1. 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.

2. Which cranial nerve is responsible for the sense of smell?

• A. Olfactory nerve
• B. Optic nerve
• C. Trigeminal nerve
• D. Vagus nerve

Correct answer: A

Rationale: The olfactory nerve (Cranial Nerve I) is indeed responsible for the sense of smell. It is located in the nasal cavity and transmits olfactory information to the brain. The optic nerve (Choice B) is responsible for vision, the trigeminal nerve (Choice C) is responsible for sensation in the face, and the vagus nerve (Choice D) is responsible for various functions such as heart rate, digestion, and speech. Therefore, the correct answer is the olfactory nerve (Choice A).

3. 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.

4. The nurse observes a UAP performing oral hygiene on an unconscious client who is lying in a flat side-lying position with an emesis basin on a towel under the chin. Which action should the nurse take?

• A. Stop the procedure and tell the UAP to place the client in a Fowler's position
• B. Praise the UAP for doing the oral hygiene but encourage family participation
• C. Tell the UAP to continue because the unconscious client is positioned safely
• D. Enroll the UAP in a hospital education class on conducting safe client care

Correct answer: C

Rationale: The correct answer is to tell the UAP to continue because the unconscious client is positioned safely for oral care. Placing an unconscious client in a side-lying position helps prevent aspiration, and having an emesis basin under the chin is appropriate to catch any fluids. Therefore, the nurse should acknowledge that the UAP is performing the procedure correctly. Choices A, B, and D are incorrect. Placing the client in a Fowler's position is not necessary for this procedure as the client is already positioned safely. Praise and encouragement for family participation are important aspects but not the immediate action needed in this scenario. Enrolling the UAP in a hospital education class is not warranted as the current procedure is being performed correctly.

5. When preparing a sterile field for a procedure, which action should the nurse take to maintain sterility?

• A. Place sterile items around the sterile field
• B. Keep hands below waist level to avoid contamination
• C. Open the sterile package away from the body
• D. Avoid reaching over the sterile field

Correct answer: D

Rationale: To maintain sterility when preparing a sterile field, it is essential to avoid reaching over the sterile field. This action can introduce contaminants from the nurse's clothing or unsterile areas, compromising the sterility of the field. Placing sterile items around the sterile field (choice A) is incorrect as it may increase the risk of contamination by extending the area where non-sterile items may come in contact. Keeping hands below waist level (choice B) is also incorrect as it does not prevent contamination effectively. Opening the sterile package away from the body (choice C) is incorrect since it exposes the contents to the nurse's body, which is not sterile.
