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. The UAP reports to the nurse that a client refused to bathe for the third consecutive day. Which action is best for the nurse to take?

• A. Explain the importance of good hygiene to the client
• B. Ask family members to encourage the client to bathe
• C. Reschedule the bath for the following day
• D. Ask the client why the bath was refused

Correct answer: D

Rationale: The correct action for the nurse to take is to ask the client why the bath was refused. Understanding the client's reason for refusal is crucial in identifying and addressing any underlying concerns or issues that may be contributing to the refusal. This approach promotes open communication, client-centered care, and helps in developing a plan of care that is tailored to the client's needs and preferences. Choices A, B, and C do not directly address the root cause of the refusal and may not effectively resolve the situation.

3. Which electrolyte imbalance is most commonly associated with seizures?

• A. Hyponatremia
• B. Hypercalcemia
• C. Hyperkalemia
• D. Hypokalemia

Correct answer: A

Rationale: The correct answer is A: Hyponatremia. Hyponatremia, characterized by low sodium levels in the blood, can lead to cerebral edema and seizures due to water shifting into brain cells. Hypercalcemia (choice B) does not commonly cause seizures but can result in muscle weakness and cardiac arrhythmias. Hyperkalemia (choice C) may lead to muscle weakness and cardiac arrhythmias, but it is less frequently associated with seizures. Hypokalemia (choice D) is linked to muscle weakness and cardiac arrhythmias but is not typically related to seizures.

4. What is the primary reason for applying sequential compression devices (SCDs) to a patient’s legs postoperatively?

• A. To prevent deep vein thrombosis (DVT)
• B. To promote wound healing
• C. To reduce postoperative pain
• D. To maintain body temperature

Correct answer: A

Rationale: The correct answer is A: To prevent deep vein thrombosis (DVT). Sequential compression devices (SCDs) are used postoperatively to prevent DVT by promoting blood circulation in the legs. This helps reduce the risk of blood clots forming in the deep veins of the legs. Choice B, to promote wound healing, is incorrect as SCDs are primarily used for circulatory purposes rather than wound healing. Choice C, to reduce postoperative pain, is incorrect as the primary purpose of SCDs is not pain management but rather prevention of DVT. Choice D, to maintain body temperature, is incorrect as SCDs are not designed for regulating body temperature but for preventing circulatory issues.

5. At what age does a 9-year-old child typically lose which of the following teeth?

• A. Central incisor
• B. Second molar
• C. Lateral incisor
• D. Cuspid

Correct answer: A

Rationale: A 9-year-old child typically loses their central incisors, not the lateral incisors or second molars. The central incisors are usually among the first teeth that children lose around 6 to 7 years of age, as part of the natural process of shedding primary teeth to make way for permanent teeth. The second molars and cuspids are typically lost later in the mixed dentition phase. Therefore, option A, 'Central incisor,' is the correct answer.
