Nursing Elites

1. In planning care for a premature infant with respiratory distress syndrome, nursing actions are based on the fact that the most likely cause of this problem stems from the infant's inability to

• A. Stabilize alveolar surface tension
• B. Maintain alveolar surface tension
• C. Promote normal pulmonary blood flow
• D. Regulate intra-cardiac pressure

Correct answer: B

Rationale: The correct answer is B: Maintain alveolar surface tension. Respiratory distress syndrome in premature infants is often caused by a deficiency in surfactant, a substance that helps maintain alveolar surface tension. Without adequate surfactant, the alveoli collapse, making it difficult for the infant to oxygenate effectively. Choices A, C, and D are incorrect because stabilizing alveolar surface tension is not the issue, promoting normal pulmonary blood flow and regulating intra-cardiac pressure are not directly related to the pathophysiology of respiratory distress syndrome in premature infants.

2. When reviewing car seat use with the parents of a 1-month-old infant, which of the following instructions should the nurse include?

• A. Use a car seat that has a three-point harness system.
• B. Position the car seat so that the infant is rear-facing.
• C. Secure the car seat in the front passenger seat of the vehicle.
• D. Convert to a booster seat after 12 months.

Correct answer: B

Rationale: The correct instruction for car seat use with a 1-month-old infant is to position the car seat so that the infant is rear-facing. This orientation provides the safest option for infants as it supports their head, neck, and spine. While using a car seat with a three-point harness system is appropriate for infants, placing the car seat in the front passenger seat is not recommended due to the presence of airbags, which can pose a risk to the infant in the event of deployment. Additionally, transitioning to a booster seat is not suitable at 12 months; infants should remain in rear-facing car seats until they outgrow the seat's height or weight limits, typically around 2 years of age.

3. A client with a history of congestive heart failure (CHF) is admitted with dyspnea and a productive cough. What is the most important assessment for the LPN/LVN to perform?

• A. Measure the client's urine output.
• B. Auscultate the client's lung sounds.
• C. Assess the client's apical pulse.
• D. Check the client's blood pressure.

Correct answer: B

Rationale: Auscultating lung sounds is crucial for assessing the extent of congestion in a client with CHF. The presence of crackles or wheezing can indicate fluid accumulation in the lungs, a common complication of CHF. Monitoring urine output (Choice A) is important to assess renal function but is not the priority in this situation. While assessing the apical pulse (Choice C) and checking blood pressure (Choice D) are important in managing CHF, they do not provide immediate information about the respiratory status and congestion level in the lungs, making auscultating lung sounds the most critical assessment.

4. During a skin assessment, a healthcare professional is observing a group of clients. Which of the following lesions should the healthcare professional identify as vesicles?

• A. Acne
• B. Warts
• C. Psoriasis
• D. Herpes simplex

Correct answer: D

Rationale: Vesicles are small fluid-filled blisters. Herpes simplex is an example of a vesicular lesion, characterized by small, fluid-filled blisters. Acne presents as comedones, papules, pustules, or nodules, not vesicles. Warts are caused by the human papillomavirus and appear as rough, raised growths. Psoriasis is a chronic autoimmune condition that results in red, scaly patches on the skin, not vesicles.

5. A client with a history of heart failure is admitted with weight gain and peripheral edema. Which medication should the LPN/LVN anticipate being prescribed?

• A. Lisinopril (Zestril)
• B. Furosemide (Lasix)
• C. Metoprolol (Lopressor)
• D. Simvastatin (Zocor)

Correct answer: B

Rationale: Furosemide (Lasix) is the correct answer. In a client with heart failure experiencing weight gain and peripheral edema, the priority is to manage fluid overload. Furosemide is a loop diuretic commonly prescribed to reduce excess fluid in heart failure patients. Lisinopril (Zestril) is an ACE inhibitor used to treat hypertension and heart failure but does not directly address fluid overload. Metoprolol (Lopressor) is a beta-blocker that helps manage heart failure symptoms but does not primarily target fluid retention. Simvastatin (Zocor) is a statin used to lower cholesterol levels and is not indicated for managing fluid overload in heart failure.
