1. Septic, anaphylactic, and neurogenic shock are all categorized as:
- A. Hypovolemic shock
- B. Cardiogenic shock
- C. Distributive shock
- D. Obstructive shock
Correct answer: C
Rationale: Septic, anaphylactic, and neurogenic shock are all types of distributive shock. Distributive shock is characterized by a decrease in systemic vascular resistance, leading to poor tissue perfusion. Septic shock is caused by severe infection, anaphylactic shock is an extreme allergic reaction, and neurogenic shock results from damage to the nervous system. Hypovolemic shock (Choice A) is characterized by a decrease in intravascular volume, cardiogenic shock (Choice B) is due to heart failure, and obstructive shock (Choice D) results from obstruction of blood flow. Therefore, the correct categorization for septic, anaphylactic, and neurogenic shock is distributive shock.
2. The nurse caring for Mrs. J is prepared to suction her endotracheal tube. Which of the following interventions will reduce hypoxia during this procedure?
- A. Hyperoxygenate Mrs. J for up to 60 seconds prior to starting
- B. Administer 15 mL of sterile fluid into the tube prior to suctioning
- C. Suction for no longer than 30 seconds at a time
- D. Wait 30 seconds after suctioning before attempting again
Correct answer: A
Rationale: Before suctioning a client's endotracheal tube, it is essential to hyperoxygenate the client for approximately 30 to 60 seconds. Hyperoxygenation helps increase oxygen delivery to the tissues, reducing the risk of hypoxia during and after the suctioning procedure. Administering fluid into the tube before suctioning (Choice B) is unnecessary and can lead to complications. Suctioning for no longer than 30 seconds at a time (Choice C) is a general guideline but does not specifically address reducing hypoxia. Waiting 30 seconds after suctioning before attempting again (Choice D) may lead to inadequate oxygenation and potential hypoxia, making it less effective in preventing this complication compared to hyperoxygenation prior to suctioning.
3. Which of these clients is likely to receive sublingual morphine?
- A. A 75-year-old woman in a hospice program
- B. A 40-year-old man who just had throat surgery
- C. A 20-year-old woman with trigeminal neuralgia
- D. A 60-year-old man who has a painful incision
Correct answer: A
Rationale: The correct answer is a 75-year-old woman in a hospice program. Sublingual morphine is commonly used in hospice care because patients may have difficulty swallowing, and intravenous access can be uncomfortable and not ideal for palliative care. Choice B, a 40-year-old man who just had throat surgery, is less likely to receive sublingual morphine as he may be able to swallow, and other pain management options may be more suitable. Choice C, a 20-year-old woman with trigeminal neuralgia, would typically require specific medications targeting neuropathic pain rather than sublingual morphine. Choice D, a 60-year-old man with a painful incision, may benefit from localized pain relief or other systemic pain management options, but sublingual morphine is not usually the first choice for this type of pain.
4. A client complained of nausea, a metallic taste in her mouth, and fine hand tremors 2 hours after her first dose of lithium carbonate (Lithane). What is the nurse's best explanation of these findings?
- A. These side effects are common and should subside in a few days.
- B. The client is probably having an allergic reaction and should discontinue the drug.
- C. Taking the lithium on an empty stomach should decrease these symptoms.
- D. Decreasing dietary intake of sodium and fluids should minimize the side effects.
Correct answer: A
Rationale: The correct answer is, 'These side effects are common and should subside in a few days.' Nausea, metallic taste, and fine hand tremors are common side effects of lithium carbonate (Lithane) and typically diminish within a few days as the body adjusts to the medication. Option B is incorrect because these symptoms are not indicative of an allergic reaction. Option C is incorrect as taking lithium on an empty stomach does not directly address or decrease these specific side effects. Option D is also incorrect as reducing sodium and fluid intake is not the recommended approach to managing these particular side effects of lithium.
5. The laboratory has just called with the arterial blood gas (ABG) results on four patients. Which result is most important for the nurse to report immediately to the health care provider?
- A. pH 7.34, PaO2 82 mm Hg, PaCO2 40 mm Hg, and O2 sat 97%
- B. pH 7.35, PaO2 85 mm Hg, PaCO2 45 mm Hg, and O2 sat 95%
- C. pH 7.46, PaO2 90 mm Hg, PaCO2 32 mm Hg, and O2 sat 98%
- D. pH 7.31, PaO2 91 mm Hg, PaCO2 50 mm Hg, and O2 sat 96%
Correct answer: D
Rationale: The correct answer is D: pH 7.31, PaO2 91 mm Hg, PaCO2 50 mm Hg, and O2 sat 96%. These ABG results indicate uncompensated respiratory acidosis, a critical condition that requires immediate attention. In respiratory acidosis, there is an excess of carbon dioxide in the blood, leading to a decrease in pH. The other options present normal or near-normal ABG values, indicating adequate oxygenation and ventilation. Therefore, these values would not be as urgent to report compared to the patient with respiratory acidosis in option D.
