Nursing Elites

1. Chemicals, agents, or factors that cause physical defects in the developing embryo and are most harmful during organogenesis are:

• A. Teratogens
• B. Heterozygous
• C. Inborn errors
• D. Multifactorial

Correct answer: A

Rationale: Teratogens are substances that can cause congenital abnormalities, especially during the first trimester when organogenesis occurs. Choice A, Teratogens, is the correct answer as it specifically refers to substances that cause physical defects in the developing embryo. Choices B, Heterozygous, C, Inborn errors, and D, Multifactorial, are incorrect as they do not directly relate to substances that cause physical defects in embryos during organogenesis.

2. Picking up a pencil demonstrates the ability to use which of the following?

• A. Pincer grasp
• B. Prehension
• C. Parachute reflex
• D. Grasp reflex

Correct answer: A

Rationale: Picking up a pencil requires the use of the pincer grasp, which involves the coordination of the thumb and forefinger to hold small objects. The pincer grasp is a fine motor skill essential for tasks that necessitate precision and dexterity. Choices B, C, and D are incorrect. Prehension refers to the act of grasping or holding an object, parachute reflex is a protective response to sudden movement or loss of support, and grasp reflex is an automatic closing of the hand when an object is placed in the palm, none of which specifically relate to the action of picking up a pencil.

3. What is the first step in managing a child with anaphylaxis?

• A. Administer antihistamines
• B. Establish IV access
• C. Administer epinephrine
• D. Monitor vital signs

Correct answer: C

Rationale: The correct answer is to administer epinephrine. Administering epinephrine is the crucial first step in managing anaphylaxis as it helps reverse the severe allergic reaction by constricting blood vessels and relaxing airway muscles, preventing a life-threatening situation. Antihistamines (Choice A) are not the first-line treatment for anaphylaxis and should not delay the administration of epinephrine. Establishing IV access (Choice B) may be necessary but is not the initial step in managing anaphylaxis. Monitoring vital signs (Choice D) is important but should not take precedence over administering epinephrine in the acute management of anaphylaxis.

4. The mother of a 6-month-old infant has returned to work and is expressing breast milk to be frozen. She asks for directions on how to safely thaw the breast milk in the microwave. What should the nurse recommend?

• A. Heat only 10 oz or more.
• B. Do not thaw or heat breast milk in a microwave oven.
• C. Always leave the bottle top uncovered to allow heat to escape.
• D. Shake the bottle vigorously for at least 30 seconds after heating.

Correct answer: B

Rationale: Thawing or heating breast milk in a microwave is not recommended because it can create hot spots that may burn the infant and destroy essential nutrients.

5. A parent asks the nurse what would be the first indication that acute glomerulonephritis was improving. What would be the nurse's best response?

• A. Blood pressure will stabilize.
• B. Your child will have more energy.
• C. Urine will be free of protein.
• D. Urine output will increase.

Correct answer: D

Rationale: Increased urine output is often the first sign that acute glomerulonephritis is improving, as it indicates a reduction in fluid retention and better kidney function. Stabilization of blood pressure and other symptoms typically follow.
