1. Which hormone is secreted by the Islets of Langerhans?

• A. Progesterone
• B. Testosterone
• C. Insulin
• D. Hemoglobin

Correct answer: C

Rationale: Insulin is the correct answer. It is the hormone secreted by the Islets of Langerhans in the pancreas. These specialized cells regulate blood sugar levels by releasing insulin in response to high blood glucose levels. Insulin aids in glucose absorption by cells, lowering blood sugar levels. Progesterone, testosterone, and hemoglobin are not secreted by the Islets of Langerhans and do not play a role in blood sugar regulation.

2. What is the most common cause of dementia among elderly persons?

• A. Parkinson’s disease
• B. Multiple sclerosis
• C. Amyotrophic lateral sclerosis (Lou Gehrig’s disease)
• D. Alzheimer’s disease

Correct answer: D

Rationale: Alzheimer’s disease is the most common cause of dementia among elderly persons. It is a progressive neurodegenerative disorder that affects memory, thinking, and behavior. While Parkinson’s disease, multiple sclerosis, and amyotrophic lateral sclerosis are serious conditions, they are not typically associated with dementia in the same way Alzheimer’s disease is. Therefore, the correct answer is D.

3. When applying Nagele's rule, a healthcare professional is estimating a client's expected date of delivery based on their last menstrual period, which began on April 12th. What date should the healthcare professional determine to be the client's expected delivery date? (Use mmdd format.)

• A. 119
• B. 121
• C. 115
• D. 122

Correct answer: A

Rationale: To calculate the expected delivery date using Nagele's rule, begin by subtracting 3 months from the first day of the last menstrual period (April 12th), which results in January 12th. Then, add 7 days. Therefore, the expected delivery date would be January 19th (0119). This calculation method helps healthcare professionals estimate the client's due date.

4. A client is experiencing preterm contractions and dehydration. Which of the following statements should the nurse make?

• A. Dehydration is treated with calcium supplements.
• B. Dehydration can increase the risk of preterm labor.
• C. Dehydration is associated with gastroesophageal reflux.
• D. Dehydration is caused by decreased hemoglobin and hematocrit.

Correct answer: B

Rationale: Dehydration can lead to an imbalance in electrolytes and cause uterine irritability, potentially leading to preterm contractions. It is essential for the nurse to educate the client on the importance of adequate hydration to reduce the risk of preterm labor. The statement 'Dehydration can increase the risk of preterm labor' directly addresses the client's condition and provides relevant information for their understanding and management of the situation.

5. A healthcare professional is reviewing the laboratory results of a client who has rheumatoid arthritis. Which of the following findings should the healthcare professional report to the provider?

• A. WBC count 8,000/mm³
• B. Platelets 150,000/mm³
• C. Aspartate aminotransferase 10 units/L
• D. Erythrocyte sedimentation rate 75 mm/hr

Correct answer: D

Rationale: In clients with rheumatoid arthritis, an elevated erythrocyte sedimentation rate (ESR) is a common finding and indicates inflammation in the body. A high ESR value suggests active disease activity and potential joint damage. Therefore, the healthcare professional should report an ESR of 75 mm/hr to the provider for further evaluation and management of the client's rheumatoid arthritis.
