Nursing Elites

1. Which response by the nurse best explains the purpose of ranitidine (Zantac) for a patient admitted with bleeding esophageal varices?

• A. The medication will reduce the risk of aspiration.
• B. The medication will inhibit the development of gastric ulcers.
• C. The medication will prevent irritation of the enlarged veins.
• D. The medication will decrease nausea and improve appetite.

Correct answer: C

Rationale: The correct answer is: 'The medication will prevent irritation of the enlarged veins.' Esophageal varices are dilated submucosal veins. The therapeutic action of H2-receptor blockers in patients with esophageal varices is to prevent irritation and bleeding from the varices caused by reflux of acidic gastric contents. While ranitidine can decrease the risk of peptic ulcers, reduce nausea, and help prevent aspiration pneumonia, the primary purpose of H2-receptor blockade in this patient is to prevent irritation and bleeding from the varices, not the other listed effects.

2. A client is scheduled for a percutaneous transluminal coronary angioplasty (PTCA). The nurse knows that a PTCA is:

• A. Surgical repair of a diseased coronary artery
• B. Placement of an automatic internal cardiac defibrillator
• C. Procedure that compresses plaque against the wall of the diseased coronary artery to improve blood flow
• D. Non-invasive radiographic examination of the heart

Correct answer: C

Rationale: Percutaneous transluminal coronary angioplasty (PTCA) is a procedure that compresses plaque against the wall of the diseased coronary artery to improve blood flow. It is performed during a cardiac catheterization to improve coronary artery blood flow in a diseased artery. Surgical repair of a diseased coronary artery is typically done through procedures like aorto-coronary bypass graft (ACBG) rather than PTCA. Placement of an automatic internal cardiac defibrillator (AICD) is a different procedure used for managing cardiac arrhythmias. Non-invasive radiographic examination of the heart refers to procedures like echocardiography or cardiac MRI, not PTCA.

3. The nurse is discussing negativism with the parents of a 30-month-old child. How should the nurse advise the parents to best respond to this behavior?

• A. Reprimand the child and give a 15-minute 'time out'
• B. Maintain a permissive attitude for this behavior
• C. Use patience and a sense of humor to deal with this behavior
• D. Assert authority over the child through limit setting

Correct answer: C

Rationale: Use patience and a sense of humor to deal with this behavior. The nurse should help the parents understand that negativism is a normal part of a toddler's growth towards autonomy. Reacting with patience and humor can help diffuse the situation and maintain a positive relationship with the child. Reprimanding the child and giving a 'time out' (Choice A) may not be effective for addressing negativism and can lead to power struggles. Maintaining a permissive attitude (Choice B) may reinforce negative behavior. Asserting authority through limit setting (Choice D) may be necessary in some situations, but using patience and humor is a more effective initial approach for handling negativism.

4. A healthcare provider is assessing vital signs in pediatric patients. Which of the following vital signs is abnormal?

• A. 11-year-old male: 90 BPM, 22 RPM, 100/70 mmHg
• B. 13-year-old female: 105 BPM, 22 RPM, 105/50 mmHg
• C. 5-year-old male: 102 BPM, 24 RPM, 90/65 mmHg
• D. 6-year-old female: 100 BPM, 26 RPM, 90/70 mmHg

Correct answer: B

Rationale: The normal range of vital signs for pediatric patients varies with age. For 11 to 14-year-olds, the normal vital sign ranges are: Heart rate: 60-105 BPM; Respiratory rate: 12-20 RPM; Blood pressure: Systolic 85-120 mmHg, Diastolic 55-80 mmHg. The 13-year-old female in choice B has a diastolic blood pressure below the normal range, indicating hypotension. Additionally, her heart rate is at the upper limit of normal, and her respiratory rate is within normal limits. Choices A, C, and D all fall within the normal ranges for vital signs in pediatric patients.

5. A patient in the emergency room has a fractured left elbow and presents with an unequal radial pulse, swelling, and numbness in the left hand after waiting for 5 hours. What is the nurse's priority intervention?

• A. Place the patient in a supine position
• B. Ask the patient to rate his pain on a scale of 1 to 10.
• C. Wrap the fractured area with a snug dressing
• D. Start an IV in the other arm.

Correct answer: D

Rationale: The correct answer is to start an IV in the other arm. In this scenario, the patient is showing signs of Acute Compartment Syndrome, a serious condition that occurs due to increased pressure within a muscle compartment, leading to decreased blood flow and potential tissue damage. Starting an IV is crucial as the patient may require emergency surgery, such as a fasciotomy, to relieve the pressure and prevent further complications. Placing the patient in a supine position, asking about pain levels, or wrapping the fractured area, though important, are not the priority interventions in this critical situation where immediate medical intervention is necessary to prevent irreversible damage or loss of limb.
