A nurse is teaching a client about foods and beverages that can cause diarrhea. Which of the following should the nurse include in the teaching?

Choice A reason: Assessment is the first and most important phase of the nursing process, as it involves collecting and analyzing data about the patient's health status, needs, and preferences. The nurse should have assessed the patient's blood pressure before administering the antihypertensive medication, as it could have been contraindicated or required a dosage adjustment. By failing to do so, the nurse put the patient at risk of hypotension and its complications.

Choice B reason: Planning is the second phase of the nursing process, in which the nurse sets goals and outcomes for the patient's care and selects appropriate interventions. The nurse did not make an error in this phase, as the administration of the antihypertensive medication was part of the plan of care for the patient with hypertension.

Choice C reason: Diagnosis is the third phase of the nursing process, in which the nurse identifies the patient's actual or potential health problems based on the assessment data. The nurse did not make an error in this phase, as the diagnosis of hypertension was accurate and supported by the patient's history and vital signs.

Choice D reason: Evaluation is the fourth and final phase of the nursing process, in which the nurse measures the patient's progress and outcomes and modifies the plan of care as needed. The nurse did not make an error in this phase, as the re-checking of the blood pressure and the recognition of the patient's symptoms were part of the evaluation process. However, the nurse should have also notified the provider and implemented interventions to treat the hypotension.

Choice A reason: Gradual loss of peripheral vision is a characteristic symptom of open-angle glaucoma, which is the most common type of glaucoma. It occurs when the drainage angle of the eye becomes blocked, causing increased intraocular pressure and damage to the optic nerve.

Choice B reason: Gradual loss of central vision is more typical of age-related macular degeneration, which is a condition that affects the macula, the central part of the retina. It is not a symptom of open-angle glaucoma.

Choice C reason: Sudden headache and nausea are signs of acute angle-closure glaucoma, which is a medical emergency that requires immediate treatment. It occurs when the drainage angle of the eye suddenly closes, causing a rapid rise in intraocular pressure and severe pain.

Choice D reason: Cloudy blurred vision is a symptom of cataract, which is a condition that causes the lens of the eye to become cloudy and opaque. It is not a symptom of open-angle glaucoma.
