Nursing Elites

1. A patient with chronic heart failure is prescribed carvedilol. What is the primary purpose of this medication?

• A. Increase cardiac output
• B. Reduce fluid retention
• C. Decrease heart rate
• D. Lower blood pressure

Correct answer: C

Rationale: Carvedilol, a beta-blocker, is primarily prescribed in patients with chronic heart failure to decrease heart rate and reduce the workload on the heart. By lowering the heart rate, carvedilol helps the heart function more efficiently and improves symptoms in patients with heart failure.

2. A client with severe anemia is being treated with a blood transfusion. Which assessment finding indicates a transfusion reaction?

• A. Elevated blood pressure.
• B. Fever and chills.
• C. Increased urine output.
• D. Bradycardia.

Correct answer: B

Rationale: Fever and chills are classic signs of a transfusion reaction. These symptoms indicate that the body is having a response to the transfused blood, possibly due to incompatibility or an immune reaction. Elevated blood pressure (choice A) is not a typical sign of a transfusion reaction. Increased urine output (choice C) and bradycardia (choice D) are also not characteristic signs of a transfusion reaction. It is crucial to recognize symptoms of a transfusion reaction promptly to prevent further complications and ensure appropriate management.

3. Following a CVA, the nurse assesses that a client has developed dysphagia, hypoactive bowel sounds, and a firm, distended abdomen. Which prescription for the client should the nurse question?

• A. Continuous tube feeding at 65 ml/hr via gastrostomy.
• B. Total parenteral nutrition to be infused at 125 ml/hour.
• C. Nasogastric tube connected to low intermittent suction.
• D. Metoclopramide (Reglan) intermittent piggyback.

Correct answer: A

Rationale: In a client with dysphagia and gastrointestinal symptoms such as hypoactive bowel sounds and a firm, distended abdomen, continuous tube feeding might exacerbate the symptoms. This can lead to complications and should be questioned by the nurse.

4. A patient with glaucoma is prescribed timolol eye drops. What is the primary action of this medication?

• A. Reduce intraocular pressure
• B. Dilate the pupils
• C. Constrict the pupils
• D. Enhance tear production

Correct answer: A

Rationale: Timolol eye drops are prescribed to reduce intraocular pressure in patients with glaucoma. By decreasing the pressure within the eye, timolol helps prevent damage to the optic nerve, which is crucial in managing glaucoma and preserving vision. Dilating or constricting the pupils or enhancing tear production are not the primary actions of timolol eye drops.

5. In evaluating a 10-year-old child with meningitis suspected of having diabetes insipidus, which finding is indicative of diabetes insipidus?

• A. Decreased urine specific gravity.
• B. Elevated urine glucose.
• C. Decreased serum potassium.
• D. Increased serum sodium.

Correct answer: A

Rationale: Diabetes insipidus is characterized by the kidneys' inability to concentrate urine, leading to decreased urine specific gravity. This results in the excretion of large volumes of dilute urine, causing a decrease in urine specific gravity. Therefore, when evaluating a suspected case of diabetes insipidus, a finding of decreased urine specific gravity is indicative of this condition.
