Nursing Elites

1. The nurse is caring for a patient post-coronary artery bypass graft procedure who is on a nitroglycerin intravenous drip. The nurse understands the importance of nitroglycerin with this procedure as:

• A. Decreasing myocardial oxygen supply.
• B. Increasing preload.
• C. Decreasing cardiac output.
• D. Decreasing afterload.

Correct answer: D

Rationale: Nitroglycerin is a vasodilator that works by decreasing afterload, which is the pressure the heart must work against to eject blood during systole. By reducing afterload, nitroglycerin helps the heart pump more effectively and decreases the workload on the heart. This results in improved cardiac output and decreased myocardial oxygen demand. Choices A, B, and C are incorrect because nitroglycerin does not decrease myocardial oxygen supply, increase preload, or decrease cardiac output.

2. A patient with pancytopenia of unknown origin is scheduled for the following diagnostic tests. The nurse will provide a consent form to sign for which test?

• A. Bone marrow biopsy
• B. Abdominal ultrasound
• C. Complete blood count (CBC)
• D. Activated partial thromboplastin time (aPTT)

Correct answer: A

Rationale: In the case of a patient with pancytopenia of unknown origin, a bone marrow biopsy is usually indicated to determine the cause. A bone marrow biopsy is a minor surgical procedure that requires the patient or guardian to sign a surgical consent form. Abdominal ultrasound (Choice B) is not typically used to diagnose pancytopenia. A Complete Blood Count (CBC) (Choice C) is a routine blood test and does not require a specific consent form. Activated Partial Thromboplastin Time (aPTT) (Choice D) is a coagulation test and not typically performed to diagnose pancytopenia.

3. A patient who has acute myelogenous leukemia develops an absolute neutrophil count of 850/µL while receiving outpatient chemotherapy. Which action by the outpatient clinic nurse is most appropriate?

• A. Discuss the need for hospital admission to treat the neutropenia
• B. Teach the patient to administer filgrastim (Neupogen) injections
• C. Plan to discontinue the chemotherapy until the neutropenia resolves
• D. Order a high-efficiency particulate air (HEPA) filter for the patient's home

Correct answer: B

Rationale: The correct answer is B because filgrastim (Neupogen) is a medication used to stimulate the production of neutrophils. Teaching the patient to self-administer these injections can help increase the neutrophil count and reduce the risk of infection. Option A is incorrect as hospital admission may not be necessary if the patient can manage the condition at home. Option C is not ideal as discontinuing chemotherapy can impact the leukemia treatment. Option D is unrelated to managing neutropenia in this scenario.

4. A patient is being discharged after an emergency splenectomy following a motor vehicle crash. Which instructions should the nurse include in the discharge teaching?

• A. Check frequently for swollen lymph nodes.
• B. Watch for excessive bleeding or bruising.
• C. Take iron supplements to prevent anemia.
• D. Wash hands and avoid individuals who are ill.

Correct answer: D

Rationale: The correct answer is D. After a splenectomy, the patient is at an increased risk of infection, particularly from gram-positive bacteria. Washing hands and avoiding contact with individuals who are ill are crucial to reduce this risk. Choice A is incorrect because checking for swollen lymph nodes is not a priority after a splenectomy. Choice B is incorrect as while bleeding is a concern, it is more immediate post-operatively. Choice C is incorrect as iron supplements do not specifically relate to the risk of infection post-splenectomy.

5. The nurse reviews the laboratory test results of a patient admitted with abdominal pain. Which information will be most important for the nurse to communicate to the health care provider?

• A. Monocytes 4%
• B. Hemoglobin 13.6 g/dL
• C. Platelet count 168,000/μL
• D. White blood cell (WBC) count 15,500/μL

Correct answer: A

Rationale: The correct answer is A. A low percentage of monocytes can indicate a viral infection. This is crucial information to communicate as it suggests a specific type of infection that may require targeted treatment. Choices B, C, and D do not directly relate to an infectious process and are within normal ranges, so they are not as urgent to communicate to the healthcare provider in this context.
