A nurse is assessing a client's cranial nerve function. Which of the following findings indicates an intact cranial nerve XI (accessory nerve)?
The client can follow an object with their eyes
The client can shrug their shoulders against resistance
The client can smile symmetrically
The client can identify a familiar scent with their eyes closed
The Correct Answer is B
Cranial nerve XI, the spinal accessory nerve, is a motor nerve that innervates the sternocleidomastoid and trapezius muscles. Assessment of this nerve is essential to evaluate the integrity of the cervical spinal cord and the neuromuscular pathway. Deficits may indicate central nervous system lesions or localized trauma to the neck and upper back.
A. The ability to follow an object with the eyes involves the coordinated function of cranial nerves III (oculomotor), IV (trochlear), and VI (abducens). These nerves control the extraocular muscles. While essential for a neurological exam, eye movement is not related to the function of the spinal accessory nerve.
B. To assess the accessory nerve (CN XI), the nurse asks the client to shrug their shoulders against the resistance of the nurse's hands and to turn their head side-to-side against resistance. Strong, symmetrical movement of the trapezius and sternocleidomastoid muscles confirms that the spinal accessory nerve is intact and functioning correctly.
C. Symmetrical smiling and facial expressions are controlled by cranial nerve VII, the facial nerve. This nerve innervates the muscles of facial expression and is tested by asking the client to frown, puff out their cheeks, or show their teeth. It does not provide information about the eleventh cranial nerve.
D. Identifying a familiar scent with the eyes closed is the standard test for cranial nerve I, the olfactory nerve. This is a purely sensory nerve responsible for the sense of smell. It is anatomically and functionally distinct from the motor pathways assessed during the spinal accessory nerve examination.

Correct Answer is B
Explanation
Pain is the fifth vital sign and requires immediate systematic evaluation when non-verbal cues are observed. Utilizing standardized assessment tools allows the clinician to quantify subjective experiences, guiding the multimodal analgesia approach. Prompt intervention is necessary to prevent the physiological consequences of untreated acute pain, such as tachycardia.
A. Proceeding with a full head-to-toe examination before addressing the client's obvious distress is inappropriate and lacks empathy. Pain can interfere with the client's ability to participate in a full physical assessment. Addressing the most urgent subjective concern first ensures the patient is comfortable enough for further clinical evaluation.
B. Assessing the client's level of pain using a validated scale (such as the 0 to 10 numeric scale) is the priority action. This provides a baseline to determine the severity and nature of the pain. It allows the nurse to implement interventions and later evaluate their effectiveness accurately.
C. Calling the healthcare provider before performing a thorough pain assessment is premature. The nurse must first gather data regarding the pain's location, intensity, and quality to provide a meaningful report to the provider. A complete assessment is required to ensure the correct medication and dosage are ordered.
D. Asking the family to leave does not address the immediate physiological and psychological needs of the client in pain. While privacy is important for a detailed history, it is not the priority when a patient is showing visible signs of acute discomfort. Pain management must take precedence over administrative history-taking.
Correct Answer is D
Explanation
Reasoning:
Benign prostatic hyperplasia involves the nonmalignant hypertrophy of the prostate gland, which leads to the mechanical compression of the prostatic urethra. This obstruction results in lower urinary tract symptoms (LUTS) as the bladder must work harder to overcome the resistance to urine outflow.
A. Complete bladder emptying is unlikely in a client symptomatic for BPH. The urethral obstruction typically leads to chronic urinary retention and significant post-void residual (PVR) urine. This residual volume contributes to the sensation of incomplete emptying and increases the risk of developing cystitis or bladder stones.
B. While BPH can cause a sensation of fullness or pressure, acute bladder pain is not a standard finding unless there is a secondary complication like a urinary tract infection or acute urinary retention. The progression of BPH symptoms is typically gradual and obstructive rather than acutely painful.
C. Although frequency occurs, the hallmark of the obstructive phase of BPH is the inability to initiate and maintain a strong stream. While "frequency with small amounts" describes the outcome, the most specific and universally reported nocturnal symptom that disrupts the quality of life in these patients is nocturia.
D. Nocturia is one of the most common and bothersome symptoms of BPH. As the bladder fails to empty fully during the day, residual volume builds up, and the bladder's functional capacity is reached more quickly at night. This necessitates multiple trips to the bathroom, significantly disrupting sleep patterns.
