1. What type of diet is appropriate for a client with chronic cirrhosis?

• A. High calorie, low protein
• B. High protein, high calorie
• C. Low fat, low sodium
• D. High calorie, low sodium

Correct answer: A

Rationale: The correct diet for a client with chronic cirrhosis is high calorie, low protein. Cirrhosis can lead to impaired protein metabolism, making it essential to limit protein intake. High-calorie foods help meet the client's energy needs. Choice B (High protein, high calorie) is incorrect because high protein intake can worsen hepatic encephalopathy. Choice C (Low fat, low sodium) is not the most appropriate diet for cirrhosis as the focus should be on calories and protein. Choice D (High calorie, low sodium) does not address the need to restrict protein intake, which is crucial in cirrhosis.

2. How can light therapy be effective?

• A. overcoming weight problems.
• B. helping with allergies.
• C. use in alternative medical treatments.
• D. working with sleep patterns.

Correct answer: D

Rationale: Light therapy can be effective in treating problems associated with sleep patterns, stress, moods, jaundice in newborns, and seasonal affective disorders. While light therapy is not typically used for overcoming weight problems or helping with allergies, it is specifically known for its benefits in regulating sleep patterns. Therefore, the correct answer is 'working with sleep patterns.' Choices A, B, and C are incorrect as light therapy is not commonly utilized for overcoming weight problems, helping with allergies, or as a general alternative medical treatment.

3. Chemotherapeutic agents often produce a degree of myelosuppression including leukopenia. Leukopenia does not present immediately but is delayed several days or weeks because:

• A. the client's hemoglobin and hematocrit are normal.
• B. red blood cells are affected first.
• C. folic acid levels are normal.
• D. the current white cell count is not affected by chemotherapy.

Correct answer: D

Rationale: Leukopenia does not present immediately after chemotherapy because time is required to clear circulating cells before the effect on precursor cell maturation in the bone marrow becomes evident. Leukopenia is characterized by an abnormally low white blood cell count. The correct answer is D because the white cell count is not immediately affected by chemotherapy. Choices A, B, and C are incorrect as they pertain to red blood cells (hemoglobin and hematocrit), which are not directly related to the delayed onset of leukopenia.

4. Metformin (Glucophage) is administered to clients with type II diabetes mellitus. Metformin is an example of:

• A. an antihyperglycemic agent.
• B. a hypoglycemic agent.
• C. an insulin analogue.
• D. a pancreatic alpha cell stimulant

Correct answer: A

Rationale: Metformin is classified as an antihyperglycemic agent because it works by reducing hepatic glucose output and decreasing glucose absorption from the gut, thereby preventing hyperglycemia. Choice B, a hypoglycemic agent, is incorrect as hypoglycemic agents stimulate insulin production, which is not the mechanism of action of metformin. Choice C, an insulin analogue, is incorrect as metformin is not a type of insulin but a distinct medication. Choice D, a pancreatic alpha cell stimulant, is incorrect as metformin does not stimulate any pancreatic cells, but rather acts on the liver and gut to lower blood sugar levels.

5. A 55-year-old female asks a nurse the following, “Which mineral/vitamin is the most important to prevent the progression of osteoporosis?” The nurse should state:

• A. Potassium
• B. Magnesium
• C. Calcium
• D. Vitamin B12

Correct answer: C

Rationale: The correct answer is C: Calcium. Calcium is essential for maintaining bone health and is crucial in preventing osteoporosis. Adequate calcium intake, along with vitamin D, is vital for bone strength. While other minerals and vitamins are also important for overall health, in the context of preventing osteoporosis, calcium plays a primary role. Potassium (Choice A), Magnesium (Choice B), and Vitamin B12 (Choice D) are important for various bodily functions but are not as directly linked to preventing osteoporosis as calcium.
