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. The health care provider's progress note for a patient states that the complete blood count (CBC) shows a 'shift to the left.' Which assessment finding will the nurse expect?

• A. Cool extremities
• B. Pallor and weakness
• C. Elevated temperature
• D. Low oxygen saturation

Correct answer: C

Rationale: The correct answer is C: Elevated temperature. When a CBC shows a 'shift to the left,' it indicates elevated levels of immature polymorphonuclear neutrophils (bands), which is a sign of infection. In response to the infection, the body increases its temperature as part of the immune response. Choices A, B, and D are incorrect because cool extremities, pallor and weakness, and low oxygen saturation are not typically associated with a 'shift to the left' in a CBC; they are more indicative of other conditions or issues.

4. A 52-year-old patient has a new diagnosis of pernicious anemia. The nurse determines that the patient understands the teaching about the disorder when the patient states:

• A. I need to start eating more red meat and liver.
• B. I will stop having a glass of wine with dinner.
• C. I could choose nasal spray rather than injections of vitamin B12.
• D. I will need to take a proton pump inhibitor such as omeprazole (Prilosec).

Correct answer: C

Rationale: The correct answer is C. Pernicious anemia is a condition where the body can't absorb enough vitamin B12. Treatment usually involves lifelong replacement of vitamin B12. In this case, the patient understanding the disorder is correctly demonstrated by choosing nasal spray or injections of vitamin B12 for replacement therapy. Choices A, B, and D are incorrect because increasing red meat/liver intake, stopping wine consumption, or taking a proton pump inhibitor like omeprazole do not address the primary issue of vitamin B12 absorption in pernicious anemia.

5. Several patients call the outpatient clinic and ask to make an appointment as soon as possible. Which patient should the nurse schedule to be seen first?

• A. A 44-year-old with sickle cell anemia who reports his eyes always look somewhat yellow
• B. A 23-year-old with no previous health problems who has a nontender lump in the axilla
• C. A 50-year-old with early-stage chronic lymphocytic leukemia who reports chronic fatigue
• D. A 19-year-old with hemophilia who wants to learn to self-administer factor VII replacement

Correct answer: B

Rationale: The patient's young age and the presence of a nontender lump in the axilla raise concerns for possible lymphoma, which requires prompt evaluation and treatment. This patient should be seen first to rule out any serious underlying condition. Choice A is less urgent as yellowish eyes in sickle cell anemia may be due to jaundice but not necessarily an acute issue. Choice C, a 50-year-old with chronic fatigue related to early-stage chronic lymphocytic leukemia, is a known condition that can be managed on a routine basis. Choice D, a 19-year-old with hemophilia wanting to self-administer factor VII replacement, is important but less urgent compared to the potential lymphoma presentation in choice B.
