Correct Answer: A

Rationale: The presentation described is characteristic of acute angle-closure glaucoma. This condition typically presents with sudden-onset severe eye pain, headache, nausea, and vomiting. On examination, the affected eye may appear red due to conjunctival injection, and there may be a steamy cornea due to corneal edema. The mid-dilated, non-reactive pupil is a key finding in angle-closure glaucoma, as the iris bombe (forward movement of the peripheral iris) blocks the drainage angle, leading to increased intraocular pressure. If left untreated, acute angle-closure glaucoma can result in irreversible vision loss. Immediate intervention is crucial to lower the intraocular pressure and prevent further damage to the optic nerve. Prompt referral to an ophthalmologist for definitive treatment is necessary in cases of suspected acute angle-closure glaucoma.

Correct Answer: C

Rationale: Patients prescribed proton pump inhibitors (PPIs) for gastroesophageal reflux disease (GERD) should be instructed to take the medication 30 minutes before meals. This is because PPIs work best when taken on an empty stomach, allowing them to inhibit the gastric proton pump effectively and reduce acid production in anticipation of food intake. Taking the medication before meals ensures optimal absorption and effectiveness in controlling symptoms of GERD.

Correct Answer: B

Rationale: In a stratified sampling method, the population is divided into subgroups or strata based on certain characteristics that are relevant to the research objective. This allows for representation from each subgroup in the sample, ensuring that different segments of the population are taken into account.

Correct Answer: A

Rationale: It is recommended for nurses to conduct physical assessments on school children at least three times a year, or thrice a year. This frequency allows nurses to monitor the children's growth and development, assess any changes in their health status, and provide early intervention if needed. Regular physical assessments help ensure that any health issues are identified promptly and addressed appropriately, promoting the overall well-being and academic performance of the students.

Correct Answer: C

Rationale: The priority item that should be placed at the newborn's bedside is a blood pressure cuff. Monitoring the newborn's blood pressure is crucial in the NICU, as it helps assess the baby's cardiovascular function and overall well-being. Blood pressure changes can be an early indication of potential health issues, so having a blood pressure cuff readily available allows for timely monitoring and intervention if necessary. The other items listed (specific gravity urinometer, rectal thermometer, bottle of sterile normal saline) are also important in neonatal care, but monitoring blood pressure takes precedence in this scenario.
