1. Rehabilitation after illness is classified under which level of healthcare?

• A. Primary
• B. Secondary
• C. Tertiary
• D. All three

Correct answer: C

Rationale: Rehabilitation after illness is classified as tertiary care. Tertiary care aims to help patients recover from illness, injuries, or disabilities, and restore their functionality. Primary care involves preventive measures and early disease detection, while secondary care focuses on diagnosis and treatment of specific conditions. Therefore, choices A, B, and D are incorrect as they do not specifically address the specialized nature of rehabilitation in healthcare.

2. At one minute after birth, an infant is crying, has a heart rate of 140, has acrocyanosis, resists the suction catheter, and keeps his arms extended and his legs flexed. What is the Apgar score?

• A. 4
• B. 6
• C. 8
• D. 10

Correct answer: C

Rationale: The Apgar score is based on five components: heart rate, respiratory effort, muscle tone, reflex irritability, and color. In this case, the infant has a heart rate over 100 (2 points), is crying (2 points indicating good respiratory effort), resists the catheter (2 points for good reflex irritability), but has acrocyanosis (partial point deduction of 1). Thus, the Apgar score at one minute after birth would be 8. Choice A is incorrect as the given signs indicate a higher score. Choice B is incorrect as the signs described support a score above 6. Choice D is incorrect as it represents a perfect score which is not the case here due to acrocyanosis.

3. What is the primary function of surfactant in the lungs?

• A. Reduce surface tension
• B. Enhance oxygen absorption
• C. Facilitate carbon dioxide release
• D. Increase lung volume

Correct answer: A

Rationale: The primary function of surfactant in the lungs is to reduce surface tension in the alveoli. This reduction in surface tension prevents lung collapse and allows for easier breathing. It is particularly crucial in premature infants to help with lung expansion. Choice B is incorrect because surfactant primarily affects surface tension, not oxygen absorption. Choice C is incorrect because surfactant's main role is not in facilitating carbon dioxide release. Choice D is incorrect because surfactant does not directly increase lung volume; its main role is in reducing surface tension.

4. The PN identifies an electrolyte imbalance, exhibited by changes in mental status, and an elevated blood pressure for a client with progressive heart disease. Which intervention should the PN implement first?

• A. Record usual eating patterns
• B. Evaluate for muscle cramping
• C. Document abdominal girth
• D. Elevate both legs on pillows

Correct answer: B

Rationale: Evaluating for muscle cramping, which is a sign of electrolyte imbalance, is crucial in this scenario. Electrolyte imbalances, especially involving potassium or calcium, can lead to serious complications such as arrhythmias or seizures, which need immediate attention. Recording eating patterns (choice A) may be important for overall assessment but is not the priority in this situation. Documenting abdominal girth (choice C) and elevating legs on pillows (choice D) are not directly related to addressing the immediate concern of electrolyte imbalance and its potential complications.

5. What is the primary function of hemoglobin in red blood cells?

• A. Oxygen transport
• B. Immunity
• C. Blood clotting
• D. Carbon dioxide transport

Correct answer: A

Rationale: The correct answer is A: Oxygen transport. Hemoglobin in red blood cells binds to oxygen in the lungs and carries it to tissues throughout the body, releasing it where needed. This process is essential for cellular respiration and energy production. Choices B, C, and D are incorrect because hemoglobin's primary function is not related to immunity, blood clotting, or carbon dioxide transport. Hemoglobin's main role is to transport oxygen, ensuring adequate oxygen supply to body tissues for metabolic processes.
