Nursing Elites

1. Which type of cells secrete insulin?

• A. alpha cells
• B. beta cells
• C. CD4 cells
• D. helper cells

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.

2. 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?

• A. The clothing is the property of another and must be treated with care.
• B. Such care facilitates repair and salvage of the clothing.
• C. The clothing of a trauma victim is potential evidence with legal implications.
• D. Such care decreases trauma to the family members receiving the clothing.

Correct answer: C

Rationale: The correct answer is C. Trauma in any client, living or dead, has potential legal and/or forensic implications. Clothing, patterns of stains, and debris are sources of potential evidence and must be preserved. Nurses must be aware of state and local regulations that require mandatory reporting of cases of suspected child and elder abuse, accidental death, and suicide. Each Emergency Department has written policies and procedures to assist nurses and other health care providers in making appropriate reports. Physical evidence is real, tangible, or latent matter that can be visualized, measured, or analyzed. Emergency Department nurses can be called on to collect evidence. Health care facilities have policies governing the collection of forensic evidence. The chain of evidence custody must be followed to ensure the integrity and credibility of the evidence. The chain of evidence custody is the pathway that evidence follows from the time it is collected until it has served its purpose in the legal investigation of an incident. Choices A, B, and D are incorrect because they do not address the crucial aspect of preserving potential evidence with legal implications that may be present on the clothing of a trauma victim.

3. A 93-year-old female with a history of Alzheimer's Disease gets admitted to an Alzheimer's unit. The patient has exhibited signs of increased confusion and limited stability with gait. Moreover, the patient is refusing to use a w/c. Which of the following is the most appropriate course of action for the nurse?

• A. Recommend the patient remain in her room at all times.
• B. Recommend family members bring pictures to the patient's room.
• C. Recommend a speech therapy consult to the doctor.
• D. Recommend the patient attempt to walk pushing the w/c for safety.

Correct answer: B

Rationale: For a 93-year-old female with Alzheimer's Disease exhibiting signs of increased confusion and limited stability with gait, recommending family members to bring pictures to the patient's room is the most appropriate course of action. Visual stimulation in the form of pictures may help decrease signs of confusion and provide comfort to the patient. Option A is incorrect as isolating the patient in her room at all times may worsen her condition by further limiting stimulation and interaction. Option C is incorrect as speech therapy may not directly address the current issues of confusion and gait instability. Option D is incorrect as pushing a wheelchair may not be safe for the patient if she is refusing to use it, potentially leading to falls or further distress.

4. What is the best lab test to diagnose disseminated intravascular coagulation (DIC)?

• A. platelet count
• B. prothrombin time (PT)
• C. partial thromboplastin time (PTT)
• D. D-dimer

Correct answer: D

Rationale: The best lab test to diagnose disseminated intravascular coagulation (DIC) is the D-dimer test. In DIC, numerous small clots form throughout the body and are rapidly broken down. D-dimer measures a specific fibrin split product and is the most specific test for DIC. Platelet count (Choice A) is decreased in DIC due to consumption, but it is not specific for diagnosing DIC. Prothrombin time (PT - Choice B) and partial thromboplastin time (PTT - Choice C) are both elevated in DIC because clotting factors have been used up, but they are not specific for DIC as they can be elevated in other conditions as well.

5. A client, age 28, was recently diagnosed with Hodgkin's disease. After staging, therapy is planned to include combination radiation therapy and systemic chemotherapy with MOPP"?nitrogen mustard, vincristine (Onconvin), prednisone, and procarbazine. In planning care for this client, the nurse should anticipate which of the following side effects to contribute to a sense of altered body image?

• A. Cushingoid appearance
• B. Alopecia
• C. Temporary or permanent sterility
• D. Pathologic fractures

Correct answer: B

Rationale: The correct answer is B: alopecia. Chemotherapy drugs like vincristine and nitrogen mustard commonly cause hair loss (alopecia), which can significantly impact body image. While a Cushingoid appearance can be a side effect of long-term steroid use, it is not typically associated with the chemotherapy regimen mentioned. Temporary or permanent sterility can result from chemotherapy, affecting fertility but not directly contributing to altered body image. Pathologic fractures are not commonly linked to Hodgkin's disease or its treatment, unlike alopecia which is a well-known side effect.
