Nursing Elites

1. A patient with 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 case, with a platelet count of 42,000/µL, the count is not critically low, and the patient is not actively bleeding. Therefore, the nurse should consult with the healthcare provider before giving the transfusion. Choices B, C, and D are incorrect because the presence of petechiae, low blood pressure, and oozing from the venipuncture site are common findings in patients with ITP and do not necessarily require immediate consultation before administering a platelet transfusion.

2. The nurse is caring for a patient in the cardiac unit recovering from a cardiac bypass graft procedure. The patient's spouse comes out to the hallway and expresses concern about the patient's confusion since surgery was 3 days ago. An appropriate response by the nurse would be:

• A. Let me call the doctor right away.
• B. What specific concerns do you have?
• C. It is common for confusion to occur after this procedure.
• D. I'll have the counselor come meet you in the room.

Correct answer: C

Rationale: Choice C is the correct answer because confusion can be a common occurrence after cardiac surgeries due to factors such as anesthesia, medication, and the stress of the procedure. By acknowledging the spouse's concern and explaining that confusion is a known potential outcome, the nurse provides reassurance and education. Choices A, B, and D are incorrect because they do not directly address the spouse's concern about the patient's confusion or provide appropriate information about the situation.

3. The nurse is caring for a patient post coronary artery bypass graft who rates his/her pain as an 8 out of 10 on the subjective pain scale. Should the nurse choose to administer morphine sulfate intravenously as it has benefits to cardiac patients (select one that does not apply)?

• A. Decreasing myocardial oxygen supply
• B. Decreasing myocardial oxygen consumption
• C. Decreasing heart rate
• D. Increasing blood pressure

Correct answer: D

Rationale: Morphine sulfate, a potent opioid analgesic, can cause vasodilation leading to a decrease in blood pressure rather than an increase. Choice A is incorrect as morphine can decrease myocardial oxygen consumption by reducing the workload of the heart. Choice B is incorrect as morphine can decrease heart rate as a side effect. Choice C is incorrect as morphine typically decreases blood pressure rather than increasing it.

4. 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.

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.
