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 28-year-old male has been found wandering around in a confusing pattern. The male is sweaty and pale. Which of the following tests is most likely to be performed first?

• A. Blood sugar check
• B. CT scan
• C. Blood cultures
• D. Arterial blood gases

Correct answer: A

Rationale: In a 28-year-old male presenting with confusion, sweating, and pallor, the most likely cause is hypoglycemia, especially with no mention of trauma or infection. Therefore, the initial test to be performed should be a blood sugar check to rule out low blood sugar levels. Checking blood sugar levels is crucial in such a scenario as hypoglycemia can lead to altered mental status. A CT scan (choice B) is not typically the initial test for altered mental status without any focal neurological signs or head trauma. Blood cultures (choice C) are more relevant in cases suspected of infection, which is not a primary concern in this scenario. Arterial blood gases (choice D) may be considered later if there are concerns about respiratory status or acid-base disturbances, but in this case, checking the blood sugar level is the most immediate and appropriate action.

3. A patient is admitted to the emergency department complaining of sudden onset shortness of breath and is diagnosed with a possible pulmonary embolus. How should the nurse prepare the patient for diagnostic testing to confirm the diagnosis?

• A. Start an IV so contrast media may be given
• B. Ensure that the patient has been NPO for at least 6 hours.
• C. Inform radiology that a radioactive glucose preparation is needed
• D. Instruct the patient to undress to the waist and remove any metal objects

Correct answer: A

Rationale: For diagnosing pulmonary emboli, spiral computed tomography (CT) scans are commonly used, and contrast media may be given intravenously (IV) during the scan to enhance visualization of blood vessels. Chest x-rays are not typically diagnostic for pulmonary embolism. When preparing for a chest x-ray, the patient needs to undress and remove any metal objects. Bronchoscopy is used for examining the bronchial tree, not for assessing vascular changes, and the patient should be NPO 6 to 12 hours before the procedure. Positron emission tomography (PET) scans are primarily used to detect malignancies, and a radioactive glucose preparation is utilized for this purpose.

4. The nurse palpates the posterior chest while the patient says 99 and notes absent fremitus. What action should the nurse take next?

• A. Auscultate anterior and posterior breath sounds bilaterally
• B. Encourage the patient to turn, cough, and deep breathe
• C. Review the chest x-ray report for evidence of pneumonia
• D. Palpate the anterior chest and observe for barrel chest

Correct answer: A

Rationale: To assess for tactile fremitus, the nurse should use the palms of the hands to assess for vibration when the patient repeats a word or phrase such as '99'. After noting absent fremitus, the nurse should then auscultate the lungs to assess for the presence or absence of breath sounds. Absent fremitus may be noted with conditions like pneumothorax or atelectasis. The vibration is increased in conditions such as pneumonia, lung tumors, thick bronchial secretions, and pleural effusion. Encouraging the patient to turn, cough, and deep breathe is an appropriate intervention for atelectasis, but assessing breath sounds takes priority. Fremitus is decreased if the hand is farther from the lung or the lung is hyperinflated (barrel chest). Palpating the anterior chest for fremitus is less effective due to the presence of large muscles and breast tissue, making auscultation a more appropriate next step.

5. While planning care for a 2-year-old hospitalized child, which situation would the nurse expect to most likely affect the behavior?

• A. Strange bed and surroundings
• B. Separation from parents
• C. Presence of other toddlers
• D. Unfamiliar toys and games

Correct answer: B

Rationale: The correct answer is 'Separation from parents.' Separation anxiety is most evident from 6 months to 30 months of age and is the greatest stress imposed on a toddler by hospitalization. If separation is avoided, young children have a tremendous capacity to withstand other stress. The other choices, such as 'Strange bed and surroundings,' 'Presence of other toddlers,' and 'Unfamiliar toys and games,' may also have an impact on the child, but separation from parents is typically the most significant factor affecting behavior in a hospitalized 2-year-old.
