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. The nurse is caring for a client with hyperemesis gravidarum. What is the most likely electrolyte imbalance?

• A. Hypocalcemia
• B. Hypomagnesemia
• C. Hyponatremia
• D. Hypokalemia

Correct answer: D

Rationale: In hyperemesis gravidarum, where the client experiences severe nausea and vomiting, the most likely electrolyte imbalance is hypokalemia. Potassium is abundant in the stomach, and excessive vomiting leads to potassium loss. Hypocalcemia (Choice A) is not typically associated with hyperemesis gravidarum. Hypomagnesemia (Choice B) and Hyponatremia (Choice C) are less likely to occur compared to hypokalemia in this condition.

3. What task should the RN perform first?

• A. Changing a burn dressing that is scheduled every four hours.
• B. Doing pinsite care on a client in skeletal traction ordered TID.
• C. Teaching a newly diagnosed diabetic about diet and exercise.
• D. Assessing a newly admitted client.

Correct answer: D

Rationale: The correct answer is to assess a newly admitted client first. When a client is newly admitted, it is crucial to perform an assessment promptly. The initial assessment and establishment of a care plan should be completed within a specific timeframe to ensure the client's needs are met effectively. Choices A, B, and C involve important tasks but should be prioritized after the initial assessment of the newly admitted client to ensure timely and appropriate care delivery. Changing a burn dressing (Choice A) and doing pinsite care on a client in skeletal traction (Choice B) are time-sensitive tasks but can be safely delayed briefly to conduct the initial assessment. Teaching a newly diagnosed diabetic about diet and exercise (Choice C) is important for the client's long-term care but can be scheduled after the immediate needs assessment of the newly admitted client.

4. When caring for a client with a possible diagnosis of placenta previa, which of the following admission procedures should the nurse omit?

• A. perineal shave
• B. enema
• C. urine specimen collection
• D. blood specimen collection

Correct answer: B

Rationale: The correct answer is 'enema.' Administering an enema to a client with placenta previa can dislodge the placenta, leading to an increased risk of bleeding and complications. It is crucial to avoid any interventions that may disrupt the placenta's positioning. Collecting urine and blood specimens are necessary for diagnostic purposes and monitoring, while a perineal shave is a routine procedure that does not pose a risk to the client with placenta previa.

5. When assessing a client in the Emergency Department whose membranes have ruptured, the nurse notes that the fluid is a greenish color. What is the cause of this greenish coloration?

• A. blood
• B. meconium
• C. hydramnios
• D. caput

Correct answer: B

Rationale: The correct answer is B: meconium. Greenish amniotic fluid passed when the fetus is in a cephalic (head) presentation might indicate fetal distress. A fetus in the breech presentation passes meconium due to compression on the intestinal tract. Choice A, blood, is incorrect as blood in the amniotic fluid would present as a different color. Choice C, hydramnios, refers to an excess of amniotic fluid and would not cause the greenish coloration. Choice D, caput, is swelling of a newborn's scalp and is not related to the color of the amniotic fluid.
