1. Round off these numbers to the nearest tenth:

A. 5.5778 = 5.6, 1.027 = 1.0, 62.999 = 63, 55.123 = 55.1, 96.676 = 96.7
B. 5.5778 = 5.6, 1.027 = 1.0, 62.999 = 63, 55.123 = 55.1, 96.676 = 96.7
C. 5.5778 = 5.6, 1.027 = 1.0, 62.999 = 63, 55.123 = 55.1, 96.676 = 96.7
D. 5.5778 = 5.6, 1.027 = 1.0, 62.999 = 63, 55.123 = 55.1, 96.676 = 96.7

Correct answer: B

Rationale: The correct answer is B. When rounding off to the nearest tenth, 1.027 becomes 1.0 because the digit in the hundredth's place is less than 5. For the other numbers, they are rounded correctly to the nearest tenth: 5.5778 = 5.6, 62.999 = 63, 55.123 = 55.1, 96.676 = 96.7. Therefore, option B is the most accurate in rounding off these numbers to the nearest tenth. Choices A, C, and D are incorrect as they do not round 1.027 to 1.0 as required when rounding to the nearest tenth.

2. Diabetes insipidus is the result of:

A. A diet high in sugar and carbohydrates.
B. A complicated pregnancy.
C. A disorder of the pancreas.
D. A disorder of the pituitary gland.

Correct answer: D

Rationale: Diabetes insipidus is caused by a disorder of the pituitary gland affecting ADH regulation. This disorder results in the decreased production or release of antidiuretic hormone (ADH), leading to the inability of the kidneys to concentrate urine properly. Choices A, B, and C are incorrect as they do not relate to the underlying cause of diabetes insipidus.

3. Which of the following is considered an internal disaster?

A. A patient fall
B. The massive spread of pneumonia
C. A computer hacking episode
D. Unexpected staff absences due to illness

Correct answer: C

Rationale: A computer hacking episode is considered an internal disaster as it disrupts the internal operations of the healthcare facility, compromising data security and potentially impacting patient care. Choices A, B, and D do not directly relate to internal disasters in a healthcare setting. A patient fall is a patient safety issue, the massive spread of pneumonia is a public health concern, and unexpected staff absences due to illness may affect staffing levels but are not typically classified as internal disasters.

4. The doctor has ordered 20 cc per hour of normal saline intravenously for your pediatric patient. You will be using pediatric intravenous tubing that delivers 60 cc per drop. How many drops per minute will you administer using this pediatric intravenous set?

A. 30 drops per minute
B. 25 drops per minute
C. 20 drops per minute
D. 22 drops per minute

Correct answer: C

Rationale: To calculate the drops per minute, first convert the ordered amount to drops per minute. 20 cc per hour equals 20 drops per hour with 60 cc per drop tubing, which is equivalent to 20 drops per hour * 60 cc per drop = 1200 drops per hour. To find drops per minute, divide 1200 by 60 (minutes in an hour), which equals 20 drops per minute. Therefore, the correct answer is 20 drops per minute. Choices A, B, and D are incorrect as they do not reflect the correct calculation based on the provided information.

5. Clients with type 1 diabetes may require which of the following changes to their daily routine during periods of infection?

A. No change
B. Less insulin
C. More insulin
D. Oral antidiabetic agents

Correct answer: C

Rationale: During periods of infection, clients with type 1 diabetes may require more insulin to manage the increased blood glucose levels caused by stress and illness. Insulin needs often rise during infections due to the body's increased resistance to the effects of insulin. Therefore, increasing insulin doses is crucial to maintain blood glucose control. Choices A, B, and D are incorrect. Option A ('No change') is inaccurate because during infections, insulin requirements typically increase. Option B ('Less insulin') is incorrect as the body's increased insulin resistance during infections usually necessitates higher insulin doses. Option D ('Oral antidiabetic agents') is not suitable for type 1 diabetes management as these medications are primarily used for type 2 diabetes.
