Nokea
These medications are prescribed by the health care provider for a patient who has just been admitted to hospital with acute angle-closure glaucoma. Which of the following medications should the nurse give first?
- A. Morphine sulphate 4 mg intravenously
- B. Betaxolol 1 drop in each eye
- C. Acetazolamide 250 mg orally
- D. Mannitol 100 mg intravenously
Correct Answer: D
Rationale: The most immediate concern for the patient is to lower intraocular pressure, which will occur most rapidly with IV administration of a hyperosmolar diuretic such as mannitol. The other medications also are appropriate for a patient with glaucoma but would not be the first medication administered.

The nurse is admitting a patient with a head injury after a motor vehicle accident who has shortness of breath and severe eye pain. Which of the following actions should the nurse take first?
- A. Elevate the head to 45 degrees.
- B. Administer the ordered analgesic.
- C. Check the patient's oxygen saturation.
- D. Examine the eye for evidence of trauma.
Correct Answer: C
Rationale: The priority action for a patient after a head injury is to assess and maintain airway and breathing. Because the patient is complaining of shortness of breath, it is essential that the nurse assess the oxygen saturation. The other actions also are appropriate but are not the first action the nurse will take.
A patient with hearing loss asks the nurse about the use of a cochlear implant. Which of the following information will the nurse include when replying to the patient?
- A. Cochlear implants require training in order to receive the full benefit.
- B. Cochlear implants are not useful for patients with congenital deafness.
- C. Cochlear implants are most helpful as an early intervention for presbycusis.
- D. Cochlear implants improve hearing in patients with conductive hearing loss.
Correct Answer: A
Rationale: Extensive rehabilitation is required after cochlear implants in order for patients to receive the maximum benefit. Hearing aids, rather than cochlear implants, are used initially for presbycusis. Cochlear implants are used for sensorineural hearing loss and would not be helpful for conductive loss. They are appropriate for some patients with congenital deafness.
Which of the following interventions should the nurse implement for a patient who has just been diagnosed with viral conjunctivitis?
- A. Explain the purpose of antiviral eye drops.
- B. Show how to perform eye irrigation safely.
- C. Instruct about how to insert soft contact lenses.
- D. Demonstrate appropriate handwashing technique.
Correct Answer: D
Rationale: Good hand hygiene is the major means to prevent the spread of conjunctivitis. Antiviral drops and eye irrigation will not be helpful in shortening the disease process. Contact lenses should not be used when patients have conjunctivitis because they can further irritate the conjunctiva.
The nurse is assessing the presence or absence of contact lenses in an unconscious patient. Which of the following directions should the nurse shine a pen light?
- A. Parallel to the eye
- B. At a 90-degree angle to the eye
- C. Obliquely into the eye
- D. Toward the centre of the nasal bridge
Correct Answer: C
Rationale: The nurse must know whether the patient has contact lenses in and assesses the eye by shining a light obliquely on the eyeball to help the nurse visualize a contact lens.

- A. Saline irrigation of the eyes
- B. Surgical removal of the lesion

- D. The use of cool compresses to the eyes
Correct Answer: C
Rationale: Baby shampoo is used to soften and remove crusts associated with blepharitis. The other interventions are not used in treating this disorder.
