Nursing Elites

1. During which of the following periods does the development of arms and legs occur in a pregnancy?

• A. Development of the lungs
• B. Development of the heart
• C. Development of arms and legs
• D. Development of the stomach

Correct answer: C

Rationale: The correct answer is C. The development of arms and legs occurs during the critical period of the fourth to eighth weeks of pregnancy. This timeframe is crucial for the formation of limbs and other key body parts. Choices A, B, and D are incorrect because the development of the lungs, heart, and stomach respectively occurs at different stages of fetal development and is not primarily associated with the fourth to eighth weeks of pregnancy.

2. When both alleles' effects are shown, there is said to be:

• A. codominance.
• B. preponderance.
• C. ascendance.
• D. concurrence.

Correct answer: A

Rationale: The correct answer is A: codominance. Codominance refers to a genetic scenario where both alleles in a gene pair are fully expressed, leading to a phenotype that displays traits from both alleles equally. This is distinct from incomplete dominance where the traits blend. Choices B, C, and D are incorrect. Preponderance does not specifically relate to the expression of alleles. Ascendance and concurrence do not describe the genetic concept of codominance where both alleles are fully expressed.

3. What is the primary rationale for thoroughly drying the infant immediately after birth?

• A. Stimulates crying and lung expansion.
• B. Removes maternal blood from the skin surface.
• C. Reduces heat loss from evaporation.
• D. Increases blood supply to the hands and feet.

Correct answer: C

Rationale: The primary rationale for thoroughly drying the infant immediately after birth is to reduce heat loss from evaporation. This helps maintain the infant's body temperature and prevent hypothermia. Choice A (Stimulates crying and lung expansion) is incorrect because drying the infant is not primarily done to stimulate crying but rather to prevent heat loss. Choice B (Removes maternal blood from the skin surface) is incorrect as the main reason is to prevent heat loss, not to remove maternal blood. Choice D (Increases blood supply to the hands and feet) is also incorrect as drying the infant is not intended to increase blood supply but rather to regulate body temperature.

4. A client who is pregnant and follows a vegan diet asks a nurse for guidance on foods high in calcium. Which of the following foods has the highest amount of calcium?

• A. ½ cup cubed avocado
• B. 1 large banana
• C. 1 medium potato
• D. 1 cup cooked broccoli

Correct answer: D

Rationale: The correct answer is D: 1 cup of cooked broccoli. Broccoli is an excellent source of calcium, making it a suitable choice for a vegan diet. Avocado (Choice A), banana (Choice B), and potato (Choice C) are not significant sources of calcium compared to broccoli. Avocado and banana are primarily sources of other nutrients like healthy fats and potassium, respectively. Potato is a good source of vitamin C and potassium but not calcium. Therefore, for a pregnant client following a vegan diet and seeking calcium-rich foods, cooked broccoli is the most appropriate choice.

5. When should a nurse on a labor and delivery unit instruct a newly licensed nurse to don gloves for a procedure?

• A. Assisting a mother with breastfeeding
• B. Performing a newborn's initial bath
• C. Administering the measles, mumps, rubella vaccine
• D. Performing umbilical cord care

Correct answer: B

Rationale: The correct answer is B: Performing a newborn's initial bath. Gloves should be worn during this procedure to protect against exposure to body fluids, such as amniotic fluid or blood. Assisting a mother with breastfeeding (Choice A) does not typically require gloves unless there are specific reasons for infection control. Administering vaccines (Choice C) and performing umbilical cord care (Choice D) are procedures that may require hand hygiene but not necessarily gloves, unless there is active bleeding or potential exposure to body fluids. The initial bath involves direct contact with body fluids, making it crucial to wear gloves for protection.
