A patient presents with painless, progressive visual field loss, particularly in the peripheral vision, in both eyes. Gonioscopy reveals an open iridocorneal angle. Which of the following conditions is most likely responsible for this presentation?
- A. Open-angle glaucoma
- B. Closed-angle glaucoma
- C. Age-related macular degeneration
- D. Diabetic retinopathy
Correct Answer: A
Rationale: The presentation of painless, progressive visual field loss, especially in the peripheral vision, along with an open iridocorneal angle is characteristic of open-angle glaucoma. Open-angle glaucoma is a type of glaucoma where there is no physical obstruction to the outflow of aqueous humor from the eye, but there is gradual damage to the optic nerve over time. The gradual loss of peripheral vision is a common early symptom of open-angle glaucoma. It is essential to diagnose and manage open-angle glaucoma promptly to prevent irreversible vision loss.

A patient with a history of stroke is at risk for impaired skin integrity due to immobility. Which nursing intervention is most effective in preventing pressure ulcers in this patient?
- A. Turning and repositioning the patient every 2 hours
- B. Massaging bony prominences regularly
- C. Applying heating pads to areas of erythema
- D. Using a pressure-reducing mattress
Correct Answer: A
Rationale: Turning and repositioning the patient every 2 hours is the most effective nursing intervention in preventing pressure ulcers in a patient with a history of stroke and immobility. Pressure ulcers, also known as bedsores, are caused by prolonged pressure on the skin, leading to reduced blood flow and tissue damage. By regularly turning and repositioning the patient, pressure is relieved from specific areas of the body, helping to prevent the development of pressure ulcers. This intervention helps to redistribute pressure, improve blood flow, and reduce the risk of skin breakdown, thus promoting skin integrity in immobile patients.
The immunity conferred by tetanus toxoid is best described as:
- A. Lifelong passive
- B. Temporary passive
- C. Long-lasting active
- D. Lifelong active
Correct Answer: C
Rationale: Tetanus toxoid provides long-lasting active immunity. When a person is vaccinated with tetanus toxoid, their immune system is stimulated to produce antibodies against the tetanus toxin. These antibodies provide protection against tetanus infection by recognizing and neutralizing the toxin if the person is exposed to the bacteria that causes tetanus in the future. This active immune response can last for many years, providing ongoing protection against tetanus. However, booster doses are recommended every 10 years to maintain adequate levels of protection.
A pregnant woman presents with sudden onset of severe abdominal pain and vaginal bleeding. On examination, her abdomen is rigid, and fetal parts are palpable abdominally. Which of the following conditions is the most likely cause of these symptoms?
- A. Ectopic pregnancy
- B. Pelvic inflammatory disease
- C. Uterine rupture
- D. Ovarian torsion
Correct Answer: C
Rationale: Uterine rupture is the most likely cause of these symptoms in a pregnant woman presenting with sudden onset of severe abdominal pain, vaginal bleeding, rigidity of the abdomen, and palpable fetal parts abdominally. Uterine rupture is a rare but serious complication of pregnancy, typically occurring during labor in women with a previous cesarean delivery or other uterine scars. The sudden onset of severe abdominal pain can be associated with vaginal bleeding due to the tearing of the uterine wall, causing fetal parts to be palpable abdominally. This is a life-threatening emergency that requires immediate medical intervention. Ectopic pregnancy, pelvic inflammatory disease, and ovarian torsion may present with abdominal pain and vaginal bleeding but would not typically present with palpable fetal parts abdominally in a pregnant woman.
During a support group meeting, Nurse Donato, in a teasing manner, has made several provocative remarks about your appearance and behavior as a group leader. Select your MOST appropriate response.
- A. "Donato, see me after this meeting"
- B. "Donato, you are excused from the group"
- C. "What do you think Donato is trying to tell us?"
- D. "Donato, what are you saying is inappropriate"
Correct Answer: D
Rationale: Choosing option D, "Donato, what you are saying is inappropriate," is the most appropriate response in this situation. It directly addresses Nurse Donato's behavior without escalating the situation or being overly confrontational. By calmly pointing out that the remarks are inappropriate, you are setting a boundary and letting Nurse Donato know that such behavior is not acceptable in a professional setting. This response also signals to the rest of the group that you are aware of the inappropriate comments and are taking action to address them. It is important to address such behavior professionally and assertively to maintain a respectful and supportive environment during the support group meeting.
A patient presents with recurrent episodes of sudden, severe vertigo lasting hours, accompanied by nausea, vomiting, and nystagmus. Vestibular function tests demonstrate unilateral weakness. Which of the following conditions is most likely responsible for this presentation?
- A. Vestibular neuritis
- B. Benign paroxysmal positional vertigo (BPPV)
- C. Ménière's disease
- D. Acoustic neuroma
Correct Answer: A
Rationale: The patient's presentation of recurrent episodes of sudden, severe vertigo lasting hours, along with nausea, vomiting, nystagmus, and unilateral weakness on vestibular function tests, is most consistent with vestibular neuritis. Vestibular neuritis is an inflammatory disorder of the vestibular nerve, typically viral in origin, leading to acute onset of vertigo. Patients often experience severe vertigo, imbalance, nausea, and vomiting, along with characteristic nystagmus. Unilateral weakness on vestibular function testing supports the diagnosis of vestibular neuritis, as it indicates dysfunction of one vestibular organ. Benign paroxysmal positional vertigo (BPPV) typically presents with brief episodes of vertigo triggered by changes in head position without associated unilateral vestibular weakness. Ménière's disease is characterized by recurrent episodes of vertigo associated with fluctuating hearing loss, tinnitus, and aural fullness, and
