1. What do the following ABG values indicate: pH 7.38, PO2 78 mmHg, PCO2 36 mmHg, and HCO3 24 mEq/L?
- A. metabolic alkalosis
- B. homeostasis
- C. respiratory acidosis
- D. respiratory alkalosis
Correct answer: B
Rationale: The correct answer is 'homeostasis.' These ABG values fall within the normal range, indicating a state of balance and homeostasis. The pH is within the normal range (7.35-7.45), the PCO2 is normal (35-45 mmHg), and the HCO3 level is also normal (22-26 mEq/L). Choice A, 'metabolic alkalosis,' is incorrect because the pH, PCO2, and HCO3 levels are not indicative of metabolic alkalosis. Choice C, 'respiratory acidosis,' is incorrect as the pH and PCO2 values are not elevated. Choice D, 'respiratory alkalosis,' is incorrect as the pH and PCO2 levels are not decreased. Therefore, the ABG values provided do not correspond to any acid-base disturbance, confirming that the patient is in a state of homeostasis.
2. How can a diet high in fiber content benefit an individual?
- A. aid in rapid weight loss.
- B. reduce diabetic ketoacidosis.
- C. lower cholesterol.
- D. reduce the requirement for folate.
Correct answer: C
Rationale: A diet high in fiber content can help lower cholesterol levels. Fiber-rich foods such as grains, apples, potatoes, and beans are known to aid in reducing cholesterol by binding to cholesterol in the digestive system and preventing its absorption into the bloodstream. Choice A is incorrect as the question does not specify losing weight rapidly but rather focuses on the benefits of a high-fiber diet, which includes aiding in weight management through promoting satiety and regulating digestion. Choice B is incorrect because while fiber helps manage blood sugar levels, it is not directly related to reducing diabetic ketoacidosis, a serious complication of diabetes. Choice D is incorrect as a high-fiber diet does not reduce the need for folate; however, it can aid in the absorption of folate and other essential nutrients.
3. A nurse is taking the health history of an 85-year-old client. Which of the following physical findings is consistent with normal aging?
- A. Increase in subcutaneous fat.
- B. Diminished cough reflex.
- C. Long-term memory loss.
- D. Myopia.
Correct answer: B
Rationale: The correct answer is 'Diminished cough reflex.' Diminished cough reflex is a physical finding consistent with normal aging in older adults, which can increase the risk of aspiration and atelectasis. An increase in subcutaneous fat actually raises the risk of pressure ulcers. While long-term memory is typically preserved in aging unless affected by dementia, short-term memory often declines. Myopia (near-sightedness) is common in younger individuals, but presbyopia (far-sightedness) is more common with aging. Additionally, individuals with myopia may experience an improvement in vision as they age.
4. A client with urinary tract calculi needs to avoid which of the following foods?
- A. lettuce
- B. cheese
- C. apples
- D. broccoli
Correct answer: B
Rationale: A client with urinary tract calculi needs to avoid foods high in calcium to prevent the formation of more stones. Cheese is high in calcium, so it should be avoided. Lettuce, apples, and broccoli are not typically associated with high calcium content and are safe options for individuals with urinary tract calculi. Therefore, the correct answer is cheese. Choices A, C, and D are not high in calcium and are safe for consumption by individuals with urinary tract calculi.
5. Which of the following microorganisms is easily transmitted from client to client on the hands of healthcare workers?
- A. mycobacterium tuberculosis
- B. clostridium tetani
- C. staphylococcus aureus
- D. human immunodeficiency virus
Correct answer: C
Rationale: The correct answer is staphylococcus aureus. Staphylococcus aureus microorganisms are ubiquitous and easily transmitted by healthcare workers who fail to conduct routine hand washing between clients. Staphylococcus aureus can reside on the skin and be transferred from one client to another if proper hand hygiene is not practiced. Mycobacterium tuberculosis is mainly transmitted through the airborne route, clostridium tetani is usually acquired through exposure to soil or dirt contaminated with tetanus spores, and human immunodeficiency virus is not easily transmitted through casual contact or on the hands of healthcare workers.
