Which of the following isoenzymes is elevated in a client who has had a myocardial infarction?
- A. CPK-BB
- B. CPK-MM
- C. CPK-MB
- D. CPK-MI
Correct Answer: C
Rationale: CPK-MB is the correct answer as it is elevated in clients who have had a myocardial infarction. CPK-BB is elevated in clients with brain damage, and CPK-MM is elevated in clients with skeletal muscle damage. CPK-MI, mentioned in the rationale, does not exist, making it an incorrect choice.

To assess a client's ankle ROM, which ROM exercises should the nurse have them perform?
- A. flexion, extension, hyperextension
- B. flexion, extension, abduction, adduction
- C. external rotation, internal rotation
- D. extension, flexion, inversion, eversion
Correct Answer: D
Rationale: The correct answer is extension, flexion, inversion, and eversion. These exercises help assess the full range of motion of the ankles. Flexion and extension evaluate the bending and straightening movements of the ankle joint, respectively. Inversion and eversion assess the inward and outward movements of the foot at the ankle joint. Hyperextension, abduction, and adduction are not specific movements of the ankle joint, making choices A and B incorrect. External and internal rotation are movements more related to joints like the hip or shoulder, not the ankle, making choice C incorrect.
What action should the emergency triage nurse take upon receiving the history that a client has a severe cough, fever, night sweats, and body wasting?
- A. Place the client in isolation until further assessment is completed.
- B. Seclude the client from other clients and visitors.
- C. Perform no intervention until test results confirm a diagnosis.
- D. Don personal protective equipment immediately.
Correct Answer: B
Rationale: The correct action for the emergency triage nurse to take upon receiving the history that a client has a severe cough, fever, night sweats, and body wasting is to seclude the client from other clients and visitors. These symptoms are suggestive of tuberculosis, a highly infectious disease. By secluding the client, the nurse can prevent the potential spread of the infection to others. Donning personal protective equipment, including gown, gloves, and a mask, is crucial when providing care to the client, but the immediate priority is to prevent the spread of infection by isolating the client. Placing the client in isolation until further assessment is completed ensures that the client is kept away from others until a proper diagnosis and treatment plan can be established, reducing the risk of transmission. Performing no intervention until test results confirm a diagnosis is inappropriate as immediate isolation is necessary in suspected cases of highly infectious diseases like tuberculosis.
During surgery, it is found that a client with adenocarcinoma of the rectum has positive peritoneal lymph nodes. What is the next most likely site of metastasis?
- A. brain
- B. bone
- C. liver
- D. mediastinum
Correct Answer: C
Rationale: In cases of adenocarcinoma of the rectum with positive peritoneal lymph nodes, the most likely site of metastasis is the liver. Colon tumors commonly spread through the lymphatics and portal vein to the liver. While metastasis to the brain, bone, or mediastinum is possible, the liver is typically the first to be affected due to the anatomical pathways involved in colorectal cancer metastasis. Therefore, the correct answer is the liver. Metastasis to the brain, bone, or mediastinum would be less likely at this stage of colorectal cancer progression.
The graduate licensed practical nurse is assigned to care for the client on ventilator support, pending organ donation. Which goal should receive priority?
- A. Maintain the client's systolic blood pressure at 70mmHg or greater
- B. Maintain the client's urinary output greater than 300cc per hour
- C. Maintain the client's body temperature above 33°F rectal
- D. Maintain the client's hematocrit below 30%
Correct Answer: A
Rationale: When caring for a client on ventilator support pending organ donation, maintaining the systolic blood pressure at 70mmHg or greater is crucial to ensure a proper blood supply to the donor organ. This goal is a priority to maintain the viability of the organ for donation. Choices B, C, and D are incorrect because they are unnecessary and not directly related to the immediate goal of organ donation. Maintaining urinary output, body temperature, or hematocrit levels are not the primary concerns in this situation.
A client has been placed in isolation because he is diagnosed with a contagious illness. The nurse should be aware that:
- A. Linens from the client's bed should be double-bagged.
- B. Meals should be served on washable dishes.
- C. Extensive isolation rarely causes psychological problems.
- D. Paper trays and plastic utensils do not prevent disease transmission.
Correct Answer: A
Rationale: Isolation techniques are used to prevent or limit the spread of infection. Special handling of articles and linens soiled by any body fluid is essential. Linens should be placed in impervious bags before being removed from the client's bedside to prevent exposure of personnel and contamination of the environment. Double-bagging is required if the outside of the bag becomes contaminated. This practice ensures that potentially infectious materials are properly contained and disposed of. Choices B, C, and D are incorrect because the focus in this scenario is on proper handling and disposal of soiled linens to prevent the spread of infection, not on serving meals, psychological effects of isolation, or the use of paper trays and plastic utensils.
