Nursing Elites

1. What statement is most descriptive of Meckel diverticulum?

• A. It is present from birth.
• B. Intestinal bleeding may be mild or profuse.
• C. It occurs with equal frequency in both genders.
• D. Surgical interventions are always necessary to treat the problem.

Correct answer: B

Rationale: The correct answer is B. Meckel diverticulum often presents with intestinal bleeding, which can vary in severity. It is a congenital condition, meaning it is present from birth, not acquired during childhood (choice A). Meckel diverticulum is slightly more common in males than in females, so it does not occur more frequently in females (choice C). While some cases of Meckel diverticulum may require surgical intervention, medical interventions can also be sufficient to treat the problem, so it is not always necessary to resort to surgery (choice D).

2. How is family systems theory best described?

• A. The family is viewed as the sum of individual members
• B. A change in one family member cannot create a change in other members
• C. Individual family members are readily identified as the source of a problem
• D. When the family system is disrupted, change can occur at any point in the system

Correct answer: D

Rationale: Family systems theory views the family as a whole, where changes in one member affect the entire system, and changes can occur at any point within the system.

3. The nurse is preparing to administer a prescribed, as-needed antiemetic drug for a child diagnosed with cancer. Which action by the nurse is most appropriate?

• A. Administering the drug only if the child is nauseated.
• B. Administering the drug prophylactically before the next dose of chemotherapy.
• C. Administering the drug after the next dose of chemotherapy.
• D. Administering the drug only if the child is experiencing diarrhea.

Correct answer: B

Rationale: Administering the antiemetic prophylactically before the next dose of chemotherapy is the most appropriate action. This approach helps prevent nausea and vomiting associated with chemotherapy. Waiting until the child is already nauseated, as stated in option A, is less effective as it is reactive rather than proactive. Administering the drug after chemotherapy, as in option C, may not be as beneficial in preventing chemotherapy-induced nausea and vomiting. Option D, administering the drug only if the child is experiencing diarrhea, is not relevant to the prevention of chemotherapy-induced nausea.

4. Why are neonates predisposed to problems with thermoregulation?

• A. Renal function is not fully developed
• B. Flexed posture favors heat loss
• C. A large body surface area favors heat loss to the environment
• D. A thick layer of subcutaneous fat provides excellent insulation

Correct answer: C

Rationale: Newborns have a large surface area relative to their body weight, making them more susceptible to heat loss and requiring careful thermoregulation. Choice A is incorrect because renal function is not directly related to thermoregulation. Choice B is incorrect because a flexed posture actually helps reduce heat loss by minimizing the surface area exposed to the environment. Choice D is incorrect because neonates have limited subcutaneous fat, which contributes to their susceptibility to heat loss.

5. Which reflex is expected to disappear by 4 months of age?

• A. Rooting reflex
• B. Moro reflex
• C. Babinski reflex
• D. Palmar grasp

Correct answer: B

Rationale: The Moro reflex, also known as the startle reflex, typically disappears by 4 months as the infant's nervous system matures. This reflex is important for assessing the development of the nervous system in newborns. The Rooting reflex (Choice A) is related to turning the head in response to cheek stimulation; the Babinski reflex (Choice C) involves the fanning of toes in response to foot stimulation; and the Palmar grasp (Choice D) is the curling of the fingers around an object placed in the infant's hand. These reflexes have different timelines for disappearance and are not typically expected to be gone by 4 months of age.
