HESI LPN
Adult Health 2 Final Exam
1. In a community health setting, which individual is at highest risk for contracting an HIV infection?
- A. 17-year-old who is sexually active with numerous partners
- B. 34-year-old homosexual in a monogamous relationship
- C. 30-year-old cocaine user who inhales and smokes drugs
- D. 45-year-old who has received two blood transfusions in the past 6 months
Correct answer: C
Rationale: The correct answer is C. Substance abuse, particularly using shared inhalation equipment like needles and pipes for drug inhalation, significantly increases the risk of contracting HIV. Choice A, the 17-year-old with multiple sexual partners, poses a risk of HIV transmission through sexual contact, but it is lower compared to the direct risk associated with sharing drug paraphernalia. Choice B, the 34-year-old homosexual in a monogamous relationship, is at lower risk since being in a monogamous relationship reduces exposure to HIV. Choice D, the 45-year-old who received blood transfusions, is also at lower risk as blood transfusions are now screened for HIV, decreasing the likelihood of transmission through this route.
2. A home health nurse knows that a 70-year-old male client who is convalescing at home following a hip replacement is at risk for developing decubitus ulcers. Which physical characteristic of aging contributes to such a risk?
- A. 16% increase in overall body fat.
- B. Reduced melanin production.
- C. Thinning of the skin with loss of elasticity.
- D. Calcium loss in the bones.
Correct answer: C
Rationale: Thinning of the skin with loss of elasticity is the physical characteristic of aging that contributes to an increased risk of developing decubitus ulcers. As individuals age, the skin becomes thinner and loses its elasticity, making it more susceptible to damage from pressure, leading to the formation of pressure ulcers. Choices A, B, and D are incorrect as they do not directly contribute to the development of decubitus ulcers in this context.
3. Round off these numbers to the nearest tenth:
- A. 5.5778 = 5.6, 1.027 = 1.0, 62.999 = 63, 55.123 = 55.1, 96.676 = 96.7
- B. 5.5778 = 5.6, 1.027 = 1.0, 62.999 = 63, 55.123 = 55.1, 96.676 = 96.7
- C. 5.5778 = 5.6, 1.027 = 1.0, 62.999 = 63, 55.123 = 55.1, 96.676 = 96.7
- D. 5.5778 = 5.6, 1.027 = 1.0, 62.999 = 63, 55.123 = 55.1, 96.676 = 96.7
Correct answer: B
Rationale: The correct answer is B. When rounding off to the nearest tenth, 1.027 becomes 1.0 because the digit in the hundredth's place is less than 5. For the other numbers, they are rounded correctly to the nearest tenth: 5.5778 = 5.6, 62.999 = 63, 55.123 = 55.1, 96.676 = 96.7. Therefore, option B is the most accurate in rounding off these numbers to the nearest tenth. Choices A, C, and D are incorrect as they do not round 1.027 to 1.0 as required when rounding to the nearest tenth.
4. How is gastroesophageal reflux (GER) typically treated in infants?
- A. Keeping the infant NPO
- B. Thickening the formula or breast milk with cereal
- C. Placing the infant to sleep on the side
- D. Switching the infant to cow's milk
Correct answer: B
Rationale: Thickening the formula or breast milk with cereal is a common treatment for gastroesophageal reflux (GER) in infants. By adding cereal, the feedings become heavier, making it less likely for the stomach contents to reflux. Keeping the infant NPO (nothing by mouth) is not typically necessary for GER treatment and might not be appropriate. Placing the infant to sleep on the side is not recommended due to the risk of sudden infant death syndrome (SIDS). Switching the infant to cow's milk is also not a recommended treatment for GER as it can exacerbate symptoms due to its protein content.
5. A nurse educator is presenting a module on basic first aid for newly licensed home health nurses. The client who has heat stroke will have which of the following?
- A. Hypotension
- B. Bradycardia
- C. Clammy skin
- D. Bradypnea
Correct answer: A
Rationale: The correct answer is A: Hypotension. Heat stroke is characterized by elevated body temperature, which can lead to hypotension (low blood pressure) due to dehydration and vasodilation. Bradycardia (slow heart rate) and clammy skin are not typical findings in heat stroke. Bradypnea (slow breathing) is also not a common feature of heat stroke. Therefore, hypotension is the most likely cardiovascular manifestation seen in a client with heat stroke.
