurse hears a client calling out for help, hurries down the hallway to the client’s room and finds the client lying on the floor. The nurse performs an assessment, assists the client back to bed, notifies the health care provider of the incident, and completes an incident report. Which statement should the nurse document on the incident report?1. The client fell out of bed.2. The client climbed over the side rails.3. The client was found lying on the floor.4. The client became restless and tried to get out of bed.89. A client is brought to the emergency department by emergency medical services (EMS) after being hit by a car. The name of the client is unknown, and the client has sustained a severe head injury and multiple fractures and is unconscious. An emergency craniotomy is required. Regarding informed consent for the surgical procedure, which is the best action?1. Obtain a court order for the surgical procedure.2. Ask the EMS team to sign the informed consent.3. Transport the victim to the operating room for surgery.4. Call the police to identify the client and locate the family.90. The nurse has just assisted a client back to bed after a fall. The nurse and health care provider have assessed the client and have determined that the client is not injured. After completing the incident report, the nurse should implement which action next?1. Reassess the client.2. Conduct a staff meeting to describe the fall.3. Document in the nurse’s notes that an incident report was completed.4. Contact the nursing supervisor to update information regarding the fall. 88. 3Rationale:The incident report should contain the client’s name, age, and diagnosis. The report should contain a factual description of the incident, any injuries experienced by those involved, and the outcome of the situation. The correct option is the only one that describes the facts as observed by the nurse. Options 1, 2, and 4 are interpretations of the situation and are not factual information as observed by the nurse.Test-Taking Strategy: Focus on the subject, documentation ofevents, and read the information in the question to select when documenting, and avoid including interpretations. This will direct you to the correctoption.Client Needs: Safe and Effective Care Environment89. 3Rationale: In general, there are two situations in which informed consent ofan adult client is not needed. One is when an emergency is present and delaying treatment for the purpose of obtaining informed consent would result in injury or death to the client. The second is when the client waives the right to give informed consent. Option 1 will delay emergency treatment, and option 2 is inappropriate. Although option 4 may be pursued, it is not the best action.Test-Taking Strategy: Note the strategic word best. Recalling that when an emergency is present and a delay in treatment for the purpose of obtaining informed consent could result in injury or death will direct you tothe correct option.Client Needs: Safe and Effective Care Environment90. 1Rationale: After a client’s fall, the nurse must frequently reassess the client because potential complications do not always appearimmediately after that fall. The client’s fall should be treated as private information and shared on a “need to know” basis. Communication regarding the event should involve only the individuals participating in the client’s care. An incident report is aproblem-solving document; however, its completion is not documented in the nurse’s notes. If the nursing supervisor has been made aware of the incident, the supervisor will contact the nurse if status update is necessary.Test-Taking Strategy: Focus on the data in the question and thestrategic word next. Using the steps of the nursing process will direct you to the correct option. Remember that assessment is the first step.。
ISPN考试模拟试题(二十五)
ISPN考试模拟试题(二十六)Practice Test Questions76. The ambulatory care nurse is discussing preoperative procedures with a Japanese American client who is scheduled for surgery the following week. During the discussion, the client continually smiles and nods the head. How should the nurse interpret this nonverbal behavior?1. Reflecting a cultural value2. An acceptance of the treatment3. Client agreement to the required procedures4. Client understanding of the preoperative procedures77. When communicating with a client who speaks a different language, which best practice should the nurse implement?1. Speak loudly and slowly2. Arrange for an interpreter to translate3. Speak to the client and family together4. Stand close to the client and speak loudly78. The nurse educator is providing in-sevice education to the nursing staff regarding transcultural nursing care;a staff member asks the nurse educator to describe the concept of acculturation. The nurse educator should make which most appropriate response?1. “It is a process of learning a differ ent culture to adapt to a new or changing environment.”2. “It is a subjective perspective of theperson’s heritage and a sense of belonging to a group.”3. “It is a group of individuals in society who are culturally distinct and have a unique identity.”4. “It is a group that shares some of the characteristics of the larger population group of which it is a part.”76. Rationales: Nodding or smiling by a Japanese American client may reflect only the cultural value of interpersonal harmony. This nonverbal behavior may not be an indication of acceptance of the treatment, agreement with the speaker, or understanding of the procedure.Test-Taking Strategy: Eliminate options 2 and 3 first because they are comparable or alike. From the remaining options, select the correct option because it is characteristic of Asian American cultures. In addition, option 4 is an incorrect interpretation of the client’s nonverbal behavior.Client Needs: Psychosocial Integrity77. Rationale: Arranging for an interpreter would be the best practice when communicating witha client who speaks a different