A client complains that her skin is redder than normal. The nurse notes the client's skin, documents hyperemia, and explains to the client that this condition is caused by which factor?
- A. Constriction of the underlying blood vessels
- B. An increased amount of bilirubin in the blood
- C. Increased perfusion of the surrounding tissues
- D. Excess blood in the dilated superficial capillaries
Correct Answer: D
Rationale: Hyperemia is an excess of blood in a part of the body. The skin over a hyperemic area usually becomes reddened or warm. The condition is caused by increased blood flow, local relaxation of arterioles, or obstruction of the outflow of blood from an area. Choice A is incorrect because constriction of blood vessels would lead to decreased blood flow, not excess blood. Choice B is incorrect as an increased amount of bilirubin in the blood is related to jaundice, not hyperemia. Choice C is incorrect because increased perfusion of the surrounding tissues would cause redness, not hyperemia.

A client asks the nurse what risk factors increase the chances of getting skin cancer. The risk factors include all except:
- A. light or fair complexion.
- B. exposure to sun for extended periods of time.
- C. certain diet and foods.
- D. history of bad sunburns.
Correct Answer: C
Rationale: The correct answer is 'certain diet and foods.' Risk factors that increase the chances of getting skin cancer include having a light or fair complexion, a history of bad sunburns, personal or family history of skin cancer, outdoor activities with sun exposure, exposure to X-rays or radiation, exposure to certain chemicals, repeated trauma or injury resulting in scars, age over 50, male gender, and living in specific geographic locations. These factors can contribute to the development of skin cancer. Avoiding exposure to the sun, using protective clothing and sunscreen, and regular skin inspections are key preventive measures. Choice C, 'certain diet and foods,' is incorrect as diet is not a primary risk factor for skin cancer. Options A, B, and D are all valid risk factors associated with an increased risk of developing skin cancer.
A healthcare professional is using an otoscope to inspect the ears of an adult client. Which action does the professional take before inserting the otoscope?
- A. Pulling the pinna up and back
- B. Pulling the pinna down and forward
- C. Tipping the client's head down and toward the examiner
- D. Tipping the client's head down and away from the examiner
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.
The LPN is taking care of a client with a documented allergy to Penicillin. After rounds, the LPN notices that the client has an order for Cefazolin. Which of the following actions would be the least appropriate?
- A. The LPN clarifies the severity of the Penicillin allergy.
- B. The LPN discusses the order with the care team prior to administering Cefazolin.
- C. The LPN administers all ordered medications except for the Cefazolin.
- D. The LPN monitors the client after a test dose of Cefazolin is administered.
Correct Answer: C
Rationale: The least appropriate action is for the LPN to administer all ordered medications except for the Cefazolin. The LPN should always consider the client's documented allergy to Penicillin seriously. It is crucial to discuss the order with the care team before administering Cefazolin to ensure patient safety. Administering a medication that could potentially cause harm due to a documented allergy is unsafe practice. While monitoring the client after a test dose of Cefazolin is important, it should not precede clarification with the care team regarding the allergy and the appropriateness of the medication. Therefore, withholding the Cefazolin is the most appropriate action in this scenario.
A healthcare provider is assisting with data collection on a client for the major risk factors associated with coronary artery disease (CAD). Which modifiable risk factor does the healthcare provider obtain data on from the client?
- A. Age
- B. Ethnicity
- C. Hypertension
- D. Genetic inheritance
Correct Answer: C
Rationale: The correct answer is 'Hypertension.' Risk factors for CAD are categorized as modifiable and unmodifiable. Unmodifiable risk factors include age, sex, ethnicity, genetic predisposition, and family history of heart disease. Modifiable risk factors include increased concentrations of serum lipids, hypertension, cigarette smoking, obesity, and level of physical activity. In this case, hypertension is a modifiable risk factor that the healthcare provider would obtain data on. Choices A, B, and D are incorrect because age, ethnicity, and genetic inheritance are unmodifiable risk factors for CAD, not modifiable ones.
During a routine office visit, which of the following developmental milestones should the nurse screen for in a 6-month-old child?
- A. standing while holding something
- B. rolling over
- C. sitting up
- D. creeping
Correct Answer: B
Rationale: The correct developmental milestone for a 6-month-old child that should be screened during a routine office visit is rolling over. At this age, infants typically start rolling over from their stomach to their back and vice versa. Sitting up usually occurs between 7 and 8 months, creeping between 9 and 10 months, and standing while holding something between 8 and 10 months. Therefore, choices A, C, and D are developmentally appropriate but not typically expected at 6 months of age.
