Nursing Elites

1. The healthcare provider is caring for a patient who is taking warfarin (Coumadin). Which laboratory value should the healthcare provider monitor closely?

• A. Platelet count.
• B. Prothrombin time (PT).
• C. Hemoglobin level.
• D. White blood cell count.

Correct answer: B

Rationale: Corrected Rationale: When caring for a patient on warfarin, monitoring prothrombin time (PT) is crucial. PT helps assess the blood's ability to clot properly, ensuring the patient maintains therapeutic anticoagulation levels while minimizing bleeding risks. Platelet count (Choice A) is important but not the most critical for warfarin therapy. Hemoglobin level (Choice C) and white blood cell count (Choice D) are not directly related to monitoring the effects of warfarin.

2. For a patient with asthma, what is the primary purpose of prescribing salmeterol?

• A. Relieve acute bronchospasm
• B. Prevent asthma attacks
• C. Suppress cough
• D. Thin respiratory secretions

Correct answer: B

Rationale: Salmeterol is classified as a long-acting beta2-agonist, which is used to prevent asthma attacks by providing extended bronchodilation. It is not typically used for immediate relief of acute bronchospasm or for suppressing cough. Additionally, salmeterol does not have the primary purpose of thinning respiratory secretions.

3. The client has just been diagnosed with Addison's disease. Which clinical manifestation should the nurse expect to find?

• A. Hypertension and hyperglycemia.
• B. Hyperpigmentation and hypotension.
• C. Exophthalmos and tachycardia.
• D. Weight gain and fluid retention.

Correct answer: B

Rationale: Hyperpigmentation and hypotension are classic clinical manifestations of Addison's disease due to decreased cortisol production. Hyperpigmentation occurs due to elevated levels of ACTH, leading to increased melanin synthesis. Hypotension results from aldosterone deficiency, causing sodium loss and volume depletion.

4. What is the primary cause of jaundice in a client with liver cirrhosis?

• A. Decreased bile production
• B. Increased bilirubin levels
• C. Hepatic inflammation
• D. Portal hypertension

Correct answer: B

Rationale: Jaundice in a client with liver cirrhosis is primarily caused by increased bilirubin levels. In liver cirrhosis, impaired liver function leads to the accumulation of bilirubin in the blood, resulting in jaundice. Bilirubin is a yellow pigment produced from the breakdown of red blood cells, and its elevation is a common manifestation of liver dysfunction. Choices A, C, and D are incorrect. While decreased bile production can contribute to jaundice, in liver cirrhosis, the key factor is the buildup of bilirubin due to liver dysfunction, not a decrease in bile production. Hepatic inflammation and portal hypertension are associated with liver cirrhosis but are not the primary causes of jaundice in this context.

5. A client with liver failure is at an increased risk of bleeding due to the inability to synthesize prothrombin in the liver. What factor most likely contributes to this loss of function?

• A. Alterations in glucose metabolism
• B. Retention of bile salts
• C. Inadequate production of albumin by hepatocytes
• D. Inability of the liver to use vitamin K

Correct answer: D

Rationale: The correct answer is D. The liver's inability to use vitamin K is the most likely factor contributing to the loss of prothrombin synthesis in liver failure. Vitamin K is essential for the synthesis of prothrombin, a crucial clotting factor. In liver failure, impaired utilization of vitamin K leads to decreased production of prothrombin, increasing the risk of bleeding in affected individuals.
