1. The test used to differentiate sickle cell trait from sickle cell disease is:

Correct answer: D

Rationale: The correct test to differentiate between sickle cell trait and sickle cell disease is hemoglobin electrophoresis. This test separates different types of hemoglobin based on their electrical charge, allowing for the identification of specific hemoglobin variants like HbS in sickle cell disease. Sickle cell preparation and Sickledex are not specific tests for this differentiation. While a peripheral smear can show sickle cells, it does not provide a definitive differentiation between the trait and the disease as it doesn't identify the specific hemoglobin variant present.

2. The chemotherapeutic agent 5-fluorouracil (5-FU) is ordered for a client as an adjunct measure to surgery. Which statement about chemotherapy is true?

Correct answer: B

Rationale: The correct answer is that chemotherapy is a systemic treatment affecting both tumor and normal cells. 5-FU, as an antimetabolic drug, inhibits DNA synthesis and interferes with cell replication systemically. It affects all rapidly growing cells, including malignant and normal ones. This drug is used as adjuvant therapy for various cancers. Choice A is incorrect because chemotherapy affects both tumor and normal cells, not just tumor cells. Choice C is incorrect as chemotherapy has been proven effective in treating cancer. Choice D is incorrect because chemotherapy often causes side effects like bone marrow depression, anorexia, stomatitis, nausea, and vomiting.

3. Which type of cells secrete insulin?

Correct answer: B

Rationale: Beta cells are responsible for secreting insulin. Insulin is produced by beta cells in the pancreas and plays a crucial role in regulating blood sugar levels. Alpha cells secrete glucagon, not insulin (Choice A). CD4 cells are a type of immune cell that helps coordinate the immune response (Choice C). Helper cells are a type of immune cell that aids in activating other immune cells (Choice D). Therefore, the correct answer is beta cells.

4. Which is an example of a sentinel event?

Correct answer: D

Rationale: Yes! A sentinel event is an unexpected occurrence causing death or serious injury. In this case, a client who was scheduled for knee replacement surgery but had an above-the-knee amputation performed instead represents a sentinel event as it resulted in serious harm that was not intended. The other choices do not meet the criteria for a sentinel event. Choice A describes a natural progression for a terminally ill client, choice B shows an incidental finding from a test, and choice C involves a preventable fall leading to an injury but not a sentinel event.

5. Why must the nurse be careful not to cut through or disrupt any tears, holes, bloodstains, or dirt present on the clothing of a client who has experienced trauma?

Correct answer: C

Rationale: In cases of trauma, the clothing of a client can hold crucial evidence that may have legal implications. It is essential for the nurse to avoid cutting through or disrupting any tears, holes, bloodstains, or dirt present on the clothing to preserve this potential evidence. The correct answer highlights the legal importance of preserving the clothing for potential legal implications. Choice B is related but does not emphasize the legal aspect explicitly. Choice C is vague in mentioning further investigation without specifying the legal significance. Choice D focuses more on forensic analysis rather than the legal implications of preserving the clothing.
