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.

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.

Correct Answer: A

Rationale: The correct answer is the left lateral position. Placing the laboring client in the left lateral position is beneficial because it promotes blood flow to the placenta. Late decelerations indicate potential issues with fetal oxygenation, and changing the position to left lateral can help improve placental perfusion. Choices B, C, and D are incorrect because lithotomy, semi-Fowler's, and right lateral positions do not specifically address the need for improved blood flow to the placenta in cases of late decelerations.

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.

Correct Answer: C

Rationale: A cardiac output of 5 L/min falls within the normal range for a resting adult, which typically ranges between 4 and 6 L/min. Cardiac output is calculated as the stroke volume (volume of blood in each systole) multiplied by the heart rate. Therefore, a cardiac output of 5 L/min is considered normal. Choices A and B are incorrect as they misinterpret the result as either low or high, which is not the case based on the provided information. Choice D is unrelated to the client's cardiac output and thus incorrect.
