Nokea
A patient presents with sudden-onset, severe eye pain, headache, nausea, and vomiting. On examination, the affected eye appears red, with a steamy cornea and mid-dilated, non-reactive pupil. Which of the following conditions is most likely responsible for this presentation?
- A. Acute angle-closure glaucoma
- B. Central retinal artery occlusion
- C. Optic neuritis
- D. Corneal ulcer
Correct Answer: A
Rationale: The presentation described is consistent with acute angle-closure glaucoma. This condition typically presents with sudden-onset severe eye pain, headache, nausea, and vomiting. On examination, the affected eye appears red, with a steamy cornea due to corneal edema and a mid-dilated, non-reactive pupil due to pupillary block from the forward displacement of the iris. Acute angle-closure glaucoma is considered a medical emergency as it can lead to permanent vision loss if not promptly treated. Prompt management involves reducing intraocular pressure to prevent further damage to the optic nerve.

Which information about the nature of dengue fever the nurse should relay to the community?
- A. It is always life threatening
- B. It could be deadly but preventable
- C. It could responds well to antibiotics
- D. The incubation period is variable
Correct Answer: B
Rationale: The correct information about the nature of dengue fever that the nurse should relay to the community is that it could be deadly but preventable. Dengue fever is a viral infection spread by mosquitoes, particularly the Aedes aegypti mosquito. While many cases of dengue fever are mild, it can also lead to severe dengue, which can be life-threatening if not properly managed. However, preventive measures such as using mosquito repellent, wearing protective clothing, and eliminating breeding sites for mosquitoes can significantly reduce the risk of contracting dengue fever. Therefore, it is important for the community to be aware that while dengue fever can be deadly, it is also preventable with appropriate measures.
You encounter a conscious adult choking on a piece of food. The person is coughing forcefully but unable to speak or breathe effectively. What is the most appropriate action?
- A. Encourage continued coughing.
- B. Perform abdominal thrusts (Heimlich maneuver).
- C. Deliver back blows.
- D. Administer rescue breaths.
Correct Answer: B
Rationale: The most appropriate action in this situation is to perform abdominal thrusts, also known as the Heimlich maneuver. This technique is used to clear a blocked airway caused by a choking obstruction. Encouraging continued coughing may not be effective if the person is unable to dislodge the obstruction on their own. Delivering back blows can sometimes be effective, but abdominal thrusts are more commonly recommended in cases of choking in adults. Administering rescue breaths is not recommended if the person is conscious and able to cough, as it may worsen the situation by pushing the obstruction further down. By quickly performing abdominal thrusts, you can help dislodge the obstruction and potentially save the person's life.
A patient with a history of coronary artery disease is prescribed aspirin for secondary prevention. Which adverse effect is a potential concern with long-term aspirin therapy?
- A. Thrombocytopenia
- B. Gastrointestinal bleeding
- C. Hypercholesterolemia
- D. Hypertension
Correct Answer: B
Rationale: Long-term aspirin therapy, especially at higher doses, can increase the risk of gastrointestinal bleeding. Aspirin irreversibly inhibits cyclooxygenase enzyme, which is essential for the production of prostaglandins involved in mucosal protection of the gastrointestinal tract. Without these protective prostaglandins, the stomach lining becomes more susceptible to damage from gastric acid, leading to potential ulcer formation and bleeding. Patients with a history of coronary artery disease may be on aspirin for secondary prevention, and it is crucial to monitor for signs of bleeding such as black, tarry stools or abdominal pain. The benefits of aspirin in preventing cardiovascular events need to be weighed against the risk of adverse effects like gastrointestinal bleeding, especially in patients on long-term therapy.
The diagnostic examination for osteoporosis is geared towards measuring
- A. Bone density
- B. Weight
- C. Blood volume
- D. Height
Correct Answer: A
Rationale: The diagnostic examination for osteoporosis typically involves measuring bone density. This is usually done through a dual-energy x-ray absorptiometry (DEXA) scan, which is considered the gold standard for assessing bone density. Osteoporosis is characterized by decreased bone mass and deterioration of bone tissue, leading to increased bone fragility and risk of fractures. Measuring bone density helps in diagnosing osteoporosis by identifying areas of low bone density, assessing the risk of fractures, and monitoring the effectiveness of treatment. Weight, blood volume, and height are not directly used as primary indicators for diagnosing osteoporosis.
Some postpartum mothers will experience difficulty voiding because of the edema and trauma of the perineum. Which PRIORITY nursing measures stimulate the sensation of voiding?
- A. Encouraging her to void.
- B. Running water in the sink or shower.
- C. Helping the mother into the shower.
- D. providing cold tea or fluids of choice.
Correct Answer: B
Rationale: Running water in the sink or shower is a priority nursing measure to stimulate the sensation of voiding in postpartum mothers experiencing difficulty due to edema and trauma of the perineum. The sound and sight of running water can help relax the pelvic floor muscles and trigger the urge to void. This technique is commonly used in clinical practice to facilitate voiding and prevent urinary retention in postpartum women.
