Correct Answer: A

Rationale: The nurse's responsibility in this scenario is to instruct the patient about the diagnostic test ordered by the physician. This includes explaining the purpose of the test, any necessary preparations, and what to expect. The nurse is not responsible for writing the order, as this is the physician's role. Additionally, providing breakfast is not directly related to the platelet count test. Therefore, the correct answer is A, which aligns with the nurse's role in educating and supporting the patient regarding the test.

Correct Answer: B

Rationale: The correct answer is B: Mashed potatoes and broiled chicken. Both mashed potatoes and broiled chicken are typically low in sodium content, making them suitable choices for a 500-mg low sodium diet. The other options, such as a ham and Swiss cheese sandwich on whole wheat bread, a tossed salad with oil and vinegar and olives, and chicken bouillon, may contain higher amounts of sodium and are not typically recommended for a low sodium diet.

Correct Answer: C

Rationale: The absence of the pedal pulse may not be significant if the patient has poor peripheral circulation or if the healthcare provider is focused on other pulse points. The pedal pulse is often weaker and may not always be palpable due to various factors, making its absence less concerning in certain situations. However, the absence of other pulses like radial or femoral pulses may indicate more critical conditions and require immediate attention.

Correct Answer: D
