1. Which vitamin deficiency is most associated with night blindness?

• A. Vitamin A
• B. Vitamin B12
• C. Vitamin C
• D. Vitamin D

Correct answer: A

Rationale: The correct answer is Vitamin A. Vitamin A deficiency leads to night blindness because this vitamin is crucial for the formation of rhodopsin, a photopigment in the retina. Rhodopsin is essential for vision in low-light conditions. Vitamin B12 deficiency can lead to anemia and neurological issues but is not directly related to night blindness. Vitamin C deficiency can cause scurvy, affecting connective tissues, but not night vision. Vitamin D deficiency can lead to bone disorders but is not primarily associated with night blindness.

2. A client who had a hip replacement is being prepared for discharge. What should the nurse include in the discharge teaching to prevent hip dislocation?

• A. Avoid crossing your legs at the knees or ankles.
• B. Do not sleep on the side of the hip that was operated on.
• C. Sit in high chairs and keep your knees higher than your hips.
• D. Do not bend forward at the waist to pick up objects.

Correct answer: A

Rationale: The correct answer is A: 'Avoid crossing your legs at the knees or ankles.' Crossing legs at the knees or ankles can cause excessive stress on the new hip joint, leading to a risk of dislocation. Choice B is incorrect because sleeping on the side of the operated hip can also increase the risk of dislocation. Choice C is incorrect as sitting in low chairs with knees higher than hips is a recommended position to prevent hip dislocation. Choice D is incorrect because bending forward at the waist to pick up objects can strain the hip joint and increase the risk of dislocation.

3. Which of the following is MOST LIKELY to increase the risk of a medication error?

• A. Not using abbreviations for medications
• B. Errors in the calculation of medication dosages
• C. Barcoding medication orders
• D. Utilizing unit dose dispensers

Correct answer: B

Rationale: Errors in the calculation of medication dosages are a significant risk factor for medication errors. When dosage calculations are incorrect, it can lead to administering the wrong amount of medication, posing serious harm to the patient. Avoiding abbreviations for medications, barcoding medication orders, and utilizing unit dose dispensers are all strategies aimed at reducing medication errors by enhancing accuracy and safety. Therefore, choices A, C, and D are incorrect as they are practices that help decrease, rather than increase, the risk of medication errors.

4. Which of the following is the most effective way to prevent the spread of infection in a healthcare setting?

• A. Using sterile gloves
• B. Wearing a face mask
• C. Performing hand hygiene
• D. Using disposable equipment

Correct answer: C

Rationale: Performing hand hygiene is the most effective way to prevent the spread of infection in a healthcare setting. Hand hygiene helps remove pathogens that could be transmitted through direct contact, making it a crucial practice in infection control. While using sterile gloves and disposable equipment are important in certain situations, they do not address the potential transmission of pathogens through direct contact, unlike hand hygiene. Wearing a face mask is important for respiratory precautions but may not be as effective as hand hygiene in preventing the spread of infections through direct contact.

5. What is the most common cause of acute pancreatitis?

• A. Gallstones
• B. Alcohol abuse
• C. Hypertriglyceridemia
• D. Infection

Correct answer: A

Rationale: The correct answer is A: Gallstones. Gallstones are the most common cause of acute pancreatitis as they obstruct the pancreatic duct, leading to inflammation. While alcohol abuse (Choice B) can also cause pancreatitis, gallstones are more prevalent. Hypertriglyceridemia (Choice C) is a less common cause of acute pancreatitis compared to gallstones. Infection (Choice D) is not a primary cause of acute pancreatitis; gallstones are the leading etiology.
