HESI Fundamentals Study Guide

Correct Answer: D

Rationale: Applying a hydrocolloid or foam dressing is the most effective treatment to promote healing for a Stage 2 skin ulcer. These dressings create a moist environment that supports healing and prevents further tissue damage. Option A (covering the wound with a dry dressing) can lead to drying out the wound bed, hindering healing. Option B (using hydrogen peroxide soaks) can be too harsh and may damage the surrounding healthy tissue. Option C (leaving the area open to dry) can delay healing as it does not provide the necessary moist environment for optimal wound healing.

Correct Answer: D

Rationale: The correct answer is D. A potassium level of 5.4 mEq/L is above the expected reference range, indicating hyperkalemia. Hyperkalemia can lead to serious complications such as dysrhythmias, making it important for the healthcare professional to report this finding to the provider for further evaluation and intervention. Choices A, B, and C fall within normal ranges and do not pose an immediate risk to the client's health, so they would not warrant immediate reporting to the provider. Elevated BUN or creatinine levels may indicate kidney dysfunction, while a sodium level of 143 mEq/L falls within the normal range for adults and does not typically require urgent intervention.

Correct Answer: C

Rationale: Comparing the client's wristband with the medication administration record is a crucial step in ensuring medication safety. The wristband typically contains unique identifiers such as the client's name, date of birth, and medical record number, which should be cross-checked with the medication administration record to confirm the correct patient. Asking the client to state their name (Choice A) or date of birth (Choice B) may not be as reliable as the information can be misunderstood or miscommunicated. Asking for the room number (Choice D) is not a reliable client identifier for medication administration and does not confirm the patient's identity accurately.

Correct Answer: C

Rationale: The correct side effect that the LPN/LVN should monitor for in a client prescribed a beta-blocker is bradycardia. Beta-blockers work by slowing down the heart rate, which can lead to bradycardia as a common side effect. Monitoring the client's heart rate is crucial, as bradycardia can be a serious condition. Choices A, B, and D are incorrect because increased appetite, dry mouth, and insomnia are not typically associated with beta-blockers. Increased appetite is more commonly linked to certain medications like corticosteroids, dry mouth can be a side effect of anticholinergic medications, and insomnia may be a side effect of stimulant medications.

Correct Answer: B

Rationale: The correct answer is B, a lactating woman nursing her 3-day-old infant. During lactation, women have increased nutritional needs, including protein, to support milk production for their infants. Protein is essential for proper growth and development. While choice A, a college-age track runner with a sprained ankle, may require protein for tissue repair, the lactating woman's need is greater due to the demands of breastfeeding. Choice C, a school-aged child with Type 2 diabetes, may have specific dietary considerations related to diabetes management but does not necessarily require additional protein intake compared to a lactating woman. Choice D, an elderly man being treated for a peptic ulcer, may need protein for wound healing, but the nutritional need for a lactating woman is higher to support her infant's growth.
