1. Chemotherapeutic agents often produce a degree of myelosuppression including leukopenia. Leukopenia does not present immediately but is delayed several days or weeks because:
- A. the client's hemoglobin and hematocrit are normal.
- B. red blood cells are affected first.
- C. folic acid levels are normal.
- D. the current white cell count is not affected by chemotherapy.
Correct answer: D
Rationale: Leukopenia does not present immediately after chemotherapy because time is required to clear circulating cells before the effect on precursor cell maturation in the bone marrow becomes evident. Leukopenia is characterized by an abnormally low white blood cell count. The correct answer is D because the white cell count is not immediately affected by chemotherapy. Choices A, B, and C are incorrect as they pertain to red blood cells (hemoglobin and hematocrit), which are not directly related to the delayed onset of leukopenia.
2. A patient has experienced a severe third-degree burn to the trunk in the last 36 hours. Which phase of burn management is the patient in?
- A. Shock phase
- B. Emergent phase
- C. Healing phase
- D. Wound proliferation phase
Correct answer: A
Rationale: The correct answer is A: Shock phase. The shock phase occurs within the first 24-48 hours of burn management. During this phase, the focus is on stabilization, fluid resuscitation, and monitoring for potential complications. Choice B, the Emergent phase, is incorrect as it refers to the initial phase of burn care immediately after the injury. Choice C, the Healing phase, occurs later in the treatment process when the wound starts to repair itself. Choice D, the Wound proliferation phase, is not a recognized phase in burn management.
3. After a left heart catheterization (LHC), a client complains of severe foot pain on the side of the femoral stick. The nurse notes pulselessness, pallor, and a cold extremity. What should the nurse's next action be?
- A. Administer an anticoagulant.
- B. Warm the room and re-assess.
- C. Increase IV fluids.
- D. Notify the physician stat.
Correct answer: D
Rationale: The correct action for the nurse to take next is to notify the physician immediately (stat). The client's symptoms of foot pain, pulselessness, pallor, and cold extremity suggest a potential vascular complication, such as arterial occlusion. Prompt notification of the physician is crucial as this condition requires urgent intervention to restore blood flow and prevent tissue damage. Administering an anticoagulant (Choice A) without physician evaluation could be harmful as the underlying cause needs to be determined first. Warming the room and re-assessing (Choice B) may delay necessary treatment. Increasing IV fluids (Choice C) is unlikely to address the urgent vascular issue indicated by the symptoms described.
4. The nurse is caring for a client who is 28 weeks pregnant and complains of swollen hands and feet. Which symptom below would cause the greatest concern?
- A. Nasal congestion
- B. Hiccups
- C. Blood glucose of 150
- D. Muscle spasms
Correct answer: D
Rationale: The correct answer is muscle spasms because they can be indicative of a severe condition like preeclampsia, which is a serious complication during pregnancy characterized by high blood pressure and signs of damage to another organ system, most often the liver and kidneys. Nasal congestion and hiccups are common discomforts during pregnancy and do not pose a severe risk to the client or fetus. A blood glucose level of 150, while slightly elevated, may not be alarming in a pregnant individual and can be managed through dietary modifications or medication adjustments. Muscle spasms, especially in the context of pregnancy, should be taken seriously and thoroughly assessed to rule out any underlying serious conditions.
5. Which of the following medications is a serotonin antagonist that might be used to relieve nausea and vomiting?
- A. metoclopramide (Reglan)
- B. ondansetron (Zofran)
- C. hydroxyzine (Vistaril)
- D. prochlorperazine (Compazine)
Correct answer: B
Rationale: Zofran is a serotonin antagonist that can be used to relieve nausea and vomiting. Ondansetron (Zofran) works by blocking serotonin receptors in the chemoreceptor trigger zone (CTZ) and the gastrointestinal tract. This action helps reduce nausea and vomiting. Metoclopramide (Reglan) works as a dopamine antagonist and also has prokinetic effects, making it effective for different conditions. Hydroxyzine (Vistaril) is an antihistamine with antiemetic properties, but it does not act as a serotonin antagonist. Prochlorperazine (Compazine) is a dopamine antagonist that is also used to treat nausea and vomiting, but not as a serotonin antagonist like ondansetron.
