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 client comes to the clinic for assessment of his physical status and guidelines for starting a weight-reduction diet. The client's weight is 216 pounds and his height is 66 inches. The nurse identifies the BMI (body mass index) as:

• A. Within normal limits, so a weight-reduction diet is unnecessary.
• B. Lower than normal, so education about nutrient-dense foods is needed.
• C. Indicating obesity because the BMI is 35.
• D. Indicating overweight status because the BMI is 27.

Correct answer: C

Rationale: Obesity is defined by a BMI of 30 or more with no co-morbid conditions. Body Mass Index (BMI) is calculated by utilizing a chart or nomogram that plots height and weight. In this case, the client's BMI is calculated as 35, indicating obesity. A BMI of 27 falls within the overweight range, not obesity (which starts at 30). Choices A and B are incorrect because a BMI of 35 indicates obesity, not normal limits or being lower than normal. Therefore, the correct answer is C, indicating obesity based on the BMI calculation.

3. A 64-year-old Alzheimer's patient has exhibited excessive cognitive decline resulting in harmful behaviors. The physician orders restraints to be placed on the patient. Which of the following is the appropriate procedure?

• A. Secure the restraints to the bed rails on all extremities.
• B. Notify the physician that restraints have been placed properly.
• C. Communicate with the patient and family the need for restraints.
• D. Position the head of the bed at a 45-degree angle.

Correct answer: C

Rationale: In cases where restraints are considered necessary for a patient, it is crucial to communicate effectively with both the patient and their family about the reasons for this decision. This helps ensure that all parties involved understand the necessity of restraints and are informed about the potential risks and benefits. Option A, securing restraints to the bed rails on all extremities, is not appropriate as it does not involve proper communication or ethical considerations. Option B, notifying the physician that restraints have been placed properly, overlooks the importance of patient and family involvement in decision-making. Option D, positioning the head of the bed at a 45-degree angle, is unrelated to the use of restraints and does not address the situation at hand.

4. A nurse assesses an 83-year-old female's venous ulcer for the second time that is located near the right medial malleolus. The wound is exhibiting purulent drainage, and the patient has limited mobility in her home. Which of the following is the best course of action?

• A. Encourage warm water soaks to the right foot.
• B. Notify the case manager of the purulent drainage.
• C. Determine the patient's pulse in the right ankle.
• D. Recommend increased activity to reduce the purulent drainage.

Correct answer: A

Rationale: The correct course of action is to encourage warm water soaks to the right foot. This can help promote wound healing and alleviate discomfort. Before recommending increased activity or notifying additional team members, it is crucial to assess arterial blood flow by determining the patient's pulse in the right ankle. Poor arterial blood flow could worsen the condition, making increased activity inappropriate. While notifying the case manager of purulent drainage is important, addressing the wound care directly should be the primary focus at this stage.

5. Which of the following conditions places a client at risk for developing cirrhosis?

• A. Type I diabetes
• B. Alcoholism
• C. Leukemia
• D. Glaucoma

Correct answer: B

Rationale: Alcoholism places a client at risk for developing cirrhosis due to the liver damage caused by excessive alcohol consumption. Type I diabetes, leukemia, and glaucoma are not directly associated with cirrhosis. While diabetes can lead to other health complications, it does not directly cause cirrhosis. Leukemia is a type of blood cancer that does not affect the liver in a way that leads to cirrhosis. Glaucoma is an eye condition that has no direct link to cirrhosis.
