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 client has been taking divalproex (Depakote) for the management of bipolar disorder. The nurse should give priority to monitoring which laboratory test?

• A. Alanine aminotransferase (ALT)
• B. Serum glucose
• C. Serum creatinine
• D. Serum electrolytes

Correct answer: A

Rationale: The correct answer is Alanine aminotransferase (ALT). Monitoring ALT levels is crucial when a patient is taking divalproex (Depakote) due to the risk of drug-induced hepatitis. Elevated ALT levels indicate liver damage or disorders, which can be a side effect of Depakote. Serum glucose (choice B) is not the priority for monitoring in this case, as the medication does not directly affect glucose levels. Serum creatinine (choice C) is not the most relevant test to monitor for Depakote use; it primarily assesses kidney function. Serum electrolytes (choice D) are important but do not take precedence over monitoring ALT levels when a patient is on Depakote.

3. A client arrives in the emergency department after severely lacerating the left hand with a knife. HR 96, BP 150/88, R36. The client is extremely anxious and crying uncontrollably. Based on this assessment, the nurse anticipates that this client would be in which acid-base imbalance?

• A. Respiratory acidosis
• B. Respiratory alkalosis
• C. Metabolic acidosis
• D. Metabolic alkalosis

Correct answer: B

Rationale: The correct answer is respiratory alkalosis. Hyperventilation due to anxiety, pain, shock, severe infection, fever, or liver failure can lead to respiratory alkalosis. In this scenario, the client is extremely anxious and crying uncontrollably, indicating an increased respiratory rate and CO2 loss. Respiratory acidosis (choice A) is incorrect as it is characterized by an increase in CO2 levels, not a loss. Metabolic acidosis (choice C) involves a decrease in blood pH due to an accumulation of acids or loss of bicarbonate, which is not the case here. Metabolic alkalosis (choice D) results from excess bicarbonate or a loss of acids, not from increased CO2 loss due to hyperventilation.

4. Herbal therapy has several indications for use. Primarily, herbal therapy is:

• A. used to treat many common complaints and diseases.
• B. used to promote certain types of low-carb diets.
• C. used as an adjunct to medications.
• D. used to create a diet without salt and carbohydrates.

Correct answer: A

Rationale: The correct answer is A: 'used to treat many common complaints and diseases.' Herbal therapy is commonly used to address a variety of health issues and ailments by utilizing natural remedies derived from plants. Choices B, C, and D are incorrect because herbal therapy's primary purpose is not to promote specific diets, act as an adjunct to medications, or create specific dietary restrictions, but rather to provide alternative treatment options for various health conditions.

5. A client receiving drug therapy with furosemide and digitalis requires careful observation and care. In planning care for this client, the nurse should recognize that which of the following electrolyte imbalances is most likely to occur?

• A. hyperkalemia
• B. hypernatremia
• C. hypokalemia
• D. hypomagnesemia

Correct answer: C

Rationale: When a client is receiving drug therapy with furosemide and digitalis, the nurse should anticipate the development of hypokalemia due to the potassium-wasting effects of furosemide. Hypokalemia can potentiate digitalis toxicity. While hyperkalemia is a concern with some medications, it is not typically associated with furosemide and digitalis. Furosemide can lead to hyponatremia, not hypernatremia, due to its diuretic effect. Hypomagnesemia, though a possible imbalance, is not the most likely to occur in this scenario as furosemide and digitalis are more commonly associated with hypokalemia.
