Nursing Elites

1. 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).

2. A client is recovering from a craniotomy and has a ventriculostomy in place. The nurse notices the drainage from the ventriculostomy is suddenly increasing. What should the nurse do first?

• A. Increase the head of the bed to 45 degrees.
• B. Clamp the ventriculostomy tube.
• C. Notify the healthcare provider immediately.
• D. Measure the client's head circumference.

Correct answer: C

Rationale: A sudden increase in drainage from a ventriculostomy could indicate a serious complication such as increased intracranial pressure or hemorrhage. The priority action in this situation is to notify the healthcare provider immediately to ensure prompt evaluation and intervention. Increasing the head of the bed may be beneficial in some situations but is not the first action to take. Clamping the ventriculostomy tube is inappropriate as it can lead to increased intracranial pressure. Measuring the client's head circumference is not the priority when there is a sudden increase in ventriculostomy drainage.

3. A client has a prescription for a transcutaneous electrical nerve stimulator (TENS) unit for pain management during the postoperative period following a lumbar laminectomy. Which information should the nurse reinforce about the action of this adjuvant pain modality?

• A. The discharge of electricity will distract the client's focus from the pain
• B. An infusion of medication in the spinal canal will block pain perception
• C. Pain perception in the cerebral cortex is dulled by the unit's discharge of an electrical stimulus
• D. A mild electrical stimulus on the skin surface closes the gates of nerve conduction for severe pain

Correct answer: D

Rationale: The correct answer is D. TENS works by delivering a mild electrical stimulus to the skin, which can help close the 'gates' in the nervous system to block pain signals from reaching the brain, thus reducing pain perception. Choice A is incorrect because TENS does not distract from pain but rather helps manage it. Choice B is incorrect as it describes a different pain management technique involving medication in the spinal canal. Choice C is incorrect because TENS acts peripherally on nerve conduction rather than dulling pain perception in the cerebral cortex.

4. Which of the following is a critical step in preventing ventilator-associated pneumonia (VAP)?

• A. Performing oral care with chlorhexidine
• B. Elevating the head of the bed to 30-45 degrees
• C. Administering prophylactic antibiotics
• D. Changing the ventilator circuit daily

Correct answer: B

Rationale: Elevating the head of the bed to 30-45 degrees is a critical step in preventing ventilator-associated pneumonia (VAP) because it helps reduce the risk of aspiration, which is a significant factor in the development of VAP. Elevating the head of the bed enhances pulmonary hygiene, decreases the risk of microaspiration, and promotes better lung function. Performing oral care with chlorhexidine is essential for oral hygiene but is not specifically aimed at preventing VAP. Administering prophylactic antibiotics without a clear indication can lead to antibiotic resistance and is not a recommended routine practice to prevent VAP. Changing the ventilator circuit daily is essential for infection control but is not the most critical step in preventing VAP.

5. When caring for a patient with a fresh tracheostomy, what is the nurse’s first priority?

• A. Providing humidified oxygen
• B. Ensuring the tracheostomy ties are secure
• C. Suctioning the tracheostomy tube as needed
• D. Monitoring for signs of infection

Correct answer: B

Rationale: The correct answer is B: Ensuring the tracheostomy ties are secure. This is the nurse's first priority because it is critical to prevent accidental decannulation, which could compromise the patient’s airway. Providing humidified oxygen, suctioning the tracheostomy tube, and monitoring for signs of infection are important aspects of care but ensuring the tracheostomy ties' security takes precedence to maintain the patient's airway.
