Nursing Elites

1. A client with cirrhosis is at risk for bleeding due to impaired liver function. Which laboratory result is the most important to monitor?

• A. Blood urea nitrogen (BUN)
• B. Prothrombin time (PT)
• C. Aspartate aminotransferase (AST)
• D. Serum albumin

Correct answer: B

Rationale: Prothrombin time (PT) measures the time it takes for blood to clot and is a critical indicator of bleeding risk in clients with liver dysfunction. Impaired liver function reduces clotting factor production, leading to an increased PT, which requires close monitoring. Monitoring BUN (Choice A) is more indicative of kidney function, not clotting ability. Aspartate aminotransferase (AST) (Choice C) and serum albumin (Choice D) are important indicators of liver function, but they do not directly assess the client's bleeding risk.

2. An adult client is admitted to the emergency department after falling from a ladder. While waiting to have a CT scan, the client requests something for a severe headache. When the nurse offers a prescribed dose of acetaminophen, the client asks for something stronger. Which intervention should the nurse implement?

• A. Administer an anti-inflammatory medication instead
• B. Explain the reason for using only non-narcotics
• C. Consult the healthcare provider about a stronger medication
• D. Administer a stronger medication as requested

Correct answer: B

Rationale: In this scenario, the nurse should explain the reason for using only non-narcotics. Following head trauma, non-narcotic medications such as acetaminophen are preferred to avoid masking symptoms of neurological changes, such as increased intracranial pressure, that could worsen after stronger pain medication. Administering an anti-inflammatory medication (Choice A) may not be appropriate as it may not address the severity of the headache. Consulting the healthcare provider about a stronger medication (Choice C) is important, but the immediate need is to educate the client on the rationale for using non-narcotic medications first. Administering a stronger medication as requested (Choice D) could potentially mask important symptoms and should be avoided in this situation.

3. What pathophysiological events occur sequentially in the development of atherosclerosis?

• A. Foam cells release growth factors.
• B. Smooth muscle grows over fatty streaks creating fibrous plaques.
• C. Macrophages consume low-density lipoprotein (LDL) and create foam cells.
• D. Arterial endothelium injury causes inflammation.

Correct answer: D

Rationale: The correct sequence of pathophysiological events in the development of atherosclerosis starts with arterial endothelium injury causing inflammation. This inflammation triggers the formation of foam cells by macrophages consuming low-density lipoprotein (LDL). Subsequently, smooth muscle grows over fatty streaks, creating fibrous plaques. Therefore, option D is the correct answer. Choices A, B, and C are incorrect because they do not reflect the accurate chronological order of events in the pathogenesis of atherosclerosis.

4. A client with hypothyroidism is prescribed levothyroxine. What symptom indicates that the dosage may need adjustment?

• A. Increased appetite and weight gain.
• B. Increased sensitivity to cold and dry skin.
• C. Increased heart palpitations and sweating.
• D. Increased shortness of breath and rapid heart rate.

Correct answer: B

Rationale: Increased sensitivity to cold and dry skin may indicate that the dosage of levothyroxine is too low, requiring adjustment. This symptom is typical of hypothyroidism when the body's metabolism slows down, leading to feeling cold and having dry skin. Choices A, C, and D present symptoms more commonly associated with hyperthyroidism, where the body is in a state of overactivity, leading to weight loss, increased heart rate, and sweating. Therefore, these symptoms would not indicate the need for dosage adjustment in a client with hypothyroidism.

5. A client with deep vein thrombosis (DVT) is prescribed heparin. What lab value should the nurse monitor to assess the effectiveness of the therapy?

• A. Prothrombin time (PT).
• B. Partial thromboplastin time (PTT).
• C. International Normalized Ratio (INR).
• D. Hemoglobin and hematocrit.

Correct answer: B

Rationale: The correct answer is B: Partial thromboplastin time (PTT). PTT is the lab value used to monitor the effectiveness of heparin therapy in clients with DVT. It measures the intrinsic pathway of coagulation and is prolonged by heparin therapy. Prothrombin time (PT) and International Normalized Ratio (INR) are primarily used to monitor warfarin therapy, not heparin. Checking hemoglobin and hematocrit levels is important but does not directly assess the effectiveness of heparin therapy in DVT.
