Structures passing through the carpal tunnel into the hand include which of the following?

Correct Answer: C

Rationale: The correct answer is C: The median nerve. The carpal tunnel is a narrow passageway in the wrist where the median nerve and nine flexor tendons pass through. The median nerve is responsible for providing sensory and motor functions to the thumb, index, and middle fingers. The ulnar nerve passes outside the carpal tunnel and innervates the ring and little fingers. The radial nerve also does not pass through the carpal tunnel, as it supplies motor function to the muscles of the forearm. The five finger flexor tendons pass through the carpal tunnel along with the median nerve, but the question specifically asks for structures passing through, making C the correct answer.

Correct Answer: A

Rationale: Step-by-step rationale: 1. Intuition is the correct answer because it refers to the subconscious processing of assessment data by expert nurses. 2. Expert nurses rely on intuition to make quick and accurate decisions based on their experience and pattern recognition. 3. Intuition allows nurses to act without consciously labeling or analyzing the assessment data. 4. The nursing process (B) involves a systematic approach to care, not necessarily based on subconscious responses. 5. Clinical knowledge (C) is important but does not specifically refer to the subconscious pattern recognition seen in intuition. 6. Diagnostic reasoning (D) involves a more deliberate and analytical process compared to the quick, pattern-based responses of intuition. Summary: Intuition is the correct choice as it describes the subconscious response of expert nurses to assessment data. The other options, the nursing process, clinical knowledge, and diagnostic reasoning, do not specifically capture the automatic, pattern-based nature of expert nurse responses.

Correct Answer: D

Rationale: The correct answer is D because teaching nurses how to conduct electronic searches for research studies empowers them to independently access relevant information efficiently. This approach promotes self-directed learning and increases the likelihood of incorporating evidence-based practice (EBP) into their daily routines. Forming a committee (A) may not address immediate needs, posting studies on bulletin boards (B) may not be practical or up-to-date, and visiting the library (C) may not be convenient or time-effective for all nurses.

Correct Answer: B

Rationale: The correct answer is B: High frequency, low intensity. High-frequency TENS (typically 80-100 Hz) is effective for acute pain by stimulating the release of endorphins and enkephalins, blocking pain signals. Low-intensity avoids muscle contraction, providing pain relief without discomfort. High intensity may cause muscle contractions and discomfort. Low frequency (2-10 Hz) TENS is more suitable for chronic pain, not as effective for acute pain.

Correct Answer: C

Rationale: The correct answer is C: Right homonymous hemianopsia. This term describes the loss of vision on the same side in both eyes. In this case, the patient is unable to see on the entire right side with either eye covered, indicating a lesion in the left optic tract or radiation. A: Bitemporal hemianopsia is a loss of vision from the outer half of both visual fields, typically due to a pituitary tumor compressing the optic chiasm. B: Right temporal hemianopsia refers to a loss of vision on the right side of both visual fields, which is not consistent with the patient's presentation. D: Binasal hemianopsia is characterized by a loss of vision on the inner half of both visual fields, usually seen in pituitary tumors involving the optic chiasm.
