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. A patient with severe mitral regurgitation and decreased cardiac output is being cared for by a nurse. The nurse assesses the patient for mental status changes. What is the rationale for this intervention?
- A. Decreased cardiac output can cause hypoxia to the brain
- B. Mental status changes may be a side effect of the patient's medication
- C. Mitral regurgitation is a complication associated with some neurological disorders
- D. The patient may be confused about his diagnosis
Correct answer: A
Rationale: When caring for a patient with severe mitral regurgitation and decreased cardiac output, assessing for mental status changes is crucial. Decreased cardiac output can lead to inadequate perfusion and oxygenation of vital organs, including the brain, resulting in hypoxia. This hypoxia can manifest as mental status changes such as confusion, restlessness, or lethargy. Therefore, monitoring mental status helps in identifying potential hypoxic states and guiding appropriate interventions. The other options are incorrect as they do not directly correlate decreased cardiac output with potential hypoxia-induced mental status changes.
3. Mr. L was working in his garage at home and had an accident with a power saw. He is brought into the emergency department by a neighbor with a traumatic hand amputation. What is the first action of the nurse?
- A. Place a tourniquet at the level of the elbow
- B. Apply direct pressure to the injury
- C. Administer a bolus of 0.9% Normal Saline
- D. Elevate the injured extremity on a pillow
Correct answer: B
Rationale: The correct first action for the nurse in this scenario is to apply direct pressure to the injury. When a client presents with traumatic hand amputation causing excessive bleeding, the immediate goal is to control the bleeding. Applying direct pressure with a sterile dressing helps to stem the flow of blood and stabilize the patient. Placing a tourniquet at the level of the elbow should be avoided initially as it may lead to further complications such as tissue damage. Administering a bolus of 0.9% Normal Saline is not the priority in this situation where hemorrhage control is crucial. Elevating the injured extremity on a pillow does not address the primary concern of controlling the bleeding and stabilizing the patient.
4. While receiving normal saline infusions to treat a GI bleed, the nurse notes that the patient's lower legs have become edematous and auscultates crackles in the lungs. What should the nurse do first?
- A. Stop the saline infusion immediately
- B. Notify the physician
- C. Elevate the patient's legs
- D. Continue the infusion, as these findings are normal
Correct answer: A
Rationale: The correct answer is to stop the saline infusion immediately. The patient is showing signs of fluid volume overload due to rapid fluid replacement, indicated by lower leg edema and lung crackles. Continuing the infusion could worsen the overload and potentially lead to complications. Notifying the physician is important but should come after stopping the infusion to address the immediate issue. Elevating the patient's legs may help with edema but is not the priority in this situation. Continuing the infusion when the patient is already showing signs of fluid overload is contraindicated and can be harmful.
5. Which action should the nurse take to evaluate treatment effectiveness for a patient who has hepatic encephalopathy?
- A. Ask the patient to extend both arms forward.
- B. Request that the patient walk with eyes closed.
- C. Ask the patient to perform the Valsalva maneuver.
- D. Observe the patient's breathing pattern.
Correct answer: B
Rationale: To evaluate treatment effectiveness for a patient with hepatic encephalopathy, requesting the patient to walk with eyes closed is crucial. This test assesses the patient's balance, gait, and coordination, which can be impaired in hepatic encephalopathy due to altered mental status and brain function. Walking with eyes closed challenges the patient's sensory input and proprioception, providing valuable information on improvement or deterioration in neurological function. Asking the patient to extend both arms forward is used to check for asterixis, a sign often seen in hepatic encephalopathy, but it is not specific for evaluating treatment effectiveness. Performing the Valsalva maneuver is unrelated to assessing hepatic encephalopathy and is more commonly used in cardiac evaluations. Observing the patient's breathing pattern may be important in other conditions but is not directly relevant to evaluating treatment effectiveness for hepatic encephalopathy.
