Rationale: The correct statement that indicates the teaching goal has been met is when the client says, "The spray should be used round-the-clock at equally spaced intervals." This statement shows an understanding of how to properly use the decongestant nasal spray as instructed by the nurse. Using the spray round-the-clock at equally spaced intervals helps maintain consistent relief from congestion without the risk of overuse or rebound effects. This response indicates that the client has grasped the correct usage instructions for the decongestant nasal spray, which is the goal of the teaching.

Correct Answer: D

Rationale: Erosion is the dental condition characterized by the destruction of tooth structure due to exposure to acidic substances, such as gastric acid from conditions like gastroesophageal reflux disease (GERD) or acidic beverages like sodas and citrus fruits. This acidic attack softens and wears away the enamel, leading to the erosion of tooth structure. Unlike dental caries, which is caused by bacteria producing acid from sugars in the mouth, erosion is primarily a result of external acidic sources. Attrition refers to the wear of tooth structure from tooth-to-tooth contact, and abrasion refers to the wear of tooth structure due to forces like brushing too hard or using abrasive toothpaste.

Correct Answer: C

Rationale: Using professional medical interpreters is the best approach when communicating with a patient who speaks a different language. This ensures accurate communication and helps prevent misunderstandings that can have serious consequences for the patient's health. Family members or friends may not be fluent in the necessary medical terminology and could unintentionally misinterpret information. Relying solely on written instructions can also be risky as the patient may have difficulty reading or comprehending the information. Speaking loudly and slowly may come across as disrespectful and does not address the root issue of the language barrier. Professional medical interpreters are trained to facilitate effective communication between healthcare providers and patients, ensuring that the patient receives the best possible care.

Correct Answer: C

Rationale: The demographic profile of a population encompasses various aspects, including size, distribution, composition, and change over time.

Correct Answer: D

Rationale: The assessment finding that is indicative of the diagnosis of hypertension is consistent evaluation of blood pressure. Hypertension is diagnosed based on repeated measurements of elevated blood pressure. Consistently high blood pressure readings, usually defined as systolic blood pressure consistently at or above 140 mmHg and diastolic blood pressure consistently at or above 90 mmHg, are a key factor in diagnosing hypertension. Family history of high blood pressure (Choice A), elevation of blood cholesterol level (Choice B), and a stressful work environment (Choice C) may be risk factors for hypertension but are not diagnostic criteria. In order to diagnose hypertension, healthcare providers rely on consistent measurement and evaluation of blood pressure over time.
