Question 1 of 5
A client is diagnosed with metastatic adenocarcinoma of the stomach. The physician prescribes mitomycin (Mutamycin) with other chemotherapeutic agents for palliative treatment. How mitomycin does exert its cytotoxic effects?
Correct Answer: A
Rationale: Mitomycin exerts its cytotoxic effects by forming cross-links between adjacent guanine residues in DNA, leading to inhibition of DNA synthesis. This mechanism disrupts the replication of cancer cells, ultimately inducing cell death. Mitomycin is an alkylating agent that primarily targets DNA, making it an effective treatment for certain types of cancers, such as adenocarcinoma of the stomach.
Question 2 of 5
A guest who is diabetic attended a bridal affair. The guest started to tremble and started to feel dizzy. Luckily a nurse is present. The best action for the nurse to take is to:
Correct Answer: D
Rationale: The best action for the nurse to take in this situation is to give the guest a glass of orange juice (Choice D). The guest is most likely experiencing hypoglycemia (low blood sugar) due to diabetes. Orange juice contains natural sugars that can help raise the guest's blood sugar levels quickly. Since the guest is feeling dizzy and trembling, providing a source of fast-acting sugar like orange juice is crucial in addressing the low blood sugar and preventing the situation from worsening. It is important to follow up with a source of longer-lasting carbohydrates and protein after the guest's blood sugar levels have stabilized.
Question 3 of 5
Which is a function of brown adipose tissue (BAT) in the newborn?
Correct Answer: D
Rationale: Brown adipose tissue (BAT) is specialized adipose tissue found in newborns and hibernating mammals, whose primary function is to generate heat through non-shivering thermogenesis. This heat generation is essential for maintaining body temperature in newborns, especially as they have a larger surface area-to-volume ratio, which results in greater heat loss compared to adults. BAT produces heat by metabolizing stored lipids and disrupting the normal process of cellular respiration, leading to the production of heat instead of ATP. The heat generated by BAT is then distributed throughout the body to help maintain a stable core body temperature in newborns, who are not yet able to regulate their body temperature as effectively as adults.
Question 4 of 5
Which of the following blood products is most likely to be given to Joel?
Correct Answer: A
Rationale: Joel most likely requires Factor VIII concentrate. Factor VIII deficiency is characteristic of hemophilia A, which is a condition where there is a deficiency in clotting factor VIII. Treatment for hemophilia A involves replacing the missing Factor VIII through Factor VIII concentrate infusions to assist in blood clotting. Fresh frozen plasma and Factor II, VII, IX, X complex are not specific treatments for Factor VIII deficiency.
Question 5 of 5
Which of the ff. problems during the immediate postoperative course ff. lumbar microdiskectomy should be reported to the physician immediately?
Correct Answer: B
Rationale: Inability to move the affected leg after a lumbar microdiskectomy could indicate a serious complication such as nerve damage or postoperative hematoma putting pressure on the nerves. This is a critical issue that should be reported to the physician immediately for proper evaluation and management to prevent further complications or permanent damage. The other options, such as incisional pain, bleeding on the dressing, or muscle spasm, are common postoperative issues that may not require immediate medical attention unless they are severe or persistent.
