1. Which class of drugs is the only source of a cure for septic shock?
- A. Antihypertensives
- B. Anti-infectives
- C. Antihistamines
- D. Anticholesteremics
Correct answer: B
Rationale: The correct answer is B: Anti-infectives. Anti-infective agents, such as antibiotics, are essential in treating septic shock as they can eliminate bacteria and halt the progression of the condition by stopping the production of endotoxins. Antihypertensives (Choice A) are used to lower blood pressure, antihistamines (Choice C) are used to treat allergic reactions, and anticholesteremics (Choice D) are used to lower cholesterol levels. However, none of these drug classes directly address the bacterial infection that underlies septic shock.
2. A client with a history of atrial fibrillation is prescribed warfarin (Coumadin). Which laboratory value is most concerning?
- A. INR of 3.0
- B. Prothrombin time (PT) of 15 seconds
- C. Hemoglobin of 10 g/dl
- D. White blood cell count
Correct answer: A
Rationale: An INR of 3.0 is most concerning in a client prescribed warfarin (Coumadin) as it indicates a high risk of bleeding, requiring immediate intervention. A high INR value suggests that the blood is taking longer to clot, putting the patient at an increased risk of hemorrhage. Prothrombin time (PT) measures how long it takes for blood to clot, but the specific value of 15 seconds is within the normal range. Hemoglobin of 10 g/dl indicates mild anemia and does not directly relate to the risk of bleeding associated with warfarin therapy. White blood cell count assesses immune function and infection risk, but it is not directly related to the anticoagulant effects of warfarin.
3. The nurse observes an adolescent client preparing to administer a prescribed corticosteroid medication using a metered dose inhaler. What action should the nurse take?
- A. Remind the client to hold their breath after inhaling the medication
- B. Confirm that the client has correctly shaken the inhaler
- C. Affirm that the client has correctly positioned the inhaler
- D. Ask the client if they have a spacer to use for this medication
Correct answer: A
Rationale: Corrected Rationale: Reminding the client to hold their breath after inhaling the medication is crucial as it helps ensure the medication is absorbed into the lungs. Option B is incorrect because shaking the inhaler is not directly related to the client's inhalation technique. Option C is incorrect as correct positioning of the inhaler is important but not the immediate action needed in this situation. Option D is incorrect as asking about the spacer is not the most relevant action to take at this moment.
4. Following a gunshot wound to the abdomen, a young adult male had an emergency bowel resection and received multiple blood products while in the operating room. His current blood pressure is 78/52 mm Hg, he is being mechanically ventilated, and his oxygen saturation is 87%. His laboratory values include hemoglobin 7.0 g/dL, platelets 20,000/mm³, and white blood cells 1,500/mm³. Based on these assessment findings, which intervention should the nurse implement first?
- A. Transfuse packed red blood cells.
- B. Obtain blood and sputum cultures.
- C. Infuse 1000 ml of normal saline.
- D. Titrate oxygen to keep O2 saturation at 90%.
Correct answer: A
Rationale: The client is exhibiting signs of severe anemia and hypovolemic shock, indicated by low hemoglobin levels and hypotension. The first priority is to address the low hemoglobin by transfusing packed red blood cells to improve oxygen-carrying capacity and perfusion to vital organs. While obtaining blood and sputum cultures is important for identifying potential infections, infusing normal saline can help with volume expansion but does not address the primary issue of severe anemia. Titrating oxygen to maintain an oxygen saturation of 90% is crucial but should follow the administration of packed red blood cells to optimize oxygen delivery.
5. A client with a history of chronic obstructive pulmonary disease (COPD) is admitted with pneumonia. Which laboratory value requires immediate intervention?
- A. Arterial blood gas (ABG) values
- B. Serum potassium level
- C. Serum sodium level
- D. Blood glucose level
Correct answer: A
Rationale: The correct answer is A: Arterial blood gas (ABG) values. In a client with COPD and pneumonia, ABG values are crucial as they provide essential information about the client's respiratory status, including oxygenation and acid-base balance. Immediate intervention may be required to optimize respiratory function based on ABG results. Serum potassium, sodium, and blood glucose levels are important parameters to monitor in various conditions but are not as directly related to the respiratory status in a client with COPD and pneumonia. Therefore, they do not require immediate intervention compared to ABG values.
