Correct Answer: D

Rationale: Objective data in a physical examination are findings that the healthcare provider observes or measures directly. In this case, a 1 × 2-inch scar present on the lower right portion of the abdomen is a physical observation. Subjective data are based on what the client reports, such as allergies (Choice A), the date of the last menstrual period (Choice B), and self-reported medication use for headaches (Choice C). While these pieces of information are important for assessing the client's health, they are considered subjective data because they rely on the client's self-report rather than direct observation by the healthcare provider.

Correct Answer: D

Rationale: The correct answer is 'Dysphagia.' Dysphagia is the term used to indicate difficulty swallowing, which can occur in disorders of the throat or esophagus. Anorexia refers to a loss of appetite, not difficulty swallowing. Eructation is the medical term for belching, not difficulty swallowing. Pyrosis is heartburn, a burning sensation in the esophagus and stomach caused by the reflux of gastric acid, not difficulty swallowing.

Correct Answer: D

Rationale: The correct answer is the Wong-Baker Pain Scale. This scale is specifically designed for pediatric clients, including children as young as 3 years old, making it the most appropriate choice for a 4-year-old. It utilizes a simple visual scale with facial expressions that children can easily understand and use to express their pain levels. The FLACC and CRIES Pain Scales are also used for pediatric clients but are more focused on non-verbal cues and specific populations like infants or critically ill children. The McGill Pain Scale, on the other hand, is more complex and uses descriptive words, making it more suitable for adult clients who can better articulate their pain experiences.

Correct Answer: D

Rationale: The correct actions for the LPN to perform for a client with an active digoxin IV order are to monitor ECG rhythm throughout administration and monitor the client's pulse for 1 minute prior to administration. These actions are crucial as digoxin affects the heart's electrical activity, and it should not be administered if the client's pulse is less than 60 bpm. Monitoring respirations and blood pressure are not directly associated with digoxin administration. Administering IV medications is typically outside the LPN's scope of practice.

Correct Answer: A

Rationale: In an adult client, the healthcare professional should pull the pinna up and back before inserting the otoscope. This action helps straighten the S shape of the ear canal, making it easier to insert the otoscope directly and comfortably. Tipping the client's head down and toward or away from the examiner is not the correct action when using an otoscope in an adult. Pulling the pinna down and forward is typically done when examining an infant or a child younger than 3 years old to straighten their ear canal for better visualization.
