The nurse is caring for a client who has recently had a cerebrovascular accident (CVA). When positioning the client and supporting her extremities, the nurse must remember that when voluntary control of muscles is lost:
- A. the feet will maintain a position of eversion.
- B. the upper extremities will rotate externally.
- C. the hip joint will rotate internally.
- D. flexor muscles will become stronger than extensors.
Correct Answer: D
Rationale: After a CVA, flexor muscles become stronger than extensors, leading to flexion contractures, requiring careful positioning to prevent deformities.
The client recently diagnosed with age-related macular degeneration (AMD) in both eyes returns to the clinic for a follow-up appointment. Which assessment will the nurse be certain to include during the visit?
- A. Stools for occult blood
- B. Blood glucose levels
- C. Screening for depression
- D. Screening for hearing loss
Correct Answer: C
Rationale: The nurse should assess for depression because loss of vision can affect functional ability, mood, and quality of life. Depression frequently develops within a few months after AMD is diagnosed in both eyes. GI bleeding, blood glucose, and hearing loss are not directly related to AMD.
During an assessment, the nurse covers the client's right eye and then observes a shift in the client's gaze after the eye is uncovered. Which conclusion should the nurse make about the results of the test?
- A. The client has opacity of the lens.
- B. The client has absence of the blink reflex.
- C. The client has increased intraocular pressure.
- D. The client has weakness in the extraocular muscles.
Correct Answer: D
Rationale: Covering and then uncovering the client's eye and then observing for a shift in the client's gaze is the cover-uncover test used to detect weakness in the extraocular muscles. Lens opacity is detected by direct observation. Stroking the eyelashes will evoke the blink reflex. The intraocular pressure is measured by tonometry.
The client following removal of a right-sided acoustic neuroma by a translabyrinthine approach calls the nurse to report pain. The nurse finds that the client has new-onset right-sided facial drooping and numbness. Place the nurse's actions in priority order.
- A. Close the client's right eye and place a patch over it.
- B. Assess the operative incision site and assess the arms for drift.
- C. Contact the stroke team and the HCP.
- D. Medicate the client for pain unless contraindicated.
Correct Answer: B,C,D,A
Rationale: Assess the incision and arms for drift first (B), then contact the stroke team and HCP for possible complications (C), medicate for pain (D), and finally patch the eye due to inability to close it (A).
The student nurse asks the nurse, 'Which type of hearing loss involves damage to the cochlea or vestibulocochlear nerve?' Which statement is the best response of the nurse?
- A. It is called conductive hearing loss.
- B. It is called a functional hearing loss.
- C. It is called a mixed hearing loss.
- D. It is called sensorineural hearing loss.
Correct Answer: D
Rationale: Sensorineural hearing loss involves cochlear or vestibulocochlear nerve damage. Conductive loss affects the outer/middle ear, functional loss is psychological, and mixed involves both.
