Nursing Elites

1. A client who has a new prescription for warfarin (Coumadin) asks the nurse how the medication works. What explanation should the nurse provide?

• A. It dissolves blood clots
• B. It prevents the blood from clotting
• C. It thins the blood
• D. It decreases the risk of infection

Correct answer: B

Rationale: The correct answer is B: 'It prevents the blood from clotting.' Warfarin works by inhibiting the synthesis of vitamin K-dependent clotting factors in the liver, thereby preventing the formation of blood clots. Choice A is incorrect because warfarin does not dissolve existing blood clots but prevents new ones from forming. Choice C is partially correct but not as specific as choice B in explaining how warfarin works. Choice D is unrelated to the mechanism of action of warfarin and is incorrect.

2. The nurse is performing a physical assessment of a client with a history of smoking and notes a barrel chest. Which action is most important for the nurse to take next?

• A. Assess the client's oxygen saturation level
• B. Teach the client pursed-lip breathing techniques
• C. Determine the client's history of lung disease
• D. Obtain an arterial blood gas sample

Correct answer: A

Rationale: Corrected Rationale: Assessing the client's oxygen saturation level is crucial when a nurse identifies a barrel chest. A barrel chest is often associated with chronic obstructive pulmonary disease (COPD), which can lead to impaired gas exchange and decreased oxygen saturation. Monitoring the oxygen saturation level will provide immediate information on the client's respiratory status. Teaching pursed-lip breathing techniques, determining lung disease history, and obtaining arterial blood gas samples are important interventions but assessing oxygen saturation takes precedence in this scenario due to its direct impact on the client's respiratory function.

3. The client is being taught how to take alendronate (Fosamax) for osteoporosis treatment. Which statement indicates that the client needs further teaching?

• A. I should take this medication at bedtime
• B. I will need to take this medication for at least 3 years
• C. I should sit up for 30 minutes after taking the medication
• D. I should take this medication with a full glass of water

Correct answer: A

Rationale: The correct answer is A because taking Fosamax at bedtime is incorrect. It should be taken in the morning with a full glass of water to prevent esophageal irritation. Choice B is correct; alendronate is typically taken for several years to treat osteoporosis. Choice C is correct as remaining upright for 30 minutes after taking Fosamax helps prevent esophageal irritation. Choice D is also correct as taking alendronate with a full glass of water is necessary to ensure proper absorption.

4. In the newborn nursery, the nurse admits a baby from labor and delivery who is suspected of having a congenital heart disease. Which finding helps to confirm this diagnosis?

• A. Pink lips and tongue with cyanotic hands and feet
• B. Respiration rate of 40 and heart rate of 144
• C. Centralized cyanosis and tachycardia when crying
• D. Desquamation from areas of cracked, parchment-like skin

Correct answer: C

Rationale: Centralized cyanosis and tachycardia are classic signs of congenital heart disease. Choice A is incorrect because cyanosis in the hands and feet is not specific to congenital heart disease. Choice B is incorrect as the vital signs provided are not specific indicators of congenital heart disease. Choice D is unrelated to the typical signs of congenital heart disease.

5. A client receiving amlodipine (Norvasc), a calcium channel blocker, develops 1+ pitting edema around the ankles. It is most important for the nurse to obtain what additional client data?

• A. Bladder distention
• B. Serum albumin level
• C. Abdominal girth
• D. Breath sounds

Correct answer: D

Rationale: The correct answer is 'D. Breath sounds.' When a client receiving amlodipine develops edema, it is crucial to assess for potential heart failure, a side effect of the medication. Checking breath sounds helps in identifying any signs of pulmonary edema, a severe complication of heart failure. Choices A, B, and C are less relevant in this context. Bladder distention could be associated with urinary issues, serum albumin level with malnutrition or liver disease, and abdominal girth with gastrointestinal problems, none of which directly relate to the potential heart failure induced by amlodipine.
