When taking a child's blood pressure, what percentage of the upper arm should the nurse ensure the cuff bladder width covers?
- A. 20%
- B. 40%
- C. 60%
- D. 80%
Correct Answer: B
Rationale: When taking a child's blood pressure, the nurse should select a cuff with a bladder width that covers 40% of the arm circumference at the midpoint of the upper arm. This ensures accurate readings. Choosing a cuff that covers less or more than 40% can lead to incorrect blood pressure measurements. Therefore, options A, C, and D are incorrect.

When teaching a discipline class for parents of pre-schoolers, the nurse will be guided by which principle?
- A. Using the strictest form of punishment at the time of infraction is most effective
- B. Punishment increases unwanted behavior
- C. Discipline is to teach and gradually shift control from parents to child, promoting self-discipline
- D. Discipline and punishment are the same
Correct Answer: C
Rationale: The correct principle to guide the nurse when teaching a discipline class for parents of pre-schoolers is that discipline is meant to teach and gradually shift control from parents to the child, promoting self-discipline. This approach focuses on educating children on appropriate behavior rather than solely relying on punishment. Choice A is incorrect because using the strictest punishment is not the most effective method for discipline. Choice B is incorrect because punishment can reinforce unwanted behavior if not used appropriately. Choice D is incorrect because discipline and punishment are not synonymous; discipline involves a broader aspect of teaching and guiding behavior.
According to Maslow's hierarchy, what is the most advanced need provided by the home environment?
- A. Love
- B. Self-actualization
- C. Esteem
- D. Physiological
Correct Answer: B
Rationale: The correct answer is B, self-actualization. Self-actualization is the highest level in Maslow's hierarchy of needs, representing the realization of one's full potential. While love is an essential need, self-actualization builds upon the fulfillment of basic needs like safety and love. Esteem needs relate to feelings of accomplishment and recognition, which come before self-actualization. Physiological needs such as food, water, and shelter are the most basic needs at the bottom of the hierarchy.
Which parental statement at the conclusion of a teaching session regarding environmental controls for childhood asthma indicates correct understanding of the information presented?
- A. ''We're glad the dog can continue to sleep in our child's room.''
- B. ''We'll keep the plants in our child's room dusted.''
- C. ''We'll be sure to use the fireplace often to keep the house warm in the winter.''
- D. ''We will replace the carpet in our child's bedroom with a hard surface.''
Correct Answer: D
Rationale: The correct answer is D. Replacing carpet with hard flooring helps to reduce allergens and asthma triggers in the child's environment. Choice A is incorrect as having a dog in the child's room can worsen asthma symptoms due to pet dander. Choice B is incorrect because keeping plants in the child's room can increase mold spores and allergens. Choice C is incorrect as using a fireplace can introduce smoke and other irritants into the air, worsening asthma symptoms.

- A. Chordee
- B. Phimosis
- C. Epispadias
- D. Hypospadias
Correct Answer: B
Rationale: Phimosis is the condition where the foreskin cannot be fully retracted over the glans penis due to a narrowing of the preputial opening. Chordee, epispadias, and hypospadias are different conditions involving the penis's structure.
A teen with asthma asks the nurse why it is hard to breathe during an asthma attack. The nurse explains that exposure to a "trigger" results in which of these manifestations?
- A. Bronchodilation, muscle relaxation, and decreased mucus production
- B. Air trapping and hypo-inflation of the alveoli
- C. Air trapping and decreased blood flow to the upper airway
- D. Bronchoconstriction, airway inflammation, and excess mucus production
Correct Answer: D
Rationale: The correct answer is D. Asthma triggers cause bronchoconstriction, airway inflammation, and increased mucus production, leading to difficulty breathing. This combination of manifestations results in narrowing of the airways, making it hard for the individual to breathe effectively. Choices A, B, and C are incorrect because during an asthma attack, bronchodilation, muscle relaxation, and decreased mucus production do not occur. Instead, the airways constrict, become inflamed, and produce excess mucus, contributing to the breathing difficulties experienced by individuals with asthma.
