Nursing Elites

1. The nurse administers prescribed therapies for a patient with cor pulmonale and right-sided heart failure. Which assessment would best evaluate the effectiveness of the therapies?

• A. Observe for distended neck veins.
• B. Auscultate for crackles in the lungs.
• C. Palpate for heaves or thrills over the heart.
• D. Review hemoglobin and hematocrit values.

Correct answer: A

Rationale: To evaluate the effectiveness of therapies for cor pulmonale and right-sided heart failure, observing for distended neck veins would be the most appropriate assessment. Cor pulmonale is characterized by right ventricular failure due to pulmonary hypertension, leading to clinical manifestations such as peripheral edema, jugular venous distention, and right upper-quadrant abdominal tenderness. These signs indicate increased central venous pressure and right heart strain, which can be assessed by observing for distended neck veins. Auscultating for crackles in the lungs is more indicative of left-sided heart failure rather than right-sided heart failure. Heaves or thrills over the heart are not typically associated with cor pulmonale. Reviewing hemoglobin and hematocrit values may show elevations due to chronic hypoxemia and polycythemia in cor pulmonale, but these values alone do not directly evaluate the immediate effectiveness of the prescribed therapies on the patient's condition.

2. A 3-year-old had a hip spica cast applied 2 hours ago. In order to facilitate drying, the nurse should:

• A. Expose the cast to air and turn the child frequently.
• B. Use a heat lamp to reduce the drying time.
• C. Handle the cast with the abductor bar.
• D. Turn the child as little as possible.

Correct answer: A

Rationale: After a hip spica cast is applied, it is important to facilitate drying by exposing the cast to air and turning the child frequently, approximately every 2 hours. This helps ensure even drying and prevents skin breakdown. Using a heat lamp can cause burns and should be avoided. Handling the cast with the abductor bar is not necessary for the drying process and may cause discomfort to the child. Turning the child as little as possible is not recommended as regular turning helps prevent complications like pressure ulcers and stiffness.

3. A newborn infant in the nursery has developed vomiting, poor feeding, lethargy, and respiratory distress, and has been diagnosed with necrotizing enterocolitis. Which of the following nursing interventions is most appropriate for this infant?

• A. Feed the infant 30 cc of sterile water
• B. Position the infant on his back
• C. Administer antibiotics as ordered
• D. Allow the infant to breastfeed

Correct answer: C

Rationale: Necrotizing enterocolitis (NEC) is a serious condition characterized by ischemic bowel, leading to gastrointestinal symptoms, lethargy, poor feeding, and respiratory distress. In the management of NEC, it is crucial to stop oral feedings, insert a nasogastric tube for decompression, and administer antibiotics as prescribed by the physician. Therefore, the most appropriate nursing intervention for an infant with NEC is to administer antibiotics as ordered. Choice A, feeding the infant sterile water, is incorrect because oral feedings should be stopped in NEC. Choice B, positioning the infant on his back, is not directly related to the treatment of NEC. Choice D, allowing the infant to breastfeed, is contraindicated in NEC as oral feedings should be ceased to prevent further complications.

4. The healthcare provider is reviewing the lab results of a patient who has presented in the Emergency Room. The lab results show that the troponin T value is at 5.3 ng/mL. Which of these interventions, if not already completed, would take priority over the others?

• A. Place the patient in a 90-degree position
• B. Assess whether the patient is taking diuretics
• C. Obtain and attach defibrillator leads
• D. Assess the patient's last ejection fraction

Correct answer: C

Rationale: In this scenario, the elevated Troponin T level indicates cardiac damage, possibly due to a myocardial infarction. A Troponin T value of 5.3 ng/mL is significantly elevated (normal levels are below 0.2 ng/mL), suggesting acute cardiac injury. Given the setting of an Emergency Room and the critical nature of the situation, the priority intervention should be to obtain and attach defibrillator leads. Elevated Troponin T levels can indicate a higher risk of arrhythmias, including ventricular fibrillation, which can lead to sudden cardiac arrest. Defibrillator leads are essential for monitoring the patient's cardiac rhythm and readiness for immediate defibrillation if necessary. Placing the patient in a 90-degree position (Choice A) or assessing diuretic use (Choice B) are not immediate priorities in this critical situation. Additionally, assessing the patient's last ejection fraction (Choice D) is important but not as urgent as preparing for potential life-threatening arrhythmias requiring defibrillation.

5. A client is receiving digoxin (Lanoxin) 0.25 mg daily. The health care provider has written a new order to give metoprolol (Lopressor) 25 mg B.I.D. In assessing the client prior to administering the medications, which of the following should the nurse report immediately to the health care provider?

• A. Blood pressure 94/60 mm Hg
• B. Heart rate 76 bpm
• C. Urine output 50 ml/hour
• D. Respiratory rate 16 bpm

Correct answer: A

Rationale: The correct answer is 'Blood pressure 94/60 mm Hg.' Both digoxin and metoprolol decrease the heart rate. Metoprolol specifically affects blood pressure. Therefore, the heart rate and blood pressure need to be within normal range (HR 60-100 bpm; systolic BP above 100 mm Hg) to safely administer both medications. A blood pressure of 94/60 mm Hg indicates hypotension, which could be exacerbated by metoprolol, necessitating immediate reporting to the healthcare provider. Choices B, C, and D are within normal limits and do not pose immediate risks related to the administration of these medications.
