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. A 27-year-old woman has delivered twins in the OB unit. The patient develops a condition of 5-centimeter diastasis recti abdominis. Which of the following statements is the most accurate when instructing the patient?

• A. Avoid sit-ups to prevent worsening the condition.
• B. Surgery is not always necessary for this condition.
• C. Guarding the abdominal region is important at this time.
• D. Antibiotics are not needed for diastasis recti abdominis.

Correct answer: C

Rationale: After experiencing diastasis recti abdominis, it is crucial for the patient to protect and guard the abdominal region to facilitate healing. Choice A is correct since avoiding sit-ups is important to prevent worsening the condition by increasing intra-abdominal pressure. Choice B is accurate as not all cases of diastasis recti abdominis require surgery; conservative management is often effective. Choice D is also correct as antibiotics are not indicated for diastasis recti abdominis since it is a separation of the abdominal muscles and not an infectious condition.

3. One of the major functions of the kidneys in maintaining normal fluid balance is:

• A. the manufacture of antidiuretic hormone.
• B. the regulation of calcium and phosphate balance.
• C. the regulation of the pH of the extracellular fluid.
• D. the control of aldosterone levels.

Correct answer: C

Rationale: The correct answer is 'the regulation of the pH of the extracellular fluid.' The kidneys play a crucial role in maintaining normal fluid balance by regulating extracellular fluid and osmolarity through selective retention and excretion of fluids. Additionally, they regulate the pH of the extracellular fluid by retaining hydrogen ions and excreting metabolic wastes and toxic substances. Choice A is incorrect because antidiuretic hormone (ADH) is manufactured by the pituitary gland, not the kidneys. Choice B is incorrect as the regulation of calcium and phosphate balance is primarily controlled by the parathyroid gland. Choice D is incorrect as aldosterone levels are controlled by the adrenal glands, not the kidneys.

4. The power a healthcare professional exerts when working to accomplish goals and effect change in an agency or policy is considered what type of power?

• A. political
• B. personal
• C. positional
• D. professional

Correct answer: A

Rationale: Political power is the correct answer in this scenario. It stems from the ability to navigate systems, agencies, or policies to bring about change. Personal power is related to charisma and self-confidence in informal leadership roles. Positional power comes from holding a specific authority in a formal position. Professional power is derived from expertise in a particular area of practice. Therefore, in the context of effecting change in an agency or policy, political power is the most relevant type of power.

5. A nurse reviewed the arterial blood gas reading of a 25-year-old male. The nurse should be able to conclude the patient is experiencing which of the following conditions?

• A. metabolic acidosis
• B. respiratory acidosis
• C. metabolic alkalosis
• D. respiratory alkalosis

Correct answer: D

Rationale: The correct answer is respiratory alkalosis. In respiratory alkalosis, there is an elevated pH and low carbon dioxide levels (PaCO2 < 35 mmHg). In the given arterial blood gas reading, the patient's pH is 7.41 (within normal range), PaCO2 is 29 mmHg (below normal range), indicating respiratory alkalosis. The bicarbonate level is normal (25 mEq/l), ruling out metabolic acidosis or alkalosis. The low PaO2 (54 mmHg) may indicate hypoxemia, but it is not directly related to the acid-base disorder being assessed. Metabolic acidosis (choice A) is characterized by low pH and low bicarbonate levels, which are not present in this case. Respiratory acidosis (choice B) is indicated by low pH and high PaCO2 levels, which also do not match the provided data. Metabolic alkalosis (choice C) is defined by high pH and high bicarbonate levels, which are not seen in this scenario.
