Which statement about glaucoma is true and accurate?
- A. Acute angle-closure glaucoma is an ocular emergency.
- B. Acute angle-closure glaucoma leads to the loss of peripheral vision and tunnel vision.
- C. Primary open-angle glaucoma leads to eye pain, nausea, and vomiting, blurry vision, and halos.
- D. Bubbles are implanted to protect the retina from glaucoma.
Correct Answer: A
Rationale: The correct answer is A: 'Acute angle-closure glaucoma is an ocular emergency.' Acute angle-closure glaucoma is indeed considered an ocular emergency that requires immediate attention to prevent vision loss. Choice B is incorrect because acute angle-closure glaucoma commonly presents with symptoms like severe eye pain, headache, blurred vision, and halos around lights. Choice C is incorrect as these symptoms are more indicative of acute angle-closure glaucoma rather than primary open-angle glaucoma. Choice D is incorrect since bubbles are not typically used to protect the retina from glaucoma; treatment usually involves medications, laser therapy, or surgery to manage intraocular pressure.

A nurse is caring for a client who wanders through the halls yelling obscenities at staff, other clients, and visitors. Which of the following actions should the nurse take?
- A. Keep the client in their room with the door closed
- B. Contact a family member to come and sit with the client
- C. Place the client in a wheelchair with a lap tray
- D. Administer a sedative to the client
Correct Answer: B
Rationale: When dealing with a client exhibiting disruptive behavior like yelling obscenities, involving a family member can provide emotional support and help in de-escalating the situation. Keeping the client isolated in their room (Choice A) may lead to further agitation. Placing the client in a wheelchair (Choice C) or administering a sedative (Choice D) should not be the first interventions for managing behavioral issues.
Which of the following is the best argument for lower patient-to-nurse ratio?
- A. The more patients a nurse has, the better the nurse will be at catching early warning signs.
- B. Greater patient-to-nurse ratios decrease patient mortality.
- C. Adequate nurse levels do not impact the prevalence of urinary tract infections.
- D. Community nursing ratios do not impact Methicillin-resistant Staphylococcus aureus (MRSA) rates.
Correct Answer: B
Rationale: The best argument for lower patient-to-nurse ratios is that they decrease patient mortality. Choice A is incorrect because having more patients can lead to increased workload and decreased attention per patient. Choice C is incorrect as adequate nurse levels can indeed impact the prevalence of infections. Choice D is incorrect as community nursing ratios can impact MRSA rates due to potential transmission risks in healthcare settings.
Which manifestation should the nurse expect to assess in a patient with fluid volume deficit?
- A. Headache and muscle cramps
- B. Dyspnea and respiratory crackles
- C. Increased pulse rate and blood pressure
- D. Orthostatic hypotension and flat neck veins
Correct Answer: D
Rationale: Orthostatic hypotension and flat neck veins are classic manifestations of fluid volume deficit. When the body loses fluid, blood volume decreases, leading to decreased venous return to the heart, resulting in orthostatic hypotension and flat neck veins. Choices A, B, and C are more indicative of other conditions such as dehydration, respiratory issues, or compensatory mechanisms in response to hypovolemia, respectively.
Round off these numbers to the nearest tenth:
- A. 5.5778 = 5.6, 1.027 = 1.0, 62.999 = 63, 55.123 = 55.1, 96.676 = 96.7
- B. 5.5778 = 5.6, 1.027 = 1.0, 62.999 = 63, 55.123 = 55.1, 96.676 = 96.7
- C. 5.5778 = 5.6, 1.027 = 1.0, 62.999 = 63, 55.123 = 55.1, 96.676 = 96.7
- D. 5.5778 = 5.6, 1.027 = 1.0, 62.999 = 63, 55.123 = 55.1, 96.676 = 96.7
Correct Answer: B
Rationale: The correct answer is B. When rounding off to the nearest tenth, 1.027 becomes 1.0 because the digit in the hundredth's place is less than 5. For the other numbers, they are rounded correctly to the nearest tenth: 5.5778 = 5.6, 62.999 = 63, 55.123 = 55.1, 96.676 = 96.7. Therefore, option B is the most accurate in rounding off these numbers to the nearest tenth. Choices A, C, and D are incorrect as they do not round 1.027 to 1.0 as required when rounding to the nearest tenth.
What is an episiotomy?
- A. A surgical incision of the perineum to prevent tearing during delivery.
- B. Releasing the red plug from the cervix just before crowning occurs.
- C. An incision in the abdomen with which the baby can be delivered through.
- D. The severance of the umbilical cord between mother and child.
Correct Answer: A
Rationale: An episiotomy is a surgical incision of the perineum to prevent tearing during delivery. This procedure is performed to widen the vaginal opening and facilitate childbirth. Choice B is incorrect as it describes the expulsion of the mucus plug, not an episiotomy. Choice C is incorrect as it refers to a different procedure, a cesarean section, where the baby is delivered through an incision in the abdomen. Choice D is incorrect as it pertains to cutting the umbilical cord, which is not related to an episiotomy.
