Nursing Elites

1. A patient who has immune thrombocytopenic purpura (ITP) has an order for a platelet transfusion. Which information indicates that the nurse should consult with the healthcare provider before obtaining and administering platelets?

• A. Platelet count is 42,000/µL
• B. Petechiae are present on the chest
• C. Blood pressure (BP) is 94/56 mm Hg
• D. Blood is oozing from the venipuncture site

Correct answer: A

Rationale: The correct answer is A. Platelet transfusions are not usually indicated until the platelet count is below 10,000 to 20,000/µL unless the patient is actively bleeding. In this scenario, the platelet count of 42,000/µL is not significantly low to warrant a platelet transfusion without active bleeding. Consulting with the healthcare provider is essential before giving the transfusion to ensure the appropriateness of the treatment. Choices B, C, and D are not directly related to the need for consulting before a platelet transfusion. Petechiae, low blood pressure, and oozing from the venipuncture site are common findings in patients with ITP and may not necessarily contraindicate a platelet transfusion at this platelet count.

2. 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.

3. A patient's complete blood count (CBC) shows a hemoglobin of 19 g/dL and a hematocrit of 54%. Which question should the nurse ask to determine possible causes of this finding?

• A. Have you had any recent weight loss?
• B. Do you have any history of lung disease?
• C. Have you noticed any dark or bloody stools?
• D. What is your dietary intake of meats and proteins?

Correct answer: B

Rationale: The correct answer is B: "Do you have any history of lung disease?" The elevated hemoglobin and hematocrit levels suggest polycythemia, which can be seen in conditions like chronic obstructive pulmonary disease (COPD). Option A is less relevant as weight loss is not typically associated with these blood count findings. Option C is more indicative of gastrointestinal bleeding rather than a respiratory issue. Option D focuses on dietary factors, which are less likely to cause such significant elevations in hemoglobin and hematocrit levels as seen in this case.

4. A 62-year-old man with chronic anemia is experiencing increased fatigue and occasional palpitations at rest. The nurse would expect the patient's laboratory test findings to include

• A. an RBC count of 4,500,000/μL.
• B. a hematocrit (Hct) value of 38%.
• C. normal red blood cell (RBC) indices.
• D. a hemoglobin (Hgb) of 8.6 g/dL.

Correct answer: B

Rationale: The correct answer is B. In chronic anemia, the hematocrit (Hct) value is a crucial indicator of the proportion of red blood cells in the blood. A hematocrit value of 38% indicates a lower than normal level of red blood cells, which aligns with the patient's symptoms of fatigue and palpitations. Choices A, C, and D are incorrect because a low RBC count, normal RBC indices, and a hemoglobin level of 8.6 g/dL do not specifically address the decreased red blood cell mass associated with chronic anemia.

5. 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.
