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. What is most important for the healthcare professional to do prior to initiating peritoneal dialysis?

• A. Aspirate to check placement
• B. Ensure the client voids
• C. Irrigate the catheter to maintain patency
• D. Warm the fluids

Correct answer: D

Rationale: The correct answer is to warm the fluids. Warming the dialysis fluids is crucial before initiating peritoneal dialysis to prevent abdominal discomfort and promote vasodilation, which helps in achieving good exchange in the peritoneum. Aspirating to check placement (Choice A) is not typically necessary before initiating peritoneal dialysis. Ensuring the client voids (Choice B) is not directly related to the procedure of peritoneal dialysis. Irrigating the catheter to maintain patency (Choice C) is usually done as part of routine care but is not specifically required prior to initiating peritoneal dialysis. Therefore, the most important action to take before starting peritoneal dialysis is to warm the fluids.

3. Which of the following symptoms is most characteristic of a client with lung cancer?

• A. exertional dyspnea
• B. persistent changing cough
• C. air hunger; dyspnea
• D. cough with night sweats

Correct answer: B

Rationale: The most characteristic symptom of lung cancer is a persistent changing cough. This cough may worsen over time and may produce blood-tinged sputum. Exertional dyspnea (Choice A) is more common in chronic obstructive pulmonary disease (COPD) due to airway obstruction. Air hunger and dyspnea (Choice C) are more typical of conditions like asthma. Cough with night sweats (Choice D) is commonly associated with tuberculosis rather than lung cancer.

4. Paula is a 32-year-old woman seeking evaluation and treatment for major depressive symptoms. A major nursing priority during the assessment process includes which of the following?

• A. meaning of current stressors
• B. possibility of self-harm
• C. motivation to participate in treatment
• D. presence of alcohol or other drug use

Correct answer: B

Rationale: The correct answer is to consider the possibility of self-harm during the assessment process. This is crucial because unless the client is first assessed for self-harm or suicide potential, the necessary degree of vigilance in the client's environment may not be observed. While understanding the meaning of current stressors is important for treatment planning, ensuring the client's safety takes precedence. Motivation to participate in treatment and the presence of alcohol or other drug use are also important aspects to assess but ensuring the client's safety is the top priority in this scenario.

5. A healthcare professional is reviewing a patient's current Lithium levels. Which of the following values is outside the therapeutic range?

• A. 1.0 mEq/L
• B. 1.1 mEq/L
• C. 1.2 mEq/L
• D. 1.3 mEq/L

Correct answer: D

Rationale: The correct answer is 1.3 mEq/L. The therapeutic range for Lithium levels typically falls between 0.6 to 1.2 mEq/L. Values below or above this range can lead to suboptimal treatment outcomes or toxicity. Choices A, B, and C are within the therapeutic range of 1.0-1.2 mEq/L, making them appropriate levels for patient care.