language. Options 1 and 4 are inappropriate and are ineffective ways to communicate. Option 3 is inappropriate because it violates privacy and does not ensure correct translation.Test-Taking Strategy: Note the strategic word best in the question. Eliminate option 3 first because it violates the client’s right toprivacy. Next, eliminate options 1 and 4 noting the word loudly in theseoptions and because they are non therapeutic translation.Client Needs: Psychosocial Integrity78. Rationale: Acculturation is a process of learning a different culture to adapt to anew or changing environment. Option 2 describes ethnic identity. Option 3 describes an ethnic group. Option 4 describes a subculture.Test-Taking Strategy: Note the strategic words most appropriate.Focus on the subject, acculturation. Think about the definition ofacculturation to help direct you to the correct option.Client Needs: Psychosocial Integrity。

They’re complaining that they’re receiving obsolete information from the Business Faculty’s network traffic broadcasts.What can you do to contain the Business Faculty’s broadcast while still keeping it connected to the internet and the enterprise services of the University? (Select all valid answer choices)A. Use half and full-duplex Ethernet on the Engineering Department LANB. Establish a VTP domain to minimize the obsolete trafficC. Change the switch IP address of the switchD. Create separate VLANs and subnets for the two departments and route between the twoE. Provide greater bandwidth to the Engineering Department LANF. Place the business department on a separate subnet and route between networks正确答案:DFD,F 解析:Explanation:In order to prevent the broadcast and link level multicast traffic separated between the departments, they need to be isolated at layer two. This can be accomplished in two ways. The first is to create separate VLANs and place each department into a different one. The second method would be to separate the two departments into two completely different networks, and route between them.Incorrect Answers:A. Mixing the use of half and full duplex will make no difference to the number of broadcasts sent.B. Trunking is only useful in networks that already contain VLANs.C. This will make no difference, as all users will still be contained within the same IP subnet.E. The amount of bandwidth involved will not have any impact on the amount of broadcasts that are sent and received.思科为何要开发专用的STP和RSTP扩展PVST+?( )8、A.通过优化根网桥的配置,提高会聚速度、优化数据流传输路径B.通过优化非根网桥的配置,提高会聚速度、优化数据流传输路径C.PVST+使得能够更迅速地丢弃非IP帧D.PVST+实际上是IEEE标准802.1w答案:A9、Which fields are included in the TCP header? (Choose three).A. Source PortB. Acknowledgement NumberC. Request NumberD. Destination AddressE. WindowF. Data正确答案:ABEA,B,E 解析:Explanation:TCPheader:Sourc e Port: 16 bits.Destination Port: 16 bits.Sequence Number: 32 bits.The sequence number of the first data byte in this segment. If the SYN bit is set, the sequence number is the initial sequence number and the first data byte is initial sequence number + 1.Acknowledgment Number: 32 bits.If the ACK bit is set, this field contains the value of the next sequence number the sender of the segment is expecting to receive. Once a connection is established this is always sent.Data Offset: 4 bits.The number of 32-bit words in the TCP header. This indicates where the data begins. The length of the TCP header is always a multiple of 32 bits.Reserved: 3 bits.Must be cleared to zero.ECN, Explicit Congestion Notification: 3 bits.Added in RFC 3168.Control Bits: 6 bits.Window: 16 bits, unsigned.The number of data bytes beginning with the one indicated in the acknowledgment field which the sender of this segment is willing to accept.Checksum: 16 bits.This is computed as the 16-bit one’s complement of the one’s complement sum of a pseudo header of information from the IP header, the TCP header, and the data, padded as needed with zero bytes at the end to make a multiple of two bytes.Urgent Pointer: 16 bits, unsigned.If the URG bit is set, this field points to the sequence number of the last byte in a sequence of urgent data.Options: 0 to 44 bytes.Options occupy space at the end of the TCP header. All options are included in the checksum. An option may begin on any byte boundary. The TCP header must be padded with zeros to make the header length a multiple of 32 bits.Data: Variable length.10、You need subnet a Ezonexam network segment. How many subnetworks and hosts are available per subnet if you apply a /28 mask to the 210.10.2.0 class C network?A. 30 networks and 6 hosts.B. 6 networks and 30 hosts.C. 8 networks and 32 hosts.D. 32 networks and 18 hosts.E. 16 networks and 14 hosts.F. None of the above正确答案:EE 解析:Explanation:A 28 bit subnet mask (11111111.11111111.11111111.11110000) applied to a class C network uses a 4 bits for networks, and leaves 4 bits for hosts. Using the 2n-2 formula, we have 24-2 (or 2x2x2x2-2) which gives us 14 for the number of hosts, and the number of networks is 24 = 16.Incorrect Answers:A. This would be the result of a /29 (255.255.255.248) network.B. This would be the result of a /27 (255.255.255.224) network.C. This is not possible, as we must subtract two from the subnets and hosts for the network and broadcast addresses.D. This is not a possible combination of networks and hosts.11、Show cdp interface命令是用于显示以下哪一项的()A.CDP的时间值和接口状态B.邻居路由器的接口配置C.邻居设备的IP地址D.CDP保持时间正确答案:A12、哪个命令用来设置Cisco设备串行接口的默认封装( )A.Router(config)encapsulation hdlcB.Router(config)encapsulation default hdlcC.Router(config-if)encapsulation hdlcD.Router(config-if)encapsulation ppp正确答案:C13、下图中如果允许192.168.1.0/24和10.0.0.0/8的网络之间通信,必须要配置的两条命令是什么( )A.A(config)iproute 10.0.0.0 255.0.0.0 172.16.40.2B.A(config)iproute 10.0.0.0 255.0.0.0 S0/0/0C.A(config)iproute 10.0.0.0 255.0.0.0 10.0.0.1D.B(config)iproute 192.168.1.0 255.255.255.0 172.16.40.1E.B(config)iproute 192.168.1.0 255.255.255.0 172.16.40.2F.Biproute 192.168.1.0 255.255.255.0 192.168.1.1正确答案:AD14、在启用IGRP协议时,所需要的参数是:( )A.网络掩码B.子网号C.自治系统号D.跳数正确答案:C15、请参见图示。
