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. The healthcare provider should utilize data about which of the following to provide information about the nutritional status of a client being evaluated for malnutrition?

• A. triceps skinfold measurement
• B. fasting blood glucose level
• C. hemoglobin A1c level
• D. serum lipid profile results

Correct answer: A

Rationale: Objective anthropometric measurements such as triceps skinfold and mid-arm circumference (MAC), along with weight, are usually used to diagnose malnutrition. Triceps skinfold measurement specifically helps assess body fat and muscle mass, providing valuable information about the client's nutritional status. Fasting blood glucose level, hemoglobin A1c level, and serum lipid profile results are important tests in assessing different aspects of health such as diabetes management and cardiovascular risk, but they are not specific indicators of malnutrition.

3. 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.

4. Is head lag expected to be resolved by 4 months of age? Continuing head lag at 6 months of age may indicate?

• A. Dizziness and orthostatic hypotension.
• B. Nausea, vomiting, diarrhea, or constipation, and stomach cramps.
• C. Drowsiness, lethargy, and fatigue.
• D. Neuropathy and tingling in the extremities.

Correct answer: B

Rationale: Head lag is a developmental milestone that should be resolved by 4 months of age. Continuing head lag at 6 months of age may indicate potential developmental delays or muscle weakness. The correct answer, 'Nausea, vomiting, diarrhea, or constipation, and stomach cramps,' reflects symptoms that could be associated with developmental delays or underlying health conditions. Dizziness and orthostatic hypotension (Choice A) are unlikely to be directly related to head lag. Choices C and D present symptoms that are unrelated to the issue of continued head lag at 6 months of age.

5. Ten-year-old Jackie is admitted to the hospital with a medical diagnosis of Rheumatic Fever. She relates a history of 'a sore throat about a month ago.' Bed rest with bathroom privileges is prescribed. Which of the following nursing assessments should be given the highest priority when assessing Jackie's condition?

• A. her response to hospitalization
• B. the presence of a macular rash on her trunk
• C. her cardiac status
• D. the presence of polyarthritis and joint pain

Correct answer: C

Rationale: Monitoring Jackie's cardiac status is of the highest priority in a patient with rheumatic fever. Rheumatic fever can lead to permanent cardiac damage, making it crucial to closely monitor the heart. Assessing for signs of carditis, such as murmurs or other cardiac symptoms, is essential. The second priority is evaluating joint symptoms for the presence of polyarthritis and pain, which are common manifestations of rheumatic fever. While assessing Jackie's response to hospitalization is important for her emotional well-being, it is not the highest priority. The presence of a macular rash, although relevant, is not as high a priority as monitoring cardiac status or assessing joint symptoms.
