Nursing Elites

1. Which of the following is a sign of digoxin toxicity?

• A. Bradycardia
• B. Hypertension
• C. Tachycardia
• D. Tachypnea

Correct answer: A

Rationale: The correct answer is A, Bradycardia. Bradycardia, or a slower than normal heart rate, is a classic sign of digoxin toxicity. Digoxin is a medication commonly used to treat heart conditions, but an excess of digoxin in the body can lead to toxicity. This toxicity can manifest as various symptoms, with bradycardia being one of the most common ones. Hypertension (high blood pressure) and tachycardia (fast heart rate) are not typical signs of digoxin toxicity. Tachypnea, which refers to rapid breathing, is also not a common sign of digoxin toxicity.

2. A nurse is teaching a newly licensed nurse about using a portable oxygen system. What instruction should the nurse include?

• A. The oxygen should be kept in a storage room when not in use.
• B. Turn off the oxygen when not in use.
• C. Check the oxygen level regularly using a pulse oximeter.
• D. Never leave the oxygen running when transporting a client.

Correct answer: C

Rationale: The correct answer is to check the oxygen level regularly using a pulse oximeter. This instruction is crucial as it ensures safe and adequate oxygenation for the client. Option A is incorrect as oxygen should not be stored in a storage room but in a well-ventilated area. Option B is not ideal as oxygen should be left on unless otherwise specified by a healthcare provider. Option D is also important but not directly related to the primary instruction of monitoring oxygen levels.

3. A client who has a prescription for insulin glargine is talking to a nurse. Which of the following statements by the client indicates an understanding of the teaching?

• A. I will mix this insulin with my regular insulin before injecting it.
• B. I will store this insulin in the refrigerator after opening it.
• C. I will take this insulin twice a day.
• D. I will inject this insulin when my blood glucose is above 200 mg/dL.

Correct answer: B

Rationale: The correct answer is B because insulin glargine should be stored in the refrigerator after opening to maintain its potency. Choice A is incorrect as insulin glargine should not be mixed with other insulins. Choice C is incorrect because insulin glargine is typically taken once a day. Choice D is incorrect because insulin glargine is usually taken regardless of blood glucose levels.

4. A healthcare provider is reviewing laboratory results for a client who is receiving heparin therapy. Which of the following results indicates that the medication is effective?

• A. Platelets 250,000/mm³
• B. aPTT 60 seconds
• C. Hemoglobin 15 g/dL
• D. INR 1.5

Correct answer: B

Rationale: An aPTT of 60 seconds indicates that the client is receiving an effective dose of heparin. The activated partial thromboplastin time (aPTT) measures the time it takes for blood to clot and is used to monitor heparin therapy. A therapeutic range for aPTT during heparin therapy is usually 1.5 to 2 times the control value, which is around 25-35 seconds. Platelets, hemoglobin, and INR values are not direct indicators of the effectiveness of heparin therapy.

5. A nurse is caring for a client who has cirrhosis. Which of the following laboratory findings should the nurse expect?

• A. Increased bilirubin levels
• B. Decreased albumin levels
• C. Increased prothrombin time
• D. Decreased serum glucose levels

Correct answer: A

Rationale: Corrected Rationale: Increased bilirubin levels are expected in clients with cirrhosis due to impaired liver function. Elevated bilirubin levels are commonly seen in cirrhosis as the liver's ability to process bilirubin is compromised. Decreased albumin levels and increased prothrombin time are also associated with cirrhosis, but the most specific finding related to liver dysfunction among the choices provided is increased bilirubin levels. Decreased serum glucose levels are not typically associated with cirrhosis.
