Nursing Elites

1. A client is experiencing shortness of breath and wheezing. What is the nurse's first action?

• A. Administer bronchodilator medication
• B. Check the client's oxygen saturation
• C. Encourage the client to use pursed-lip breathing
• D. Elevate the head of the bed

Correct answer: A

Rationale: Administering a bronchodilator is the priority intervention to open the airways and relieve wheezing and shortness of breath. Bronchodilators work quickly to dilate the airways, making it easier for the client to breathe. Checking oxygen saturation is important but can be done after initiating bronchodilator therapy. Encouraging pursed-lip breathing and elevating the head of the bed can help improve breathing patterns but should follow the administration of the bronchodilator.

2. What are the primary pathophysiological mechanisms responsible for ascites in liver failure?

• A. Decreased liver enzymes.
• B. Increased hydrostatic pressure in portal circulation.
• C. High bilirubin levels.
• D. Fluid shifts due to decreased serum proteins.

Correct answer: B

Rationale: The correct answer is B: Increased hydrostatic pressure in portal circulation. Ascites in liver failure is primarily caused by fluid shifts from the intravascular space to the interstitial space due to increased hydrostatic pressure in the portal circulation. Choice A is incorrect as ascites is not caused by decreased liver enzymes. Choice C is incorrect as high bilirubin levels are not the primary mechanism for ascites in liver failure. Choice D is incorrect as fluid shifts in ascites are due to decreased serum proteins, not increased serum proteins.

3. A client with type 2 diabetes mellitus arrives at the clinic reporting episodes of weakness and palpitations. Which finding should the nurse identify may indicate an emerging situation?

• A. History of hypertension
• B. Fingertips feel numb
• C. Reduced deep tendon reflexes
• D. Elevated fasting blood glucose level

Correct answer: B

Rationale: Numb fingertips may suggest neuropathy, a common complication of diabetes that may indicate a worsening condition. Episodes of weakness and palpitations, combined with neuropathy symptoms, could also suggest hypoglycemia or poor glycemic control, requiring further investigation. The other choices are less likely to be directly related to the client's current symptoms. While a history of hypertension is a common comorbidity in clients with diabetes, it may not directly explain the reported weakness and palpitations. Reduced deep tendon reflexes are more indicative of certain neurological conditions rather than acute emerging situations related to the client's current symptoms. An elevated fasting blood glucose level is expected in a client with type 2 diabetes and may not be the primary indicator of an emerging situation in this context.

4. An older client is admitted with fluid volume deficit and dehydration. Which assessment finding is the best indicator of hydration status?

• A. Urine specific gravity of 1.040.
• B. Systolic blood pressure decreases by 10 points when standing.
• C. The client denies feeling thirsty.
• D. Skin turgor exhibits tenting on the forearm.

Correct answer: A

Rationale: In the context of fluid volume deficit and dehydration, urine specific gravity of 1.040 is the best indicator of hydration status. High urine specific gravity indicates concentrated urine, suggesting dehydration. Choice B, systolic blood pressure decreasing when standing, is more indicative of orthostatic hypotension rather than hydration status. Choice C, denial of thirst, is a subjective finding and may not always reflect actual hydration status. Choice D, skin turgor exhibiting tenting on the forearm, is a sign of dehydration but may not be as accurate as urine specific gravity in assessing hydration status.

5. 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.
