1. Fatty acids may differ from one another:
- A. in chain length
- B. in degree of saturation
- C. in number of calories
- D.
Correct answer: D
Rationale: Fatty acids vary in chain length and degree of saturation, affecting their physical properties and health effects.
2. A healthcare professional is reviewing laboratory data for a client who has chronic kidney disease. Which of the following findings should the healthcare professional expect?
- A. Increased creatinine.
- B. Increased hemoglobin.
- C. Increased bicarbonate.
- D. Increased calcium.
Correct answer: Increased creatinine.
Rationale: In chronic kidney disease, the kidneys are unable to effectively filter waste products from the blood, leading to an accumulation of creatinine. Creatinine levels are commonly elevated in individuals with impaired kidney function, making it a key indicator of kidney health. Therefore, an increased creatinine level would be an expected finding in a client with chronic kidney disease.
3. A home care nurse is visiting a client with a diagnosis of pernicious anemia that developed as a result of gastric surgery. The nurse instructs the client that because the stomach lining produces a decreased amount of intrinsic factor in this disorder, the client will need
- A. Vitamin B12 injections.
- B. Vitamin B6 injections.
- C. An antibiotic.
- D. An antacid.
Correct answer: A
Rationale: A lack of the intrinsic factor needed to absorb vitamin B12 occurs in pernicious anemia. Vitamin B12 is needed for the maturation of red blood cells. Vitamin B6 is not necessarily needed for pernicious anemia and can be taken orally. An antibiotic and antacids may be prescribed for certain types of gastric ulcers.
4. A client who is taking phenytoin is being taught about contraceptive options. Which of the following statements should the nurse make?
- A. You should use a backup method of birth control while taking phenytoin.
- B. Phenytoin can decrease the effectiveness of oral contraceptives.
- C. You should stop taking phenytoin while using oral contraceptives.
- D. Phenytoin can increase the effectiveness of oral contraceptives.
Correct answer: B
Rationale: The correct answer is B. Phenytoin can decrease the effectiveness of oral contraceptives, so it is important to inform the client about this interaction. Using an additional form of contraception, such as a backup method, is recommended to ensure adequate protection against pregnancy. Choice A is incorrect because it lacks specificity about the decrease in effectiveness of oral contraceptives caused by phenytoin. Choice C is incorrect as it suggests stopping phenytoin use while using oral contraceptives, which is not the appropriate action. Choice D is incorrect as phenytoin is known to decrease, not increase, the effectiveness of oral contraceptives.
5. A nurse is planning care for a client who has a new prescription for a peripheral intravenous (IV) catheter. Which of the following actions should the nurse take to prevent infection?
- A. Shave the hair at the insertion site.
- B. Cleanse the site with povidone-iodine.
- C. Wear sterile gloves when changing the dressing.
- D. Change the IV site every 48 to 72 hours.
Correct answer: D
Rationale: The correct action to prevent infection when caring for a client with a new peripheral IV catheter is to change the IV site every 48 to 72 hours. Shaving the hair at the insertion site can actually increase the risk of infection by causing microabrasions in the skin. While cleansing the site with povidone-iodine is important before insertion, it is not necessary to continue doing so once the IV is in place. Wearing sterile gloves when changing the dressing is crucial for maintaining aseptic technique but does not directly prevent infection related to the IV site itself.
