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. Which type of hepatitis is transmitted via the fecal-oral route?

• A. Hepatitis A
• B. Hepatitis B
• C. Hepatitis C
• D. Hepatitis D

Correct answer: A

Rationale: Hepatitis A is the correct answer because it is transmitted via the fecal-oral route, often through contaminated food or water. Hepatitis B is transmitted through exposure to infectious blood, semen, and other body fluids, not through the fecal-oral route. Hepatitis C is transmitted through blood-to-blood contact, not via the fecal-oral route. Hepatitis D occurs only in individuals infected with Hepatitis B. Therefore, the correct choice for the type of hepatitis transmitted via the fecal-oral route is Hepatitis A.

3. Support systems during the grieving process include all of the following except:

• A. a despondent friend.
• B. a nurse.
• C. a social worker.
• D. a family member.

Correct answer: B

Rationale: During the grieving process, it is essential to have a support system in place. Options B, C, and D - a nurse, a social worker, and a family member, respectively, are individuals who can provide comfort, guidance, and practical assistance to someone who is grieving. However, a despondent friend, as stated in the question, is not an ideal choice for support during this period. A despondent friend is someone who is feeling extremely unhappy and discouraged, and may not have the emotional capacity to provide the needed support to a grieving individual. It is important for someone who is grieving to have support from individuals who can offer understanding, empathy, and strength, which a despondent friend may struggle to provide.

4. While making rounds at 3 am, the nurse discovers a small fire in a client's room. What should the nurse do first?

• A. Remove the client from the room immediately.
• B. Leave the client's room to obtain a fire extinguisher.
• C. Instruct a nurse tech to pull the fire alarm.
• D. Evacuate all clients from the unit.

Correct answer: A

Rationale: During a fire emergency, the priority is the safety of the individual in the room where the fire is located. Removing the client from the room immediately is the first step in the RACE acronym for fire safety: Rescue/Remove, Alarm, Contain, and Extinguish. This action ensures the client's safety before addressing the fire itself. Choice B is incorrect as leaving the client's room to obtain a fire extinguisher can delay the immediate removal of the client from the danger. Choice C is incorrect as pulling the fire alarm should be done after ensuring the client's safety. Choice D is incorrect as evacuating all clients from the unit should come after ensuring the safety of the individual in immediate danger.

5. Laboratory tests reveal the following electrolyte values for Mr. Smith: Na 135 mEq/L, Ca 8.5 mg/dL, Cl 102 mEq/L, and K 2.0 mEq/L. Which of the following values should the nurse report to the physician because of its potential risk to the client?

• A. Ca
• B. K
• C. Na
• D. Cl

Correct answer: B

Rationale: The correct answer is 'K.' Normal serum potassium levels range between 3.5 and 5.5 mEq/L. Mr. Smith's potassium level of 2.0 mEq/L is significantly below the normal range, indicating hypokalemia, which can lead to serious risks such as cardiac arrhythmias. The levels of sodium (Na), calcium (Ca), and chloride (Cl) are within normal ranges, so they do not pose an immediate risk to the client's health. Therefore, the nurse should report the low potassium level to the physician for prompt intervention.
