The physician orders a platelet count to be performed on Mrs. Smith after breakfast. The nurse is responsible for:
- A. Instructing the patient about this diagnostic test
- B. Writing the order for this test
- C. Giving the patient breakfast
- D. All of the above
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.
The physician orders a maintenance dose of 5,000 units of subcutaneous heparin (an anticoagulant) daily. Nursing responsibilities for Mrs. Mitchell now include:
- A. Reviewing daily activated partial thromboplastin time (APTT) and prothrombin time.
- B. Reporting an APTT above 45 seconds to the physician
- C. Assessing the patient for signs and symptoms of frank and occult bleeding
- D. All of the above
Correct Answer: D
Rationale: The correct answer is D. When a physician orders a maintenance dose of subcutaneous heparin, nursing responsibilities include reviewing daily activated partial thromboplastin time (APTT) and prothrombin time to monitor the patient's coagulation status, reporting an APTT above 45 seconds to the physician as it may indicate a risk of bleeding, and assessing the patient for signs and symptoms of frank and occult bleeding, which are potential adverse effects of anticoagulant therapy. Therefore, all the options listed are essential nursing responsibilities when a patient is on subcutaneous heparin therapy.

- B. Before the procedure, the patient should remove all jewelry, metallic objects, and buttons above the waist
- C. A signed consent is not required
- D. Eating, drinking, and medications are allowed before this test
Correct Answer: A
Rationale: The correct answer is A because there are contraindications for chest X-rays, such as pregnancy or concerns about radiation exposure. Patients may need to remove jewelry and metallic objects to prevent interference with the imaging. While a signed consent is typically not required for a routine chest X-ray, there are specific situations where consent may be necessary. It is essential for patients to follow fasting instructions before certain types of chest X-rays to obtain accurate results.
