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 working in an emergency center collects physical evidence 6 hours following a reported sexual assault. After placing the samples in sealed containers, which action is most important for the nurse to implement?

• A. Maintain possession of the evidence collection kit at all times until submitted to law enforcement
• B. Provide discharge instructions for prophylactic antibiotics, pregnancy, and HIV prevention medication
• C. Document the characteristics of the various sites of sample collection
• D. Assist the client with toileting, hygiene, and dressing with clean clothes

Correct answer: A

Rationale: Maintaining possession of the evidence collection kit at all times until submitted to law enforcement is crucial to ensure the integrity of the chain of custody. This step helps prevent tampering or contamination of the evidence, which is vital for the legal process. Providing discharge instructions for medications, documenting sample characteristics, and assisting the client with personal care are important aspects of care but not the immediate priority when handling forensic evidence in a sexual assault case.

3. A client with diabetes mellitus reports feeling shaky and has a blood glucose level of 60 mg/dl. What action should the nurse take?

• A. Administer 15 grams of carbohydrate
• B. Administer a glucagon injection
• C. Provide a snack with protein
• D. Encourage the client to rest

Correct answer: A

Rationale: In the scenario described, the client is experiencing hypoglycemia with a blood glucose level of 60 mg/dl. The appropriate action for the nurse to take is to administer 15 grams of carbohydrate. Carbohydrate intake helps to rapidly raise blood sugar levels in cases of hypoglycemia. Administering a glucagon injection (Choice B) is not the initial treatment for mild hypoglycemia; it is typically used for severe hypoglycemia when the client is unable to consume oral carbohydrates. Providing a snack with protein (Choice C) is not the first-line intervention for hypoglycemia; immediate carbohydrate intake is necessary to raise blood sugar levels quickly. Encouraging the client to rest (Choice D) may be appropriate after administering the carbohydrate, but the priority is to address the low blood glucose levels by administering carbohydrates first.

4. While assessing a client who is experiencing Cheyne-Stokes respirations, the nurse observes periods of apnea. What action should the nurse implement?

• A. Elevate the head of the client's bed
• B. Auscultate the client's breath sounds
• C. Measure the length of the apneic periods
• D. Suction the client's oropharynx

Correct answer: C

Rationale: When a nurse observes periods of apnea in a client experiencing Cheyne-Stokes respirations, measuring the length of the apneic periods is essential. This action helps in determining the severity of Cheyne-Stokes respirations by providing valuable information about the duration of interrupted breathing cycles. Elevating the head of the client's bed (Choice A) may be beneficial in some respiratory conditions but is not the priority in Cheyne-Stokes respirations. Auscultating the client's breath sounds (Choice B) is a general assessment and may not directly address the issue of apnea in Cheyne-Stokes respirations. Suctioning the client's oropharynx (Choice D) is not the initial intervention for managing Cheyne-Stokes respirations unless secretions are obstructing the airway.

5. A male client with diabetes mellitus takes Novolin 70/30 insulin before meals and azithromycin (Zithromax) PO daily, using medication he brought from home. When the nurse delivers his breakfast tray, the client tells the nurse that he took his insulin but forgot to take his daily dose of the Zithromax an hour before breakfast as instructed. What action should the nurse implement?

• A. Offer to obtain a new breakfast tray in an hour so the client can take the Zithromax
• B. Instruct the client to eat his breakfast and take the Zithromax two hours after eating
• C. Tell the client to skip that day's dose and resume taking the Zithromax the next day
• D. Provide a PRN dose of an antacid to take with the Zithromax right after breakfast

Correct answer: B

Rationale: To ensure the effectiveness of the antibiotic and manage blood glucose levels, the client should take the Zithromax two hours after eating. Option A is incorrect because obtaining a new breakfast tray is not necessary to administer the missed dose. Option C is incorrect as skipping a dose can lead to decreased effectiveness of the antibiotic. Option D is incorrect because providing an antacid is not indicated in this situation.
