1. A client is prescribed alendronate (Fosamax) for the treatment of osteoporosis. Which instruction should the nurse provide to the client?
- A. Take the medication at bedtime.
- B. Take the medication with a full glass of water.
- C. Lie down for 30 minutes after taking the medication.
- D. Take the medication with food to avoid gastrointestinal upset.
Correct answer: B
Rationale: The correct instruction for a client prescribed alendronate (Fosamax) for osteoporosis is to take the medication with a full glass of water first thing in the morning. It should be taken at least 30 minutes before any food, beverage, or other medication. The client should also remain upright for at least 30 minutes after taking the medication to prevent esophageal irritation. Taking alendronate at bedtime or with food is not recommended as it may reduce its absorption and effectiveness.
2. A new mother calls the nurse stating that she wants to start feeding her 6-month-old child something besides breast milk, but is concerned that the infant is too young to start eating solid foods. How should the nurse respond?
- A. Advise the mother to wait at least another month before starting any solid foods.
- B. Instruct the mother to offer a few spoons of 2 or 3 pureed fruits at each meal.
- C. Reassure the mother that the infant is old enough to eat iron-fortified cereal.
- D. Encourage the mother to schedule a developmental assessment of the infant.
Correct answer: C
Rationale: At 6 months, infants are generally ready to start eating iron-fortified cereals as their iron stores begin to deplete. Introducing iron-fortified cereals at this age helps meet the infant's nutritional needs, particularly for iron, which becomes deficient as the infant's iron reserves diminish. It is a safe and appropriate first food to introduce to infants around 6 months of age, along with continued breastfeeding or formula feeding. Choice A is incorrect because waiting another month is not necessary if the infant is 6 months old. Choice B is incorrect as introducing pureed fruits as the first food may not provide the necessary iron that the infant needs at this stage. Choice D is also incorrect as scheduling a developmental assessment is not indicated solely based on the desire to start solid foods; it is more appropriate to reassure the mother about starting iron-fortified cereal.
3. What are the nitrogenous bases of DNA?
- A. Adenine, cytosine, guanine, and thymine
- B. Adenine, guanine, and uracil
- C. Adenine, guanine, and thymine
- D. Adenine, cytosine, guanine, and uracil
Correct answer: A
Rationale: The correct answer is A: Adenine, cytosine, guanine, and thymine. These are the four nitrogenous bases found in DNA. Adenine pairs with thymine, and cytosine pairs with guanine, forming the complementary base pairs in the double helix structure of DNA. Choice B is incorrect because uracil is a nitrogenous base found in RNA, not DNA. Choice C is incorrect as it is missing cytosine, one of the four bases in DNA. Choice D is incorrect because uracil is not a nitrogenous base in DNA, and it also lacks thymine, which is essential for DNA structure.
4. During a well-baby check, the nurse hides a block under the baby's blanket, and the baby looks for the block. Which normal growth and development milestone is the baby developing?
- A. Separation anxiety.
- B. Associative play.
- C. Object prehension.
- D. Object permanence.
Correct answer: D
Rationale: When a baby looks for a hidden object, it demonstrates the development of object permanence. This milestone is significant as it signifies the baby's understanding that objects continue to exist even when they are not visible. It is a crucial aspect of cognitive development in infancy. Choice A, separation anxiety, refers to distress when separated from a primary caregiver and is not demonstrated in this scenario. Choice B, associative play, involves interactive play with others and is not relevant to object search. Choice C, object prehension, refers to the ability to grasp and hold objects, which is not specifically demonstrated by looking for a hidden object in this context.
5. The nurse is caring for a client undergoing the placement of a central venous catheter line. Which of the following would require the nurse's immediate attention?
- A. Pallor
- B. Increased temperature
- C. Dyspnea
- D. Involuntary muscle spasms
Correct answer: C
Rationale: Dyspnea indicates a potential complication such as pneumothorax or incorrect catheter placement, requiring immediate attention. Pallor may indicate anemia but is not as urgent as dyspnea in this context. Increased temperature could be a sign of infection but is not as critical as respiratory distress. Involuntary muscle spasms are not directly related to central venous catheter placement and are of lower priority compared to respiratory issues.
