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).

The PN assigns a UAP to assist with the personal care of a client experiencing an acute exacerbation of multiple sclerosis. Which instruction should the PN provide the UAP?
- A. Assist the client with a hot bath
- B. Encourage self-care but allow rest periods
- C. Face the client directly when speaking
- D. Keep the head of the bed elevated at all times
Correct Answer: B
Rationale: During an acute exacerbation of multiple sclerosis, it is important to encourage self-care to maintain the client's independence. Allowing rest periods helps prevent fatigue, which is crucial in managing MS exacerbations. Choice A is incorrect as hot baths can exacerbate symptoms in MS. Choice C is about communication techniques and not directly related to client care during an exacerbation. Choice D is not a priority intervention during an MS exacerbation.
Inspiratory and expiratory stridor may be heard in a client who:
- A. Is experiencing an exacerbation of goiter
- B. Is experiencing an acute asthmatic attack
- C. Has aspirated a piece of meat
- D. Has severe laryngotracheitis
Correct Answer: D
Rationale: Inspiratory and expiratory stridor are high-pitched, wheezing sounds caused by disrupted airflow due to airway obstruction. Severe laryngotracheitis, involving inflammation and swelling of the larynx and trachea, leads to airway obstruction and can produce both inspiratory and expiratory stridor. Exacerbation of goiter, an acute asthmatic attack, and aspiration of a piece of meat are not typically associated with both inspiratory and expiratory stridor. Therefore, choices A, B, and C are incorrect.
Which of the following best describes the role of insulin in the body?
- A. Insulin helps break down glucose into energy for the body
- B. Insulin facilitates the movement of glucose into cells
- C. Insulin converts excess glucose into fat for storage
- D. Insulin increases the breakdown of protein into amino acids
Correct Answer: B
Rationale: The correct answer is B: Insulin facilitates the movement of glucose into cells. Insulin is a hormone that helps regulate blood sugar levels by promoting the uptake of glucose from the bloodstream into cells, where it can be used for energy production. Choice A is incorrect because insulin doesn't break down glucose but rather helps cells take up glucose. Choice C is incorrect as insulin does not directly convert glucose into fat; excess glucose is stored as fat by other processes. Choice D is incorrect as insulin does not increase the breakdown of protein into amino acids; its primary role is in glucose metabolism.
A client is admitted to the postoperative surgical unit with two test tubes after a left lobectomy. The nurse observed that the chambers are set at the prescribed suction of 20 cm water pressure, and tidying occurs with respirations and bubbling. What action should the nurse implement?
- A. Clamp the chest tube to see if the bubbling activity stops
- B. Notify the registered nurse of the observed bubbling
- C. Maintain system integrity to promote lung reexpansion
- D. Apply an occlusive dressing to the chest
Correct Answer: C
Rationale: Maintaining system integrity is essential to promote lung reexpansion in postoperative patients with chest tubes. Clamping the chest tube abruptly can lead to tension pneumothorax, a life-threatening condition. The bubbling observed is a normal sign indicating that the system is functioning correctly, as it allows the drainage of air or fluid from the pleural space. Notifying the registered nurse may be necessary if there are significant concerns or changes observed, but the immediate action should be to ensure system integrity and lung reexpansion.
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 PN reinforce about the action of the adjuvant pain modality?
- A. The discharge of electricity will distract the client's focus from the pain.
- B. An infusion of medication into 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 TENS unit works by providing a mild electrical stimulus to the skin, which helps to 'close the gate' on pain signals, reducing the perception of pain. Choice A is incorrect because distraction is not the primary mechanism of action for TENS. Choice B is incorrect as it describes a different method of pain management involving medication infusion into the spinal canal. Choice C is incorrect as it inaccurately describes the location of pain perception modulation by the TENS unit.
